【摘要】：自动售水机是一种从饮用水“终端”解决水质问题的设备，它采用科学的、先进的净化技术对饮用水进行深度净化处理，提高了饮用水的质量。研究自动制水售水系统对人类解决水资源污染、提高饮用水质量具有极其重要的意义。本课题研究了自动制水售水工作原理，在此基础上确定了制水售水系统的总体设计方案。对前端制水流程和制水技术、后端售水流程和售水技术进行了详细的分析介绍，并确定了制水智能化方案和售水自动化的方案。制水的核心技术是采用了RO反渗透技术（又称逆渗透），它可以滤除净水中的细菌、病毒等有害物质和其它一些可溶物，单片机控制进水电磁阀的打开与关闭实现自动制水储水过程。后端售水部分使用非接触IC刷卡售水和投币售水两种售水方式。单片机通过监测储水箱的水位变化控制电磁阀、水泵的打开与关闭和实现自动制水和售水过程。为了保证储水箱进水压力和出水压力，采用水泵进行抽水制水，保证制水和灌装的顺利进行。本文按照售水系统的整体设计方案，完成了制水售水系统的硬件电路设计。分析了电源电路、射频卡读写电路、电磁阀驱动电路、泵驱动电路、显示电路的设计。文章的最后完成了制水售水系统的软件设计部分，通过软件部分的设计，单片机检测到输入信号后输出控制信号控制外围器件动作，实现了完整的自动制水和售水功能。
[Abstract]:Water vending machine is a kind of equipment for drinking water from the "terminal" to solve the problem of water quality, the use of scientific and advanced purification technology for deep purification treatment of drinking water, improve the quality of drinking water. The water system of automatic water to solve water pollution on human resources, has very important significance to improve the drinking water quality.
The research of the automatic system of water water working principle, on the basis of the overall design scheme of water water system were determined. The end of water flow and water technology, water flow and water back-end technology are analyzed in detail, and to determine the water and water automation intelligent solutions the scheme is the key technology of water making RO reverse osmosis technology (also known as reverse osmosis), it can be used in water purification of bacteria, viruses and other harmful substances and other soluble substances, MCU control water valve to open and close the automatic water storage process. Some use of non contact water back IC card selling water and water of two water coin. SCM control solenoid valve through the change of water level monitoring of water tank, water pump and the opening and closing of the automatic water making and selling process. In order to ensure the water storage tank and a water inlet pressure The pump is used for pumping water to ensure the smooth progress of water making and filling.
According to the overall design of the water system, completed the hardware circuit design of water water system. Analysis of the power supply circuit, RF card reader circuit, driving circuit of the electromagnetic valve, pump drive circuit, display circuit design. Finally completed the software design of the system of water water system, through the design the software part of the MCU to detect the input signal output control signal to control the peripheral device action, to achieve a complete automatic water making and selling water.
