Digital display instrument identification method suitable for substation inspection robot

Abstract

The invention discloses a digital display instrument identification method suitable for a substation inspection robot. The method comprises the steps that a digital area is located; all target areas of a digital display instrument are screened; the minimum circumscribed rectangle of the target areas is extracted; rectangular areas are screened; the remaining rectangular areas are all taken out asdigital areas to be identified; and finally, character identification is carried out after preprocessing. According to the invention, an image collected by the indoor small inspection robot can be quickly processed; the indications of various digital instruments are converted into numbers, and the numbers are transmitted to a background server in real time through the network function of the inspection robot; and digital display instrumentation in a control room of a substation can be remotely monitored.

Description

technical field [0001] The invention belongs to the field of inspection of substation equipment, and in particular relates to a digital display instrument recognition method suitable for a substation inspection robot, which can be used for data collection of indoor digital display instruments by the substation inspection robot. Background technique [0002] At present, the equipment inspection work of substations in my country generally adopts the method of manual inspection and manual recording. With the expansion of substation scale, the inspection area continues to increase, and the operating environment becomes more complex, which makes the inspection scope and workload of substation on-site equipment change. Large, simply relying on the senses and experience of inspectors, it is difficult to achieve comprehensive and accurate inspections, resulting in hidden dangers in the safe operation of equipment and power grids. [0003] With the development and maturity of robot te...

Problems solved by technology

For example, the substation intelligent inspection robot of Shandong Luneng Group, the infrared thermal imager intelligent robot of Shanghai Pumeng Optoelectronics, and the substation inspection robot of Hangzhou Shenhao, etc., but without exception, these robots are large in size, heavy and costly Expensive, and can only recognize the shortcomings of pointer instruments, not suitable for environments equipped with digital display instruments such as substation control rooms
