Necessity to establish “Personnel Identity Recognition, Vehicle Management, and Attendance System”
1. Large-scale steel companies face the serious problem of huge losses caused by steel theft every year. Although most large-scale steel companies have established closed-circuit monitoring systems and factory peripheral walls, this has reduced the phenomenon of criminals entering the factory to steal steel to a certain extent. Part of the theft is that criminals enter the factory with fake portrait work permits, or enter the factory through familiar security personnel, so the theft of steel cannot be fundamentally eliminated. The inductive ID portrait card identification and access control system launched by our company can fundamentally solve this problem. The system consists of an inductive ID portrait card, an inductive reader, a controller, a computer network, and a database. At present, large-scale steel companies generally use paper work permits (with portraits) that can be 100% forged or forged. When guards check paper work permits (with portraits), they cannot confirm with the personnel department, causing criminals to enter and exit the factory with false permits. However, the identification card work card of the inductive IC card is indeed different. The built-in inductive chip is the only chip number in the world and cannot be copied. If the criminal purchases the inductive IC card from the card factory to forge the ID portrait card work permit, but the IC card number is not stored Back-end database, so when swiping a card to enter the factory area or swiping a card in the factory area is requested by a patrol team, the green indicator light to confirm the identity is not lit, and the criminals will immediately expose the false identity.
2. As everyone enters the factory to swipe their card, the swiping data (card number, time of entry, door number) are stored in the back-end database for future reference at any time. At the same time, it is a forged ID portrait card work permit. The system will immediately issue a voice prompt to inform which channel has illegally entered. In addition, the surveillance video records the entry of employees and guards on duty at all times, even if the guards deliberately release those Entrants who have not swiped their card or the green light does not turn on will also be found in the future video review. Once there is a problem, the public security agency will provide the staff with the specific time, door number and on-site video when the employee enters the factory area to provide a favorable guarantee for the rapid detection of the case , Fundamentally put an end to the phenomenon of guards deliberately letting go, and collusion between guards and criminals.
3. The system can be expanded. The doors of important parts can be equipped with electric locks or gates, and the persons who enter and exit these doors and the specific time period can be set according to the situation.
4. Since the use of this system, Ansteel has been able to block dozens of illegal intruders every day. Many people in the society who steal steel think it is too difficult to enter the factory (because it is impossible to forge an inductive ID portrait card). Greatly reduce losses.
5. Small investment in the entire project has quick results:
a. The cost of the inductive ID portrait card work permit is lower.
b. The total cost of the system is not high.
c. Fast recovery. By issuing cards to employees, more than half of the investment can be recovered. As the steel theft cases are greatly reduced, huge losses to the enterprise are avoided.
6. At the same time, this system can also perform attendance management for employees of various branches and subordinate units. The use of inductive ID portrait card work permits is smoothly implemented in the factory area for all-in-one cards. Each branch and its affiliates can achieve functions such as inductive access control, attendance, meal sales, consumption, medical care, and bathing. Use this card to manage special departments such as trolley squads and motorcades.
7. The long-distance card reader and controller of the system can also be used for the front-end equipment of foreign-purchased vehicles and vehicle management of the unit.
8. Due to the lack of effective supervision methods, corporate vehicles are often used privately, and the economic losses are great. By issuing driver cards, when vehicles enter the gate of the factory area, they must swipe their cards. The system records the exact time of vehicle entry and exit, which is passed and determined in advance. You can find the problem by comparing the route. The storage and transportation company monitors the entry and exit of the transportation vehicles; the office monitors whether the trolleys are used in accordance with regulations, etc. It effectively solves the problems that cannot be controlled during manual inspections such as the driver’s false report of workload, vehicle missed inspection, and driver’s false report of whereabouts, and at the same time, it also prevents vehicles from entering the non-working area.
9. False reports, misreports, and omissions of attendance by employees often occur. Use the credit card data of employees to enter the factory and leave the factory as the basis for attendance, so that the attendance becomes fair and accurate, and the personnel and labor departments can effectively supervise each unit at any time. And the attendance of the department.
Design overview
Based on its own management needs and the fact that the optical fiber backbone network in the plant has been installed in all gates, the steel company decided to establish an access control management system in the plant to cooperate with the existing monitoring system to thoroughly realize the orderly management of all personnel entering the plant.
According to the actual status of the steel company, after demonstration, a complete system solution is proposed. The design is summarized as follows:
1. Adopt the induction ID card (uEM) as the employee ID card, built-in uEM induction chip, the internal number of the chip is different, and it is unique in the world. The employee ID is printed with colored heads of employees, with high definition, and printed with the employee’s name, number, and department.
2. Established with the database server and management system of the certification center as the core, the database and management system of all gated PCs as the front end, and all the gated ID card reading control equipment as the personnel identity verification point, to establish a covering the whole factory Real-time employee identification system. Within 300 milliseconds after the employee enters the factory and swipes the card at the gate, the employee’s identity will be confirmed by the system, and the name, photo, department and other information will be displayed on the gate’s computer. At the same time, a warning light will indicate whether the identity is legal or not. Speaker) will play the name of the person entering and exiting (this function can be blocked at any time), for illegal persons, the amplifying device will use voice prompts.
3. The system adopts a database. The basic information of the in-service personnel and temporary personnel entering the factory are all stored in the database. After the remote card reader installed in the passage of each gate reads the passer’s card number (the only internal card number in the world) ), immediately sent to the system to confirm the legitimacy of the personnel in the database (in 20 milliseconds), legal or illegal will be driven through the controller in the gate to drive the warning device, the whole process is completed within 300 milliseconds. Considering that a gate has a maximum of 12 card readers (four controllers), each channel can verify the passage of up to 3 people per second, which satisfies the rush of people at work peaks.
4. The controller is specially developed for the large-flow access control system of large steel group companies. It can realize that each channel can verify up to 3 persons per second. At the same time, the drive of the warning device is a unit of 150 milliseconds, which guarantees the requirement of large-flow. At the same time, it technically solves the problem that individual card swiping records are ignored in real-time swiping.
5. In order to meet the needs of mobile identification, a large-capacity handheld card reader with a Chinese character library is specially developed, which can download the card numbers of 20,000 employees for verification and comparison.
6. The card reader stainless steel column and loading shell are specially designed and manufactured for the access control system. The structure is reasonable, and the connection is convenient. It has been successfully used in TISCO’s access control system.
7. The system has been applied to Anshan Iron and Steel Group Company, Taiyuan Iron and Steel Group Company, Jiangsu Shagang Group Company, and Lingyuan Iron and Steel Group Company. The system has complete and mature functions, optimized system structure, and high data processing efficiency.
8. The inductive ID card can realize one card for multiple purposes in the factory area, and can realize the consumption function in the factory area. The card can be recharged in advance and swiped for consumption at the consumption sites and charging service departments in the factory, which is convenient for unified settlement and management.
9. Will my company adopt and? ? The automation department of the iron and steel company cooperates to develop the system application software model, which is really guaranteed? ? The automation department of the iron and steel company has the right to modify the system to facilitate future function additions and conversions.
Technical solution
The steel company’s access control system is built on the basis that the optical fiber backbone network in the factory has been laid out to all gates. Use mature proximity card technology, communication technology, computer technology, database technology, and single-chip microcomputer technology to establish this system. The technology is mature and reliable, and it has been applied in various fields on a large scale.
1. The working principle of the system
2. Network topology structure
3. System technology structure
1. Inductive ID portrait card
The card has a built-in sensor chip and antenna. Only a globally unique serial number (also called “internal code”) is stored in the chip. The serial number of the chip cannot be rewritten or copied. Use uEM imported chip EM4100, read only but not write. The internal code of the card is unique in the world and cannot be copied to avoid the occurrence of fraud. The front of the card is printed with the employee’s photo, name, company and card number. Precautions for printing on the back.
The portrait card is printed with Heidelberg equipment and completed with internal imaging technology.
Order INLAYS for packaging from a chip packaging factory in the Asia-Pacific region designated by uEM in Switzerland. The factory made the WAFER crystal garden provided by Swiss uEM company into INLAYS, and is currently the largest ID chip (INLAYS) manufacturer in China.
The ID chips produced by Swiss uEM are currently of the best quality. Most projects that require high ID card quality at home and abroad use uEM chips, which have a long service life and are stable and reliable. The cost is slightly higher than domestic or Taiwan-made chips.
Thickness: 0.8mm-0.95mm
