Embodiment 1

[0068] For engineering construction, the proximity electric warning must be easy to install, stable and reliable, with low false alarm rate and no false alarm, so the spherical sensor 121 and mechanical circuit are selected to ensure the sensitivity and accuracy of the induction signal. Therefore, the proximity electric early warning circuit provided by the present invention must satisfy the reliability of detecting high-voltage electric signals while simplifying the circuit structure and reducing the cost.

[0069] In conjunction with the figures, the operation process of the present invention is as follows. Correctly be installed on the suspension arm of mechanical vehicle after the sensing device 1 of near electric prewarning device is fully charged, and this device is that binding band fixes, and is convenient to disassemble. Turn on the power module switches 14 and 27 to start working. At the moment of power on, the blue indicator light 222 will flicker once, which will i...

Abstract

The invention discloses an electricity-approaching early-warning system for mechanical vehicles. The system comprises an electric field signal sensing device (1) arranged on the outer side of a mechanical vehicle and used for detecting the change of an electric field; and an indicating and alarming device (2) arranged on the operating table of the mechanical vehicle and used for indicating and alarming purposes. The electric field signal sensing device (1) is connected with the indicating and alarming device (2) through a wireless signal. According to the technical scheme of the electricity-approaching early-warning system for mechanical vehicles, when a construction mechanical vehicle approaches a high-voltage power line, the photoelectric alarm is sent out. Therefore, the occurrence of the accidents of a high-voltage transmission line can be reduced or avoided.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment, in particular to a mechanical vehicle near-electricity warning system that can perform photoelectric alarms when the mechanical vehicle is close to a high-voltage line during construction. Background technique [0002] In recent years, with the increasing development of industrial production, the construction scale of the power grid has developed by leaps and bounds. At the same time, due to negligence in operation, high-altitude construction machinery is too close to high-voltage transmission lines. , Some will cause large-scale power outages, causing serious losses to national economic production, and also have a great impact on people's activities. [0003] Mechanical engineering vehicles repeatedly touch high-voltage transmission lines during the construction process. The reason is not only the negligence of construction operators, but also the lack of necessary early warning pro...
