In field of computer technology, each node (including Centroid and terminal node) can in communication process
With allocated hardware address, usually 16 system, assigning process is generally completed by the node on system top.In prior art
Generally use the hardware address of level encoder pattern distribution node, i.e. in system all addresss of node all an address pool
In, in pond, all addresses are not repeated；It is low to there is address utilization rate in this pattern, and the number of addresses of needs is big, available address number
Measure the problems such as limited, directly all node address are encoded by server in addition, a large amount of calculation resources can be consumed.The application uses
The mode of two-level address coding, shares two levels by coding load, cloud server at the first address layer to relative number
Measuring less Centroid encoding physical addresses, the terminal node that its subordinate is connected at the second address layer by Centroid is physically
Location encodes, the operational capability of cloud server is concentrated on Centroid less with relative populations mutual on, fill again simultaneously
Divide the operational capability that make use of Centroid, balance the load of whole system；Additionally, as a example by sixteen-bit system, single-level address
Coding is only provided that 2^16=65535 physical address, and two-level address encodes because introducing the second address layer so that each ground

The form of packet, sets up dialogue with destination node.As shown in Figure 1, cloud server 101 is intended to access a terminal node 103,
Need first to access on it and belong to the Centroid 102 connected, therefore the application designs communication data packet and carries two-level address, take
Band target's center node physical address and target terminal node physical address, communication data packet only need to be sent out by cloud server 101
Give the less Centroid of relative populations 102, it is to avoid under single-level address coding situation, cloud server needs to save to the whole network
Point broadcast data packet, decreases system resources consumption.Communication data packet also carries control information in addition, comprises cloud service
The operation that destination node to be performed by device.
Centroid 102 receives the communication data packet that cloud server is sent, it is judged that the target carried in communication data packet
Centroid physical address is the most consistent with the physical address of self, as this communication data packet of inconsistent explanation is not intended for this section
Point, abandons；As unanimously then received this communication data packet, analytic message, obtain the target terminal node thing that next stage needs to forward
Reason address, and the content of the information of control.
Terminal node 103 receives Centroid and forwards the communication data packet of coming, it is judged that the target carried in communication data packet
Terminal node physical address is the most consistent with the physical address of self, as this communication data packet of inconsistent explanation is not intended for this section
Point, abandons；As unanimously then received this communication data packet, analytic message, obtain the content of control information, perform control information, and
Response results is returned to the upper Centroid 102 belonging to and connecting.Centroid 102 receives the response results of target terminal node
After, transmitted response result is to cloud server 101.

A kind of data structure in calculation machine field, multiway tree.In figure 3, with a subset of multiway tree, the form of binary tree is (i.e. only
Enumerating limited branch road, the situation of other branch roads is all equal to the branch road enumerated) two-level address coding in the application is described
One embodiment of mode.Other subset forms in system structure, all can refer to the description of the present embodiment.
Two-level address coding by the way of address multiplex, can also further expand the scope of available physical address.
Direct report is connected to the Centroid 1 of cloud server 101, the physical address of Centroid 2 is configured to not
Identical (if there being address to repeat, then can cause the conflict of information forward-path in this level)；Terminal node 1, terminal node 2
Subordinate is connected to Centroid 1, and terminal node 3 subordinate is connected to Centroid 2, similar, in this level, terminal node
1, the physical address of terminal node 2 is configured to differ that (they have identical upper layer node, if there being address to repeat, then can
This level causes the conflict of information forward-path), but terminal node 1 and terminal node 3 or terminal node 2 and terminal
The physical address of node 3 then can be configured to identical, because they have different upper layer node physical address, whole information
Forward-path also differs.In sum, direct report differs, often in the different Centroid coded addresses of cloud server
Individual Centroid subordinate connects terminal node physical address and differs, the terminal node address of different Centroid subordinaties identical or
Differ.By two-level address coded system, it is achieved that the multiplexing to limited physical address, reduce the application to physically

Up-downgoing message between Downlink Control Information and up response message in flow process, or difference different dialogue flow process.High in the clouds takes
Business device sends after certain downbound request sends, as received corresponding up response, cloud server 101 the most in the given time
Then this bag sequence number is made marks, and from task queue, removes the process that this bag sequence number represents, hang up this process in depositor,
Then proceed to process process follow-up in task queue.Cloud server 101, when receiving aforementioned up response, is looked into by labelling
Find the process being in suspended state, reload and process queue to task, recover the process to this conversation process.Pass through Bao Xu
Number mechanism, it is ensured that high in the clouds processor 101 is in the state of parallel processing task all the time, meet batch data communication
Need, it is to avoid because the response of a certain conversation process not in time or hangs the process resources idle causing high in the clouds processor 101, shadow
The execution efficiency of acoustic system.

Point executive control operation, such as, inquire about the state of terminal node, control the state of terminal node.Apply specific to irrigation and water conservancy,
Can be presented as that inquiry terminal irrigates the state of valve, cell voltage, valve pressure, device temperature, the soil moisture, soil is wet
Degree, integrated flow, it is also possible to be presented as that controlling terminal irrigates opening or closing of valve.After message performs, Centroid will receive
Response message be back to cloud server, complete conversation process.In conversation process, the application also introduces and wakes up up and time-out
After the conversation process of retransmission mechanism, cloud server and terminal node is set up, such as terminal node the most in the given time to center
Node response cloud server send task requests, then Centroid activate Retransmission timeout mechanism, to terminal node again or
Transmission request repeatedly, to guarantee that terminal node does not fail to normally receive request because of external factor interference, adds this
The reliability of application.As received the response of terminal node, then centromere after Centroid repeat requests the most in the given time
Point activation wakes up mechanism up, sends wake request to terminal node, the wake request such as terminal node normal response, it was demonstrated that terminal saves
Point does not receives task requests because being in holding state, and now terminal node is activated as normal operating conditions, and Centroid is again
Secondary transmission task requests, the request of terminal node normal response, response results is back to cloud server by Centroid, and it is right to complete
Words flow process；As terminal node fails normal response wake request, it was demonstrated that terminal node is in abnormal operating state, Centroid
The then terminal node of this abnormal condition of labelling, is back to cloud server by labelling result, terminates conversation process.So increase
