Abstract
Description
Technical Field
[0001] This invention relates to the field of hook lifting detection technology in marshalling yards, specifically to an intelligent hook lifting result detection method for hump yards. Background Technology
[0002] With the continuous growth of freight volume, the uncoupling and dismantling process at marshalling yards has become an important factor restricting the improvement of marshalling yard capacity. Currently, most uncoupling operations are completed manually, usually by two people, one responsible for uncoupling and the other for monitoring.
[0003] The coupling monitoring process is as follows: After the coupling personnel complete the coupling action, as the train continues to move, depending on the number of cars to be uncoupled, uncoupling will occur near the hump. The uncoupled cars will slide at an increasingly faster speed, thus separating from the uncoupled train. The coupling monitoring personnel are responsible for monitoring whether the coupling rods of the uncoupled cars have returned to their original positions and whether they can be successfully uncoupled. If they cannot be successfully uncoupled, the coupling monitoring personnel need to perform a second coupling. If they still cannot be coupled, the shunting foreman needs to be notified for further operations. Therefore, manual operation has the following drawbacks:
[0004] 1. It requires a dedicated person to inspect the lifting results, which wastes manpower.
[0005] 2. The judgment of the hook lifting result involves subjective factors.
[0006] 3. There is a lag in the feedback of test results.
[0007] 4. The inspection process is carried out simultaneously with the train's movement, which often results in the operator moving with the train, making them susceptible to mechanical injury during the process. Summary of the Invention
[0008] (a) Technical problems to be solved
[0009] To address the shortcomings of existing technologies, this invention provides an intelligent method for detecting the lifting results of hump yard hooks. By adding key equipment such as lidar and connecting to the existing system of the marshalling yard to acquire data, the robot uses AI algorithms to replace manual inspection of the lifting results and automatically provides feedback on the inspection information. This saves manpower, shortens the inspection feedback time, and reduces the probability of workers suffering mechanical injuries.
[0010] (II) Technical Solution
[0011] To achieve the above objectives, the present invention provides the following technical solution: a method for detecting the results of intelligent hook lifting of camel humps, specifically comprising the following steps:
[0012] S1. Obtain the car number to be de-stitched from the DCD-TH system, and obtain the location A of the car to be de-stitched in each work area through the lidar equipment in each work area;
[0013] S2. Obtain the expected decompilation location B by accessing the AITG system;
[0014] S3. Compare the car position A that needs to be de-wrapped obtained in step S1 with the expected de-wrapping position B obtained in step S2. If the position of the target car does not reach the expected de-wrapping position, that is, AB is not within the ±10cm range, return to step S1 to re-detect.
[0015] S4. When the target car reaches the expected uncoupling position, that is, AB is not within ±10cm, the speed X of the uncoupling car and the speed Y of the car to be uncoupling are detected respectively, and the speed values are obtained from the STP system.
[0016] S5. First, determine whether the speed X of the undecoupled car is consistent with the speed obtained from the STP system. Then, determine the magnitude of the speed X of the undecoupled car and the speed Y of the car to be decoupled, i.e., whether YX > 0. Also, determine whether the speed difference between the speed Y of the car to be decoupled and the speed X of the undecoupled car is increasing.
[0017] S6. If the speed X of the uncoupling car is consistent with the speed obtained from the STP system, and YX > 0 and YX shows an upward trend, then the uncoupling is successful; otherwise, the uncoupling fails and an alarm is displayed on the system interface.
[0018] Preferably, in step S1, the DCD-TH system is a shunting order information management system already deployed at the marshalling yard, used to obtain shunting operation notifications.
[0019] Preferably, in step S4, the STP system is a wireless shunting locomotive signaling and monitoring system already deployed at the marshalling yard, used to obtain the precise speed of the train from this system.
[0020] Preferably, in step S2, the AITG system is a hump intelligent hook lifting system, used to obtain the hook lifting completion signal and the uncoiling position signal from the system.
[0021] Preferably, the lidar device in step S1 is equipped with an AI algorithm, which is used by the robot to replace manual inspection of the hook lifting result.
[0022] Preferably, the intelligent hook lifting result detection method for the hump is controlled by an intelligent hook lifting detection system, which communicates with the DCD-TH system, STP system and AITG system respectively through a jump server, and communicates with the lidar equipment through a VPN encrypted channel.
[0023] Preferably, the intelligent hook detection system includes a control server, a user server, a database server, an industrial switch, and a 5G router.
[0024] Preferably, the network communication of the VPN encrypted channel uses RSA dual-key reversible encryption, so that data leakage will not result in reverse decryption.
[0025] (III) Beneficial Effects
[0026] This invention provides an intelligent hump car uncoupling result detection method. Compared with the prior art, it has the following advantages: The intelligent hump car uncoupling result detection method specifically includes the following steps: S1, obtaining the car number to be uncoupled from the DCD-TH system, and obtaining the position A of the car to be uncoupled in each working area through the lidar equipment of each working area; S2, obtaining the expected uncoupling position B by accessing the AITG system; S3, comparing the position A of the car to be uncoupled obtained in step S1 with the expected uncoupling position B obtained in step S2. If the position of the target car has not reached the expected uncoupling position, that is, AB is not within the ±10cm range, then return to step S1 to re-detect; S4, if the position of the target car has reached the expected uncoupling position, that is, AB is not within the ±10cm range, then detect the speed X of the uncoupled car and the speed Y of the car to be uncoupled respectively, and obtain the speed value from the STP system; S5, firstly, determine whether the speed X of the uncoupled car is compared with the speed Y obtained from the STP system. If the speeds are consistent, then determine the magnitude of the speed X of the un-decoupled car and the speed Y of the car to be decoupled, i.e., whether YX > 0, and determine whether the speed difference between the speed Y of the car to be decoupled and the speed X of the un-decoupled car is increasing. S6. If the speed X of the un-decoupled car is consistent with the speed obtained from the STP system, and YX > 0 and YX is increasing, then the uncoupling is successful; otherwise, the uncoupling fails, and an alarm is displayed on the system interface. By adding key equipment such as laser radar and connecting to the existing system of the marshalling yard to obtain data, the robot can replace manual inspection of the uncoupling results through AI algorithms and automatically provide feedback on the inspection information. This saves manpower, shortens the inspection feedback time, reduces the probability of mechanical injury to workers, and reduces the number of personnel for uncoupling inspection. Because the number of operators is reduced, the mechanical injury of personnel is greatly reduced, effectively improving the efficiency of hump uncoupling result inspection.
