摘 要：
针对传统农田气象信息远程传输方式中布线难、成本高、传输距离有限、入网许可限制等不足,以广泛覆盖的GSM无线网络为基础,提出了一种实现远程农田气象信息采集、传输和监控的技术方案。详细讨论了实现该方案的系统结构模型、工作原理,给出了系统相应的软硬件设计方案,并定义了一种应用层通信协议,以实现系统中各类参数信息、控制信息的有效传输和识别,减小信息阻塞现象。实验表明,该方案系统结构模型合理,软硬件设计可行,具有灵活的扩充性和伸缩性,系统通信成功率为93.3%,可以满足农田气象信息远程监控的实际需要。

摘 要：
On the basis of GSM with strong coverage power,a scheme,which can implement remote collection,transmission,and monitoring of farm field meteorological information,was presented to solve some problems,such as routing difficulty,high cost,distance limitation and restricted network access permission.Its structure and working principle were described in detail,and the software and hardware design was given.Furthermore,a type of application layer protocol,which will be useful for reducing congestion,was defined for more efficient transmission control and data recognition.The experimental results show that the proposed scheme is effective and efficient,and the given software and hardware design is feasible.The established remote monitoring system is flexible to be extended or reduced,and its communication success rate is 93.3%,which can fulfill the actual demand for remote monitoring of farm field meteorological information.
