[0035] 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.

[0036] Figure 1 This is one of the structural schematic diagrams of the smoke alarm system detection station provided by the embodiment of the present invention.

[0037] like Figure 1 As shown, this embodiment provides a smoke alarm system detection station, including:

[0038] Fire detector detection area and fire detector controller detection area;

[0039] The fire detector detection area includes a sealed box and a smoke generator, the sealed box is connected to the smoke generator through a smoke channel, and a plurality of fire detector installation ports are arranged in the sealed box;

[0040] The fire detector controller detection area is provided with a first fire detector controller access port, a second fire detector controller access port and a plurality of simulated loads, and the simulated loads are used to simulate the state of the fire detector;

[0041] The first fire detector controller access port is used to access the fire detector controller to be tested, and the second fire detector controller access port is used to access the standard fire detector controller, and the simulated load can be connected to the fire detector controller to be tested and the standard fire detector controller at the same time;

[0042] When the simulated load receives the first detection instruction, it simulates different outputs of the fire detector by adjusting the resistance. If the content displayed by the fire detector controller to be tested is consistent with the preset detection standard, it is determined that the fire detector controller to be tested is qualified.

[0043] When the fire detector to be tested is installed in the fire detector installation port and the fire detector controller to be tested passes the detection, the fire detector controller to be tested is connected to the fire detector to be tested through the fire detector installation port, and detects the fire detector to be tested based on the received second detection instruction.

[0044] In actual applications, when the fire detector controller to be tested is tested based on the first detection instruction, the fire detector controller to be tested can be connected to simulated loads in different states. For example, the connected simulated loads can be in an online state and an alarm state. The detection result of the fire detector controller to be tested on the simulated load and the actual state of the simulated load will be sent to the host interface together. If the detection result is consistent with the actual state of the simulated load, it is determined that the fire detector controller to be tested has passed the inspection.

[0045] In practical applications, the sealed box may be transparent on one side so that the inspectors can directly observe the fire detectors in the sealed box.

[0046] In practice, the fire detector to be tested installed in the sealed box can be connected only to the fire detector controller. In this way, data analysis and alarm can be performed on the fire detector to be tested through the connected fire detector controller, thereby enabling more accurate detection of the fire detector to be tested from a data level.

[0047] like Figure 1 As shown, the smoke generator can be arranged at the bottom of the sealed box and transport the smoke upward into the sealed box through the smoke channel.

[0048] The fire detector controller in this embodiment can be set in the central control room of the train in actual application, and is used to remotely monitor whether the fire detectors installed in various places on the train are working normally. In this embodiment, the display screen of the fire detector controller is mainly tested, that is, whether the display screen of the fire detector controller can normally perform the display function is mainly tested. For example, a normal fire detector controller can display through a prompt light and / or text prompt after the connected fire detector generates a smoke alarm. If the fire detector controller fails, it cannot display or cannot display normally. Therefore, a standard fire detector controller is provided in this embodiment. By connecting the fire detector controller to be tested and the standard fire detector controller to a simulated load, when the resistance of the simulated load changes, various working conditions encountered by the fire detector can be simulated. If the display content of the fire detector controller to be tested is consistent with that of the standard fire detector controller or the set detection standard, it means that the fire detector controller to be tested has passed the detection.

[0049] In the smoke alarm system test station provided in the present embodiment, the fire detector controller and the fire detector of the smoke alarm system can be tested at the same time. When testing the fire detector controller, a simulated load can be used to simulate the connected fire detector. Since the resistance value of the simulated load can be precisely controlled, the various working conditions encountered by the fire detector can be accurately simulated. At the same time, the fire detector controller to be tested can be compared with the test standard. The test standard is obtained based on the standard fire detector controller, which can intuitively reflect the quality problems of the fire detector controller. After determining that the fire detector controller to be tested has no quality problems, the fire detector to be tested can be tested based on the fire detector controller. The control terminal can adjust the smoke concentration through the set smoke generator, which can accurately simulate various working conditions of the fire detector. The fire detector can be tested through the matching fire detector controller, and the actual application environment of the smoke alarm system can be more accurately simulated, thereby performing more accurate quality testing on the smoke alarm system.

[0050] In an exemplary embodiment, the fire detector controller to be tested is connected to the fire detector to be tested through the fire detector installation port, and based on the received second detection instruction, the fire detector to be tested is tested, including:

[0051] The smoke generator generates smoke of a set concentration in the sealed box based on the received second detection instruction;

[0052] If the standard fire detector controller issues a smoke alarm based on the trigger signal of the fire detector to be tested, it is determined that the fire detector to be tested is qualified, and the trigger signal is the smoke generated by the fire detector to be tested based on the set concentration.

[0053] During implementation, the smoke concentration in the sealed box can be set according to relevant regulations in the train. For example, the concentration can be set according to the industry standard "Locomotive and Vehicle Fire Detector System" (GB / T38519-2022).

[0054] When the smoke concentration in the sealed box reaches the set concentration, if the fire detector is intact, it will generate a certain trigger signal and send it to the connected standard fire detector controller, and a prompt light and / or text reminder will be displayed in the standard fire detector controller. If the standard fire detector controller cannot normally perform a smoke alarm at the set concentration, it can be determined that the quality inspection of the fire detector to be tested has failed.

[0055] In this embodiment, the reason why a standard fire detector controller is used to test the fire detector to be tested is that generally speaking, fire detector controllers and fire detectors from the same batch are complete sets of equipment and are used together when in use. Therefore, they are also tested as a set during testing, which can more accurately simulate the actual working conditions.

[0056] In an exemplary embodiment, the sealed box is provided with a smoke concentration probe for sensing the smoke concentration in the sealed box.

[0057] The smoke generator and the smoke concentration probe can cooperate with each other to adjust the smoke concentration in the sealed box to a set concentration.

[0058] In an exemplary embodiment, the smoke concentration probe is an optical densitometer.

[0059] The smoke concentration probe is an optical densitometer. When there is smoke in the sealed box, the smoke will block the light of the optical densitometer, and the optical densitometer can detect the smoke concentration in the sealed box accordingly.

[0060] In an exemplary embodiment, the smoke generator is an aerosol generator.

[0061] Using aerosols to simulate real smoke is more environmentally friendly.

[0062] In an exemplary embodiment, the fire detector detection area further includes a filter box, and the sealing box and the filter box are connected through an air outlet duct.

[0063] In an exemplary embodiment, the filter box includes activated carbon.

[0064] In this embodiment, by providing a filter box and activated carbon in the filter box, aerosol smoke released from the sealed box can be effectively adsorbed to avoid pollution to the environment caused by smoke release after the detection is completed.

[0065] In actual applications, seven layers of partitions can be set in the filter box, and each layer is laid with activated carbon.

[0066] In an exemplary embodiment, a control terminal is further included, and the control terminal is used to issue a first detection instruction and / or a second detection instruction based on an external trigger;

[0067] The first detection instruction is used to detect the fire detector controller to be tested;

[0068] The second detection instruction is used to detect the fire detector to be detected.

[0069] Figure 2 This is the second structural schematic diagram of the smoke alarm system detection station provided in the embodiment of the present invention.

[0070] like Figure 2 As shown, the detection station provided in this embodiment can be powered by a 220V power supply, and can detect fire detectors through a DSP digital circuit board. The 220V power supply can be converted into a 48V power supply and a 110V power supply, which are used to power a 48V fire detector controller and a 110V fire detector controller respectively, so as to detect the fire detector controller.

[0074] Step 301, in response to the first detection instruction, adjusting the resistance value of the simulated load connected to the fire detector controller to be tested and the standard fire detector controller, if the content display of the fire detector controller to be tested is consistent with the preset detection standard, determining that the fire detector controller to be tested is qualified;

[0075] Step 302, in response to the second detection instruction, the smoke concentration in the sealed box is adjusted by the smoke generator, and the fire detector to be tested is tested by the standard fire detector controller.
