Technical field:
The present invention relates to a kind of detection instrument, particularly a kind of for surveying the hand-held detection instrument at the besieged object of medium.
Background technology:
At present domestic and international existing metal detector, mainly contain inductance type, condenser type and electromagnetic field type metal detector, because its accuracy of detection is low, a little less than antijamming capability, capacitance metal detector particularly, be subject to on-the-spot the interference greatly, the measurement result distortion, easily produce wrong report and fail to report phenomenon, therefore above-mentioned detector only is useful in specific occasion, as factory's smelting ore deposit industry, and function singleness, only have a kind of function of metal detection, can't survey the objects such as alternating current, wooden frame, therefore need to be improved.
Summary of the invention:
The object of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of detection accurately, reliably, antijamming capability is strong, multiple functional, can be used for surveying the hand-held detection instrument of the objects such as metal, alternating current, wooden frame and plastics.
Purpose of the present invention is achieved through the following technical solutions:
A kind of hand-held detection instrument, comprise a housing, described housing one end forms hand grip portion, the other end is set to detection section, described housing is provided with battery in hand grip portion, described housing is provided with circuit board in detection section, light-guiding pillar and fixed mount, CPU is installed on circuit board, transmitting coil, receiving coil, light emitting diode and buzzer siren, described housing is provided with liquid crystal display and control panel in detection section outside surface, described CPU one has phase-detection, the processor of identification function, described control panel is electrically connected to the input end of CPU, described light emitting diode, buzzer siren and liquid crystal display are electrically connected to the output terminal of CPU respectively, described transmitting coil is electrically connected to the output terminal of CPU by one drive circuit, described receiving coil is electrically connected to the input end of CPU by a signal amplification shaping circuit.
Described light-guiding pillar adopts transparent plastic construction, and it has at least an end to expose to housing.
Described light emitting diode can be one or more, and it provides light source for described light-guiding pillar.
Described light emitting diode can be the light source that described light-guiding pillar provides red, green two kinds of different colours.
Described light-guiding pillar, transmitting coil and receiving coil distribute from inside to outside successively, and three's concentric arranges.
Beneficial effect of the present invention is:
1, detection method: adopt advanced phase shift detection technique (phase-detection), there are the characteristics such as highly sensitive, that antijamming capability is strong.
2, detection technique is advanced, ripe, and specificity, highly sensitive, adopted phase-detection, and accuracy of detection and reliability aspect are effectively guaranteed.
3, function is more: except detectable metal (magnetic and non magnetic), and objects such as detectable alternating current, wooden frame, plastics also.
In addition the present invention also incorporates human oriented design, as: energy-saving type automatic shut-off function (after 5 minutes); The small signals amplification Presentation Function; LCD dynamically shows, different sound warnings of hummer etc.
The accompanying drawing explanation:
Below with reference to the accompanying drawings the present invention is described in further detail.
The master that Fig. 1 is hand-held detection instrument of the present invention looks schematic diagram.
The decomposing schematic representation that Fig. 2 is hand-held detection instrument of the present invention.
The circuit block flow diagram that Fig. 3 is hand-held detection instrument of the present invention.
Embodiment:
As shown in Figure 1 to Figure 3, the described a kind of hand-held detection instrument of the embodiment of the present invention, comprise a housing 1, and housing 1 is covered and formed by bottom 11 and cover 12, and housing 1 one ends form hand grip portion 10, and the other end is set to detection section 20.Housing 1 is provided with battery 2 in hand grip portion 10, housing 1 is provided with circuit board 3, light-guiding pillar 4 and fixed mount 5 in detection section 20, CPU, transmitting coil 6, receiving coil 7, light emitting diode and buzzer siren are installed on circuit board 3, and housing 1 is provided with liquid crystal display 8 and control panel 9 in detection section 20 outside surfaces.CPU one has the processor of phase-detection, identification function, control panel 9 is electrically connected to the input end of CPU, light emitting diode, buzzer siren and liquid crystal display 8 are electrically connected to the output terminal of CPU respectively, transmitting coil 6 is electrically connected to the output terminal of CPU by one drive circuit, and receiving coil 7 is electrically connected to the input end of CPU by a signal amplification shaping circuit.
This detection instrument mainly utilizes electromagnetic induction principle, when having alternating current to pass through transmitting coil 6, this coil will produce stable magnetic field, this magnetic field energy produces vortex flow in the metallic object induced inside, this vortex flow produces changes of magnetic field conversely in receiving coil 7, this variable signal is after amplification and rectification circuit is processed, again after digital phase detection, CPU process, output signal is through liquid crystal display 8 demonstrations, lumination of light emitting diode, buzzer siren ring, allow the user can judge the situation of testee, and can determine relative position and the distance of testee.
