[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] First, combine Figure 1 and Figure 2 The wiring structure of the fire protection system is explained.

[0027] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the tree topology provided by the relevant technology. When the fire protection system line is long, it is usually used as follows Figure 1 The tree topology structure shown. The tree topology structure includes line 1 and line 2. Line 1 is the line starting from the upper interface of the main control board, and line 2 is the line starting from the lower interface of the main control board. Each line is mounted with fire peripherals 1-N, and isolation module 1 is connected in series between the main control board and fire peripheral 1, and isolation module 2 is connected in series between fire peripheral K and fire peripheral K+1.

[0028] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the ring topology provided by the relevant technology. When the line of the fire protection system is short, it is usually used as follows Figure 2The ring topology shown. The ring topology includes a ring line, line 1 is defined as a ring line starting from the upper interface of the main control board, and line 2 is defined as a ring line starting from the lower interface of the main control board. The ring line mounts fire peripherals 1-N, isolation module 1 is connected in series between the upper interface of the main control board and fire peripheral 1, isolation module 2 is connected in series between fire peripheral K and fire peripheral K+1, isolation module 3 is connected in series between fire peripheral M and fire peripheral M+1, isolation module 4 is connected in series between fire peripheral P and fire peripheral P+1, and isolation module 5 is connected in series between fire peripheral N and the lower interface of the main control board.

[0029] Among them, the main control board: can be a first-in-first-out bus (FBUS) main control board. For the tree topology, line 1 and line 2 are respectively connected to the isolation module and the fire peripheral, and the two lines are independent of each other; for the ring topology, line 1 and line 2 send inspection pulses to the fire peripheral and isolation module in clockwise and counterclockwise directions respectively to obtain the operating status of each module.

[0030] Isolation module: It can detect whether the lines before and after the isolation module are short-circuited, cut off the corresponding line part according to the location of the short circuit, and report the short circuit information to the main control board.

[0031] Fire protection peripherals: mainly include temperature sensing module, smoke sensing module, manual alarm module, fire hydrant module, alarm module, broadcast module, etc.

[0032] Temperature sensing module: It can detect the current ambient temperature. If it exceeds the threshold, it will send a high temperature alarm to the main control board.

[0033] Smoke sensor module: It can detect the current smoke concentration in the environment. If it exceeds the threshold, it will send a high smoke concentration alarm to the main control board.

[0034] Manual alarm module: requires manual triggering, and when pressed, a fire alarm is sent to the main control board.

[0035] Alarm module: After the main control board receives the alarm sent by other sensors, it controls the alarm module to light up the alarm light to remind people that there is a fire.

[0036] Broadcast module: After the main control board receives the alarm sent by other sensors, it controls the broadcast module to broadcast and remind people that there is a fire.

[0037] It should be noted that Figure 1 and Figure 2 This is only used as an example. In actual applications, the total number of isolation modules and fire protection peripherals is about 220, and an isolation module must be installed for every interval of no more than 30 fire protection peripherals.

[0038] Next, combine the following Figure 3 and Figure 4 The fire protection system line fault detection method of the present invention is described.

[0039] Please refer to Figure 3 , Figure 3 FIG. 1 is a flow chart of a fire protection system line fault detection method provided by an embodiment of the present invention. Figure 3 As shown, the method may include step 301 and step 302.

[0040] Step 301, when a fire protection system line fails, the inspection pulse return code of each fire protection peripheral mounted on the fire protection system line is used to detect whether a peripheral communication failure occurs in each fire protection peripheral, and the main control board of the fire protection system and the isolation module on the line are used to detect whether a line short circuit occurs in each fire protection peripheral.

[0041] Specifically, when a fire protection system line fails, it is possible to detect whether the inspection pulse return code of each fire protection peripheral mounted on the fire protection system line is correct, thereby detecting whether a peripheral communication failure occurs in each fire protection peripheral. At the same time, the main control board of the fire protection system and the isolation module on the line detect whether the front and rear lines are short-circuited, thereby detecting whether a line short-circuit failure occurs in each fire protection peripheral.

[0042] In one embodiment, if Figure 4 As shown, the method for detecting a peripheral device communication failure may include steps 401 to 410.

[0043] Step 401, initialize the peripheral communication failure count array.

[0044] Specifically, a peripheral communication failure count array is set, and the peripheral communication failure count array is used to record the number of peripheral communication failures corresponding to each address, and the initial value is 0.

[0045] Step 402: Send inspection pulses address by address through the main control board in the fire protection system.

[0046] Specifically, each fire protection peripheral has a unique address. By sending inspection pulses to each address through the main control board in the fire protection system, the status information of the corresponding fire protection peripheral can be obtained.

[0047] Step 403: Receive the inspection pulse return code returned by the fire protection peripherals corresponding to each address.

[0048] Specifically, after the inspection pulse is sent to each address by the main control board in the fire protection system, the fire protection peripheral device at the corresponding address will return the inspection pulse return code, which carries the status information of the fire protection peripheral device at the corresponding address. Each inspection pulse return code is received by the main control board.

[0049] Step 404: Perform parity check and sum check on each patrol pulse return code to determine whether each patrol pulse return code is correct.

[0050] Step 405 , for each address, determine whether the inspection pulse return code returned by the fire protection peripheral device corresponding to the address is incorrect or whether no inspection pulse return code is returned. If so, proceed to step 406 , if not, proceed to step 409 .

[0051] Step 406: Increase the number of peripheral communication failures corresponding to the address in the peripheral communication failure count array by one.

[0052] Step 407 , determine whether the number of peripheral communication failures corresponding to the address has reached a preset number, if so, proceed to step 408 , if not, return to step 402 .

[0053] Step 408 , reporting that the fire protection peripheral device corresponding to the address has a communication failure, and returning to step 402 .

[0054] Step 409 , clear the number of peripheral communication failures corresponding to the address in the peripheral communication failure count array, and return to step 402 .

[0055] In this embodiment, the inspection pulse is sent to each address by the main control board in the fire protection system, and the inspection pulse return code returned by the fire protection peripheral corresponding to each address is received. The parity check and sum check are performed on each inspection pulse return code, so as to quickly determine whether each inspection pulse return code is correct. For the address where the returned inspection pulse return code is incorrect or no inspection pulse return code is returned, the number of peripheral communication failures corresponding to the address in the peripheral communication failure count array is increased by one, otherwise it is cleared. The number of peripheral communication failures corresponding to each address is recorded by the peripheral communication failure count array, thereby realizing high-efficiency and high-accuracy peripheral communication failure detection with short response time.

[0056] Optionally, the line structure of the fire protection system is a tree topology structure. For each address, if the number of peripheral communication failures corresponding to the address in the peripheral communication failure count array is greater than the preset number, it is determined that the fire protection peripheral corresponding to the address has a peripheral communication failure; if the inspection pulse return code is incorrect and the number of peripheral communication failures corresponding to the address in the peripheral communication failure count array is less than the preset number, the number of peripheral communication failures corresponding to the address in the peripheral communication failure count array is increased by one, and the inspection of the fire protection peripheral corresponding to the next address is continued; if the inspection pulse return code is correct, the number of peripheral communication failures corresponding to the address in the peripheral communication failure count array is cleared to zero, and the inspection of the fire protection peripheral corresponding to the next address is continued. The preset number can be 5, and the present embodiment is not limited to this. In this way, for the tree topology structure, the fault type of the peripheral communication failure and the location where the peripheral communication failure occurs can be quickly and accurately located.

[0057] Optionally, the line structure of the fire protection system is a ring topology structure, and the two interfaces of the main control board each correspond to a peripheral communication failure count array. The first peripheral communication failure count array is used to record the number of peripheral communication failures corresponding to each address obtained by patrolling the upper interface of the main control board clockwise one by one, and the second peripheral communication failure count array is used to record the number of peripheral communication failures corresponding to each address obtained by patrolling the lower interface of the main control board counterclockwise one by one. For each address in each peripheral communication failure count array, if the number of peripheral communication failures corresponding to the address in the peripheral communication failure count array is greater than the preset number, it is determined that a peripheral communication failure occurs in the fire peripheral corresponding to the address on the line corresponding to the peripheral communication failure count array; if the inspection pulse return code on the line corresponding to the peripheral communication failure count array is incorrect, and the number of peripheral communication failures corresponding to the address in the peripheral communication failure count array is less than the preset number, then the number of peripheral communication failures corresponding to the address in the peripheral communication failure count array is increased by one, and the inspection of the fire peripheral corresponding to the next address is continued; if the inspection pulse return code on the line corresponding to the peripheral communication failure count array is correct, then the number of peripheral communication failures corresponding to the address in the peripheral communication failure count array is cleared, and the inspection of the fire peripheral corresponding to the next address is continued. The preset number can be 5, and the present embodiment is not limited to this. In this way, for a ring topology structure, the fault type of the peripheral communication failure and the location where the peripheral communication failure occurs can be quickly and accurately located.

[0058] Optionally, the detection of whether a line short circuit fault occurs in each fire protection peripheral device through the main control board of the fire protection system and the isolation module on the line in step 301 includes: determining the line structure of the fire protection system, and determining the isolation module that detects the line short circuit fault based on the line structure of the fire protection system; cutting off the relay inside the determined isolation module, and reporting the line short circuit fault to the main control board to determine the location where the line short circuit fault occurs; within the first preset time length, closing the relay inside the determined isolation module every second preset time length, if the determined isolation module does not detect the line short circuit fault, keeping the relay inside the determined isolation module closed, otherwise cutting off the relay inside the determined isolation module. In this way, the fault type of line short circuit fault and the location where the line short circuit fault occurs can be quickly and accurately located, and the line can be attempted to be restored when a line short circuit fault occurs, thereby improving the reliability and safety of the fire protection system.

[0059] The following is a specific description of the line short circuit fault detection scheme using two different fire protection system line structures.

[0060] In one embodiment, the line structure of the fire protection system is a tree topology structure; the main control board of the fire protection system and the isolation module on the line detect whether a line short circuit fault occurs in each fire protection peripheral device, including: if the target isolation module detects a line short circuit fault, the relay inside the target isolation module is cut off, and the line short circuit fault is reported to the main control board to determine that the location of the line short circuit fault is the section where the fire protection peripheral devices on the back-end line of the target isolation module are located; within a first preset time length, the relay inside the target isolation module is closed at intervals of a second preset time length, and if the target isolation module does not detect a line short circuit fault, the relay inside the target isolation module is kept closed, otherwise the relay inside the target isolation module is cut off.

[0061] For example, Figure 1 As shown, for a tree topology, if a short circuit occurs in the line between the fire peripheral N and the fire peripheral N-1 on line 1, the nearest isolation module 2 will detect the line short circuit fault and cut off the relay inside the isolation module 2, thereby cutting off the section between the fire peripheral K+1 and the fire peripheral N, and reporting the line short circuit fault to the main control board. The main control board determines that the location where the line short circuit fault occurs is the section between the fire peripheral K+1 and the fire peripheral N on the back-end line of the isolation module 2, and determines the actual short circuit location based on the peripheral information registered in advance on the main control board and the actual peripheral installation location. Within the first preset time (for example, 1 minute), the relay inside the isolation module 2 is closed every second preset time (for example, 10 seconds). If the isolation module 2 does not detect the line short circuit fault, it means that the line has returned to normal, and the relay inside the isolation module 2 is kept closed. Otherwise, the relay inside the isolation module 2 is cut off. If the line has not returned to normal after the first preset time, no automatic recovery will be attempted. At the same time, after a period of time, the main control board will report a peripheral communication failure in the section between fire peripheral K+1 and fire peripheral N. This is because the isolation module 2 cuts off the section between fire peripheral K+1 and fire peripheral N, and the main control board cannot receive the correct inspection pulse return code when inspecting the fire peripherals (the inspection pulse return code is incorrect or the inspection pulse return code is not returned).

[0062] In this embodiment, for the tree topology, if the target isolation module detects a line short-circuit fault, the relay inside the target isolation module is cut off, and the line short-circuit fault is reported to the main control board to determine that the location where the line short-circuit fault occurs is the section where the fire protection peripherals on the back-end line of the target isolation module are located, and the fault type can be quickly and accurately located as a line short-circuit fault and the location where the line short-circuit fault occurs. Within the first preset time length, the relay inside the target isolation module is closed at intervals of the second preset time length. If the target isolation module does not detect a line short-circuit fault, the relay inside the target isolation module is kept closed, otherwise the relay inside the target isolation module is cut off, and the line can be restored when a line short-circuit fault occurs, thereby improving the reliability and safety of the fire protection system.

[0063] In another embodiment, the line structure of the fire protection system is a ring topology structure; the main control board of the fire protection system and the isolation module on the line detect whether a line short circuit fault occurs in each fire protection peripheral device, including: if the first isolation module and the second isolation module both detect a line short circuit fault, the relays inside the first isolation module and the second isolation module are cut off, and the line short circuit fault is reported to the main control board to determine that the location where the line short circuit fault occurs is the section where the fire protection peripheral devices are located between the first isolation module and the second isolation module; within a first preset time length, the relays inside the first isolation module and the second isolation module are closed at intervals of a second preset time length; if the first isolation module and the second isolation module do not detect a line short circuit fault, the relays inside the first isolation module and the second isolation module are kept closed, otherwise the relays inside the first isolation module and the second isolation module are cut off.

[0064] For example, Figure 2As shown, for the ring topology, if a line short circuit fault occurs between the upper fire peripheral K+1 and the fire peripheral M of the ring line, then the isolation module 2 and the isolation module 3 both detect the line short circuit fault, cut off the relays inside the isolation module 2 and the isolation module 3, and report the line short circuit fault to the main control board. The main control board determines that the location where the line short circuit fault occurs is the section between the fire peripheral K+1 and the fire peripheral M between the isolation module 2 and the isolation module 3, and determines the actual short circuit location according to the peripheral information registered in advance on the main control board and the actual peripheral installation position. Within the first preset time (for example, 1 minute), the relays inside the isolation module 2 and the isolation module 3 are closed at intervals of the second preset time (for example, 10 seconds). If the isolation module 2 and the isolation module 3 do not detect the line short circuit fault, it means that the line has returned to normal, and the relays inside the isolation module 2 and the isolation module 3 are kept closed. Otherwise, the relays inside the isolation module 2 and the isolation module 3 are cut off. If the line has not returned to normal after the first preset time, no automatic recovery will be attempted. At the same time, after a period of time, the main control board will report that a peripheral communication failure occurs in the section between fire peripheral K+1 and fire peripheral M. This is because isolation module 2 and isolation module 3 cut off the section between fire peripheral K+1 and fire peripheral N. The main control board cannot receive the correct inspection pulse return code when inspecting the fire peripherals (the inspection pulse return code is incorrect or the inspection pulse return code is not returned).

[0065] In this embodiment, for the ring topology, if both the first isolation module and the second isolation module detect a line short circuit fault, the relays inside the first isolation module and the second isolation module are cut off, and the line short circuit fault is reported to the main control board to determine that the location where the line short circuit fault occurs is the section where the fire protection peripherals are located between the first isolation module and the second isolation module, and the fault type can be quickly and accurately located as a line short circuit fault and the location where the line short circuit fault occurs. Within the first preset time length, the relays inside the first isolation module and the second isolation module are closed at intervals of the second preset time length. If the first isolation module and the second isolation module do not detect a line short circuit fault, the relays inside the first isolation module and the second isolation module are kept closed, otherwise the relays inside the first isolation module and the second isolation module are cut off, and the line can be restored when a line short circuit fault occurs, thereby improving the reliability and safety of the fire protection system.

[0066] Step 302: When a peripheral communication failure is detected in the fire protection peripheral, detect whether an open circuit failure occurs in the line of the fire protection system.

[0067] Specifically, when a peripheral communication failure of the fire protection peripheral is detected, it is detected whether an open circuit failure occurs in the line of the fire protection system according to the situation of the peripheral communication failure.

[0068] Optionally, step 302 includes: when a peripheral communication failure of a fire protection peripheral is detected, determining the line structure of the fire protection system; based on the line structure of the fire protection system, selectively determining the line open circuit failure of the line of the fire protection system and the location where the line open circuit failure occurs according to the addresses or total number of multiple fire protection peripherals with peripheral communication failures. In this way, the fault type of the line open circuit failure and the location where the line open circuit failure occurs can be quickly and accurately located.

[0069] The following is a specific description of the line open circuit fault detection scheme using two different fire protection system line structures.

[0070] In one embodiment, the line structure of the fire protection system is a tree topology structure, and step 302 includes: when a peripheral communication failure is detected in multiple fire protection peripherals, if the addresses of the multiple fire protection peripherals are continuous and include the end address of the line, it is determined that the line of the fire protection system has an open circuit failure and the location of the open circuit failure.

[0071] For example, Figure 1 As shown, for a tree topology structure, when a peripheral communication failure is detected in multiple fire peripherals, if multiple addresses corresponding to the peripheral communication failure are continuous and include the address at the end of the line, it is determined that a line open circuit failure occurs in the line of the fire protection system. For example: fire peripherals K+1 to fire peripherals N on line 1 report a peripheral communication failure, and the fire peripherals before fire peripherals K+1 do not report a peripheral communication failure. Since the addresses of fire peripherals K+1 to fire peripherals N are continuous and the address of fire peripherals N is the address at the end of the line, it is considered that line 1 has a line open circuit failure. The location where the line open circuit failure occurs is the section between isolation module 2 and fire peripherals K+1. The actual open circuit location is determined based on the peripheral information registered in advance on the main control board and the actual peripheral installation location. If fire peripherals 1 to fire peripherals K report a peripheral communication failure, and other fire peripherals do not report a communication failure, since they do not include the address at the end of the line, the line is not open.

[0072] In this embodiment, for the tree topology structure, when peripheral communication failures are detected in multiple fire protection peripherals, if the addresses of the multiple fire protection peripherals are continuous and include the end address of the line, then it is determined that the line of the fire protection system has an open circuit failure and the location where the open circuit failure occurs, and the fault type of the open circuit failure and the location where the open circuit failure occurs can be quickly and accurately located.

[0073] In another embodiment, the line structure of the fire protection system is a ring topology structure, and step 302 includes: when both interfaces of the main control board detect that a peripheral communication failure occurs in the fire protection peripheral, if the total number of fire protection peripherals with peripheral communication failures detected by the two interfaces of the main control board is equal to the total number of fire protection peripherals mounted in the ring topology structure, then it is determined that an open circuit failure occurs in the line of the fire protection system and the location where the open circuit failure occurs.

[0074] For example, Figure 2 As shown, for the ring topology structure, when both interfaces of the main control board detect that a peripheral communication failure occurs in the fire peripheral, line 1 reports that a peripheral communication failure occurs in all fire peripherals between the isolation module 3 and the isolation module 5, and line 2 reports that a peripheral communication failure occurs in all fire peripherals between the isolation module 1 and the fire peripheral M. It is then considered that an open circuit fault occurs in the ring topology structure, and the location of the open circuit fault is the section between the fire peripheral M and the isolation module 3. The actual open circuit location is determined based on the peripheral information registered in advance on the main control board and the actual peripheral installation location.

[0075] In this embodiment, for the ring topology structure, when both interfaces of the main control board detect that a peripheral communication failure occurs in the fire protection peripherals, if the total number of fire protection peripherals with peripheral communication failures detected by the two interfaces of the main control board is equal to the total number of fire protection peripherals mounted in the ring topology structure, then it is determined that the line of the fire protection system has an open circuit failure and the location where the open circuit failure occurs, and the fault type of the open circuit failure and the location where the open circuit failure occurs can be quickly and accurately located.

[0076] In summary, the fire protection system line fault detection method provided by the embodiment of the present invention, first, when the line of the fire protection system fails, the inspection pulse return code of each fire protection peripheral mounted on the line of the fire protection system is used to detect whether a peripheral communication failure occurs in each fire protection peripheral, and the isolation module on the main control board of the fire protection system and the line is used to detect whether a line short circuit failure occurs in each fire protection peripheral; then, when a peripheral communication failure is detected in the fire protection peripheral, the line of the fire protection system is detected to detect whether an open circuit failure occurs, which can quickly and accurately locate the fault type and the fault location, and reduce the manpower and time cost generated by the inspection line. The embodiment of the present invention can achieve high-efficiency and high-accuracy fault detection, with a short response time, and significantly improve the reliability of the fire protection system.

[0077] Furthermore, since the place where the fire-fighting peripherals are installed is a place that is not easily touched, the embodiments of the present invention also help to reduce the safety risks of maintenance personnel.
