Embodiment

[0020] Such as figure 1 Shown, the present invention is based on the 2G network positioning system of base station positioning, comprises 2G module, also comprises the processor and analog switch that are connected on the 2G module, is connected with at least two groups of SIM card modules on the described analog switch; Said processor It is also connected with a display module and a database; the processor uses NXP S12X, the analog switch uses a TP0164 chip, the display module uses an LED display, and the database uses an SD card; this scheme uses LBS service to realize the positioning of the 2G network, because the LBS service is A positioning service based on communication base stations, which uses TOA, TDOA and AOA for positioning. Usually, the positioning accuracy of LBS services depends on the number of surrounding base stations, but when working in the field, the number of a single base station cannot be guaranteed, so , this solution adopts a multi-card method, which c...

Abstract

The invention discloses a 2G network positioning system based on base station positioning. The system comprises a 2G module and further comprises a processor and an analog switch which are connected with the 2G module, wherein the analog switch is connected with at least two SIM card modules. According to the scheme, 2G network positioning is realized by use of LBS, and since the LBS is positioning service based on communication base stations and realizes positioning by means of TOA, TDOA and AOA, the positioning precision of the LBS usually rests upon the quantity of surrounding base stations, yet the quantity of a certain individual base station cannot be guaranteed during field work, by use of a multi-card mode, the accuracy of field positioning can be improved by performing communication positioning with base stations of different communication providers. The system provided by the invention has the following advantages: the accuracy is high in areas without satellite coverage, and the system is improved based on existing equipment.

Description

technical field [0001] The invention relates to a 2G network-based positioning system, in particular to a 2G network positioning system based on base station positioning. Background technique [0002] The positioning system generally refers to the global positioning system. Simply put, this is a satellite system consisting of 24 satellites covering the globe. This system can ensure that at any time, any point on the earth can observe four satellites at the same time, so as to ensure that the satellite can collect the latitude, longitude and altitude of the observation point, so as to realize functions such as navigation, positioning, and timing. This technology can be used to guide aircraft, ships, vehicles, and individuals along selected routes safely and accurately to their destinations on time. In addition to the United States, there are also my country's independent Beidou satellite navigation system. Different from satellite positioning technology, base station posit...
