System and method for improving accuracy rate of monitoring residual parking spaces

The invention discloses a system and method for improving the accuracy rate of monitoring remaining parking spaces. The system comprises an anti-smashing sensing module, a single-face sensing module and a control center. The anti-smashing sensing modules are arranged at vertical positions of an entrance and an exit of the parking lot, are used for sensing an on-off signal X1 when a vehicle enters the parking lot and an on-off signal X2 when the vehicle leaves the parking lot, and are used for transmitting a detection signal to the control center; the single-face sensing modules are arranged at the transverse positions of an entrance and an exit of the parking lot and serve as sensing signals Y1 when a vehicle enters the parking lot and sensing signals Y2 when the vehicle leaves the parking lot, and detection signals are transmitted to the control center. And the control center compares the received on-off signal X1 with the sensing signal Y1, or compares the on-off signal X2 with the sensing signal Y2, thereb
