基于CAN总线的智能喷灌远程控制系统

Remote control of smart sprinkler system based on CAN-BUS

目前,城市草坪仍采用人工或定时的喷灌方式,尚未采用合理的喷灌策略,且缺乏集中管理的能力;不合理的喷灌不仅会导致草坪生长不良,更是对有限水资源的浪费。提出一种实现草坪智能化远程灌溉的新思路。根据草坪需水量、耐热性及病害规律制定了喷灌策略,利用嵌入式控制器实现智能处理。结合城市草坪的特点,利用太阳能锂电池为系统供电,实现了系统能源自给。系统采用CAN总线控制终端与各节点的通讯,实现用户的远程监控及网络化管理。研究结果表明:智能喷灌远程控制系统具有效果良好、价格低廉、可靠性高、易于维护等优点。

Till now,most lawn is still irrigated manually or timely.That means lack of proper irrigation strategy and information management ability.However,irrational irrigation method will not only lead to unhealthy growth of lawn,but also waste of water.A new idea for lawn intelligent remote irrigation was put forward.The smart sprinkler strategy was created by researching the characters of lawn,such as water demand,heat resistance and diseases law.And the embeded control system can apply the strategy to irrigate intelligently.Tying the urban lawn features,the system was designed to be driven by solar,which makes it an energy self-sufficiency system.What’s more,the sprinkler system gains the CAN bus-based network management function,which simplify the user’s contol and management.Finally,the experimental results show that the system has the advantages of good effect,low cost,high reliability,easy maintenance,etc.And it will meet the demand of energy saving and environmental protection.
