Embodiment

[0075] First determine the area to be positioned, the positioning accuracy and the positioning method to be used, and then according to the positioning method and positioning accuracy requirements, establish a wireless micro-power communication network (the existing wireless communication network can also be used) to cover the entire positioning area. , the topology of the entire network can be diverse, star, tree, mesh and so on. In special cases, interval site coverage can also be used, such as fixed routes for public transport vehicles, personnel positioning points in coal mine underground tunnels, monitoring sites on expressways, etc. Each network node should establish a corresponding location mark, and the arrangement of network nodes should be consistent with the specific positioning method adopted.

[0076] Identify all moving targets in the network that need to be positioned, and install wireless micro-power transceivers. Generally, the settings of all wireless micro-p...

Abstract

The present invention relates to the positioning technology, in particular to a radio micropower network positioning technique and a positioning method. The prior positioning systems have the defects of complex structure, large investment and high operation cost, moreover, under complex environmental conditions, such as cities, the prior positioning systems cannot satisfy a lot of actual application requirements, and in order to resolve the defects, the present invention discloses the radio micropower network positioning technique and the positioning method. The present invention utilizes the positions of network nodes as references to determine the position of a mobile target according to the universal relation among signal sources, receivers, emissive power and signal intensity and the specific relation depending on the environmental characteristics. The present invention has the advantages of simple structure, low cost and mature technology, and complex measuring and calculation and electronic maps are not needed in order to satisfy the actual positioning requirement. The system is not only a positioning network but also a communication network which can transmit position information and control information, the structure is simplified, use is convenient, and the operation cost is greatly reduced.

Description

technical field [0001] The invention relates to a positioning technology, in particular to a wireless micropower network positioning technology and a positioning method thereof. Background technique [0002] So far, the positioning technology has all adopted the method of wireless signal positioning. Existing positioning systems can basically be divided into positioning systems represented by GPS and wireless network (including GSM and CDMA networks) positioning systems represented by mobile communication networks. [0003] GPS positioning technology [0004] The object to be positioned receives the positioning signals transmitted by four (at least three) GPS satellites at the same time through the connected GPS receiving terminal, and calculates the longitude, latitude and altitude coordinates (X, Y, Z) of the object to achieve positioning. This kind of X, Y, Z position coordinate information must be used in conjunction with electronic maps in general practical applicatio...
