The application of fingerprint authentication technology in the Chinese market has lasted more than ten years from 1993 to the present, and it is basically synchronized with the international level. In the application of fingerprint identification in the Chinese market, the application of fingerprint access control has suddenly emerged. From a technical perspective, fingerprint access control is a high-end product with high quality requirements. Through years of training, domestic manufacturers have made the product performance perfect, occupying a large part of the share and position.
Central Control Fingerprint Access Control System is an access control system that uses biometric technology, computer technology, integrated access control, time attendance access control, access control management and personnel management software. The staff do not need to keep and carry various documents such as paper cards or IC cards, etc., just a light touch of the finger can complete the identification to achieve the purpose of opening the door, checking attendance and access control. Ensure the security of the doorman, the fairness of the attendance and access control, the statistics of the records, and the accuracy of the data. The uniqueness of fingerprints completely eliminates imposters, and the unnecessary trouble caused by false information to us. Only a qualified person needs to press his finger gently, and at the end of the month, the management staff can operate the computer to easily print the data in and out. Access control management, personnel attendance and access control reports, and attendance and access control management are all computerized to ensure the fairness, fairness, science and accuracy of access control, attendance and access control management.
two.product description
1.Fingerprint recognition
Biometrics is one of the most advanced and reliable identification technologies today. It uses the fixed physiological characteristics of the human body as an identification technology to confirm identity. Fingerprints are a commonly used one. , Island shape, compound shape, left bucket pattern, right bucket pattern, left skip pattern, right skip pattern, triangle area and center point position identification comparison to determine whether the fingerprint comes from the same person.
2.Fingerprint algorithm
Fingerprint algorithm is a mathematical model description of fingerprint identification and judgment rules established according to fingerprint identification requirements and computer program design rules.
Biokey algorithm is a fast and accurate 1:N fingerprint recognition algorithm. When using Biokey for fingerprint recognition (2000-6000 fingerprints), it can be within 1-5 seconds without pre-sorting fingerprints by name, PIN, etc. ( The following tests are all easily completed in the Pentium III 900MHz + 128MB memory environment). After continuous upgrading and improvement of the Biokey algorithm, the 2004 version of the latest algorithm adds a 1:1 comparison method on the basis of fingerprint recognition 1:N, which further improves the fingerprint recognition rate and recognition speed.
three.Design goals
This program has participated in and guided the construction of multiple enterprise personnel time and attendance access control system projects for many times, and has learned a wealth of experience and lessons from practice. According to the different actual requirements of customers, the overall system program design goals meet the following points:
1.High reliability
“Reliability” should be put first in the selection of time attendance and access control system products. Fingerprint products eliminate generational card punching, and the false alarm rate is minimized.
Fingerprint time attendance and access control system products will be used for a long time. Personnel management occupies a very important position for a company. It is a test of long-term normal operation in various complex user environments. Products with higher reliability can effectively reduce the maintenance cost of the system, and are easy to manage to avoid various disputes.
Fingerprint time attendance and access control systems on the market are now uneven. Many products are not formal and have many hidden dangers. Fingerprint time and attendance access control machines are not highly recognized, have a high false treason rate, poor fingerprint recognition, and time-consuming and time-consuming card punching, causing unhappy employees. The credit card data is lost, the software is immature, it fails to meet the company’s attendance and access control requirements, and the technology is not good enough to help the company solve specific problems. Once a problem occurs, maintainability is poor. The central control fingerprint time attendance and access control system recommended by us is second to none in the country in terms of system reliability.
Equipment with extremely strict performance requirements requires our entire system to operate stably for a long time. Products that have not been tested and used on a large scale are very risky for developers. Our professional system equipment, thousands of products are used in large and medium cities across the country, and products are continuously improved. Performance makes the product more reliable and users more trustworthy. Facts have proved that some engineering companies blindly choose low-cost and inferior fingerprint time attendance and access control systems and other products, resulting in poor identification of attendance and access control after the event, which not only causes management confusion, but also interferes with the normal life of enterprises and units. In the end, the entire system is paralyzed and seriously corrupted. The reputation of sellers has been improved, causing huge economic losses.
2.Good applicability
The use of fingerprint time attendance and access control system products must ensure the characteristics of the product’s civilian use, simple use, operation, and maintenance, and high cost performance.
The fingerprint time attendance access control system completely replaces the traditional security measures and undertakes the corporate personnel time attendance access control task, which puts forward higher requirements on the system’s technical performance and ease of operation. First of all, the fingerprint time attendance access control system must ensure a certain technical complexity, can always identify the fingerprints of employees under various conditions, can always be in working condition to meet the attendance access control needs of different personnel, and keep close contact with the attendance access control management computer at all times, which is convenient The personnel management personnel can check the employee’s attendance and access control from time to time.
The product we recommend has simple operation functions, such as simple input in the corresponding menu on the fingerprint time attendance access control machine, and then enter the employee’s data information, usually one finger can complete the entire time attendance access control. The operation of the software is very user-friendly and can be easily mastered with a little understanding of computer applications. At the same time, the system is easy to maintain, easy to maintain, and beautiful.
3.Good economy
The model selection and cost of the fingerprint attendance and access control system should match the enterprise level and protection requirements, and the economy is good. Our fingerprint time attendance access control system has simple wiring, powerful functions and low cost.
Personnel time and attendance access control requirements are relatively high. Objectively, due to the large number of employees and large space requirements, the performance and function requirements of the fingerprint time and attendance access control system are strict. Therefore, the selection of time and attendance access control products should pay special attention to the premise of ensuring performance and functions to avoid cost Too high, pay attention to the function application.
Four.Central System Overview
Fingerprint Time Attendance and Access Control System uses Supcon Golden Fingerprint Time Attendance and Access Control All-in-One F7 as its hardware part, and the software part is composed of its standard software, equipped with a configurable SQL database as its back-end management as required. The time and attendance access control machine can be connected to the hardware in RS232/485 (serial port) or TCP/IP (network) mode. Wiring should be based on customer requirements and site specific conditions.
