Abstract

The invention discloses an online telemetering method of the reading of a mechanical SF6 gas density meter. The online telemetering method includes the image acquisition step, the image reading information recognition step and the reading step. Accordingly, the invention further discloses an online telemetering device of the reading of the mechanical SF6 gas density meter. The online telemetering device comprises an image acquisition unit, an image analyzing and processing unit and a reading end device, wherein the image acquisition unit acquires images of a dial of the mechanical SF6 gas density meter according to remote acquisition instructions, and the acquired images of the dial are digitalized into image signals to be output; the image analyzing and processing unit is connected with the image acquisition unit, receives and recognizes the image signals output by the image acquisition unit and extracts image reading information contained in the image signals; the reading end device is in remote data connection with the image analyzing and processing unit so as to receive the image signals and/or the image reading information transmitted by the image analyzing and processing unit. Through the method and device, the reading of the mechanical SF6 gas density meter can be telemetered online, and thus labor and time cost are saved.

Description

technical field [0001] The invention relates to a method and a device for online telemetry of a dial, in particular to a method and a device for online telemetry of a mechanical dial. Background technique [0002] SF 6 Gas has the characteristics of high dielectric strength and good arc extinguishing performance. It is the preferred insulating medium for high-voltage equipment and has been widely used in SF 6 High voltage circuit breaker, GIS, SF 6 Transformer, SF 6 equipment such as transformers. SF 6 Gas Density State is a measure of SF 6 Whether the degree of gas insulation meets the insulation requirements of the corresponding voltage level is one of the key parameters. Currently, mechanical pointer SF 6 The gas density meter becomes SF with its high reliability and low cost 6 Primary density measuring meter for gas insulated power equipment. However, with the development of computer technology, electronic technology, and software technology, the construction of...
