Description
IDENTIFICATION SYSTEM
THIS INVENTION relates to electronic tags. It also relates to a method of communicating data from an electronic tag, to an identification system, and to a receiver for receiving a transmission from the electronic tag.
According to the invention, there is provided an electronic tag which includes processor means programmed to provide a modulation control signal which includes unique identification data which at least identifies the tag; and transmitter circuitry connected to the processor means and to an antenna for transmission of the unique identification data, the transmitter circuitry being powered by the modulation control signal.
Preferably, the transmitter circuitry is exclusively powered by the modulation control signal of the processor means. Accordingly, the transmitter circuitry is not connected to another source of power but merely to ground and to the processor means. Thus, when the modulation signal is at 0 volts, the transmitter circuitry receives no power resulting in no transmission at all thereby enhancing the low power consumption characteristics of the electronic tag. There is thus no carrier wave and the output or identification signal is thus a pulsed wave switched between 0 volts and its maximum amplitude.

The transmitter circuitry may include passive components and a transistor defining oscillation circuitry directly driven by the processor means. The transistor in combination with the passive components may form an integral part of the transmitter circuitry which is powered up by the modulation signal.
The processor means may be configured to provide the modulation control signal with a first part followed by a second part.
The first part may include at least one high pulse of such a duration so as to provide sufficient power to the transmitter circuitry at least partially to stabilize it for transmission of the second part. The second part may include data defined in a plurality of pulses which are of a substantially lesser duration. The signal transmitted by the transmitter circuitry of the tag resembles a combination of an amplitude modulated signal and a pulse width modulated signal. The amplitude modulation of the transmitter under control of the processor means is typically between about 0 % and about 100%. Accordingly, the power consumed by the transmitter whilst data is not being transmitter is substantially reduced.
It is however to be appreciated that the transmitter circuitry may modulate the amplitude of the identification signal at any percentage between 0 % and 100 % thereby representing a plurality of values or levels and not merely two levels of "1 "s and "0"s.
The modulation control signal may include a plurality of high pulses that, in combination, provide an identification signal to a tag receiver for receiving a transmission from the electronic tag. The high pulses are typically about 60 microseconds in duration with a 50 % duty cycle. It is however to be appreciated that the duty cycle and/or the duration may differ in various embodiments of the invention.

The modulation control signal may include a plurality of high pulses that, in combination, provide an identification signal to a tag receiver for receiving a transmission from the electronic tag. The high pulses are typically about 60 microseconds in duration with a 50 % duty cycle. It is however to be appreciated that the duty cycle and/or the duration may differ in various embodiments of the invention.
Thus, the high part of the modulation signal may perform a dual function. Firstly, it may power up the transmitter circuitry between, preferably, a totally switched off or dormant state, to an operative state in which it has stabilized sufficiently to transmit the second part comprising a pulse train of pulses of a substantially shorter duration.
Secondly, the first part allows the receiver to distinguish a transmission from the tag from any other transmission e.g. an interference signal or the like from another source.
Each pulse of the second part of the modulation signal may include a start portion for identifying a start of a bit and a data portion for identifying a state of the bit of data. The duration of the data portion may selectively define a high and a low state of the bit under control of the processor means. The pulse width may be defined as the sum of the start and data portions.
The high state of the bit is typically defined by a shorter data portion during which the oscillator circuitry is switched off and the low state of the bit is defined by a longer data portion during which the oscillator circuitry is switched off.
The shorter pulse may be used to mark or identify the start of a bit after which the transmitter circuitry is switched off totally. The time interval or duration until the transmitter circuitry is switched on again defines the high or low state of the bit. The amount of power required to transmit a high bit and a low bit is substantially the same since power is only consumed to identify the start of a bit of data.

The time interval or duration until the transmitter circuitry is switched on again defines the high or low state of the bit. The amount of power required to transmit a high bit and a low bit is substantially the same since power is only consumed to identify the start of a bit of data.
The processor means is typically a micro-controller which includes an internal RC oscillator on which the modulation control signal is dependent and the micro-controller is arranged to enter a sleep mode between data transmissions thereby to reduce power consumption.
Accordingly, the transmitter circuitry, under control of the processor means may be arranged periodically to transmit the identification signal is bursts at a predetermined time interval, for example about 1 s.
Preferably, the identification signal has a duty cycle of about 50 %.
Data is typically transmitted in a digital fashion as a series of "1 "s and "0"s. Typically, a "0" is transmitted by a transmitter on time being about 10 microseconds followed by an off time of equal duration, and a "1 " is transmitted by the transmitter being on about 5 microseconds followed by an off time of equal duration so that the signal has a 50 % duty cycle. It is however to be appreciated that any two different transmission time intervals, controlled by the transmitter processor may be used to communicate a "1 " or a "0". Further, the duty cycle of the pulses may vary.
Further in accordance with the invention, there is provided an identification system which includes a plurality of electronic tags, each tag including processor means programmed to provide a modulation control signal which includes unique identification data which at least identifies the tag; and transmitter circuitry connected to the processor means and to an antenna for transmission of the unique identification data, the transmitter circuitry being substantially powered by the modulation control signal; and at least one electronic tag receiver configured to receive a transmission from the tag.
The transmitter circuitry of the electronic tag may be exclusively powered by the modulation control signal of the processor 5 means.
The transmitter circuitry may include passive components and a transistor directly driven by the processor means. The transistor in combination with the passive components may form an integral part of the transmitter circuitry which is powered up by the modulation control signal.
The processor means may be configured to provide the modulation control signal with a first part followed by a second part, the first part including at least one high pulse of such a duration so as to provide sufficient power to the transmitter circuitry at least partially to stabilize for transmission of the second part which includes data defined in a plurality of pulses which are of a substantially lesser duration.
The first part of the modulation control signal may include a plurality of high pulses that, in combination, provide an identification signal to signal detection means of the electronic tag receiver for receiving a transmission from the electronic tag.
Each pulse of the second part of the modulation signal may include a start portion for identifying a start of a bit and a data portion for identifying a state of the bit of data, the duration of the data portion selectively defining a high and a low state of the bit under control of the processor means.
The high bit may be defined by a shorter data portion during which the transmitter circuitry is switched off and the low bit is defined by a longer data portion during which the transmitter circuitry is switched off.
Still further in accordance with the invention, there is provided a method of communicating data from an electronic tag, the method including driving transmitter circuitry of the tag with a modulation control signal which substantially powers the transmitter circuitry.
Typically, the modulation control signal exclusively powers the transmitter circuitry.
The transmitter circuitry may include an oscillator which is arranged to oscillate at its fundamental frequency when data is being transmitted and stop oscillating when data is not transmitted.
Accordingly, the method may include selectively modulating a fundamental frequency of the oscillator when data is being transmitted and disabling the oscillator when data is not being transmitted.
The modulation control signal may include a first part followed by a second part, the first part including at least one high pulse of such a duration so as to provide sufficient power to the transmitter circuitry at least partially to stabilize it for transmission of the second part which includes data defined in a plurality of pulses which are of a substantially lesser duration.
The first part of the modulation control signal may include a plurality of high pulses that, in combination, provide an identification signal to a tag receiver for receiving a transmission from the electronic tag.
Each pulse of the second part of the modulation signal may include a start portion for identifying a start of a bit and a data portion for identifying a state of the bit of data, the duration of the data portion selectively defining a high and a low state of the bifi under control of the processor means.
The high bit may be defined by a shorter data portion during which the modulation control signal is switched off and the low bit may defined by a longer data portion during which the modulation control signal is switched off.
The processor means is preferably a micro-controller which includes an internal RC oscillator on which the modulation control signal is dependent and the micro-controller is arranged to enter a sleep mode between data transmissions thereby to reduce power consumption. The micro-controller may define a transmitter processor which is typically a PIC 12C509 or the like, which is programmed with appropriate software to execute the method of controlling the transmitter.
Still further in accordance with the invention, there is provided a receiver for receiving a transmission from one of a plurality of WO 00/52636 . PCT/IB00/00220 electronic tags, the transmission including a first part and a second part and the receiver including detection circuitry for detecting the first part and the second part of the transmission, the first part including at least one high pulse in response to which the receiver monitors reception of the second part which includes data defined in a plurality of pulses which are of a substantially lesser duration; and timing means for timing the duration of each of the pulses in the second part and selectively generating a high or a low output defining a bit dependent upon the duration of the pulse.
The receiver may include pulse width detection circuitry for decoding the identification signal.
The receiver may include receiver circuitry connected to an antenna for receiving the identification signal from at least one electronic tag;
demodulation circuitry connected to the receiver circuitry for demodulating the identification signal;
amplification circuitry connected to the demodulation circuitry via a capacitive link; and receiver processor circuitry connected to the amplification circuitry for processing the identification signal after demodulation thereof.
The receiver may include a repeater transmitter for re-transmitting the identification signal to a central control unit. Typically, each tag is attached to an item of value, e.g. a personal computer or other valuable item, located in a particular zone and a receiver monitors the transmission of identification signals in the zone. The central control unit may thus be in wireless communication with a plurality of zones each of which include a receiver monitoring associated tags located on valuable items or equipment in the zone.
The invention is now described, by way of example, with reference to the accompanying diagrammatic drawings.
In the drawings, Figure 1 shows a schematic circuit diagram of a electronic tag in accordance with the invention;
Figure 2 shows a schematic circuit diagram of a receiver, also in accordance with the invention;
Figure 3 shows a flow chart of a method of controlling transmission of data via the tag of Figure 1;
Figure 4 shows an example of a burst of data transmitted by the transmitter; and Figure 5 shows a flow chart of a method of decoding data by the receiver of Figure 2.
Referring to the drawings, an identification system, in accordance with the invention, is provided which includes a plurality of transmitters which are in the form of electronic tags 10 (also in accordance with the invention and only one of which is shown in the drawings), each of which is associated with at least one receiver 12 (see Figure 2). Typically, valuable items or equipment to be monitored in a selected zone, e.g. computers in a particular office area, are each fitted with a tag 10 and the receiver 12 is located in the zone to monitor signals received from the tag 10. The receiver 12 forms part of a network of receivers which may be installed in a particular building or the like. Each receiver 12 communicates via its repeater transmitter 14 to a central control unit (not shown). The central control unit may thus monitor and record authorised and/or unauthorised removal of the equipment.
5 Each tag 10 includes transmitter processor means in the form of a micro-controller 16 with associated support circuitry 18, and a long-life lithium battery 20. Selected 1/O ports of the micro-controller 16 are connected to a connection terminal 22 via which resident software to control the method of transmission of data is programmed 10 into the micro-controller 16. In use, a reed switch 24 is selectively enabled to toggle the micro-controller 16 into various states or modes of operation. In one mode of operation, the reed switch 24 may function as a sensing means, for example, to sense movement or the like. In another mode of operation, the reed switch 24 may function as data input means for feeding data into on-board memory of the micro-controller 16, e.g. data to uniquely identify the tag 10. The micro-controller 16 controls operation of transmitter circuitry 26 which transmits data, sourced from the micro-controller 16, to the receiver 12.
As can clearly be seen from the schematic circuit diagram shown in Figure 1, the micro-controller has one of its output ports connected directly to a transistor 25 of the transmitter circuitry 26. The transmitter circuitry 26 also includes associated passive components 27 which, in combination, define oscillator circuitry. Further, the transmitter circuitry 26 is not connected to the battery 20 but merely to ground and is powered exclusively by the modulation control signal from the micro-controller via line 28. Thus, the transmitter circuitry 26 is toggled between an "on" state in which it transmits a pulse via its antenna 29 and an "off" state in which it receives no power at all and is thus switched off completely.
In order to allow the transmitter circuitry 26 to stabilize for transmission of data, the micro-controller 16 feeds three pulses (part of one pulse 31 being shown in Figure 4), each pulse having a high portion of between about 20 and about 70 microseconds, typically about 60 microsecond, and a duty cycle of 50 %, to the transmitter circuitry via line 28. In particular, the modulation control signal generated by software of the micro-controller 16 has a first part followed by a second part. The first part includes the three high pulses of about 60 microsecond duration which are generated by the routine "pulse 4" in Table 2. As shown by arrow 150 in Table 2, the "pulse 4" subroutine (see arrow 152) is called three times. The high part of the modulation signal performs a dual function. Firstly, it powers up the transmitter circuitry 26 between, preferably, a totally switched off or dormant state, to an operative state in which it has stabilized sufficiently to transmit the second part comprising a pulse train of pulses of a substantially shorter duration. Secondly, the first part allows the receiver to distinguish a transmission from the tag from any other transmission e.g. an interference signal or the like from another source.
The micro-controller 16 controls transmission of unique identification data in the second part of the modulation control signal by means of a method, also in accordance with the invention, carried out in its resident software. The method used by the micro-controller 16 is set out in Table 2 (see arrow 154). In particular, the micro-controller 16 controls the transmitter circuitry 26 in such a fashion so that its transmitted or identification signal is both amplitude modulated and a pulse width modulated. The amplitude modulation of the transmitted signal varies between about 0% and about 100% modulation when representing both "1 " and "0" (see Figure 3). The transmitted signal has a 50% duty cycle and a "1 " is transmitted, for example, by a pulse with a 5 microseconds "on" time followed by a 5 microsecond "off" time resulting in a total pulse width of 10 microseconds (see Figure 4). A
"0", on the other hand, is transmitted by a pulse with an "on" time of 10 microseconds and an "off" time of 10 microseconds resulting in a total pulse width of 20 microseconds. The total duration of the pulse, i.e.
either 10 microseconds or 20 microseconds, that determines the state of a bit (see arrow 156 and following in Table 2). A plurality of pulses are transmitted in a burst of data and the burst of data is typically transmitted by the tag 10 periodically at a time interval of about 1 second. It is however to be appreciated that the pulses of the second part need not necessarily have a 50 % duty cycle since the high state of the pulse 33 (see Figure 4) acts as a marker or start portion identifying the start of a bit. Thereafter. a data portion defines the state of the bit, the duration 35 of the data portion being the total width of the pulse including its "off". In the present embodiment, the data portion 35 defines a high or low state of the bit by a 10 microsecond transmitter circuitry "off" time and a 20 microsecond transmitter circuitry "off" time respectively (see Figure 3). When the receiver 12 receives a transmission from the tag 10, it determines the total length or duration of the pulse and assigns a "1 " or "0" as shown in Figure 5.
Typically, the micro-controller 16 includes a counter which has its count reset upon installation of the battery 20 and thereafter increments its count each time the transmitter circuitry 26 transmits a burst of data. Data from the micro-controller 16 is fed to the transmitter circuitry 26 via line 28. It is to be appreciated that the data transmitted by the tag 10 may include a value of the count, unique identification data for identifying the tag 10, data sensed by the reed switch 24, or any other data.
The micro-controller 16 of the tag 10 does not use a crystal oscillator to control its operation but uses an internal RC oscillator provided in the chip. It is believed that the power consumption of the tag 10 is thereby reduced and start-up delays are faster. Accordingly, in order further to reduce the power consumption of the tag 10, the tag 10 is dormant or asleep between each burst of data which it transmits.
In order to achieve this, a second sleep or stand-by RC oscillator provided in the micro-controller 16, is used. As shown in block 30, after the predetermined time interval, typically about 0.7 to about 1 s (see arrow 158 in Table 2) has lapsed, the micro-controller 16 is instructed to start/wake-up. Thereafter, the unique identification code and other data to be transmitted by the tag 10 is set up as shown in block 32, whereafter the data is configured in a serial form as shown in block 34 where the next/first byte of the remaining bytes (designated by X) is fed to the transmitter circuitry 26 as shown in block 36. The micro-controller 16 then (see block 38) analyses each bit in the serial string.
If the bit is at logic "1 ", the transmitter circuitry 26 is activated to transmit a pulse which is high for 5 microseconds as shown in block 40 and, thereafter, a low of 5 microseconds is implemented as shown is block 42 to ensure that the transmitted signal has a 50% duty cycle and a total pulse width of 10 microseconds. However, if the bit is at logic "0", the transmitter circuitry 26 is then instructed to transmit a pulse which is high for 10 microseconds as shown is block 44 followed by a low of 10 microseconds, as shown in block 46, providing a 50% duty cycle and a total pulse width of 20 microseconds when a "0" is transmitted.
If all the bits of the byte have been transmitted, as shown in block 48, then the micro-controller 16 is instructed to increment its pointer to the next byte as shown in block 50 (see also arrow 154 in Table 2). If, however, all 8 bits of the byte have not been transmitted, then the micro-controller 16 is instructed to fetch the next bit as shown in block 52 and the procedure as set out above is repeated. As shown in block 54, if the last byte to be sent in the burst has been sent, then the micro-controller 16 goes into a sleep or dormant mode (see block 55) for the predetermined time interval. However, if the last byte has not been sent , then the micro-controller 16 fetches the next byte as shown in block 34.
Referring in particular to Figure 2 of the drawings, the receiver 12 includes a receiver processor 56 defined by a receiver micro-controller 58, for example, a PIC 16F84 or the like. Selected I/O ports of the receiver micro-controller 58 are connected to I/O terminals 60 to allow resident software to be programmed into the micro-controller 58 by an external device such as a PC or the like. The receiver micro-controller 58 is connected via line 62 to the repeater transmitter 14 which is substantially similar to the transmitter circuitry 10. The repeater transmitter 14 includes a transistor 64 which is selectively switched on and off by the receiver micro-controller 58 to generate "1 "s and "0"s thereby repeating a signal received by the receiver 12 to the central monitoring or control unit. As in the case of the transmitter circuitry 26, the transmitter 14 sources its operational power directly from a modulation control signal provided via an output port of the micro-controller 58 via line 62.
The identification signal transmitted by the tag 10 is received by receiver circuitry 68 which has its output signal fed into an 5 RF amplifier 74 and into demodulation circuitry 70 via line 72. The demodulation circuitry 70 has its output connected, via a decoupling capacitor 76, to amplification circuitry generally indicated by reference numeral 78 which comprises a series of operational amplifiers. An output stage of the operational amplifiers is connected via line 80 to a 10 port of the receiver micro-controller 58. Power to the various components of the receiver 12 is provided by a power supply unit 82.
Selected I/O ports of the receiver micro-controller 58 are connected to a programming terminal 84 in which appropriate software to control the method of operation of the receiver 12 is fed into the 15 receiver micro-controller 58. The method of controlling the receiver 12 is set out in Table 1 and described in more detail below.
Referring in particular to Figure 5 of the drawings, the receiver software first includes the method of resetting the bit/byte information as shown in block 86. The initialization of the bit/byte information and various other operating parameters is generally indicated by arrow 160 and following in Table 1. Arrow 162 marks the start of the routine where the ports of the micro-controller 58 are initialized. The software implementing the method then waits for a high input as shown in block 88. When a high input is received, the duration of the pulse is monitored. In particular, the routine "HIG 1 " (see arrow 164 in Table 1) determines the duration for which the pulse is high and the routine "HIG2" determines the duration for which the pulse is low lsee arrow 166). The sum of the high and low durations is then calculated to check if the total duration is within an acceptable range which is typically between about 50 and about 70 microseconds. Thus, the time duration or interval between the pulses is counted or determined until a next high is received as shown in block 90. If the interval is 10 microseconds (i.e a five microsecond high followed by a five microsecond low) as shown in block 92, then the incoming bit of the burst of data received from the tag 10 is a "1 " as shown in block 94. Thereafter the bit counter is incremented by one as shown in block 96 and if it is the last bit of the count (see block 98) then the bit/byte is reset as shown by line 100 leading into block 86. If, however, the interval is not equal to 10 microseconds, then the interval is timed to determine whether or not it is equal to about 20 microseconds (i.e. 10 microsecond high followed by a 10 microsecond low). If the delay is equal to about 20 microseconds, then the bit is recognized as a "0" as shown in block 104 and, once again, the bit counter is incremented as shown in block 96. However, if the interval is not equal to 20 microseconds then the method includes resetting the bits/byte as shown by line 106 leading to the block 86.
The routine for recognizing a "1 " or a "0" is generally indicated by arrow 168 in Table 1. Table 1 also includes various other routines, e.g. an RS
232 routine, for feeding data to other devices. It is to be appreciated that the receiver micro-controller 58 may include a variety of additional routines to allow communication of data received from the tag 10 to be communicated to other devices.
The inventor believes that the invention, as illustrated, provides an identification system including a method of communicating data from the tag 10 to the receiver 12 which has reduced power consumption characteristics. The features of the invention that enhance the low power consumption characteristics include the powering of the transmitter circuitry 26 by means of the modulation control signal and the arrangement in which the state of a bit is determined by the "off"
time of the transmitter circuitry 26. Power consumption of the tag 10 is also substantially reduced when the tag 10 is in its sleep or dormant mode.
Accordingly, the transmitter circuitry, under control of the processor means may be arranged periodically to transmit the identification signal is bursts at a predetermined time interval, for example about 1 s.
Preferably, the identification signal has a duty cycle of about 50 %.
Data is typically transmitted in a digital fashion as a series of "1 "s and "0"s. Typically, a "0" is transmitted by a transmitter on time being about 10 microseconds followed by an off time of equal duration, and a "1 " is transmitted by the transmitter being on about 5 microseconds followed by an off time of equal duration so that the signal has a 50 % duty cycle. It is however to be appreciated that any two different transmission time intervals, controlled by the transmitter processor may be used to communicate a "1 " or a "0". Further, the duty cycle of the pulses may vary.
Further in accordance with the invention, there is provided an identification system which includes a plurality of electronic tags, each tag including processor means programmed to provide a modulation control signal which includes unique identification data which at least identifies the tag; and transmitter circuitry connected to the processor means and to an antenna for transmission of the unique identification data, the transmitter circuitry being substantially powered by the modulation control signal; and at least one electronic tag receiver configured to receive a transmission from the tag.
The transmitter circuitry of the electronic tag may be exclusively powered by the modulation control signal of the processor 5 means.
The transmitter circuitry may include passive components and a transistor directly driven by the processor means. The transistor in combination with the passive components may form an integral part of the transmitter circuitry which is powered up by the modulation control signal.
The processor means may be configured to provide the modulation control signal with a first part followed by a second part, the first part including at least one high pulse of such a duration so as to provide sufficient power to the transmitter circuitry at least partially to stabilize for transmission of the second part which includes data defined in a plurality of pulses which are of a substantially lesser duration.
The first part of the modulation control signal may include a plurality of high pulses that, in combination, provide an identification signal to signal detection means of the electronic tag receiver for receiving a transmission from the electronic tag.
Each pulse of the second part of the modulation signal may include a start portion for identifying a start of a bit and a data portion for identifying a state of the bit of data, the duration of the data portion selectively defining a high and a low state of the bit under control of the processor means.
The high bit may be defined by a shorter data portion during which the transmitter circuitry is switched off and the low bit is defined by a longer data portion during which the transmitter circuitry is switched off.
Still further in accordance with the invention, there is provided a method of communicating data from an electronic tag, the method including driving transmitter circuitry of the tag with a modulation control signal which substantially powers the transmitter circuitry.
Typically, the modulation control signal exclusively powers the transmitter circuitry.
The transmitter circuitry may include an oscillator which is arranged to oscillate at its fundamental frequency when data is being transmitted and stop oscillating when data is not transmitted.
Accordingly, the method may include selectively modulating a fundamental frequency of the oscillator when data is being transmitted and disabling the oscillator when data is not being transmitted.
The modulation control signal may include a first part followed by a second part, the first part including at least one high pulse of such a duration so as to provide sufficient power to the transmitter circuitry at least partially to stabilize it for transmission of the second part which includes data defined in a plurality of pulses which are of a substantially lesser duration.
The first part of the modulation control signal may include a plurality of high pulses that, in combination, provide an identification signal to a tag receiver for receiving a transmission from the electronic tag.
Each pulse of the second part of the modulation signal may include a start portion for identifying a start of a bit and a data portion for identifying a state of the bit of data, the duration of the data portion selectively defining a high and a low state of the bifi under control of the processor means.
The high bit may be defined by a shorter data portion during which the modulation control signal is switched off and the low bit may defined by a longer data portion during which the modulation control signal is switched off.
The processor means is preferably a micro-controller which includes an internal RC oscillator on which the modulation control signal is dependent and the micro-controller is arranged to enter a sleep mode between data transmissions thereby to reduce power consumption. The micro-controller may define a transmitter processor which is typically a PIC 12C509 or the like, which is programmed with appropriate software to execute the method of controlling the transmitter.
Still further in accordance with the invention, there is provided a receiver for receiving a transmission from one of a plurality of WO 00/52636 . PCT/IB00/00220 electronic tags, the transmission including a first part and a second part and the receiver including detection circuitry for detecting the first part and the second part of the transmission, the first part including at least one high pulse in response to which the receiver monitors reception of the second part which includes data defined in a plurality of pulses which are of a substantially lesser duration; and timing means for timing the duration of each of the pulses in the second part and selectively generating a high or a low output defining a bit dependent upon the duration of the pulse.
The receiver may include pulse width detection circuitry for decoding the identification signal.
The receiver may include receiver circuitry connected to an antenna for receiving the identification signal from at least one electronic tag;
demodulation circuitry connected to the receiver circuitry for demodulating the identification signal;
amplification circuitry connected to the demodulation circuitry via a capacitive link; and receiver processor circuitry connected to the amplification circuitry for processing the identification signal after demodulation thereof.
The receiver may include a repeater transmitter for re-transmitting the identification signal to a central control unit. Typically, each tag is attached to an item of value, e.g. a personal computer or other valuable item, located in a particular zone and a receiver monitors the transmission of identification signals in the zone. The central control unit may thus be in wireless communication with a plurality of zones each of which include a receiver monitoring associated tags located on valuable items or equipment in the zone.
The invention is now described, by way of example, with reference to the accompanying diagrammatic drawings.
In the drawings, Figure 1 shows a schematic circuit diagram of a electronic tag in accordance with the invention;
Figure 2 shows a schematic circuit diagram of a receiver, also in accordance with the invention;
Figure 3 shows a flow chart of a method of controlling transmission of data via the tag of Figure 1;
Figure 4 shows an example of a burst of data transmitted by the transmitter; and Figure 5 shows a flow chart of a method of decoding data by the receiver of Figure 2.
Referring to the drawings, an identification system, in accordance with the invention, is provided which includes a plurality of transmitters which are in the form of electronic tags 10 (also in accordance with the invention and only one of which is shown in the drawings), each of which is associated with at least one receiver 12 (see Figure 2). Typically, valuable items or equipment to be monitored in a selected zone, e.g. computers in a particular office area, are each fitted with a tag 10 and the receiver 12 is located in the zone to monitor signals received from the tag 10. The receiver 12 forms part of a network of receivers which may be installed in a particular building or the like. Each receiver 12 communicates via its repeater transmitter 14 to a central control unit (not shown). The central control unit may thus monitor and record authorised and/or unauthorised removal of the equipment.
5 Each tag 10 includes transmitter processor means in the form of a micro-controller 16 with associated support circuitry 18, and a long-life lithium battery 20. Selected 1/O ports of the micro-controller 16 are connected to a connection terminal 22 via which resident software to control the method of transmission of data is programmed 10 into the micro-controller 16. In use, a reed switch 24 is selectively enabled to toggle the micro-controller 16 into various states or modes of operation. In one mode of operation, the reed switch 24 may function as a sensing means, for example, to sense movement or the like. In another mode of operation, the reed switch 24 may function as data input means for feeding data into on-board memory of the micro-controller 16, e.g. data to uniquely identify the tag 10. The micro-controller 16 controls operation of transmitter circuitry 26 which transmits data, sourced from the micro-controller 16, to the receiver 12.
As can clearly be seen from the schematic circuit diagram shown in Figure 1, the micro-controller has one of its output ports connected directly to a transistor 25 of the transmitter circuitry 26. The transmitter circuitry 26 also includes associated passive components 27 which, in combination, define oscillator circuitry. Further, the transmitter circuitry 26 is not connected to the battery 20 but merely to ground and is powered exclusively by the modulation control signal from the micro-controller via line 28. Thus, the transmitter circuitry 26 is toggled between an "on" state in which it transmits a pulse via its antenna 29 and an "off" state in which it receives no power at all and is thus switched off completely.
In order to allow the transmitter circuitry 26 to stabilize for transmission of data, the micro-controller 16 feeds three pulses (part of one pulse 31 being shown in Figure 4), each pulse having a high portion of between about 20 and about 70 microseconds, typically about 60 microsecond, and a duty cycle of 50 %, to the transmitter circuitry via line 28. In particular, the modulation control signal generated by software of the micro-controller 16 has a first part followed by a second part. The first part includes the three high pulses of about 60 microsecond duration which are generated by the routine "pulse 4" in Table 2. As shown by arrow 150 in Table 2, the "pulse 4" subroutine (see arrow 152) is called three times. The high part of the modulation signal performs a dual function. Firstly, it powers up the transmitter circuitry 26 between, preferably, a totally switched off or dormant state, to an operative state in which it has stabilized sufficiently to transmit the second part comprising a pulse train of pulses of a substantially shorter duration. Secondly, the first part allows the receiver to distinguish a transmission from the tag from any other transmission e.g. an interference signal or the like from another source.
The micro-controller 16 controls transmission of unique identification data in the second part of the modulation control signal by means of a method, also in accordance with the invention, carried out in its resident software. The method used by the micro-controller 16 is set out in Table 2 (see arrow 154). In particular, the micro-controller 16 controls the transmitter circuitry 26 in such a fashion so that its transmitted or identification signal is both amplitude modulated and a pulse width modulated. The amplitude modulation of the transmitted signal varies between about 0% and about 100% modulation when representing both "1 " and "0" (see Figure 3). The transmitted signal has a 50% duty cycle and a "1 " is transmitted, for example, by a pulse with a 5 microseconds "on" time followed by a 5 microsecond "off" time resulting in a total pulse width of 10 microseconds (see Figure 4). A
"0", on the other hand, is transmitted by a pulse with an "on" time of 10 microseconds and an "off" time of 10 microseconds resulting in a total pulse width of 20 microseconds. The total duration of the pulse, i.e.
either 10 microseconds or 20 microseconds, that determines the state of a bit (see arrow 156 and following in Table 2). A plurality of pulses are transmitted in a burst of data and the burst of data is typically transmitted by the tag 10 periodically at a time interval of about 1 second. It is however to be appreciated that the pulses of the second part need not necessarily have a 50 % duty cycle since the high state of the pulse 33 (see Figure 4) acts as a marker or start portion identifying the start of a bit. Thereafter. a data portion defines the state of the bit, the duration 35 of the data portion being the total width of the pulse including its "off". In the present embodiment, the data portion 35 defines a high or low state of the bit by a 10 microsecond transmitter circuitry "off" time and a 20 microsecond transmitter circuitry "off" time respectively (see Figure 3). When the receiver 12 receives a transmission from the tag 10, it determines the total length or duration of the pulse and assigns a "1 " or "0" as shown in Figure 5.
Typically, the micro-controller 16 includes a counter which has its count reset upon installation of the battery 20 and thereafter increments its count each time the transmitter circuitry 26 transmits a burst of data. Data from the micro-controller 16 is fed to the transmitter circuitry 26 via line 28. It is to be appreciated that the data transmitted by the tag 10 may include a value of the count, unique identification data for identifying the tag 10, data sensed by the reed switch 24, or any other data.
The micro-controller 16 of the tag 10 does not use a crystal oscillator to control its operation but uses an internal RC oscillator provided in the chip. It is believed that the power consumption of the tag 10 is thereby reduced and start-up delays are faster. Accordingly, in order further to reduce the power consumption of the tag 10, the tag 10 is dormant or asleep between each burst of data which it transmits.
In order to achieve this, a second sleep or stand-by RC oscillator provided in the micro-controller 16, is used. As shown in block 30, after the predetermined time interval, typically about 0.7 to about 1 s (see arrow 158 in Table 2) has lapsed, the micro-controller 16 is instructed to start/wake-up. Thereafter, the unique identification code and other data to be transmitted by the tag 10 is set up as shown in block 32, whereafter the data is configured in a serial form as shown in block 34 where the next/first byte of the remaining bytes (designated by X) is fed to the transmitter circuitry 26 as shown in block 36. The micro-controller 16 then (see block 38) analyses each bit in the serial string.
If the bit is at logic "1 ", the transmitter circuitry 26 is activated to transmit a pulse which is high for 5 microseconds as shown in block 40 and, thereafter, a low of 5 microseconds is implemented as shown is block 42 to ensure that the transmitted signal has a 50% duty cycle and a total pulse width of 10 microseconds. However, if the bit is at logic "0", the transmitter circuitry 26 is then instructed to transmit a pulse which is high for 10 microseconds as shown is block 44 followed by a low of 10 microseconds, as shown in block 46, providing a 50% duty cycle and a total pulse width of 20 microseconds when a "0" is transmitted.
If all the bits of the byte have been transmitted, as shown in block 48, then the micro-controller 16 is instructed to increment its pointer to the next byte as shown in block 50 (see also arrow 154 in Table 2). If, however, all 8 bits of the byte have not been transmitted, then the micro-controller 16 is instructed to fetch the next bit as shown in block 52 and the procedure as set out above is repeated. As shown in block 54, if the last byte to be sent in the burst has been sent, then the micro-controller 16 goes into a sleep or dormant mode (see block 55) for the predetermined time interval. However, if the last byte has not been sent , then the micro-controller 16 fetches the next byte as shown in block 34.
Referring in particular to Figure 2 of the drawings, the receiver 12 includes a receiver processor 56 defined by a receiver micro-controller 58, for example, a PIC 16F84 or the like. Selected I/O ports of the receiver micro-controller 58 are connected to I/O terminals 60 to allow resident software to be programmed into the micro-controller 58 by an external device such as a PC or the like. The receiver micro-controller 58 is connected via line 62 to the repeater transmitter 14 which is substantially similar to the transmitter circuitry 10. The repeater transmitter 14 includes a transistor 64 which is selectively switched on and off by the receiver micro-controller 58 to generate "1 "s and "0"s thereby repeating a signal received by the receiver 12 to the central monitoring or control unit. As in the case of the transmitter circuitry 26, the transmitter 14 sources its operational power directly from a modulation control signal provided via an output port of the micro-controller 58 via line 62.
The identification signal transmitted by the tag 10 is received by receiver circuitry 68 which has its output signal fed into an 5 RF amplifier 74 and into demodulation circuitry 70 via line 72. The demodulation circuitry 70 has its output connected, via a decoupling capacitor 76, to amplification circuitry generally indicated by reference numeral 78 which comprises a series of operational amplifiers. An output stage of the operational amplifiers is connected via line 80 to a 10 port of the receiver micro-controller 58. Power to the various components of the receiver 12 is provided by a power supply unit 82.
Selected I/O ports of the receiver micro-controller 58 are connected to a programming terminal 84 in which appropriate software to control the method of operation of the receiver 12 is fed into the 15 receiver micro-controller 58. The method of controlling the receiver 12 is set out in Table 1 and described in more detail below.
Referring in particular to Figure 5 of the drawings, the receiver software first includes the method of resetting the bit/byte information as shown in block 86. The initialization of the bit/byte information and various other operating parameters is generally indicated by arrow 160 and following in Table 1. Arrow 162 marks the start of the routine where the ports of the micro-controller 58 are initialized. The software implementing the method then waits for a high input as shown in block 88. When a high input is received, the duration of the pulse is monitored. In particular, the routine "HIG 1 " (see arrow 164 in Table 1) determines the duration for which the pulse is high and the routine "HIG2" determines the duration for which the pulse is low lsee arrow 166). The sum of the high and low durations is then calculated to check if the total duration is within an acceptable range which is typically between about 50 and about 70 microseconds. Thus, the time duration or interval between the pulses is counted or determined until a next high is received as shown in block 90. If the interval is 10 microseconds (i.e a five microsecond high followed by a five microsecond low) as shown in block 92, then the incoming bit of the burst of data received from the tag 10 is a "1 " as shown in block 94. Thereafter the bit counter is incremented by one as shown in block 96 and if it is the last bit of the count (see block 98) then the bit/byte is reset as shown by line 100 leading into block 86. If, however, the interval is not equal to 10 microseconds, then the interval is timed to determine whether or not it is equal to about 20 microseconds (i.e. 10 microsecond high followed by a 10 microsecond low). If the delay is equal to about 20 microseconds, then the bit is recognized as a "0" as shown in block 104 and, once again, the bit counter is incremented as shown in block 96. However, if the interval is not equal to 20 microseconds then the method includes resetting the bits/byte as shown by line 106 leading to the block 86.
The routine for recognizing a "1 " or a "0" is generally indicated by arrow 168 in Table 1. Table 1 also includes various other routines, e.g. an RS
232 routine, for feeding data to other devices. It is to be appreciated that the receiver micro-controller 58 may include a variety of additional routines to allow communication of data received from the tag 10 to be communicated to other devices.
The inventor believes that the invention, as illustrated, provides an identification system including a method of communicating data from the tag 10 to the receiver 12 which has reduced power consumption characteristics. The features of the invention that enhance the low power consumption characteristics include the powering of the transmitter circuitry 26 by means of the modulation control signal and the arrangement in which the state of a bit is determined by the "off"
time of the transmitter circuitry 26. Power consumption of the tag 10 is also substantially reduced when the tag 10 is in its sleep or dormant mode.
