Embodiment
Elaborate below in conjunction with the utility model of embodiment, present embodiment has provided detailed execution mode being to implement under the prerequisite with technical solutions of the utility model, but protection range of the present utility model is not limited to following embodiment.
Please refer to Fig. 1, a kind of towards indoor positioning topological structure adaptive wireless sensing network architecture system, comprising: some terminals 1, carried by the user, comprise unique sign ID, some terminals are uploaded the anchored object data in real time by the mode of direct transmission broadcasting data; Some base stations 22 are arranged on a room area, the anchored object data that receiving terminal is uploaded, and carry out the networking flow process received anchored object data are transmitted; Some triggers 21 are arranged on each doorway of room area, and the inlet/outlet Event triggered trigger of terminal 1 carries out the terminal data collection, and the terminal data that collects is sent; Some repeaters 3 connect base station and trigger, enlarge network range; Repeater 3 receives the anchored object data of base station 22 transmission and the terminal data that trigger 21 sends, and the anchored object data and the terminal data that receive are transmitted; Gateway 4 receives the anchored object data of transmission and the terminal data that trigger sends, or receives anchored object data and the terminal data that repeater 3 is transmitted; Server 5 and PC6 connect gateway 4, receive anchored object data and terminal data, and store and handle, and realize the location.
Terminal 1 is the transmitting terminal of data, is responsible for uploading the anchored object data in real time, need not to network, and directly sends the broadcasting data to trigger 21 or base station 22.The collection of terminal location coordinate data is responsible in base station 22, carries out the networking flow process and is sent to upper level equipment, to originate as locator data.Trigger 21 is responsible for the terminal trigger data acquisition, and networking is uploaded, and in order to assist location, improves positioning accuracy.Repeater 3 is responsible for the data of trigger or base station collection are forwarded to gateway 4(as telegon), and safeguard equipment such as trigger 21 and base station 22 downwards.Gateway mainly is responsible for the foundation of network and is safeguarded the equipment of next stage, guarantees that its child node is lost or when breaking down, reports to the police in the very first time, and transmit and upload data to host computer.
The self-organizing design is adopted in the foundation of network in the utility model, and after the device power, gateway at first detects current channel and whether has other networks, if having, the channel of then selecting to be different from current network is set up network.Base station, trigger, repeater are then distinguished according to the beacon payload value of system's setting and are defined topological structure, be stellate reticulum or tree type network, select the best father node of current demand signal voluntarily by the comparing data link-quality again, application adds network and forms single-stage star network or multilevel star network network.Repeater adopts the split-type design, can adjust selection voluntarily according to indoor scale, namely only uses a cover program network topology then can freely switch between star, tree network, and guarantees networking, the compatibility of maintenance and data.Single-stage star network Organization Chart is seen shown in the accompanying drawing 2.
Multistage tree network framework power consumption control and the data forward efficiencies of relating to more, stationary nodes (base station, trigger, repeater and gateway telegon) and mobile node (terminal) are separated, mobile node does not network, and does not receive internet message, can effectively reduce power consumption.Secondly, network layer is remaining stationary nodes only, but fixed data conversion link then reduce the extra bandwidth that the route Dynamic Selection brings and take, improve the data forward efficiency.For the little little shape zone of area coverage, base station, trigger and gateway telegon are formed stellate reticulum and are got final product, if area coverage is bigger, then increase repeater as transferring equipment.Multistage tree network Organization Chart is seen shown in the accompanying drawing 3.
Transfer of data mostly is unidirectional in the indoor locating system, and network operation can adopt " mechanism of registering ".In the single-stage star network, base station or trigger then need to register to gateway if do not transmit any data in unit period.If gateway is not received base station and any message of trigger in system in the fixed time, think that then it is lost.If base station and trigger make repeated attempts, still can't with his father's node communication, then re-execute the networking flow process.In multistage network, maintenance mechanism is initiated each sub node equipment of active maintenance by the father nodes at different levels in the network.Adopt this maintenance mechanism to have following advantage: (1) stationary nodes hardware is no problem, or is in effective radio-frequency region, then the node loss phenomenon can not occur; (2) there is fault in node hardware or is in outside effective radio-frequency region, then issue warning message in the utmost point short time; (3) maintenance mechanism is one-way communication, does not influence network data transmission speed.
Repeater is the important data relay equipment of native system, except adopting detachable Campatible design, also has data fusion concurrently, data storage forwarding capability.Repeater active analysis locator data is originated, and it is divided into 3 classes: data such as message are replied in (1) base station or trigger self network operation information, configuration, receive then and transmit immediately; (2) terminal alert data because terminal is uploaded the The data broadcast mode, then exists a plurality of base stations or trigger to upload the forwarding phenomenon simultaneously, and repeater then adopts the homogeneous data syncretizing mechanism, filters duplicate message and transmits immediately; (2) terminal positioning data also are broadcast modes, and data are more and bigger to location precision, and repeater then adopts store-and-forward mechanism, effectively judge relevant valid data amount, and unified the collection again transmitted.
More than disclosed only be the application's a specific embodiment, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection range.
