基于CAN总线的棉花膜下滴灌控制系统设计

棉花膜下滴灌技术在新疆生产建设兵团得到了广泛应用.计算机自动化控制技术在灌溉中的应用是实施现代农业生产管理的重要环节,也是实现精准农业的前提条件.现有的自动化灌溉控制系统存在成本高、系统复杂、可靠性低等缺点.为此,提出了基于现场CAN总线的膜下滴灌控制系统.该系统包括上位机与下位机两个子系统,每个子系统设计又包括硬件与软件两方面.实践证明,该系统具有可靠性高、实时性强、成本低等优点,非常适合棉花滴灌控制的需要.

Design of Automatic Control System of Mulch Trickle Irrigation for Cotton Based on the CAN Bus

the technology of mulch trickle irrigation for cotton get to use widely in Xinjiang Bingtuan, the application of computer automatic control technology for irrigation is a important tache of actualizing agriculture production manage and a precondition condition of realizing exactitude agriculture. The existing automatic irrigation control system has many shortcomings, for example, high cost, complex system, low reliability, and so on. So we bring forward the automatic control system of mulch trickle irrigation for cotton based CAN bus. The system includes the host computer and the assistant computer, each subsystem's design includes hardware and software. The article not only introduce the system design point but also bring forward the system noticed proceeding. The practice shows that it has many merits, for example, high credibility, and good real-time ability and low cost, and so on. It fits the requirement of automatic control of mulch trickle Irrigation for cotton.
