Description

Technical Field

[0001] The utility model relates to the technical field of safety early warning for a maintenance warehouse, and in particular to an intelligent early warning device for safety protection of a maintenance warehouse. Background Art

[0002] A level crossing is the intersection of a railway line and a road or other traffic line on a plane. At a level crossing, railway trains and road vehicles or pedestrians need to cross each other on the same plane, so corresponding signals and signs need to be set up to ensure traffic safety.

[0003] There are many people passing by the level crossing at the west end of the locomotive and vehicle maintenance depot. When locomotives enter and leave the depot, collisions are prone to occur due to lack of avoidance. In order to prevent personal injury incidents, an intelligent early warning device for safety protection of the maintenance depot is proposed. Alarm protection signal lights are installed at the east side of the maintenance depot, the vehicle maintenance depot, and the locomotive maintenance depot to ensure that passers-by can wait in the specified area when locomotives enter and leave the depot. It is very necessary to effectively control safety hazards. Summary of the invention

[0004] The utility model provides an intelligent early warning device for safety protection of a maintenance warehouse, which solves the technical problems in the background technology.

[0005] In order to solve the above technical problems, the utility model provides a maintenance warehouse safety protection intelligent early warning device, including a controller host module, an alarm light module, a voice alarm module and a detection sensor module;

[0006] The alarm light module is used to receive instructions from the controller host module and can emit an alarm light effect for early warning;

[0007] The voice alarm module is used to receive instructions from the controller host module and can broadcast voice for warning;

[0008] The detection sensor module includes a bidirectional monitoring sensor for detecting the position of a locomotive and a pedestrian crossing sensor for detecting the position of a passing person.

[0009] Preferably, the warning light module, voice alarm module and detection sensor module are all electrically connected to the controller host module.

[0010] Preferably, the bidirectional monitoring sensor includes a first sensor and a second sensor, and the first sensor and the second sensor are fixedly installed at the warehouse entrance and the warehouse exit, respectively.

[0011] Preferably, the detection direction of the pedestrian crossing sensor is parallel to the direction of the train.

[0012] Compared with the related art, the intelligent early warning device for safety protection of the maintenance warehouse provided by the utility model has the following beneficial effects:

[0013] The utility model provides an intelligent early warning device for safety protection of a maintenance depot. It monitors the positions of locomotives and pedestrians through detection sensor modules, promptly reminds pedestrians in dangerous areas, and reduces collisions between personnel and locomotives. The device has strong competitiveness in the railway system. Since its introduction, it has played an important protective role in the safety of level crossings in maintenance depots.

[0018] Embodiment 1, by Figure 1-3 It is given that the utility model comprises a controller host module 1, an alarm light module 2, a voice alarm module 3 and a detection sensor module 4;

[0019] The alarm light module 2 is used to receive instructions from the controller host module 1 and emit an alarm light effect for early warning;

[0020] The voice alarm module 3 is used to receive the command sent by the controller host module 1 and can broadcast the voice for warning;

[0021] The detection sensor module 4 includes a bidirectional monitoring sensor for detecting the position of the locomotive and a pedestrian crossing sensor for detecting the position of the passing personnel. The alarm light module 2, the voice alarm module 3 and the detection sensor module 4 are all electrically connected to the controller host module 1. The bidirectional monitoring sensor includes a first sensor and a second sensor, which are fixedly installed at the entrance and exit of the warehouse respectively. The detection direction of the pedestrian crossing sensor is parallel to the train direction.

[0022] In this embodiment, the bidirectional monitoring sensor can choose to use the AB phase bidirectional Hall switch of Xikong Electric. When the locomotive passes through the first sensor at the entrance, the first sensor detects the locomotive entering the warehouse and sends a signal to the controller host module 1. The PLC in the controller host module 1 follows the program (such as Figure 2As shown in the figure, the alarm signal is output, and the alarm light module 2 on both sides of the maintenance warehouse level crossing lights up. The pedestrian crossing sensor can choose to use an infrared human body sensing probe and set it above the waiting line. When someone approaches the waiting line, the pedestrian crossing sensor detects the person approaching and transmits the signal to the controller host module 1. The controller host module 1 controls the voice alarm module 3 to broadcast a reminder voice, "There is a locomotive entering or leaving the warehouse, no passage, please wait outside the line". When the pedestrian crossing sensor detects that the person has returned to the waiting line, the reminder voice stops playing. When the locomotive passes the second sensor, the system automatically stops the alarm and voice reminder, and the pedestrian can pass the level crossing normally.

[0023] Implementation steps: 1). When a locomotive enters or leaves the warehouse, the two-way monitoring sensor detects the locomotive, and the alarm light module 2 turns on the light warning. When a passing person approaches the waiting line, the voice alarm module 3 prompts "There is a locomotive entering or leaving the warehouse, no passage is allowed, please wait outside the line". When the passing person returns to the waiting line, the device only turns on the light warning.

[0024] 2). When the locomotive passes through the level crossing, after the two-way monitoring sensor is triggered, the alarm light module 2 stops the alarm and passers-by can pass normally.

[0025] 3). When the locomotive is about to enter the garage, the first sensor at the entrance is triggered and the corresponding track preparation garage door is automatically opened, and the alarm light module 2 turns on the light warning.
