Overview
As a component of transportation facilities, parking lots have become more and more busy and continuously developed, and people’s management requirements have also been continuously improved. They all hope that management can achieve convenient, fast and safe effects; however, the scale of parking lots varies. There are also differences in the mode of management. Managers can choose to apply economical and stable management procedures according to their own conditions, instead of choosing a high-cost management system because of the lack of information needed for the time being. The following will describe a basic scheme for implementing management requirements with a handheld.
Work management process
The system can be divided into two components:
1. Management part;
2. Handheld part.
The management part is mainly completed:
1. IC card management. Users have different choices for the use of parking lots. Therefore, the types of IC cards are different. There are general, monthly, and stored-value IC cards, so the IC card management process It is necessary to initialize the IC card that has been produced, write the corresponding information, assign a password to the IC card, and write each record of the card issuance into the database to provide data for future statistics, query and other related tasks. At this time, IC card is officially put into management operation;
2. Data management. Since the card types are monthly rent and stored value, they must contain user information. To protect the interests of users and facilitate their own management, management of this part will be necessary;
3. System management, the scope of functions of this part can actually be many, but basically, it needs to provide the program code and data (settlement rate, etc.) that the handset runs, as well as receive the vehicle in and out time, amount, etc. from the handset Data and save the data in the database to provide a basis for statistics, inquiries, and reports;
4. Statement analysis, providing financial statements for financial management, as well as other types of statistical statements. In fact, the management part can continue to extend outside based on the above functions to realize the management requirements of the parking lot. Handheld part. A handheld computer is actually a computer device that can be solely responsible for part of the work, so it can reduce the laying of the network. The work process is as follows:
1. When the vehicle enters the parking lot, the staff will issue an IC card to the driver. If the driver already has a monthly rental card or a stored-value card, the staff will put the card in the handheld like other cards To operate, the handset writes the current system time (automatic) and license plate number (input by the staff) into the card, and the driver enters the parking lot with the card;
2. When the vehicle leaves the parking lot, the driver gives the card to the staff, the staff puts the card in the handset for operation, and the handset judges the card type and makes corresponding processing. According to the current system time, the vehicle’s status is obtained. Stay time, and get the settlement amount from the settlement rate stored in the handheld device. If the IC card is a general form of IC card, the driver will pay the amount, and the staff will release the IC card after it is collected; if the IC card is a stored value Card, the handset will deduct the fee from the IC card. After the completion, the driver will leave with the card.
Every time such an operation is completed, the handheld will save the operation record, and the staff will upload the recorded data regularly, which will be processed by the management program. The following process diagram is now drawn:
For the settlement rate, the management program will provide a modification window for adjusting the rate, and the adjustment result will be stored in the database. Therefore, the handset can obtain the latest settlement rate at any time without modifying the program.

System block diagram
According to the above description, the block diagram of the system function can be organized as follows:
System network
Since the handset is a device that can work alone, it can reduce laying in terms of network construction. Like a general local area network, a local area network should also be set up inside the parking lot to fully guarantee the normal operation of the management system. At the same time, the constructed network is still easy to expand and transplant, and adapt to the needs of future system development. The basic network topology is as follows:
For equipment introduction, see the product description section:
Business operation method:
1. First, the road parking management company must force the parked vehicles to use a card to consume parking.
2. Road inspectors and supervisors cannot collect cash.
3. The card value is divided into several grades, such as 10, 20, 50, 100, 200. It is sold on the market by cash card.
4. The government must issue documents to cooperate with the operation of the project and gain the understanding of the majority of drivers.
