Detailed description of the invention
Below in conjunction with accompanying drawing, to the present invention, above-mentioned and other technical characteristic and advantage are clearly and completely described,
Obviously, described embodiment is only the section Example of the present invention rather than whole embodiment.
A kind of localization method based on the asset management system, comprises the steps: that label to be measured sends at set intervals
One heartbeat packet；The trunking being distributed in around label to be measured receives heartbeat packet and extracts the signal of label to be measured wherein
Intensity；Trunking is forwarded to server after being added in packet by signal intensity；Server is according to forwarding label signal to be measured
Trunking position and the signal intensity of label to be measured calculate the position of label to be measured, the position of the most some trunkings
It is known.
The signal that the signal intensity of label to be measured reads label to be measured transmission with actual range conversion by trunking is strong
Degree obtains RSSI value, during obtaining RSSI value, owing to existing with trunking itself containing labeling apparatus to be measured
The decay of signal, but its decay value unrelated with actual range, the present invention it is desirable that distance causes signal attenuation power situation,
So the RSSI value taken out must deduct the signal attenuation value containing labeling apparatus to be measured and trunking itself, then carrying out
Corresponding distance calculates；Change due to weather condition and air humidity can cause the change of signal intensity, due to all relayings
The most all keep off without body of wall lattice between the most already known position of equipment and trunking, so its RSSI is relative with distance relation stable
And true, therefore can take the signal intensity between two trunkings calculate weather condition at that time to the decay of signal or
Gain intensity, then calibrates in the RSSI value taken out accordingly.
In the examples below, B is label to be measured to be positioned, and Z is the trunking for label forwarding data to be measured
Or receiver apparatus.
Embodiment one
If as it is shown in figure 1, the quantity of the trunking forwarded is one, then treating according to the RSSI value of this trunking
The judgement of a distance is made in the position of mark label, and the position of label to be measured is with this trunking as the center of circle, with radius as RSSI
In any point of the circumference of value.Such as, the distance judged according to RSSI value is 5m, then can tag location to be measured be existed
Z1 equipment distance is in any point in 5m circumference range.
Embodiment two
If as in figure 2 it is shown, the quantity of the trunking forwarded is two, first come according to the RSSI value of Z1 equipment and Z2 equipment
The most how far determine two equipment of tag distances to be measured, be designated as a (Z1 equipment is to the distance of label to be measured) and b (Z2 equipment respectively
Distance to label to be measured), a <b in embodiment as shown in Figure 2, owing to the position of Z1 equipment and Z2 equipment is it is known that then can be straight
Connect and obtain Z1 equipment and distance c of Z2 equipment, then now can according to triangle angle formulae cosX=(a^2+c^2-b^2)/
(2 a c) calculates Z1 equipment to Devices to test with to the angle of Z2 equipment, from position determines B point or B ' point.
When the distance obtained by RSSI value is gone wrong, it is handled as follows:
When a+b < during c, a being described, among b, at least a value taken out is the least, but in actual use environment,
Typically it is only possible to occur that the distance ratio that RSSI value converts out is real apart from remote situation, then when this condition is met,
Then it is believed that to calculate point data close together more true (because point farther out is probably due to the reason such as through walls causes meter
The distance calculated is remote).
When a+c is < during b, because a <b, so explanation is that the value that b calculates is the biggest.Now the position of label to be measured
It is scheduled on B " this position.
Embodiment three
If as it is shown on figure 3, the quantity of trunking forwarded is three or more than three, then according to these three or three with
Upper trunking receives signal intensity to calculate RSSI value, specifically comprises the following steps that
Choose three trunkings that RSSI value is minimum；
Choose two trunkings, by calculating in these two trunkings the trunking of any one to label to be measured
Path and two trunkings directly receive the angle in path to determine the position of label to be measured；
Calculating residue trunking and determine the distance of label position to be measured to previous step, the nearer position of selected distance is
The position of final label to be measured.
The described residue trunking that calculates determines the distance of label position to be measured, the position that selected distance is nearer to previous step
In the step of the position being set to final label to be measured, further comprising the steps of:
When residue trunking to the distance determining label position to be measured is equal, then choose the little relaying of RSSI value the 4th
Equipment judges the final position of Devices to test.
As shown in figure 3 above, if the quantity of the trunking forwarded is three or more than three, first take out RSSI value minimum
Three equipment are analyzed, and choose Z1 equipment and RSSI value that Z2 equipment report comes up is to determine three equipment of tag distances respectively
How far, be designated as a (Z1 equipment is to the distance of label to be measured) respectively, (Z3 equipment arrives b (Z2 equipment is to the distance of label to be measured) and d
The distance of label to be measured), a <b < d in embodiment as shown in Figure 3, owing to the position of Z1 equipment and Z2 equipment is it is known that then can be straight
Connect and obtain Z1 equipment and distance c of Z2 equipment, can be according to triangle angle formulae cosX=(a^2+c^2-b^2)/(2 a c)
Calculate angle X (angle X is Z1 equipment to Devices to test with to the angle of Z2 equipment), from position being determined B point or B '
Point, now being fetched by the point of the 3rd equipment and being determined label is at B or at B ' on earth.
When the 3rd point is in Z3 point position, makes B point the same with the distance that B ' puts when, taking downwards RSSI value is
Four little trunkings judge.As the position Z3 ' of the 3rd point, d can be calculated according to coordinate B and coordinate Z3 ' " and
D ' " distance, which distance obtains out with the 3rd point and tag distances closer to, just use which point the most final
Coordinate.
When the distance obtained by RSSI value is gone wrong, it is handled as follows:
When a+b < during c, a being described, among b, at least a value taken out is the least, but in actual use environment,
Typically it is only possible to occur that the distance ratio that RSSI value converts out is real apart from remote situation.The most when this condition is met,
Then think that to calculate point data close together more true (because point farther out is probably due to the reason such as through walls causes calculating
Distance out is remote).
When a+c is < during b, because a <b, so explanation is that the value that b calculates is the biggest.Now we are the position of label
It is scheduled on B " this position.
As shown in Figure 4, if above-mentioned result of calculation is beyond actual monitored scope, in figure, the region drawn by solid line is by being monitored
Actual area, when coordinate position B ' position out, location is beyond physical location, tag coordinate position is slightly made to change by we
Dynamic, will from B ' point coordinates position B recently and in monitoring range " ' point is as the coordinate of label.
Particular embodiments described above, has been carried out further the purpose of the present invention, technical scheme and beneficial effect
Describe in detail, it will be appreciated that the foregoing is only the specific embodiment of the present invention, the protection being not intended to limit the present invention
Scope.Particularly point out, to those skilled in the art, all within the spirit and principles in the present invention, that is done any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
