Dangerous point warning device and warning method for power line operation site

Abstract

The invention discloses a dangerous point warning device for a power line operation site. The dangerous point warning device is composed of a microprocessor, a memory, an RFID radio frequency reader-writer, a power supply circuit and a shell. A miniature wireless network can be formed by the RFID radio frequency reader-writer and an external electronic device; the device is provided with a magnetwhich can control a magnetic control element in the power supply circuit so as to control the on-off of the circuit. A transmitting unit and a receiving unit of the RFID radio frequency reader-writerin the circuit and a power supply branch circuit of the memory circuit can be independently controlled to be switched on and off. The warning method comprises the steps of 1 manufacturing a dangeroussource type code on site, and writing the code and auxiliary information into the device; 2 arranging the warning device on the site; 3 receiving an inquiry signal, and sending a dangerous point typeand affiliated information; and 4 entering a dormant state after sending is finished. The beneficial effects of the invention are that an onsite danger source is marked in a mode of a wireless signalof an electronic device, and intelligent monitoring can be achieved.

Description

technical field [0001] The invention relates to the field of on-site safety monitoring and guarantee for power line operators. Background technique [0002] This dangerous point warning device and warning method adopts the Internet of Things, wireless communication and artificial intelligence technology as a whole, and the on-site safety recognizer carried by the on-site operators (has obtained a Chinese invention patent: "A Recognizer for Electric Power Safety Supervision") and identification method" Patent No.: ZL201410069508.7) and lay out according to the definition of on-site dangerous points to form a ring-shaped electronic warning area with the dangerous point as the original center, reminding the operators not to enter the dangerous area by mistake, so as to protect the personal safety of the operators Safety. [0003] In the power line accident operation site, in addition to the three important safety measures of power failure, power inspection, and grounding, ther...

AI Technical Summary

Problems solved by technology

[0004] 1. Different guardians have different understandings of the definition of on-site dangerous points, and the monitoring is not in place, so that some on-site dangerous points are overlooked

[0005] 2. The sense of responsibility of individual guardians is not strong, and the guardianship is not in place. The resulting personal casualties and equipment damage accidents have occurred many times in the past, causing huge damage to the power departments at all levels and the lives of employees.

Although the above-mentioned regulatory measures have played a certain warning role, the safety warning effect is not ideal due to factors such as inflexible on-site layout and lack of active pre-control functions.
