Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in figure 1, a double-chain communication area entrance guard control system applied to a physical protection system comprises a double-chain communication control system, an entrance guard server, an entrance guard main controller, an entrance guard sub-controller, a door structure and a power supply, wherein the door structure comprises a door, a lock, a card reader and a card, the double-chain communication control system comprises a central controller, entrance guard management software is installed on the entrance guard server, the entrance guard sub-controller is connected with the entrance guard main controller through RS485, the entrance guard main controller is connected with the entrance guard server through a TCP/IP network, all the entrance guard main controllers are connected through RS485, the entrance guard main controller is connected with the central controller through a TCP/IP network and RS485, the central controller comprises a CPU, an embedded control system is installed on the central controller, and the card reader and the lock are both installed on the door, the card reader and the lock are connected with the entrance guard sub-controller, two card readers and one lock are arranged on each door, the central controller, the entrance guard main controller, the entrance guard sub-controller, the card reader and the lock are connected with a power supply, and the card is matched with the card reader.
Here, the two card readers provided on each door are mainly used for swiping cards when entering and exiting the door respectively.
Preferably, the power supply is further connected with an indicator light, and the indicator light is connected with the central controller.
Preferably, one sub-controller controls one door correspondingly.
The central controller has the function of automatically switching communication lines, the default mode is that TCP/IP network communication is adopted, and when the TCP/IP network is not communicated, RS485 communication is automatically switched.
The central controller has the function of independent operation of the access control management software, and embedded software is arranged in the central controller to realize data forwarding and storage among all the access control main controllers.
In fact, the entrance guard management software is installed on the entrance guard server, the system is added on the basis of the traditional main split type entrance guard control system, plays the role of data forwarding and storage, improves the stability and the reliability of the whole entrance guard control system, when the entrance guard management software is off-line and the entrance guard server and a TCP/IP network are in failure, data between the main entrance guard controllers are forwarded through the double-link communication control system, for example, a person A generates a card swiping event on the sub-entrance guard controller, the sub-entrance guard controller sends the card swiping event to the main entrance guard controller through an RS485 bus, the main entrance guard controller preferentially sends the card swiping event to the double-link communication control system through the TCP/IP network, if the TCP/IP network is not communicated, the card swiping event is automatically sent to the double-link communication control system through the RS485 bus, and the double-link communication control system automatically forwards the card swiping event of the entrance guard controller to other entrance guard controllers, therefore, the problem of data communication among a plurality of entrance guard main controllers under the condition of entrance guard management software offline, server and TCP/IP network faults is solved, so that the functions of multi-door interlocking, return prevention (anti-sneak-back) and the like among the plurality of entrance guard main controllers are realized, the stability of the entrance guard control system is greatly improved, actually, the double-link communication control system also has a data storage function, and when the entrance guard management software, the entrance guard server and the TCP/IP are recovered to be normal, the data is actively uploaded to the entrance guard management software.
The system can realize the multi-door interlocking function, namely, under the condition that the door 1 is not closed after being opened, the door 2 can not be opened, after the door 1 is closed, the door 2 can be opened, otherwise, under the condition that the door 2 is not closed after being opened, the door 1 can not be opened, after the door 2 is closed, the door 1 can be opened, if the entrance guard management software fails or the entrance guard server fails or the TCP/IP network fails, the double-link communication control system can replace the function of realizing the entrance guard server, so that the whole system can also normally operate, and the safety level is improved.
Anti-retrace (anti-sneak): the method refers to that repeated card swiping on a card reader in the same direction and multiple nested areas enter and exit step by step in the same area cannot violate the entering and exiting logic of the nested areas.
As shown in fig. 2, the control area, the protection area, the essential area is nested three region, need pass in and out step by step, can not stride across regional business turn over, the control area has two entrance guard main control unit, every entrance guard main control unit connects 2 entrance guard branch controllers, every entrance guard branch controller corresponds a door, the protection area has an entrance guard main control unit to have connected 3 entrance guard branch controllers, every entrance guard branch controller corresponds a door, the essential area has an entrance guard main control unit to have connected 2 entrance guard branch controllers, every entrance guard branch controller corresponds a door.
For example, after the card reader in the door 2 entering direction swipes the card, the card reader in the door 1, the door 3, and the door 4 entering direction can not be swiped again, and meanwhile, the card reader in the door 5, the door 6, and the door 7 exiting direction can not be swiped or the card reader in any direction of the door 8 and the door 9 can not be swiped, otherwise, the anti-return (anti-sneak) rule is violated, if the access control management software fails or the access control server fails or the TCP/IP network fails, the double-link communication control system can replace the function of realizing the access control server, so that the whole system can normally operate, and the stability and the reliability are improved.
Compared with the prior art, the double-chain-path communication area access control system applied to the physical protection system realizes data communication among a plurality of access control main controllers through the double-chain-path communication area access control system, realizes important functions of multi-door interlocking, anti-return transmission and the like, can realize independent networking with the access control main controllers through the RS485 communication interface, overcomes the problem that data cannot be interacted among the access control main controllers when a TCP/IP network fails, and realizes the design idea that the access control system is separated from the access control server to operate independently.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
