摘要
针对传统农田气象信息远程监控系统采集机构布线难、成本高、传输距离有限等不足,提出利用GSM网络覆盖范围广、价格低廉等优势设计的无线网络采集节点方案,阐述无线网络采集节点的硬件构成、通信原理和具体实现方法。实验表明,该设计方案合理可行,能实现农田气象信息的定时采集、稳定传输和实时报警。
Aiming at the problems existing in collection part of traditional farm field meteorological information remote monitoring system, such as difficult routing, high cost and distance limitation, this paper presents a scheme of wireless network collection node based on GSM with its wide covering, rapid and low price, and describes hardware architecture, communication principle and software implementation. The experiment shows that the system is reasonable and feasible, it can realize timely collection, stable transmission and real-time alarm of farm field meteorological information.
