Abstract
A plate multifunctional metal detector includes a controller and a sensor arranged above or below the object being detected, which are connected to each other through electrical wires. The sensor composes ring-shaped, cuboid-shaped or elliptical ring-shaped ferrite rack and winding. The utility model has the advantages of simple configuration, easy facture, high sensitivity, small sensor volume, no-easy awareness and wide applicability, and is appropriate for all metal detecting security check.
Description
Technical field
The utility model relates to the metal detection technical field, more specifically to a kind of safety detection device.
Background technology
At present, on the airport, places such as steamer, railway station all adopt metal detecting device, detect the metal that people carry, and prevent that the bad person from carrying the metal lethal weapon, destroy Environmental security, to safeguard people's property, life security.But the environment for use of these metal detecting devices is strict, can only be in indoor use.Chinese patent " a kind of door type metal detector ", the patent No.: 99212574.X, this utility model relates to a kind of door type metal detector, mainly form by oscillator, amplifier, detection head, detection one low level gating circuit and subsequent conditioning circuit, it is characterized in that: detection head is unshielded split type, transmitting coil and balancing unit receiving coil are installed in the both sides of sense channel respectively, and logistics will be subjected to an examination during by detecting area, and the object that is mixed with metal object is sent alerting signal.This metal detector is highly sensitive, resolution is high, antijamming capability is strong, need not shield, and saves material, cost is low, the cost performance height, and characteristics such as simple in structure, easy to install are arranged, the safety check department that is fit to very much customs, airport, station, harbour uses.But the inductor volume of the detecting device that uses is very big, and is in the both sides of inspected object, and the easy vision of people is found.
Summary of the invention
Technical problem to be solved in the utility model be overcome the deficiency of prior art and provide a kind of simple in structure, highly sensitive, the inductor volume is little, easy for installation and be difficult for the plate-type multifunctional metal detector of vision.
The utility model can take following technical measures to solve: a kind of flat metal detecting device, contain controller 1, inductor 2, controller 1 and be connected with inductor 2 electric wires, its structural feature is: inductor 2 be placed in object to be detected above or below.
Above-mentioned inductor 2 is made up of with coil 4 ferrite frame or epoxy plate skeleton 3, and coil 4 curls at ferrite frame or epoxy plate skeleton 3 skins.
Above-mentioned ferrite frame or epoxy plate skeleton 3 be in annular, cuboid or the oval ring any.
The induction sensitivity radius of above-mentioned inductor 2 is 0-50 centimetre.
Outstanding effect of the present utility model is:
1), the utility model is simple in structure, making is easy.
2), the utility model is highly sensitive, the inductor volume is little and be difficult for vision.
3), the utility model is can indoor and outdoor dual-purpose.
4), the utility model is applied widely, all genus will carry out the place of metal detection safety inspection all can adopt the utility model.
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of inductor 2.
Fig. 3 is the structural representation of the inductor 2 of embodiment 2.
Fig. 4 is the circuit block diagram of controller 1.
Embodiment
A kind of metal detecting device that has the miniature inductive device as shown in Figure 1 and Figure 2, contains controller 1, inductor 2, controller 1 and is connected with inductor 2 electric wires, inductor 2 be placed in object to be detected on or below.Inductor 2 is made up of with coil 4 ferrite frame or epoxy plate skeleton 3, and coil 4 curls at ferrite frame 3 skins.Ferrite frame or epoxy plate skeleton 3 are cuboids.The induction sensitivity radius of inductor 2 is 35 centimetres.
With embodiment 1, as shown in Figure 3, inductor 2 radiuses are 5 centimetres, are ferrite frame or epoxy plate skeleton 5 annulars, and coil 6 curls at ferrite frame or epoxy plate skeleton 5 skins.The induction sensitivity radius of inductor 2 is 35 centimetres.As shown in Figure 4, controller 1 is supplied with inductor 2 by the LC oscillator electromagnetic wave that to shake a frequency be several KHz, around inductor 2, produce a magnetic field, when the metal detection thing passes through magnetic field, in metal, produce eddy current, caused the magnetic field energy consumption of high-frequency ac electromagnetism thing, make a high-frequency current increase, measure the signal that electric current increases by detecting the loop differential, this electric current increase makes resistance produce the variation of voltage.Utilize this change in voltage, this variable is amplified, reach the purpose of sound, light warning by gating, filtering, anti-jamming circuit, amplifying return circuit, control loop.
Claims (4)
1, a kind of plate-type multifunctional metal detector contains controller (1), inductor (2), controller (1) and is connected with inductor (2) cable, it is characterized in that: inductor (2) be placed in object to be detected above or below.
