Live working safety early warning system

Abstract

The invention discloses a live working safety early warning system which includes a sign data monitoring device worn on a live working person and used for collecting sign data of the live working person in operation; a safety distance monitoring device located on a tower pole and used for obtaining the sign data of the live working person from the sign data monitoring device, monitoring whether the live working person exceeds an alarm area, and giving an alarm when the live working person exceeds the alarm area or the sign data is abnormal. The live working safety early warning system automatically gives real-time warning on live working, improves the accuracy and real-time performance of safety distance detection, and ensures the safety of live working person.

Description

technical field [0001] The invention relates to the field of live overhaul and maintenance of power transmission and transformation projects, in particular to a safety early warning system for live work. Background technique [0002] The safe distance for live work refers to the minimum air distance that should be kept between the ground potential worker and the charged body or the equipotential worker and the grounded body in order to ensure personal safety. The basic principle for determining the minimum safety distance is to add a reasonable human activity increment on the basis of the minimum electrical clearance distance, which is the most effective measure to ensure work safety [0003] In order to reduce investment, the existing power transmission and transformation projects will only increase the margin of the air gap appropriately when designing. In the process of live work, the distance between the ground potential worker and the charged body or the equipotential ...

AI Technical Summary

Problems solved by technology

In the process of live work, the distance between the ground potential worker and the charged body or the equipotential worker and the grounding body is constantly changing, which may cause the worker to exceed the corresponding safe working area and cause a safety accident

Because the operator cannot accurately locate each part of the body when working on the wire or on the cross arm; and the live work is intense, it is not suitable to carry heavy and large monitoring equipment, so there is no reliable means to monitor the live work. process monitoring

At present, the safety of live-line work mainly depends on the supervision of dedicated guardians with rich practical experience in live-line work and the consciousness of operators. However, there are two problems in this kind of supervision: one is that the dedicated guardians rely entirely on their own work experience 1. The personal status determines the safe distance by visual inspection, which has a large supervisory factor. At the same time, the responsible guardian will also be affected by objective factors such as visual angle and external environment, and cannot accurately judge the existing distance; second, at the job site, Especially in the field of power transmission and live operation, the operator and the dedicated guardian will be separated by a certain distance, causing the dedicated guardian to be unable to intervene in real time on the actions of the operator, and there is a certain degree of delay in the instruction
