Embodiment Construction

[0023] In related technologies, radar failure prediction is implemented based on mathematical methods, such as fuzzy theory. Its essence is to rely on experts to determine reference values ​​through experience, and to perform fuzzy processing based on the reference values, which is heavily dependent on the technical level of experts and the size of the expert knowledge base. The randomness is relatively large. At present, there is no more scientific and intelligent prediction method; and Existing radar fault diagnosis systems can only diagnose faults after they occur, and cannot predict potential faults in advance in real time during radar operation.

[0024] In view of the problems existing in the related technologies, the embodiment of the present application can use the information sent by the radar equipment before the radar equipment completely fails, that is, during the incubation period of the failure, such as massive alarm data, status data and maintenance data, etc., c...

Abstract

The embodiment of the invention discloses a radar fault prediction method and device and a storage medium, and the method comprises the steps: selecting key feature data from the historical data of radar equipment based on a random forest algorithm; based on the key feature data, training to obtain a radar fault prediction model; and performing radar fault prediction based on the radar fault prediction model. According to the technical scheme, the key feature data are extracted based on the random forest algorithm, radar fault prediction is carried out through the radar fault prediction modeltrained based on the key feature data, possible potential faults of radar equipment can be predicted in advance, and the risk of service failure to be achieved by the radar equipment is greatly reduced.

Description

technical field [0001] The embodiment of the present application relates to electronic communication technology, and relates to, but not limited to, a radar fault prediction method, device and storage medium. Background technique [0002] Doppler weather radar is an active remote sensing detection tool, which plays an important role in measuring clouds, rainfall and various strong convective weather. Its working principle is based on the Doppler effect, which can measure the relative Based on the speed of the radar, under certain conditions, the atmospheric wind field, the distribution of the vertical velocity of the airflow and the turbulence situation can be inverted, which is an important tool for disastrous weather monitoring and early warning and forecasting. At present, there are nearly 200 such radar devices in the country. Based on the technical indicators, degree of automation, complexity, reliability, and maintainability of weather radars, a small fault is enough t...
