[0003] In the prior art, with the increasingly refined operation of parking lots, the operation mode is increasingly rich, and the differentiation is increasingly large, so that different parking spaces in the same physical parking lot may belong to different operating subjects, and there are cases of parking space sales and parking space contracting, and the parking space resources in the parking lot may not all belong to the same operating subject. For example, in a large parking lot, a part of parking spaces belong to A company, a part of parking spaces belong to B company, and a part of parking spaces belong to an individual. When the parking lot provides services to the outside, if the conventional parking lot operation is adopted, it is impossible to differentiate and settle according to the parking space belonging to the operating right, and more and more parking lots start to operate in a nested parking mode, and different regions of a parking lot have multiple charging standards. Such a complex charging mode leads to inconsistent charging and many problems. SUMMARY
