Embodiment Construction

[0022] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] The overall idea of ​​the present invention is to use the Beidou-based outdoor positioning scheme and the Zigbee-based indoor positioning scheme to realize the functions of indoor and outdoor vehicle driving navigation and parking positioning. The invention includes two positioning methods, namely: a Beidou satellite navigation and positioning method and a Zigbee-based indoor positioning method; the outdoor navigation module is mounted in the vehicle navigation, and the indoor positioning module is mounted on the indoor Zigbee positioning module receiver.

[0024] The object of the present invention is to provide an indoor and outdoor parking positioning system integrating Beidou satellite navigation and Zigbee technology, such as figure 1 As shown, including: an outdoor satellite Beidou positioning module, an indoor Zigbee positioning...

Abstract

The invention relates to an indoor and outdoor parking positioning system and method. An outdoor satellite positioning module is navigated by means of a Beidou satellite; an indoor Zigbee positioning module adopts ranging-based RSSI positioning algorithm for performing indoor positioning, Kalman filtering is utilized for performing optimizing processing on positioning data, and finally a geometric three-edge positioning algorithm is adopted for obtaining the indoor position of the indoor positioning module; an indoor and outdoor fusion switching module fuses, switches and integrates indoor and outdoor positioning modes based on a particle filter according to the intensity of indoor and outdoor positioning communication signals so as to achieve smooth transition of an indoor and outdoor positioning result; the positioning result adopts an outdoor two-dimensional electronic map and an indoor plane graph as the basis, a positioning result is displayed. The indoor and outdoor parking positioning system and method can be used indoors and outdoors, indoor application places can be large underground parking garages mainly, the system is low in complexity, the positioning precision can meet the requirement for automobile running navigation and parking positioning.

Description

technical field [0001] The invention relates to the technical field of indoor and outdoor vehicle parking location search and positioning services, in particular to an indoor and outdoor parking location system and a method thereof integrating Beidou satellite navigation and Zigbee technology. Background technique [0002] With the increasing maturity of global satellite positioning, navigation and positioning systems such as GPS, Beidou and GLONASS, people enjoy the fast and accurate positioning services brought by satellite positioning systems in outdoor activities. For the outdoor open environment, the Global Positioning System (GPS) is widely used, but in many indoor environments, due to the influence of the block of the cement wall, the satellite signal will be severely attenuated and cannot be realized in the indoor environment. Indoor positioning and navigation. [0003] In today's China, cars driving outdoors are increasingly inseparable from GPS or Beidou satellite...
