High-voltage transmission line construction distance early warning device and method

Abstract

The invention discloses a high-voltage transmission line construction distance early warning device and method, and the device comprises a measurement end and an alarm end, and the circuit structuresof the measurement end and the alarm end are installed in a shell and are powered by a power module. The electric field sensor at the measurement end is connected with the input end of a controller through a signal processing circuit, a distance measuring sensor is connected with the input end of the controller, and the controller is connected with a wireless transmission module; an alarm end wireless data transmission module is connected with the controller, a working mode setting key is installed on the machine shell and connected into the controller through a working mode setting module, the output end of the controller is connected with a voice control module and a light control module, the voice control module is connected with an alarm and a buzzer, and the light control module is connected with a light emitting diode. The measurement equipment and the alarm equipment which are of a split structure are arranged, the measurement equipment can be arranged at the top end of the construction equipment, the operator holds the alarm equipment by hand, long-distance detection and alarm are achieved and the working environment of large mechanical equipment is met.

Description

Technical field: [0001] The invention relates to construction auxiliary equipment, in particular to a high-voltage transmission line construction distance warning device and method thereof. Background technique: [0002] Tripping and electric shock accidents caused by construction machinery touching or being too close to high-voltage transmission lines occur from time to time. Such accidents seriously threaten the safe operation of the power grid, and may cause large-scale power outages, personal casualties, and equipment damage. Traditional solutions include setting up safety warning signs and setting up bamboo raft protection barriers, etc., which are mainly judged by visual inspection, and the accuracy is low. There is no corresponding prompt for whether the transmission line is live, whether the operator and the construction machinery enter the high field strength area. It is highly dependent on the experience and quality of operators and has poor reliability. [0003...
