Shanghai Nanhui District Xinchang Town Automatic Door Repair Access control installation with IC card 20225165
one, introduction:
Inductive IC card attendance management system is the development and application of computer information technology in the modern company's comprehensive management and automation control. The system uses computer network technology, communication technology, measurement and control technology, high intelligence microelectronics technology, and mechatronics technology for customers. Provides a new and efficient management system, giving full play to the effectiveness of manpower, resources, and space. The system uses a non-contact PHLIP Mifare card technology, avoiding problems of traditional card theft and security against copying the data are transmitted in the air through the DES (Data Encryption Standard- Data Encryption Standard) encryption algorithm ciphertext avoided . Each user holds a separate password information can be established by using a software system or cancel its right to increase or decrease the usage rights, provide a guarantee to prevent card theft and copying; commuting centralized channel ports on staff to staff with The employee's card is based on the reading and writing data on the card reader, and is processed by computer to realize the automatic attendance management ; it solves the inaccuracy of the record of the traditional attendance machine, the employee cheating on the grounds of forgetting to punch or changing the time of punching, etc. The issue provides a reliable basis for the company's personnel management and salary calculations. In addition, a one-card multi-use technology is used to write information on the employee's card to store the corresponding amount of money spent in the canteen or other consumption locations ; the advantages of electronic money are concentrated, and there is no need to change or change tickets to improve the efficiency of selling meals and reduce Human error. Safe and anti-counterfeiting, avoiding economic losses caused by fake cards or fake tickets. With card loss report, blacklist alarm function. No ticket circulation, electronic settlement, blocking internal management loopholes. The computer collects data and generates various types of detailed reports with long life, health and economy.
Increased efficiency, reduced human error, avoided economic losses due to fake cards or fake tickets, and increased card life.
The system adopts the current international advanced network structure to handle intricate and complex control information in a timely and efficient manner, centralize control and management of functional limitations and scattered control and detection units . At the same time, each intelligent controller is relatively distributed and controlled, and when the network fails , Still can continue to monitor and manage according to the pre-programmed program, make the system more complete and effective, operating software based on WINDOWSNT platform to make managers more clear, simple and easy. The system is based on safety, reliability and perfection, applying high technology to create a highly advantageous cost performance, making the system more widely used in hotels, villas, banks, corporate agencies, public security and justice departments and various types of integrated commercial buildings. And residential.
Time and attendance management system with great flexibility, by mounting an MCM MFRW1000A contactless smart card reader, dedicated to collecting attendance data; Further, when the person forgot to bring the card, allows the input number and personal work (common identifier through a keyboard Password ) PIN method for attendance.
MCM attendance system uses all contactless readers and intelligent controllers distributed in the building to collect attendance data. All data can be stored in the intelligent controller and can be transmitted to the system database server through the network. Save, can generate various reports through attendance software running in the server. If necessary, the data can also be transmitted to the database server of the OA system and the attendance software can be run there.
Second, the main equipment selection and introduction:
2.1 Controller
As the core of the system, the controller plays a key role. It is responsible for the centralized control of the bridge, that is, it directly accepts the control instructions of the central monitoring center computer, and controls the field equipment according to the instructions, and at the same time, it will take various situations on the site. Timely feedback to the center. It has all the features of the direct digital controller DDC (Direct Digital Controller) in the distributed control system DCS (Distributed Control System) . It must be ensured that the work can continue in the event of a central monitoring center or network failure. Important data can be saved after the controller is powered off. In order to adapt to this situation, it is necessary to adopt an adaptive intelligent controller to achieve the following functions:
Includes a high fault tolerance, high speed, high reliability;
Take offline operation independently of the network ;
With a variety of forms of control: analog, digital, RS-485 , RS-232 communication control interface.
In order to achieve the purpose of design, a suitable model must be selected among many system intelligent controllers. First, the performance characteristics of various intelligent controllers are introduced:
Intelligent Network Controller probably divided into two types: 1, field bus communication control (CANBUS, LONGWORKS etc.), 2, Ethernet by TCP / IP protocol, and includes a RS-485, RS-232 control interface; it Two kinds of controllers have mature products in the controller of the attendance system of MCM , namely: ACU3000 , ACU5000 intelligent controller, its performance is as follows:
