It is standby.The present embodiment is wirelessly carried out data transmission using wifi using existing wireless deployed environment in building, saves network cloth
The trouble of line networking.
In the present embodiment, before the localization method for executing the asset equipment, the wireless access point is also needed to capture
To the launch channel of wireless signal matched with the working signal of the wireless access point.
Specifically, when disposing wireless access point 12, the working channel of wireless access point 12 is to preset, according to interference
The situation of channel minimum, can be set as 1 channel or 6 channels or 11 channels, and wireless location card can be according to certain frequency wheel
It askes in different channels, signal, the channel information contained in the data of transmitting is specifically emitted on 1-13 channel.When ap is received
To wireless location card emit data when, the working channel for itself matching wireless location card in its data is understood, if ap
Channel it is consistent with the channel of wireless location card, then retain data, otherwise abandon data.
Referring to Fig. 2, being shown as flow diagram of the localization method of asset equipment in an embodiment.As shown in Fig. 2,
The localization method of the asset equipment specifically includes following steps:
S21 receives the communication data of the wireless access point transmitting.
Whether S22 judges the quantity of the wireless access point more than three；If so, S23 is executed, if it is not, then executing
S23’。
S23, the intensity instruction (RSSI) that selection receives signal is more than three wireless access point of preset strength threshold value, and turns
Enter step S24.Selected three wireless access point APs form triangle.
S24 carries out initial decision to the position of the asset equipment according to the position coordinates of the wireless access point, with
Obtain the initial position of the asset equipment.
Specifically incorporated by reference to the initial position schematic diagram of triangulation location asset equipment shown in Fig. 3, the S24 is retouched in detail
It states.
The setting of the initial position of asset equipment is defined as unknown point E, and by unknown point E and three wireless access point
The position coordinates of BS1, BS2, BS3 are respectively (x1, y1), and (x2, y2), (x3, y3) is associated.
Specific association process are as follows:
According to distance r1, the r2 of unknown point E to three wireless access point BS1, BS2, BS3, r3 is that radius does three circles.
According to interrelational form is prestored, the initial position of the asset equipment is obtained.
It is described to prestore interrelational form are as follows:
(x1-x)2+(y1-y)2=r12
(x2-x)2+(y2-y)2=r22Formula (1)
(x3-x)2+(y3-y)2=r32
In the present embodiment, pass through the incidence relation according to unknown point E to three wireless access point BS1, BS2, BS3, meter
Calculate the initial position of unknown point.But because the data that obtain of the interference and test of environment there are error, it is all further
Judge in conjunction with fingerprint base Data Matching.
S23 ', if whether the quantity of the wireless access point more than three, i.e., the quantity of the described wireless access point is 2
When, the intensity that selection receives signal indicates the position coordinates of higher wireless access point, the initial bit as the asset equipment
It sets, and is transferred to S25.

Cross the RSSI sample data that a mobile terminal is arrived in a certain reference point (x, y) through sampled acquisition after a period of time.
In real-time positioning stage, how reference data set gathered in advance at the reference point obtained in real time is referred to prestoring
RSSI data sample in line database is matched.
In the present embodiment, using nearest-neighbors method by the wireless access point obtained in real time reception signal intensity
It indicates that the sample data concentrated with reference data gathered in advance at several reference points is matched, and selects matching degree highest
Reference point final position of the position as the asset equipment.
The nearest-neighbors method are as follows:
Wherein, d indicates matching degree, and n is the quantity of wireless access point, and i indicates the number of wireless access point,For
One reference point (xi, yi) through preparatory collected RSSI sample data after a period of time, RSSIiFor in a reference point (xi, yi) real
When collected RSSI sample data, p is that distance calculates selection parameter.
As parameter p=1, calculating is manhatton distance, is Euclidean distance when p=2, the present embodiment selection it is European away from
With a distance between calculating signal strength.The position that nearest-neighbors method the obtains necessarily already existing reference in fingerprint database
Point position.K-nearest neighbor (K-NNSS) is a kind of modified version of nearest-neighbors method, it is no longer simply using in signal space
Apart from nearest point as location estimation, but the position of user is estimated using the average value of the nearest several sampled points of distance
It sets.
S26, after S25 matching, the final position for the asset equipment that will acquire is converted to be built relative to described
