摘要
为了适应农田灌溉信息化和自动化的要求,本着经济性、实用性与可靠性的原则,基于POCSAG编码传输技术,设计了农田灌溉控制系统;论述了从发射到接收过程中POCSAG编码在容量、抗干扰和传输距离等方面的优势,以及由此构成的信号传输系统。该系统具有技术成熟、设备成本低、易实现等特点,解决了农田灌溉中点多、面广、地形复杂和距离远等问题,并自成一个独立控制系统,为建设农田灌溉控制信息化和提高用水管理水平提供了广阔应用空间。
Around economy, practicability, reliability, the field irrigation system is designed based on POCSAG coding technology for adapting the requirement of the information and automation of field irrigation. From launding to receiving, the superior of POCSAG coding is discussed about the capacity, resistancing disturbance, transmission distance, The system composed of POCSAG coding has provided with characteristic of technology of mature, low cost, easy realization and so on. The matter for many places, broad area, complx soil shape and so on has had solved. The independent control system formed has supplied broad using space for the information of field irrigation and the level of raising management.
