A concrete example of distributed geology disaster monitoring collection transmission instrument of the present utility model: main process equipment is with the system core part of 32 arm processor LPC2119, wireless radio frequency modules ZG-Link1281 and GPRS module SIM300-C composition host device; ZG-Link1281 is responsible for receiving the data of collection in worksite, and SIM300-C sends to background server by the 2G mobile network with data and/or the warning message of gathering; Wireless sensor node is with 8 AVR processor MEGAL1281, radio frequency chip 86RF212 combined joint core, and 86RF212 is responsible for sending to main process equipment the data of collection in worksite; Every main process equipment can connect 30 wireless sensor nodes, each wireless sensor node can connect 2 kinds of sensors, main process equipment can connect the sensor of 1 tunnel output switching value signal, active devices is judged according to the data of gathering, if the data value corresponding of gathering surpasses the alarm threshold value of setting, then main process equipment can be transferred to background server with warning message by the 2G mobile network, to report to the police accordingly.
The concrete principle of work of distributed geology disaster monitoring collection transmission instrument of the present utility model is: the long-range parameters that arranges at the background server place at first can dynamically arrange alarm threshold value in the main process equipment according to field condition at the background server place; The main frame of distributed geology disaster monitoring collection transmission instrument is laid near the geologic hazard body safe part, the wireless sensor node of front end connects various sensors, be laid in the geologic hazard body everywhere according to designing requirement, with at least a parameter in the displacement, rainfall, earthquake sounds, degree of tilt, water level of monitoring measured point; If there is the 220V alternating current at the scene, then can connect an AC-DC module, be the main process equipment power supply; If the scene does not have alternating current, then can main process equipment be connected with storage battery by two core connection terminals, for main process equipment provides electric power; If the on-the-spot storage battery inconvenience of changing then can connect solar panels in order to be the storage battery charging at storage battery; When the instrument operate as normal is transmitted in distributed geology disaster monitoring collection, various signals according to the setting timing acquiring front end sensors of background server, transmit back background server by the 2G mobile network, if the change amount signal that front end sensors is gathered is greater than predefined alarm threshold, then main process equipment transmits back the background server platform with alerting signal, and the software of background server operation carries out corresponding analyzing and processing according to predefined scheme to the data of passing back.
Wherein, for wireless sensor node, because it is generally more dangerously steep to carry out the environment of geologic hazard monitoring, if it is unrealistic to change the battery of wireless sensor node frequently, the energy consumption of wireless sensor node considers just to be placed in primary position, and whole design of the present utility model all launches round this central point.
In the specific implementation process, the core routing algorithm of the wireless sensor system of being made up of all wireless sensor nodes and main process equipment is with reference to the ZigBee standard, and the ZigBee standard is supported three kinds of network topology structures, i.e. radial network, mesh network and bunch tree network.On the basis of the network topology structure of bunch tree network, the parameters such as signal intensity of the route degree of depth of reference mode, admissible neighbor node number and neighbor node are selected best routed path; This algorithm is mainly realized by each node direct control register.The utility model has adopted father and son's node in the network of bunch tree network and the routing table design concept of mesh network, base-station node (main process equipment) belongs to telegon, wireless sensor node belongs to router, each node has unique 16 fixing short addresses, the routing table of each node can be held 30 neighbor nodes, and the route degree of depth of whole network can arrive 8 grades.
In above-mentioned wireless sensor system, the main effect of base-station node is to set up a network, accept wireless sensor node and add network, receive data, deal with data that wireless sensor node sends, and data is sent to the background server of Surveillance center by the GPRS module.Because base-station node will move the parallel task more than 2, used μ C/OS-II embedded OS at bottom, ZigBee task and GPRS task have been set up after the start, just set up a network behind the ZigBee task initialization and enter and monitor and waiting status, receive the affirmation message that comprises clock time after the networking request of sensor node to its transmission, connect, wait for and receive data, data are handed to the GPRS task to data after receiving successfully, simultaneously up-to-date clock time are returned to the sender; Connect Surveillance center by given IP address behind the GPRS task initialization, timed sending after the successful connection " heartbeat " packet is to keep data link, after the data that receive the forwarding of ZigBee task, send it to the background server of Surveillance center immediately, handled accordingly by the background server of Surveillance center.Above-mentioned base-station node has played the effect of network coordinator, needs to continue monitor network, so be in normal mode of operation always.
And the effect of wireless sensor node be according to the time that the background server of Surveillance center is set regularly be waken up, add network, image data, accept other node the networking request, transmit data etc.
For consideration energy-conservation and the minimizing network complexity, each wireless sensor node all has sleep and routing function, after wireless sensor node to be networked powers on, can at first send broadcasting, near being used for seeking wireless sensor node, if current have wireless sensor node to link network, then reply the packet that comprises clock time, route progression, signal intensity; This treats that network access node will arrange the length of one's sleep according to the time of answer and selected routed path is gone forward side by side into sleep; If do not reply (near wireless sensor node does not network or networked but is in sleep state), this wireless sensor node to be added only keeps wireless radio frequency modules and is in work; After waking up, carries out near the wireless sensor node of networking the operation of gathering and sending data to base-station node; If data send and successfully all can send near the wireless sensor node whether packet that comprises clock time, route progression, signal intensity remain to be networked inquiring and exist, can therefrom select an optimum node according to the routing mechanism of setting after the wireless sensor node to be networked that is in listening state is received, and enter sleep and wake up on time according to the content of packet.
