Description

Technical Field

[0001] The present invention belongs to the technical field of locomotive routine operations, and more specifically, relates to an integrated sanding, sewage discharging and water replenishing operation system for locomotives and a using method thereof. Background Art

[0002] With the rapid development of railway transportation, the efficiency and quality of locomotive maintenance operations are directly related to the safety and economy of railway transportation. The "Regulations on Locomotive Maintenance Management" issued by the National Railway Group clearly states that it is necessary to improve the automation and intelligence levels of equipment and facilities, ensure the quality of locomotive maintenance while improving the maintenance efficiency, and improve the working conditions. Sanding, sewage discharging and water replenishing on locomotives are important links in locomotive maintenance, and their operation efficiency and quality directly affect the running safety and maintenance cost of locomotives. Therefore, developing an automated and intelligent operation system that integrates sanding, sewage discharging and water replenishing can not only significantly improve the efficiency and quality of maintenance operations, but also reduce the manual labor intensity, reduce human operation errors, and further ensure the safety and reliability of railway transportation.

[0003] At present, fixed sanding, sewage discharging and water replenishing equipment has been built in each large locomotive depot, initially solving the problem of scattered sanding, sewage discharging and water replenishing workstations, and effectively reducing the labor intensity of manual sanding. To a certain extent, these devices have realized mechanized operations, reduced the complexity of manual operations, and improved the operation efficiency.

[0004] Although the prior art has solved the mechanization problems of sanding, sewage discharging and water replenishing to a certain extent, there are still the following deficiencies that urgently need further upgrading and transformation: (1) Lack of real-time monitoring during the operation process: The sanding, sewage discharging and water replenishing operation process and the usage of equipment cannot be presented to the manager in real time, resulting in untimely discovery of on-site equipment problems and affecting the continuity and efficiency of maintenance operations. (2) The operation quality cannot be traced: The operation quality of sanding, sewage discharging and water replenishing lacks effective monitoring and recording, and the operation process cannot be traced. (3) Maintenance depends on manual labor: The maintenance and upkeep of the equipment mainly rely on manual spot checks and inspections, lacking an intelligent fault warning and maintenance management mechanism, resulting in a lag in discovering equipment problems and affecting normal use. (4) Unmanned operation has not been achieved: The prior art has not achieved unmanned safe sanding operation. Manual sanding operation is cumbersome and has potential safety hazards, and cannot meet the requirements of modern railway transportation for efficient and safe operations. Summary of the Invention
