Movable positioning system and method

Abstract

The invention relates to a mobile positioning system and a method thereof. The system communicates with telecom network and Zigbee wireless network between a positioning device and a positioning object, respectively receives the positioning signals of a globe positioning system, and adopts the telecom network to transmit their position information. The mobile positioning system and method combines GPS and the wireless positioning method based on Zigbee wireless network, wherein the positioning device is arranged at mobile type or distribution type to be used as the positioning reference point of a positioning object to obtain positioning reference data, and adopts positioning calculation to obtain the position of the positioning object. The invention overcomes the defects of GPS such as low positioning precision and high investment at special field; and resolves the problem that Zigbee positioning method needs to establish many positioning reference nodes and relative maintenance. The invention is suitable for positioning the positioning objects widely distributed or the network of strong mobility and randomness.

Description

technical field [0001] The invention belongs to the technical field of positioning, and relates to positioning devices for handheld and vehicle-mounted equipment, in particular to a mobile positioning system and method based on a global positioning system (GPS) and a Zigbee wireless network. Background technique [0002] In everyday life, we often need to determine the location of an object (such as emergency patients and young students, tools that need to be used, lost pets, etc.). For such a requirement, technically, the global positioning system GPS or location-based services (LBS, Location Based Services) are often used for positioning. However, sometimes, if the positions of the objects to be located are relatively concentrated and the number is relatively large, a wireless network (such as a wireless local area network) is often used for positioning. From the perspective of cost, the wireless local area network positioning method is smaller than GPS and LBS, but it ne...

Problems solved by technology

[0005] Aiming at the problems of high investment cost, low positioning accuracy, or inflexible use and relatively large investment in the existing technology, the purpose of the present invention is to meet various positioning requirements without establishing a fixed positioning reference node network, and adopts the The flexibility of the Global Positioning System (GPS) is combined with the higher precision of wireless network positioning. For this reason, the present invention provides a mobile positioning system and method based on the Global Positioning System (GPS) and the Zigbee wireless network.
