Intelligent parking space reservation interactive system and use method

The invention relates to an intelligent parking space reservation system. The intelligent parking space reservation system comprises a parking entrance and exit detection recognition reminding device, a handheld mobile intelligent application terminal, a parking lot management center, a network service center, a parking detection sensing module and an identity card. A pressure sensor is adopted by the parking detection sensing module, detects a parking signal, and transmits the parking signal to the parking lot management center; the parking lot management center receives the signal of the sensor, judges the remaining parking spaces in a parking lot, transmits information of the remaining parking spaces to the network service center and the parking entrance and exit detection recognition reminding device, and reminds a vehicle entering the parking lot of the information; the parking entrance and exit detection recognition reminding device sends the positions of the unoccupied parking spaces in a current state in a plane map mode through the network service center to the verified mobile intelligent terminal of a driver after identity recognition is conducted on the mobile intelligent terminal and the identity card held by the driver. By the adoption of the intelligent parking space reservation system, the driver can reserve the parking space through the intelligent parking space reservation system before going out, and the phenomenon that the driver spends plenty of time and energy finding the parking space is avoided.
