Detailed Description
The invention will be further described with reference to the accompanying drawings:
as shown in fig. 1 and 2, the power supply operation safety detection device comprises an electric wire 1, an alarm 2, a wireless parameter calibration device 3 and a lifting device 5, wherein the lifting device 5 is provided with an electric field detection device, the electric field detection device comprises an electric field sensor 4, a signal conditioning circuit 7, a first single chip microcomputer unit 8 and a wireless transmitting unit 6, the lifting device is arranged on a detection vehicle, the alarm 2 is arranged in the detection vehicle, the wireless parameter calibration device 3 is connected with the first single chip microcomputer unit 8 through a wireless network, the electric field sensor 4 sends the collected electric wire signal to the signal conditioning circuit 7, the conditioned electric signal is sent to the first single chip microcomputer unit 8, then the signal is sent to a wireless receiving unit 10 through a wireless transmitting unit 6, the wireless receiving unit 10 sends the signal to a second single chip microcomputer unit 11, and the alarm 2 is connected with the second single chip microcomputer unit.
The wireless receiving unit 10 and the second singlechip microcomputer unit 11 are both arranged in the detection vehicle.
The second singlechip unit 11 is also connected with a display unit 9.
The wireless parameter calibration equipment comprises a notebook computer and an insulating rod with scales.
An electric field sensor is installed at the near-electric end which is most easily close to a power line, and a signal is converted into a voltage signal which is in direct proportion to the electric field intensity by utilizing the electrostatic induction principle. The alarm device receives alarm information through the wireless communication system to realize an alarm function. And the calibration equipment is used for remotely calibrating the relation between the measured distance and the detected voltage through wireless communication so as to determine the voltage value corresponding to the safe distance under the current voltage level.
