Abstract
The present utility model relates to a magnetic induction vehicle detector based on a spontaneous magnetic field, and the detector is used for detecting whether vehicles are parked in a certain space or not. The detector comprises a magnetic field sensor, a microprocessor connected with the magnetic field sensor, and a stable magnetic field generator, and the stable magnetic field generator is arranged within a space scope detected by the magnetic field sensor. By adopting the detector, problems that as the field intensity of the geomagnetic field is weak, detection errors of the prior magnetic induction vehicle detector are easy to occur, and detection accuracy of the magnetic induction vehicle detector is enhanced.
Description
Technical field
The utility model relates to the magnetic strength vehicle detector whether storing cycle is arranged for detection of a certain locus.
Background technology
The magnetic strength vehicle detector is widely used in the stopping guide and charging administration system on indoor and outdoor parking lot, parking stall.Existing magnetic strength vehicle detector all is whether have vehicle enter this locus by the disturbance of detection vehicle to the magnetic field of the earth in a certain space if differentiating.Yet because the field intensity in magnetic field of the earth is fainter, therefore existing magnetic strength vehicle detector detects mistake easily.
The utility model content
The purpose of this utility model is the deficiency for above-mentioned existing magnetic strength vehicle detector, and a kind of magnetic strength vehicle detector based on spontaneous magnetic field is provided, to improve the Detection accuracy of magnetic strength vehicle detector.
The main technical schemes that the utility model is taked is, a kind of magnetic strength vehicle detector based on spontaneous magnetic field, comprise magnetic field sensor and the microprocessor that is connected with magnetic field sensor, also comprise the stabilizing magnetic field generator, described stabilizing magnetic field generator is positioned at the spatial dimension that magnetic field sensor is surveyed.
As preferred forms, described stabilizing magnetic field generator is permanent magnet.The stabilizing magnetic field generator that is arranged in each parking space is at least one.
The utility model has the advantages that, utilize the magnetic field of stabilizing magnetic field generator enhancing location to be detected, improved the Detection accuracy of magnetic strength vehicle detector.
Description of drawings
Fig. 1 is the general structure synoptic diagram of the utility model embodiment;
Fig. 2 is the position view of the utility model embodiment.
Embodiment
Fig. 1 is general structure synoptic diagram of the present utility model.
A kind of embodiment based on the magnetic strength vehicle detector in spontaneous magnetic field.As shown in Figure 1, comprise magnetic field sensor and the microprocessor that is connected with magnetic field sensor.Microprocessor is in order to receive and to process the magnetic field variation signal of magnetic field sensor.In the spatial dimension that magnetic field sensor is surveyed, be placed with the stabilizing magnetic field generator.The stabilizing magnetic field generator preferably adopts permanent magnet, for example Nd-Fe-B permanent magnet.Certainly, the utility model is not got rid of the employing solenoid as the stabilizing magnetic field generator yet.
Embodiment shown in Figure 1 also comprises the data transmission module that is connected with microprocessor, in order to the result of microprocessor is transferred to the central processing system of last layer in wired or wireless mode, to carry out higher level processing.Certainly, for some mini-systems, data transmission module is not necessary, can directly by microprocessor output final process result, for example export certain demonstration information.Embodiment shown in Figure 1 also is provided with battery module.Battery module neither be necessary, can decide according to the practical service environment of product.
Fig. 2 is the position view of the utility model embodiment.As shown in Figure 2, at parking space some parking stalls are arranged, the middle part, ground in each parking stall arranges a permanent magnet 1, and magnetic field sensor 2 is set near permanent magnet 1.Certainly, also can a more than permanent magnet be set according to place situation and vehicle condition in the parking stall, such as for large-scale parking stall and oversize vehicle, can two or more permanent magnets be set the front and back position in each parking stall, to improve the accuracy to vehicle identification.
