I. System Overview 

 Non-contact proximity card charges access control system is new and modern safety management system, which combines computer technology, network communication technology, automatic control technology and proximity card technology, security management, the system in use, card is not in direct contact with the device, just shaking in the reader before, the system can collect the required information, such as access control, attendance, elevator management, fees and many other features. Because of its high degree of safety, applicable to a wide range, extremely easy to use and management methods are widely used in factories, entertainment, dining hall, health club, parks, playgrounds and other fixed amount of fee access channel management. 
 Subscription access control system is mainly responsible for the management area (factories, canteens, entertainment) staff access control management, enter each charge a fixed fee. The main solution to pay regional channels out of the automatic identification, unattended, charges admission. 
 Actual use, the staff just made the work card proximity card Akira management gates before the reader, can enter the toll area under the authority, and the deduction of certain costs; the owner's name, the remaining amount and debit amount, no cards, invalid cards or less than the amount the cardholder can not enter the toll area. 
 The program uses 485 networking, various fees and access control through the 485 bus and computer networking. The computer will charge the access control parameter settings, time zone hours, access control group, the card information passed to the various charges and access control, real-time monitoring of personnel charges, toll charges and personnel information. 

 Second, the system components 

 The system consists of subscription access control management software, fees and access control, IC card management gates and 485 converters and so on. 

 (1) charges access control management software 

 Used to add staff information, credit card issuers, centralized management and monitoring of all charges and access control, set the time zone hours, allocation of personnel in and out of each channel of authority, real-time monitoring and statistics out of the fees. 
 The software consists of five modules: communication server, monitor, display terminals, personnel data management module, the access control permissions settings module and toll recharge, and query statistics module. 

 2 charges and access control 

 It is the core of the system as a whole. Each subscription access control has a communication with the computer 485. Can store 1 million cards and 10,000 records. All charges and access control with an alarm relay output alarm signal can be received in fees and access control, driver sound and light alarm equipment. It also shows the amount of fees, charges, balance, fees and information. 

 IC card 

 The program selected Mifare card card stored data are encrypted, safe. The card has 1Kbytes storage space can be used for the storage amount and the name of the person. 
 Printable photos of employees, departments, job number on the card information, and highlights the company's image. 

 Management gates 

 The management of gates for access control, electronic control equipment. Credit card legal, management gates "Activation" to allow people through the buckle and to a certain amount of payments; when the card is not lawful, management gateway machine is not "activate", does not allow people through, not billing. In general, the management action of the gates is a trigger signal is touched once, you can generate a signal, the signal point is connected to the corresponding relay on the toll and access control. 
 Management gates are generally divided into three roller gates, swing doors, drop-arm Barrier. 

 5.485 converter 

 Charges and access control computer via the 485 bus communication, the need to add a 485 converter on the computer side. 




 Third, the implementation of the program 

 Set up a management host system, placed in the center management and monitoring; subscription access control management software installed on the management host, is responsible for the maintenance and management of the entire region of charges; charges and access control for the core components of the system, responsible for the entire system input and output of information processing and storage control. Generally install the device on the swing door in place of charges, all charges and access control via a RS485 bus connection, 19200 baud rate of communication, after 485 converter connected to the management host; 
 Set fees reader points in the charging region swing door, three roller gates or drop-arm Barrier, installation charges and access control; each employee or member is issued a smart card when the credit card in the charges on the access control, toll access opportunities for first checks the card is legitimate and meets the access control, when the legitimate after, then check the card balance, after deducting a certain amount to open the door relay, while the balance and the cardholder's name displayed on the LCD, otherwise not allowed to pass. Each debit a fixed amount set by the controller above the keyboard. 
 Each controller can be set to different deduction rates. As deductions in the 1st controller card 2 yuan, on the 2nd controller card chargeback five yuan. Subscription management software table, the statistics of the consumption of the employees in the different controllers, so this feature is particularly suitable for the consumption of the canteen. 
 When employees or members to prepare the toll area, swing door, three roller gates or drop-arm Barrier other end of the charges and access control on the card, as long as the legitimate card, you can allow passage, the system is no longer chargeback, while credit card control The device LCD display card balance. 
 Into the the fees region records will be quickly sent to the subscription access control management software, management can immediately see the charges, including the fee amount, pay personnel information, charging times etc.. Daily, weekly or monthly, the system can be out of the personnel charges query and statistical data. 
 If the card amount, the relay will not be action on the controller. At the same time, the controller generates a card balance is less than the record to the computer. 
 485 bus of the various charges and access control to the computer using a shielded twisted pair in order to ensure the stability of communication. 

 Fourth, the system functions 

 A. Classification of the designated area, the sub-periods of traffic rights management restrictions on overseas personnel from intruding into the fee area, based on the employee's position or the nature of the work to determine the prevailing level and allow the passage of the period, effective to prevent the unauthorized possession of outside Pirates. 
 Two. Real-time display and record all event data; subscription access control, real-time data transmitted to the computer can be immediately displayed in the management center computer; cardholder (name, photo, etc.), event time, fees, address, event type, faithfully record and the record is not changed. Alarm event occurs, the striking alarm box will pop up on the computer screen. 
 3. With the management of the design of the gates, the system is unattended and charges admission. The system through the control channel management, do not need to guard. Traditional way, you need to guard in the next ticket, or to receive cash directly, both error-prone, but also increases labor costs, when the guard with some staff "relationship" is better, the management will have difficulty. 
 4. Support for the Chinese name display. Subscription access control can display the names of the officers of charges, the amount of fees, charges, balances and credit card time. 
 5 The system can collect a variety of accident signal (Fire, Police, etc.), the timely recording and alarm; 
 6. System coordination linkage through the linkage of output points and building automation, closed circuit surveillance, burglar and fire alarm systems; after receiving the fire alarm signal when the access control system, the system can automatically open all doors in the control region, the control region personnel escape; in important parts installed cameras, the linkage system can automatically switch the camera screen, the need to monitor the site to monitor, and video; 
 8. Charges and access control can be offline (lost contact with the management host) work, and does not affect the access doors; when the charging point and center to re-establish communication, subscription access control function to upload event information in real time;
