Automatic meteorological station fault handling system

Abstract

The embodiment of the invention provides an automatic meteorological station fault handling system. The system comprises a control interface, a detected sensor, a standard sensor, a data acquisition card, a test instrument, a detected collector and a computer, wherein the control interface is used for sending a standard signal source to the detected collector, or a preset programmable power supply controls the detected sensor to generate a first signal, controls the standard sensor to generate a second signal and controls the standard signal source to generate a third signal through the control interface, the detected sensor and the standard sensor are used for outputting the first signal and the second signal to the data acquisition card, the data acquisition card and the test instrument are used for calculating a first conversion numerical value according to the first signal and calculating a second conversion numerical value according to the second signal, the detected collector is used for calculating a third conversion numerical value according to the standard signal source, and the computer is used for judging whether the detected collector or the detected sensor fails. The system is used for guaranteeing maintenance of an automatic meteorological station.

Description

technical field [0001] The invention relates to the technical field of weather station detection, in particular to an automatic weather station fault processing system. Background technique [0002] An automatic weather station is a device that can automatically observe and store meteorological observation data, and is an indispensable and important data source for mesoscale and short-term weather forecasting. At present, the country has an observation network of tens of thousands of automatic weather stations. It operates 24 hours a day, collects and transmits various meteorological observation data in real time, and plays a huge social and economic benefit in disaster prevention and mitigation. [0003] At present, for the maintenance of automatic weather stations, most of the existing technologies use discrete testing instruments, such as digital multimeters, digital oscilloscopes, etc., and maintenance personnel manually test and maintain the tested components based on ...

AI Technical Summary

Problems solved by technology

[0003] At present, for the maintenance of automatic weather stations, most of the existing technologies use discrete testing instruments, such as digital multimeters, digital oscilloscopes, etc., and maintenance personnel manually test and maintain the tested components based on experience, which has a low degree of automation and lacks standardized maintenance methods.

Due to the habit of using discrete test instruments to carry out diagnosis and maintenance of automatic weather stations, resulting in a wide variety of maintenance tools, poor compatibility, and no unified technical standards, the problems of guarantee, repair and maintenance efficiency of automatic weather stations have become increasingly prominent

Specifically, the problem mainly shows that the test instruments are not unified, one type of automatic weather station equipment corresponds to multiple test instruments, the fault detection method is single, the problem is prominent, and there is no standardized test and maintenance system

Secondly, the degree of automation of detection and diagnosis is low, without intelligence, and the maintenance efficiency is extremely low. The results of testing and diagnosis vary from person to person, and resource sharing of maintenance methods cannot be realized.

Therefore, in the face of the ever-increasing demand for meteorological services, and the types of automatic weather stations are ever-changing, there is no standard fault test method, and the maintenance method is difficult to meet the requirements of high timeliness and rapid maintenance support

[0004] Therefore, a technical problem urgently needed by those skilled in the art is to propose a fault diagnosis, testing and maintenance system for automatic weather stations to solve the problems of standardization and automation of automatic weather station maintenance and maintenance, and to reduce maintenance and repair costs. Ensure long-term stable and reliable operation of automatic weather stations
