Abstract
The invention discloses a drop and pull transport wireless sensor energy-saving method based on a WSN. The drop and pull transport wireless sensor energy-saving method comprises the steps that a node wakening mechanism is introduced, and a processing module conducts data filter and fusion and adds a miniature vibration generator to a node. According to the drop and pull transport wireless sensor energy-saving method, the node wakening mechanism is applied to a wireless sensor, the node in the WSN is wakened selectively according to the demand of a logistics company, and the node is in the dormant state at other moments; the data filter and fusion mechanism is applied, information collection with special emphasis is conducted according to a received order, information entropy redundancy can be reduced, data fusion is conducted on collected data at the same time, the number of redundant data is further reduced, and energy consumption caused in the process of data transmission is reduced; the miniature vibration generator is applied to the wireless sensor node, so that electric energy is provided for the node.
Description
Technical field
The present invention relates to a kind ofly based on getting rid of of WSN, hang in transport trailer information gathering process, according to trailer operational characteristics, realize the energy-conservation method of wireless senser.
Background technology
Get rid of and hang transportation as a kind of novel Transportation Organization form, greatly met logistics transportation efficiently, demand easily.And along with logistics company is by the introducing of WSN technology, company can be monitored in real time to trailer, convenient logistics company is to the configuration of tractor and trailer and management.
The microminiaturization of sensor node, the energy content of battery of node is limited, and because physical restriction is difficult to node replacement battery, so the restriction of the energy content of battery of sensor node is that whole wireless sensor network relates to one of constraint of most critical, it has directly determined job stability and the life-span of network.The catabiotic module of sensor node comprises sensor assembly, processor module and wireless communication module, wherein the energy consumption of the overwhelming majority is on wireless communication module, and the required energy of 1bit communication 100m distance is about as much as and carries out 3000 energy that computations consumes conventionally.
Get rid of and hang in transportation, due to the high utilization rate of trailer, higher load condition, cause wireless senser often in running status, cause wireless senser energy consumption to strengthen, be unfavorable for safeguarding.
Summary of the invention
In order to solve, in prior art, above-mentioned environmental change is frequent, node energy consumption strengthens, short problem of transducer effective time, and this law invention provides a kind of and hung the energy-conservation method of transportation wireless senser based on getting rid of of WSN.
Technical scheme of the present invention comprises that node adds miniature vibration electric generator, introduces node arouse machine processed, and processing module is carried out data filtering and fusion etc.Node adds miniature vibration electric generator can provide power supply for transducer, uninterrupted power supply in trailer running; Introduce node arouse machine processed, can make transducer power cutoff or be placed in sleep pattern to reduce electric quantity consumption when not needing image data; Data processing module can reduce volume of transmitted data by compression fused data.
Described wireless senser adopts node arouse machine processed, data filtering and syncretizing mechanism; The job step that described node wakes up is for starting; Input command; Search node, does not search node and continues search; After searching node, send wake command; Node wakes up; Node carries out information gathering; Carry out the processing of Information Monitoring; Information is fed back, and does not feed back, and continues information gathering and information processing step; After information feedback, logistics company is received information; Logistics company sends sleep command, node dormancy; Finish.
Data filtering and data fusion mechanism are transducer Information Monitoring; Analytical information; Carry out information fusion, reduce redundant data.
The node of described wireless senser adopts miniature vibration electric generator, for described node provides electric energy.
Adopt technical scheme of the present invention, adopt arouse machine processed that node is temporarily quit work when not needing Information Monitoring; Data fusion and filtration can reduce redundant information, and the energy consumption that reduces transfer of data is saved the energy of node.Adding miniature vibration electric generator can provide power supply for node, realizes continual power supply, reduces loaded down with trivial details maintenance work.
Accompanying drawing explanation
Fig. 1 is a kind of WSN node workflow diagram of hanging the energy-conservation method of transportation wireless senser that gets rid of based on WSN of the present invention.
Fig. 2 is that a kind of extension that gets rid of based on WSN of the present invention transports the energy-conservation method wireless senser of wireless senser arouse machine processed flow chart.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Based on getting rid of of WSN, hanging the energy-conservation method of wireless senser in transportation, is on the energy-conservation basis of traditional sensors node, in conjunction with the feature of trailer running and the emphasis of Information Monitoring, has realized and has got rid of that to hang in transportation wireless senser energy-conservation.
Aspect power supply, because vehicle-mounted wireless sensor is often kept in motion, therefore can use miniature vibration electric generator, utilize piezoelectric principle that the vibrational energy in motion is converted into electric energy, for transducer provides power supply; Aspect data acquisition and processing (DAP), because hang in transportation based on getting rid of of WSN, in transducer overwhelming majority situation, be in order to determine the position of trailer, and small part is in order to collect other information of trailer, as load-carrying etc., so transducer can have the information gathering stressing according to the order of receiving, can reduce comentropy redundancy, can carry out Data Fusion to the information gathering simultaneously, further reduce redundant data, reduce the energy consumption in transfer of data; Aspect working sensor, can introduce arouse machine processed, the node in wireless sensor network, according to the needs of logistics company, optionally wakes node up, and other processes resting state constantly, can be energy-conservation to a certain extent.
As shown in Figure 1, the workflow step of WSN node is to start; Node receives orders, and carries out node and wakes up; Analyze order; According to order, transducer carries out information gathering; Analytical information, removes relevant redundancy information, carries out information fusion, and transmission information enters the wait command stage; Do not receive sleep command, continue wait command, receive sleep command, enter the dormant stage; Finish.
As shown in Figure 2, the job step that node wakes up is for starting; Input command; Search node, does not search node and continues search; After searching node, send wake command; Node wakes up; Node carries out information gathering; Carry out the processing of Information Monitoring; Information is fed back, and does not feed back, and continues information gathering and information processing step; After information feedback, logistics company is received information; Logistics company sends sleep command, node dormancy; Finish.
