`More particularly, a prior art control system 100 includes a
`plurality of sensor/actuators 111, 112, 113, 114, 115, 116 and
`117 electrically and physically coupled to a local controller
`110. In a manner well known in the art of control systems,
`local controller 110 provides power, formats and applies
`data signals from each of the sensors to predetermined
`process control functions, and returns control signals as
`appropriate to the system actuators. Often, prior art control
`systems are further integrated via the public switched tele-
`10 phone network (PSTN) 120 to a central controller 130.
`Central controller 130 can also serve as a technician moni(cid:173)
`toring station and/or forward alarm conditions via PSTN 120
`to appropriate officials.
`Prior art control systems similar to that of FIG. 1 require
`the development and installation of an application-specific
`local system controller. In addition, each local system
`requires the direct coupling of electrical conductors to each
`sensor and actuator to the local system controller. Such prior
`art control systems are typically augmented with a central
`controller 130 that may be networked to the local controller
`110 via PSTN 120. As a result, prior art control systems
`often are susceptible to a single point of failure if local
`controller 110 goes out of service. Also, appropriately wiring
`an existing industrial plant can be a dangerous and expen(cid:173)
`sive proposition.
`Accordingly, there is a need for monitoring and control
`systems that overcome the shortcomings of the prior art.
`
`FIELD OF THE INVENTION
`
`The present invention generally relates to remotely oper(cid:173)
`ated systems, and more particularly to a computerized 30
`system for monitoring, controlling and reporting on remote
`systems by transferring information via radio frequency
`(RF) signals by a message protocol system.
`
`BACKGROUND
`
`There are a variety of systems for monitoring and con(cid:173)
`trolling manufacturing processes, inventory systems, emer(cid:173)
`gency control systems, etc. Most automatic systems use
`remote sensors and controllers to monitor and automatically
`respond to system parameters to reach desired results. A
`number of control systems utilize computers to process
`sensor outputs, to model system responses, and to control
`actuators that implement process corrections within the
`system. Both the electric power generation and metallurgical
`processing industries successfully control production pro(cid:173)
`cesses by implementing computer control systems in indi(cid:173)
`vidual plants.
`For example, many environmental and safety systems
`require real-time monitoring. Heating, ventilation, and air(cid:173)
`conditioning systems (HVAC), fire reporting and suppres(cid:173)
`sion systems, alarm systems, and access control systems
`utilize real-time monitoring and often require immediate
`feedback and control.
`A problem with expanding the use of control system
`technology is the cost of the sensor/actuator infrastructure
`required to monitor and control such systems. The typical
`approach to implementing control system technology
`includes installing a local network of hard-wired sensor(s)/
`actuator(s) and a local controller. There are expenses asso- 60
`ciated with developing and installing the appropriate sensor
`(s)/actuator(s) and connecting functional sensor(s)/actuator
`(s) with the local controller. Another prohibitive cost of
`control systems is the installation and operational expenses
`associated with the local controller.
`FIG. 1 sets forth a block diagram illustrating certain
`fundamental components of a prior art control system 100.
`
`65
`
`The present invention is directed to a system and method
`of monitoring and controlling remote devices. More
`specifically, the present system is directed to a computerized
`system for monitoring and controlling remote devices by
`35 transmitting data between the remote systems and a gateway
`interface via a packet message protocol system.
`The system comprises one or more remote sensors to be
`read and possibly one or more actuators to be remotely
`controlled. The remote sensor(s)/actuator(s) then interface
`40 with uniquely identified remote transceivers that transmit
`and/or receive data. If necessary in individual applications,
`signal repeaters may relay information between the
`transceiver(s) and the gateway interface. Communication
`links between the remote transceivers and the gateway
`45 interface are preferably wireless but may also be imple(cid:173)
`mented via a mixture of wireless and wired communication
`links.
`To successfully communicate between the transceiver(s)
`and the gateway interface, the present invention receives a
`50 plurality of RF signal transmissions containing a packet
`protocol via RF signals that includes sender and receiver
`identifiers, a description of the packet itself, a message
`number, any commands, the data, and an error detector. In
`addition, the packet protocol can be easily integrated with
`55 alternate data communication protocols for use with systems
`other than the Internet.
`Also, the present invention can be easily integrated into an
`existing control system via networked wireless transceivers.
`Distinct control signals from the pre-existing system are
`easily mapped into the packet protocol. This allows the
`present invention to be integrated into a pre-existing control
`system easily and inexpensively.

`log detector, in combination with digital automatic gain
`control (AGC) provide robust performance in the presence
`of channel noise or interference. Two stages of surface
`acoustic wave (SAW) filtering provide excellent receiver
`out-of-band rejection. The transmitter includes provisions
`for both on-off keyed (OOK) and amplitude-shift key (ASK)
`modulation. The transmitter employs SAW filtering to sup(cid:173)
`press output harmonics, for compliance with FCC and other
`regulations.
`Additional details of the TRlOOO transceiver need not be
`described herein, because the present invention is not lim(cid:173)
`ited by the particular choice of transceiver. Indeed, numer(cid:173)
`ous RF transceivers may be implemented in accordance with
`the teachings of the present invention. Such other transceiv-
`15 ers may include other 900 MHz transceivers, as well as
`transceivers at other frequencies. In addition
`infrared
`ultrasonic, and other types of wireless transceiv~rs may b~
`employed, consistent with the broad scope of the present
`invention. Further details of the TRlOOO transceiver may be
`20 obtained through data sheets, application notes, design
`guides (e.g., the "ASH Transceiver Designers Guide"), and
`other publications known by those skilled in the art.
`The control system 200 also can include a plurality of
`stand-alone transceivers 211, 213, 215 and 221. Each of the
`25 stand-alone transceivers 211, 213, 215 and 221 and each of
`the integrated transceiver 212, 214, 216, 222, and 224 can
`receive an incoming RF transmission and transmit an out(cid:173)
`going signal. This outgoing signal may be another low
`power RF transmission signal, a higher power RF transmis-
`sion signal, or together with alternative embodiments may
`be transmitted over a conductive wire, a fiber optic cable, or
`other transmission media. It will be appreciated by those
`skilled in the art that the integrated transceivers 212 214
`216, 222 and 224 can be replaced by RF transmitter~ (no~
`shown) for client specific applications that require continu-
`ous data collection only.
`The local gateways 210 and 220 can receive remote data
`transmissions from one or more of the stand-alone trans-
`40 ceivers 211, 213, 215, and 221 or one or more of the
`integrated transceivers 212, 214, 216, 222, and 224. The
`local gateways 210 and 220 analyze the transmissions
`received, convert the transmissions into TCP/IP format, and
`further communicate the remote data signal transmissions
`45 via the WAN 230. In this regard, the local gateways 210 and
`220 may communicate information, service requests, control
`signals, etc. to the remote integrated transceivers 212, 214,
`216, 222, and 224, from the server 260, the laptop computer
`240, and/or the workstation 250 across the WAN 230. The
`50 server 260 can be further networked with the database server
`270 to record client specific data. Further information
`regarding the integration of the invention into the WAN can
`be found in the commonly assigned U.S. utility patent
`application entitled, "System and Method for Monitoring
`and Controlling Residential Devices," issued Ser. No.
`09/704,150.
`It will be appreciated by those skilled in the art that if an
`integrated transceiver (either of 212, 214, 216, 222, and 224)
`is located sufficiently close to one of the local gateways 210
`or 220 such that the integrated transceiver's outgoing signal
`can be received by a gateway, the outgoing signal need not
`be processed and repeated through one of the stand-alone
`transceivers 211, 213, 215, or 221.
`It will be further appreciated that a monitoring system
`constructed in accordance with the teachings of the present
`invention may be used in a variety of environments. In
`accordance with a preferred embodiment, a monitoring

`
`Having summarized the invention above, reference is now
`made in detail to the description of the invention as illus(cid:173)
`trated in the drawings. While the invention will be described
`in connection with these drawings, there is no intent to limit
`it to the embodiment or embodiments disclosed therein. On
`the contrary, the intent is to cover all alternatives, modifi(cid:173)
`cations and equivalents included within the spirit and scope
`of the invention as defined by the appended claims.
`FIG. 2 sets forth a block diagram that illustrates an
`embodiment of a control system in accordance with the
`present invention. The control system 200 may consist of
`one or more transceivers. An exemplary transceiver 205 can
`be integrated with a sensor 224 to form a first combination.
`A second transceiver 207 can be integrated with an actuator
`222 to form a second combination. The transceivers 205,
`207 may preferably be wireless RF transceivers that are
`relatively small in size and transmit a relatively low power
`RF signal. As a result, in some applications, the transmission
`range of a given transceiver 205, 207 may be relatively
`limited. As will be appreciated from the description that
`follows, this relatively limited transmission range of the
`transceivers 205, 207 can be a desirable characteristic of the
`control system 200. Although the transceivers 205, 207 are
`depicted without user interfaces such as a keypad (not
`shown), the transceivers 205, 207 may be configured with
`user selectable buttons or an alphanumeric keypad (not
`shown). Often, the transceivers 205, 207 can be electrically
`interfaced with a sensor/actuator 222 such as a smoke
`detector, a thermostat, a security system, etc., where external
`buttons are not needed.
`It is significant to note that one or more specific types of
`RF transceivers may be used with the present invention. For
`example, one RF transceiver that may be used is the
`TRlOOO, manufactured by RF Monolithics, Inc. The 60
`TRlOOO hybrid transceiver is well suited for short range,
`wireless data applications where robust operation, small
`size, low power consumption, and low-cost are desired. All
`critical RF functions may be performed within a single
`hybrid semi-conductor chip, simplifying circuit design and 65
`accelerating the design-in process. The receiver section of
`the TRlOOO is sensitive and stable. A wide dynamic range

`system such as that illustrated in FIG. 2 may be employed
`to monitor and record utility usage by residential and
`industrial customers, to transfer vehicle diagnostics from an
`automobile via a RF transceiver integrated with the vehicle
`diagnostics bus to a local transceiver that further transmits 5
`the vehicle information through a local gateway onto a
`WAN, to monitor and control an irrigation system, to
`automate a parking facility, etc. Further information regard(cid:173)
`ing these individual applications can be found in the com(cid:173)
`monly assigned U. S. utility patent application entitled,
`"System and Method for Monitoring and Controlling Resi(cid:173)
`dential Devices," issued Ser. No. 09/704,150.
`The integrated transceivers 212, 214, 215, 222, and 224
`may have substantially identical construction (particularly
`with regard to their internal electronics), which provides a 15
`cost-effective implementation at the system level.
`Alternatively, the transceivers (integrated or stand-alone)
`can differ as known to one of ordinary skill in the art as
`necessitated by individual design constraints. Furthermore, a
`plurality of stand-alone transceivers 211, 213, 215, and 221, 20
`which may be identical, may be disposed in such a way that
`adequate RF coverage is provided. Preferably, the stand(cid:173)
`alone transceivers 211, 213, 215, and 221 may be dispersed
`sufficient that only one stand-alone transceiver will pick up
`a transmission from a given integrated transceiver 212, 214, 25
`216, 222, and 224 (due in part to the low power transmission
`typically emitted by each transmitter).
`However, in certain instances, two, or even more, stand(cid:173)
`alone transceivers may pick up a single transmission. Thus,
`the local gateways 210 and 220 may receive multiple
`versions of the same data transmission from an integrated
`transceiver but from different stand-alone transceivers. The
`local gateways 210 and 220 may utilize this information to
`triangulate or otherwise more particularly assess the location
`from which the common data transmission is originating.
`Due to the transmitting device identifier incorporated within
`the preferred protocol in the transmitted signal, duplicative
`transmissions (e.g., transmissions duplicated to more than
`one gateway or to the same gateway) may be ignored or
`otherwise appropriately handled.
`The advantage of integrating a transceiver, as opposed to
`a one-way transmitter, with the sensor is the transceiver's
`ability to receive incoming control signals and to transmit
`data signals upon demand. Significantly, the local gateways
`210 and 220 may communicate with all system transceivers.
`Since the local gateways 210 and 220 are permanently
`integrated with the WAN 230, the server 260 communica(cid:173)
`tively coupled with the WAN 230 can host application
`specific software. Further, the data monitoring and control
`devices of the present invention are movable as necessary 50
`given that they remain within signal range of a stand-alone
`transceiver 211, 213, 215, or 221 that subsequently is within
`signal range of a local gateway 210, 220 interconnected
`through one or more networks to server 260. As such, small
`application specific transmitters compatible with control 55
`system 200 can be worn or carried about one's person. It will
`be appreciated that a person so equipped may be in com(cid:173)
`munication with any device communicatively coupled with
`the WAN 230.
`In one embodiment, the server 260 collects, formats, and
`stores client specific data from each of the integrated trans(cid:173)
`ceivers 212, 214, 216, 222, and 224 for later retrieval or
`access from the workstation 250 or the laptop 240. In this
`regard, the workstation 250 or the laptop 240 can be used to
`access the stored information through a Web browser in a 65
`manner that is well known in the art. In another embodiment,
`the server 260 may perform the additional functions of
`
`6
`hosting application specific control system functions and
`replacing the local controller by generating required control
`signals for appropriate distribution via the WAN 230 and the
`local gateways 210, 220 to the system actuators. In a third
`embodiment, clients may elect for proprietary reasons to
`host any control applications on their own WAN connected
`workstation. In this regard, the database 270 and the server
`260 may act solely as a data collection and reporting device
`with the client workstation 250 generating control signals
`for the system. Further information can be found in the
`commonly assigned U.S. utility patent application entitled,
`"System and Method for Monitoring and Controlling Resi(cid:173)
`dential Devices," issued Ser. No. 09/704,150.
`Reference is now made to FIG. 3, which is a block
`diagram illustrating certain functional blocks of a trans(cid:173)
`ceiver 340 that may be integrated with sensor 310. For
`example, sensor 310 in its simplest form could be a two-state
`device such as a smoke alarm. Alternatively, the sensor 310
`may output a continuous range of values to the data interface
`321 such as a thermometer. If the signal output from the
`sensor 310 is an analog signal, the data interface 321 may
`include an analog-to-digital converter (not shown) to con(cid:173)
`vert signals output to the transceiver 340. Alternatively, a
`digital interface (communicating digital signals) may exist
`between the data interface 321 and each sensor 310.
`In FIG. 3, the sensor 310 may be communicatively
`coupled with the RF transceiver 340. The RF transceiver 340
`may comprise a RF transceiver controller 328, a data inter(cid:173)
`face 321, a data controller 324, a transceiver identificatier
`30 326, and an antenna 328. As is shown in FIG. 3, a data signal
`forwarded from the sensor 310 may be received at an input
`port of the data interface 321. The data interface 321 may be
`configured to receive the data signal. In those situations
`where the data interface has received an analog data signal,
`35 the data interface 321 may be configured to convert the
`analog signal into a digital signal before forwarding a digital
`representation of the data signal to the data controller 324.
`In accordance with a preferred embodiment, each trans-
`40 ceiver 324 may be configured with a unique transceiver
`identification 326 that uniquely identifies the RF transceiver
`340. The transceiver identification 326 may be
`programmable, and implemented in the form of, for
`example, an EPROM. Alternatively, the transceiver identi-
`45 fication 326 may be set/configured through a series of dual
`inline package (DIP) switches. Additional implementations
`of the transceiver identification 326, whereby the number
`may be set/configured as desired, may be implemented
`consistent with the broad concepts of the present invention.
`The unique transceiver identification 326 coupled with a
`function code for a sensor "on" condition is formatted by
`data controller 324 for transformation into the RF signal 330
`by RF transmitter 328 and transmission via antenna 323.
`While the unique transceiver address can be varied within
`the scope of the invention, it preferably can be a six-byte
`address. The length of the address can be varied as necessary
`given individual design constraints. In this way, data packet
`330 communicated from transceiver 340 will readily distin(cid:173)
`guish from similar signals generated by other transceivers in
`60 the system.
`Of course, additional and/or alternative configurations
`may also be provided by a similarly configured transceiver.
`For example, a similar configuration may be provided for a
`transceiver that is integrated into, for example, a carbon
`monoxide detector, a door position sensor, etc. Alternatively,
`system parameters that vary across a range of values may be
`transmitted by transceiver 340 as long as data interface 321

`and data controller 324 are configured to apply a specific
`code that is consistent with the input from sensor 310. As
`long as the code was understood by the server 260 or
`workstation 250, the target parameter could be monitored
`with the present invention.
`Reference is now made to FIG. 4. Alternatively, the sensor
`400 may be communicatively coupled with the RF trans(cid:173)
`mitter 410. The RF transmitter 410 may comprise a trans(cid:173)
`mitter controller 415, a data interface 420, a data controller
`425, a transmitter identification 430, and an antenna 440. 10
`The data signal forwarded from the sensor 400 may be
`received at an input port of the data interface 420. The data
`interface 420 may be configured to receive the data signal.
`In those situations where the data interface has received an
`analog data signal, the data interface 420 may be configured 15
`to convert the analog signal into a digital signal before
`forwarding a digital representation of the data signal to the
`data controller 425.
`Each transmitter/transceiver may be configured with a
`unique transmitter identification 430 that uniquely identifies
`the RF transmitter 410. The transmitter identification num(cid:173)
`ber 430a may be programmable, and implemented in the
`form of, for example, an EPROM. Alternatively, the trans(cid:173)
`mitter identification 430 may be set/configured through a
`series of dual inline package (DIP) switches. Additional
`implementations of the transmitter identification 430,
`whereby the identification may be set/configured as desired,
`may be implemented consistent with the broad concepts of
`the present invention.
`The data controller 425 may be configured to receive both 30
`a data signal from the data interface 420 and the transmitter
`identification 430. The data controller 425 may be config(cid:173)
`ured to format (e.g., concatenate) both data portions into a
`composite information signal. The composite information
`signal may be forwarded to the transmitter controller 415 35
`which then transmits the encoded RF signal from the sensor
`400 via a packet message protocol system. It will be
`appreciated that the transmitter controller 415 may convert
`information from digital electronic form into a format,
`frequency, and voltage level suitable for transmission from 40
`antenna 440. The transmitter identification 430 is set for a
`given transmitter 410. When received by the application
`server 260 (FIG. 2), the transmitter identification 430 may
`be used to access a look-up table that identifies, for example,
`the location, the system, and the particular parameter
`assigned to that particular transmitter. Additional informa(cid:173)
`tion about the related system may also be provided within
`the lookup table, with particular functional codes associated
`with a corresponding condition or parameter, such as but not
`limited to, an appliance operating cycle, a power on/off
`status, a temperature, a position, and/or any other informa(cid:173)
`tion that may be deemed appropriate or useful under the
`circumstances or implementation of the particular system.
`FIG. 5 sets forth a block diagram of the transceiver 500
`that is integrated with a sensor 510 and an actuator 520.
`Here, the data interface 525 is shown with a single input
`from the sensor 510. It is easy to envision a system that may
`include multiple sensor inputs. The RF transceiver 500 may
`comprise a transceiver controller 530, a data interface 525,
`a data controller 535, a transceiver identification 540, and an
`antenna 550. The data signal forwarded from the sensor 510
`may be received at an input/output port of the data interface
`525. The data interface 525 may be configured to receive the
`data signal and transmit a command signal. In those situa(cid:173)
`tions where the data interface 525 has received an analog
`data signal, the data interface 525 may be configured to
`convert the analog signal into a digital signal before for-
`
`8
`warding a digital representation of the data signal to the data
`controller 525. Similarly, when the data controller 535
`forwards a digital representation of a command signal, the
`data interface 525 may be configured to translate the digital
`5 command signal into an analog voltage suitable to drive the
`actuator 520.
`In accordance with a preferred embodiment, each RF
`transceiver 500 may be configured with a unique transceiver
`identification 540, that uniquely identifies the RF transceiver
`500 The transceiver identification 540 may be set/configured
`as described above within the broad concepts of the present
`invention.
`The data controller 535 may be configured to receive both
`a data signal from the data interface 525 and the transceiver
`identification number 540. The data controller 535 may also
`receive one or more data signals from other RF communi(cid:173)
`cation devices. As previously described, the data controller
`535 may be configured to format (e.g., concatenate) both
`data signal portions originating at the RF transceiver 500
`20 into a composite information signal which may also include
`data information from other closely located RF communi(cid:173)
`cation devices. The composite information signal may be
`forwarded to a transceiver controller 530, which may be
`configured to transmit the encoded RF data signals via the
`25 packet messaging system. It will be appreciated that the
`transceiver controller 530 may convert information from
`digital electronic form into a format, frequency, and voltage
`level suitable for transmission from the antenna 550.
`By way of example, a common home heating and cooling
`system might be integrated with the present invention. The
`home heating system may include multiple data interface
`inputs from multiple sensors. A home thermostat control
`connected with the home heating system could be integrated
`with a sensor that reports the position of a manually adjusted
`temperature control (i.e., temperature set value) and a sensor
`integrated with a thermister to report an ambient tempera(cid:173)
`ture. The condition of related parameters can be sent to the
`data interface 525 as well as including the condition of the
`system on/off switch, the climate control mode selected (i e.,
`heat, fan, or AC), etc. In addition, depending upon the
`specific implementation, other system parameters may be
`provided to data interface 525 as well.
`The addition of the actuator 520 to the integrated trans-
`45 ceiver permits the data interface 525 to apply signals to the
`manual temperature control for the temperature set point, the
`climate control mode switch, and the system on/off switch.
`In this way, a remote workstation 250 or a laptop 240 with
`WAN access (see FIG. 2) could control a home heating
`50 system from a remote location.
`Again, each of these various input sources is routed to the
`data interface 525, which provides the information to the
`data controller 535. The data controller 535 may utilize a
`look up table to access unique function codes that are
`55 communicated in the data packet 560, along with a trans(cid:173)
`ceiver identification code 540, to the local gateway and
`further onto the WAN. In general, the operation of RF
`transceiver 500 will be similar to that described above.
`It will be appreciated by persons skilled in the art that the
`60 various RF communication devices illustrated and described
`may
