Fault detection device for Gray code disk wind-direction sensor

Abstract

The invention discloses a fault detection device for a Gray code disk wind-direction sensor, which comprises a wind-direction interface circuit, a processor and a display unit, wherein the wind-direction interface circuit is connected with the Gray code disk wind-direction sensor and used for receiving Gray code signals acquired and outputted by the Gray code disk wind-direction sensor, the processor is connected with the wind-direction interface circuit and used for receiving the Gray code signals, judging whether each code channel has two states '0' and '1' or not and further generating fault detection results to be outputted, and the display unit is connected with the processor and used for receiving the fault detection results outputted by the processor and displaying the fault detection results. By means of matching software design with a hardware circuit, faults of the Gray code disk wind-direction sensor are rapidly detected, the inherent quality of wind-direction detecting data can be improved by timely discovering the faults of the wind-direction sensor, and then accuracy of wind-direction monitoring results is enhanced. The fault detection device is high in automation degree, a man-machine interface is friendly, and fault detection and maintenance efficiency of the wind-direction sensor are improved.

Description

technical field [0001] The invention belongs to the technical field of fault detection, and in particular relates to a fault detection device designed for a Gray code disk wind direction sensor. Background technique [0002] At present, the detection device with relatively good application effect and wide application range in wind direction detection is a photoelectric encoder disc, that is, Gray code disc. Its advantages are that the accuracy and resolution of wind direction detection are relatively high, and it has non-contact friction, Features such as long life. Because the sensors used to detect wind direction are generally installed outdoors, they have been exposed to wind, sun, and rain for a long time, and the working environment is very harsh. As a result, the wind direction sensors often break down and cannot maintain long-term stable operation. Moreover, after the failure of these wind direction sensors, the detected wind direction data is still output on the use...

Problems solved by technology

Because the sensors used to detect wind direction are generally installed outdoors, they have been exposed to wind, sun, rain and rain for a long time, and the working environment is very harsh. As a result, the wind direction sensors often break down and cannot maintain long-term stable operation.

Moreover, after the failure of these wind direction sensors, the detected wind direction data is still output on the user terminal, but some orientations are missing. Only after comparing and analyzing the data collected during this period can it be found that

Therefore, the concealment of faults is very strong, which also greatly affects the authenticity and credibility of data collection
