Vehicle detector  principle :vehicle detector is the use of LC oscillator to detect whether there are metal objects at the coil to achieve the detection of the vehicle. Vehicle detector has a fixed capacitance, and then in the ground around a 3-5 m long coil, when the coil is not the vehicle when the inductance is relatively low, LC oscillation frequency is relatively high, the frequency is greater than 50Hz, when the coil has Vehicle, the inductance increased sharply, the frequency of lower-end LC oscillation, this time the frequency is less than 50Hz. Vehicle detector can be based on the frequency of LC oscillation to determine whether there is a vehicle through. In this case, Vehicle detectors are commonly used in parking lot systems. A, Vehicle detectors are used in conjunction with the barrier, and the B vehicle detector is used in conjunction with an automatic card reader. In this case, When the vehicle detector and the barrier with the use of vehicles at this time detec...
