●System Overview
This system uses advanced IC card technology to completely concentrate the access control, elevator control, parking barriers, consumption and other functions of the smart office building on a small smart card. If you are a staff member of the smart office building, you only need to hold one An inductive smart card, combined with the identity authentication system, can enter the door by shaking the sensor on the door. The traditional “key” has lost its usefulness in the face of high-tech; if the smart card is damaged or used illegally, always Maintain a high degree of vigilance, the sensor will alarm at the fastest speed.
With this smart card, in the elevator of the building, you can go directly to your office floor without pressing the number of elevator floors; with this smart card, you do not need to get off the car to the parking lot. The automatic sensor will identify the identity of the occupant. Automatically open the barriers; with this smart card, you can use all the facilities of the clubhouse in the building as you like without any money, and purchase what you need within the available range. Of course, the shopping expenses will be recorded in In your name, the bill will be paid on a monthly basis.
●System objectives, structure, design principles
●Goal
Reach the goal of advanced, safe, reliable and practical
●Structure
Using computer network technology and 485 port communication technology, all sensing points are incorporated into the network, real-time viewing and tracking of all incoming and outgoing data, to understand the situation, and achieve the purpose of proper management.
●System design principles
Unified planning and unified design: Carrying out comprehensive demonstration and planning at the initial stage of system design is conducive to the stable operation and actual needs of the system, especially for the pre-planning of one card for multiple purposes, which facilitates the realization of the system.
The system should be expandable and optimized: the entire system is an embedded design, the mature management link should be in place in one step, and the software and hardware construction modules can fully ensure that the system can be expanded, and the front and back designs can be seamlessly combined.
Operation manual, easy to use, standardized management: the system software is simple, reliable, and easy to operate.
Advanced technology: According to the special needs of the office building, several currently mature and stable support platforms (such as WIN95/NT platform) can be used, and the equipment is developed using the most advanced inductive IC card technology in the world.
●Overview of non-contact IC card
Contactless IC card, also known as radio frequency card, is a new technology developed in the world in recent years. It successfully combines radio frequency identification technology and IC card technology to solve the problem of passive (no power in the card) and free Contacting this difficult problem is a major breakthrough in the field of electronic devices.
In addition, the non-contact card selected should comply with MIFAREI International. The card does not have a power supply, has its own antenna, and contains an encrypted control logic circuit. The communication between the card and the reader adopts the internationally accepted DES and RES confidential cross algorithm, which has extremely high confidentiality performance.
●The realization of the system
According to the characteristics of the above-mentioned card and the actual situation of the office building, the following plans are made for the card in the system:
Personal information area: name, card issuance date, ID number, brief description less than 16 bytes (such as: contact phone number, simple work unit code, home address code, etc.)
Application area (1-5)
Record content:
Initialization date
Last used date
Initialized data (according to different applications, there can be corresponding format design)
Latest information
Consumption code
Systematic organization planning
On the basis of the successful networking, the card issuing center issued membership cards of different levels to each member of each unit. The card records the detailed information of the household, and the household can “all-in-one card” at various induction points and consumption points as they wish.
●Systematic elaboration
Parking barrier
There is no need to get off when parking, just take the card and shake it above the entrance sensor. After the sensor automatically authenticates the identity, the barrier will automatically open and record the time of entry. If the card is illegal, the sensor will automatically alarm and the barrier will not open. The sensor in the exit parking lot will also identify the identity, so that only the legal person can exit the barrier to automatically deduct the parking fee for the parking time.
Attendance
The attendance system is a non-contact IC card attendance machine combined with a non-contact IC card and related attendance software. Really and objectively record and count the attendance of each staff member, and can be linked with related financial software to facilitate the financial staff to carry out salary settlement.
Access control
The access control system includes office building gates, building gates, office gates, and staff entering and exiting different doors with different settings. The office building gates can be freely entered and exited as long as legal staff are allowed to enter and exit, and the time of entry and exit is recorded in real time; the building gates have only The personnel in the building can enter and exit freely, and the time of entry and exit is also recorded. Of course, only you can enter and exit your own office, and the system will also record the time. The manager can check the entry and exit status of each door at any time, which is convenient for the management office to manage.
elevator
Different permissions authorized by the management office to different personnel, some can only reach their own floors, and some can be authorized to different floors, which can be completely controlled by the management office, which is convenient for management. Each time the use time is recorded, the management office can see the elevator’s status at a glance. Usage.
canteen
The meal selling system in the canteen of the building is to install a corresponding number of non-contact IC card vending machines in the dining area to facilitate the meals of the working staff. The system is equipped with a variety of ways to sell meals, so that the staff can freely choose their favorite meals. .
Clubhouse consumption
In the clubhouse, people who have the right to spend can easily entertain and shop everywhere in the clubhouse (but not for cards that are not authorized to spend, such as clerical personnel cards). The computer will automatically record consumption and entertainment, and the deduction system will check accounts every month. When there is no money in the account, the consumer will automatically alarm to remind you to deposit money into the account
