Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] Such as figure 1 As shown, the present embodiment provides a method for automatic recognition of readings of substation pointer meters, which specifically includes the following steps:

[0032] Step S1: providing an image acquisition module, the image acquisition module takes an image of the pointer instrument in the substation, and transmits the collected image information to the computer through a wireless transmission module;

[0033] Step S2: The computer preprocesses the uploaded image information;

[0034] Step S3: using the improved Hough transform method to perform pointer positioning on the image processed in step S2;

[0035] Step S4: Automatically interpret the positioned image to obtain the reading of the pointer instrument in the substation;

[0036] Step S5: If the reading exceeds the range or cannot be recognized, store the imag...

Abstract

The invention relates to a method for automatic recognition of readings of pointer meters in substations. Firstly, an automatic image shooting and wireless transmission device is provided, which preprocesses the captured images, performs pointer positioning on the processed photos, and then performs positioning on the Automatic interpretation of the pointer instrument value; if the reading exceeds the range or cannot be recognized, the image will be stored separately and the reading will be performed manually. The invention can effectively solve the problems of low efficiency and inaccuracy of manual reading by automatically interpreting the pointer instrument of the substation.

Description

technical field [0001] The invention relates to the technical field of reading pointer meters in substations, in particular to an automatic identification method for readings of pointer meters in substations. Background technique [0002] 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. I...
