And the cloud control platform is used for comparing the characteristic vector constant with the position coordinates of the traffic marking and the traffic sign board on the traffic road surface in real time, and issuing traffic violation early warning and real-time punishment information in real time according to the comparison result. Wherein, the characteristic vector constants are explained as follows:

because the installation position of the satellite positioning antenna/laser positioning pulse sensor of the vehicle-mounted terminal on the vehicle is fixed (the satellite positioning antenna/laser positioning pulse sensor is uniformly installed at a specific position of the vehicle by a traffic or vehicle management department), the coordinate parameters from the satellite positioning antenna to the ground vertical point and the distance relationship between the coordinate parameters of four tires at the front, the rear, the left and the right of the vehicle and the ground tangent point have uniqueness, and the five groups of coordinate data with fixed correlation are associated with the electronic number plate of the vehicle to define a characteristic vector constant; because the wheel track and the wheel base of vehicles of different brands, different vehicle types and different styles are respectively fixed and unchangeable, the real-time state of the vehicle is reflected by the real-time comparison result of the characteristic vector constant of the vehicle, the traffic marking coordinate parameter of the position of the vehicle and the coordinate parameter of the position of the traffic signboard, and whether the vehicle meets the regulations of traffic regulations (the operations of running, turning around, giving way, parking and the like of the vehicle) is obtained in real time; vehicles of the same make, model, have the same common "feature vector constant"; vehicles of different brands and models have different "feature vector constants", the same below. Binding the 'characteristic vector constant' of each vehicle with the electronic number plate of the vehicle, solidifying and writing the 'characteristic vector constant' into the 'vehicle-mounted terminal' of the vehicle (the 'characteristic vector constant' is finished by a traffic management department) as legal electronic identification of the vehicle; the coordinate parameter set of the ground projection boundary of the vehicle shell is axially symmetrically superposed with the characteristic vector constant of the vehicle, the vehicle projection and the high-precision electronic map of the system are dynamically bound in real time by utilizing three-dimensional animation and video processing technology, and the three-dimensional animation video can be directly used as a reference for intuitive operation and accurate parking when the vehicle runs and parks in a position, so that the visual effect of ' bird's-eye view ' is achieved.

Based on the above description of the relevant modules of the system, the working principle and the specific application scenario of the system are described in detail:

the working principle of the system is as follows: adopting a real-name driving scheme of a motor vehicle, and binding a face recognition technology (face sweeping), a motor vehicle electronic license plate technology (including original factory data such as traction force, engine power, wheel spacing, front and rear axle spacing, empty vehicle dead weight and the like), a vehicle 'characteristic vector constant' (defined in the following text) and a personal account; namely: the vehicle driver personal information is associated with personal account information, vehicle technical parameters, vehicle "feature vector constants" information. And requiring a certain amount of deposit balance to be prestored in the personal account of the driver as a precondition for vehicle ignition starting and real-time punishment acceptance of the driver in traffic violation.

The application scenarios of the system comprise:

1. supervision of driving without license, fatigue, "top-bag driving"

Before starting a vehicle each time, the vehicle-mounted terminal automatically performs a routine 'face scanning recognition' driver driving qualification verification program, compares the face information of 'face scanning recognition' with the personal information of the driver prestored in the cloud control platform database of the system, and simultaneously checks whether the satellite positioning antenna/laser pulse sensor is shielded? Comparing the balance of the driver's personal account with the balance of the driver's personal account to ensure that the driver can perform subsequent motor vehicle operation, otherwise, the vehicle cannot be ignited and started; the system sets a driving period from ignition starting of the vehicle to leaving the seat or flameout stopping of the driver; according to the traffic regulations, each driving period is less than or equal to 4 hours; the information of each time of face scanning recognition is synchronously recorded on the cloud control platform of the system, and is used as a basis for monitoring and judging whether a driver is in fatigue driving in the driving period and as a reference basis for vehicle insurance claim settlement and responsibility confirmation; after the vehicle is started and starts to normally run, the system starts a 'face sweeping recognition' program according to a set interval in each driving cycle, compares and verifies the driving identity of the driver in a rolling record mode, automatically updates 'face sweeping recognition' information in the previous period, ensures the integrity and uniqueness of the personal record of the driver in each driving cycle, and takes the record as the basis for punishing the driver in real time when traffic violation occurs in the driving cycle; when the personal account balance is insufficient due to real-time punishment on traffic violation of a vehicle driver in the driving process, the vehicle-mounted terminal closes the vehicle ignition system and prompts the information of the personal account balance insufficiency when the vehicle-mounted terminal is ignited and started in the next driving cycle, and the vehicle-mounted terminal can restart the normal ignition program until the account balance meets the basic requirement. The above functions of the system can supervise and prevent driving without a license, fatigue driving and top-bag driving in real time (refer to fig. 2).

And the reserved parking spaces which are withdrawn halfway are returned to the vacant parking space database of the parking lot immediately. Any vehicle is allowed to reserve only one parking space at the same time; once the remote parking space is reserved, the information is locked by the cloud control platform database of the system, and other vehicles cannot be repeatedly applied and reserved;

the function is suitable for the vehicle seeking the parking space; vehicles already parked in a legal parking space are not allowed to reserve a second parking space at the same time, so that parking space resources are prevented from being repeatedly occupied.
