Embodiment Construction

[0028] An indoor and outdoor seamless positioning system based on the combination of Beidou navigation and UWB technology, such as figure 1 As shown, it includes Beidou reference station subsystem, data processing center subsystem, Beidou / UWB mobile station subsystem, indoor UWB positioning subsystem, and system monitoring subsystem.

[0029] Beidou reference station subsystem equipment mainly includes Beidou reference station receiver, Beidou antenna and power supply module. The Beidou reference station receiver uses a high-precision Beidou receiver; the power module converts the 220V AC mains power into a regulated DC power supply to supply power to the Beidou reference station receiver. The antenna of the Beidou base station is installed in an open place, such as the roof of the terminal office building. During installation, it should be ensured that there are no high obstructions and electromagnetic interference sources that affect the normal operation of the Beidou withi...

Abstract

The present invention discloses an indoor / outdoor seamless positioning system and method. The seamless positioning system comprises a data processing center sub-system, and a Beidou reference station sub-system, an indoor ultra wide band (UWB) positioning sub-system, a Beidou / UWB mobile station sub-system and a system monitoring sub-system which are connected with the data processing center sub-system separately. The data processing center sub-system sends the current position coordinate of a working device which is determined by the Beidou positioning and the UWB positioning to the system monitoring sub-system to display visually, at the same time, calculates the spatial position relation of the working device, the inlet identification point, an outlet identification point and a switching determination identification area according to the current position coordinate of the working device, thereby realizing the bidirectional adaptive switching of the indoor / outdoor combined positioning. Compared with the prior art, the positive effects of the present invention are that by the fusion of the Beidou navigation positioning and a UWB real-time positioning system, the continuous positioning of the indoor / outdoor mechanical devices is realized, thereby realizing the uninterrupted positioning and monitoring of the mechanical devices.

Description

technical field [0001] The invention relates to an indoor and outdoor seamless positioning system and method combining Beidou navigation and UWB (Ultra Wideband) technology. Background technique [0002] In recent years, the demand for indoor and outdoor seamless positioning technology has been increasing in the market. With the development of indoor positioning in shopping malls and driverless cars, the market for seamless indoor and outdoor positioning will explode. The indoor and outdoor positioning technology solves the shortcomings of Beidou navigation positioning, RFID positioning, Zigbee positioning, etc., which can only be used for indoor or outdoor positioning technologies, and combines several of them into an organic whole, which can be applied to various environmental scenarios. For bulk cargo terminals, there is a need for high-precision continuous positioning of operating equipment indoors and outdoors. [0003] The Beidou Navigation Satellites System (BDS) is...
