Design of Removable Guardrail System Based on ZigBee Network

Abstract

In order to solve the problem that tidal phenomena will lead to severe traffic jam, this paper designs a Removable Guardrail System based on ZigBee network (RGSZ). This system includes the user terminal device and the removable guardrail device. The user terminal selects CC2530 which supports ZigBee protocol as wireless transmission module. It sends moving instructions from user terminal to nearest guardrail device. The removable guardrail device selects MSP430 as the controller to receive moving instructions from user terminal, then driver chip will drive stepping motor to move. At the same time CC2530 sends moving instructions to next guardrail device through ZigBee, making all guardrail devices moving together. By remote controlling removable guardrails to change the width of the road on both sides, this system makes road more humanized and improves the traffic jam greatly. The result of experiment tests indicates that: the system has the characteristics of runs stably, high precision and safe information transmission.
