Description

Data processing method of parking lot system

Technical Field

The invention relates to the field of electric signal data processing, in particular to a data processing method of a parking lot system.

Background

In recent years, with the progress of technology and the development of economy and the pursuit of the public for higher living standards, vehicles enter ordinary households and are gradually becoming necessities of life. Meanwhile, with the rapid and deep development of the internet plus and the close connection with various industries, the modern society enters a highly information era. The rapid and large increase in the holding capacity of vehicles presents several challenges. For example, in the case of parking vehicles, temporary or short-term parking of vehicles has often required human intervention over the past long period of time. Early on, people were required to perform the checking and scheduling of storage space, to inform accordingly whether there was space for a vehicle to park, and to determine whether to clear, and to record time and charge fees. After that, it is greatly improved due to the introduction of the information system. The storage space and the available quantity are obtained through the central control platform, and scheduling is carried out intelligently, but the terminal still needs people to identify, schedule, release and charge. The prior art has some problems, along with the establishment of a business area, a central control platform can be shared among the whole area or a plurality of business buildings and buildings, meanwhile, information and resource sharing can be carried out among the parking resources, and due to the fact that a plurality of entrances and exits are arranged, some asynchronization can occur among data capture, processing, coordination and scheduling of all entrances and exits, and therefore information among all the entrances and exits can affect data copying, updating, optimizing, scheduling and the like of the central control platform. And if the clock and data of the entrance and exit cannot be synchronized with other nodes, the available parking space is inaccurate in the peak period, so that the vehicle is jammed at the entrance or the space is searched in the parking lot, the time of a user is wasted, the additional consumption of energy used by the vehicle is caused, and the efficiency of passing the vehicle in and out is reduced.

There are some solutions that seek improvement among the prior art, for example, patent application No. CN201610894660.2, which solves the problems of low efficiency, low accuracy and poor user experience of parking lot parking space information processing solutions. However, the data synchronization unit is used for sending the updated information of the number of remaining parks to the terminal, and the specific means for realizing the information is not shown, and the problem of clock synchronization between each point and the parking space information processing server of the parking lot cannot be emphasized. For another example, patent application No. CN2016105020231, which provides a prepaid-based intelligent parking lot operation method, the parking lot management system can directly communicate with the local server, and the stability and speed of communication can be improved. But it does not highlight how to synchronize, nor does it address the problem caused by clock asynchronism. In addition, the prior arts cannot consider how to make other parts of the parking lot system operate normally in case of a failure of the entrance and exit device; in addition, because the power supply module is unstable to a certain degree, the clock synchronization is often affected; and the supply of the clock needs to be stable and uncontrolled.

In view of the above, there is a need for a data processing method for a parking lot system, which can maintain the data transmission and quick update between each entrance and exit and a central control platform, can also achieve clock synchronization, and can improve the passing efficiency of the entrance of the parking lot, and can enable other parts of the parking lot system to normally operate when the entrance and exit device fails, and avoid the influence of the instability of a power supply module on clock synchronization, and provide a stable and uncontrolled clock signal, and further solve a series of problems caused by the above.
