The technique effect of the application：Intelligence switching wire communication and radio communication, improve distributed air conditioner overall communication
Quality, efficiency and reliability.
As shown in fig.1, in the embodiment of the present invention, ZigBee module is mounted with air-conditioner set, so as to make air conditioner
Group is provided with radio communication function.So-called ZigBee module has the characteristic similar to mobile base station, it is possible to achieve wireless network
Self-organizing, self-healing etc. function, and the mutual radio communication of air-conditioner set can be realized within the specific limits.
Meanwhile as shown in figure 1, also arrange some ZigBee modules in bus, make bus and each air-conditioner set it
Between can also use communication connect, and be between each ZigBee module arranged in bus by bus realize have
Line communicates.After air-conditioner set is connected with the ZigBee module in bus, bus can be accessed, so as to by wired mode with
Other air-conditioner sets communicate, it is also possible to pass through wired mode and the general packet radio service technology (General of distal end
Packet Radio Service, GPRS) it is GPRS module communication (needing by GPRS/ZigBee module protocols converter),
And (needed by wired mode and the building management system of distal end (Building Management System, BMS) communication
By RS485/ZigBee module protocols converter).
In the specific implementation, as shown in figure 1, the arrangement of the air-conditioner set of wireless transmission layer can be laid out according to specific engineering
(e.g., figure mounting arrangements, the ZigBee module in wire transmission layer are likely to occur the place installation of communication quality difference in some predictions
Air-conditioner set needs to be in communication with each other, but has physical isolation, if any wall), then, ZigBee module is connected with a bus
Come.The apolegamy equipment as bus such as GPRS/Zigbee protocol converters, RS485/Zigbee protocol converters.Traditional is total
Line only has a channel, and its channel capacity and channel speed are limited, can fall over each other to send information and lead due to each equipment room unavoidably
Cause conflict, but bus possesses the characteristics of transmission quality is good, stability is high with respect to having for communication.
Based on said system framework, as shown in fig.2, the idiographic flow to be communicated between realizing air-conditioner set is as follows：
Step 200：Source air-conditioner set can detect to the quality of wireless channel between local and purpose air-conditioner set.
Step 210：Source air-conditioner set judges whether above-mentioned quality of wireless channel reaches preset standard according to testing result, if
It is then to perform step 220；Otherwise, step 230 is performed.
Specifically, in the embodiment of the present invention, when performing step 210, source air-conditioner set can be used but is not limited to following
Method：
First, source air-conditioner set sends broadcast message to periphery, and the mark of purpose air-conditioner set is carried in broadcast message,
Broadcast message is sent to purpose air-conditioner set by other air-conditioner sets.
Then, source air-conditioner set can receive at least one feedback information for coming from purpose air-conditioner set, wherein, one is anti-
The current duration of the paths between source air-conditioner set and purpose air-conditioner set, and described one are at least carried in feedforward information
On paths by way of other each air-conditioner sets mark.
Because broadcast message can reach purpose air-conditioner set via different other air-conditioner sets, and often by one other
Air-conditioner set, will carry in broadcast message by way of other air-conditioner sets information, so, purpose air-conditioner set often receives
To a broadcast message, the path for receiving this broadcast message can be known, i.e. this broadcast message is it by which
His air-conditioner set is sent to purpose air-conditioner set from source air-conditioner set.Therefore, purpose air conditioner often receives a broadcast message,
The description information of (the original route return) of respective paths will be returned to source air-conditioner set.
Finally, source air-conditioner set is picked out current duration shortest path, judged according at least one feedback information of acquisition
The current duration of above-mentioned current duration shortest path, if current duration maximum no more than history, if, it is determined that wireless channel
Quality reaches preset standard, i.e. wireless communication status is good, can select above-mentioned current duration shortest path as source air conditioner
Communication path between group and purpose air-conditioner set, otherwise, it determines quality of wireless channel is not up to preset standard, i.e. radio communication
Situation is poor, it is necessary to switch to wired communication mode.
Step 220：Source air-conditioner set determines that quality of wireless channel reaches preset standard, then using communication and mesh
Air-conditioner set carry out data transmission.
For example, as shown in fig.1, the air-conditioner set 1 (abbreviation air-conditioner set 1, similarly hereinafter) for being mounted with ZigBee module is source
Air-conditioner set, and it is mounted with that the air-conditioner set 6 (abbreviation air-conditioner set 6, similarly hereinafter) of ZigBee module is purpose air-conditioner set, that
, reach the Collaborative Control between unit by communication between the two.
In the present embodiment, due to being respectively mounted ZigBee module, therefore it can be route each other between air-conditioner set, i.e. air-conditioning
Unit 2, air-conditioner set 3, air-conditioner set 5 etc. can forward data as the router of air-conditioner set 1.
As shown in fig.3, assuming in this quality of wireless channel measurement process, air-conditioner set 1 obtains a routing table,
The path that air-conditioner set 1 reaches air-conditioner set 6 is have recorded in the routing table following three：
Path 1：Air-conditioner set 1->Air-conditioner set 5->Air-conditioner set 6；
As shown in figure 3, the current duration (also referred to as path length) in path 1 is：5s+1s=6s；
Path 2：Air-conditioner set 1->Air-conditioner set 2->Air-conditioner set 6；
As shown in figure 3, path 2 it is current when it is a length of：4s+7s=11s；
Path 3：Air-conditioner set 1->Air-conditioner set 3->Air-conditioner set m->Air-conditioner set 6；
As shown in figure 3, path 3 it is current when it is a length of：3s+4s+3s=10s.
So, by calculating, air-conditioner set 1 judges that current duration shortest path is path 1：Air-conditioner set 1->Air conditioner
Group 5->Air-conditioner set 6, a length of 6s when it is current, less than the most long current duration (being assumed to be 10s) of history, then, road can be chosen
Footpath 1 carries out data transmission between air-conditioner set 1 and air-conditioner set 6.
Step 230：Source air-conditioner set determines that quality of wireless channel is not up to preset standard, then wirelessly with it is preset
Bus connection, carried out data transmission by above-mentioned bus using wired communication mode with purpose air-conditioner set.
For example, referring still to shown in Fig. 1, can also be reached between air-conditioner set 1 and air-conditioner set 6 by wired communication mode
Collaborative Control between unit.
As shown in figure 1, if the channel conditions between air-conditioner set 1 and air-conditioner set 6 are poor, the meeting of air-conditioner set 1 exists
In ZigBee module in bus, select the most strong ZigBee module 1 of signal between air-conditioner set 1, by data first via
Communication is sent to ZigBee module 1, then via cable network (i.e. bus), is transferred data to and air-conditioner set 6
Between the most strong ZigBee module 3 of signal, then data are transmitted to by air-conditioning by communication by ZigBee module 3
Unit 6.
Certainly, if air-conditioner set 1 needs to send data to remote monitoring via GPRS, or, send to BMS, then
Same way can be used, i.e., in each ZigBee module of the meeting of air-conditioner set 1 in bus, between selection and air-conditioner set 1
The most strong ZigBee module 1 of signal, data are first sent to ZigBee module 1 via communication, then is passed through
ZigBee module 1, data are directly sent to remote monitoring by bus via GPRS；Or/and air-conditioner set 1 can be in bus
On each ZigBee module in, select the most strong ZigBee module 1 of signal between air-conditioner set 1, by data first via
Communication is sent to ZigBee module 1, then by ZigBee module 1, data are sent directly into BMS by bus.
In the embodiment of the present invention, ZigBee module, routing function is not had, it functions as wire transmission layer and nothing
The Coupling device of line transport layer, realize GPRS/Zigbee protocol converters, RS485/Zigbee protocol converters, air conditioner
Signal transmitting and receiving between group.

Table, have recorded respectively in each routing table data transmit-receive path between ZigBee module and GPRS/Zigbee protocol converters,
Data transmit-receive path between ZigBee module and RS485/Zigbee protocol converters, GPRS/Zigbee protocol converters with
Data transmit-receive path between air-conditioner set, the data transmit-receive road between RS485/Zigbee protocol converters and air-conditioner set
Footpath；I.e. GPRS/Zigbee protocol converters, RS485/Zigbee protocol converters and air-conditioner set have which is selected respectively
ZigBee module via wired layer data transmit-receive path.
The generating process of routing table of the generating process of above-mentioned each routing table with being introduced in step 220 is similar, herein not
