Cable ditch monitoring subsystem and intelligent entrance guard subsystem collecting data information；
S3: the collected information of institute is sent to ZigBee coordinator node by ZigBee wireless network in a multi-hop fashion, most
ZigBee coordinator node is given these information to local monitor center by serial ports afterwards；
S4: local monitor center sends information to remote server by fiber optic network.
Specifically, ZigBee-network unit is divided into full-function device and reduced function device, ZigBee association using equipment
It adjusts device and router to belong to full-function device, supports the institute of IEEE802.15.4 functional, terminal device belongs to thin device, only
Support IEEE802.15.4 part of functions；
ZigBee coordinator: the equipment is responsible for creating ZigBee wireless network and personal area network ID and the selection of this wireless network is arranged
The communication channel in one space, it is seen that coordinator node is the core of ZigBee wireless network, when coordinator node builds network
After standing successfully, functionally, coordinator node will be changed into router node；
Router: the function of the equipment is similar with the router in daily life, is mainly responsible for the coverage area for expanding network, leads to
Cross the mode of multi-hop, the information in transmission network；
Terminal device: the equipment is mainly responsible for the acquisition of data, and does not have the data forwarding function of routing node, usually with biography
Sensor is connected, and the most of the time in a dormant state, powers, to reduce cost usually using battery；
After ZigBee node powers on, judging first oneself is coordinator, router or terminal device:
Scan channel is carried out if it is coordinator, after being initialized and then establishes network, enters finally into network monitoring state,
When data is received, take-up judge whether be other nodes networking application, if it is network apply, judge whether available free
Address, available free address just distributes 16 short addresses, and no free address is returned to listening state, if not the application that networks,
Then enter data processing function, is returned after the completion of processing；
If it is router, scan channel is executed after the completion of initialization, then sends the request that networks, enters network after networking successfully
Listening state enters data processing function when receiving data, returns after the completion of processing；
If it is terminal device, scan channel is executed after the completion of initialization, then sends the request that networks, entered after networking successfully and stop
Dormancy state enters data processing function when receiving data, returns after the completion of processing.
