As shown in fig. 2, one geomagnetic device 4 is provided for each parking space in the parking lot. The geomagnetic device 4 has an NB-IoT function. The geomagnetic sensor can monitor the state of the parking space in real time, and report the monitored state of the parking space to the central cloud server through the NB-IoT function according to the second time period, so that the state of the parking space is reported to the central cloud server in real time, and the central cloud server updates the current state of the parking space in the parking lot database according to the received state of the parking space.
Step 205, the central cloud server inquires whether an idle parking space exists according to the current state, and if so, step 207 is executed; if not, go to step 206.
In the embodiment of the invention, the central cloud server inquires whether the current state comprises an idle parking space or not according to the current state, and if so, the central cloud server indicates that the idle parking space exists; continuing to execute step 207; if not, indicating that no free parking space exists, and continuing to execute the step 206.
Step 206, the central cloud server sends a waiting message to the mobile terminal, and continues to execute step 201.
In the embodiment of the invention, as no free parking space is available for the vehicle to be parked to park in the parking lot, the central cloud server is required to send the waiting message to the mobile terminal. As an alternative, the waiting message is "no free space currently, please wait. ".
In the embodiment of the invention, after receiving the waiting message sent by the central cloud server, the mobile terminal displays the waiting message to remind the user of waiting for the parking space, and the user can continue to wait, and step 201 is executed, and the mobile terminal sends parking request information to the central cloud server until a matched parking space exists.
And step 207, generating parking point position information by the central cloud server.
In the embodiment of the present invention, as shown in fig. 2, each parking space includes a parking spot, such as the parking spot A, B, C, D, E or F, which is disposed on the aisle while being adjacent to the parking space.

Three possible embodiments are illustrated here: in the first mode, the central cloud server randomly screens out one free parking space from all the free parking spaces, and determines the free parking space as a target parking space; in the second mode, the central cloud server screens parking spaces with parking space sizes larger than or equal to the size of the vehicle from all the idle parking spaces, and determines the screened parking spaces as target parking spaces. If a plurality of screened parking spaces exist, the parking space corresponding to the smallest parking space size can be determined as a target parking space; in the third mode, the central cloud server screens out an idle parking space closest to the current position of the vehicle from all the idle parking spaces, and determines the idle parking space as a target parking space. The above three ways are only examples and are not limited to the above three ways.
It should be noted that the parking spot position information may also be generated by other manners, and the embodiment of the present invention is only exemplary and is not limited thereto.
And step 208, the central cloud server sends the parking point position information to the mobile terminal.
In the embodiment of the invention, the central cloud server sends the number of the target parking space in the parking space position information to the mobile terminal, so that the mobile terminal can display the number of the target parking space, and a user is informed of the parking space number of the target parking space to be parked.
And step 209, the central cloud server receives a reservation instruction input by the user through the mobile terminal.
In the embodiment of the invention, the mobile terminal displays the number of the target parking space and simultaneously inquires whether the user reserves or not, and the user can click a reservation button or a non-reservation button through the mobile terminal. And if the user clicks the 'no reservation' button, the user is indicated to give up the autonomous parking.
Step 210, the central cloud server responds to the reservation instruction, and the parking space state information is updated.
