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 invention relates to positioning technology, in particular to a wireless micropower network positioning system and a positioning method thereof. The invention overcomes the defects that the conventional positioning system has complex structure, high investment and high running cost, and cannot meet the requirements of various kinds of practical application under complex environment conditions such as cities and the like, and discloses the wireless micropower network positioning system and the positioning method thereof. The position of a moving target is determined by taking the position of a network node as a reference according to the general relationship among a signal source, a receiver, transmitting power and signal intensity in a positioning area and the specific relationship depending on environmental characteristics. The positioning system has the advantages of simple structure, low cost, mature technology, no need of complex measurement and calculation, and no need of an electronic map to meet the requirements of practical application; and the positioning system is a positioning network, and is also a communication network capable of transmitting position information and control information, so that the structure of the system is simplified, the system is convenient to use, and the running cost is greatly reduced.

Description

[0001] This application is a divisional application of the Chinese invention application with the application number 200610022177.7, the application date is November 2, 2006, and the invention name is "Wireless Micropower Network Positioning System and Its Positioning Method". technical field [0002] The invention relates to a positioning technology, in particular to a wireless micropower network positioning technology and a positioning method thereof. Background technique [0003] 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. [0004] GPS positioning technology: [0005] The object to be positioned receives the positioning signals transmitted by four (at least three) GPS satellites at the same time through the...
