I. Introduction
With the acceleration of China's modernization process, the traffic volume of various parking lots is increasing day by day, and its daily security and management work is becoming increasingly heavy. In order to better cooperate with the security and management of each parking lot, this paper specifically introduces this set of intelligent management and control system for parking lots.
The parking lot charge management system utilizes highly automated electromechanical and microcomputer equipment to safely and effectively manage the parking lot, including charging, security, surveillance, and theft prevention. This system is specially designed for the automatic identification and billing of motor vehicles in high-end commercial and residential buildings, high-grade office buildings and high-end apartments and hotels. It is a good combination of reading recognition technology, large-scale integration technology and computer technology. A new security management system. It uses the reading technology to automatically identify the driver of the card, and provides automatic means and commercial supervision for the security and billing management of the parking lot through the cooperation of the barrier and the special software technology. The system technology, simple operation, high reliability and confidentiality, is a modern vehicle intelligent management control system.
Depending on the object of use, parking lots can be divided into two categories: internal parking and public parking.
The internal parking lot is mainly for fixed car owners, and is generally used for self-use parking lots of various units, parking lots for apartments and residential quarters, underground garages for office buildings and office buildings. This type of parking lot is characterized by the user's fixed, prohibiting the use of external vehicles. The user has a long time to use the facilities, and the safety requirements for the management of the yard are strict. The density of access is high during the peak hours of commuting, and the parking equipment is reliable. Sex and processing speed requirements are high.
Public parking is mainly for temporary FITs, with fees and free points. Such parking lots are common in large public places such as stations, airports, stadiums and the like. The users of the yard facilities are usually temporary one-time users, with a large number and short time. The yard management system is required to have low operating cost, simple use, and firm and reliable equipment, which can meet the commercial processing requirements such as charging. In view of the above characteristics, the parking lot management system is designed for an integrated parking lot with both internal vehicles and temporary toll vehicles. The design of the system has a modular function, so that for specific projects, the scheme can be selected according to the building. The grades, the number of vehicles, the number of garage entrances and exits, the nature of the garage, the ratio of fixed vehicles to temporary vehicles, and the amount of expenses, etc., take into account the increase and decrease of each subsystem, flexible and convenient.
Second, the characteristics of the management system

- Sound and light alarm.
Third, the main functions of the system
1. The system divides users into two types, one is a fixed user and the other is a temporary user. Fixed users pay in advance (one month, three months, six months or one year) and no longer charge each time they play. Temporary users will pay once according to the current parking time and current rate when they appear.
2. All vehicles are accessed by card, and the time, location and vehicle information of the card are automatically displayed and recorded on the computer.
3. After all the vehicles have swiped the card, they will be charged by the toll collector (temporary user) or confirmed (fixed user).
4. The travel time and alarm time can be set arbitrarily, and the programming can be set regularly in case of special circumstances.
5. The system has a hierarchical management function, and personnel have recorded the system.
6. Card management functions are detailed.
7. The above functions are automatically recorded by the computer, and the access report, card report and alarm report can be printed.
8. The ground coil technology used in this system controls the falling of the arm. A ground-sensing coil is installed at the arm of the electric vehicle arm. When the vehicle enters the card reading range, the driver reads the card, and the system determines whether it is invalid or invalid. When the vehicle is in effect, the electric arm is lifted, and when the vehicle enters the sensing range of the ground-sensing coil, the ground is The sense coil self-determines whether the vehicle has traveled (within the effective range). If the vehicle fails to pass, the electric arm does not fall. After the vehicle passes (within the effective range), the electric arm is lowered to complete the task. If the vehicle trails into the vehicle, the signal is output from the ground coil so that the electric arm does not fall. Only when the vehicle passes through the entrance and exit and travels a predetermined safe distance, the bar will fall, thus ensuring the safe passage of the vehicle.
Fourth, the composition of the system
The parking lot charge management system includes two parts: the management center equipment and multiple sets of workstation charge management equipment.
Management center equipment: including management computer, management software, and IC card issuing equipment.
