Embodiment 1

[0038] Such as figure 1 , figure 2 , image 3 As shown, a hidden wire detection device is provided in this embodiment, including a device body 1, which is used as a basic carrier, which can be a circular shell, a square shell, etc., and includes signal processing in the device body 1 module, a display and alarm module, and a power supply module; the power supply module supplies power to the signal processing module and the display and alarm module respectively;

[0039] The input end of the signal processing module is connected with a signal acquisition module, the signal acquisition module is set as an electric field measurement sensor 3, and the electric field measurement sensor 3 is a sensor with good anti-electromagnetic interference capability and fast response speed. It can measure the transient electric field in the high-voltage power system, and can be widely used in the detection of electric field strength. It converts the electric field strength generated by the p...

Embodiment 2

[0045] Based on Embodiment 1, a hidden electric wire detection method is also provided in this embodiment, the method includes the following steps:

[0046] (1) Collect and convert the electric field intensity generated by the concealed electric wires into an electric signal by the electric field measuring sensor 3;

[0047] (2) Perform data processing and data storage after the electric signal is amplified, filtered, effective value conversion and analog-to-digital conversion, and obtain the electric field data value and the distance data value, and obtain the distance data value by the calculation formula E=U / d , where E represents the electric field strength and U represents the voltage;

[0048] In the actual operation process, the electric field measurement sensor 3 can be moved manually, for example: move the electric field measurement sensor 3 to the left, and observe the change of the electric field data value. If it gradually becomes smaller, it means that the hidden ...

Abstract

The invention discloses a concealed wire detection device and a detection method, comprising a device body, the device body includes a signal processing module, a display and alarm module, and a power supply module; the power supply module is used for the signal processing module and the display and alarm module Power supply; the input end of the signal processing module is connected with a signal acquisition module, the output end of the signal processing module is connected with the display and the alarm module, and the electric field data value and the distance data value are displayed in real time by the display and the alarm module, and when the electric field data value When the electric field threshold value is exceeded, the display and alarm module are driven to give an alarm, so as to achieve the purpose of determining the exact position of the transmission line laying.

Description

technical field [0001] The invention belongs to the technical field of circuit installation engineering, and in particular relates to a concealed wire detection device and detection method. Background technique [0002] Since the electric wires in buildings are basically laid secretly, that is, buried in floors, walls, beams, and columns, the direction of the lines cannot be obtained during decoration and maintenance, which brings great difficulties and even losses to decoration and maintenance. Therefore, a kind of device that can measure the laying position of electric wire seems very meaningful. Of course, in addition to being able to detect the above situations, it can also be used in all places where the position of the charged conductor needs to be detected. [0003] Since the 50HZ power frequency alternating current is transmitted in the circuit, a 50HZ electromagnetic field will be generated in the space around the line, and the closer to the line, the higher the el...
