Abstract
The utility model relates to an underground metal detector, and the main technical characteristics are that the underground metal detector mainly comprises a probe and a control device, and the control device comprises a power supply module, an intelligent microcontroller, a high frequency oscillator, an oscillation detector, an audio controller, a power amplifier and an information output module. By utilizing an electromagnetic induction technology to detect metals, when a metal is detected, the alternating magnetic field of a detection area is interfered, the balance state of the probe is destroyed, so that an alternating voltage having a weak change is outputted from the output end of a detection coil, a voltage signal passes through the intelligent microcontroller, and an alarm trigger signal is sent from a corresponding port of the intelligent microcontroller to a trigger end of an execution circuit of the audio controller after compared and judged by a management program, so that an alarm is given automatically to detect an object containing metal. The utility model is reasonable in design, and by using the underground metal detector of the utility model, the problems are solved that the anti-interference capability is poor, the sensitivity is low, the measurement precision is not high, the performances are not stable, etc., so that the underground metal detector can play roles normally, and has the advantages of intellectualization, anti-interference, high sensitivity, accurate positioning, strong resolution, wide detection range, convenient and simple operations, etc.
Description
Technical field
The utility model belongs to the detector technology field, especially a kind of underground metal detector.
Background technology
Metal detector is a kind of instrument that is used for surveying metal specially; Except being used to survey the land mine that metal shell or metal parts are arranged; Can be used to survey hidden in wall electric wire, be embedded in underground water pipe and cable, even can undergroundly hunt for treasure, find to be imbedded in underground metal object.It also is widely used in the fields such as antitheft inspection, archaeology, mine locating of safety inspection, the factory and enterprise of various conventions center, exhibitions venue, stadiums, public security organs and prison system and public place of entertainment at present except militarily using.Metal detector can be divided into following several kinds by the difference in its function and application field: channel-type metal detector (abbreviation detector gate), hand-held metal detector, potable metal detector, desk-top metal detector, industrial metal detector and metal detector under water.
Summary of the invention

5, the utility model is reasonable in design; Solved poor anti jamming capability, problems such as sensitivity is low, measuring accuracy is not high, unstable properties; Make underground metal detector can normally bring into play its effect; Have intelligent, anti-interference, highly sensitive, accurate positioning, resolving power is strong, advantage such as investigative range is wide, easy and simple to handle, but widespread use.
Description of drawings
Fig. 1 is the fundamental diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model instance is done further detailed description:
A kind of underground metal detector; Mainly comprise probe and control device part; The control device part is as shown in Figure 1, comprises formations such as power module, intelligent microcontroller, high frequency oscillator, oscillating detector, Audio Controller, power amplifier and message output module, and high frequency oscillator, oscillating detector, Audio Controller, power amplifier and message output module link to each other with intelligent microcontroller respectively; High frequency oscillator also is connected with oscillating detector; Audio Controller, power amplifier and message output module link to each other successively, and power module is given other each module for power supply, and probe mainly is made up of detecting coil.
The intelligence microcontroller connects high frequency oscillator; The vibration that oscillator produces is through the oscillating detector frequency division, behind the power amplifier power amplifier; Feedback is transported to detecting coil, and in order to produce alternating magnetic field, alternating magnetic field is induced signal in detecting coil; But when composite signal was zero, probe was in equilibrium state; Because of metal all has magnetic and electric conductivity, when metal object is passed through detecting area, will produce former alternating magnetic field and disturb, when no extraneous metal passed through, its message output module was in equilibrium state; When metal passed through, the detecting area alternating magnetic field was interfered, and had destroyed the equilibrium state of probe; Thereby the output terminal that makes detecting coil has the alternating voltage output of a faint variation; This faint voltage signal is through intelligent microcontroller, through supervisory routine relatively, warning trigger pip after judging, be issued to the trigger end of Audio Controller executive circuit by intelligent microcontroller corresponding port; Thereby report to the police automatically, the object that will contain metal detects.
It is emphasized that; The described embodiment of the utility model is illustrative; Rather than it is determinate; Therefore the utility model is not limited to the embodiment described in the embodiment, every by those skilled in the art according to other embodiments that the technical scheme of the utility model draws, belong to the scope of the utility model protection equally.
