Abstract
The invention discloses a method for sharing a magnetic field transmitting antenna and a parking lot system ground induction coil, including magnetic field emitting antenna, a commutation circuit, a remote sensing key and a remote sensing controller. In a normal state, a coil of the magnetic field emitting antenna is a parking lot system ground induction coil; when the parking lot system ground induction coil induces a metal foreign mater, the parking lot system ground induction coil sends an induction signal to the remote sensing controller, the remote sensing controller drives the commutation circuit to commutate the parking lot system ground induction coil into the coil of the magnetic field emitting antenna, the magnetic field emitting antenna emits a magnetic field signal, the magnetic field signal awakens the remote sensing key, the remote sensing key emits a radio frequency coding signal to the remote sensing controller, and the remote sensing controller analyzes and processes the radio frequency coding signal and then executes a corresponding action. According to the method, the coil of the magnetic field emitting antenna and a ground induction coil of an original parking lot management system are shared, the coil of the magnetic field emitting antenna is connected with the commutation circuit; time-sharing work is realized under the action of the commutation circuit, and non-interference is realized.
Description
Technical field
The present invention relates to managing system of car parking field, refer more particularly to a kind of for emission of magnetic field antenna and the shared method of parking system ground induction coil.
Background technology
At present, rfid system is at parking lot management closely on induction system, increase that a RFID read head (induction) forms, as bluetooth read head, infrared read head and microwave read head etc., above-mentioned these read heads more or less all come with some shortcomings, as communication distance is difficult to control, be easily subject to extraneous factor impact and service condition restricted etc., the system usability of causing is stable not.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point of the prior art and provide a kind of simple in structure, stable performance, cost is low, is applicable to the shared method of emission of magnetic field antenna and parking system ground induction coil.
The present invention realizes in the following way:
For emission of magnetic field antenna and the shared method of parking system ground induction coil, it is characterized in that: comprise emission of magnetic field antenna 1, commutation circuit 2, remote sensing key, remote sensing controller, described emission of magnetic field antenna 1 is connected with commutation circuit 2, during normality, the coil of emission of magnetic field antenna 1 is parking system ground induction coil, when parking system ground induction coil has sensed metallic foreign body, parking system ground induction coil sends induced signal to remote sensing controller, remote sensing controller drives commutation circuit 2 the shared coil in parking system ground induction coil state to be switched to the coil of emission of magnetic field antenna 1, now emission of magnetic field antenna 1 sends field signal, described field signal wakes remote sensing key up, remote sensing key transmitting radio frequency encoding signal is to remote sensing controller, remote sensing controller carries out carrying out corresponding action after analyzing and processing to radio frequency coded signal.
Beneficial effect of the present invention is: the coil of emission of magnetic field antenna and the ground induction coil of managing system of car parking, and the two shares, and under the effect of commutation circuit, realizes time-sharing work, does not interfere with each other, and has not only met function but also provided cost savings; Coil due to emission of magnetic field antenna can share with the ground induction coil of managing system of car parking in addition, therefore can the installation site of the coil of emission of magnetic field antenna is embedded in underground.
