Device for monitoring distance between object and danger source in overhead work

Abstract

The invention relates to a device for monitoring a distance between an object and a danger source in overhead work. A distance measuring module is composed of five HC-SR04 ultrasonic sensors. The maximum measuring angle of each sensor is 60 degrees and the distance between the object and the danger source is measured by using an ultrasonic distance measuring principle. A signal output end of an analysis control module is connected with a signal input end of an alarming promotion module; the analysis control module is used for processing data acquire by the distance measuring module and comparing the data with a pre-set safety distance; if the data are close to or less than the safety distance, the alarming promotion module is triggered to work. Wireless transmission modules are mounted on the distance measuring module and the alarming promotion module respectively, so that communication functions of the two devices are realized. With the adoption of the device for monitoring the distance between the object and the danger source in the overhead work, a worker can grasp the distance between the object and the danger source in real time, so that the safety of the overhead work is greatly improved.

Description

technical field [0001] The invention relates to a distance monitoring and alarming device, in particular to a device for monitoring the distance between an object and a danger source in high-altitude operations. Background technique [0002] At present, most power grid equipment is erected at high altitude, so when constructing, maintaining and repairing power grid equipment, workers often need to work at high altitude. Working at heights is a relatively dangerous operation method. In addition to ensuring that the staff and the tools used do not fall vertically, it is also necessary to ensure that the staff and the tools and tools used have sufficient safety distance from the source of danger in the horizontal direction. Dangerous sources include hot objects, charged objects, and objects that may move. According to the requirements of the "State Grid Electric Power Safety Work Regulations", the distance between staff and large equipment and the live part must be greater tha...

AI Technical Summary

Problems solved by technology

At present, the distance between the staff and the live parts is mainly judged by the staff's feeling and experience, and there is no special equipment for accurate measurement and real-time monitoring, which has brought serious hidden dangers to safe production
