Embodiment Construction
[0053] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0054] The indoor and outdoor positioning system for interconnecting UWB and smart phones of the present invention includes a base station sub-system, a label sub-system, a data processing sub-system, a mobile phone client APP, and a smart phone.
[0055] The base station subsystem is composed of several base stations, the base stations are fixed at different indoor positions, and at least four base stations need to be fixed for each independent indoor target area.
[0056] The label subsystem is composed of several mobile labels, and the mobile labels are set on each target user.
[0057] like figure 1 As shown, the base station includes a Cortex-M4 chip, a base station DWM1000 module, a base station serial port module, an LED indicator, and an Ethernet module. When the base station is working, power is supplied through the base station serial...

Abstract
The invention discloses an indoor and outdoor positioning system and method based on UWB and smart phone interconnection. The UWB positioning system comprises a base station subsystem, a label subsystem, a data processing subsystem, upper computer software, a mobile phone client APP and a smart phone. A UWB technology, an INS and a GPS system of the smart phone are used for achieving dynamic accurate positioning of a target user in indoor and outdoor different environments and complete data acquisition. The positioning system and method is mainly applied to the internet-of-things industry, thetourism industry, the commercial places, the airports, the fire fighting, the public security, the military affairs, the parking lots, the hospitals, the robots, the unmanned aerial vehicles, the tunnel mines and the like.
Description
technical field [0001] The invention relates to a wireless indoor and outdoor positioning technology, in particular to an indoor and outdoor positioning system and method for interconnecting UWB and a smart phone, and belongs to the field of electronic information technology. Background technique [0002] With the development of social needs, many industries also put forward urgent needs for indoor positioning technology, such as the Internet of Things industry, tourism industry, commercial places, airports, fire protection, public security, military, parking lots, hospitals, robots, drones, tunnels mines etc. At present, although there are various solutions for indoor positioning, such as WIFI positioning, ultrasonic positioning, Bluetooth positioning, geomagnetic positioning, satellite positioning, radio frequency identification, infrared positioning, Zigbee positioning, etc., but due to technical limitations and cost issues, there is no solution like GNSS positioning. Th...
