Abstract

The utility model belongs to the measurement instrument field, especially to an intelligent magnetic induction instrument used for detecting the position of a magnet, comprising a processing unit, a magnetic resistance sensor, a power supply unit, an acousto-optic alarm unit and a display unit. A demagnetization unit used for demagnetizing the magnetic resistance sensor and a reset unit used for resetting the state of the magnetic resistance sensor before measurement are also arranged between the processing unit and the magnetic resistance sensor, and demagnetization and reset buttons are arranged on the panel of the instrument correspondingly. The intelligent magnetic induction instrument of the utility model is simple in structure, and is convenient in operation when carries out multiple continuous measurements by arranging the demagnetization and reset buttons, without needing to start up again every time to carry out the reset operation of the sensor. Because the intelligent magnetic induction instrument is mainly used for the magnet position detection, less concerning the magnetic field intensity accuracy value nearby a magnet; and compared with the conventional magnetic induction instrument, the internal structure of the magnetic induction instrument enables the units to be saved, such as a noise reduction unit, a filter unit, etc., so that the cost of the intelligent magnetic induction instrument is lower.

Description

Intelligence sense magnetic appearance
Technical field
The utility model belongs to the surveying instrument field, relates in particular to a kind of intelligence sense magnetic appearance that is used to detect magnet positions.
Background technology
Whether sense magnetic appearance exists the instrument big or small with magnetic force as a kind of magnet of measuring, and in daily life and commercial production, has obtained using widely.The general structure of existing sense magnetic appearance is more complicated all, for the size in the magnetic field of accurately measuring target to be measured, in the set inside of sense magnetic appearance a large amount of components and parts be used for noise reduction, filtering, relatively wait operation, such sense magnetic appearance cost is higher.In existing application, such application scenario is arranged, be exactly the definite size that need not know magnetic field, thereby only need to confirm the position of magnet through near the peak value of the magnetic field intensity measurement target.In this kind application, though existing sense magnetic appearance also can achieve the goal, cost is higher, need a kind of simple in structure, cost is low, the intelligence sense magnetic appearance of simple operation.
Summary of the invention
The utility model provides a kind of simple in structure, simple operation, intelligence sense magnetic appearance that cost is low for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: intelligence sense magnetic appearance comprises processing unit, magnetoresistive transducer, power supply unit, acousto-optic warning unit and display unit; Between said processing unit and magnetoresistive transducer, also be provided with and be used for before measuring for the demagnetization unit of said magnetoresistive transducer demagnetization and be the reset unit of said magnetoresistive transducer reset mode, on instrument panel, correspondingly be provided with the demagnetization SR.
The utility model can also adopt following technical scheme:
Also be provided with the zero clearing unit that is used for environmental magnetic field intensity is set at reference zero in the said processing unit, on instrument panel, correspondingly be provided with reset button.
The control chip of said processing unit adopts single-chip microcomputer.
Said magnetoresistive transducer is installed in and apparatus subject mutually independently on the probe, and said probe links to each other with apparatus subject through data line.
Said power supply unit comprises lithium ion battery.
Advantage and the good effect that the utlity model has are: owing to adopted above-mentioned design, the utility model is simple in structure.The setting of demagnetization SR makes the simple operation when carrying out repeatedly continuous coverage of sense magnetic appearance, need not all start shooting again at every turn and carry out the reset operation of sensor; Because this intelligence sense magnetic appearance is mainly used in the detection of magnet positions, near the exact value of the magnetic field intensity less concern magnet, its inner structure has been lacked unit such as noise reduction, filtering than heritage magnetic appearance, thus cost is lower.
Description of drawings
Fig. 1 is the structured flowchart of the utility model.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, the utility model comprises processing unit, magnetoresistive transducer, power supply unit, acousto-optic warning unit and display unit.Between processing unit and magnetoresistive transducer, also be provided with and be used for before measuring for the demagnetization unit of said magnetoresistive transducer demagnetization and be the reset unit of said magnetoresistive transducer reset mode, on instrument panel, correspondingly be provided with the demagnetization SR.The control chip of processing unit adopts single-chip microcomputer.Also be provided with the zero clearing unit that is used for environmental magnetic field intensity is set at reference zero in the processing unit, on instrument panel, correspondingly be provided with reset button.Magnetoresistive transducer is installed in and apparatus subject mutually independently on the probe, and this probe links to each other with apparatus subject through data line.Power supply unit comprises lithium ion battery.
The course of work of this instance: intelligence is felt the start of magnetic appearance; Single-chip Controlling demagnetization unit and reset unit are that magnetoresistive transducer demagnetizes automatically and resets the initialization state; Select a bit near the environment of measurement target; Press reset button after device registration to be shown is stable, this moment processing unit with this value storage in its inner storer, as the measurement zero point of follow-up measurement.The probe placement that will have magnetoresistive transducer afterwards is to target proximity to be measured; Processing unit will be handled and be shown on the display the magnetic field value at this place, and meanwhile, this numerical value compares with an empirical data of setting in advance; If exceed empirical data; There is magnet in proof near measurement target, processing unit control acousto-optic warning unit carries out sound and light alarm, promptly the alarm lamp on the instrument panel flash, the hummer sounding.When needs were measured next impact point continuously, the demagnetization SR that only need press on the instrument panel was the magnetoresistive transducer demagnetization and recovers the initialization state, pressed reset button setting measurement zero point afterwards, repeated above-mentioned measuring process.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
