`Autonomous Radlo Telenetry
`
`BACKGROIJND OF THE INVE}IIION
`The present invention is directed toward the field of radio
`telemeEry. In part.icular, an improwed radio modem is disci-osed
`for use in an autonomous radl-o telemetry system, the radio modem
`including a progranuned mode of operaLion that converts the
`general purpose radio modem inEo a special purpose radio
`telemetry computer system, thereby eliminating the need for a
`separale lelemetry computer as Eaugh! by the prior art.
`In a E.elemeE.r], syst,em analog or digital metering data, such
`as an analog measuremenc of a process variabLe, or the digital
`sEate of a swiEch, is captured aE a remoce location by a
`tefemetry computer and is then transmiEted Eo a central computer
`facility via a Lelecommunication device. In radio-telemetry the
`EeLecomunication dewice is a radio modem that lransmits the
`metering daLa bet.ween Lhe celemetry computer and tshe central
`compuLer. faciLity via radio frequency waves, thus eliminating the
`need for land-line wiring, guch as a telephone line.
`Applications for telemetry systems range from simple awitch
`aclualion and monit,oring systems E.o complex process line
`compuEers. For example, Ehe following systems could be
`implemented wiEh an autonomous telemetry system: (j-) monitoring a
`door switch and sending a signal when the door is opened; (ii)
`counting the number of items put into a drop box, by noting the
`number of t.j-mes t.he drop box door is opened, and periodically

`
`reporling lhe nurdter of items in t.he box; (iii) acguiring and
`recording the temperature and current. draw of a motor and
`transmitEing recently recorded data nhen the temperalure of the
`motor exceeds a predet.ermined level ; or (iv) remotely turning
`on/ off lights, or an alarm system; etc. The applicat.ions of such
`telemeiry systems are numert6us, and the previous examples are
`merely presenLed t.o assist in underslanding the broad scope of
`t.he possible applicaCions for such t.elemet,ry systems.
`Prior art radio teLemetry systems include a separate
`telemetry computser and radio modem at. a remote l_ocat.ion for
`capturing and transmi-Eting data to the centraf computer facir-'ty.
`fmplementors of these types of systems incorporat.e an embedded
`programmed microprocessor as the lelemeE.ry compuEer, and
`interface the telemet.ry computer to input/output devices such as
`a complex analog to digital converter board, or a simple switch.
`The 'telemet.ry comput.er is also connected to Ehe radio modem.
`generally wia a serial interface. The E.efemetry computer
`controls and monitors the inEerface to the input/output devices
`and communicates with the central computer sysEem using the radj_o
`modem. In these tl4)es of prior art telemecry sysE.ems, the radio
`modem is simply a module in the overall remot.e tej.emeEry sub_
`system that is required for communication purposes,
`These previous ter-emetry systems suffer from a number of
`disadvantages, parEicu]ar1y when the E.elemerry sysE.em is used in
`a reLatively simple applicacion, such as rthe monitoring of a
`sr,/it.ch, or t.he acquisi.tion of a single process variabl_e. The
`
`10
`
`i! !l- 5

`
`

`
`disadvantages of these prior art syst.ems incLude high cosC, high
`power consumption, large physical size, and complex integration.
`These disadvant.ages arise because the previous telemetrv
`systems do not. appreciate or utiLize the power of the
`5 microprocessor or microcontroller that is buir-t into present day
`radio modems. rnstead. lhese systems use t.he radio device solely
`for communication. and employ a separaLe embedded microprocessor,
`che telemetry computer, "" fn. inE,erface to the inpuc/output
`devices. These aystems waste the processing power available in
`10 Ehe radio modem and therefore resurt in increased cosc, power,
`and size of the t.elemet.ry device.
`*i
`Therefore, there remains a need for a simple, Low cost.,
`lj
`sma11, and easy to integrate telemeLry device for use in an
`tI
`autonomous radio telemetry system. There remains a further need
`?
`*45
`for such a ter-emetry device that does not waste
`processr-ng
`'he
`:,-*
`power inherent. in the radio modem, but instead is configured to
`1j
`maximize the processing power of the microprocesso' cont.ained in
`r,i
`the radio.
`E
`In addition, there remains a need for an autonomous
`telemecry system thaf includes at least one of the above
`mentioned telemetry dewices in communicat.ion with a centraL
`comput,er system t.hat is capable of sending command.s co che
`telemecry devices, and receiving data transmissions from t.he
`ter-emetry devices indicating the state of input/outpuE. devices at
`the remot.e l0cacion.

`
`SUMMARY OF THE INVEN"TON
`The presenE invention ovexcomes the problems noted above and
`salisfies t.he needs in this field for a fow cost, 1ow power,
`simple, easy Eo int.egrat.e telemetry device for use in a wireless
`t.elemetry system. According to the presenE invention, a
`lelemetry device is prowid.ed that includes a radio modem havrnq a
`programmable microprocessoE4, wherein the radio has been
`configured Eo operate in a mode which converts Lhe general
`purpose radio device inLo a special purpose radio teLem e1ry<_ ltdL)
`compuEer. By recognj-zing that much of t.he processing power of
`the radio modem is waated in prior art telemetry systems, and by
`progranrning Ehe raqio modem such Chat it takes Ehe place of the
`prior art. t.elemetry computer, the present invention provides a
`solution to the problems associated wiEh the prior arE systems.
`The present inwenE.ion provides a teLemetry device that
`includes a radio modem having an internaL mj. croprocessor,
`reprogrammable teLemet.ry program storage, a radio Jr"rr"""irr..,
`and a serial interface. In lhe present invention, lhe seriaf
`lnterface. which is normar-ly used to conmrunicate vrith another
`compuLer system. is reconfigured by the microprocessor operating
`Ehe telemetry program to be a general input/output inE.erface for
`connecE.ing input/output devices (e.g. switches, TTIJ 1ogic, I2C
`bus dewj.ces) directly tso the radio modem. By connecting the
`input/output devices direccly to the modem, the present inventl0n
`provides a Eelemetry dewice which does not requj.re a separat.e
`telemetry computer. The inLernal radio mddem microprocessor
`
`-4-
`
`20
`
`4a
`
`Petitioner Cypress Semiconductor Corp. - Ex. CSC 1002, p. 11
`
`

`
`takes the place of lhe telemetry computer, performing dat.a
`acquisiE.ion, I/O control, as well as its prior function of
`contror'r-ing data transmission over the radio modem transceiver.
`Thus, the presenE i"nvention provides a new tefemeEry device which
`is smaller, Lower cost., consumes less power, and is easier to
`integrace lhan Ehe prevl,ou>. telemetry devtces.
`rn addition to reconfiguring the seriar. port to interface
`with the input,/output devices, the present invenlion includes the
`provision of a novel reprogrammable state machine architecture
`wiE.hin the radio modem that provides flexible operat.ion and
`programrnabillty of. lhe device. This sEate machine architecLure. <--.
`incruding a numlf,er of separa'ely programmable state machines, is
`construct.ed in software, but could, be incorporat.ed preferabty in
`hardware.
`The prograrftnable stat.e machines are used as decision making
`appqratuses for the telemet.ry device, These sEat.e machines can
`be reprogrammed or debugged remotely from the central computer
`syst.em since the radio modem incfudes a reprogranunable memory. qz_
`''nus ' the operation of the remote telemetry device can be alLered
`or tested without having Lo remove the devl-ce from a remote
`location or without having t.o send a technician to the remoEe
`site. This aspect of the invenEion is particularly advantageous
`lvhere the teLemetry device is located in a hazardous area.
`There are many advantages of the present j.nvention. First,
`by recognizing and util.izing Lhe inherentr processing power of the
`radio device, the present invention provides a simple, l or4r power

`
`telemetry device that can be easily integrat.ed with exj.sting
`sysEems, and existing inputr/output devices. Anog,her advantage of
`the present invent.ion is that by eliminating the need for a
`separate telemetry comput.er, the total cost of the sysE.em is
`reduced sj-nce there are fewer components, smaller devel_opment
`costs, and less time required to config-ure and program the
`/;
`SYAE.em.
`Another advant.age of the present invention is E,hat it
`provides for a nufiber of softr,rare s.ate machines programmed into
`the radio modem, the staEe machj.nes being easily and fLexibLy
`reprograruned in order to mee! a variety of needs for radio
`es4snLeL,.t .
`.,.hese \state machines provide an ef f icient, yec
`|alamafl.a'
`simple, decision-making architecture for the radi-o modem.
`YeE another advantage of the present invention is t.hat the
`+1l5 radio modem telemetry program is reconfigurable from a remoE.e
`=
`:.*_=
`locaE,ion over the radio interface. This provides f or remoEe
`'aj

`=,
`having to either remove the telemetry dewice or send a technician

`-
`to the remote locaE.ion. In addition, passlrord proLection is
`20 provided so that onLy authorized personnel can change the
`operation of t.he telemetry dewice.
`As will be appreciated, the invention is capable of other
`and different embodiments, and its severar. details are capable of
`modificacions in various respect, al-I withouE. departing from the
`invention. Accordingly, the drawings and description of the

`rr.vw to the drawings, Figure 1 and 2 set forth
`prior art' telemetry syst.ems. Figure 1 shows t.he t,raditj-onal
`configuration of a prior art telemetry device, including separaE.e
`modem 24 and telemetry computer 10, the telemetry computer 10
`including RAM 12 and ROM 14, t.he RAM 12 being used for program
`operation and general purp;e memory, and the ROM 14 being used
`for program storage. Input/Output. devices L6, 18, and 20 are
`connected to the telemetry comput.er 10, which controls and
`manipul-ates the r/o devices, and Eransmits information via modem
`24 over a standard phone connection 26 to a centraL computer
`system (not shown). The connect.ion between E.he telemeEry
`computer 10 and modem 24 is typically a serial port connection,
`such as a st.andard RS-232 connecEion, and the protocol used is
`generally the AT-modem protocol lhat is sCandard with most
`gene,ral purpose tel-ephone modems
`Figure 2 sets forth a prior art radio E.eLemetry system,
`including t.he same element.s as Figure 1, including separate
`cel-emetry computer 30 and t.efecommunicat ions device (radio modem)
`44, RAM 32 and ROM 34 for use by the Eelemetry computer, several

`modem (not sho$rn) wiE.h an antenna 4g for receiving and
`transmilling information to associat.ed radio teLemetry devices
`associated with the centra] computer system.
`The present. invent,ion is applicable to any kind of radio
`modem and any t).pe of radio frequency data network, however for
`the purpose of setting for.bfi a prbferred emlcodiment of the
`invention, the remaining drawings and detailed description wilt
`refer to a specific radio network, t.he Mobitex network, and a
`particular radio modem. the RIM 900 Mobitex radio modem,
`manufactured by Research In Motion, 295 phillip Street, Wat.erloo,
`Ontario. Canada.
`There are many lypes of radio networks currenL.J.y in
`widespread use, such as Ardis, MobiE.ex, GSM, SMR, pCS, analog
`ce11ular, CDPD, etc, and each of these networks has associaled
`cypes of radj.o modems that are used t.o transmit and receive data
`over the network. For exampf e, for L.he Mobitex oJtror:.,
`Ericsson, MoEorola and Research In Motion manufacture radio
`modems.. Any of these devices could be used in conjunction with
`the present invent.ion.
`The Mobitex network is a packeEized RF data network that was
`developed by Eritel,/Ericsson in 1994 in Sweden, and has become an
`international dala communication atandard. The Mobitex network
`was first. established in North America in 19g9 and is now
`available in most major metropolitan areas throughout Canada and
`Ehe Unit.ed Scates. The Mobj.tex packet-gwitched network provides
`highly reliable two-way digit.al data transmission, including
`
`-J-

`
`

`
`error detection and correct.ion lo ensure the integrity of the
`data being sent and received.
`fn contrast to analog circuit switched systems, a packet_
`sr./itched net,work, such as Mobitex, breaks the dat,a into pieces
`cal-led "packetsn. rn Mobitex each individual packet is called an
`MPAK. Each MPAK includes 5l-2 bytes of informat.ion. a time sEamp,
`and the network address of the Bender and receiver of lhe packet.
`In this way, each Mobitex pd6ket can be successfully routed or
`ret.urned t.o the correct network user.
`The Mobitex network conforms to Ehe International
`Organization for St.andardization (ISO) model for dat.a
`communications, termed t,he Open Systems IncerconnecEion (OSI)
`model . The OSI model is an open architecture that divides data
`communication into several layers, each of which buirds upon and
`masks t.he complexiEy of the layers beLow it. The sewen layers of
`t.he OSI model are, from lowest to highest: physical layer, daE,a-
`. link-1ayer, net.work 1ayer, transport 1ayer, session 1ayer,
`presi:nEation tayer, and application 1ayer. The three layers
`actually involved in mowing dat.a from one computer to another are
`the data-l_ink 1ayer, the network ]ayer, and the transport 1ayer.
`In Mobitex, L.he data-l-ink layer includes the MASC and ROSI
`prolocols. The MASC protocol (Mobitex Asynchronous protocol)
`provides the machine incerface that alLows packets t,o be
`transferred over the data link created by MobiEex. fhe ROST
`proLocoL (Radio open syst.em rnlerface) is used by Ehe radio unit
`to communi-cate vrith the base station. The network tayer in

`
`Mobitex is the MPAK described above, and t.he transport layer uses
`MfP/1 (Mobit.ex Transport, Protocol 1), which is a tesEed and
`standardized transport. protocol that ensurea data packets are

`Referring back t.o Fi$rre 2 r E}l.e prior art radio telemetry
`system is shown, including -separate radio modem 44 and telemec.ry
`computer 30. Radio Modem 44 could be, for exampfe, a RIM 900
`MASC radio modem, or coul-d be an Ericsson Mobidem-AT. Depending
`on t,he type of modem, seriaL inEerface 42 will be transferring
`eiEher AT- t)rpe ionnnands (Mobidem-AT) or MASC comnands (RIM 900)
`In bolh cases, as is tshe case for the prior art system of Figure
`1, the telecommunicat ions device, modem or radio modem, is only
`performing data coflEnunications functions. All interfaclng and
`control of the input/output devices 36-40 is carried out by the
`tselemetry compuLer 30 operating the program stored in ROM 34.
`This is the primary disadvantage of such prior art telemeLry
`sysEems.
`Figure 3 sets forth a basic block diagram of an autonomous
`radio telemetry system according to the present invention. By
`recognizing that modern radio modems / such as the RIM 900,
`include powerful microprocessors or microconEroLL ers Ehat are
`mostly idle during periods of Lime where no data transmission is
`occurring, the presen! invention solves Ehe problems of the prior
`art telemetry systems by prowiding a low cost, 1ow power, and
`t
`easy to integrate telemetry device.

`autonomous radio L.elemetry (AIIT) program that converts the
`olherwise general purpose radio modem into a special- purpose
`radio telemetry device. By providing che radio modem 60 wiE.h
`special computer programming (ART), the t.elemetry computer 3O of
`the prior art systems can be discarded and the l_nput,/output
`devices 66, 58, Z0 can be int,erfaced directly t,o tshe radio modem
`50. As will be describe.d in more detail below, the ART
`program
`reconfigures the seriaf port. of the radio modem from a
`Mobitex MASC protocol to a general purpose input./output
`sys tem
`t.hat supports TTIr 1ogic, simple switches, and an f2C bus. The
`ART program also incLudes a novel reprogranmable state machine
`architecture that is used for decision makj_ng by the telemetry
`dewice. In this manner, E.he radio modem becomes a
`more polrerful
`speciaL purpose E,el-emetry dewice E.hat incfudes most
`functionality and flexibility of the prior art system of figure 2
`at a fraction of the cost, power, size and complexiLy.
`Figure 4 sets forth a more detailed bLock diagram of an
`autonom6us radio telemetry system using the ART radio modem of
`the present invention. Radio modem 60 includes antenna 92, rad.io
`interface 88 including modulaE.ion and demodulation circuj.try,
`microprocessor 80, serial interface 90, RAM gz, and Flash EPROM
`86. The radio modem receives Mobitex data in the form of MpAKs
`from the cenlral computer 74 vla an asgociated anEenna 22.
`r-,ikewise, the radio modem can transmit MPAK data to Lhe centra]
`computer system 74 using antenna 92.

`The radio interface and modulalion demodulation circuitry gB
`includes standard radj_o componenEs, such as mixers,
`dov,mconverters, limiting filters, discrimination circuitry,
`modulat.ion circuir.ry, analog to digital and digital to analog
`converters, etc. This circuitry is used to receive an RF signat
`from the Mobitex netvrork, reduce the signal to a demodulation
`frequency, demodulaE.e baseband information from the signal , and
`then to convert the analog signal into a digital representaEion.
`Likewise, this circuitry c,akes a digital signal from che
`microprocessor converts the signal to an anaLog.represent.ation,
`modulates t.he basehand information wiE,h a carrier signal and
`upconverEs t.o a RF signal for t.ransmission.
`Microprocessor g0 is preferably an Intel 80C1gg
`microprocessor, buE. could aLterriacively be any other type of
`microproeessor or microcontrol l er. As described above, the
`microprocessor builds data MPAKE for rransmiesion ;ia radio 88
`over the Mobitex network. and receives MpAKs from the radio
`interface 88 and can take act.ion based on this received data.
`The microprocessor j_s connected to RAM 92, vrhj_ch is used as in
`the prior art for program operation and general purpose memory
`storagfe, and Flash ROM 86. The Flash ROM 96 is could be a Ftash
`EPROM, EEPROM, PAROM, or any ot.her t].pe of reprogramnable
`permanent. memory device.

`ART program that forms a part of the present invention. These
`latter t.wo programs provide for t$ro different modes of operation
`of the radio modem 60. when operating in the MASC mode, t.he
`radio modem operates like other standard Mobitex radio devices,
`with the serial port 90 being configured E,o connect to anot.her
`computer sysEem lhat communicates to the radio modem 60 using t.he
`MASC protocol . The second mode of operation, which will be
`degcribed in more detail UJo*, is the autonomous radio telemecry
`or ART mode. ART takes the ptace of the MAS C data_1ink layer
`(i.e. can send, receive and interpret the MpAKs), remaps the
`radio modem serial porE 9O to interface to the input/output
`/.^.... ^^- ^,
`aevaces 94, 96, gg and provides the software scat.e machine
`architecture for cbntrolling
`decisions of the microprocessor
`80.
`
`'he
`
`Microprocessor gO is al-so connect.ed Eo serial interface 90,
`which is preferably an RS-232 interface, but. could be any ot.her
`type of serial , paralIer, or other data corununicat.ion int.erface.
`The 14-pin RS-232 standard int.erface is mappeil for lhe two mod.es
`of operation, MASC, and ART. as shown in Figure 4. As seen in
`Lhe tabLe next. to the pins of the serial port, when t.he radio
`modem is operat.ing in MASC mode, E.he serial port is confj-gured !o
`transmit and receive serial data with another compuEer system
`that is using the radio modem sirnply as a communication element..
`But, when the radio is swit.ched into ART mode, the ART program
`causes t.he microprocessor gO to remap the serial porE so lhac
`there are four general purpose TTL., inputs, l"abelled Input 0 _

`
`rnput 3, four outputs, labelled output 0 - output
`data bus, with associated clock and data lines.
`The architecture of Ehe ART program wil1 be described rn
`more detaif, below, but as can be appreciated from Figure 4, by
`taking advantage of the inherenE. processlng power of the radio
`modem 60 and by prowiding t.he additionaf intelligence (ART)
`necessary Eo conver! the rqglio from a generaf purpose
`communications device into a special purpose telemetry compuE.er,
`an rmproved teLemet.ry device and sysLem can be consE,ructed which
`eliminates the need for a separate tel_emetry computer, and
`thereby provides a l_olrer cost, lower power. easier to integraEe
`radio telemetry sy€tem.
`Having described Lhe broad concept of E.he autonomous radio
`telemetry system of the present invention, attention is now
`Eurned to the decision-making architecture of the improved radio
`modem operaLing the ART telemetry program. It is t.o be
`undgrstood that the following detailed description of the ART
`system architecture is but one embodiment of a system design E.hat
`can be used with th€ ) present invent.ion, and Lhat many other
`designs could alternativel-y be implemented without departing from
`the spirit or scope of E.he invenlion.
