An embodiment
See also Fig. 1, a kind of flow chart that it shows a kind of micro power radio communication network address assignment method that the application provides can comprise the following steps:
Step S11: choose the minimum relaying rank of relaying rank in each relaying rank that never was selected as current relaying rank.
In the present embodiment, in micropower wireless local network, communication system comprises a Centroid and a plurality of trunking, and wherein, trunking can be used as target device.Centroid is the trunking traffic promoter.
Each trunking in micropower wireless local network in communication system is in the trunking traffic of once determining arbitrarily, and the relaying rank of each trunking is known definite.And in the trunking traffic of once determining arbitrarily, the relaying rank of a plurality of trunkings can identically be that same relaying rank can corresponding a plurality of trunkings.But the normal address of each trunking that each relaying rank is corresponding is different.
In the present embodiment, can be directly and the corresponding relaying rank of trunking that communicates of trunking traffic promoter be minimum rank in all relaying ranks, namely can be directly and the corresponding relaying rank of trunking that communicates of Centroid be minimum rank in all relaying ranks.Can be directly and the corresponding relaying rank of trunking that communicates of Centroid be set to 0 grade, can certainly be set to other any one relaying ranks.
In the present embodiment, in the trunking traffic of once determining arbitrarily, the corresponding relaying rank of trunking direct and that Centroid communicates is 0 grade.
Take the relaying rank that was not selected as 0,1,2 and 3 as example, describe as other process of current Relay choosing the minimum relaying rank of relaying rank in the relaying rank that never was selected, choose 0 grade of minimum relaying rank in the relaying rank 0,1 that never was selected, 2 and 3 as current relaying rank.1,2 and 3 become the relaying rank that was not selected, and in choosing in the relaying rank 1 that never was selected, 2 and 3,1 grade of minimum relaying rank is as current relaying rank.2 and 3 become the relaying rank that was not selected, and choose minimum relaying rank 2 in the relaying rank 2 and 3 that never was selected as current relaying rank.3 become the relaying rank that was not selected, with minimum relaying rank 3 as current relaying rank.
Step S12: judge that described current relaying rank is whether greater than directly and the corresponding relaying rank of trunking that communicates of trunking traffic promoter.
The corresponding relaying rank of trunking that if current relaying rank is not more than directly and the trunking traffic promoter communicates, execution step S13, if the corresponding relaying rank of trunking that current relaying rank communicates greater than direct and trunking traffic promoter, execution step S14.
Step S13: send the trunking of broadcasting command to each unallocated network address corresponding to current relaying rank.
When the corresponding relaying rank of trunking that current relaying rank is not more than directly and the trunking traffic promoter communicates, Centroid directly sends the trunking of broadcasting command to each unallocated network address corresponding to current relaying rank.
Step S14: determine that the relaying rank less than current relaying rank one-level is the intermediate relay rank.
Current relaying rank greater than directly and the trunking traffic promoter communicate the corresponding relaying rank of trunking the time, Centroid is described and less than other each relaying rank of current Relay separately corresponding trunking carried out trunking traffic, Centroid is with after corresponding trunking carries out trunking traffic separately less than other each relaying rank of current Relay, the communication path of can the records center node corresponding with each relaying rank trunking.
Step S15: send the trunking of broadcasting command to the address of distribution network corresponding to described intermediate relay rank, the trunking by the address of distribution network corresponding to intermediate relay rank forwards the trunking of described broadcasting command to each unallocated network address corresponding to current relaying rank.
The trunking of the address of distribution network that can only be corresponding with the intermediate relay rank due to the trunking of each unallocated network address corresponding to current relaying rank carries out direct communication, therefore needs the trunking of the address of distribution network corresponding to intermediate relay rank to forward the trunking of broadcasting command to each unallocated network address corresponding to current relaying rank.
In the present embodiment, the communication path of the trunking of the distribution network address corresponding with the intermediate relay rank of by Centroid, recording, send the trunking of broadcasting command to the address of distribution network corresponding to intermediate relay rank, then the trunking by the address of distribution network corresponding to intermediate relay rank forwards the trunking of broadcasting command to each unallocated network address corresponding to current relaying rank.
Step S16:, every the first Preset Time, judge whether to receive the normal address that the trunking of the described unallocated network address returns.
Centroid in the time of can forwarding broadcasting command take the trunking of the address of distribution network corresponding to intermediate relay rank corresponding time as zero-time,, every the first Preset Time, judge whether to receive the normal address separately that the trunking of the unallocated network address returns.Corresponding time when certainly the zero-time trunking that is not limited to the address of distribution network corresponding to above-mentioned intermediate relay rank forwards broadcasting command.
Every the first Preset Time, judge whether to receive normal address that the trunking of the unallocated network address in the normal address that the trunking of described each unallocated network address returns the returns trunking by the address of distribution network corresponding to intermediate relay rank and forward, be forwarded to Centroid.
When judgment result is that the normal address that the trunking that do not receive the unallocated network address returns, execution step S17.When judgment result is that the normal address that the trunking that receives the unallocated network address returns, execution step S18.
Step S17: and the non-judgement for the first time of current judgement, this judgement stopped.
During the normal address returned for the trunking that does not receive the unallocated network address in the result of current judgement, and current be judged as first the judgement, can't stop this judgement, but carry out again once judgement after the Preset Time of interval,, if judged result is still no, stop judging whether receiving the normal address that the trunking of the unallocated network address returns.
During the normal address returned for the trunking that does not receive the unallocated network address in the result of current judgement, and currently be judged as non-judgement for the first time, just can stop judging whether receiving the normal address that the trunking of the unallocated network address returns., to guarantee really do not had trunking to return to normal address, avoid just stopping judgement in trunking returns to the process of normal address, and the situation that causes not receiving the normal address that trunking returns occurs.
Step S18: the normal address that described trunking is returned is stored in the first list.
After the normal address that the trunking that receives the unallocated network address returns, the normal address of trunking is stored in the first list.
Step S19: choose the trunking of any one unallocated network address corresponding to the normal address of storing in described the first list as current trunking to be allocated.
In the present embodiment, can store a plurality of normal addresses in the first list, each normal address of storage is corresponding the trunking of unique unallocated network address separately.
Choose the trunking of any one trunking as the current network address to be allocated in the trunking of the unallocated network address that Centroid is stored from the first list normal address is corresponding.
Due to each normal address corresponding trunking of unique unallocated network address separately, therefore can be by to choose the normal address that any one was not chosen from the first list, the trunking of the unallocated network address that this normal address is corresponding is as current trunking to be allocated.
Step S110: distribute and send unique network address to described current trunking to be allocated, the size of the described network address is less than the size of described normal address.
Current trunking to be allocated after being assigned with the network address, is converted to the trunking of distribution network address.
Step S111: judge the trunking that whether has the unallocated network address in trunking corresponding to the normal address of storing in described the first list.
, if judgment result is that the trunking that has the unallocated network address in trunking corresponding to the normal address of storing in the first list, return to execution step S19., if judgment result is that the trunking that does not have the unallocated network address in trunking corresponding to the normal address of storing in the first list, illustrate that trunking corresponding to normal address of storing in the first list all has been assigned with the network address, execution step S11.
When all relaying ranks all were selected, there do not is the relaying rank that was not selected, when not having the relaying rank that was not selected, just no longer return in each relaying rank that execution never was selected and choose any one relaying rank as current this step of relaying rank.
In this application, redistribute the network address by being respectively each trunking corresponding to each relaying rank, and the size of the network address is less than the size of each trunking normal address, make packet contain the network address of the trunking of same number, the size of the forward-path of its formation is less than the size of the forward-path of normal address formation, therefore the complete time shorten used of transfer of data, thus the efficiency of transmission and the real-time of with target device, communicating by letter of data improved.
A kind of micro power radio communication address distribution method shown in Fig. 1 is except comprising each method step shown in Fig. 1, can also comprise: when receiving described current trunking to be allocated and confirm to have received the feedback message of the described network address, the described network address is stored in the second list.
In the present embodiment, also the second Preset Time can be set, be used for when the time that the current trunking confirmation to be allocated of wait reception has received the feedback message of the network address surpasses the second Preset Time the normal address corresponding to trunking current to be allocated of storing in deletion the first list.
In the said method step, in communication system, byte length corresponding to normal address is generally 6 bytes in micropower wireless local network.In the situation that byte length corresponding to normal address is 6 bytes, the byte length of the network address can be set to any one in 2 bytes, 3 bytes, 4 bytes and 5 bytes, can choose the network address of using respective byte length according to the number of the trunking in communication system in micropower wireless local network.For example, the number of the trunking in communication system is not more than (2 in micropower wireless local network
16When-1) individual, can use byte length is the network address of 2 bytes.The number of the trunking in micropower wireless local network in communication system is not more than (2
24When-1) individual, can use byte length is the network address of 3 bytes.The number of the trunking in micropower wireless local network in communication system is not more than (2
32When-1) individual, can use byte length is the network address of 4 bytes.The number of the trunking in micropower wireless local network in communication system is not more than (2
40When-1) individual, can use byte length is the network address of 5 bytes.
In communication system, the number of trunking is generally 10000 left and right, much smaller than (2 in micropower wireless local network
48-1) individual, therefore there is no need to use byte length is the normal address of 6 bytes, can be according to the concrete number of the trunking in communication system in micropower wireless local network, the network address of distributing respective byte length, improve different communication systems and chosen the flexibility of the network address, and, due to the network address of using byte length less than byte length corresponding to normal address, improved efficiency of transmission, with the real-time of with target device, communicating by letter.
