Embodiment Construction

[0007] The main control circuit of the device is installed inside the warning sign 1, a solar panel 2 is installed on the top of the warning sign 1, and a vertical pole 4 is fixed upward on the top of the warning sign support 3, and the distance from the top to the ground is not lower than 3M. There are swivel cameras5. The main control circuit includes a picture storage circuit, a contrast screening circuit, a warning output circuit and a GPRS wireless transmitting module. Its working principle is: under normal circumstances, the rotating camera 5 rotates once in 10 seconds, and takes images at a fixed angle of no less than 3 frames per week, and the upper half of each frame of images is stored as a low-density black and white bitmap; comparison and screening The circuit compares the bitmap of the upper half of each angle image with the bitmap of the same angle stored in the previous 1 minute, 10 minutes, and 30 minutes. If there is an abnormal change, it will store the panor...

Abstract

A dangerous voltage early warning reminder belongs to the technical field of maintenance and management of the power industry. A master control circuit of the reminder is mounted in a warning board, a solar cell panel is mounted on the top of the warning board, an upright rod is upwards fixed onto the top of a warning board support, the distance from the upright rod to the ground is not shorter than 3M, a rotary camera is mounted on the top of the upright rod, and the master control circuit consists of a picture storage circuit, a comparison screening circuit, a warning output circuit and a GPRS (general packet radio service) wireless transmission module. The dangerous voltage early warning reminder is applicable to regions, such as residential areas, roads and the like, with high personnel and vehicle density and high-voltage lines, and is a stereoscopic early warning reminder arranged out of a safety distance. When an article enters a monitoring plane, a voice prompt of the reminder gives out prompting sound and lamplight warning signals, and information is transmitted to a power supply maintenance duty room via the GPRS wireless transmission module. The reminder looks like the high-voltage warning board, is powered by a solar cell and works outdoors around the clock, and an effective warning effect is realized when the dangerous voltage early warning reminder is used with the warning board.

Description

technical field [0001] The invention belongs to the technical field of power supply management in the electric power industry. Background technique [0002] In many densely populated areas of our country, high-voltage power supply lines often pass through potential dangerous areas such as busy roads and some illegal buildings. Although under normal circumstances, whether vehicles or other moving objects are kept at a safe distance, accidents still happen. For this kind of danger, the usual practice is for the power supply management department to set up eye-catching warning signs nearby. However, due to people's numb thinking and fluke psychology, they often turn a deaf ear to the warning slogans, causing some electric shock accidents to happen from time to time. For this reason, if it is possible to automatically monitor dangerous areas without supervision and issue warnings in time, such risks can be greatly reduced. Contents of the invention [0003] The purpose of t...
