Intelligent GIS pressure gauge wireless direct reading device

Abstract

The invention discloses an intelligent GIS pressure gauge wireless direct reading device which is mechanically connected with a GIS pressure gauge and mainly comprises a lighting module, an imaging module, a pointer recognition module, a picture compression module, a wireless transmission module and a low-power-consumption battery power supply management module for supplying power to the five modules. After the wireless direct reading device is awakened to work, the lighting module is started, the imaging module starts to capture a dial plate picture and transmits the dial plate picture to thepointer recognition module to read a pointer numerical value. Meanwhile, the picture compression module compresses the dial plate picture, and meter reading and the dial plate picture are transmittedthrough the wireless transmission module. The illumination module provides local active high-brightness white light illumination. Wiring construction is not needed, meter data collection is intelligent, dial plate pictures and manual on-site meter reading can be provided as required, the intelligent and efficient characteristics of transformer substation meter inspection are remarkably improved.Meanwhile, manual later-period rechecking and checking means are supported, and the correctness of meter reading is guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of measurement and testing for transmitting and outputting visible indications of measured values, and in particular relates to an intelligent GIS pressure gauge wireless direct reading device. Background technique

[0002] In the gas insulated substation GIS (Gas Insulated Substation), most of the electrical equipment is directly or indirectly sealed in the pipe tree composed of metal pipes and casings, and no switches, lines and terminals can be seen from the outside. The interior of the pipeline tree uses SF6 gas as the insulating medium, and all high-voltage electrical components are sealed in grounded metal cylinders. In order to ensure the reliability of the operation of high-voltage electrical components, various indicators must be monitored frequently, especially the SF6 gas must meet the relevant standards. The staff judges whether the inert gas SF6 in the GIS pipeline tree is normal by observing t...
