Positioning system based on CC2530 technology and ZigBee technology and achieving method thereof

Abstract

The invention discloses a positioning system based on the CC2530 technology and the ZigBee technology and an achieving method thereof. The positioning system comprises a ZigBee wireless network unit based on a Z-Stack protocol stack, a wireless terminal, a module to be positioned and a power source, wherein the wireless terminal and the module to be positioned are respectively connected with the ZigBee wireless network unit, and the power source is connected with the module to be positioned. The wireless terminal obtains corresponding information of the module to be positioned through the ZigBee wireless network unit and conducts calculation based on the corresponding obtained information to obtain positional information of the module to be positioned. According to the positioning system based on the CC2530 technology and the ZigBee technology and the achieving method, the defects, such as low accuracy, large influences by reference node density and distribution and large influences by error accumulation, in the prior art can be overcome, and therefore the advantages of high accuracy, small influences by the reference node density and distribution and small influences by the error accumulation can be achieved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a positioning system based on CC2530 and ZigBee technology and an implementation method thereof. Background technique [0002] ZigBee is a short-range wireless communication network protocol with low data rate and low power consumption. It is suitable for industrial control and sensor networks. It was established and proposed by the ZigBee Alliance in 2002. It accepts the IEEE802.15.4 protocol as the PHY layer of the protocol and MAC layer. The ZigBee protocol works at 868MHz, 915MHz and 2.4GHz, of which 2.4GHz is a global license-free frequency band, with a maximum data transmission rate of 250kbps, supports star, mesh, tree and other network structures, and supports ad hoc networks. [0003] The CC2530 produced by TI is a system-on-chip solution for ZigBee, which integrates a high-performance RF transceiver and a 51-core baseband processor; in addition, it also i...
