Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment management, and in particular to a method and system for calculating the working hours of mechanical equipment. Background Art

[0002] The working time calculation of mechanical equipment mainly involves the estimation and recording of the time required for the processing of mechanical equipment to ensure production efficiency and cost control; this process includes multiple aspects, from the calculation of working time quotas to the time allocation of specific processing procedures, all in order to optimize the production process and improve work efficiency; the working time calculation of mechanical equipment mainly includes working time quota calculation, machining working time calculation, working time quota manual, machining working time calculation and mechanical maintenance standards.

[0003] Existing methods for calculating working hours of mechanical equipment are usually based on sensors and cloud servers. By installing sensors in mechanical equipment and uploading the collected data through cloud servers for collection and management, it is possible to effectively calculate working hours for different mechanical equipment, so as to improve the efficiency of working hour calculation and the applicability of data analysis. This improved method can improve the applicability of management when managing different mechanical equipment, but it is impossible to judge the operating status of the mechanical equipment by only collecting data on the operating time of the mechanical equipment, resulting in errors in working hour calculation when the mechanical equipment is in a stopped and idling state for a long time, thereby failing to timely troubleshoot the mechanical equipment or directly affecting the actual production efficiency. For example, in a patent application with publication number CN113984185A, a system and method for calculating the working hours of mechanical equipment are disclosed. The solution is to monitor the mechanical equipment by installing sensors and perform data analysis through a cloud server to achieve strong applicability and can be used for calculating the working hours of different mechanical equipment. Other improvements in the working hour calculation for mechanical equipment are usually improvements in the investigation of working hour data, but it is still impossible to judge the operating status of the mechanical equipment, resulting in errors in the working hour calculation when the mechanical equipment is in a stopped and idling state for a long time, thereby failing to timely investigate the faults of the mechanical equipment or directly affecting the actual production efficiency.

A method for calculating working hours of mechanical equipment according to claim 8, characterized in that: Based on the total shaft speed characteristics of the working time equipment, the operation status of the working time equipment is monitored in real time, and based on the monitoring results, the working time of the working time equipment is obtained and the working time equipment is processed, which also includes: When the same collection bearing CZ in the working time equipment is recorded as idling state twice in succession, the working time equipment is turned off and the working time of the working time equipment at this time is recorded as the working time of the working time equipment.

10. A working time calculation system for mechanical equipment, used to implement a working time calculation method for mechanical equipment according to any one of claims 1 to 9, characterized in that: It includes data extraction module, variance interval acquisition module and working time judgment processing module; The data extraction module records the mechanical equipment used to calculate the working hours as working time equipment. For any working time equipment, the historical working data of the working time equipment is obtained based on terminal collection; The variance interval acquisition module is used to analyze the historical working data of the working time equipment using the shaft speed analysis method, and obtain the static variance interval, idle variance interval and working variance interval corresponding to the working time equipment based on the analysis results; The working time judgment processing module is used to record the static variance interval, the idle variance interval and the working variance interval as the total shaft speed characteristics of the working time equipment; during the working time of the working time equipment, the operating status of the working time equipment is monitored in real time based on the total shaft speed characteristics of the working time equipment, and the working time of the working time equipment is obtained based on the monitoring results and the working time equipment is processed.
