Embodiment
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is described in more detail.
As shown in Figure 1, in the present invention, tunnel environment monitor and early warning system comprises following components: comprise radio sensing network 1, embedded gateway 2, built-in network control system 3, Tunnel testing center 4.
Whole system structure and function as described below: wireless sense network data acquisition node gathers tunnel environment information by the sensor self connected, node comprises terminal node 111, 112, 113, 121, 122, 123, 131, 132, 133, 141, 142, 143 and router node 11, 12, 13, 14, the environmental data information be collected adopts the Routing Protocol of minimum hop count to be sent to telegon through meromixis by each node, all to this region in a period of time again radio sensing network acquisition node of telegon collects environmental data and is sent to embedded gateway 2 by RS232 and is stored in SD card by the data collected, then the data received carried out overall fusion treatment and be sent to public network by 3G communication module.The data sending public network are carried out point-to-point communication acquisition by 3G communication module by built-in network control system 3, collecting environmental data information is stored in the database of built-in network control system 3, and built-in network control system 3 refreshes the environmental parameter entered in database at set intervals.Environment measuring personnel enter tunnel environment detection system by long-range PC monitoring terminal software or smart mobile phone client, by the data in calling data storehouse, just can carry out Real-Time Monitoring to tunnel environment.The watchdog routine of built-in network control system 3 constantly scanning can enter the environmental data of database in nearest one minute simultaneously, if there are data to exceed the threshold value of keeper's setting, be judged to be exception, the hummer 41 that then abnormal information is sent to remote detection center 4 by built-in network control system 3 sends alerting signal, thus realizes the function of early warning.
As shown in Figure 2, process flow diagram describes the method for coordinator node and radio sensing network data acquisition node (terminal node terminal node 111,112,113,121,122,123,131,132,133,141,142,143, router node 11,12,13,14) formation MESH network topology.In order to reduce data acquisition node power consumption, therefore coordinator node task is by accepting packet event-driven.Its step is as follows:
1. task enters waiting status, waits the generation of packet event to be subjected;
2., when receiving a wireless data packet, EOP (end of program) waiting status, enters executing state;
3. judge whether it is the packet that router node sends, if the packet that router node sends so performs step 4, otherwise enter step 8;
4. extract the hop count field in packet;
5. router node checks that whether the jumping figure of oneself distance coordinator node is still for empty, so performs step 6 if it is empty, otherwise enters step 7;
6. the hop count field in the packet of extraction is added the jumping figure that 1 becomes oneself, enter step 10;
7. the hop count field in the packet of extraction is added the jumping figure seen after 1 and whether be less than oneself distance coordinator node, so enter step 6 if be less than, otherwise enter step 10;
8. judge whether it is the packet that same network data acquisition node sends, if enter step 9, otherwise enter step 10;
9. data acquisition node data are carried out fusion treatment, enter step 10;
10. get back to the waiting status of task.
As shown in Figure 3, structural drawing depicts the data fusion between radio sensing network data acquisition node (router node, terminal node).
The present invention uses the distribution Kalman filtering information fusion with feedback, carries out data fusion to detected object.First carry out local Ka Er road side information to each data acquisition node to merge, then respective partial estimation result being sent adopts the Routing Protocol of minimum hop count to be sent to coordinator node, and the coordinator node radio sensing network acquisition node all to this region collects environmental data and be sent to embedded gateway 2 by RS232 and carry out overall fusion treatment.Owing to adding feedback element, make radio sensing network distinct device have duplex signaling contact, not only low layer fuse information is to high level transmission, and high layer information also participates in low-level nodes process, is provided with a kind of contact of interlayer between each acquisition node.Fusion accuracy can be made after fusion treatment higher than single-sensor precision, and the transmission quantity of data reduces greatly, thus reduce the transmission quantity of information, alleviate network conflict and congested.
As shown in Figure 5, process flow diagram describes built-in network control system 3 and identifies abnormal data and the method sending early warning signal comprises the steps:
1. the timer of built-in network control system 3 initialize internal;
2. whether timing was by ten minutes to check timer, if then enter step 3, otherwise entered not convenient for walking 5;
3. check the data in nearly ten minutes that store in built-in network control system 3 database, whether have data to exceed threshold value, if having data to exceed threshold value enter step 4, otherwise enter step 5;
4. abnormal information is sent to the hummer work at remote detection center 4 by built-in network control system 3, sends alerting signal;
5. timer reclocking.
The above, be only best mode for carrying out the invention, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses, and the simple change of the technical scheme that can obtain apparently or equivalence are replaced and all fallen within the scope of protection of the present invention.
