VEHICLE SENSOR, DETECTING METHOD THEREOF AND SELF ENFORCING PAY-BY-PHONE PARKING SYSTEM USING THE SAME

摘要

A vehicle presence detecting sensor (10) associated with a defined area, wherein, the sensor (10) comprises a microprocessor (100), and a first detecting module (11), a second detecting module (12), as well as a third module (13), respectively connected to and controlled by the microprocessor (100), wherein, the microprocessor (100) is configured for activating the second detecting module (12) when a change of magnetic field is detected by the first detecting module (11) or activating the third module (13) when the distance measured falls out of the pre-determined distance range, and for confirming the presence of a vehicle by comparing the distance measured by the second detecting module (12) with a predetermined distance range, or by matching the value of the detailed change of magnetic field detected by the third module (13), with pre-stored values. Also, a method of the sensor (10) and a self enforcing pay-by-phone parking system using the sensor (10) are disclosed.
