The five basic structure of intelligent parking lot system small make up to introduce the main content of this paper is, intelligent parking lot system is based on modern electronics and information technology, at the entrance of parking area of the installation of automatic identification equipment, through the non-contact or license plate recognition to access this area of the implementation of judgment recognition, access/deny, guiding, record, collect fees, customs and other intelligent management, its purpose is to have control of vehicles and personnel in and out.

Record all the detailed information and automatically calculate the charging amount to realize the safety management of the internal vehicle and the charge. It is divided into two modules: car park management system and parking fee system. The parking of urban vehicles is one of the important factors affecting the transportation links between urban and urban areas. Basic composition system and the intelligent parking equipment: parking display system, management software system, security system, monitoring system, computer image contrast, exports controller, ground sense coil, automatic brake and vehicle sensors, communication adapter, transmission equipment, etc. Here are the basic functions:

The five basic structures of intelligent parking systems.

1. Parking display system: the parking display system is composed of the parking detector, the parking space display, the display light of the vehicle field, the parking indicator light and the signal processor. A detector is set in each lot, through the signal processor into management software subsystem, car display screen will display the current driver for the best parking space, parking lights open and bright, guide the driver to stop. If there is no parking space in the garage, the display screen shows no vacant parking Spaces, and no more vehicles are accepted into the garage.

2. Management software system: record parking time, charge calculation, parking space, vehicle image information, parking space turnover rate, average access time and other data and provide various data reports.

Anti-theft system: a set of high code bit remote control and parking detector parallel work to the parking space, and the parking detector has the function of watching the car. When the driver enters the garage to stop, operate the remote control to the vehicle code; When the driver is ready to withdraw from the warehouse, the remote control is used to decode the vehicle. If there is no decoding car, the alarm system works and the monitoring system can be used to prevent the vehicle from being stolen.

3. Monitoring system: the monitoring system consists of camera, controller, monitor and video recorder. Under the control of the controller, the camera is continuously filmed and sent to the monitor to monitor the operation of the lane. At the same time, the video recorder is working to record the running information of the vehicle. When there is a traffic jam in the driveway, the police will quickly call the police and organize the rescue to ensure the smooth lane. In addition, the camera also monitors the parking garage to ensure the safety of parking. Control the indoor camera to monitor the operator to prevent the operator from stealing money.

4. Computer image comparison system: computer image contrast system is composed of camera, snapshot controller and image processor. When vehicles cross into library card or collect the tickets, capture control system work under taken images of the license plate number, by main control computer, together with card or ticket information held by the driver in the system database. When the vehicle is out of the library inspection card or check ticket, the snapshot control system works again with the image of the license plate number and compares it with the information in the system database. If the information is consistent, the same vehicle shall be given the release; Otherwise, no release and automatic alarm.

5. Export control system: when outbound vehicles, vehicle detector induction outbound signal and inform the master control computer operators to operate, the check-in machine automatic display driver in card or pay the ticket. If it is a fixed user, the driver will exit the card and swipe the card to check the ticket. After the billing is correct, the gate will be opened and the vehicle will be released. If it is a temporary user, the driver will pay the ticket by the operator, and then the gate will open and the vehicle will be released. After the vehicle is out of the warehouse, the gate is automatically returned.
