Mobile space four dimensional information service system and terminals thereof and location method

Abstract

The invention discloses a mobile space four dimensional information service system and terminals thereof and a location method. Application terminals are developed based on the service system; indoor and outdoor acquisition of four dimensional information of one's own side and four dimensional information of an opposite side can be carried out by users; tracking, storing, processing and transmission of user information can be carried out by the service system; Beidou satellite navigation systems having all three features such as positioning, timing and short message transmission are utilized by service system terminals in a great outdoor range, and Beidou / GPS double correction technologies are adopted by the service system terminals to acquire positioning and timing information of one's own side and the opposite side; regional wireless location technology is adopted at relatively weak satellite signal regions, and three dimensional location problems are solved by combining data integrated technologies, a regional localization algorithm and a wireless sensor network multi-hop relay algorithm. An embodiment of the invention is applicable to conditions that many people are at a large region and both management staff and users themselves are required to know very well about position information; the embodiment of the invention is applicable to large stadiums and gymnasiums to guide the audience to take seats and maintain order at a scene to ensure a smooth game.

Description

technical field [0001] The invention relates to a comprehensive positioning method and a space information service system, which combines radio frequency, satellite positioning and digital geographic technology. It specifically relates to a mobile space four-dimensional information service system and its terminal equipment and positioning method, which can not only perform accurate positioning outdoors, but also obtain accurate three-dimensional positioning information indoors, and can also be monitored by the service control center and obtained by the service control center. The information sent by the mobile space information service platform belongs to the technical field of wireless communication. Background technique [0002] According to statistics, 80% of the various information in human production and life is related to geographic space location. By making full use of digital information and communication network technology, we can build a platform using digital info...

Problems solved by technology

[0006] At present, there is no mobile spatial information service in the strict sense, but there are already some technologies and products that can provide related services, such as vehicle navigation equipment, or technologies such as navigation and information query using mobile smart and communication devices such as PDAs and mobile phones. These technologies are not perfect in terms of positioning, and there are few spatial information service functions that can be realized. They also do not involve the technical scheme of dual-star mutual calibration and the technology combined with other wireless positioning methods. These are all problems to be solved
