If the leg gusset that leaves does not link to each other with main controlled node 100a, the step of leaving just has some variations.With reference to figure 8.Network among Fig. 8 is the network that forms after the step of Fig. 6 is finished, now, leg gusset 100e will deviated from network, because it is to finish and the communicating by letter of main controlled node 100a by leg gusset 100c transfer, therefore its with leg gusset 100c between be connected and will in the end disconnect, promptly the link information that 100e is sent by leg gusset 100c is transmitted to after the main controlled node 100a, and being connected just between leg gusset 100c and the leg gusset 100e disconnects.
After the foundation of having finished network, the following describes as in electric appliance wireless control network of the present invention, sending or transmitting control command.
With reference to figure 9, it is the schematic flow sheet that sends or transmit an embodiment of control command in electric appliance wireless control network of the present invention.The structure of this electric appliance wireless control network is as follows:
Main controlled node 100f links to each other with leg gusset 100g, and leg gusset 100g links to each other with leg gusset 100h.
Main controlled node 100f is to leg gusset 100g sending controling instruction, because they directly link to each other, instruction can directly send to leg gusset 100g, leg gusset 100g returns confirmation after receiving instruction, afterwards, the processor among the leg gusset 100g judges that this instruction sends to leg gusset 100g, so according to its electrical equipment operating means of instruction manipulation, be sent completely after operation is finished and instruct to main controlled node 100f, main controlled node 100f returns confirmation after receiving instruction.
Main controlled node 100f is to leg gusset 100h sending controling instruction, because they directly do not link to each other, instruction cannot directly send to leg gusset 100h, and need leg gusset 100g to carry out transfer, leg gusset 100g judges that at first it is not a control command of issuing oneself after receiving instruction, but a forwarding instruction that is transmitted to 100h, leg gusset 100g returns confirmation earlier and represents that it receives that this forwardings instructs for main controlled node 100f.Afterwards, leg gusset 100g is transmitted to leg gusset 100h with this instruction, because this instruction is to be transmitted by leg gusset 100g now, so be expressed as in Fig. 9.Leg gusset 100h at first returns confirmation to leg gusset 100g after receiving this instruction, the processor of leg gusset 100h judges that this instruction sends to leg gusset 100h afterwards, so according to its electrical equipment operating means of instruction manipulation, be sent completely after operation is finished and instruct to leg gusset 100g, leg gusset 100g returns confirmation after receiving and finishing instruction.Leg gusset 100g has finished instruction to main controlled node 100f with finishing message announcement leg gusset 100h afterwards, and main controlled node 100f sends acknowledge message to leg gusset 100g.So far, main controlled node 100f finishes the control to leg gusset 100h.
In electric appliance wireless control network of the present invention, also include route priority in the network topology structure, when node is transmitted control information, select the route of forwarding according to route priority.This situation can take place when a node can have a plurality of communication path.Show in this case an embodiment with reference to Figure 10.
Network configuration shown in Figure 10 is as follows:
Main controlled node 100j links to each other with leg gusset 100l with leg gusset 100k, and leg gusset 100k links to each other with leg gusset 100m respectively again with leg gusset 100l, and leg gusset 100m is free of attachment to main controlled node 100j.When network is set up, leg gusset 100k is higher than the route priority of leg gusset 100l to leg gusset 100j to the route priority of leg gusset 100m, therefore,, can specify and use attached 100k to transmit during at main controlled node 100j sending controling instruction to leg gusset 100j.Concrete repeating process such as top shown in Figure 9, no longer repeat specification here.
For network with route priority, can in control command, add relevant routing iinformation by main controlled node, each node is transmitted and is got final product according to routing iinformation up to needs, do not need oneself to carry out Route Selection, in such cases, leg gusset can use the wireless control terminal of electrical appliance that does not have storage device shown in Figure 2.In another case, all leg gussets all are with the wireless control terminal of electrical appliance with storage device shown in Figure 1, at this moment, each leg gusset is all preserved by network topology structure and relevant route precedence information, so main controlled node can not comprise routing iinformation in control command, but judges use what routing forwarding by each leg gusset voluntarily according to the content of its preservation.
Route priority can be foundation in number of success with the information exchange of these leg gussets with main controlled node.Successful number of times is many more, and corresponding priority level is just big more, opposite, and successful number of times is few more, and priority is also just more little.
Route priority is directly related with topology of networks, when topology of networks changed, route priority also will change accordingly, and the variation of network topology structure may comprise following several situation: have new node to add, there is node to leave, has node to break down.Preceding two kinds of situations describe in front, last a kind of situation, there is node to break down, when main controlled node or leg gusset continuous several times send information or instruction and when not replying to another leg gusset, judge this leg gusset fault, situation about leaving according to this leg gusset is handled afterwards, and step and above-mentioned leg gusset leave similar.When network topology structure changed each time, main controlled node all can upgrade the network topology structure and the route priority of its preservation and send it to each leg gusset (if node has memory), guarantees the stable operation of whole network with this.
The situation of describing in conjunction with Fig. 9 and Figure 10 of in leg gusset sends or transmit the embodiment of instruction, only showing herein by small number of nodes, it should be appreciated by those skilled in the art, according to description herein, can predict fully when the node number expands to n, its operating procedure is similar.
