Double door each other is locked up in entrance guard system and prevent the imp

Entrance guard system serves as a when how defend a system important subsystem, have the characteristic that is on guard actively, cooperate all sorts of hardware report locks, will inbreak illegally of refus at the door outside. Double door each other is locked up and prevent follow at sb' heels to regard the characteristic of entrance guard system as the function, can achieve security the entrance guard with taller, more stubborn dependability controls government. Current, the manufacturer that produces entrance guard system begins to produce double door to each other is locked up and defend product of follow at sb' heels. It basically applies at bank, telegraphic, postal wait for the place with security personnel higher performance. Double door each other is locked up and defending product of follow at sb' heels is lock and controller (namely entrance guard) the product that whole considers to be designed as a whole, system of entrance guard of general and pure support cannot implement the function that prevents each other of double door of follow at sb' heels to lock up a product to ask. Below, how does the author realize double door to each other is locked up and prevent function of follow at sb' heels to undertake elaborating in entrance guard system, undertake discussing with the person of the same trade inside course of study. Double door each other locks up lock of each other of functional double door, it is the function that shows two doors have each other to lock up linkage, when be being opened when a door namely, another door will be not opened, shut when two doors only when, ability opens among them either path door. After and every are passed must locking up its when a door, a door after ability is entered, if enter the first door hind,this is not locked up good, criterion will cannot enter the 2nd gate. Must pass identity attestation when entering every gate, identity identifying equipment can be used read card implement, if the biology such as dactylogram appearance, control body appearance identifies equipment,also can use. Double door each other locks up a function to control the open of the door namely, and the open of the door is by electronic-controlled of the lock / break electric pilot, electronic-controlled the lock carries out equipment as front, get the control of entrance guard equipment, so, when can be control door opened, in the final analysis, control entrance guard equipment when to can be received namely, processing comes from identity identifying equipment or go out the effective attestation information of pushbutton or go out request. It is with entering place of safety from public division exemple, be in when control body control body appearance after 1 attestation is effective, the door 1 be in open condition, right now, want appearance of screen control body 2 and go out pushbutton 2, make its are in blame make can condition, be in right now namely control body appearance 2 make cross control body attestation or press go out pushbutton 2 cannot spark electronic-controlled lock 2 make the door 2 by open. Become only the door 1 close, and electronic-controlled after locking up 1 electrify, control body appearance 2 and go out pushbutton 2 be activationed afresh, be in make can condition, can accept control body gift 2 or go out the operation of 2 requests pushbutton. No less, be in when control body control body appearance after 2 attestation are effective, the door 2 be in open condition, right now, should appearance of screen control body 1 and go out pushbutton 1, in order to ensure the door 1 cannot by open. Become only the door 2 close, and electronic-controlled after locking up 2 electrify, control body appearance 1 and go out pushbutton 1 ability is activationed afresh. The key that function of lock of double door each other realizes depends on control of entrance guard system when detecting screen of He Xin date / activation why equipment, define dot of a screen and an activation point namely, above pass a control effectively or go out pushbutton signal is screen dot, the door closes and electronic-controlled lock electrify is activation dot, should dominate good screen only (blame make can) with activation (make can) nod twice this, lock of lock of double door each other, much door each other can come true. Linkage of equipment screen, activation, incident, undertake installing through software of entrance guard management, download entrance guard controller next, the system can move all the same below off line condition. Have double door each other to lock up entrance guard system of the function, basically have kind of two kinds of implementation, one kind is the special controller that designs production technically for this function; Another kind is to pass software of entrance guard management to install implementation. Latter passes software setting, the double door each other that can realize different extent is locked up, each other of double door of OK and aleatoric set is locked up, each other of much even door is locked up, systematic government convenient, expansibility is stronger. Prevent function of follow at sb' heels to prevent function of follow at sb' heels, it is to point to prevent to be not accredit personnel, use after holding calorie of person to enter controlled area legally electronic-controlled the time gap that door lock did not close follows entered function. Open the door to, the case that much person enters, bring into threatening warning function, do not discuss range in the article. In system of entrance guard control, prevent function of follow at sb' heels to be able to try to ensure and come true through a variety of means.
