`
`ABSTRACT
`[57]
`An electronic communication system monitor in one
`embodiment has sensors for sensing electrical and envi-
`ronmental conditions for communication system ele-
`ments. Control relays connect the elements to a pro-
`grammable controller. The programmable controller
`has a keyboard, display, printer and modem for remote
`communication of information; especially alarms pro-
`viding notice of operating conditions outside acceptable
`parameters. A second embodiment provides a logic
`circuit connected to selected sensors which determines
`when a combination of conditions exist to cause alarm
`and automatically activates a remedial device to allevi-
`ate a potential problem. The central processor also has:
`a message synthesizer and a connector for communicat-
`ing a message using dual—tone multifunction coded sig-
`nals or digitized voice signals to maintenance, emer-
`gency and security personnel or remote computers as
`appropriate; a memory for accumulating information
`and report preparation instructions for preparing re-
`ports of current alarms, alarm history, current status,
`relay status, channel monitor, and channel on time re-
`ports; and instructions for set-up. Manual or automatic
`operation is provided.

`
`COMPUTER-CONTROLLED ELECTRONIC
`SYSTEM MONITOR
`
`4,964,065
`
`This application is a continuation-in-part of US. pa-
`tent applicaiotn Ser. No. 025,216, filed Mar. 12, 1987,
`now US. Pat. No. 4,823,280, issued 4/ 18/89 for a Com-
`puter-Controlled Electronic System Monitor.
`BACKGROUND OF THE INVENTION
`
`This invention relates to electronic monitoring sys-
`tems and more particularly to a computer-controlled
`monitoring system for monitoring continuously and
`accurately the operation of communication systems.
`Electronic monitors of various degrees of complexity
`are known. They range from very simple power moni-
`tors, which measure power at a specific location near
`the transmitter, circular, cavity, N-way junction or
`antenna, to more versatile models which provide re-
`mote readout at an off-site panel that accepts and/or
`delivers information pertaining to power level and volt-
`age standing wave ratio (VSWR). In addition, some
`units are known to include remote communication of
`alarms, corresponding on/off power conditions, and
`local environment conditions such as,
`temperature,
`humidity, intrusion and fire.
`The problems with the known monitoring devices
`include their inability to generate and communicate
`actual measurements, to permit the programming of
`upper and lower operating limits, and to adapt to spe-
`cific operator needs such as calculating specific inser-
`tion loss characteristics across filters and cavities.
`A major advantage of the monitor of the present
`invention over known monitors is the provision of a
`computer-controlled, expandable electronic monitoring
`system. The system of the present invention accurately
`and continuously monitors electronic systems, pro-
`grams their operating parameters, meets various user
`needs, and tunes or retunes any tunable components
`without degrading overall performance of the system
`being monitored. These features enable the monitor to
`detect “soft” failures of the systems being monitored.
`Soft failures are the result of a slowly degrading system
`component, such as a corroding connector or a gradual
`shift in a cavity’s resonant frequency. With properly set
`alarm limits, the monitoring system uncovers and com-
`municates a transmit problem when performance drops
`below tolerable limits.
`
`SUMMARY OF THE INVENTION-7
`
`Accordingly, it is an object of the present invention
`to provide an improved electronic system monitor to
`give accurate information continuously from which
`“soft” failures can be detected and repaired prior to
`actual system failure, thereby reducing system down-
`time and maintenance and repair costs.
`Another object of this invention is to provide an
`electronic system monitor operable in a centralized
`control center for monitoring one or more electronic
`systems remotely located with respect to the system
`center.
`
`Still another object of the invention is to provide a
`monitor capable of simultaneous operation with an elec-
`tronic system without interrupting or degrading the
`electronic system operation.
`Yet another object of the invention is to provide a
`monitor having multiple alarm inputs and automatic
`remote or local alarm reporting.

`A further object of the invention is to provide a monia
`tor capable of measuring the operational outputs of a
`plurality of electronic systems.
`Still a further object of the invention is to provide a
`monitor having component tuning aid capability.
`Still yet a further object of the invention is to provide
`a monitor capable of monitoring selected conditions'and
`in response to the conditions activating a corrective
`device.
`
`An additional object of the invention is to provide a
`monitor with the capability of activating various com-
`munication modes for automatically notifying selected
`personnel of problems existing in the monitored system.
`Still another object of the invention is to provide a
`monitor system whose size is adjustable to meet existing
`monitoring requirements.
`Yet another additional object of the invention is to
`provide a monitor adapted for use with a portable key-
`board/display device.
`Briefly stated, the electronic system monitor appara-
`tus of a first embodiment of the present invention in-
`cludes a compact, computer-controlled, expandable
`monitor system having remote sensors for accurately
`measuring the actual power-related performance of a
`plurality of components of one or more electronic sys-
`tems and their local environment conditions. A decision
`maker is connected to some or all of the sensors and
`compares the measured power-related outputs of the
`sensors to normal operating limits for determining dete-
`riorating components. The decision maker activates an
`appropriate alarm and reports any abnormal component
`or environmental conditions to a central or remote
`station either automatically or upon command. At the
`station, the report is displayed or printed or both. The
`decision maker also provides information for use in
`tuning or retuning tunable components.
`In a second embodiment, the decision maker includes
`a logic circuit for determining the existence of a plural-
`ity of operation conditions for elements producing a
`single function and when found to exist automatically
`activating a remedial element for alleviating a potential
`problem. The decision maker or control processing unit
`also includes a message synthesizer including a voice
`synthesizer for producing messages and a communica-
`tion connector for communicating the message to se-
`lected maintenance, emergency, and security personnel,
`and remote computers. In addition to reporting current
`alarms, the central processing unit stores information
`and prepares alarm history, current status, relay status,
`channel monitor and channel on time reports. The cen-
`tral processor also provides for manual operation and
`prompts for guiding manual operation and initial setup
`of the system. The central processing unit is adapted for
`expansion using master and slave units, and for connect-
`ing a portable display/keyboard. Thus, the portable
`display/keyboard may be carried for use with master
`units at different sites.

`and a transmitter 28 serving a plurality of channels. The
`bidirectional power sensor 26 is connected by leads 30
`and 32 to the programmable controller 22.
`A plurality of local alarm input circuits 34 are con-
`nected to the programmable controller for inputting
`information indicative of various operating failures and
`adverse local environmental conditions at the antenna
`sites. Also, a plurality of local alarm output circuits 36
`are connected to the programmable controller 22.
`A printer 38 is connected by bus 40 to the program-
`mable controller 22. Upon command from the program-
`mable computer, the printer prints selected information
`from the programmable computer.

`A terminal 42 that provides two-way communication
`to the programmable controller completes the com-
`bined system. The terminal is connected by a telephone
`connection 44 to a MODEM 46. The MODEM 46 is
`connected by lead 48 to the programmable controller.
`The in-line antenna bidirectional sensor 14 inputs
`analog (dc) signals indicative of the output reflected
`power (OPR) from the antennas for a particular channel
`through lead 18 to the programmable controller 22 for
`display in watts. The sensor 14 also inputs analog signals
`indicative of the output forward power (OPF) of the
`combiner 16 for a given antenna through lead 20 to the
`programmable controller 22 for display in watts.
`In addition, the in-line combiner bidirectional sensor
`26 inputs analog signals indicative of the input forward
`power (IPF) to the combiner 16 for a particular channel
`on lead 30 to the programmable controller for display in
`watts. Further, the sensor 26 inputs analog signals indic-
`ative of the input reflected power from the combiner 16
`for a particular channel through lead 32 to the program-
`mable controller for display in watts. This sensor ar-
`rangement will be discussed further in connection with
`a second arrangement hereinafter.
`The local alarm system circuits 34 include sensors to
`facilitate flexible and diverse local alarm needs such as,
`for example,
`intrusion,
`temperature, and flooding in
`addition to the outside-the-norm measurements of the
`antenna, combiner, and transmitter.
`The programmable controller 22 (FIG. 2) includes a
`computer 50. A suitable computer is an INTEL 8085
`microprocessor sold by INTEL Corporation. An elec-
`trically programmable read only memory (EPROM) 52
`and a random access memory (RAM) 54 are connected
`by bus 56 to the microprocessor 50. The EPROM stores
`instructions to adapt the system to user needs, and the
`RAM stores the system acquired data or information by
`date and time provided by the microprocessor clock.
`The RAM 54 is protected from a power down situation
`by a battery 58 (Lithium battery).
`A keyboard 60 is used to enter operation parameters
`and to call up information for display on a display 62.
`The display 62 is, for example, a 16 digit liquid crystal
`display connected to the microproccessor.
`An analog to digital converter (ADC) 64 having a
`plurality of channels for digitizing the incoming analog
`(dc) data signals is connected by leads 66 to the micro-
`processor 50.
`The microprocessor 50, EPROM 52, RAM 54, and
`ADC 64 and interface circuitry are preferably comple-
`mentary metal oxide semiconductor (MOS) integrated
`circuit (IC) devices because they are readily available,
`have less power consumption and dissipation, and ex-
`hibit high impedance characteristics. Thus, a small Lith-
`ium battery will hold the RAM for about three years,
`and the high impedance of CMOS devices allow inter-
`facing without disruption of the system.
`The microprocessor 50 is connected to a power sup-
`ply 68. The power supply provides a +5 volt and a
`:i:/-12 volt source of power for the system from either
`an ac or dc power source. The power supply is con-
`nected to power-fail circuit 70. The power-fail circuit is
`connected by lead 72 to the microprocessor and RAM
`to signal when power failure is imminent to initiate a
`routing to save all volatile data. After power restora-
`tion, a routine is initiated to restore the data and restart
`computer operation.
`The local alarm signals are received in a register 74
`and multiplexed into the microprocessor 50 for process-

`ing. The microprocessor 50 is connected to a solid state
`relay device 76 for outputting alarm signals to antenna,
`transmitter, combiner, or local alarm action circuits.
`The programmable controller 22 includes a housing
`78 (FIG. 3) for housing the circuitry of the programma-
`ble controller, a front panel 80, and a connector panel
`82 (FIG. 4).
`The programmable panel front panel 80 includes a
`switch 84 having an OFF position between ac and dc
`power positions. A plurality of status lights (LEDs) are
`connected to the microprocessor as action circuits iridi-
`cating the operational status of the system as follows.
`Lights 86, 88, and 90 on a first side of the panel are
`turned on to indicate, respectively, that the monitor is
`operating on home power, the Lithium battery for the
`data storage RAM needs replacement, and a local alarm
`exists. While, lights 92, 94, and 96 on a second or oppos-
`ing side are turned on to indicate, respectively, that the
`combiner insertion loss is excessive, the analog data is 20
`being input to the processor, and the data is being trans-
`ferred remotely. Indicator lights 86, 94, and 96 being of
`an informative nature are green lights; while lights 88,
`90, and 92 being trouble indicating lights are red lights.
`Antenna status lights 98 and 100 are turned on and 25
`off, respectively, to indicate whether the plurality of
`antennas are operating within prescribed parameters or
`an antenna alarm exists. The former is green and the
`later is red.
