Aiming at the problem that the control precision of the traditional high-speed rail operation door system to operators is insufficient, the invention provides a door control management system and a door control management method based on a face recognition technology.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a face recognition door control management system comprises an operation door, an automatic door lock mechanism, an access control card and a remote management end.
The remote management terminal comprises a server, a card sender and a remote communication assembly.
The automatic door lock mechanism comprises a bolt, an electric control transmission assembly and a magnetic card sensor. The bolt structure can be a door lock structure only comprising a latch bolt, or a door lock structure comprising both the latch bolt and a square bolt/cylindrical bolt.
The operation door is provided with a camera assembly, a lock tongue linkage rod connected with a lock tongue and an electric lock assembly arranged in the operation door.
A remote communication connection relation is established between the camera assembly and a server of a remote management end, so that the camera assembly can transmit the collected face information to the server.
The lock tongue linkage rod can synchronously move along with the reciprocating movement of the lock tongue, and an arm plate is formed at one end inserted into the operation door.
The electric lock assembly comprises a suction plate and an electric lock body bearing structure, the suction plate is arranged on an arm plate of the spring bolt linkage rod, and the electric lock body bearing structure is fixed on the operation door.
The electric lock body fixed on the electric lock body bearing structure is connected with a power on/off controller arranged on the operation door, and a communication connection relation is established between the power on/off controller and the server, so that the server can remotely control the power on/off condition of the electric lock body.
In the operation of opening and closing the operation door, the spring bolt of the automatic door lock mechanism moves out and moves into the spring bolt hole on the door frame, so that the spring bolt has the reciprocating motion stroke. The design purpose that the lock tongue linkage rod can synchronously move along with the reciprocating movement of the lock tongue can be realized by connecting the lock tongue linkage rod with the lock tongue.
The spring bolt is linked with the action of the spring bolt linkage rod, the design purpose that reciprocating movement of the spring bolt linkage rod can enable the suction plate to correspondingly move to the upper part of the electric lock body and move away from the upper part of the electric lock body is met, the operation door is in a closed state when the suction plate correspondingly moves to the upper part of the electric lock body (the spring bolt at the moment is in a spring bolt hole in a door frame), and the operation door is in an open state when the suction plate moves away from the upper part (right direction) of the electric lock body (the spring bolt at the moment is outside the spring bolt hole arranged in the door frame).
When the suction plate moves to the upper part of the electric lock body, the electric lock body in the power-on state and the suction plate are attracted and connected through electromagnetic force to limit the movement of the lock tongue linkage rod, so that the lock tongue cannot move out of a lock tongue hole in a door frame, and at the moment, the door cannot be opened even if the door access card is swiped.
When the electric lock body is in a power-off state, when the bolt moves rightwards and moves out of the bolt hole on the door frame, the suction plate moves to the right side of the upper part of the electric lock body.

Detailed Description
The structures, proportions, and dimensions shown in the drawings and described in the specification are for understanding and reading the present disclosure, and are not intended to limit the scope of the present disclosure, which is defined in the claims, and are not essential to the skilled in the art. In addition, the terms "upper", "lower", "front", "rear" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the relative positions may be changed or adjusted without substantial technical changes.
The patent relates to a face identification door control management system, like the operation door management system in the past, including operation door, the automatic lock mechanism of dead bolt formula, entrance guard's card and remote management end. The remote management terminal comprises a server, a card sender and a remote communication assembly. The automatic door lock mechanism comprises a bolt, an electric control transmission assembly and a magnetic card sensor.
As shown in fig. 1 and 2, the face recognition gated management system further includes a camera assembly installed on the operation door 100, a latch linkage rod 1 connected to the latch, and an electric lock assembly installed in the operation door 100. The camera assembly is in remote communication connection with the server. The lock tongue linkage rod 1 can synchronously move along with the left and right reciprocating movement of the lock tongue, and an arm plate 11 is formed at the right end. The electric lock assembly includes a suction plate 12 mounted on the arm plate 11 and an electric lock body bearing structure fixed to the service door 100.
The electric lock body 31 fixed on the electric lock body bearing structure is connected with a power on/off controller arranged on the operation door 100, and a communication connection relation is established between the power on/off controller and the server, so that the server can remotely control the power on/off condition of the electric lock body.
The reciprocating movement of the deadbolt linkage rod 1 enables the suction plate 12 to move correspondingly above the electric lock body 31 and away from above the electric lock body 31. As shown in the figure, when the suction plate 12 moves to the upper part of the electric lock body 31, the electric lock body 31 in the power-on state can be attracted and connected with the suction plate 12 by electromagnetic force to limit the movement of the bolt linkage rod 1, at this time, the bolt cannot move out of the bolt hole because the bolt linkage rod 1 cannot move rightwards, and the operation door cannot be opened.
The server can correspondingly match the face information of the operator recorded and stored with the operation door in the skylight period.
The server can compare the face information matched with the operation door with the face information collected and transmitted by the camera assembly of the operation door, and the electric lock body can be controlled to enter a power-off state for a period of time if the processed face information meets a set matching threshold.
For example, face information of a plurality of operators, such as a, b, c, d, e, f, and g. And (4) screening the operators with the current value by the server according to the number of the operation doors in the skylight period to be overhauled or checked. For example, the server can allocate the face information of four workers (of current values) a, b, c, d and e to A, B, C, D, E four working doors in the skylight period respectively.
After the camera assembly on the operation door A transmits face information of an operator, the server can compare the face information with the face information distributed to the operation door A, at the moment, the electric lock body of the operation door A is controlled to enter a state with a period of power-off time if a threshold condition is met, the operation door A can be opened after the operator swipes an access control card, in the state with the period of power-off time, the operator enters the operation door to implement operation and closes the door after the operation is completed, the server enables the electric lock body of the operation door A to be powered on after the set time passes, and at the moment, the operation door A cannot be opened even if the access control card is swiped. After the face information is compared with the face information of the same person, the power-off time of the electric lock body is basically equal to the time required by an operator to enter the operation door to carry out operation. Certainly, a sensor can be arranged in the bolt hole, when the bolt is moved out of the bolt hole and then inserted into the bolt hole again and the end part is pressed on the sensor, the sensor can feed back a sensing signal to the server, so that the server sends an instruction to the power-on and power-off controller of the electric lock body of the operation door A, and the electric lock body of the operation door A is powered on again.
After the camera assembly on the D operation door transmits the face information of the operator c, the server can compare the face information with the face information distributed to the D operation door, if the threshold condition is not met, the server does not perform feedback processing, the electric lock body of the D operation door is still kept in a power-on state, and the operator c cannot open the D operation door after swiping an access card.
As shown in fig. 1 and 2, the mating structure between the suction plate 12 and the arm plate 11 enables the suction plate 12 to float up and down relative to the arm plate 11 (as shown in fig. 2) and/or the mating structure between the electric lock body 31 and the electric lock body carrying structure enables the electric lock body 31 to float up and down relative to the electric lock body carrying structure (as shown in fig. 1). When the suction plate 12 moves above the electric lock body 31, a gap is formed between the opposite surfaces of the suction plate 12 and the electric lock body 31, and the electric lock body 31 can be attracted and contacted with the suction plate 12 to be integrated when being electrified by the up-and-down floating motion of the suction plate and/or the electric lock body.
The door lock of the operation door can adopt the forms of an automatic door lock mechanism and an access card besides the structural mode of manually rotating the handle to enable the lock tongue to act. The access control card is close to the magnetic card inductor, so that an induction signal can be fed back to the server of the remote management end, and the server receives the fed back signal and sends an action instruction to the electric control transmission assembly, so that the electric control transmission assembly drives the lock tongue to act, and the opening and closing of the operation door are controlled.
The electric lock body bearing structure comprises a bearing block 2 fixedly arranged in the operation door 100 and a mounting block 3 correspondingly matched with the bearing block 2. The bolt linkage rod 1 can move synchronously along with the movement of the bolt. An arm plate 11 is formed at one end (namely the right end) of the lock tongue linkage rod 1 back to the lock tongue, and a suction plate 12 is arranged on the lower end face of the arm plate 11.
The assembling block 3 is correspondingly arranged on the upper part of the bearing block 2, and the assembling block and the bearing block are matched through an elastic supporting and connecting structure, so that the assembling block 3 can reciprocate in the vertical direction relative to the bearing block 2.
The upper end face of the assembling block 3 is provided with an electric lock body 31, the electric lock body 31 is connected with a power on/off controller arranged in the operation door 100, and a communication connection relation is established between the power on/off controller and the server, so that the server can remotely control the power on/off condition of the electric lock body.
The reciprocating movement of the deadbolt linkage 1 enables the suction plate 12 mounted on the arm plate 11 to move to and from the upper portion of the electric lock body 31 correspondingly. When the suction plate 12 moves to the upper portion of the electric locker 31, the electric locker 31 in the energized state is electromagnetically attracted to and coupled to the suction plate 12.
The end face of the bearing block 2 opposite to the assembling block 3 is provided with a first boss 21 and a second boss 32 which are correspondingly matched, specifically: the bearing block 2 faces the end face of the assembling block 3 and is provided with a first boss 21 and a second boss 32, and the end face of the assembling block 3 faces the bearing block 2 and is provided with a left boss and a right boss.
The two bosses I21 correspond to the two bosses II 32 respectively, and the matched bosses II 32 are positioned on the left side of the bosses I21. The first boss can be right like this with the matching of boss two the assembly piece 3 is relative the distance that the direction (right) that deviates from the spring bolt of support block 2 orientation removed forms the restriction, and the electric lock body 31 with the suction plate 12 inhales mutually and can play the restriction when connecting as an organic whole the purpose that the direction (right) of spring bolt gangbar 1 back to from the spring bolt removed, the spring bolt just can not remove like this, even if brush entrance guard's card operation door also can not be opened this moment. The upper end face of the boss first 21 is required to be always kept above the lower end face of the boss second 32.
When the electric lock body 31 is in a power-off state, a vertical distance is formed between the opposite surfaces of the bearing block 2 and the assembling block 3, and the arrangement of the distance can avoid that the suction plate 12 of the bolt linkage rod 1 generates moving friction when the electric lock body 31 moves relative to the suction plate, so that the service life of the corresponding accessory is influenced.
Due to the floating lifting characteristic of the assembling block 3, when the electric lock body 31 is in a power-on state, the magnetic attraction force generated by the electric lock body 31 can urge the electric lock body 31 and the suction plate 12 to be attracted and contacted into a whole.
By means of the characteristic that the upper end face of the first boss 21 is always kept above the lower end face of the second boss 32, the assembly block 3 is guaranteed to play a role in limiting the movement of the bolt linkage rod 1 after floating upwards and being sucked with the suction plate 12 into a whole.
Specifically, the camera assembly can establish a telecommunication connection with the server. The server comprises a face information storage module and a face information configuration and comparison processing module.
The face information configuration and comparison processing module can select certain face information from the face information storage module and configure the face information to a corresponding operation door, can compare the face information collected and transmitted to the server by a camera assembly arranged on the operation door with the configured face information, and enables the electric lock body to enter a short-time power-off state when the matching threshold value is met after processing, and at the moment, the access control card can be opened when corresponding to the operation door. That is, when the server controls the electric lock body to enter the power-off state, the electric lock body releases the limiting effect on the suction plate, so that the bolt linkage rod can move back and forth along with the bolt, and the operation of opening and closing the operation door can be carried out.
The upper end face of the bearing block 2 is provided with a sinking groove. The mounting block 3 is supported in the sink by the resilient arms 33 provided at its ends being connected to the left and right walls 22, 23 of the support block 2. A U-shaped block 24 is arranged on the right wall 23 of the carrier block 2, the two arms of the U-shaped block 24 being inserted into profiled holes provided in the right wall. The right wall plate 23 is provided with a screw 25, and the end of the screw 25 can be screwed into the sinking groove to push the U-shaped block 24 to move in a direction away from the right wall plate 23. Resilient arms 33 provided on the mounting block 3 mate with the U-shaped blocks 24.
As shown in fig. 2 to 3, the matching structure between the suction plate 12 and the arm plate 11 enables the suction plate 12 to float up and down relative to the arm plate 11. In particular, the amount of the solvent to be used,
the arm plate 11 is provided with a sinking groove for accommodating the suction plate 12, and a cover plate 13 is fixed at the end opening of the sinking groove.
The cover plate 13 has a through hole formed on the surface thereof for the suction plate 122 to pass through. A plurality of holes are distributed on the cover plate 13 at intervals around the circumference, and each hole is respectively matched with a stud 14.
The inner end of the suction plate 12 is provided with a flange 121, and the flange 121 is provided with through holes which are correspondingly matched with the holes on the cover plate 13 one by one.
One end of the stud 14 passes through a through hole on the flange 121 of the suction plate 12 and then is connected in a threaded hole arranged on the bottom surface of the sinking groove.
Each stud 14 is sleeved with a spring 15, and both ends of the spring 15 are arranged between the inner end surface of the cover plate 13 and the flange 121.
After the electric lock body 31 is electrified, the suction plate can be attracted to move downwards, so that the lower end face of the suction plate moves out of the through hole of the plate face of the cover plate 13 and is attracted and contacted with the electric lock body into a whole. After the electric lock 31 is powered off, the magnetic force is lost, and the elastic force of the spring pushes the suction plate to move towards the sinking groove of the wall plate 11, so that the lower end surface of the suction plate 12 gradually retracts into the plate surface through hole of the cover plate 13.
The preferred design is as follows: the access control card is provided with a locator, an identity module and a communication module are embedded in the locator, and the communication module can establish a communication connection relation with the server.
The server can pair the access card with an operator through the identity module of the access card; the position of the operator can be fed back to the server in real time through the positioner on the access card.
