摘要
为了解决野外多点数据采集无供电、布线复杂和通信困难的问题,提出了一种基于"北斗一代"的Zigbee无线网关设计方案。采用MSP430F6438、CC2341微处理器和一体化的RDSS"北斗"射频芯片完成低功耗、小成本的硬件设计。通过增加SIM卡的数量,将网关转发"北斗"数据的频率降至最低的5 s,提高了网关的通信速率。通过软件设计实现了Zigbee无线传感网络和"北斗一代"系统之间数据的透明交换。该方法已成功应用于野外油气井远程监控系统中。
Based on Beidou first generation, a Zigbee wireless gateway design scheme is proposed to deal with problems of outdoor data collecting, such as no power supply, complicated cabling and difficult communicating. This scheme uses MSP430F6438, CC2431, RDSS RF chip and so on, to design a gateway hardware with low cost and power consumption. By increasing the number of SIM cards, the gateway forwarding Beidou data frequency is reduced to 5 seconds, thus enhancing the data transmission rate of the gateway. This gateway can transparently convert the data between the Zigbee wireless sensor network and Beidou communications systems by using software design. This method has been successfully deployed in field oil and gas well remote monitoring system.
