ZigBee技术在智能交通信号灯控制中的应用研究

针对传统的定时切换交通信号控制模型已无法满足日益增长的交通需求，采用ZigBee无线传感器网络技术。设计一种智能控制信号灯系统，根据当前道路的实时情况，将采集的实时信息，通过ZigBee网络，发送到子控制模块。由子控制模块传输到主控制模块，主控制模块对数据进行处理，产生合理的交通信号灯动态配时方案，进行较为合理的道路管理，提高交通效率。实验结果证明该系统利用巨磁阻传感器和加速度传感器，结合对道路情况实时采集，通过ZigBee无线网络传送信息；设备之间通过无线网络连接，无需挖路布线，在智能交通领域具有一定的应用价值。

Research on Application of ZigBee Technology in Intelligent Traffic Signal Control

Aiming at the problem that Traditional timing switch control model of traffic signal has been unable to meet the growing traffic demand. By using the ZigBee wireless sensor network technology, an intelligent control signal system is designed in this paper, the system can send the real-time information it collects to the sub-control module in accordance with the real-time traffic situation by Zig- Bee network. Through the transmission from the sub-control module to the main control module, the main control module processes the data, develop a reasonable traffic light timing plan, and conduct a more rational road management, thereby, the transportation efficiency can be improved. Experimental results show that the system utilizes a giant magnetoresistive sensor and an acceleration sensor to transmit the real-time traffic situation it collects via ZigBee wireless network, the connection between devices over a wireless network, no needs to dig roads for cabling, this system can possess the application value in field of intelligence transportation.
