Embodiment 1
[0029] like figure 2 As shown, the specific implementation steps of fault analysis are as follows:
[0030] Step S401: Formulate equipment inspection plan, including hidden danger prediction, establishment of fault feature database and equipment history;
[0031] Step S402: according to the inspection plan, execute the inspection task of the corresponding equipment;
[0032] Step S403: judging whether there is a fault in the device;
[0033] Step S404: If there is a fault, feed back fault information, specifically including fault code, fault name and specific fault phenomenon;
[0034] Step S405: Perform equipment failure analysis according to the feedback failure information;
[0035] Step S406: According to the result of equipment failure analysis, generate equipment inspection history, including equipment basic information, inspection record information, equipment problem records, and fault level division. The breakdown level division of the air-conditioning temperature...

The invention relates to a station fault real-time monitoring system. The system comprises a data acquisition module, a historical data analysis module, a prediction and alarm module, a management anddecision module and a fault data analysis module. The data acquisition module, the historical data analysis module, the prediction and alarm module and the management and decision module are connected with the fault data analysis module. The fault data analysis module is provided with measuring points on station equipment. The monitoring data, collected by the data acquisition module, of the different measuring points is compared and analyzed according to a combination form. An analysis report including fault grading and hidden danger prediction analysis is completed according to the analysisof the historical data analysis module, and the analysis report is sent to the management and decision module. Compared with the prior art, the system has the advantages that specific fault components can be quickly determined, the fault judgment response time can be reduced, and the like.
Description
technical field [0001] The invention relates to the field of data monitoring, in particular to a station fault real-time monitoring system. Background technique [0002] Various automatic control systems (such as DCS systems, etc.) in today's high-speed rail stations are becoming more and more popular, which greatly improves the real-time and reliability of high-speed rail station facilities and equipment management. However, the DCS systems of most factories focus on core equipment such as compressors, pumps, and generators to complete the basic operation and control functions of the unit. Analysis and forecasting functions. The response of the DCS system to equipment abnormalities mostly depends on the preset upper and lower alarm limits (LL / L / H / HH) in the DCS and the corresponding chain control mechanism. While preventing major failures, it often causes emergency shutdown of equipment or units. In the high-speed rail transportation industry, even if it is a normal shut...
