Description

Technical Field

[0001] The present invention relates to the technical field of transportation equipment control, and particularly to a method and device for positioning correction and theft determination of an intelligent wheel stopper. Background Art

[0002] In the fields of railway and road transportation, the wheel stopper is a key device to ensure the safety of vehicle parking, and the reliability and stability of its performance are crucial. Traditional wheel stoppers have relatively single functions and can only block the rolling of wheels through physical structures, and there are many deficiencies in positioning accuracy and anti-theft protection.

[0003] On the one hand, in scenarios such as railway freight yards and parking lots, since the vehicle parking positions need to be accurately planned, if the placement position of the wheel stopper is deviated, it not only cannot effectively prevent the vehicle from sliding, but may also affect the subsequent operation process and pose a safety hazard. In the past, workers needed to manually check the position of the wheel stopper regularly, which not only consumed a large amount of manpower, but also was difficult to monitor in real time and correct quickly;

[0004] On the other hand, wheel stoppers are mostly deployed outdoors and are easily targeted for theft. Once stolen, it will not only cause equipment losses, but may also trigger serious safety accidents due to accidental sliding of the vehicle. Existing anti-theft measures lack intelligent monitoring means and rely on simple locks, and cannot perceive the displacement and damage of the wheel stopper in real time, making it difficult to issue alarms and take effective countermeasures in a timely manner.

In addition to the deviation value exceeding the threshold, triggering the correction instruction also requires judging whether the deviation duration exceeds the second threshold, and excluding the influence of natural displacements in combination with environmental sensor data. This avoids false corrections caused by momentary interference or natural factors, improves the accuracy of triggering the correction instruction, and makes the correction operation more targeted and reasonable.

[0096] The working principle of the above embodiments is as follows: Positioning and deviation correction working process: Multiple sensors, such as GPS / Beidou positioning modules, inertial measurement units (IMUs), ultrasonic ranging sensors, and vision positioning modules, are always in working state to collect the position data of the wheel stopper in real time. These different types of sensors cooperate with each other. Even in complex environments such as signal occlusion and insufficient light, they can ensure the accuracy and reliability of data collection. The collected position data is transmitted to the data processing module, which compares it with the preset reference position and calculates the position deviation value. At the same time, the module also records the duration of the deviation and combines the data collected by the environmental sensors to determine whether there is displacement caused by natural factors such as wind force and slope. When the deviation value exceeds the first threshold, the deviation duration exceeds the second threshold, and the influence of natural displacement is excluded, the data processing module triggers a deviation correction instruction. The instruction is transmitted to the actuator through the wireless communication module. The actuator uses an electric push rod or a hydraulic adjustment device to adjust the wheel stopper to the reference position and complete the deviation correction operation;

[0097] Theft determination working process: The system continuously monitors the displacement of the wheel stopper. Once an unauthorized displacement event is detected, it immediately evaluates the displacement speed. When the displacement speed exceeds the preset safety speed, the system automatically activates the vibration sensor array to start collecting multi-dimensional vibration data. The vibration data collected by the vibration sensor array is transmitted to the pattern recognition processor. The processor compares the received vibration spectrum characteristics with the pre-stored typical damage vibration characteristic library to determine whether the current vibration belongs to the human damage mode. At the same time, the pressure sensor continuously detects the wheel-rail contact state. If wheel-rail separation and continuous displacement are detected, the system will increase the confidence level of theft determination. If the vibration spectrum characteristics match the human damage characteristics and the displacement continues, the system will trigger an anti-theft alarm. Specific measures include sending an alarm signal containing the position information of the wheel stopper to the management platform, activating the local sound and light alarm device, and automatically locking the braking mechanism of the wheel stopper at the same time to prevent the theft behavior from further developing;

[0098] The overall working process of the intelligent wheel stopper system: The solar power supply system provides power support for each module such as the positioning and deviation correction device, the theft determination device, and the central control unit. The central control unit is responsible for coordinating the collaborative operation of the positioning and deviation correction device and the theft determination device to ensure the orderly operation of the entire system. The blockchain evidence storage module encrypts and stores the displacement event data of the wheel stopper to ensure the security and traceability of the data. The self-check module regularly checks the working status of each sensor to detect and solve potential equipment failures in time, and ensures the stable operation of the entire intelligent wheel stopper system.
