The electrostatic discharge sensitivity of the components of the anti-static access control system that take protective measures are very low, many in the range of several hundred volts, such as MOS single tube between 100-200V, GaAsFET between 100-300V, and these single tubes It is impossible to increase the protection circuit; some circuits, especially CMOSIC, adopt the electrostatic protection design, which can significantly improve the anti-ESD level, but most can only reach 2000-4000V, and the electrostatic voltage generated in the actual environment may reach Ten thousand volts (such as Table 1.4 and Table 1.6 in Chapter 1. Therefore, unprotected components are susceptible to electrostatic damage. And as the size of components decreases, this damage will increase. So We said that the vast majority of components are electrostatic sensitive devices and need to take anti-static protection measures during manufacturing, transportation and use, and use ion fans. The necessity of using anti-static access control systems:

1. Realize electrostatic testing and automatic identification of personnel identities. Only when the card is legal and the static test passes, can the barrier pass.

2.Flexible assignment of personnel authority. Assign different permissions to people with different identities. For example, the office manager only needs to swipe the card legally to pass the barrier, and the workshop assembly workers need to swipe the card and pass the static test to pass the barrier.

3. Support left and right foot static test. And only after the static test of the left and right feet passes, can the hand static test continue.

4. Different card readers can be used to support multiple identification methods, including: swiping card, swiping + password, fingerprint, etc. Employees with different permissions can be set to use different identification methods.

5. Time zone time control. 32 groups of time zone tables can be set to support holiday control functions.

6. Through infrared sensors, the system can accurately determine whether employees pass through the barrier.

7. The anti-static access control system displays and records all event data in real time; all entry and exit 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, door 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.

8. Equipment health monitoring. Through the communication server (CS), the management center can understand the operation of each device of the system in real time. When the communication of a programmable logic controller is not normal, a striking alarm prompt will appear.

9. The controller of the anti-static access control system can be networked with the computer through the TCP/IP network, and the communication speed is 100M
