The vehicle-machine binding time coefficient is obtained by calculating the absolute value of the scanning time of the mobile terminal smart device, and the vehicle-machine binding time coefficient is matched with the preset vehicle-machine binding time interval. If the vehicle-machine binding time coefficient belongs to the preset vehicle-machine binding time interval, the mobile terminal smart device of the vehicle driver or other passengers in the vehicle is successfully bound to the current vehicle; otherwise, the mobile terminal smart device of the vehicle driver or other passengers in the vehicle fails to be bound to the current vehicle, and the vehicle license plate number, vehicle brand and body size can be manually entered on the boot platform program for binding; if there is no binding between the vehicle and the mobile terminal smart device, the existing technology is used (only the vehicle license plate number is scanned for identification and marking to enter and exit the parking lot); Step 2: By matching the current vehicle's body size with the parking space type, if the parking space type of the current vehicle's body size is an ordinary parking space, obtain the empty ordinary parking spaces in the parking lot; if there are multiple empty ordinary parking spaces, obtain the parking spaces with a high-quality comprehensive status of easy parking and environmental monitoring among the empty ordinary parking spaces; if there is no parking space with a high-quality comprehensive status of easy parking and environmental monitoring among the empty ordinary parking spaces, obtain the parking spaces with a high-quality comprehensive status of general parking and environmental monitoring, and so on, and obtain the corresponding parking space location information, and mark the corresponding parking space as an occupied parking space; then connect the mobile terminal smart device to the Bluetooth or Wi-F in the parking lot through the boot platform program, and then obtain the vehicle's location information through the Bluetooth and Wi-F positioning system; and substitute the corresponding parking space location information and the corresponding vehicle location information into the preset parking lot location coordinate map. The corresponding parking space position coordinate point and the corresponding vehicle position coordinate point are obtained in the preset parking lot position coordinate map, and then the path data in the preset parking lot position coordinate map is obtained to generate a parking navigation path, and the generated parking navigation path is displayed on the mobile terminal smart device; if the corresponding vehicle driver does not park according to the parking navigation path, but chooses other ordinary parking spaces, the parking space status corresponding to the parking navigation path is detected according to the parking space analysis module, and if the parking space status of the corresponding vehicle is detected to be an empty parking space, the corresponding parking space is marked as an empty parking space again; then the corresponding vehicle position coordinate point is obtained and matched with the position coordinate point interval of the corresponding vehicle parking space, if the corresponding vehicle position coordinate point belongs to the position coordinate point interval of the corresponding vehicle parking space, the position coordinate point of the corresponding vehicle parking space is used as the parking space of the current vehicle, and the position is marked as the parking space position information; Step 3: When the driver or passenger of the corresponding vehicle returns to the parking lot to pick up the vehicle, the guidance platform program can be opened in the mobile terminal smart device, and the location information of the driver or passenger can be obtained through the Bluetooth and Wi-Fi positioning systems. The location information of the corresponding driver or passenger and the parking space location information of the corresponding vehicle are substituted into the preset parking lot location coordinate map to obtain the location coordinate point of the corresponding driver or passenger and the parking space location coordinate point of the corresponding vehicle, and then the path data in the preset parking lot location coordinate map is obtained to generate a vehicle pickup navigation path, and displayed on the mobile terminal smart device; the parking space analysis module then detects the parking space status corresponding to the parking space location coordinate point of the vehicle. If the parking space status of the corresponding vehicle is detected to be an empty parking space, the environment analysis module analyzes the traffic flow data to obtain the traffic flow status, and selects the exit with a traffic flow status of unobstructed traffic flow, generates an exit navigation path, and displays it on the mobile terminal smart device; if all exits of the parking lot do not have a traffic flow status of unobstructed traffic flow, select the exit with a traffic flow status of light traffic congestion, and so on; Step 4: Calculate the parking fee amount by obtaining the parking time of the vehicle, the parking space type and the parking lot's charging standards, and make the payment within the guidance platform program; if the vehicle is bundled with the mobile terminal smart device or not, make the payment through the existing technology (scan the charging program to pay).

When the vehicle driver or other passengers in the car use a mobile terminal smart device to scan it, the mobile terminal smart device of the vehicle driver or other passengers in the car is bound to the current vehicle; Match the current vehicle's body size with the parking space type, generate a parking navigation path by acquiring path data in a preset parking lot location coordinate map, and display the generated parking navigation path on a mobile terminal smart device; If the driver of the corresponding vehicle does not park according to the parking navigation path, but chooses other ordinary parking spaces, the parking space analysis module detects the status of the parking space corresponding to the parking navigation path. If it is detected that the parking space status of the corresponding vehicle is an empty space, the corresponding parking space is marked as an empty space again; Then, the corresponding vehicle position coordinate point is obtained and matched with the position coordinate point interval of the corresponding vehicle parking space. If the corresponding vehicle position coordinate point belongs to the position coordinate point interval of the corresponding vehicle parking space, the position coordinate point of the corresponding vehicle parking space is used as the parking space of the current vehicle, and the position is marked as the parking space position information; When the driver or passenger of the corresponding vehicle returns to the parking lot to pick up the vehicle, the location information of the driver or passenger is obtained, and the location information of the driver or passenger and the parking space location information of the corresponding vehicle are substituted into the preset parking lot location coordinate map to generate a navigation path for picking up the vehicle, which is displayed on the mobile terminal smart device; The parking space analysis module detects the parking space status corresponding to the parking space position coordinate point of the vehicle. If the parking space status of the corresponding vehicle is detected to be an empty parking space, the environment analysis module analyzes the traffic flow data to obtain the traffic flow status, selects the exit with a traffic flow status of unobstructed traffic flow, generates an exit navigation path, and displays it on the mobile terminal smart device; if all the exits of the parking lot do not have a traffic flow status of unobstructed traffic flow, select an exit with a traffic flow status of lightly congested traffic flow, and so on; Obtain the parking time of the vehicle, the parking space type and the parking lot's charging standards to calculate the parking fee amount, and make payment within the guidance platform program.
