The such table of nonvolatile memory stores that is provided with in receiver 10 wherein stores the information (distinguishing new equipment and old equipment) of the classification of the address of whole repeater 30A and 30B and detecting device 41A, 41B, 42A and 42B and indication equipment.Receiver 10 can carry out poll or addressing by utilization address stored in this table, thus the transmission of the data (comprising control command) of execution and each terminal device.
Next, will describe in detail by receiver (watch-dog) 10 carry out to the data transmission of terminal device 30A, the 41A of traditional type and 42A and to the data transmission of the terminal 30B with new function, 41B and 42B.
Fig. 3 A to 3C and Fig. 4 A and Fig. 4 B illustrate the example that is used for sending at watch-dog according to an embodiment of the invention the serial data of data, and Fig. 2 illustrates the definition of the unit waveform of the serial data among pie graph 3A to 3C and Fig. 4 A and Fig. 4 B.In Fig. 3 A to 3C and Fig. 4 A and Fig. 4 B, be meant that by the waveform shown in the dotted line bit data that is sent out is not scheduled to, import any of " 0 " and " 1 " according to the data that will be sent out or return, and represent that by the waveform shown in the shade from the data that terminal equipment side is returned are " 1 ".Can by for example in above-mentioned JP-A-60-028341 the prior art of invention disclosed realize sending simultaneously with return data and via the system of two transmission lines supply powers.
Basically export from receiver 10 at the serial data shown in Fig. 3 A to 3C and Fig. 4 A and Fig. 4 B.Fig. 3 A to 3C illustrates the serial data that is used for sending with the terminal device of traditional type data.
Fig. 3 A illustrates by receiver 10 and uses, is used for from the serial data of each terminal device collection classified information, Fig. 3 B illustrates and is used to collect the relevant information of monitoring (in this manual, it is called as simulated data), for example terminal unit status, detection limit or the like, and Fig. 3 illustrates by receiver 10 and uses, is used for controlling the serial data of each terminal device by sending a command to terminal device.
As shown in Figure 3, the transmission data string of Shi Yonging comprises in the present embodiment: beginning district A1, and it stores start bit (on transfer path, this start bit becomes initial pulse); Pattern district A2, the information that its this serial data of storage indication is used for acquisition of information or is used for control terminal; Address area A3, its storage is as the information of the address of the identifying information of terminal device; Command area A4, the information of the content of the order that is used for terminal device is indicated in its storage; Return data district A5, it stores return data; And end zone A6, it stores position of rest (on transfer path, this position of rest becomes stop pulse).
In the A3 of address area, memory address and the check bit that is used for bug check.In command area A4, the order position of rest that memory command sign indicating number, check bit sum directive command stop.In return data district A5, data, check bit sum that storage returns start bit (sub-start bit), turn back to receiver from terminal device return position of rest (sub-position of rest).
From the waveform of the return data district A5 of receiver 10 output is the circulation of " 0 ", and shown in Fig. 2 (B), and this waveform changes according to the data of returning from terminal device, shown in shade or dotted line among Fig. 3 A to 3C and Fig. 4 A and Fig. 4 B.This variation of waveform is received device and directly or indirectly detects, and therefore can discern from the data of terminal device output.The beginning district of return data district A5 return start bit and the position of rest that returns in the end zone of return data district A5 is set to output " 1 " by terminal device.Therefore, receiver is monitored these positions, if they are not " 1 ", then receiver is treated to error of transmission with it.
(this serial data is used for order is sent to terminal device from receiver 10) can omit return data district A5 in the serial data of Fig. 3 C.Even in this case, can be provided with and return position of rest.Equally, in the serial data of Fig. 3 C, by return data district A5 is set, serial data has the structure identical with other serial data.Therefore, the processing procedure of the serial data of Fig. 3 C can be identical with the processing procedure of other serial datas, to simplify its design.If in the serial data of Fig. 3 C, omitted return data district A5, the transmission from the receiver to the terminal can be regarded as access by addressing.In this case, whether the information of pattern district A2 can be considered to indicate from the transmission of receiver 10 corresponding to the information of poll or addressing.
Fig. 4 A illustrates by receiver 10 and uses, is used for from the serial data of terminal device collection terminal classified information with new function, and Fig. 4 B illustrates by receiver 10 and uses, is used for collecting from the terminal device with new function the serial data of the relevant information of monitoring (for example SOT state of termination and detection limit).Since by receiver 10 use, to be used for that order is sent to the terminal with new function identical with the serial data of the terminal that is used for traditional type shown in Fig. 3 C with the serial data of controlling this terminal, so will omit its diagram and explanation.
Shown in Fig. 4 A and 4B, to the return data district A5 that wherein stores return data, the serial data that is sent to the terminal device with new function is identical with the serial data of the terminal that is used for traditional type from the beginning district A1 that wherein stores start bit.On the other hand, be different from the waveform that the end zone A6 of the serial data of the terminal that is used for traditional type shown in Fig. 3 A and 3B is preserved at the waveform of storing among the A6 of end zone.Especially, when the waveform of " 1 " shown in (A) among the waveform (position of rest) of the end zone A6 of the serial data of the terminal that is used for traditional type and Fig. 2 is identical, the waveform of " 0 " shown in (B) among the waveform of in the A6 of the end zone of the serial data that is sent to terminal device, being stored and Fig. 2 identical (with the waveform difference shown in (A) among Fig. 2) with new function.
(see Fig. 4 A as being stored in serial data, this serial data comprises that classified information collects order) expansion return data district A7 in return data, for example, be stored under the situation among the return data district A5 at the code of indication " repeater ", the code of differentiation " repeater that is used for fire report " and " repeater that is used for Smoke prevention " can be arranged as classification.In an identical manner, be stored under the situation among the return data district A5, can store and return the code of distinguishing detecting device with different detection methods at the code of indication " thermal detector " or " smoke-detectors " as classification.
Terminal device with new function has detection and outputs to the serial data of transfer path 20 and distinguish that the waveform that comprises is the function of the waveform shown in the waveform shown in Fig. 2 (A) or Fig. 2 (B) among regional A6 from receiver 10, if the waveform in regional A6 is the waveform shown in Fig. 2 (B), then terminal device is carried out return data is carried on operation on the waveform among the expansion return data district A7 after the regional A6.That is, the waveform shown in Fig. 2 (B) that is comprised among the regional A6 is as the data spread signal (extension bits) of the terminal device with new function.
On the other hand, the waveform that is comprised in regional A6 is under the situation of the waveform shown in Fig. 2 (A), and the terminal device with new function is detecting the moment end data return of this waveform.Owing to not having, the terminal device that is connected to the traditional type of transfer path do not distinguish that the waveform that comprises is the function of the waveform shown in the waveform shown in Fig. 2 (A) or Fig. 2 (B) in regional A6, even if therefore the serial data shown in Fig. 4 A and 4B is sent to the terminal device of this traditional type, identical operations under the situation that the terminal device of this traditional type is also carried out and the serial data shown in Fig. 3 A and 3B is sent out.That is, the terminal device of traditional type does not send response for regional A6 and regional A7.
Fig. 5 is illustrated in the data transmission and processing process in the terminal device of traditional type.The terminal device of traditional type is monitored the signal on the transmission lines constantly, if there is signal to be transfused to, the terminal device of this traditional type determines at first whether this signal is start bit (initial pulse) (step S1).Here, not start bit ("No") if determine this signal, the terminal device end operation of traditional type and do not carry out any processing then.If determine that this signal is start bit ("Yes"), then by the waveform among the checking mode district A2, whether the pattern of distinguishing is meant information gathering to the terminal device of traditional type in step S2.
If deterministic model is information gathering pattern ("Yes") in step S2, then terminal device determine the address that in the A3 of address area, comprised whether with than the address of distributing to this terminal device self consistent (step S3).Here, if determine this address not with it self address consistent ("No"), then terminal device end process.If determine the address consistent ("Yes") of this address and it self, then terminal device by checking the waveform among the command area A4, determines whether this order is the order that is used to collect analog information (for example terminal unit status or the like) in step S4.
If determine that in step S4 order is information gathering order ("Yes"), then terminal device is carried out operation (step S6) of preparing the simulated data that will return and the operation (step S7) of exporting this return data of preparing, and returns step S1.
On the other hand, in step S4,, determine then whether this order is to be used for the order that classified information is collected if the waveform from command area A4 determines that the serial data that is received is not the order ("No") that is used to collect analog information.Here, be that classified information is collected order ("Yes") if determine this order, then terminal device is carried out the operation (step S12) of output return data (classification code), and returns step S1.
Equally, if in step S2, the waveform from pattern district A2 determines that described pattern is not information gathering pattern ("No"), and then terminal proceeds to step S15, and determines whether this pattern is mode control terminal.Here, if determine that this pattern is not mode control terminal ("No"), then terminal device end operation.If determining this pattern is mode control terminal ("Yes"), then terminal device is determined the address that comprised whether consistent with the address that is assigned to terminal device self (step S16) in the A3 of address area.If determine this address not with it self address consistent ("No"), then terminal device end operation.If determine the address consistent ("Yes") of this address and it self, then in step S17, terminal device is according to the control command among the command area A4, generates the control signal in the outlet terminal equipment also.Then, this terminal is carried out control command that output received as operation (step 818), the end operation of return data and turn back to step S1 then.
Fig. 6 is illustrated in the data transfer operation in the terminal device with new function.The difference of the process flow diagram of Fig. 6 and the process flow diagram of Fig. 5 is that the process flow diagram of Fig. 6 comprises: after the return data output function of the step S7 in the process flow diagram of Fig. 5, determine whether to have the operation (step S8) of spread signal (expansion pulse) in serial data; When in step S8, determining to have spread signal, add and export the operation (step S9) of return data; After the return data output function of the step S12 of the process flow diagram of Fig. 5, determine in serial data, after return data district A5, whether to exist the operation (step S13) of spread signal; And when in step S13, determining to have spread signal, add and export the operation (S14) of return data.In other respects, operation is identical with the operation of process flow diagram among Fig. 5, so will omit the explanation of its repetition.
As mentioned above, whether the terminal device with new function exists spread signal after having the return data district A5 that determines in serial data, and if determine to have spread signal then the function of adding and export return data.On the other hand, the terminal device of traditional type does not have this function.Therefore, though at the terminal device of traditional type and terminal device with new function under coexistence on the identical transfer path 20 and situation about linking together, any terminal device can normally be carried out data transmission.
Equally, owing to the terminal device of traditional type with have the terminal device of new function in response to carrying out aforesaid operations from the data transmission of receiver 10, therefore, if the information of the address of registering in the table of being stored in receiver 10, indicating terminal classification and differing from each other from the classified information of terminal device collection by transfer path 20, then receiver 10 can be based on collecting the response of order and detecting connection error classified information from terminal device.
Especially, for example, if the terminal device of traditional type has been connected on the point (address) that terminal device with new function just should connect, even receiver 10 outputs have wherein increased the serial data that spread signal is arranged so, the terminal device of traditional type can be in response to the growth data district yet, so receiver 10 can detect the terminal device with new function and is not connected.Equally, even under the situation of terminal device in response to the growth data district, if the classified information of returning is different from the data in the table that is kept in receiver 10, then receiver 10 can detect connection error.
In having the terminal device of new function, if necessary, can suitably change operation according to the process flow diagram of Fig. 5 and Fig. 6.That is, in typical policer operation, can carry out data aggregation and control by transmission that can not the expanded data string, shown in Fig. 3 A to 3C, and the system that embodiments of the invention are applied to it can carry out this operation.
Although describe the present invention with warp in detail based on embodiment, the present invention is not restricted to the foregoing description.For example, although described the system that wherein uses thermal detector and smoke-detectors in an embodiment, fire detector is not restricted to above-mentioned these.Can be with various detecting devices, for example the ion-type fire detector, can detect the fire detector or the like of the complexity of heat and smog simultaneously, be connected on the transfer path.Equally, the arrangement in the zone of the serial data that sends by transfer path is not restricted to those shown in Fig. 3 A to 3C or Fig. 4 A and the 4B, and for example, memory block, address and pattern district can be with opposite being disposed in order.
