[0037] The technical solution of the embodiment of the utility model solves the potential safety hazard problem existing at the maintenance passage entrance of the maintenance depot by setting up a maintenance passage protection system, and can avoid unexpected safety accidents caused by illegal operations, and ensure the safety of vehicles and maintenance personnel during maintenance operations.

[0038] Optionally, Figure 3 FIG. 1 is a structural diagram of another motor vehicle maintenance channel protection system provided according to an embodiment of the utility model. Figure 3 The contact network 140 is connected to the locomotive interlocking module 110 through the isolating switch 150. When the contact network 140 is powered on, the isolating switch 150 is turned on, the locomotive interlocking module 110 outputs a first control signal, and the protective door control module 120 controls the maintenance channel protective door 130 to be closed according to the first control signal; when the contact network 140 is powered off, the isolating switch 150 is disconnected, the locomotive interlocking module 110 outputs a second control signal, and the protective door control module 120 controls the maintenance channel protective door 130 to be opened according to the second control signal.

[0039] Specifically, the isolating switch 150 is a control switch between the contact network 140 and other equipment and lines. When the contact network 140 is powered on, the isolating switch 150 is turned on, and the locomotive interlocking module 110 receives the closing signal of the isolating switch 150, and outputs a first control signal to the protective door control module 120 to control the maintenance channel protective door 130 to close, so that when the contact network 140 is powered on, maintenance personnel are prohibited from approaching the vehicle through the maintenance channel entrance to prevent accidental safety accidents.

[0041] Specifically, the sound and light alarm unit 121 can be a device for issuing sound warnings and light warnings. When the locomotive interlocking module 110 outputs a first control signal to control the maintenance passage protection door 130 to be closed or outputs a second control signal to control the maintenance passage protection door 130 to be opened, the sound and light alarm unit 121 will issue a sound warning and a light warning within a preset time to remind the staff that the maintenance passage protection door 130 is about to be opened or closed.

[0042] Optionally, based on the above embodiment, continue to refer to Figure 4 The protection door control module 120 also includes a delay control unit 122, which is connected to the locomotive interlocking module 110; the delay control unit 122 controls the maintenance channel protection door 130 to start closing after a preset time delay according to the first control signal; the delay control unit 122 controls the maintenance channel protection door 130 to start opening after a preset time delay according to the second control signal.

[0043] Specifically, the delay control unit 122 can be a driving motor for driving and controlling the opening or closing of the maintenance channel protection door 130. When the locomotive interlocking module 110 outputs the first control signal, the delay control unit 122 starts timing, and the sound and light alarm unit 121 issues a sound warning and a light warning within the preset time, and the maintenance channel protection door 130 starts to close after the preset time is reached. Similarly, when the locomotive interlocking module 110 outputs the second control signal, the delay control unit 122 starts timing, and the sound and light alarm unit 121 issues a sound warning and a light warning within the preset time, and the maintenance channel protection door 130 starts to open after the preset time is reached.

[0044] Optionally, Figure 5 This is a schematic diagram of the position structure of a maintenance passage protection door when it is opened according to an embodiment of the utility model. Figure 2 , Figure 4 and Figure 5 , the protection door control module 120 also includes a first limiting unit 123 and a second limiting unit 124, and the first limiting unit 123 and the second limiting unit 124 are respectively connected to the locomotive interlocking module 110. When the maintenance passage protection door 130 is opened to the first position, the first limiting unit 123 sends a third control signal to the locomotive interlocking module 110, and the locomotive interlocking module 110 controls the maintenance passage protection door 130 to stop opening according to the third control signal; when the maintenance passage protection door 130 is closed to the second position, the second limiting unit 124 sends a fourth control signal to the locomotive interlocking module 110, and the locomotive interlocking module 110 controls the maintenance passage protection door 130 to stop closing according to the fourth control signal. The first limiting unit 123 includes a return sensor, and the second limiting unit 124 includes an in-position sensor.

[0045] Specifically, the maintenance channel protection door 130 needs to stop opening or closing after opening or closing to a certain extent. The first position may be set at the maximum position that the maintenance channel protection door 130 can open. When the maintenance channel protection door 130 is opened to the first position, the first limit unit 123 sends a third control signal to the locomotive interlocking module 110, and the locomotive interlocking module 110 controls the maintenance channel protection door 130 to stop opening. At this time, the maintenance channel protection door 130 is open, and the staff can pass through the maintenance channel. The second position may be set at the maximum position that the maintenance channel protection door 130 can close. When the maintenance channel protection door 130 is closed to the second position, the second limit unit 124 sends a fourth control signal to the locomotive interlocking module 110, and the locomotive interlocking module 110 controls the maintenance channel protection door 130 to stop closing. At this time, the maintenance channel protection door 130 is closed, and the staff cannot pass through the maintenance channel. Exemplarily, the first limiting unit 123 may be a return sensor. When the maintenance passage protection door 130 is opened to the first position, the return sensor sends a third control signal to the locomotive interlocking module 110, and the locomotive interlocking module 110 controls the maintenance passage protection door 130 to stop opening. The second limiting unit 124 may be an in-position sensor. When the maintenance passage protection door 130 is closed to the second position, the in-position sensor sends a fourth control signal to the locomotive interlocking module 110, and the locomotive interlocking module 110 controls the maintenance passage protection door 130 to stop closing.

[0046] Optionally, based on the above embodiment, continue to refer to Figure 4 The protective door control module 120 further includes a display unit 125, which is connected to the locomotive interlocking module 110; after the maintenance passage protective door 130 stops opening, the display unit 125 sends a safe passing signal; after the maintenance passage protective door 130 stops closing, the display unit 125 sends a communication prohibition signal. The display unit includes an LED screen.

[0047] Specifically, the display unit may be an LED screen. When the inspection channel protection door 130 is opened to the first position and stops opening, the LED screen displays green light and emits the words "safe passage", prompting the staff to pass. When the inspection channel protection door 130 is closed to the second position and stops closing, the LED screen displays red light and emits the words "no passage", prompting the staff to prohibit passage.

[0048] Optionally, based on the above embodiment, continue to refer to Figure 4 The locomotive interlocking module 110 is also used to output a first control signal when a driving signal is obtained, and the protective door control module 120 controls the maintenance passage protective door 130 to close according to the first control signal.

[0049] Specifically, before the locomotive to be repaired starts, the locomotive interlocking module 110 will obtain the driving signal and output the first control signal to the protection door control module 120 to control the maintenance passage protection door 130 to close. Thus, the maintenance passage is closed before the locomotive is driven, preventing maintenance personnel from approaching the vehicle through the maintenance passage, and preventing unexpected safety accidents.

[0050] Optionally, based on the above embodiment, see Figure 2 and Figure 5 The maintenance passage protection door 130 is arranged on both sides of the maintenance passage opening 160 .

[0051] Specifically, when the locomotive interlocking module 110 sends a first control signal to close the maintenance passage protection door 130, the maintenance passage protection doors 130 on both sides of each pair of maintenance passage openings 160 are opened or closed at the same time. Thus, when maintenance is required, all passage openings remain unobstructed; when maintenance is not possible, all passage openings are prohibited from passing, so as to avoid accidental safety accidents caused by workers entering by mistake.

[0052] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be performed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.
