Description

Technical Field

[0001] The utility model relates to the detection of a fire alarm system for EMUs, and is mainly applied to the technical field of maintenance of EMU service equipment. Background Technique

[0002] The smoke and fire alarm system of EMUs mainly consists of a smoke and fire alarm host and smoke detectors, and can collect smoke and temperature data of fire hazard parts such as EMU passenger compartments, electrical cabinets, PIS cabinets, and toilets in real time. As an important part of the safety loop of EMUs, this system can monitor the fire alarm status of each position in a timely manner and ensure the safe and stable operation of EMUs. However, with the continuous increase in the number of EMUs in service and the operating years, the following problems have emerged in the smoke and fire alarm system:

[0003] (1) False alarms occur frequently. False alarms caused by dust or water-based sprays will lead to the speed reduction or even emergency stop of EMUs, seriously affecting the normal operation order;

[0004] (2) Lack of relevant detection technology equipment. There are problems such as diverse EMU platforms, complex detector models, and different system compatibilities in the smoke and fire alarm system. For CRH1, CRH2, CRH3, and CR400 EMUs, the architectures of their smoke and fire alarm systems are different, and they often do not have universality in terms of electrical and mechanical interfaces. The conventional spray detection method is single, and false detection may occur;

[0005] (3) Low maintenance efficiency. The maintenance of faulty components requires the occupation of in-service vehicle resources, which restricts the maintenance efficiency of EMUs.

[0006] Based on the above requirements, a detection platform for the fire alarm system of EMUs is developed. Summary of the Invention

[0025] Preferably, the above-mentioned monitoring unit (2) includes a temperature sensor (9) and a smoke sensor (14). The temperature sensor (9) and the smoke sensor (14) are installed inside the circulation flue (8), connected to the industrial control computer (10), and return the detected temperature data and smoke concentration data to the industrial control computer (10).

[0026] Preferably, the above-mentioned smoke and fire alarm system (3) includes a smoke and fire alarm host (6) and a smoke detector (7). Among them, the smoke detector (7) includes a single-light source detector and a double-light source detector, is installed in the circulation flue (8), and is connected to the smoke and fire alarm host (6). The smoke and fire alarm host (6) includes a smoke and fire alarm host for 380D-type multiple unit trains, 380B-type multiple unit trains, and 400BF-type multiple unit trains, and is connected to the industrial control computer (10).

[0027] Preferably, the above-mentioned fire simulation unit (4) includes a hot air module (11), a smoke generation module (12), and a smoke collection module (13).

[0028] This detection platform for the smoke and fire alarm system can perform functional tests on the smoke detector and the smoke and fire alarm host. The test procedures for both are the same. Taking the detection of the smoke detector as an example, as Figure 4 shown.

The industrial control computer (10) collects the data of the temperature sensor (9) and the smoke sensor (14) and displays them on the human-machine interaction module (15). After the smoke concentration and temperature reach the alarm threshold, read the information of the smoke alarm host (6). If there is no fire alarm information, it is judged that the smoke detector to be tested is faulty. If a fire alarm is normally displayed, turn off the hot air module (11) and the smoke generation module (12), start the smoke collection module (13) to purify the smoke in the circulation flue (8). Wait until the smoke concentration and temperature return to the indoor environment, read the return information of the smoke alarm host (6). If a fire alarm is displayed, it is judged that the smoke detector to be tested is faulty. If no fire alarm is displayed, it is judged that the smoke detector to be tested is normal, and the test is over.
