Detailed description of the invention

Referring to figs. 1 through Fig. 5, the utility model is described further.

Referring to figs. 1 through shown in Fig. 3, a kind of interlock door, including at least two safety door 10, each described safety door 10 includes doorframe 12 and door leaf 11, passage is formed between adjacent safety door 10, though it is shown that only two safety doors 10 in figure, but multiple safety door 10 can be set according to demand and ensure security, understand that following function is all as a example by two safety doors 10 for convenience.

With reference to shown in Fig. 4, for the overall architecture of whole interlocking linkage system, can be monitored locking by coordinating security centre, at some in particular cases, interlock door can be that Surveillance center strives for time enough, prevents ruffian from entering indoor.Described safety door 10 is additionally provided with automatic locking device, described automatic locking device is all coupled to an interlock circuit 30, described automatic locking device includes lockset 42 and ECU 41, lock signal is opened in ECU 41 output that described lockset 42 is corresponding when opening, when one ECU 41 sends and opens lock signal, described interlock circuit 30 exports locking signal to remaining ECU 41, when ECU 41 receives locking signal, the lockset 42 of locked correspondence.Described interlock circuit 30 has been also coupled to a shroud module 50, and described shroud module 50 connects Surveillance center, and when Surveillance center sends execution signal, described shroud module 50 shields described interlock circuit 30.Described interlock circuit 30 has been also coupled to alarm module, and described alarm module connects and receives two simultaneously and open lock signal, and after continuing the first Preset Time, reminds user's abnormal conditions.

Understand for convenience as a example by concrete function, make explanations:

1, the lock signal that opens of lockset 42 and correspondence exports: the authentication function of described lockset 42 can be speech verification, swipe the card checking, fingerprint authentication, key etc. can be as the unlocking function of checking, and execution action when unlocking is frame for movement realization, when that is performing, the lock point cooperated must be had on doorframe 12 and doorframe 12, complete to lock a door in the way of mechanical action, same, door opening action is also carried out structure, and the output opening lock signal is divided into two ways, one is to arrange corresponding contact, only contact position can be arranged on correspondence position when unblanking, turned on by contact, send a level signal as opening lock signal；Two is if design is the checking realized by fingerprint, the ground electronic installation such as swipe the card, then from the pin of the license end output of electronic installation directly as opening lock signal output.

2, the logic of ECU 41 and the locking mechanism of correspondence: ECU 41 purpose is in order to realize logic output, the namely function of mutually shielding, if each ECU 41 is configured with an enabling signal end and a locking signal end, when receiving locking signal end, by locking mechanism action, complete the locking performing structure, same if being verified by electronic installation, directly can be directly inputted in electronic installation with locking signal, even when verify correct, the most also cannot unblank.With reference to shown in Fig. 5, for relatively conventional execution structure and lockset 42, when lockset 42 drives driving gear to rotate, two locking bars are driven action, and ECU 41 now receive correspondence locking signal time, control a dead bolt 411 to stretch out, if so performing structure action, will certainly conflict with dead bolt 411, cannot unblank, described lockset 42 is provided with spacing preiection, when described lockset 42 is opened, described spacing preiection links with the execution structure of described lockset 42, described ECU 41 is provided with dead bolt 411, when described ECU 41 receives locking signal, described dead bolt 411 stretches out stuck described spacing preiection to hinder the execution structure action of described lockset 42.When described dead bolt 411 stretches out, between described dead bolt 411 and described spacing preiection, leave gap.

null5、The function of interlock circuit 30: interlock circuit 30 includes two groups of signals，Two groups of number of signals are corresponding with ECU 41 quantity，Realize communication，First group of signal be input open lock signal，Second group of signal is the block signal of output，Under normal circumstances，Locking signal is not had to export，Any one safety door 10 can be normally-open，And if when receiving a startup lock signal，Every other locking signal exports to ECU 41，Circuit logic circuit that is simple and that can be equal to is more，In order to embody the original intention of design，As a example by three safety doors 10，Corresponding each safety door 10 is so needed to configure one three input or gate logic，Each or gate logic three inputs all couple other locking signals，Signal is not had to export under normal circumstances，And when one ECU 41 sends and opens lock signal，Be equivalent to send a driving signal to other three or gate logic，So other three or Men Douhui are changed by level，Output locking signal.It should be noted that this sentences or as a example by gate logic, but do not do and limit to, if equivalence can replace to said function with gate logic, the increase of safety door 10 quantity or few, the utility model protection domain should be belonged to equally.

4, the realization of function of shielding, under emergency situation, function of shielding can be used to form passage smoothly, specific implementation is the function by shielding interlock circuit 30, make the independent control of each ECU 41, or directly send unlocking signal to each ECU 41 to unblank to corresponding lockset 42, make each safety door 10 be held open state；And shroud module 50 is generally disposed in Surveillance center, it is impossible to directly controlled by Migrant women.

5, Delayed Alarm functional realiey, the output of lock signal is opened owing to function of shielding does not interferes with, so the most just can judge whether linkage door is in normal operating condition by the quantity opening lock signal, once it is in abnormality (receive more than one open lock signal), so just output judges signal, controlling time-delay mechanism and carry out time delay, the time exceedes certain value, just controls alarm equipment and reminds user's abnormal conditions；And alarm equipment is configurable to buzzer, warning lamp etc., time delay module can be realized by counter or delay circuit, does not makees at this to limit to.

It should be noted that the transmission of signal can by wired can also be by wireless realization.

With reference to shown in Fig. 1, as a example by two safety doors 10, connection support 20, can also be set between each two safety door 10, by connecting the setting of support 20, ensure the intensity of the passage formed therebetween, simultaneously can be by being achieved in that interlock circuit 30 directly realizes signal by copper cash cabling and transmits, it more difficult to being interfered, security and precision are higher, monitoring arrangement can be set on support 20, such as camera, microphone etc..And the width of passage is unsuitable excessive, one is advisable greatly with doorframe 12 grade, and same can arrange steel sealing plate on support 20 so that whole passage forms confined space；The length of passage is also unsuitable long, affects using effect.

Fit dimension, when steel door frame 12 has lockhole, it is not more than 3mm with the maximum fit clearance of dead bolt 411.Door leaf 11 coordinates free gap to be not more than 10mm with doorframe 12.Door leaf 11 is not more than 10mm with the gap of doorframe 12 binding face, and the unlatching limit of door is not more than 5mm in pass door state with doorframe 12 binding face gap.Proof strength and security.

The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under the utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
