Abstract

The invention relates to the technical field of equipment monitoring, in particular to an online inspection monitoring system for high-voltage equipment. According to the invention, a temperature sensor and an infrared timing correction module are arranged, the infrared camera is corrected in a timing mode, the detection precision of the infrared camera is guaranteed, and therefore the collection precision of the infrared video monitoring system is improved, and the monitoring precision of the system is improved. According to the system, a entropy function is adopted as a focusing evaluation function, the system is simple and easy to implement, the rapidity of a step-by-step search method and the high-precision characteristic of a split method are integrated, local optimization is achieved, the high sensitivity of the entropy function is matched, and the automatic focusing speed and precision are improved. According to the system, the background image and the movable video part of the monitoring system are separated in advance, the background image is identified in advance, and only the movable video part is transmitted during transmission, so that the number of video data needing to be transmitted is greatly reduced, the possibility of channel blockage is reduced, and the reliability and the safety of monitoring video transmission are improved.

Description

technical field [0001] The invention relates to the technical field of equipment monitoring, in particular to an online inspection and monitoring system for high-voltage equipment. Background technique [0002] High-definition visible light detection is commonly used in the fault detection of EHV / UHV substations and transmission lines, and visible light detection is relatively mature. Infrared temperature measurement technology has the advantages of non-contact, fast, and accurate. Infrared thermal imaging cameras can not only accurately measure the temperature of objects, but also obtain thermal images corresponding to the thermal distribution field on the surface of the measured object. Infrared thermal imaging technology has important applications in the fields of military, security, product quality control and monitoring, equipment online fault diagnosis and safety protection, and its development and application prospects are broad. Ultraviolet power detection technolog...
