Abstract

Water volumes for agriculture copes with the water scarcity (drought), which is a big problem for this sector. Agrarian Exploitations are introducing new Irrigation Systems with high technologies to prevent this problem, especially in the Mediterranean Region. An Irrigation System consists of several elements: aquifers, water pumps, a hydraulic network (pipes) and a great number of electro-values, which are far from the central post (in the order of km). to control the whole system is necessary to operate remotely every electro-value, which requires simultaneously control information (to open/close these electro-values) and power. The only way to operate with the lowest cost, is using a single wire for both, control and power. In this paper is shown a specific communication study for wide Irrigation Systems with Integrated Power Transmission, to carry out data communications over 2/spl times/1.5 mm section wires and distances no longer than 10 km, under very restrictive current consumption requirements, using OOK (On-Off Keying) modulation and a suitable filter design, both for transmission and reception.

综合动力传输的广域灌溉系统的具体通信研究

农业用水量应对水资源短缺(干旱)，这是该部门面临的一个大问题。农业开发公司正在引进具有高技术的新灌溉系统，以防止这一问题，特别是在地中海区域。灌溉系统由几个要素组成:含水层、水泵、水力网络(管道)和大量的电热器，这些电热器远离中心位置(以公里计)。为了控制整个系统，需要远程操作每个电位值，这需要同时控制信息(开/关电位值)和功率。以最低成本运行的唯一方法是同时使用单线，控制和供电。本文展示了具有集成电力传输的宽灌溉系统的具体通信研究，在非常严格的电流消耗要求下，使用OOK(开关键控)调制和适当的滤波器设计，在传输和接收方面，通过2/spl倍/1.5 mm截面线和不超过10公里的距离进行数据通信。
