Abstract
The invention discloses an accurate positioning method of a wireless station terminal. The method is a method which can be displayed under a three-dimensional mode, and can fast, intuitively and accurately realize the accurate positioning of the wireless station terminal. The method can accurately position the accurate position of a suspicious wireless station terminal in a three-dimensional space, can play intuitive function in a decision level, increase the accuracy of decision, avoids the occurrence of wrong decisions and the like, is based on the existing resources and does not need extra labor or equipment.
Description
Technical field
The present invention relates to wireless terminal monitoring technology and GIS-Geographic Information System (GIS) field, particularly relate to a kind of wireless station terminal accurate positioning method.
Background technology
In recent years, Wireless Telecom Equipment becomes equipment indispensable in the people family.Meanwhile, phenomenons such as mobile phone, TV etc. are being got lines crossed, jitter take place often, and this is just more and more higher to the stability requirement of Wireless Telecom Equipment, have proposed very high requirement also for radio control department.
For the radio control industry, an important job is monitored exactly.Monitor suspicious terminal, search suspicious terminal; The suffered interfering frequency of radio station terminal that monitoring is set up is in accordance with the law searched interference source.And the final goal of monitoring is exactly the exact position of determining suspicious wireless station terminal or disturbing wireless station terminal.And search cycle is short more, to search accuracy high more, can satisfy people's demand more, more can less loss.
Present wireless station terminal localization method is based on two dimension, has following shortcoming or deficiency:
At first, this mode locate can only be accurate on the two dimensional surface certain a bit, can not accurately navigate in the space multistory face certain a bit.Under actual most of situation, wireless station terminal is not on the ground, as certain layer that can be in building.When certain one deck in building of wireless station terminal, the monitor staff need search the situation of each layer on certain a certain coordinate points of being determined by two dimensional wireless station terminal localization method, so not only waste resource, and can lose time, may cause unpredictable loss;
Secondly, two dimensional wireless station terminal localization method is showed not directly perceived.Treatment people, monitor staff or commanding etc. just rest on the two-dimentional aspect for the wireless station terminal position.
Summary of the invention
A kind of wireless station terminal accurate positioning method of the present invention aim to provide a kind of can under three dimensional pattern, show can fast, intuitively, accurately realize the pinpoint method of wireless station terminal.
The technical scheme of a kind of wireless station terminal accurate positioning method of the present invention is as follows:
The first step: after monitor terminal monitors suspicious wireless station terminal, the radio monitoring car utilizes the straightline propagation characteristic of radio wave, detect longitude and latitude, azimuth and the elevation information of signal source, monitor terminal is communicated by letter with Surveillance center by wireless network, described longitude and latitude, the elevation angle, azimuth and frequency information are transferred to Surveillance center, and described communication mode can insert with VPN network insertion, APN network insertion or APN+VPN mixture of networks mode;
Second step: monitor terminal is determined described suspicious wireless station terminal in the exact position in space in the three-dimension GIS map, regards two monitor terminals the end points of a ray as respectively, and the position of this end points is exactly the coordinate of monitoring terminal.According to the longitude and latitude that monitors, azimuth and the elevation angle, can draw one in the space respectively is the ray of end points with the monitor terminal, and the intersection point of ray is this suspicious wireless station terminal in three-dimensional exact position in described two three dimensions;
The 3rd step: monitor terminal will be described in the three-dimension GIS map definite described can wireless station terminal in the exact position in space relevant information and control centre's database matching;
The 4th step: will be described in the three-dimension GIS map definite described suspicious wireless station terminal after the exact position in space relevant information and control centre's database matching, if find that described suspicious wireless station terminal has data and legal in control centre, then described suspicious wireless station terminal is handled as the frequency conflicts wireless station terminal, if finding described suspicious wireless station terminal at control centre's non-avaible, then handles described suspicious wireless station terminal as the illegal wireless station terminal.
The beneficial effect of a kind of wireless station terminal accurate positioning method of the present invention is: described wireless station terminal accurate positioning method can accurately be located suspicious wireless station terminal in three-dimensional exact position; Described wireless station terminal accurate positioning method can be brought into play ocular effect on the decision-making level, increase the decision-making accuracy, avoid the making a strategic decision generation of phenomenons such as error, and, described wireless station terminal accurate positioning method is to be based upon on the basis of existing resource, does not need additionally to increase manpower or equipment.
Description of drawings
Fig. 1 is the flow chart of a kind of wireless station terminal accurate positioning method of the present invention.
Embodiment
Embodiment:
With certain city radio administration is example, in conjunction with the accompanying drawings, further specifies the embodiment of a kind of wireless station terminal accurate positioning method of the present invention.
Certain city radio administration is provided with various watch-dogs, and the existing station terminal in certain city is monitored in real time.Suspicious wireless station terminal of a monitor terminal discovery is being sent out and is being established signal near the A bridge, this monitor terminal is measured the parameter of the straightline propagation characteristic of radio wave immediately so, control centre will one based on the platform of three-dimension GIS on detecting the longitude and latitude of signal source, the azimuth and the elevation angle, determine the exact position of described suspicious wireless station terminal, and communicate by letter with monitor terminal by GPRS network control centre in conjunction with frequency information, the suspicious wireless station terminal information of measuring is passed to control centre, data in these data and the control centre's database are mated in control centre, if have and the relevant information of described suspicious wireless station terminal in control centre's database, and it is described that suspicious wireless station terminal is the wireless station terminal of legal use, judge so to have frequency conflicts, carry out frequency coordination.If do not have and the relevant information of described suspicious wireless station terminal in control centre's database, this terminal is judged to locate the illegal wireless station terminal so.
