Working principle of the present invention:

In this embodiment, the car battery or car battery supplies power to the second single-chip microcomputer 11, the drive circuit 13 and the Bluetooth transmitter module 15, and the Bluetooth transmitter module 15 regularly transmits the license plate information under the control of the second single-chip microcomputer 11, and the Bluetooth of the ground lock terminal 2 Receiving module 22 sends data into first single-chip microcomputer 21 after receiving the license plate information that bluetooth transmitting module 15 sends, and first single-chip microcomputer 21 compares this information with the license plate information of this ground lock car owner that has been stored in it in advance, if The information is consistent, indicating that it is the car of the owner of the parking space, then the first single-chip microcomputer 21 sends a signal to put down the ground lock body 29, such as sending a signal "1" to the motor drive circuit 27, and the motor drive circuit 27 drives the motor 28 to rotate forward, and the motor 28 drives The movement of screw rod 2912 and slide block 2913 allows the ground lock body 29 to be put down, and the car of the owner can be parked in the parking space. Otherwise, the first single-chip microcomputer 21 does not send a signal to the motor drive circuit 27, the motor 28 does not move, the ground lock body 29 does not put down, and the car of the non-parking space owner cannot be parked in the parking space. Ultrasonic sensor 210 regularly detects whether there is a car on the parking space, and when detecting that there is a car, then sends a "car" message to the first microcontroller 21; when the car leaves the parking space, ultrasonic sensor 210 detects that there is no car, then sends "no car" Information to the first microcontroller 21. In this embodiment, the ultrasonic sensor 210 is made up of an ultrasonic transmitting end and an ultrasonic receiving end. When there is a car, the ultrasonic wave at the ultrasonic transmitting end encounters an obstacle and is reflected, and the ultrasonic receiving end receives the ultrasonic wave; when there is no car, the ultrasonic wave at the ultrasonic transmitting end If the ultrasound is not reflected, the ultrasound receiving end cannot receive the ultrasound, so it can be judged whether there is a car in the parking space. The first single-chip microcomputer 21 receives the "no car" signal, and then sends a pop-up lock signal to the motor drive circuit 27, such as sending a signal "0", the motor drive circuit 27 drives the motor 28 to reverse, and drives the screw rod 2912 and the slider 2913 to reverse. Direction movement allows ground lock body 29 to rise. When the first single-chip microcomputer 21 receives the “vehicle has” signal, the first single-chip microcomputer 21 does not send a signal to the motor drive circuit 27 . When the ultrasonic sensor 210 detects that there is a car, the first single-chip microcomputer 21 controls the bluetooth module to stop receiving bluetooth information (there are two ways to stop receiving bluetooth information, one is to control the first power supply module to stop supplying power to the bluetooth receiving module 22, the second The second is that the information received by the bluetooth receiving module 22 is not processed in the first single-chip 21 program), which can save power, and can not be sent to the drive circuit when the first single-chip 21 cannot read the information received by the bluetooth receiving module 22 simultaneously. The signal of "1" means that the motor 28 will not be repeatedly driven to rotate forward. Of course, the motor 28 will stop running after it forwards to the first limit block. Even if the first single-chip microcomputer 21 sends a "1" signal command motor 28 will not continue. Forward rotation, double insurance, prevents the motor 28 from being stuck and damaged due to the motor 28 running all the time. Simply put, only when the first single-chip microcomputer 21 reads that the license plate information received by the Bluetooth receiving module 22 is correct, the first single-chip microcomputer 21 sends "1" to the motor drive circuit 27, the motor 28 rotates forward, and the ground lock body 29 is put down; 28 forward limit control, slide block 2913 runs into first limit switch 2915, and motor 28 stops rotating. When the ultrasonic sensor 210 detects that there is no car, the first single-chip microcomputer 21 sends a "0" signal to the motor drive circuit 27 to control the reverse rotation of the motor 28 and bounce the ground lock body 29, and the reverse rotation of the motor 28 is also provided with a limit block, that is, a slider 2913 runs into the second limit switch 2911, and the motor 28 stops rotating. When the ultrasonic sensor 210 detects that there is no car, the first single-chip microcomputer 21 starts the charging power supply 25 to supply power to the bluetooth receiving module 22 or starts the bluetooth receiving module 22 in the program to receive and process the license plate information function that bluetooth sends, and the bluetooth receiving module 22 enters to receive bluetooth information status.
