At present, the maintenance management system of accident maintenance and planned maintenance which is still implemented from fifty years is still implemented in China. Although work such as "standardized inspection" has been carried out in recent years, these only enhance the quality control of the inspection process. The accident maintenance is a recovery maintenance after the power generation equipment has an accident, and the aim of recovering the safe operation of the equipment is realized by adopting means of repair, partial replacement or complete replacement; the periodic maintenance is a preventive maintenance which initially performs periodic maintenance of the equipment according to a maintenance cycle recommended by the manufacturer, which cycle, once determined, does not change. The overhaul project is generally a standard project determined according to relevant standards, a special project determined according to known equipment defects before shutdown, and a technical transformation project composition determined for improving the safety and economic operation level of a unit. The regular maintenance of the equipment is mainly to hope to find out potential faults of the equipment through disassembly so as to ensure that a unit can safely operate for a period of time after maintenance.

Secondly, the overall management of the overhaul lacks systematicness and scientific analysis, the periodic rationality and the necessity of regular inspection of the equipment are very worthy of state evaluation and experience evaluation, the equipment is exhausted after the fact, and the analysis of the equipment defects is not really reflected to the subjective analysis of people and the state analysis of a software system. Finally, a remote expert guidance team is not precise and non-specialized, and for many detection items, such as integrated vibration analysis, dynamic balance test, oil analysis, infrared thermal imaging, ultrasonic leak detection and the like, the specialization is high, and some overhauling parties have equipment without exquisite technology, some overhaul parties have no supervision system, and some continuous measurement technical tools do not. The operation and maintenance data analysis system only depends on manual analysis and does not perform post analysis; the equipment ledger lacks a uniform system, so that all data are considered to be manually input, and even key equipment ledgers of some departments are incomplete; the operation and maintenance are responsible for respective lack of supervision and management traces of own departments, planning departments, operation departments and the like of the equipment department. The running analysis of the equipment and the system lacks the contrast trace of the monthly, the quarterly and the annual, and is not effectively fused with the state of the equipment.

For the inspection and repair of the external package, the management means of the prior art scheme is not enough, and firstly, the supervision of personnel is realized; secondly, supervision of on-site operation and maintenance operation; and thirdly, the modules are communicated with each other, and the real-time and historical retrospective supervision of the machine account is built.
