针对基于现场总线技术的数据采集系统线路铺设受限以及依托GSM网络的无线数据采集系统数据有延时现象、成本较高等问题,介绍了基于ARM-Linux的嵌入式远程数据采集系统,提出将嵌入式Internet和无线网络相结合应用在农田信息采集中的做法,给出了系统硬件结构和软件设计,重点研究了移植Boa作为Web服务器的过程以及动态Web技术的实现。本系统能够对较大范围内农田数据进行有效采集,具备良好的稳定性和扩展性。
In order to solve the problems that the data acquisition system based on field bus is limited in laying lines and the delay of data in wireless data acquisition system relying on GSM network, the cost is high, an embedded remote data acquisition system based on ARM-Linux is introduced. Style Internet and wireless network in farmland information collection. The system hardware structure and software design are given. The process of transplanting Boa as Web server and the realization of dynamic Web technology are emphatically studied. The system can effectively collect farmland data in a wide range and has good stability and expansibility.
