Embodiment Construction

[0019] In the current positioning terminal, one positioning method is often used for positioning, and it is impossible to support multiple positioning methods and perform self-adaptation of the positioning terminal.

[0020] The positioning terminal adopts the method of bus, which can support various existing positioning methods, and can support possible positioning methods in the future, without redesigning and developing the hardware.

[0021] The positioning terminal includes:

[0022] (1) Positioning system adapter

[0023] Design and develop the adapter of the existing positioning system, so that different positioning systems have a unified data interface and control interface. The positioning system adapter is connected to the positioning data bus.

[0024] (2) Positioning data bus

[0025] In order to ensure that the positioning terminal has the ability to expand to different positioning systems and the control and communication capabilities of multiple positioning s...

Abstract

The invention provides a positioning terminal combining multiple positioning methods, which self-adaptively selects positioning methods according to different positioning requirements and positioning environments. The positioning terminal comprises a positioning system adapter, a positioning data bus, a positioning bus controller, a communication data bus, a communication module adapter and a communication bus controller. Multiple positioning methods can be adopted through the positioning terminal of the invention, and under the condition without GPS positioning or Beidou satellite positioning and wireless communication assisted positioning, the positioning terminal still can complete positioning according to other positioning modes, thereby overcoming the limitation caused by the single positioning method of the traditional positioning terminal.

Description

technical field [0001] The invention relates to the field of terminal positioning, in particular to a positioning terminal device combined with multiple positioning methods. Background technique [0002] The application of satellite navigation and positioning technology in China has changed from the isolated use of satellite navigation system positioning, timing and other capabilities (its application is mainly in the form of using satellite navigation receiver alone) to integrated satellite navigation, mobile communication, computer, Internet, geographic information, etc. Mobile target positioning, management and information services of systems and other technologies. my country has also established distinctive positioning systems based on conventional radio stations (VHF / UHF), trunking communication systems, cellular systems (GSM, CDPD) and satellite systems. [0003] At present, the positioning system of moving targets is a research hotspot. In the context of my country'...
