Make, since minimum level-one sensor node, the data of collection are transmitted to father node, the data and son that father node oneself will be collected
The father node of oneself is transmitted to after the data aggregate that node transmits again, aggregated data is finally transferred to cluster head；
Wherein, father node is to be known as father node according to the node of the transmission direction of data convergence data in minimum spanning tree, will
The node that data are transferred to father node is child node；
Step 8: the calculating of cluster head weights：After the completion of step 3 sub-clustering, cluster head obtains the position of entire cluster interior nodes, section
Point dump energy and sensor node may monitor to obtain the size information of data, wherein Ecir=E1r+E2r+…+EirIndicate whole
The residual energy magnitude of a cluster, KciIndicate the size of data of cluster head polymerization, DijThe distance between adjacent cluster head is indicated, to adjacent two cluster
Weights are calculated between head i, j, and the formula of weights is defined as：
Wij=b1(Ecir+Ecjr)+b2Dij+b3(Kci+Kcj)
Wherein, EcjrAnd KcjThe size of data of the residual energy magnitude and cluster head j polymerizations of cluster head j, and b are indicated respectively1+b2+b3=1,
System is according to system to Ecir、DijOr KciIt is required that proportion difference adjust biValue and obtain the weights for meeting different needs；
Step 9: leader cluster node constitutes simple graph model：Each cluster head is regarded to a vertex of figure, side is used between adjacent cluster head
It is connected, the weights of each edge are obtained by the weight computing formula in step 8；
Step 10: leader cluster node builds minimum spanning tree：After the simple graph model be made of the leader cluster node that step 8 provides, root
Minimum spanning tree is built according to the definition of Prim minimal spanning tree algorithms；
Step 11: cluster head data aggregate：After the minimum spanning tree construction complete of leader cluster node, since minimum level-one cluster head,
The data of collection are transmitted to father node, father node will be again transmitted to after data aggregate that the data that oneself polymerize and child node transmit from
Oneself father node, is finally transferred to base station by aggregated data；
Step 12: balanced node energy consumption：For the consumption of balance nodes energy, the too fast death of node is prevented, maintains cluster normal
Operation, after often carrying out M wheels, the step of just reselecting cluster head, then re-start front, wherein the energy consumption of node can be by
LEACH energy consumption models are estimated；
Step 13: the maintenance of cluster：After cluster interior nodes death, it is possible to the minimum spanning tree path failure in cluster, institute can be caused
With before node is by death, node sends a Die information to cluster head, indicates that oneself i.e. will be dead, cluster head receives this letter
After breath, cluster head begins to rebuild minimum spanning tree to cluster interior nodes；
Wireless communication module is connect with central control module, is wirelessly connected with computer and intelligent sliding moved end, for controlling center
The control information operation of molding block is sent to computer and intelligent sliding moved end by wireless；Realize remote-control operation；
The wireless communication module multiple gateway terminal fast roaming method MAP node general data packets kidnap the specific of forwarding mechanism
Steps are as follows：
Step 1, after MAP nodes receive unicast packet, the source addresses mac of data packet, then inquire local translation table at extraction
The source addresses mac are judged whether in table, and in local translation table, then explanation is the data of the client transmission of this node connection
Packet, enters step two；Otherwise, node is only forwarding the data packet, without processing；
Step 2 extracts the mark in local translation table after source mac address searches to corresponding local translation table entry
Domain flags carries out step-by-step ＆ operations with L2P_NCL_CLIENT_WIFI, and result 1 then illustrates that data packet is sent out by wifi clients
Go out, enters step three；Otherwise, without processing；
Step 3 extracts the IP layers head of data packet, then obtains purpose IP address, and destination IP is 10 or 192 network segments, then
Illustrate that data packet is destined in net, without processing；Otherwise four are entered step；
Step 4 obtains the addresses mac of MPP selected by current MAP nodes, is compared with the addresses packet rs destination mac, identical,
Then illustrate that data packet is destined for MPP nodes selected by current MAP, without any processing；Difference, then by the purpose of data packet
The addresses mac are modified as the addresses mac of MPP nodes selected by current MAP nodes, enter step five；
Step 5, after the addresses packet rs destination mac are changed, according to the new best next-hop node of purpose mac address searches, so
The unicast data packet header of L2P protocol definitions is added afterwards and l2p_transmit_skb_to_initi functions is called to be sent to MAP sections
The selected MPP nodes of point are gone, and are forwarded by the MPP nodes；
Module is perfused, is connect with central control module, for carrying out material perfusion operation to filling cavity；
Negative pressure module, connect with central control module, and negative-pressure operation is carried out for passing through peristaltic pump；
Alarm module is connect with central control module, for passing through alarm to detection data progress and alarm extremely；
Recycling module is connect with central control module, is recycled to used raw material for passing through returnable bottle.
2. the control system in multi-direction organizational project porous material perfusion as described in claim 1, which is characterized in that the nothing
Line communication module method for transmitting signals is as follows：
First, original signal is obtained；
Secondly, diagonally opposing corner matrix can be changed according to the weight that terminal usage quantity is determined, original signal is encoded, is waited for
Transmit encoded signal；
Then, encoded signal to be transmitted is transmitted by destination channel to signal receiving end；
Finally, using according to the descrambling matrix determined with the relevant acquisition of information situation of destination channel, signal receiving end is connect
The signal received carries out scramble process.
