First, system overview
As an important part of the intelligent community, the vehicle access management system uses advanced technology and highly automated equipment to safely and effectively manage vehicle access and parking. Intelligent parking is to integrate the residential area parking lot computer management center into the house intelligent management system, adopt advanced IC card technology and automatic control technology, make the system highly automated, and minimize losses caused by personnel costs and human errors. Greatly improve the safety and efficiency of the entire parking lot. The system software has perfect financial monitoring and statistical reports, effectively blocking the loss of funds and financial loopholes. The vehicle access management system is a management system for accessing and parking vehicles in the community. Therefore, installing a vehicle access management system at the vehicle entrances and exits in the community can ensure the safety of vehicles in the community and facilitate the understanding of the dynamic situation of vehicles in and out of the community. Accurate, efficient and dynamic management. Fixed users in the community can use a single type of card, access the community, and park vehicles.
Second, system design principles and basis
As a typical computer network application system, the vehicle access management system should follow the principles of practicability, safety, advanced, economical, reliable, and expandable, and on the basis of ensuring the effective, stable and reliable performance of the system, consider the advanced nature of the system. In order to meet the requirements of the level of community security precautions, try to reduce the system cost, in order to achieve the best performance-cost ratio. Taking into account the actual needs of users and the development trend of information technology, based on the user's on-site environment, the design and selection of functions and system configuration solutions that meet the user's requirements are adopted. Through a rigorous and organic combination, real resource sharing and one-card service are realized.
Third, the program design
(a) specific plan
The vehicle access management system consists of a non-contact ID card parking lot master controller, a parking lot auxiliary controller, a sense coil, an electrically controlled automatic barrier gate, and a duty room control computer. The vehicle must be swiped to confirm the identity before entering. According to the specific conditions of the community, we set up the subsystems of the vehicle access management system at the two entrances and exits of the community (non-contact ID card parking main controller, electronically controlled automatic barrier, inductive IC reader, Chinese electronic display Screen, voice prompt system, PIC logic controller, digital vehicle detector).
(B) System advantages
1, there is a car access card function, to prevent the loss of card:
When the vehicle sensor does not sense the car, the system is not allowed to take the card; after taking the card, the system is not allowed to take the second card; after taking the card, the system can only enter the market with a temporary card, and the monthly card is no longer accepted. Other peer manufacturers have serious card drop phenomenon.
2. 100% card output rate:
Adopting European import card issuer, it has the function of missing card warning and avoids artificial traffic jam caused by frequent card loading. The card output rate is up to 100%. There will be no need for the addition of a manager to assist in the issuance of cards and the IC card will be severely bent and jammed.
3, there is a car reader, a car and a card, to prevent losing the car
Can be set to a car reading card or car-free card in two ways, a car a card, car card combination, coupled with image recognition, voice prompts and other multiple authentication methods, absolutely avoid losing cars.
4, multi-stage car, safe and reliable
Level 1: Sensing to the ground, there is a car that does not drop the rod, even if it senses that the car is in the process of falling, the brake rod will spring back automatically.
Grade 2: Flexible railings. When the vehicle is illegally flushed or accidentally rushed, the system's blocking bar can be opened 90 degrees horizontally due to external forces.
Level 3: The pressure electric wave anti-kicking device can make the brake lever automatically rebound after contacting the object in the falling process, avoiding dragging.
5, Barrier performance is reliable, advanced technology
Based on the use of the most advanced turbine motors, the completely self-produced barriers utilize advanced parabolic elastic balancing mechanisms to provide better landing and landing performance, and at the same time ensure the consistency and stability of the system more effectively.
6, support offline operation, ensure data security
The "Shanghai Yiyuan" company's parking lot system has double safety mechanisms. The reliability is extremely high. Even if the computer fails and the communication is interrupted, the entrance and exit control machine can still operate offline. When the connection is online, the data is automatically uploaded and will not be lost.
7, the combination of graphic and textual, comprehensive and detailed records
The monitoring function is combined with the parking lot management to record all vehicle entry and exit data (including pictures, time, etc.). All data is automatically recorded in the computer. No administrator intervention is required during the entire process, and the administrator cannot modify it.
Even vehicles that have not been swiped and the administrator opens the gates without authorization will have detailed images and time records, strictly prevent internal cheating, eliminate human intervention, protect the interests of investors, and facilitate inquiry and financial auditing.
8, a variety of charging methods, easy management
The system provides temporary charging parking, monthly parking, charging parking, free parking and other ways for customers to choose. And customers can set their own charging standards and charging methods under the authorization card status.
9, international advanced technology, good security, strong ability to expand and upgrade
Using the non-contact IC card technology of the world's most advanced PHILIPS company, the anti-counterfeiting performance is good, there is no direction, and the interference is prevented. The parked vehicle owns an IC card with a unique serial number that cannot be changed. At the same time, it adopts two-way authentication mechanism and multiple encryption technology to uniquely identify and cannot counterfeit imitation, and only the system can issue a recognized IC card to recognize it.
(III) Structure and Function of Parking Lot System
Admission control
Identification: Judging whether the vehicle coming to the credit card has access.
Information record: When reading the card, record the entry time, license plate number, owner identity and other information, save it automatically and backup it for system call.
