Further, be connected with clock module on the said single-chip.
Further, be connected with reservoir module on the said single-chip.
Further, be connected with manual control module on the said single-chip.
The principle of work of the utility model is:
This controller mainly is made up of RFID card reader module, gate inhibition's control module, ZigBee radio receiving transmitting module, signal amplification module, infrared induction module etc.
The RFID card reader adopts contactless Card Reader, continuous emitting radio frequency signal, and the RFID label adopts active label, receives radiofrequency signal and is then waken up and return corresponding information and give card reader.
Gate inhibition's control module adopts the 12V direct supply relay control gate magnetic of locking a door.
The ZigBee radio receiving transmitting module adopts the ZStack2007 wireless transmission protocol of TI company, realizes the point-to-point transmission and the MANET function of increasing income.The mutual networking of each acquisition node also can be used as routing node forwarding corresponding information, is transferred on the final coordinator node.All bottom layer node of coordinator node control, and implement final information and upper strata mutual.
The course of work is promptly by the label information in the RFID card reader induction respective range; As user during in the time of standing firm in front of the door about 1S; Controller is confirmed user's needs that open the door through infrared induction; Whether the automatic differentiation of RFID label information according to receiving opens the door, and the information of uploading is on coordinator node.
The beneficial effect of the utility model is:
1, this utility model with every Yishanmen as a node in the ZigBee wireless self-networking; Removed directly linking to each other of circuit between each node; Reduced difficulty of construction and to the destruction of body of wall, than traditional gate control system attractive in appearance more easy-to-use, and reduced the possibility of wiring error; Reduce the workload of debugging, reduced the cycle and the difficulty of engineering construction.And the damage of each node does not influence the operation of other nodes, has improved the stable degree of system, is convenient to installation and maintenance;
