Fig. 2 show and positions schematic diagram according to embodiments of the present invention.Employ wireless Internet of Things and sensor technology just can easily realize required monitoring personnel, the indoor positioning of outer visitor (or valuables, assets, facility etc.) is followed the trail of, positioning precision is high, and can on the server " monitoring data " be carried out the intellectual analysis management of centralization, and equipment cost is relatively low, reliability is high, and application deployment are simple, it is easy to promote.When design, we have employed the comprehensive application technologies such as spatial geographic information technology, wireless aware and transducer room inner position, achieve monitoring personnel, the indoor positioning tracing monitoring of outer visitor (or valuables, assets, facility etc.), and it is able to record that the travel region detailed route track of monitored personnel (if or asset equipment moved) and the playback monitoring of walking route.
According to the location schematic diagram shown in Fig. 2, indoor accurate position to be realized, first have to solve wireless senser location algorithm.Native system mainly have studied indoor wireless location technology based on ZigBee sensor network and the realization of locating and tracking system.Native system carries out new integration wireless location algorithm RSSI and LQI value, have developed novel " numerical value combined method "." numerical value combined method " is to have passed through the analysis to a large amount of measured datas, summarizes the transportation law of signal, it is established that novel location model.As we know that in three dimensions it is known that 1 some distance to 4 known reference point, it is possible to determine that the coordinate of this point, this point are the same with the ultimate principle of global positioning system (GPS).Only in wireless sensor network, coordinate system is two-dimensional space to be synchronized also without clock, therefore, as long as being aware of 1 node to be assured that the position of node to the distance of 3 reference modes.
Single-measurement distance can be expressed as:
Single approximate distance is represented by:
As above-mentioned, the actual position of node is made up of approximation component and 2 parts of increment:
Therefore, have:
On the right of above formula, function Taylor series are according to being launched into:
Non-linear in order to eliminate, intercept after 1 rank partial derivative in above-mentioned expansion is every, and then expression formula is rearranged so that known quantity is on the left side, and unknown quantity is on the right.Obtain:
Obtain through abbreviation:
So to determine the coordinate of 1 point in two-dimensional space, it is necessary to there are at least 3 reference modes.In wireless sensor network, the connection between node is a lot, and most of nodes can directly or indirectly obtain the distance of the reference point of more than 3.Therefore equation group can be obtained:
Can be calculated through derivation abbreviation:
Use above formula, it is possible to obtain the general distance of node location to be positioned and physical location.
In theory, RSSI is institute's through-put power and the function of distance between receiving-transmitting sides.Increase along with distance is reduced by received signal strength, and below equation gives the theory relation of RSSI and distance d.Wherein, n is model propagation constant, also referred to as spread index；D is the distance to signal sender.A is the received signal strength value at 1 meter.
Zigbee signal intensity is with distance monotonic decay, and received signal strength value decreases notably in 10m spacing, and more than 10 meters, then change tends towards stability.RSSI value is to (d, RSSI), and the most mobile node to be positioned, each node to be positioned obtains one group of data { (d, RSSI) }.The equation of digital simulation curve is:
Above formula obtains the relational expression of RSSI and distance, and other unknown signaling intensity level can be converted into corresponding distance d by these relational expressions.There is euclidean distance between node pair information, it is possible to obtain the position coordinates of unknown node.
LQI with RSSI is the same, can obtain when Zigbee transceiver module often receives a Frame, and it can reflect the change of signal intensity and the change of experienced interference in time.The dynamic range of LQI is 0 ~ 255, bigger than RSSI so that it has higher resolution.LQI and RSSI still has good concordance.
The equation of one section of matched curve is:
The equation of two sections of matched curves is:
LQI has the variation phenomenon of similar RSSI, i.e. LQI and also has the trend successively decreased with distance.It practice, the acquisition of LQI has substantial connection with RSSI.Therefore, LQI value is incorporated distance technique method by native system has had bigger raising by the precision making the ranging technology of RSSI.
And " the numerical value combined method " of native system application, it is exactly that RSSI location and LQI location are combined, curve-fitting method and numerical value matching method are wanted to combine, and make full use of concrete applied environment, choose different localization methods, be dynamically selected mode outstanding in each distance segment and carry out technology distance, and according to RSSI(or LQI) fluctuation range, to RSSI(or LQI) carry out certain correction, thus improve positioning precision.Specifically, this localization method realizes including three parts: the acquisition of range information, Nodal Arranging Scheme and network positions algorithm.
Comprehensive data above formula calculates and analyzes and can obtain, can be informed in reference mode density certain in the case of, improve several principles of positioning precision:
(1), when nodal distance is in 10 meters, LQI value is used to obtain range information；When nodal distance is more than 10 meters, obtain range information by RSSI value；
(2) when using curve-fitting method, by segmentation as much as possible for fading curve, increase the line segment number approached and carry out more accurate piecewise approximation fading curve；
(3) every kind of applied environment has its particularity, makes full use of the particularity of environmental information, can effectively reduce the complexity that location realizes.
Native system, for indoor positioning, uses the layout of reference point effectively to arrange through calculating test.
In house interior, reference point being installed equilateral triangle and arranges, so what time how moving all will in the triangles, and the length of side of appropriate design triangle can reach preferable setting accuracy.
Such as Fig. 3 a, dashed rectangle district represents that space to be positioned, solid black circle represent reference mode, and five-pointed star represents mobile node.The length of side assuming the distance between reference mode, i.e. equilateral triangle is x, and the quantity of the reference mode in this region is n, then:
The actual environment distance represented such as Fig. 3 b disposes calculating, for representing in monitoring region, the node being connected with PC is after receiving all of RSSI and LQI packet, deliver a packet on system software platform, to RSSI(LQI) value sequencing selection maximum of which three as the strongest reference point around blind node, and by RSSI(LQI) value installation environment model conversation become distance d value.
Fig. 4 show the location figure calculating figure according to embodiment of the present invention.Calculate according to Fig. 4, as follows:
In figure, B, C, D are three reference modes around unknown node, and A represents node to be positioned.When unknown node A receives the framing signal that B, C send, according to RSSI or LQI and the position of beaconing nodes B, C, distance d1=L1(ab can be obtained), d2=L2(ab).Thus obtaining 2 trianglees, A1 and A2 is 2 two possible positions of node A.And when mobile node A receives the 3rd framing signal that beaconing nodes D sends, d3=L (ad) can be obtained；By calculating the position that may determine that A more for a long time.Calculated by publicity and can obtain the approximate coordinate value of A:
By so calculating, can be in the case of relatively low complexity, the most simply, conveniently, and positioning function calculates accurately.Decrease the workload of sample magnitude simultaneously.Therefore technical scheme not only precision but also guaranteed localization method.
The above, simply presently preferred embodiments of the present invention, the invention is not limited in above-mentioned embodiment, as long as it reaches the technique effect of the present invention with identical means, all should belong to protection scope of the present invention.Its technical scheme and/or embodiment can have various different modifications and variations within the scope of the present invention.
