Abstract
The invention discloses a kind of 2G network positioning system based on base station location, including 2G module, further include the processor and analog switch being connected in 2G module, minimum two groups of SIM card modules are connected on the analog switch；This programme realizes the positioning of 2G network using LBS service, since LBS service is a kind of positioning service based on communication base station, it is positioned using the means of TOA, TDOA and AOA, the positioning accuracy of LBS service depends on the quantity of peripheral base station under normal conditions, but in field work, some independent base station number not can guarantee, therefore, this programme can increase the accuracy of field positioning by carrying out communication positioning from the base station of different communication providers by the way of blocking more.The invention has the advantages that high in the regional accuracy that satellite does not cover；It is improved based on existing equipment.
Description
Technical field
The present invention relates to a kind of positioning systems based on 2G network, and in particular to the 2G network positions system based on base station location
System.
Background technique
Positioning system refers generally to global positioning system.Briefly, this is one and is made of 24 satellites covering the whole world
Satellite system.This system can guarantee that at any time any point can observe 4 satellites simultaneously on the earth,
To guarantee that satellite can collect the longitude and latitude and height of the observation point, to realize the functions such as navigation, positioning, time service.This
Technology can be used to vector aircraft, ship, vehicle and individual, safely and accurately along selected route, reaching on the time purpose
Ground.There are also the autonomous Beidou satellite navigation systems etc. in China in addition to the U.S..It is different from satellite positioning tech, base station location is generally answered
For mobile phone user, cellular base station positioning service, which is called, does mobile location-based service, it is the network by telecommunications mobile operator
The location information for obtaining mobile terminal user provides respective service under the support of electronic map platform for user.
Sometimes when field carries out the task of high level security, since GPS positioning rests in U.S.'s hand, in order to avoid letting out
It is close, satellite positioning will not be generally used, and traditional dependence Orientation on map efficiency is lower, precision is lower.
Summary of the invention
The technical problem to be solved by the present invention is to sometimes field carry out high level security task when, due to GPS positioning
Rest in U.S.'s hand, in order to avoid divulging a secret, will not generally use satellite positioning, and it is traditional by Orientation on map efficiency compared with
Low, precision is lower, and it is an object of the present invention to provide the 2G network positioning system based on base station location, solves to carry out high secrecy in field sometimes
When the task of degree, since GPS positioning rests in U.S.'s hand, in order to avoid divulging a secret, satellite positioning will not be generally used, and it is traditional
By Orientation on map again efficiency it is lower, the lower problem of precision.
The present invention is achieved through the following technical solutions:
2G network positioning system based on base station location, including 2G module further include the processor being connected in 2G module
And analog switch, minimum two groups of SIM card modules are connected on the analog switch；
Processor: receiving the location information that 2G module is sent, and stores location information；
SIM card module: SIM card information is sent to 2G module by analog switch；
Analog switch: receiving control signal, according to the control corresponding SIM card module of signal conduction.This programme is taken using LBS
The positioning of pragmatic existing 2G network, since LBS service is a kind of positioning service based on communication base station, using TOA, TDOA and AOA
Means positioned, the positioning accuracy of LBS service depends on the quantity of peripheral base station under normal conditions, but in field work
When, some independent base station number not can guarantee, therefore, this programme by the way of blocking more, can by from different communication
The base station of supplier carries out communication positioning to increase the accuracy of field positioning.
The processor is also connect with analog switch.After processor completes primary positioning, that is, control signal occurs to mould
Quasi- switch, control analog switch switch SIM card module.
Database is also connected on the processor.When SIM card module is more in system, processor cache pressure compared with
Greatly, location information is stored using database secondary processor, while can also pre- typing cartographic information.
Display module is also connected on the processor.The location information that processor stores is shown by display module
Show.
Invention compared with prior art, has the following advantages and benefits:
1, the present invention is based on the 2G network positioning systems of base station location is covered not using the method for base station location in satellite
The regional accuracy arrived is high；
2, it the present invention is based on the 2G network positioning system of base station location, is improved based on existing equipment, improving cost
It is low.
Detailed description of the invention
Attached drawing described herein is used to provide to further understand the embodiment of the present invention, constitutes one of the application
Point, do not constitute the restriction to the embodiment of the present invention.In the accompanying drawings:
Fig. 1 is present system structural schematic diagram.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below with reference to embodiment and attached drawing, to this
Invention is described in further detail, and exemplary embodiment of the invention and its explanation for explaining only the invention, are not made
For limitation of the invention.
Embodiment
As shown in Figure 1, the present invention is based on the 2G network positioning system of base station location, including 2G module, it further include being connected to
Processor and analog switch in 2G module are connected with minimum two groups of SIM card modules on the analog switch；On the processor
It is also connected with display module, database；The processor uses NXP S12X, and analog switch uses TP0164 chip, shows mould
Block uses LED display, and database uses SD card；This programme realizes the positioning of 2G network using LBS service, due to LBS service
It is a kind of positioning service based on communication base station, is positioned using the means of TOA, TDOA and AOA, LBS takes under normal conditions
The positioning accuracy of business depends on the quantity of peripheral base station, but in field work, some independent base station number not can guarantee,
Therefore, this programme can be increased more by the way of blocking by carrying out communication positioning from the base station of different communication providers
The accuracy of field positioning.The processor is also connect with analog switch.After processor completes primary positioning, that is, control
Signal controls analog switch and switches SIM card module to analog switch.Database is also connected on the processor.When in system
When SIM card module is more, processor cache pressure is larger, stores location information using database secondary processor, while may be used also
With pre- typing cartographic information.The location information that processor stores is shown by display module.
Processor: receiving the location information that 2G module is sent, and stores location information；
SIM card module: SIM card information is sent to 2G module by analog switch；
Analog switch: receiving control signal, according to the control corresponding SIM card module of signal conduction.
Above-described specific embodiment has carried out further the purpose of the present invention, technical scheme and beneficial effects
It is described in detail, it should be understood that being not intended to limit the present invention the foregoing is merely a specific embodiment of the invention
Protection scope, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should all include
