ESD turnstile access control system solution:
In many places where the electrostatic protection area (EPA) is set up, the testing of electrostatic shoes and wristbands is carried out by the traditional manual login or supervision method, which is not easy to implement or even full of errors, and it is difficult to obtain the trust of customers and management, which also forms a great potential loophole in the electrostatic grounding of personnel;
ESD turnstile access control system for these shortcomings, put forward a direct and effective solution, to ensure that the operators in the EPA area, have done a good job in personnel electrostatic grounding preparation; And combined with the channel gate as the control equipment of the people flow channel. It can provide orderly and civilized access for people in and out, eliminate illegal access, and quickly open the gate in case of emergency to organize personnel evacuation. In the design of this solution, we fully consider the protection of product quality as much as possible through this system.
Analysis of access control demand
With the rapid development of the electronic industry, the quality of electronic equipment and components has been put forward with higher and higher requirements. In this way, in the early stage of the production of electronic equipment, the electrostatic test of employees is particularly important, but also to realize the automatic identification of employees.
The access control system integrates computer technology, network communication technology, ESD technology, automatic control technology, and induction card technology to realize automatic identification of employees and rapid passing of an electrostatic test. It is suitable for the electrostatic test control of the passageway in important places such as research institute, laboratories, and factories.
Access control Security solutions
The traditional electrostatic protection equipment used in most electronic workshops can not effectively eliminate the electrostatic discharge phenomenon, that is, electrostatic discharge (ESD), which is caused by the static electricity carried into the operation room by the operators. In general, the workers in the workshop will not wear wrist strap equipment according to the regulations, and there is no inspector to check the wearing condition.
Even if there is monitoring equipment, the workers can also make themselves out of the monitoring range, which leads to the meaninglessness of the set of static electricity elimination equipment, and the static electricity can not be released in time, resulting in electrostatic neutralization discharge, In the process of electrostatic discharge, a strong current is generated, and the heat is enough to completely melt the internal circuit of the semiconductor chip;
What’s worse is that only one-tenth of this kind of damage will make the whole components fail before the final test, and the remaining 90% will only cause partial damage to the circuit, that is to say, it can make the defects completely ignored through the final test, and lead to early on-site failure after delivery to customers.
As a kind of access control system, access control turnstile equipment can effectively control the access personnel and orderly pass through the channel system, standardize employee management, save enterprise management expenditure and human cost, and realize the automatic management of employees in and out of the workshop.
After a long time of in-depth research and analysis on the sources of static electricity in the electronic industry, and the investigation on the needs of electronic enterprises, through many years of practical experience, we have successfully integrated a set of static electricity system solutions to prevent the generation of static electricity. The system can effectively release the excessive static electricity on the staff, check the qualified wearing condition of the wrist strap, stop the static electricity outside the production workshop, and eliminate the hidden danger of electrostatic discharge. At present, the system has become an important means of quality assurance for electronic manufacturing component enterprises.
Design principles:
Due to the need for safe and efficient management, the design of an anti-static access control system should follow the following principles:
The practicability of the system
The content of the access control system should meet the actual needs, not flashy. If the one-sided pursuit of the leading nature of the system, It is bound to cause too much investment and too far away from the actual needs. Therefore, The practicability of the system is the first principle to be followed. At the same time, the front-end products and system software of the system have good learnability and operability. In particular, the operability enables the management personnel with primary computer operation level to master the operation essentials of the system through simple training, so as to achieve the operation level of completing the duty task.
The stability of the system
Because the access control system is an uninterrupted long-term work system, and is closely related to the normal operation of our electrostatic workshop, so the stability of the system is particularly important. The system should have more than three years of successful application experience in the market and corresponding customer groups and customer service system
System security
All equipment and accessories in the access control system operate safely and reliably, It should also comply with relevant Chinese or international safety standards, And it can work effectively in a non-ideal environment. The powerful real-time monitoring function and linkage function fully ensure the security of the user environment.
System maintainability
The maintenance of the access control system in the process of operation should be as simple as possible. The operation of the system can work when the power is turned on, The extent to which you can plug it in. And there is no need to use too many special maintenance tools in the maintenance process. From the configuration of the computer to the configuration of the system, the configuration of the front-end equipment has fully considered the reliability of the system.
When we achieve the lowest system failure rate, we also consider that even when problems occur due to unexpected reasons, we can ensure the convenient storage and rapid recovery of data, and ensure that the channel can be opened quickly in case of emergency. The maintenance of the whole system is online, and the normal operation of all equipment will not be stopped because of the maintenance of some equipment.
Description and analysis of design requirements
The impact of ESD on electronic products is not only the damage of products but also the reliability of products (intermittent loss of function). It will lead to the instability of product performance and increase the number of maintenance. This situation accounts for 90% of electrostatic damage. The implementation of an anti-static access control system can effectively prevent the failure of reliability and other problems caused by static electricity.
The system requirements are divided into the following three situations:
1. The employee can pass the three stick gate only after the card is verified to be legal. It is required to display in the real-time record whether the card verification is legal or illegal, as well as the record of employees passing the three stick gate;
2. Employees can pass the three-bar brake only after the card and foot static electricity test are passed. It is required to display in the real-time record the records of card verification legal or illegal, the records of foot static electricity test passing or not passing, and the records of employees passing the three-bar brake;
3. Employees can pass the three stick brake only after they pass the card and static test of hands and feet. It is required to display in the real-time record the records of card verification legal or illegal, the records of hand static electricity test passing or not passing, the records of foot static electricity test passing or not passing, and the records of employees passing the three bar brake.
Each workshop can customize the test mode flexibly according to its own situation.
System overview
ESD turnstile access control system is mainly composed of the electrostatic tester, turnstile gate, central controller, inductive card reader, power supply, remote communicator, management computer, and server. Through the access control system, the access controller analyzes the authority of the swipe card personnel, carries out the corresponding static electricity test, and releases static electricity.
After the test is qualified, the channel will automatically release the static electricity (if the test is unqualified, the static electricity tester will automatically release its static electricity to ensure safety), and the employees can enter the indoor safe environment to avoid the damage to electronic devices caused by the static electricity carried in by the external environment.
Electrostatic tester
Electrostatic tester is the core component of ESD turnstile access control system. It indirectly reflects the electrostatic index of the human body by testing the resistance of the human body, so as to ensure that the tested person is qualified to wear shoes, wristbands, etc. at the same time, it outputs signals to the subsequent components to drive the channel mechanism.
According to the grouping signal of the central controller, the card swiper can be operated in four situations: hand and foot measurement, hand only measurement, foot only measurement, and no ESD detection.
Turnstile gate of access control system
ESD detector and inductive card reader are equipped in the entrance direction of the turnstile gate, and one person can pass through after the card swiping and electrostatic detection are qualified. The outside direction is also equipped with an inductive card reader for the company to set a two-way channel.
The exit turnstile gate is equipped with an out-of-office inductive card reader, which can be set to swipe the card to go out or to go out freely.
Central controller
Save the employee’s information, determine whether the employee is allowed to pass the test according to the card swiping signal, and send it to the electrostatic tester, and then drive the three roller brake mechanism according to the output signal of the electrostatic tester.
Inductive card reader:
Receive the swipe card signal and send it to the central controller for discrimination.
Power supply:
Provide power supply to all institutions.
Remote communicator:
The communication between the central controller and the computer is provided to complete the setting and data acquisition.
Management computer:
Install ESD turnstile access control system management software.
Server (optional)
The existing Microsoft SQL Server database management system of the company can be used to install an ESD access control system database.
Design idea of ESD turnstile access control system
Static electricity tests and automatic identification of personnel are realized. When the card is verified to be legal and the static electricity test is passed (the static electricity is within the safe range), the employee can be allowed to pass through the gate.
Flexible allocation of personnel authority. Humanized design, for different identities of personnel, the allocation of different permissions. For example, office managers and visitors can pass the gate only by swiping the card legally, while workshop assembly workers can pass the gate only after swiping the card and passing the electrostatic test.
Support left and right foot static test. Test the correct wearing condition of wristbands to ensure the real-time electrostatic discharge when employees enter the workshop. Only after the left and right feet pass the static electricity test, can we continue to test the hand static electricity.
Different readers can be used to support a variety of identification methods, including swipe card, swipe card + password, fingerprint, and so on. Employees with different permissions can use different identification methods.
Time zone control. 32 time zone tables can be set to support holiday control.
Through the infrared sensor, the system can accurately judge whether the employee has passed the gate.
Display and record all event data in real-time; All in and out records are transmitted to the computer in real-time and can be displayed immediately in the computer of the management center; Cardholder (name, photo, etc.), event time, gate address, event type, and record truthfully, and the record cannot be changed. When an alarm event occurs, a striking alarm prompt box will pop up on the computer screen.
Monitoring of equipment operating status. Through the communication server (CS), the management center can know the operation of each piece of equipment in real-time. When the communication of a PLC is abnormal, a striking alarm will appear.
The controller can be connected to the computer through a TCP / IP network, and the communication speed is very fast. It can be connected to the computer in a long distance, and the cost of wiring can be reduced by using the existing LAN.
The process of ESD turnstile access control system
After testing, the average time for one person to pass the anti-static access control system is shortened to 5-6 seconds.
Test preparation: the tester shall be prepared for a static test (mainly refers to wearing anti-static shoes) and stand on the metal pad of the tester with both feet.
Identification: the tester pastes the personal identification card close to the inductive card reader, and the reader will sound “tick” when the induction is successful. At this time, the central controller has successfully completed the identification.
Static test: after hearing the “tick” of the reader, touch the test button with the right index finger or press the test button (according to different models) within 5 seconds to carry out the static test.
Access control release: when the indicator light of the tester is all green and the buzzer no longer rings, the tester can pass through the three roller gate, and the three roller gate will lock again after the set time (generally 5 seconds).
After swiping the card, you can go out directly, or you can go out directly without swiping the card.
Functional features:
Automatic identification of radio frequency did card and CIC card
The system uses the radio frequency technology to access the personnel information in the database in real time, so as to quickly identify the personnel information. If you are not registered in the system, you can also identify and mention it.
Antistatic test
The anti-static test instrument can quickly judge whether the tester’s static ring, left foot static shoes and right foot static shoes meet the anti-static requirements. Each channel can be in and out in two directions, greatly improving the utilization rate of equipment. When personnel pass through, the system can automatically identify the in and out direction.
Real time upload of credit card information
Through TCP / IP network, the system can upload the personnel information and the resistance value data to the management and command center in real-time, and can also automatically send the ng data to the mailbox of the management personnel designated by each team.
Multimedia Kanban joint control and monitoring function
A large display screen can be installed in the access control test channel to display the information of unqualified personnel and mark it in red for leaders and customers to watch and verify at any time.
Illegal card alarm function
For those who do not have a card or whose card is illegal, when they pass through the gate channel, they will immediately give an audible and visual alarm. For example, when going to and from work, illegal people and unauthorized people mix into the crowd and try to follow them. The access control system can automatically identify and effectively prevent foreign people from entering, and truly achieve the combination of civil air defense and technical defense.
