毕业论文-基于单片机的园林智能灌溉系统.docx

基于单片机的园林智能灌溉系统摘要水是地球上所有生命的必备资源，但是随着淡水资源的污染和浪费，可用的部分已经越来越少。在我国，农业和园林灌溉用水存在的巨大的浪费现象，如果能对灌溉进行智能化管理，将极大的提高淡水资源的利用率，从而节约水资源。本设计是一款基于STC89C52RC单片机的园林智能灌溉系统，能够做到对浇灌植物根部土壤湿度的实时检测，并在单片机内对检测到的湿度信息进行处理，并根据以上的处理结果控制水泵浇水，从而进行智能浇灌。本系统包含按键模块，湿度传感器，AD数模转换模块，STC89C52RC单片机，显示模块，报警器电路，继电器驱动模块等部分。本系统在工作时，可以先通过按键对土壤湿度的标准值进行设置，设置完成后，土壤湿度传感器对土壤的湿度进行实时监控，当湿度数据通过模数转换器的转换，并传送给单片机后，单片机就会对检测到的湿度信息和预设的标准值进行比较处理。当湿度低于设定的标准值时，单片机就发出指令，控制驱动模块进行自动浇灌。关键词：灌溉，单片机，传感器，A/D转换，LED 显示Garden intelligent irrigation system based on single chip microcomputerElectronic Information of Science and Technology 11-2 Jia XiaojieSupervisor Chen JingAbstractWater is essential for all life on earth, but with the pollution and waste of fresh water resources, the available parts have become less and less. In China, agricultural and landscape irrigation water has a enormous waste phenomenon, if we can manage the irrigation intelligently,we will greatly improve the utilization of freshwater resources rate, thereby saving water resources. This design is a intelligent irrigation system based on STC89C52RC MCU, which is to achieve the real-time detection for the plant root soil moisture, and humidity information processing in the single chip computer, according to the results of process control watering pump, thus the intelligent irrigation. This system contains the key module, humidity sensor, AD digital analog conversion module, STC89C52RC microcontroller, display module, alarm circuit, relay driver module and other parts. The system at work can first through the standard button on the soil moisture values to be set, after setup is complete, the soil humidity of the soil moisture sensor for real-time monitoring, when humidity data through the conversion of analog to digital converter and sent to the microcontroller, SCM will the detected humidity information and a preset standard value for comparing and processing. When the humidity is lower than the set of standard value, the microcontroller sends out the instruction, the c
