Charged body distance measurement and alarm device based on combination of electric field and radar

Abstract

The invention discloses a charged body distance measurement and alarm device based on combination of electric field and radar. A detection part comprises an electric field intensity measuring module, a radar ranging module, a signal conditioning circuit, a first single-chip microcomputer, and a wireless data sending module. An alarm part comprises a wireless data receiving module, a second single-chip microcomputer, and a sound-light alarm module. The device measures the electric field intensity at the location thereof and the distance between the device and a surrounding object in real time, compares the electric field intensity and the distance with corresponding thresholds respectively, judges whether there is a need for alarm and the alarm level, and gives a sound-light alarm to remind the staff to pay attention. The device is simple in installation, makes judgment quickly and accurately, and can effectively protect the safety of operation vehicles and personnel.

Description

technical field [0001] The invention relates to a distance measurement and alarm device for a charged body, in particular to a distance measurement and alarm device for a charged body based on the combination of electric field and radar. Background technique [0002] High-altitude construction machinery too close to overhead transmission lines will cause line short-circuit tripping accidents, and some will cause large-scale power outages, causing serious losses in national economic production and greatly affecting people's lives and social activities. Investigating the reasons for its occurrence, apart from the major accidents of the operators, there are no due reminders on whether the transmission lines are live, whether the construction equipment enters the high field strength area, and whether it is close to the minimum safe distance stipulated in the regulations.

[0002] High-altitude construction machinery too close to overhead transmission lines will cause line short-circuit tripping accidents, and some will cause large-scale power outages, causing serious losses in national economic production and greatly affecting people's lives and social activities

Investigating the reasons for its occurrence, except for the major accident of the operator, there is no due reminder whether the transmission line is live, whether the construction equipment enters the high field strength area, and whether it is close to the minimum safe distance stipulated in the regulations.

In particular, construction workers outside the power system often do not have the concept of a safe distance when constructing near high-voltage power equipment, so accidents are inevitable

[0003] At present, anti-collision high-voltage line devices are rarely used when cranes are working near high-voltage lines. can only turn in one direction

Obviously, this method is time-consuming and laborious, and it is not suitable for most crane construction operations.
