Exist on described DC power line the priority of data collision and the radiating circuit of self 300 relatively low time,
The radiating circuit 300 inhibited itself from works, until this radiating circuit 300 reaches the highest priority, from
And achieve the priority according to equipment and the communication information shooting sequence of these equipment is ranked up.
Illustrate, see the equipment task time graph of a relation shown in Fig. 4, it is assumed that have 4 equipment simultaneously
Launching communication information, in the t0 moment, equipment 1 utilizes controller 100 to detect on described DC power line height
Level pulse, and the pulse of self correspondence is low level, then judge that own priority is relatively low, follow-up exits
Do not retransmit data (in figure, dash area represents the equipment out-of-work time period), remaining equipment 2,
3,4 continue to send；In like manner t1In the moment, equipment 2 detects that own priority is low, actively exits；t3Time
Quarter, equipment 4 exited, and the most surplus so last equipment 3 continues to send data, thus avoids data collision
Occur, it is ensured that the accurate delivery of data.
