6. Functions of turnstile controller
interface
The turnstile controller can be connected with the pedestrian turnstile gate
identification device, motor, indicator light, and infrared switch respectively
through the control interface, motor interface, light interface, and infrared
interface. The turnstile gate control has a higher degree of integration, which
can simplify the connection relationship of turnstile gate control and make the
wiring simpler, so as to reduce the wiring material cost and labor cost of
installing the turnstile gate.
The turnstile controller is used to receive the opening command sent by the
identity recognition device, control the motor to open the gate according to the
opening command, and switch the control indicator from red to green; The
turnstile controller is also used to judge whether pedestrians pass the gate
according to the infrared signal collected by the infrared switch. If they pass
the turnstile gate, control the motor to close the gate and switch the control
indicator from green to red.

7. The turnstile controller is used to generate the status
information of the turnstile gate and send the status
information to the display device for display; The turnstile
controller can also receive the parameter information input by
the operator through the operating device and change the
state of the turnstile gate according to the parameter
information. The display device and the operating device need
to be connected with the turnstile controller respectively;
The turnstile controller can generate the status information of
the turnstile gate, such as gate opening or closing, and send
the status information to the display device for display. The
operator can view the status information of the turnstile gate
through the display device. In some special cases, when it is
necessary to keep the gate open or closed all the time, or
temporarily need to skip the normal control logic of the turnstile
controller to change the state of the turnstile gate, the operator
can input parameter information through the operating device,
such as opening or closing the gate, Thus, the turnstile
controller is controlled to change the state of the turnstile gate.

8. Turnstile access controller
The turnstile access controller is a kind of controller in the TCP/IP access control system. It uses standard
industrial TCP/IP network communication. In one management system, the number of equipment is not limited. It
can be connected with two Wigan card readers to swipe cards in and out of one entrance. The turnstile access
controller has a built-in web management platform, which can directly set and manage the controller. The simple
control circuit is generally realized by the main control board and card reader, while the complex control circuit
(such as subway AGM) needs to be configured with a special industrial computer.
Its communication distance can reach 1200 meters. It is externally connected with two Wiegand card readers to
realize two-way in and out card swiping. Four switch signals control the output. It has the characteristics of stable
performance, fast communication, large capacity, strong compatibility, and convenient networking. It can be used
in the access control all-in-one card project together with other access control controllers, Its excellent
performance has been widely confirmed in many large-scale access control system projects and all-in-one card
systems at home and abroad.

Anti sneak back function of access controller
What is the anti sneak back function in the function of the access control system?
What is the anti sneak back function and how to implement it:
Some access control manufacturers in the market support anti sneak back function,
but some access control controller products do not support this function.

12. It is difficult to understand the word “anti sneak back”, and it is difficult to analyze its specific function from the word
level. In fact, its explanation should be to prevent a person from entering many times without a record. How can a
person just go in but don’t come out? It seems impossible to think about it, but in real life, this kind of thing often
happens, and there are many opportunities.
For example, when we go to various exhibitions, each of us will be given a pass. This pass can be valid within three
days, and the pass must be brushed on the equipment in and out. When entering, we can pass only after brushing
the pass, and when leaving, we can open the door only after brushing the pass.
Without the anti sneak back function, the following problems will arise: after a person swipes his card with a pass, he
throws the pass from other places to another person to swipe his card. In this way, a pass can allow multiple people
to enter, and then the illegal elements have an opportunity to take advantage of it.
The situation with the anti sneak back function is completely different: after a person swipes his card with a pass, he
must swipe his card on the outgoing card reader before he can swipe his card in again. If he doesn’t swipe his card
out on the outgoing card reader, even if you have a pass, you can’t swipe your card on the incoming card reader. It’s
the same when you go out. It’s impossible to swipe your card twice on the card reader.

13. Through the above analysis, it can be seen that
the anti sneak back function effectively controls
the possibility that a card can allow multiple
people to enter, thus ensuring the authority of one
person and one card. In this way, users will not
lend the card to others casually, and effectively
avoid collusion between internal and external
personnel to engage in illegal activities.
The anti sneak back function is applicable to any
occasion where access control is installed. It
depends on the user’s requirements for the
access control manufacturer and the level of
access control security to determine whether
some functions need to be installed.
The anti sneak back is an anti-tailing function of
the access control system. In some specific
access control occasions, cardholders are
required to swipe their cards from a certain door
when they swipe their cards from a certain door,
and the swiping records must be strictly
corresponding one in and one out.

14. If someone follows others into the door, he doesn’t swipe his card. Next time, he can’t swipe his card, even if
his card is a valid card.
Similarly, if you go out with others and don’t swipe your card, you won’t be able to come in next time. If
someone swipes the card to enter the door and hands the card to the outside person from the window, the
outside person cannot enter the door by swiping the card. If a person doesn’t go in after swiping his card, he
won’t go in next time.
The anti sneak back function is generally used in military, national defense, scientific research, and other
occasions with strict management.
The above is the most common anti sneak back inside and outside of the door. The double door and four-door
access controllers of wiegand can also make the two doors of the same controller anti sneak back to each
other. That is, the cardholder enters from the door a and must come out from door B. This function is mainly
used for channel management and ticket management.
