Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
In order to complete understanding the present invention, refer to numerous concrete details in the following detailed description, but it should be appreciated by those skilled in the art that the present invention can realize without the need to these details.In other embodiments, be not described in detail known method, process, assembly and circuit, in order to avoid unnecessarily cause embodiment fuzzy.
Embodiment one
Fig. 1 is the exemplary process diagram of the bus system power consumption control method that the embodiment of the present invention one provides.This bus system comprises the multiple nodes in bus control equipment and bus, and multiple node is divided into two or more grouping; The method is used for bus control equipment.
Shown in Figure 1, the method can comprise:
S101, with broadcast mode send initial settings information, start alternately to enter duty to become working group or enter dormant state become dormancy group to make each grouping, wherein said initial settings information comprises: each grouping becomes the quantity of the serial number of working group, the default operating time of working group and described grouping successively.
The basic ideas of the present embodiment are: be first multiple grouping by node division all in bus, these groupings alternately enter duty and dormant state, reduce total system power consumption with this.In running order grouping can be called working group, and the grouping being in dormant state can be called dormancy group.Meanwhile, doze output be set on each node and wake timer up, by these timers, node being changed in working order and between dormant state.Bus control equipment, for controlling all nodes hung in bus, broadcasts initial settings information when initial, and to realize when working to each grouping, when dormancy is configured.
After node receives initial configuration information, according to the default operating time of working group, number of packet and from the sequence in serial number, just can calculate the cycle of self work dormancy.Such as, suppose there are 3 groupings, be grouping 1, grouping 2 and grouping 3 in order respectively, it is 50ms that working group presets the efforts time.So for grouping 1, then should first work 50ms, the then dormancy when grouping 2 works, the also dormancy when grouping 3 works, thus grouping 1 work dormancy period as shown in table 1 below:
Table 1
| Work | Dormancy | Dormancy | Work | Dormancy | Dormancy | … |
| 50ms | 50ms | 50ms | 50ms | 50ms | 50ms | … |
Also namely work 50ms, dormancy 2x50ms, and then the 50ms that works, dormancy 2x50ms ... circulation like this.
In like manner, for grouping 2, then should first dormancy 50ms(now to divide into groups 1 work), then work 50ms, secondary dormancy 50ms(now divides into groups 3 work), secondary dormancy 50ms(now takes turns to again grouping 1 and works), so the work of grouping 2 dormancy period as shown in table 2 below:
Table 2
| Dormancy | Work | Dormancy | Dormancy | Work | Dormancy | … |
| 50ms | 50ms | 50ms | 50ms | 50ms | 50ms | … |
Also i.e. dormancy 50ms, work 50ms, dormancy 50ms, and then dormancy 50ms, work 50ms, dormancy 50ms ... circulation like this.
In like manner, divide into groups 3 work dormancy period as shown in table 3 below:
Table 3
| Dormancy | Dormancy | Work | Dormancy | Dormancy | Work | … |
| 50ms | 50ms | 50ms | 50ms | 50ms | 50ms | … |
Also be dormancy 2x50ms, work 50ms, and then dormancy 2x50ms, work 50ms ... circulation like this.
S102, with broadcast mode periodically transmitting time synchronizing information, to make the node in working group according to the dormancy count down information of the described time synchronization information correction self received, wherein said time synchronization information at least comprises: the mark of the current grouping as working group, the remaining operating time of working group.
Node can be arranged two timers, i.e. doze output and wake timer up, wherein doze output works when node is in running order, for carrying out countdown to entering dormant state, also namely carries out countdown to the remaining working time; Wake timer up then contrary, work when node dormancy, carry out countdown for coming back to duty to node, also namely countdown is carried out to remaining dormancy time.
In the ordinary course of things, the timer of node may produce some cumulative errorss, causes the working time not realize by ideal situation, or perhaps it is synchronous not reach with system, now just need the residue operating time information to node, also namely dormancy count down information is revised.Described dormancy count down information can be a duration, such as, be: node should enter dormant state after 25ms; Can also be a moment, such as, be: node should divide Z W second this moment of millisecond to enter dormancy by Y when X, does not limit this present embodiment.
After node in working group receives the time synchronization information of broadcast, the mark of being divided into groups by comparison can know whether this time synchronization information is the grouping of issuing belonging to this node, if so, the dormancy count down information of the remaining operating time of the working group in time synchronization information to self is then utilized to revise.Such as, the dormancy countdown also surplus 18ms that this node is original, and the work residual time length of time synchronization information instruction is 21ms, then dormancy countdown should be revised as 21ms from 18ms by this node.
The present embodiment makes respectively to be grouped between duty and dormant state by above-mentioned timesharing dormancy mechanism and switches, ensure to only have a collection of node in running order at synchronization, all the other enter dormant state, and realize the time synchronized with bus control device by the time synchronization information receiving bus control device, the time error of each node being accumulated generation because of reasons such as dormancy is eliminated with this Time Synchronization Mechanism, ensure that time synchronized, thus finally reach and both reduced total system power consumption, ensure again the beneficial effect of communication quality.Particularly such as under the occasion that colliery etc. is high to security requirement, the technical scheme that the present embodiment provides can meet associated safety authentication requesting.
In addition, in the present embodiment or the present invention's some other embodiments, described method can also comprise:
Data access is carried out to the current node be in working group, wherein said working group at one time in only include a grouping.In other words, namely the same time only has a grouping to become described working group.
Under some scenes, bus only has at most a grouping to enter duty at synchronization becomes working group, and other groupings enter low power operation state as dormancy group; And under other scene, the grouping in working group also can have multiple, namely there is multiple grouping to enter duty simultaneously.In the present embodiment, the preferred same time only has a grouping to become described working group.
