Description

Technical Field

[0001] The present invention relates to the technical field of ATP on-vehicle equipment detection, and particularly to a comprehensive detection platform for the engineering application of ATP on-vehicle equipment. Background Art

[0002] With the rapid development of China's high-speed rail technology, the "eight vertical and eight horizontal" high-speed rail network has been encrypted and formed. As the core equipment for controlling the operation of trains, ATP (Automatic Train Protection) on-vehicle equipment provides guarantee for the safe and stable operation of high-speed trains. After continuous technological iterations, the failure rate of this equipment has gradually decreased, and the equipment has good stability. However, after a failure occurs, there are often problems such as inaccurate positioning and long positioning time. On the one hand, due to the variety of signals of ATP on-vehicle equipment and relatively complex detection steps, on the other hand, the large number of ATP on-vehicle equipment in on-site operation poses high requirements for the professional capabilities and knowledge and skill levels of technical personnel and signal and communication personnel, thus bringing challenges to the rapid and accurate detection and verification of the main functions of the entire ATP on-vehicle equipment. Therefore, there is an urgent need to study a comprehensive detection technology for the engineering application of ATP on-vehicle equipment.

[0003] Currently, in the above-mentioned detection and verification process of ATP on-vehicle equipment, on the one hand, due to problems such as scattered test equipment, large quantity, large mass, many test items, and relatively cumbersome operation steps, the working time of technical personnel is long and test operations are prone to errors; on the other hand, due to on-site conditions restrictions, there are no conditions for detecting and verifying its main functions. For example: (1) In the article "Discussion on the Test System Scheme of CTCS3-300T On-vehicle ATP Equipment" published by Gao in Railway Signalling & Communication Engineering Technology in 2020: on the one hand, the test system is built with multiple devices, there are problems of scattered hardware and many test items, and different interfaces need to be manually connected and configuration parameters need to be set, with complex operation steps, and technical personnel are prone to make mistakes in testing due to missed steps or accidental touches; on the other hand, the system relies on dedicated simulation equipment in the laboratory environment, resulting in limited function verification. (2) In the Chinese invention patent "A Device for Detecting On-vehicle Train Automatic Protection ATP Module" with the authorization announcement number CN202204691U: on the one hand, it simplifies the installation of the ATP module, but if a complete ATP function test needs to be completed, external equipment support may still be required, and the collaborative work of multiple devices may lead to scattered test processes, increasing time and error risks; on the other hand, it mainly detects module-level equipment and cannot meet full-function coverage.

[0004] To achieve a fast, accurate, portable, and intelligent detection and verification technology, improve on-site detection efficiency and accuracy, reduce the work intensity and skill requirements of technical personnel, reduce working time, and reduce detection and verification costs, there is an urgent need for a comprehensive detection solution for the engineering application of ATP on-vehicle equipment.
