Description

Technical Field

[0001] This invention relates to the field of railway platform early warning technology, and in particular to a railway platform monitoring and early warning device and its control method. Background Technology

[0002] Railway transportation is the main artery of the national economy, serving as a link between social production, distribution, exchange, and consumption. Railways are a vital means of transportation for improving people's material and cultural living standards, meeting their travel needs, and strengthening national defense. Railway transportation is closely intertwined with people's daily production activities, making the smooth and safe operation of railway transport crucial. With the continuous and rapid development of my country's railways and the increasing number of daily train departures, safety in railway operations has become increasingly important. However, safety issues at railway platform ends have consistently been a challenging problem for industry personnel.

[0003] When trains arrive and depart from the platform, safety control at the platform end relies on on-site protection and monitoring by passenger personnel. However, the platform end also requires frequent entry and exit by station staff and vehicle operations. The traditional person-to-person control model is difficult to manage effectively, and it is easy to cause dangerous situations such as abnormal intrusion into the platform boundary and crossing into the station area tracks. At the same time, congestion may occur when there are many people. In case of emergency, on-site staff cannot arrive in time, resulting in frequent casualties. There is no effective solution. In order to ensure the rescue of people from intrusion, this invention designs a railway platform monitoring and early warning device and its control method to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a railway platform monitoring and early warning device and its control method to solve the problems mentioned in the background art. The monitoring and early warning device can better monitor moving targets on the platform and make accurate judgments based on different areas of the moving targets, so as to achieve the technical purpose of all-round detection of the monitoring and early warning line. At the same time, it can prevent the moving targets from acting according to the early warning level to prevent unexpected situations.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] Preferably, a railway platform monitoring and early warning device includes an early warning processor, which is located on a central control console. The central control console controls and connects to an early warning detection device. The early warning detection device includes an early warning feedback module, an early warning identification module, an alarm module, a rejection mechanism, and an early warning execution mechanism. The early warning feedback module is connected to the central control console, the early warning identification module is connected to the early warning feedback module, the early warning identification module is connected to the alarm module, the rejection mechanism is connected to the alarm module, and the early warning execution mechanism is connected to the early warning identification module. The early warning execution mechanism includes a monitoring platform, on which a mobile detection mechanism is installed. The mobile detection mechanism includes a detection camera, which is mounted on a fixed slider. The fixed slider is mounted on a slide rail, which is mounted on an early warning frame on one side of the monitoring platform. A rejection mechanism is provided at the upper end of the mobile detection mechanism, and a linkage trigger switch is provided on the rejection mechanism.

[0007] Preferably, the early warning identification module includes a first identification module, a movement identification module, and a second identification module. The first identification module is installed at one end of the early warning frame, and the second identification module is installed at the other end of the early warning frame. The first and second identification modules monitor whether there are parked vehicles at the station, and the movement identification module monitors whether moving targets at the station enter or leave the early warning line, and respectively sends corresponding instructions to the early warning feedback module.

[0008] Preferably, the first identification module and the second identification module are respectively connected to the camera and the identification trigger. The identification trigger includes an identification sensor and an identification head. The identification sensor is installed on the monitoring platform, the identification head is installed on the identification line, and the camera moves on the fixed slider for monitoring.

[0009] Preferably, the detection camera is equipped with a centrifugal cleaning mechanism, which includes a centrifugal base and a centrifugal spring. One side of the centrifugal spring is fixedly connected to a hanging groove on the centrifugal base, and the other side of the centrifugal spring is connected to a centrifugal clamp plate. The centrifugal clamp plate is equipped with a scraper, and a trigger head is provided on one of the upper ends of the centrifugal clamp plate. The trigger head is connected to a video detection and transmission module, which is connected to the early warning feedback module. The detection camera is mounted on the upper side of the slide rail.

[0010] Preferably, the early warning frame is installed on the top of the platform near the railway track. The early warning frame includes an early warning base and an early warning support rod. The early warning base is connected to the platform, and the early warning support rod is connected to the slide rail. The early warning support rod is set at a 45-degree angle to the platform. A slide rail motor is connected to the slide rail, and the slide rail motor is rotatably connected to the slider. The upper end of the early warning support rod is connected to a monitoring station.

[0011] Preferably, the rejection mechanism includes a rejection base and a rejection frame. The rejection base is installed on the lower side of the slide rail, the rejection frame is installed on the rejection base, and an elastic airbag is installed on the rejection frame. The upper and lower ends of the elastic airbag are provided with binding elastic nets.

[0012] Preferably, the elastic binding net is disposed outside the pop-up cylinder, the pop-up distance of the elastic binding net is 3-4m, and the retraction distance of the elastic binding net is 0.5-1m.

[0013] Preferably, the linkage trigger switch is connected to the alarm module, the blocking frame is a mesh telescopic frame, and telescopic hooks are provided at both ends of the mesh telescopic frame. The telescopic hooks are linked with the linkage trigger switch.

[0014] Preferably, a control method for a railway platform monitoring and early warning device includes the following steps:

[0015] S1: The first and second identification modules can identify whether a vehicle has entered the platform. When a vehicle stops at the platform, the moving identification block connects to the detection camera of the mobile detection mechanism to detect and issue a warning to the personnel that appear. When a moving target enters or leaves the warning line, it sends a corresponding instruction to the warning feedback module.

[0016] S2: When personnel linger at the cordon, the camera simultaneously locates their position and collects the location information through the early warning recognition module. The early warning recognition module then feeds the information back to the early warning feedback module. The early warning feedback module processes the information and sends it to the central control console processor for processing. The personnel are then notified or broadcast the information to drive them away.

[0017] S3: During the inspection of the camera's back-and-forth patrol of the platform, each patrol lasts 10-30 seconds. During the patrol, longitudinal centrifugal force is generated. After the centrifugal spring torque of the centrifugal cleaning mechanism is less than the centrifugal force, the centrifugal plate cleans the dust from the camera lens. At the same time, the centrifugal plate triggers the contact head once each time it is cleaned, and the camera transmits video information once. Meanwhile, when not patrolling, the video detection and transmission module does not transmit video to ensure good signal of the information transmission network.

[0018] S4: During this process, if a target appears within the warning line, the detection camera will detect and transmit the information. During transmission, the motion recognition module will transmit the information to the early warning feedback module, which will then transmit the information to the early warning processor. The early warning processor will analyze the information and issue an early warning, triggering the alarm module and displaying the alarm. Simultaneously, the detection camera will locate the target within the warning line and process its position information. The processor will then send a denial execution command. During this process, the denial mechanism will trigger the denial frame to fall, and the elastic airbag will deploy. As the elastic airbag deploys, the binding net will deploy, binding and retracting the target beyond the warning line by 0.5-1m to ensure the target's safety.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The early warning processor can process and store the feedback information from various modules. The feedback module, identification module, and alarm module of the early warning detection device can identify the information according to different situations and feed it back to the processor. The processor processes the information according to the various parameters set by the processor, thereby improving the information processing and identification capabilities. In case of emergency, the feedback alarm module will handle the emergency alarm, improve the timeliness of information feedback, reduce the shortcomings of insufficient personnel response and emergency response, and improve the response time for handling and dealing with emergencies.

[0021] 2. The first and second identification modules can identify whether there are vehicles in the station and feed the information back to the processor to determine whether to operate the actuator.

[0022] 3. Identification is performed by cameras through the first and second identification modules, and the entry and exit of vehicles are detected by identification sensors. The identification head is installed on the identification line, and the identification line is set on the warning line.

[0023] 4. The centrifugal cleaning mechanism cleans the camera's mirror surface to ensure image cleanliness. During the cleaning process, it connects with the trigger head to transmit control information, ensuring that the data is transmitted once for each movement during operation. The centrifugal cleaning mechanism can be temporarily stopped when no vehicles are entering the station, thus reducing the impact on camera operation.

[0024] 5. The warning support rods installed on the warning frame can support the slide rail motor and slider, and at the same time, the rejection mechanism can be installed more stably, ensuring the stability of the rejection frame during operation.

[0025] 6. The design of the rejection base and rejection frame ensures the safety of personnel in emergencies and during the withdrawal of the net. It also improves the response time for emergency rescue and prevents the problem of staff being unable to provide rescue due to distance, thus greatly improving the emergency response capability.
