Method for failure prediction of infrared hot box audio channel

Abstract

The invention discloses a method for failure prediction of an infrared hot box audio channel.With an infrared hot box channel monitoring and diagnostic system as the basis, a failure prediction module is arranged on a monitoring diagnosis platform to predict a system state and judge whether failures occur in a period of time.The failure prediction module comprises a data processing module, a model building module, a state prediction module and a failure judgment module.The data processing module receives and analyzes data uploaded by a diagnostic device, and analyzes the data according to a protocol and stores the data into a database.The model building module extracts data from the database and uses a grey system theory to build a model.The state prediction module predicts signal characteristics according to a system model.The failure judgment module sets a signal characteristic threshold.According to the method, the system model is built through the grey system theory, the system state is predicted, the failure trend is found timely, preventive measures are taken, the operation and maintenance efficiency is improved, and the traffic safety is guaranteed.

Description

technical field [0001] The invention relates to the field of fault prediction of an infrared shaft temperature detection system, in particular to a fault prediction method for an audio channel of an infrared thermal shaft. Background technique [0002] The infrared axle temperature detection system is widely used in railway systems, and uses the principle of infrared temperature measurement to monitor the axle temperature of running vehicles in real time. The system effectively prevents the vehicle from cutting the axle, achieves good results and plays an important role in ensuring driving safety. [0003] The infrared thermal shaft channel monitoring and diagnosis system monitors the working status of the infrared shaft temperature detection system in real time. When the status is abnormal, it can promptly determine whether the fault occurs in the infrared host or the communication line, which clarifies the responsibilities of the vehicle department and the communication de...
