| Abstract: | In order to realize the intelligent bus management system,a bus system which is based on ZigBee technology and use a CC2530 chip of Texas Instruments Company is designed. Proposed a positioning technology which is based on Received Signal Strength Indication and proposed three kinds of algorithm to improve the positioning accuracy. Besides, this paper analyzed the working principles of the intelligent bus management system,the hardware components and the sotware workflow. The experiment turns out that the system can realize some functions which include the positioning of the bus, automatic broadcast the information when the bus reach the bus station and some specific location, the system can realize the intellectualized management of the bus system. |
