Safe work distance measuring and early-warning method of aerial lift device with insulated arm

Abstract

The invention relates to a safe work distance measuring and early-warning method of an aerial lift device with an insulated arm. Supersonic sensor are arranged in upper front, rear, left, right and lower positions of the arm respectively, power is supplied to different devices, and a minimal safe distance of early warning is set; a single-chip microcomputer STM32 is arranged to send range finding pulse signals to the supersonic sensors; a measuring-end device forwards measured distance data to an early-warning device in a console of the aerial lift device via a WiFi module; the early-warning device receives data via the WiFi module, received data is displayed on a display, and a minimal distance value is selected from the received data after processing; the minimal distance value is compared with the preset minimal safe distance value, and whether alarming is raised is determined; and the single-chip microcomputer STM32 emits an early-warning signal to drive an acousto-optic alarm and implements braking. The safe work distance measuring and early-warning method can improve the safety and reliability of maintenance, transmit range finding information stably, realize effective early warning, enable an operator to monitor the distance between the arm and power cables as well as the distance between the arm and a large transformer and the like in real time, and reduce power accidents.

Description

technical field [0001] The invention relates to a method for measuring and early warning the safe working distance of an insulated bucket arm truck, and relates to the fields of safety monitoring and wireless communication for maintenance of power stations and transformer substations. Background technique [0002] Insulated bucket arm truck is a commonly used maintenance auxiliary equipment. During the working process, the bucket arm needs to be lifted, retracted and other operations close to the live body. Affected by factors such as sight, there is a risk of getting too close to or touching the live body. Install wired monitoring equipment on it, because the working conditions of the bucket arm are complicated, there will be problems such as wiring difficulties and easy damage to the lines. The wireless ranging method can overcome the difficulty of wiring and other problems, and at the same time, it can make the arrangement of the ranging device more flexible, and meet the...
