单片机控制的定时浇水电路的设计 摘 要 通过研究盆景花卉正常生长的各种参数，根据是否需要水和光照而自动浇灌，很好地控制花卉生长的温度及湿度。考虑干扰的消除措施，有效地避免干扰的产生，采用太阳能给电池充电使之环保又节省了资本，系统的器件需要采用高性能低价原件，降低开发成本低，而且能够满足大多数用户的需求。 本系统将对温室环境中土壤湿度、光照强度、温度因子的调控进行自动化控制以期达到最佳的控制效果。系统硬件设计，完成硬件原理图。硬件将通过调研对比分析，选用高性价比元件，采用一些成熟电路设计，达到提高系统的稳定性、可靠性与精度，降低成本，提高市场竞争力的目标。程序设计流程与程序清单。软件设计将采用C语言设计，提高系统的修改、调试与升级的能力。通过系统仿真，检验系统硬件与软件设计的合理性，达到预期的功能。 关键词 单片机/浇水电路/温度/湿度/传感器  SCM water circuit timing circuit design ABSTRACT Potted flowers by studying various parameters of normal growth, according to the need for water and light and automatic watering, good control of temperature and humidity of the growth of flowers. Consider the interference cancellation measures to effectively prevent the generation of interference, the use of solar energy to charge the battery to make it environmentally friendly and save the capital, the system uses high-performance low-cost devices that require the original, lower development costs low and meet the needs of most users . The system will be in the greenhouse soil moisture, light intensity, temperature control for automatic control factors to achieve the best control results.System hardware design, complete hardware schematics. Comparative analysis of hardware through research, the choice of cost-effective components, using a number of mature circuit design, to improve system stability, reliability and accuracy, reduce costs, increase market competitiveness objectives. List of programming processes and procedures. Software design will use C language design and improve system modifications, commissioning and upgrading of skills. Through the system simulation, test system hardware and software design is reasonable, to achieve the desired function.
