摘 要
随着传感器、无线通信、嵌入式系统等技术的发展，在宽带移动通信、下一代网络和云计算等技术的支撑下，物联网己经广泛应用在仓储物流、智能电网、公共安防、智能楼宇等领域，因其巨大的应用前景得到各国政府的重视，视为继计算机互联网与移动通信网络之后的第三次信息化浪潮。作为连接感知网络与传统通信网络/互联网的桥梁，物联网网关在物联网应用中起到极为重要的角色，在网络架构上有利于现有的通信网络/互联网与感知网络的无缝融合，在应用模式上有利于对传感器网络和感知节点的管理和控制。结合物联网典型应用场景和电信运营商的应用需求，提出了一个基于ZigBee/GPRS的物联网网关系统，实现了传感网与电信网络之间的数据传送、不同类型
感知网络之间的协议转换，以及对传感器网络的部分管理控制功能。最后，给出原型系统的实现技术和系统验证。
本文首先介绍了ZigBee , GPRS技术的概念及其协议架构，然后介绍了ZigBee-GPRS网关的设计与实现、远程无线传感器网络节点的硬件及其软件的设计方法，进而完成ZigBee与GPRS融合组网。ZigBee传感器节点采用CC2530作为无线数据收发芯片。GPRS模块采用ComWay模块。用户通过操作终端进行远程测控，可获取ZigBee无线传感器网络内部各节点的传感信息。与类似系统相比，本系统实现简单，功能完善，具备实际推广价值。文中最后对本无线传感器网络进行了测试，试验表明所研发的无线传感器网络具有较好的远程监测性、扩展性和移植性，可实现远程无线传感监测功能。 关键词：物联网 无线传感网 ZigBee 以太网 GPRS

(College of Engineering, South China Agricultural University, Guangzhou 510642, China) Abstract:Under the support of broadband mobile communication. Next generation network and cloud computing. Internet of Things(IOT) has been widely used in warehouses,SmartGrids,
public security, intelligent buildings and so with the development of sensors, wireless communication and embedded systems. Because of its huge prospect in public applications, Internet of Things has been paid special attention by governments all over the world, viewed as the third wave of information technology following Internet and mobile network. As the bridge between sensor network and traditional communication network/Internet, IOT gateway plays an important role in IOT applications. IOT gateway is used for seamless integration of sensor networks and Internet/telecommunication networks,also facilitates the control and management of sensor networks and sensor nodes. In this paper, we propose an IOT gateway system based on ZigBee and GPRS protocols according to the typical networking scenarios and application requirements of telecom operators;enable the data transmission between sensor networks and telecommunications network, protocol conversion of different sensor network protocols and some control functions of sensor network;and finally give the implementation details of the prototype system and performance evaluation.
This paper firstly introduces the concept and the framework agreement, of ZigBee and GPRS technology,and then introduces ZigBee-GPRS gateway's design and implementation,and remote wireless sensor network node of the hardware and the method of software design,after that accomplish ZigBee and GPRS fusion networking. The node of ZigBee sensor uses CC2530 as a wireless data transceiver chip. GPRS module uses ComWay module. The user can remote control via terminal operation, and then it can obtain the sensor information of each interna node of ZigBee wireless sensor network. Compared with a similar system, this system has the simple implementation and strong maneuverability and perfect function and the actual value of popularization. The final test shows that the wireless sensor network has very good remote monitoring sex, scalability, and portability, Which enables remote monitoring wireless sensor.
