As shown in Figure 4, first multi-online air-conditioning system carries out networking, the hierarchical structure in constructing system,
Indoor set is as the common ancestor node of indoor sets all in system, and each indoor set is all as off-premises station
Descendant nodes, there is his father's node device in each indoor set, this father node equipment can be off-premises station,
It can also be another indoor set.Each equipment must be communicated by its node relationships, with indoor set
As a example by 13#, 13# communicates with outer machine, need to sequentially pass through 13# → 7# → 3# → outer machine.
Said method, is by checking that the signal transmission power of self is sent to its father node and sets by object
Standby, his father's node device detects its signal and receives power, will include the signal transmission power of detection object

Giving during processing object, detection data no longer change, only transmitting procedure.
As shown in Fig. 4, Fig. 5, Fig. 6, interior machine wireless module 1#-17# is regular according to wireless networking communications,
Wireless network tree topology is jointly generated with outer machine wireless module.Communication rule in tree topology
Then: node can only directly and its father node and the child node communication of oneself；Message is from one
When node is sent to another node, message must be moved upwards up to nearest public from source node along tree
Ancestors, move down arrival destination node further along tree.Such as, outer machine communicates with 12#, be along outward
The path of machine--1#--5#--12# is carried out.Outer machine wireless module is a coordinator, is unique public ancestral
First, play the effect of network construction and control, store the routing iinformation of whole network, including direct son
Node and the Sun Jiedian of each direct descendent.
During networking, due to the interference of site environment, two internodal communication qualities can be reduced,

Interior machine is issued in the communication protocol data of outer machine, increases signal transmission power TxPw and signal receives
Two data of power RxPw, it is possible to use mw or dBm represents.
(2) father node fills in signal power data
Interior machine wireless module, when issuing outer machine data, fills in the signal transmission power TxPw of oneself.On
The signal this interior machine being detected, when receiving these interior machine data, is received power RxPw by the father node of a layer
Being filled in communication data, so far TxPw and RxPw data have been filled in completely the most.Then proceed to up
Layer transmission, but TxPw and RxPw data retain constant always, until outer machine.

Reception power be all RxPwi.
Radio communication quality detection device and outer machine foundation wirelessly or non-wirelessly communicates, outer machine by RxPwi,
TxPwi, Ni, N pass to communication quality detection device.
(4) signal transmission power weight is arranged
Radio communication quality detection device can arrange interior weight corresponding for machine signal transmission power TxPwi
Qi.Launch power TxPwi the least, represent that it, under the least power, just can meet the normal of internal-external machine
Communication, the Communication Jamming source in the middle of this is fewer, and communication quality is more satisfactory, the weight therefore set
Qi will be more greatly.Reference table 1.
(5) calculate and show the communication quality of each interior machine
After elapsed time section T, internal-external machine has carried out N and has taken turns radio communication.Within (j is that interior machine is compiled as a example by machine j
Number), in N takes turns, when having Ni use TxPwi power to send, father node detects and issues outer machine
Reception power be all RxPwi, the weight that another TxPwi power is corresponding is Qi, then the communication of this interior machine
Quality calculation formula is:
Radio communication quality detection device, according to above-mentioned formula, can be calculated and be shown the communication of each interior machine
Quality.
(6) judge whether to increase repeater and the number of repeater and position
Set communication quality threshold M ', weigh current internal-external machine communication conditions with it the most normal.
Work as Mj > M ', show that this interior machine current communicates normally with outer machine, otherwise need near this interior machine
Increase wireless repeater.The position of wireless repeater can affect the degree of information enhancement, needs to select properly
Position meet Mj > M '.If communication quality is very poor, it may be necessary to multiple repeaters remain normal
Internal-external machine communication.
