Embodiment Construction

[0056] The present invention will be further explained below with reference to the drawings and embodiments.

[0057] figure 1 It is a system block diagram of the first embodiment of the indoor and outdoor positioning system of the present invention, such as figure 1 As shown, in this embodiment, the indoor and outdoor positioning system 100 of the present invention includes: a portable device 110, a receiving positioning device 120, and a terminal server 130.

[0058] The portable device 110 is set on a fixed or mobile identifier in the current building (for example, a table, a cabinet, or a person in the building), and is used to transmit radio frequency signals. In this embodiment, the portable device 110 is active, and the transmitted radio frequency signal is a radio frequency signal of 800 KHz to 1.5 MHz.

[0059] The receiving positioning device 120 includes a database, and the database includes indoor map information of the current building. The receiving and positioning dev...

Abstract

The invention discloses an indoor and outdoor positioning system and a positioning method thereof. The system comprises a portable device, a receiving positioning device and a terminal server. The method comprises the steps that firstly, the portable device arranged on a marker inside a building sends a radio frequency signal; secondly, the receiving positioning device arranged outside the building receives the radio frequency signal, and the coordinates, in an indoor map of the current building, of the portable device are calculated according to the radio frequency signal; thirdly, the indoor map of the current building and an outdoor map, measured by the GPS or the Beidou Satellite, of the current building are called through the terminal server, and the coordinates in the indoor map are converted into the coordinates in the outdoor map according to the proportional relation between the indoor map and the outdoor map of the current building. According to the system and method, the blocking of metal and barriers can be well overcome by utilizing the low-frequency radio frequency technology, the positioning precision is high, deployment can be fast achieved, and the system can adapt to various severe environments.

Description

Technical field [0001] The present invention relates to wireless positioning technology, and more specifically, to an indoor and outdoor positioning system and a positioning method thereof. Background technique [0002] Location-based service (LBS: LocationBasedService) is a field of electronic information industry with wide application and huge market value. The current indoor or outdoor positioning systems include the following: [0003] 1. GPS positioning [0004] The Global Positioning System (GPS) is a new generation of space satellite navigation and positioning system jointly developed by the United States Army, Navy and Air Force in the 1970s. Its main purpose is to provide real-time, all-weather and global navigation services for land, sea and air, and for military purposes such as intelligence collection, nuclear explosion monitoring, and emergency communications. It is mainly composed of 24 dedicated GPS satellites. Combined with ground-based auxiliary equipment, the civi...
