In order in various application scenarioss, all to prolong in the wireless sense network each node power useful life effectively; The utility model embodiment provides a kind of managing power consumption system of wireless sense network sensor node; As shown in Figure 1, comprising: comprise management node 1 and sensor node 2; Management node 1 comprises task scheduling modules 11;
Make regularly to start module 21, said CPU25 entering normal operation mode and start sensor 23 are passed carry out the sensor conversion at setting-up time startup CPU25;
Make mode control module 22 after the start sensor conversion, Controlled CPU 25 gets into low-power consumption mode;
After said transducer converts, make mode control module 22 Controlled CPU 25 get into normal operation mode and read the information data that said transducer 23 is gathered;
Make wireless transmit unit control module 24 start wireless transmit parts power supply, after the transmission of wireless transmit parts comprises that the upstream data of the information data of sensor acquisition finishes, close wireless transmit parts power supply;
Make mode control module 22 after closing wireless transmit parts power supply, Controlled CPU 25 gets into park mode.
Because generally speaking; Sensor node does not need round-the-clock operation; For this reason; In the utility model embodiment,, come that the timing in the sensor node 2 is started module 21, mode control module 22, transducer 23 and wireless transmit unit control module 24 and control through being provided with task scheduling modules 11 in the operating system in management node 1; Thereby making does not need in the time period of work sensor node 2 to be set to resting state at sensor node 2, through being provided with timing device, can sensor node 2 waken up and starting in the time of setting; After sensor node 2 starts, will the start sensor conversion.Because the power consumption of 2 resting states of transducer joint is out and away less than the power consumption of sensor node 2 starting states, so, through sensor node 2 being set to the power supply useful life that dormancy can prolong sensor node 2 effectively.

For this reason; In the utility model embodiment,, thereby avoid sending repeating data to server end through of the information data deletion of redundant data removing module with resultant repetition in the same router node; And then reduced the traffic volume of routing node data; Also just reduce the startup duration and the number of starts of the wireless transmit parts of routing node thus, thereby also just reduced the power consumption of routing node effectively, and then also just increased the useful life of routing node power supply effectively.
In another embodiment of the utility model, in the technical scheme in adopting the foregoing description, also comprise road routing management policy module, the routing management policy module is used for:
According to the routing table of all routing nodes, draw the frequency of utilization of each routing node;
When calculating the transmitting uplink data path of routing node, the source address of obtaining said upstream data is to all active link paths between the destination address; The path that selection routing node number is few and frequency of utilization routing node is low in all active link paths is as said transmission of uplink data path.
As far as whole wireless sensor network, need consider how information data is delivered to the destination from data source from the overall situation.In order between source and destination ground, to find an energy-conservation multi-hop routed path, can select.Can in all active link paths, select the few path of routing node number, but the life span that may not necessarily prolong routing node in the network like this, because some routing node that is in key position possibly and cause power supply to exhaust too early by excessive use.For avoiding this situation; Organizer's telegon in the wireless sense network need be known the frequency of utilization of each routing node through the routing table of routing node; Thereby can estimate the energy consumption load of each routing node, and then, through calculating the possible path that all node datas are uploaded; The routing table of each routing node is carried out equilibrium distribute, guarantee to reach balanced in the use of all routing nodes.
In the utility model embodiment, can also comprise that sensor node starts policy module, sensor node starts policy module, is used for the sensor node of confirming that needs start; When the start sensor node, only startup needs the sensor node of startup.
In practical application, being distributed with of sensor node may be very intensive, so the information data that might make a plurality of sensor nodes be transferred in the same routing node is repetition; Such as, in the same area, the temperature data that the temperature sensor of contiguous a plurality of sensor nodes might collect is the same; So; In this case, need not start all the sensors node, for this reason; Can come to reduce effectively the power consumption of sensor node through the startup quantity that reduces sensor node, thereby prolong the useful life of sensor node power supply effectively.
