Description

Monitoring analysis control method, device and system for radar

Technical Field

The present invention relates to the field of radar monitoring, analysis and control technologies, and in particular, to a radar monitoring, analysis and control method, a radar monitoring, analysis and control device, and a radar monitoring, analysis and control system.

Background

At present, various types of radars also have the problems that the on-line monitoring function is imperfect, the key operation parameters of the radars, the data transmission condition of a station, the operation conditions of the radars and accessory equipment cannot be monitored and displayed on line in real time, the key parameters of the radars and the overall performance change condition cannot be grasped dynamically, the on-line analysis of performance is lacking, and the like, so that the operation stability and the data quality of the radars are influenced to a great extent.

Because the on-line monitoring function of the radar is imperfect, various key parameters can be checked only by using an off-board instrument test mode on site, and the calibration and maintenance processes of the radar and the parameters of key devices cannot be recorded in real time, so that the change of the running state and the overall performance of each radar cannot be mastered dynamically in real time, long-term sickness work of the radar is caused, and the reasons for unstable radar performance and reduced quality of product jigsaw are difficult to trace. In addition, the on-line monitoring software of the radars of various types is self-developed by various manufacturers, the functions and the performances are different, the technical standards of data acquisition, processing, display and the like are inconsistent, so that the use and maintenance are difficult, and the transmission abnormality can not be found in time due to the lack of effective on-line monitoring of the data transmission conditions of the base data of the station, the products and the like, so that the application of the weather radar networking is greatly influenced.

At present, most radar stations lack on-line monitoring capability for environmental parameters such as temperature and humidity of a machine room and a radome, water leakage condition, video pictures and the like, and more than 30% of radar faults are caused by exceeding of the environmental parameters. In addition, the working states of auxiliary equipment such as an air conditioner, a UPS (uninterrupted power supply) and fire protection of the radar station, which influence the safe operation of the radar, cannot be automatically monitored and alarmed, whether the radar works or not and whether the working is normal or not basically depend on the frequency of a crew to patrol a machine room, and particularly, part of radar stations adopt a station-separated operation mode, and the stable and safe operation of the radar is influenced due to imperfect radar operation environment and auxiliary equipment monitoring.

Moreover, the lack of key algorithms, the lack of ability to evaluate radar calibration and operational stability online. Meanwhile, the key algorithm for evaluating the radar running state must be issued uniformly by a meteorological department, so that the situations of algorithm black box, unscientific algorithm, objectivity and non-uniform alarm threshold standard caused by independent development of manufacturers are avoided.

In addition, when the observation mode of the radar needs to be changed, safety problems occur, the radar false alarm, the computer crashes, the auxiliary equipment is powered off and restarted, and the like, the radar and the auxiliary equipment cannot be controlled, the radar is restarted in time or hidden danger affecting the safe operation of the radar is eliminated, a plurality of stations adopt the operation mode of station separation, and the stations are far apart, and particularly in hard stations, the traffic is inconvenient and the control is unchanged.
