摘　　要：单个ZigBee网络往往只有一个网关.单网关系统可能存在一些问题,如大数据量造成网络延时,网关节点坏掉使整个网络瘫痪等.为解决这些问题,提出了一种在单个ZigBee网络中设置多个网关的设计方法.将网络中所有传给单个网关的数据分成几部分分别传送给多个网关,各网关将数据进行转换后传输到以太网,PC端服务器通过TCP/IP协议汇总网关数据后集中处理.介绍了多网关系统的组成和工作原理,完成了系统软硬件设计,并详细描述了路由对最佳网关的选择过程,最后对系统进行了测试.测试结果表明,该多网关系统运行稳定,能有效弥补单网关ZigBee网络的不足.Single ZigBee network usually has only one single gateway. Single gateway system may have some problems, for example, network time delay caused by the large amount of data, and paralysis of the whole network due to the dysfunction of one gateway node. In order to solve these problems, the design method of multiple gateways in a single ZigBee network is proposed. Firstly, Data sending to the single gateway are divided into several parts and sent to multiple gateways. Then, gateways convert the received data and transmit them to the Ethernet. PC server gathers data via TCP/IP protocol and processes them eventually. The architecture and working principle of the designed multi-gateway system are introduced first. The hardware and software designs of the system are presented, and the route selection process for the best gateway is described in details. The final testing results indicate that the multi-gateway system works stably and can make up the deficiency of the single gateway ZigBee network effectively.
