An automatic recognition system for pointer instrument readings in substations

Abstract

The invention relates to an automatic identification system for readings of pointer meters in substations, which includes an image acquisition module for collecting image information of pointer meters in substations. The image acquisition module is connected to a computer through a wireless transmission module; processing module, pointer positioning module, reading automatic calculation module, threshold judgment module and result output module; the image filtering module and binarization processing module perform filtering and binarization processing on the image information, and transmit the processed information to The pointer positioning module, the pointer positioning module adopts the improved Hough transform method to perform pointer positioning on the image, and the reading automatic calculation module automatically interprets the positioned image to obtain the reading of the pointer instrument in the substation, and the reading is passed through the threshold judgment module , The output of the result output module. The invention can effectively solve the problem of low efficiency of manual reading, solve the problems of reading error caused by factors such as fatigue and the like.

Description

technical field The invention relates to the technical field of reading pointer meters in substations, in particular to an automatic recognition system for readings of pointer meters in substations. Background technique Pointer meters are simple in structure, cheap in price, easy to maintain, high in reliability, strong in corrosion resistance and anti-electromagnetic field interference. Based on the above advantages, most circuit breakers in substations use pointer meters to monitor their pressure values. At present, when the operation and maintenance personnel conduct maintenance inspections, most of them rely on manual interpretation to read the pressure value of the circuit breaker, record it on paper, and then manually input the recorded data into the computer after the inspection. This traditional method is not only inefficient, but also easily affected by human subjective factors, resulting in inaccurate indication results of the circuit breaker. In recent years, wit...
