Network Access Control

What are the factors that affect the performance of the access control controller

November 10 , 2022

According to the communication mode, it is divided into RS-485 communication and TCP/IP type. Access controller is divided into single door controller, double access controller and four access controller.


There are many factors that affect the security, stability and reliability of the access control controller, which are usually manifested in the following aspects.

  Network Access Controller

(1) Distribution of controllers.

 

The controller must be placed in a special weak current room or equipment room for centralized management. The controller and the card reader have the ability of long-distance signal transmission. The general Wiegand protocol cannot be used, because the Wiegand protocol can only transmit a distance of tens of meters. This requires that the access control controller must be placed close to the card reader, which is not conducive to the management and security of the controller. The distance between the well-designed controller and the card reader should be no less than 1200m, the communication mode of RS-485 bus; the distance between the controller and the controller should also be no less than 1200m, the communication mode of RS-485 bus.

 

(2) Anti-vandal measures of the controller.

 

The controller chassis must have certain anti-smashing, anti-prying, explosion-proof, fire-proof, and anti-corrosion capabilities, so as to prevent all kinds of illegal destruction events from happening as much as possible.

 

(3) Power supply for the controller.

 

The controller itself must be equipped with a UPS system. When the external power supply cannot supply power, the access control controller can continue to work for at least a few hours to prevent someone from cutting off the power supply and causing the access control to be paralyzed.

 

(4) The alarm capability of the controller.

 

The controller must have various real-time alarm capabilities, such as fault prompts for access power supply, UPS and other equipment, warning information that the chassis is opened, and communication or line failures.

 

(5) Processing of switching signal.

 

Many signals in the access control system will be output in the form of switch, such as door magnetic signal and exit button signal. Since the switch signal only has two states of short circuit and open circuit, it is easy to be used and destroyed, which will greatly reduce the overall access control system. Therefore, the access control controller cannot directly use the switch signal.

 

(6) Structural design.

 

The overall structural design of the access control controller is very important, and the use of slot-type expansion boards should be avoided as much as possible to prevent poor contact caused by oxidation after long-term use; reliable connectors are used to facilitate wiring and are firm and reliable; The distribution and line direction should be reasonable to reduce interference and enhance anti-interference ability; the chassis layout is reasonable to enhance the overall cooling effect. The access controller is a special control device. Stability and reliability must be emphasized. A sufficient and stable access controller is a good controller. The latest technology and components should not be blindly pursued. The processing speed of the controller is not the faster the better, nor the more concentrated the number of gates, the better.

 

(7) Power supply part.

 Access power supply

The power supply is a very important part of the access control controller. The stable working voltage provided to the components is a necessary prerequisite for stability, but the voltage of 220V is often unstable, and there may be phenomena such as low voltage, high voltage, fluctuation, surge, etc. This requires the power supply part to have good filtering and voltage regulation capabilities. In addition, the power supply also needs to have strong anti-interference ability such as high-frequency induction signal and lightning strike.
