Embodiment 1

[0030] The purpose of this embodiment is to provide a construction vehicle proximity induction alarm device.

[0031] The solution described in this disclosure is based on the distance calculation method of the induced electric field intensity. First, the principle of the distance calculation method for the induced electric field intensity is explained. When the distance to the line is the same, the electric field intensity has a unique value, which can accurately calculate the distance of the vehicle. The distance of the line has high reliability; when the construction vehicle is close to the line, the form of the electric field induced on the sensor will be as follows: figure 1 as shown ( figure 1 Middle δ is the interlayer distance between the wire surface and the alarm distance threshold; E is the electric field intensity); the uniform electric field between the two conductive layers will be used as an important parameter to evaluate the distance from the high-voltage char...

Abstract

The invention provides a construction vehicle near-electric induction alarm device which is designed based on the principle that the alarm distance is determined according to the electric field intensity; the device comprises a signal receiver, an output alarm and a power module. The signal receiver and the output alarm are separated by adopting a frequency hopping wireless alarm design, and signal transmission is carried out in a wireless transmission mode; the signal receiver and the output alarm are respectively connected with the power supply module through wires. According to the scheme,the frequency hopping wireless transmission technology is adopted, continuous communication can be achieved by avoiding an interference channel, and the transmission stability is improved; the problemthat the safety distance between a construction vehicle and a power supply line cannot be actively warned is fundamentally solved, the warning correct rate reaches 100%, and the labor intensity of electric power workers and the uncontrollable tripping current situation are greatly relieved.

Description

technical field [0001] The disclosure belongs to the technical field of near-electricity alarms for vehicles, in particular to a near-electricity induction alarm device for construction vehicles. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] According to statistics, among the damage accidents of power facilities that occur at this stage, the proportion of accidents involving damage to power facilities by operating vehicles ranks first; most of the accidents caused by crane operations are caused by accidental collisions with live lines and equipment, and the consequences are quite serious. When the working vehicle violates the live line distance, the high-voltage line will discharge the metal parts in the air. The current and arc generated by the discharge are very destructive, and the burns are sometimes fatal. In addition, if the powe...
