The first control unit 15 compares the stored information and the acquired information for each repeater 3, and outputs according to the comparison result. The “output according to the comparison result” is, for example, an output of a signal to the display unit 12 for the first control unit 15 to display the comparison result on the display unit 12. The configuration in which the first control unit 15 stores information on the type and sensitivity of each fire detector 2 in the first storage unit 11 is not essential and can be omitted.

OK button, cancel button) and so on. By confirming the display contents of the display unit 12 and operating the operation unit 13, the operator confirms the stored information, stores (registers), changes, and discards the acquired information in the first storage unit 11. (Delete) can be done. Hereinafter, the storage (registration) of the acquired information in the first storage unit 11, the change and destruction of the registered information are also referred to as the acquisition information or the management of the registered information.

The operation unit 13 receives an operation for transmitting an arbitrary signal from the fire receiver 1 to the repeater 3 and each fire receiver 1 by operating a plurality of switches.

The first communication line L1 is connected to the third communication unit 33. The second communication line L2 is connected to the second communication unit 32. The conversion unit 35 performs protocol conversion between the second communication unit 32 and the third communication unit 33.

The second storage unit 31 has a non-volatile memory such as EEPROM. The second storage unit 31 stores the first address information. The first address information is address information that has a one-to-one correspondence with a plurality of repeaters 3, and is different for each repeater 3. The first address information is, for example, information represented by at least one of a sequence and a character string. The first address information is written in the second storage unit 31 of each repeater 3 via an address setting device or the like, for example, before the operator installs each repeater 3 in the building.

Further, the second storage unit 31 stores a plurality of second address information acquired from the plurality of fire detectors 2 connected to the second communication line L2.

The second control unit 34 is realized, for example, by the microcomputer included in the repeater 3 reading a program or the like from the memory built in the microcomputer and executing the program. The second control unit 34 communicates with the plurality of fire detectors 2 based on the content included in the arbitrary signal received by the third communication unit 33. For example, when the third communication unit 33 receives the first request signal, the first control unit 15 communicates with each of the plurality of fire detectors 2 to acquire a plurality of second address information, and the plurality of second control units 15 acquire the plurality of second address information. The first response signal including the address information is transmitted to the fire receiver 1. In other words, the repeater 3 can collect a plurality of second address information into one and transmit it to the fire receiver 1. The details of the operation of the second control unit 34 will be described in "(5) Procedure for storing the first and second address information in the first storage unit".

(4) Configuration of Fire Detectors The plurality of fire detectors 2 have a fourth communication unit 21, a third control unit 22, and a third storage unit 23. The second communication line L2 is connected to the fourth communication unit 21. The third control unit 22 is realized, for example, by the microcomputer included in the fire detector 2 reading a program or the like from the memory built in the microcomputer and executing the program. The third control unit 22 controls the fourth communication unit 21 and the third storage unit 23. Further, the third control unit 22 acquires the detection result from a sensor (for example, a smoke detection element, a heat detection element, etc.) (not shown).

The fourth communication unit 21 of the plurality of fire detectors 2 is connected to the second communication unit 32 of the repeater 3 via the second communication line L2, respectively. The second communication line L2 has at least two electric wires. The fourth communication unit 21 is connected between the two electric wires of the second communication line L2 by a crossover wiring method. Hereinafter, the electric wire that electrically connects the plurality of fourth communication units 21 and the second communication unit 32 is referred to as a second communication line L2. Each of the plurality of fourth communication units 21 can communicate with the second communication unit 32 via the second communication line L2. The fourth communication unit 21 changes the voltage between the two electric wires of the second communication line L2 and transmits a signal to the second communication unit 32 of the repeater 3. On the other hand, the repeater 3 changes the voltage between the two electric wires of the second communication line L2 and transmits the signal to the plurality of fourth communication units 21. The communication method between the fourth communication unit 21 and the second communication unit 32 is, for example, a time-division communication method.

The third storage unit 23 has a non-volatile memory such as EEPROM. The third storage unit 23 stores the second address information. The second address information is address information corresponding to a plurality of fire detectors 2 on a one-to-one basis, and is different for each fire detector 2. The second address information is, for example, information represented by a sequence and a character string. The second address information is written in the third storage unit 23 via an address setting device or the like before each fire detector 2 is installed in the building.

(5) Procedure for storing the first and second address information in the first storage unit Refer to FIG. 3 for the procedure for the fire receiver 1 to store the first address information and the second address information in the first storage unit 11. explain. In the following description, the three fire detectors 2 are also referred to as fire detectors 2a, 2b, and 2c. AD11, AD12, and AD13 are assigned to the fire detectors 2a, 2b, and 2c as second address information, respectively.

When the third communication unit 33 of the repeater 3 becomes communicable with the first communication unit 14 of the fire receiver 1 after the activation of the second control unit 34 of the repeater 3 is completed, the first of the fire receiver 1 The first address information is transmitted to the communication unit 14 (P1). The second control unit 34 also receives a signal requesting the first address information from the first communication unit 14 of the fire receiver 1, for example, when the second control unit 34 receives a signal requesting the first address information from the first communication unit 14 of the fire receiver 1. 1 Send address information.

The first control unit 15 of the fire receiver 1 stores the first address information received by the first communication unit 14 in the first storage unit 11 (P2). Table 1 below shows the storage state of the first storage unit 11 when the first address information and the second address information are not registered in the first storage unit 11. On the other hand, Table 2 shows the storage state of the first storage unit 11 after the first control unit 15 stores the first address information in the first storage unit 11. In Table 2, "AD10" is stored in the first storage unit 11 as the address of the repeater 3. The first address information is not limited to being transmitted by the third communication unit 33 of the repeater 3, and the operator operates the operation unit 13 of the fire receiver 1 to store the first address information in the first storage unit 11. You may memorize it in.

The first control unit 15 transmits the first request signal to the third communication unit 33 of the repeater 3 to which the AD10 is assigned as the address (P3). The first request signal is a signal that requests the repeater 3 for all the address information of the plurality of fire detectors 2 connected to the repeater 3.

When the third communication unit 33 receives the first request signal, the second control unit 34 of the repeater 3 transmits the second request signal from the second communication unit 32 to the fourth communication unit 21 of the plurality of fire detectors 2. (P4). The second request signal is a signal that requests each fire detector 2 for the second address information assigned to each fire detector 2.

When the fourth communication unit 21 of each fire detector 2 receives the second request signal, the third control unit 22 is stored in the third storage unit 23 in the time slot assigned to each fire detector 2. The second address information is transmitted from the fourth communication unit 21 to the second communication unit 32 of the repeater 3 (P5).

When the second communication unit 32 of the repeater 3 receives the second address information, the second control unit of the repeater 3 stores the received second address information in the second storage unit 31. It should be noted that the configuration in which the second control unit 34 stores the second address information in the second storage unit 31 when the second communication unit 32 receives the second address information is not an essential configuration, and the second control unit 34 is not an essential configuration. May hold the second address information in the memory of the microcomputer or the like.

When the second control unit 34 receives a plurality of second address information from all of the plurality of fire detectors 2, it generates a first response signal, and the first response signal is transmitted from the third communication unit 33 to the fire receiver 1. It is transmitted to the first communication unit 14 (P6). The first response signal is a signal that responds to the first request signal, and is a signal that includes a plurality of second address information corresponding to all the fire detectors 2 that can communicate with the repeater 3.

Here, as a method of determining whether or not the second control unit 34 has received the plurality of second address information from all of the plurality of fire detectors 2, for example, the second communication unit 32 transmits the first request signal. There is a method to use the elapsed time from the time when it was done. The second control unit 34 sets the waiting time as a waiting time determined by the product of the number of fire detectors 2 connectable to the repeater 3 and the length of the time slot assigned to each fire detector 2. The second control unit 34 uses the plurality of second address information received from the time when the first request signal is transmitted to the time when the waiting time elapses to the plurality of second address information corresponding to all the fire detectors 2. Judge that.

When the first communication unit 14 of the fire receiver 1 receives the first response signal, the first control unit 15 of the fire receiver 1 acquires a plurality of second address information included in the first response signal. The first control unit 15 causes the display unit 12 to display each of the acquired second address information (P7). The operator can confirm the display contents of the display unit 12 and perform the management operation of the second address information (P8). For example, the operator compares the display content of the display unit 12 with each fire detector 2 actually connected to the repeater 3, and if the display content is correct, operates the operation unit 13 to perform each operation. 2 The address information is stored in the first storage unit 11. On the other hand, if the display content of the display unit 12 is not correct, the operator can operate the operation unit 13 to cancel the storage of each second address information in the first storage unit 11. When the operator operates the operation unit 13 to store the plurality of second address information in the first storage unit 11, the storage (registration) of the second dress information in the first storage unit 11 is completed (P9). .. The first address information and the plurality of second address information stored in the first storage unit 11 are stored information. As a result, the repeater 3 of the fire detection system 5 and the plurality of fire detectors 2 are registered in the fire receiver 1. Table 3 shows the storage state of the first storage unit 11 when the first address information of the repeater 3 and the second address information of the fire detectors 2a, 2b, and 2c are stored as stored information.

Here, the first control unit 15 associates the first address information of the repeater 3, which is the source of the first response signal, with the plurality of second address information included in the first response signal, and first stores the information. It is stored in the part 11. As an example, the first control unit 15 manages the stored information by setting each second address information and the first address information of the repeater 3 which is the source of each second address information as one set. In other words, the first control unit 15 manages a plurality of second address information for each of the first address information of the repeater 3.

For example, when the second address information is changed due to the replacement of the fire detector 2b in the disaster prevention system 100, the first control unit 15 is the repeater 3 to which the replaced fire detector 2b is connected. Only the plurality of second address information associated with the first address needs to be updated. Therefore, the first control unit 15 can update the second address information of the exchanged fire detector 2b without reacquiring all the second address information of the disaster prevention system 100. Further, even if the second address information of the replaced fire detector 2b is unknown, the second address information of the fire detector 2b can be obtained from the repeater 3, so that the fire detector 2b is replaced after the fire detector 2b is replaced. It is possible to save the trouble of storing the second address information of the above in the first storage unit 11.

Next, a case where the second address information of the fire detector 2b changes from AD12 to AD14 when one fire detector 2b is replaced due to a failure of the fire detector 2b will be described.

The operator operates the operation unit 13 of the fire receiver 1 to transmit the first request signal from the first communication unit 14 of the fire receiver 1 to the third communication unit 33 of the repeater 3. The first control unit 15 of the fire receiver 1 compares the acquired information with the stored information. Table 4 shows the acquired information.

The first control unit 15 compares, for example, the acquired information shown in Table 4 with the stored information shown in Table 3, and determines that the second address information of the fire detector 2b has been changed from AD12 to AD14. .. Then, the first control unit 15 causes the display unit 12 to display the second address information of the changed fire detector 2. The operator can compare the display content of the display unit 12 with the changed second address information of the fire detector 2b and confirm that the fire detector 2b has been replaced. In the above example, the second address information of the fire detector 2b to be replaced and the second address information of the fire detector 2b after replacement are different, but the present invention is not limited to this, and the fire detector 2b is not limited to this. The same second address information may be used before and after the exchange. In that case, the worker replaces the fire detector 2 by confirming on the display that the second address information of the fire detector 2b can communicate with the repeater 3 without being changed. You can confirm that.

(6) Procedure for Discarding First and Second Address Information A procedure for the fire receiver 1 to discard the first address information and the second address information from the first storage unit 11 will be described with reference to FIG. In the following, a case will be described in which the repeater 3 capable of communicating with the fire receiver 1 is removed from the first communication line L1 to disconnect the repeater 3 and the fire receiver 1 as an example.

Before removing the repeater 3 from the first communication line L1, the operator operates the operation unit 13 of the fire receiver 1 to send the third request signal from the first communication unit 14 of the fire receiver 1 to the repeater 3. (P21). The third request signal is a signal that requests the repeater 3 to discard the plurality of second address information stored in the second storage unit 31 of the repeater 3. When the third communication unit 33 of the repeater 3 receives the third request signal, the second control unit 34 of the repeater 3 discards the plurality of second address information stored in the second storage unit 31 (P22). ). The second control unit 34 causes the third communication unit 33 to transmit the third response signal to the first communication unit 14 of the fire receiver 1 after discarding the plurality of second address information from the second storage unit 31 (P23). ).

When the first communication unit 14 receives the third response signal, the first control unit 15 of the fire receiver 1 receives the first address information assigned to the repeater 3 to which the third response signal is transmitted, and the first address information thereof. Both the plurality of second address information associated with the address information and the second address information are discarded (P24). This prevents the second address information of the fire detector 2, which cannot communicate with the fire receiver 1, from remaining in the first storage unit 11. After that, the operator removes the repeater 3 from the first communication line L1 (P25).

Next, refer to FIG. 5 for a procedure in which the fire receiver 1 discards the first address information and the second address information from the first storage unit 11 when the fire receiver 1 and the repeater 3 cannot communicate with each other. I will explain. The case where the fire receiver 1 and the repeater 3 cannot communicate is, for example, a case where the operator removes the repeater 3 from the first communication line L1.

The operator removes the repeater 3 from the first communication line L1 (P31). The first control unit 15 of the fire receiver 1 transmits a fourth request signal to the third communication unit 33 of the repeater 3 (P32). The fourth request signal is, for example, a signal for alive check, which is a signal transmitted from the first communication unit 14 to the third communication unit 33 of the repeater 3 in response to the operation of the operation unit 13 of the fire receiver 1. be. The fourth request signal may be periodically (for example, every 24 hours) transmitted from the first communication unit 14 to the third communication unit 33 of the repeater 3 without input operation to the operation unit 13.

When the first communication unit 14 receives the fourth response signal between the time when the first communication unit 14 transmits the fourth response signal and the time when a predetermined time elapses, the first control unit 15 makes a fourth request. It is determined that communication with the repeater 3 of the signal transmission destination is possible. On the other hand, if the first control unit 15 cannot receive the fourth response signal between the time when the first communication unit 14 transmits the fourth response signal and the time when a predetermined time elapses, the first control unit 15 determines that the time-out has occurred. Then, it is determined that the repeater 3 at the transmission destination of the fourth request signal cannot be communicated (P33).

When the first control unit 15 determines that it cannot communicate with the repeater 3 of the transmission destination of the fourth request signal, the first address information of the transmission destination of the fourth request signal and a plurality of associated with the first address information. The second address information of the above is displayed on the display unit 12 (P34). The operator confirms that the first address information of the repeater 3 removed from the first communication line L1 and the first address information displayed on the display unit 12 match, and the first address information and a plurality of the first address information. The operation of deleting the second address information of the above is input to the operation unit 13 (P35). The first control unit 15 obtains the first address information of the transmission destination of the fourth request signal and the plurality of second address information associated with the first address information according to the operation input to the operation unit 13. Discard from the first storage unit 11 (P36).

By the way, steps P34 and P35 may be executed after step P36. For example, when the first control unit 15 determines that it cannot communicate with the repeater 3 to which the fourth request signal is transmitted, the first control unit 15 discards the stored information, and then causes the display unit 12 to display the discard of the stored information. Then, the operator may wait for an input operation to the operation unit 13. Alternatively, for example, steps P34 and P35 may be omitted. As a result, in the fire receiver 1, for example, when the repeater 3 is removed from the first communication line L1 and the first address information of the repeater 3 is deleted from the first storage unit 11, the first address is deleted. A plurality of second address information corresponding to the information will be automatically discarded.

By the way, the first storage unit 11 of the fire receiver 1 can store the first address information by operating the operation unit 13 of the fire receiver 1. For example, even in the repeater 3 which does not have the function of transmitting the first address information to the fire receiver 1, the operator operates the operation unit 13 and uses the first address information assigned to the repeater 3 as the first address information. By storing in 1 storage unit 11, the repeater 3 and the fire receiver 1 can communicate with each other. However, in this case, if the operator inputs erroneous first address information to the operation unit 13, the erroneous first address information will be stored in the first storage unit 11. Therefore, when the first address information is stored in the first storage unit 11, the first control unit 15 of the fire receiver 1 is assigned the stored first address information to the third communication unit 33 of the repeater 3. A confirmation signal is transmitted to, and it is determined whether or not communication with the third communication unit 33 is possible. When the first communication unit 14 can receive the response signal to the confirmation signal between the time when the confirmation signal is transmitted and the time when the predetermined time elapses, the first control unit 15 has the first communication unit 14 to the first. 3 The first request signal can be transmitted to the communication unit 33.

On the other hand, the first control unit 15 can receive the response signal corresponding to the confirmation signal from the time when the first communication unit 14 transmits the confirmation signal to the time when a predetermined time elapses. If not, the first address information is discarded from the first storage unit 11. Then, the first control unit 15 causes the display unit 12 to display that the first address information has been discarded from the first storage unit 11. As a result, the first address erroneously stored in the first storage unit 11 is discarded from the first storage unit 11. Further, the operator can know from the display contents of the display unit 12 that the first address information erroneously input has been discarded from the first storage unit 11.

The repeater 3 acquires and holds a plurality of second address information from the plurality of fire detectors 2, and when receiving a request signal, transmits the held plurality of second address information to the fire receiver 1. It is configured in.

The repeater 3 of the disaster prevention system according to the modified example will be described. The second control unit 34 of the repeater 3 acquires a plurality of second address information from the plurality of fire detectors 2 and stores them in the second storage unit 31 before the third communication unit 33 receives the first request signal. doing. The second control unit 34 of the repeater 3 causes, for example, the second communication unit 32 to periodically (for example, every two hours) transmit the second request signal to the plurality of fire detectors 2 to transmit the second request signal to the plurality of fire detectors. A plurality of second address information is acquired from 2, and a plurality of second address information is stored in the second storage unit 31. In other words, the repeater 3 can acquire and hold a plurality of second address information from the plurality of fire detectors 2.

When the third communication unit 33 receives the first request signal, the second control unit 34 generates a first response signal including a plurality of second address information stored in the second storage unit 31, and the third communication unit 34 generates a first response signal. The first response signal is transmitted from the unit 33 to the fire receiver 1. That is, the repeater 3 in the disaster prevention system according to the modified example is stored in the second storage unit 31 without acquiring a plurality of second addresses from the plurality of fire detectors even if the first request signal is received. A first response signal including a plurality of second address information is transmitted to the fire receiver.

According to the above configuration, between the time when the fire receiver 1 transmits the first request signal and the time when the first response signal is received, the repeater 3 receives the plurality of second address information from the plurality of fire detectors 2. No need for time to get. Therefore, the time from the time when the fire receiver 1 transmits the first request signal to the time when the first response signal is received is shortened.

Since the other configurations of the disaster prevention system 100 according to the modified example are the same as those of the disaster prevention system 100 of the first embodiment, the description thereof will be omitted.

(Embodiment 2)
The disaster prevention system 100 of the second embodiment will be described. The disaster prevention system 100 of the second embodiment is different from the disaster prevention system 100 of the first embodiment in that the repeater 3 compares the second address information instead of the fire receiver 1 comparing the second address information. In the disaster prevention system 100 of the second embodiment, the same components as those of the disaster prevention system 100 of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In the disaster prevention system 100 of the second embodiment, the storage unit of the fire receiver 1 is the first storage unit 11. The repeater 3 has a second storage unit 31 that stores a plurality of second address information. The repeater 3 compares the plurality of second address information stored in the second storage unit 31 with the plurality of second address information acquired from the plurality of fire detectors 2, and the comparison result is obtained as a fire receiver.
