The basic ideas of the present embodiment are：Be first multiple packets by all node divisions in bus, these packet alternately into
Enter working status and resting state, total system power consumption is reduced with this.In running order packet is properly termed as working group, place
Dormancy group is properly termed as in the packet of resting state.Meanwhile doze output is set on each node and wakes up timer, lead to
Crossing these timers makes node be changed between working status and resting state.Bus control equipment is used to control all extensions
Node in bus, broadcasts initial settings information at the beginning, to realize to when when each packet work
Dormancy is configured.
After node receives initial configuration information, according to the default operating time of working group, number of packet and from suitable
Sequence numbering in sequence, can be calculated itself work dormancy cycle.For example, it is assumed that there are 3 packets, divide in sequence
It is not packet 1, packet 2 and packet 3, it is 50ms that working group, which presets the efforts time,., then should first work so for packet 1
Make 50ms, then be grouped 2 work when dormancy, be grouped 3 work when also dormancy, so packet 1 work dormancy period it is as follows
