Abstract

The invention relates to a meteorological measuring instrument, in particular to a device capable of diagnosing a failure of a visibility sensor and a detection method. Mainly for the diagnosis of the visibility sensor, the equipment includes limit switches, stepping motors, chassis, support columns, columns, cross arms, holding plates, control boxes, detection devices, motor brackets, and fixed feet. The detection device is driven to rotate by the stepping motor, so that the detection device sequentially covers the laser detection area of ​​the measured visibility sensor, and the measured visibility sensor uploads the captured meteorological visibility status data to the host computer software. The host computer software compares the visibility difference of different detection devices with the standard deviation, and judges whether the measured visibility sensor is faulty or not through the judgment of the measured data and the difference. The equipment has the advantages of high degree of automation, convenient operation and maintenance.

Description

technical field [0001] The invention relates to a meteorological measuring instrument, in particular to a device capable of diagnosing a failure of a visibility sensor and a detection method. Background technique [0002] Visibility sensor is a kind of meteorological instrument with high sensitivity and strict requirements. After the instrument usually works for a period of time, its accuracy should be tested. The conventional method is to send the visibility sensor to the national or provincial measurement unit, and use the visibility simulation test, which is a waste of time, manpower and financial resources. Usually the detection of the visibility sensor is mainly to manually block the receiving end lens of the visibility sensor and compare the performance of the sensor with the standard visibility sensor. Therefore, the conventional method does not consume much time and manpower. Contents of the invention [0003] The object of the present invention is to provide a k...
