Fig. 4 is the method flow diagram of the large-scale storage tank security protection monitoring system based on wireless sensor network of the present utility model, and concrete steps are as follows:
Step 1: first when downloading, be numbered with unique No. ID to each node, node comprises general sensor nodes, leader cluster node, via node, aggregation node;
Step 2: by ad-hoc location on node installation to storage tank, for periodically gathering environmental data and detecting infrared invasion signal;
Step 3: opened nodes switch, all nodes outside aggregation node work on power and are intercepting state;
Step 4: operating personnel control aggregation node and start working, aggregation node synchronizing signal of going on the air completes the time synchronized of one-level bunch; Bunch head of the child node of one-level bunch and secondary bunch complete synchronous after, be switched to the channel of respective secondary bunch and broadcast synchronization signal to complete the synchronous of secondary bunch;
Step 5: not completing synchronous node, to carry out the deadline by the confirmation signal of the periodic signal or bunch head that continue to intercept adjacent node synchronous;
Step 6: node first judges whether to need to adjust time slot, if desired, then by the adjustment amount calibration operation time slot that bunch head provides according to bunch head being taken turns the confirmation signal sent to it;
Step 7: the cycle data that sensor node will gather, history warning message, energy information is sent to a bunch head;
Step 8: bunch head replys sensor node confirmation signal, if sensor node does not receive the confirmation signal, will resend, sends 3 times at most;
Step 9: after the periodic signal time slot of each node terminates, have one section of burst time slot.At this moment in gap, each sensor node is all operated in listening state.
Step 10: leader cluster node merges this cluster data or directly or send it to aggregation node by via node;

Step 12: if control centre stops network work, transmission quits work order by aggregation node, otherwise sensor network works on.
Fig. 5 is the schematic diagram that between the utility model bunch, FDMA is multiplexing.With based on bunch Hierarchical network topological structure corresponding, the utility model adopt based on bunch network frequency division mechanism.Shown in Fig. 5 is a channel allocation situation with the two-tier network of m bunch, the channel allocation of whole system was undertaken by two stages: 1) in system initialisation phase, at system aggregation node, under the management of at different levels bunches of heads, the classification realizing network is synchronous, frequency division strategy adopts the strategy that classification is benchmark with bunch head, at one-level bunch synchronous phase, all leader cluster nodes are in the channel of aggregation node, receive the synchronizing signal from aggregation node, complete the synchronous of one-level bunch, at secondary bunch synchronous phase, bunch head is respectively by the channel of channel switch to this bunch, to a bunch interior nodes broadcasts synchronization messages, realize the synchronous of secondary bunch, one is had to the network of n level bunch, by that analogy, 2) in the system works stage, leader cluster node is by channel switch (this bunch of channel and higher level's bunch channel), and the message realized between at different levels bunches is communicated with.
Fig. 6 is the self calibration synchronization policy flow chart that the utility model is benchmark with bunch head.The self calibration strategy being benchmark with bunch head mainly solves the overlapping problem of time slot that the factors such as clock drift cause, and basic thought is: with the clock of bunch head for benchmark, and adjustment bunch interior nodes is with the timing differential of bunch head in real time, to reach the object of relative synchronization.Concrete implementation method is as follows:
A step 1: leader cluster node is that in system, each sensor node safeguards that is expected a working time slot;
Step 2: in bunch, each sensor node safeguards an actual working time slot respectively;
Step 3: bunch inner sensor node when sending cyclical signal bag to leader cluster node, by the markers of delivery time incidentally issue leader cluster node;
Step 4: leader cluster node is when receiving the cyclical signal bag of sensor node, the markers that record is local, by the markers of more local markers with the sensor node received, with bunch head clock for benchmark, judge the clock jitter of sensor node, in the confirmation bag returning to sensor node, give the adjustment amount of output time slot;
Step 5: sensor node does not adjust working time slot after receiving the time slot adjustment amount of bunch head immediately, but adjusts working time slot in the next round sampling period.
Fig. 7 is clock drift fault-tolerant strategy schematic diagram of the present utility model.Above synchronous method of the present utility model is a kind of rear synchronous method; just adjust after deviation occurs; it is a kind of droop control; in order to prevent the conflict of burst and periodic signal completely; the utility model have employed drift fault-tolerant strategy as shown in Figure 7; by adding guard time to realize between periodic signal access-hours and burst access-hours; its shortcoming have lost certain burst response time; advantage makes system have certain fault-tolerant ability to clock drift, decreases data collision.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection range of the present utility model.
