Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting equipment maintenance, and in particular to a portable fire-fighting equipment maintenance method and device. Background Art

[0002] The existing fire protection systems are all connected to different fire terminal devices such as fire smoke sensors, temperature sensors, manual alarms, fire alarms, sound and light alarms, input modules, output modules, input and output modules, infrared detectors, etc. in various circuits of the fire control host. Among them, the input modules, output modules and input and output modules are mainly execution equipment control modules, such as water pumps and fans.

[0003] Each fire terminal on the same loop is connected to the loop of the fire control host in parallel through two core wires. Each terminal has its own unique address code to distinguish different terminals. Due to the complex types of on-site terminals, and each terminal may be installed on different floors and different rooms, which are very far away from the fire control host. For one or more terminals that send out fault signals, especially when the fault signal is caused by a line fault, the maintenance process is cumbersome. Therefore, an instrument that can quickly repair the terminal is urgently needed. Summary of the invention

[0004] The object of the present invention is to provide a portable fire-fighting equipment maintenance method and device for use in the maintenance and repair of fire-fighting equipment terminals.

[0005] In order to achieve the above object, the present invention is specifically implemented through the following technical solutions:

[0007] S1. Set a fire terminal that simulates sending a fault signal. The setting information includes the terminal type, manufacturer, model and management address of the fire terminal, and call the communication protocol according to the setting information;

[0008] S2, connect the simulated fire terminal of S1 to the fire line, replace the fire terminal, and wait for the on-site fire control host to send a polling signal to the fire terminal;

[0009] S3. Determine the cause of the fault based on whether the fault signal on the on-site fire control host disappears: if the fault signal of the fire terminal disappears, it is an equipment failure of the fire terminal. Replace the fire terminal and the maintenance is completed; if the fault signal does not disappear, proceed to step S4;

[0010] S4, simulate the fire control host directly connects to the fire terminal that sends the fault signal and sends an inquiry signal. If there is no feedback signal, the fire terminal is faulty, and the fire terminal is replaced and then goes to step S5; if there is a feedback signal, directly go to step S5;

[0011] S5. Match the management address and communication protocol of each fire terminal, set the fire terminal management address range, send an inquiry signal to each fire terminal in the address range, receive the feedback signal of each fire terminal, and determine the fault location according to the feedback signal interruption position line.

[0012] As a further improvement to the above solution, the inquiry signal in step S5 is sent in a polling manner.

[0013] The present invention also provides a portable fire-fighting equipment maintenance device, comprising:

[0014] A wiring unit, used for connecting in parallel the circuits and signal lines near the fire terminal to be detected;

[0015] An input unit, used to set the model data and management address data of the fire terminal to be detected, the model data including the type, manufacturer and model of the fire terminal;

[0016] The storage unit is used to store the terminal type, manufacturer, model and communication protocol data of the fire terminal and the fire control host, and retrieve them according to the input unit settings;

[0020] As a further improvement to the above scheme, the fire-fighting terminals to be detected include smoke sensors, temperature sensors, manual alarms, fire alarms, sound and light alarms, infrared detectors, fans, water pumps or fire-fighting distribution boxes.

[0021] As a further improvement to the above solution, the device comprises a portable box, in which the wiring unit, the input unit, the storage unit, the simulation unit and the processing unit are all installed.

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1 As shown, a portable fire-fighting equipment maintenance method of the present invention includes setting functions for different brands and different communication protocols because the existing fire control host and execution terminal must be of the same brand and matching models.

[0029] Example 1

[0030] A portable fire-fighting equipment maintenance method comprises the following steps:

[0031] S1. Set a fire terminal that simulates sending a fault signal. The setting information includes the terminal type, manufacturer, model and management address of the fire terminal, and call the communication protocol according to the setting information;

[0032] S2, connect the simulated fire terminal of S1 to the fire line, replace the fire terminal, and wait for the on-site fire control host to send a polling signal to the fire terminal;

[0033] S3. Determine the cause of the fault based on whether the fault signal on the on-site fire control host disappears: If the fault signal of the fire terminal disappears, it means that the equipment of the fire terminal is faulty. Replace the fire terminal and the maintenance is completed.

[0034] The method of simulating fire terminals is adopted: the fault is a smoke sensor failure on the first circuit of a certain brand A model. The preliminary judgment is that the smoke sensor is damaged, or a line is disconnected somewhere on the circuit. At this time, it is necessary to set the smoke sensor of the same model of the brand on the maintenance device, and connect the wiring unit of the maintenance device in parallel to the circuit 2 bus. The maintenance device waits for the polling signal from the on-site fire control host according to the established management protocol. If the fault information on the fire control host disappears within one polling cycle of the fire control host, it can be judged that the removed smoke sensor equipment is damaged.

[0035] In Example 1, if the fault signal of the fire terminal that sent the fault signal disappears, it means that the equipment of the fire terminal is faulty. Example 1 is to conduct targeted and separate detection on a certain fire terminal of the fire system in the building. The line connection is convenient and fast, the query signal is highly targeted, and the transmission is fast.

[0036] Example 2

[0037] After the detection in step S3 is completed, if the fault signal has not disappeared, proceed to step S4.

[0038] S4. Set the simulation to the on-site fire control host, match the management address and communication protocol of each fire terminal, simulate the fire control host to directly connect to the fire terminal that sends a fault signal and send an inquiry signal. If there is no feedback signal, the fire terminal is faulty. After replacing the fire terminal, enter step S5; if there is a feedback signal, go directly to step S5.

[0039] If the fault message in Example 1 does not disappear, that is, the fire control host does not prompt that the smoke sensor fault has been restored, the maintenance device is set to simulate the host mode, match the management address and communication protocol of the fire terminal, and send an inquiry signal to the fire terminal to detect whether the fire terminal is faulty. If there is feedback, it can be determined that the fire terminal is not faulty, and the line near the fire terminal is faulty; if there is no feedback, the fire terminal is faulty, and the line is continued to be detected after the fire terminal is replaced.

[0040] Example 3

[0041] After the inspection and judgment of Example 2 is completed, the line fault problem is further detected.

[0042] S5. Match the management address and communication protocol of each fire terminal, set the management address range of the fire terminal, send an inquiry signal to each fire terminal in the address range, receive the feedback signal of each fire terminal, and determine the fault location according to the interruption position of the feedback signal. After determining the fault location of the line, the line can be repaired, and the entire maintenance work is completed.

[0043] At this time, the maintenance device settings can be changed to the same model of fire control host as the fire control room, matching the management address and communication protocol of each fire terminal, and using the simulated host to send inquiry signals to the registered fire terminals configured with each address, and start the simulated fire control host registration polling.

[0044] According to the fire terminal address, set the polling address range of the fault terminal to be detected, and determine between which two terminal devices the line breakpoint is based on the number of polled devices or the polled fire terminal device numbers.

[0045] Preferably, the inquiry signal is sent in a polling manner. The polling signal fully simulates the fire control host signal and can be tested multiple times to avoid occupying the fire control host for maintenance.

[0051] The simulation unit 4 matches the communication protocol of the fire terminal to be detected and the host according to the model data setting of the input unit, and simulates the fire control host to send an inquiry signal to the fire terminal to be detected; or retrieves the communication protocol of the fire terminal to be detected according to the model data of the input unit, simulates the fire terminal to receive the inquiry signal of the on-site fire control host and feeds back;
