In the present embodiment, the Voltage stabilizing module is LM7805 5v voltage-stablizers.
In the present embodiment, the battery is 4 section 5# dry cells.
Preferably, the buzzer uses general passive buzzer.
Particularly, in the present embodiment, the inductance detection principle of LDC1314 inductance sensors is electromagnetic induction principle.
Plus an alternating current in PCB coil, alternating electromagnetic field will be produced around coil, at this moment if metal object enters this
Individual electromagnetic field then can produce vortex in metal object surface（Induced-current）.Eddy current is with the direction of the winding current on the contrary, vortex
The induction field of generation is in opposite direction with the electromagnetic field of coil.Vortex is the distance of metal object, size, the function of composition.
The opposing magnetic field that vortex is produced is coupled with coil, is like with the presence of another secondary coil.So LDC1314's
Coil is as primary coil, and eddy current effect is formed a transformer as secondary coil.Because the mutual inductance of transformer is made
With can be to detect the parameter of secondary coil in this side of primary coil.

Vortex on circle can change the output parameter of sensor, device so as to judge electric wire position.When use device is detected, by device
Rostral anterior close to metope, three coils are parallel with metope, make device slowly movement progressively scan metope, go detection wall under
Square electric wire.MSP430F5529 single-chip microcomputers read the output parameter of sensor, by carrying out real time contrast with preset value, once it is defeated
Go out parameter change, device is that judgement detects electric wire.When the coil labeled as in is close to electric wire, the vortex on coil can occur
Change, so as to change the output parameter of sensor, single-chip microcomputer reads output parameter change, that is, judges electric wire where coil
Position below.Similarly, when labeled as left and right coil close to electric wire, device is that can determine whether electric wire residing for left and right coil
The lower section of position.
In the present embodiment, electric wire has many different materials such as copper core, aluminium core, and the influence to induction coil is different
's.Device starts before detection, it is necessary to which Pre-handoff is directed to the preset value of different metal setting to improve detection accuracy.On handle
Button is used to control wall detection device, and one hand can just be operated.Device is after electric wire position is judged, the honeybee on indicating module
Ring device can send sound.Electric wire present position is shown on TFT screens.User will mark walking for electric wire in wall on the wall
To, it is necessary to hand-held device makes it press close to metope, slowly mobile device finds electric wire according to the prompting on TFT screens, and with note
The position that number pen mark is found, the point found is linked up, it is possible to draw trend of the electric wire in wall.TFT screens also can
