Description
Technical field
The invention belongs to wireless communication technology field, particularly the applied technical field of ZigBee technology, relate to the power-economizing method of a kind of dormancy awakening based on ZigBee technology.
Background technology
In the application scenes of ZigBee technology, it is desirable to Zigbee system is in long-term unattended duty, system interior joint adopts battery powered mode and disclosure satisfy that the requirement on the working time. Such as in some industrial monitorings, battery powered node is adopted to need the system can normal operation several years; In bridge tunnel safety monitoring, the mode being replaced as frequently as battery for substantial amounts of Zigbee node is also unpractical; And in the system application such as some radio meter registers, it is not necessary to Real-time Monitoring Data, but enable a system to meet temporal requirement used above in 2 years. Therefore, following problem is there is: (1) data information acquisition cycle is long in these typical Zigbee system application scenarios, the node data transmitting-receiving time is short, and the node most of the time is at its idle state, wastes the substantial amounts of energy of node. (2) in Zigbee system, offered load is unbalanced, and in network, key node energy expenditure is fast, and the working time of key node determines the normal use of whole network. (3) supply of Zigbee node energy own is limited, and Zigbee system interior joint is once occur that energy is under-supply, just influences whether the normal use of whole system, adds maintenance difficulties and the cost of system simultaneously.
Summary of the invention
In view of this, it is an object of the invention to provide the power-economizing method of a kind of dormancy awakening based on ZigBee technology, the method adopts the power-economizing method increasing dormancy time to reach energy-conservation purpose in ZigBee system.
For reaching above-mentioned purpose, the present invention provides following technical scheme:
A kind of power-economizing method of the dormancy awakening based on ZigBee technology, the method comprises the following steps:
S1: coordinator node is set up tree clustered network, terminal node and routing node and added in the network that coordinator is set up;
S2: network is carried out classification, network node carries out time synchronized with upper level step by step, finally reaches the whole network time synchronized with coordinator;
S3: terminal node and routing node enter duty cycle, terminal node carries out the collection transmission of data, and routing node forwards the data to even higher level of node;
S4: after coordinator receives the data that terminal node is uploaded, sends dormancy to routing node and controls information, and routing node forwards dormancy to control information to terminal node;
S5: node receives dormancy instruction, arranges dormancy time and controls parameter, and enter resting state;
S6: dormancy time arrives, node synchronized wake-up adds network and enters duty.
Further, in step s 4, described dormancy control information comprises when enter dormancy and two parameters of dormancy time length.
The beneficial effects of the present invention is: the power-economizing method of dormancy awakening is applied to Zigbee system by the present invention, make Zigbee node be in low power consumpting state for a long time by increasing dormancy time, it is adaptable to the Zigbee system of the dormancy of long periodicity work. The present invention can not only reduce the consumption of Zigbee system capacity, improves capacity usage ratio, extends the use time of Zigbee system, also can reduce the maintenance cost of network simultaneously, is conducive to promoting the ZigBee technology application in each field.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
Fig. 1 show the ZigBee periodic mode of operation of system interior joint. Comprising duty and resting state in node working mode, wherein duty comprises node time synchronization and duty cycle, and duty cycle carries out collection and the forwarding of data, and rest period node enters low power consumpting state.
Fig. 2 show ZigBee system architecture diagram, and system adopts tree clustered network topology, it is simple to coordinator management network and network is carried out classification. In figure, ZC is coordinator, and Ri (i=1,2,3) is router, and ZDi (i=1,2,3 ...) is terminal node. Wherein coordinator ZC building network, routing node carries out data forwarding, and terminal node ZDi carries out the collection of data and uploads.
Comprising duty and resting state in the periodic mode of operation of ZigBee node, its concrete workflow is as shown in Figure 3. Task in duty has been time synchronized and the data transmission of network node, and resting state interior joint is in low power consumpting state, and ZigBee node in working order and is circulated switching between resting state.
The park mode of ZigBee node adopts shallow dormancy mode. This mode is applicable to the periodic mode of operation of node, and runs can provide timing wake-up accurately for ZigBee-network. Resting state interior joint enters low power consumpting state, and wherein the wireless transceiver of low power consumpting state interior joint is closed, memorizer cuts out, and the network information stores in the nonvolatile memory, and audio oscillator works, and provides local clock for doze output.
The synchronous method of ZigBee node adopts the thinking synchronized step by step. As shown in Figure 4, network being carried out classification, coordinator is as 0 grade, and routing node is as 1 grade, and terminal node is as 2 grades. Using the coordinator clock standard time clock as ZigBee-network. Routing node and coordinator carry out time synchronized, and terminal node and routing node carry out time synchronized, finally reach the whole network time synchronized based on the coordinator time.
The long-time dormancy timing of ZigBee node adopts the method for doze output periodic duty to reach long-time timing (as shown in Figure 5). The method adopting " delivery " in concrete methods of realizing, reaches the purpose of long-time timing by arranging the time T of timing parameters M and intervalometer, and timing arrives, and doze output produces interrupt signal and wakes ZigBee node up. Fig. 6 is the method flow diagram of ZigBee long-time timing dormancy.
What finally illustrate is, preferred embodiment above is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail by above preferred embodiment, but skilled artisan would appreciate that, in the form and details it can be made various change, without departing from claims of the present invention limited range.
