Multifunctional wall body detecting instrument

Abstract

The invention relates to the field of building structure detection, in particular to a wall body detecting instrument. The multifunctional wall body detecting instrument includes five parts: a first part is a water pipe detection circuit, and the water pipe detection circuit is composed of a capacitive sensor used for detecting a water pipe, a monostable trigger circuit and a mean value circuit which are connected with one another in series sequentially; a second part is an electric wire detection circuit, and the electric wire detection circuit is composed of copper pour, a high-impedance amplifying circuit, an impedance conversion circuit which are connected with one another in series sequentially; a third part is a metal detection circuit, and the metal detection circuit is composed of an emission winding, a current syntonic circuit, a difference receiving coil, an amplifying circuit, a filter circuit and a biasing circuit which are connected with one another in series sequentially; a fourth part is an auxiliary circuit, and the auxiliary circuit is composed of an infrared transmitter and an infrared receiver which are connected with each other in series sequentially; and a fifth part is a control circuit which comprises a controller. The first part, the second part, the third part, the fourth part are connected with the fifth part respectively and independently. The multifunctional wall body detection is compact in size, low in manufacture cost, simple in craftsmanship, and good in manufacture repeatability.

Description

technical field [0001] The invention relates to the field of building structure detection, and more particularly to a wall detector. [0002] Background technique [0003] During the home decoration inspection, the water pipes, wires, and metal reinforcement in the wall often have a certain impact on the construction, and even cause accidents, resulting in personnel and property losses. If the detection can be carried out before construction to find out the arrangement of water pipes, electric wires and metal reinforcement in the wall, the occurrence of relevant accident losses can be effectively prevented. [0004] In the current field of industrial control, there are sensors specially for objects such as metals and wires. For example, in the current industrial control field, in order to detect defects of metal parts, eddy current sensors are often used, and the eddy current sensors have good resolution and linearity. However, in the field of construction, the focus is o...
