As shown in figure 3, a kind of detection method of communication quality is disclosed, for as between detection object and process object
The equipment (such as indoor unit or outdoor unit) of data transfer is carried out, including:
S31, the detection data that the detection object is sent under different moments is obtained;Wherein, each detection data
In include the signal transmission power inscribed at this of detection object;
S32, when receiving the detection data, to it is described detection object signal reception power be detected, determine
It is described detection object at the time of sending the detection data under signal reception power;
S33, by include the signal transmission power and signal reception power detection data be sent to it is described processing pair
As.
As shown in figure 4, multi-online air-conditioning system carries out networking, the hierarchical structure in structure system, indoor unit conduct first
The common ancestor node of all indoor units in system, each indoor unit is as the descendant nodes of outdoor unit, each indoor unit
All there is his father's node device, which can be outdoor unit, can also be another indoor unit.Each equipment is necessary
Communicated by its node relationships, by taking indoor unit 13# as an example, 13# is communicated with outer machine, need to pass through successively 13# → 7# →
3# → outer machine.
The above method is that the signal transmission power of itself is sent to his father's node device, Qi Fujie by check object
Point device detects its signal reception power, will include the testing number of the signal transmission power and signal reception power that detect object
It is dealt with objects according to being sent to, wherein during detection data is sent to process object by father node, detection data no longer becomes
It moves, only transmission process.
As shown in Fig. 4, Fig. 5, Fig. 6, interior machine wireless module 1#-17# is according to wireless networking communications rule, with the wireless mould of outer machine
Block generates wireless network tree topology jointly.Rule of communication in tree topology is:One node can only directly with
Its father node and the child node of oneself communicate;When message is sent to another node from a node, message must be saved from source
Point is moved upwards up to nearest public ancestors along tree, and arrival destination node is moved down further along tree.For example, outer machine and 12#
Communication, be along outer machine -- and the path of 1#--5#--12# carries out.Outer machine wireless module is a coordinator, is unique public
Ancestors play the effect of network construction and control, store the routing iinformation of whole network, including direct descendent and it is each directly
The Sun Jiedian of child node.
During networking, due to the interference of site environment, the communication quality between two nodes can be reduced, cause interior machine with
Outer machine does not communicate or second-rate, at this moment just needs to increase wireless repeater near this interior machine, it is strong to increase wireless signal
Degree.
Radio communication quality detection device includes mainly power module, communication module, computing module and display module.Power supply
Module provides power supply for detection device, and communication module establishes the communication between outer machine by the way of wired or wireless, calculates
Module calculates the communication quality value of each interior machine according to the messaging parameter that outer machine transmits, and display module shows messaging parameter, leads to
Believe mass value etc..Communication quality value provides foundation for the number and position that wireless repeater is arranged.
The method of wireless multi-line system internal-external machine communication quality detection and wireless repeater setting is as follows:
(1) internal-external machine communication protocol data increases signal power parameter
Interior machine is issued in the communication protocol data of outer machine, and signal transmission power TxPw and signal reception power RxPw two is increased
A data can use mw or dBm to indicate.
(2) father node fills in signal power data
Interior machine wireless module fills in the signal transmission power TxPw of oneself when issuing outer machine data.The father of last layer saves
The signal reception power RxPw for detecting the interior machine is filled into communication data, so far by point when receiving the interior machine data
TxPw and RxPw data have all been filled in completely.Then proceed to toward upper layer transfers, but TxPw and RxPw data retain always it is constant, directly
To outer machine.
In Fig. 4, by taking 12# as an example, TxPw is filled in by 12# oneself, and RxPw then by its father node 5# according to it is actually detected to
The signal strength of 12# fills in RxPw.
(3) parameter between outer machine and radio communication quality detection device is transmitted
It is assumed that current internal-external machine has been carried out N wheel wireless communications.It often takes turns in communication process, interior machine signal transmission power TxPw
It is not fixed, is being become at any time according to site environment.It is accumulative to there is Ni communication, interior machine using TxPwi in this N wheel communications
When power transmission data, the reception power that father node detected and issued outer machine is all RxPwi.
Radio communication quality detection device is wirelessly or non-wirelessly communicated with the foundation of outer machine, and outer machine passes RxPwi, TxPwi, Ni, N
Give communication quality detection device.
(4) signal transmission power weight is arranged
The corresponding weight Qi of interior machine signal transmission power TxPwi can be arranged in radio communication quality detection device.Emit work(
Rate TxPwi is smaller, indicates that it under the power of very little, can meet the normal communication of internal-external machine, this intermediate Communication Jamming source
Fewer, communication quality is more satisfactory, therefore the weight Qi set will be more greatly.Reference table 1.
(5) calculate and show the communication quality of each interior machine
After period T, internal-external machine has carried out N wheel wireless communications.Within for machine j (j is interior machine number), taken turns in N
Interior, it is all RxPwi to have the reception power that when being sent using TxPwi power, father node detected and issued outer machine Ni times, separately
The corresponding weight of TxPwi power is Qi, then the communication quality calculation formula of this interior machine is:
The communication quality of each interior machine can be calculated and be shown according to above-mentioned formula in radio communication quality detection device.
(6) judge whether number and the position of increase repeater and repeater
Communication quality threshold M ' is set, it is whether normal that current internal-external machine communication conditions are weighed with it.Work as Mj>M ', table
This bright current interior machine communicates normally with outer machine, otherwise needs to increase wireless repeater near this interior machine.Wireless repeater
Position can influence the degree of information enhancement, need that suitable position is selected to meet Mj>M′.It, may if communication quality is very poor
Multiple repeaters are needed to maintain normal internal-external machine to communicate.
As shown in fig. 6, communication quality M15≤M ' of the interior machine 15# shown according to radio communication quality detection device,
15# nearby increases repeater R1.Father node repeater R1 fills in RxPwi according to the actually detected signal strength to 15#, and successively
It reports until outer machine.The position of each mobile relay device R1, will recalculate M15.Suitable position is selected, M15 is made to reach
Maximum simultaneously meets M15>M′.If a repeater cannot meet, increase multiple repeaters, until meeting M15>M′.
