In recent years, with the reform and the development of China and the continuous improvement of the living standard of people, motor vehicles, especially cars, have more and more entered families of common people, and the number of parking spaces is increased to be limited, so that the parking of the vehicles is more and more difficult.
In some outdoor parking lots, the parking spaces are numerous, the parking spaces are complex in distribution, the turnouts in the parking lots are many, and for vehicles entering the parking lot, an empty parking space is searched for parking as if no flies are used, and the empty parking space is found and the vehicles are parked at the empty parking space. In this way, the driver can look for the empty parking space blindly, and we believe that the mind of the driver is urgent when looking for the empty parking space. Therefore, the outdoor parking space detection equipment becomes very important, and the prior art of outdoor parking space monitoring at present mainly comprises a geomagnetic detector or an ultrasonic and geomagnetic dual-function detector. A geomagnetic sensor is one method of determining whether or not a vehicle is present by detecting a change in the magnetic field of the earth around the geomagnetic sensor. The geomagnetic detector can be on some sites, due to the existence of underground passages, such as subways, tunnels and the like, when vehicles pass through, the induction value of the geomagnetic can also be correspondingly changed, so that misjudgment is caused, and the error rate of the geomagnetic detector is high, and according to the actual condition that the geomagnetic detector is adopted in the project which is already put into use, the error rate of the geomagnetic is generally about 3%, and the error rate of the ultrasonic and geomagnetic dual-function detector is lower, but the general ultrasonic and geomagnetic dual-function detector is or is integrally buried under the ground, so that the failure of ultrasonic detection can be caused as long as the rain is accumulated, in addition, the geomagnetic detector is integrally buried under the ground, so that the construction is inconvenient, and particularly, when batteries are replaced in the later period, the detector needs to be integrally dug out, so that the geomagnetic detector is relatively complex; or the detector is mounted on the ground completely, although the detector is convenient to mount, the whole detector is exposed outside, so that the battery can run out quickly in a severe cold and hot environment, and the service life of the battery is greatly shortened.
