淋浴水温调节器设计 摘 要 目前淋浴热水器在家庭中运用越来越广泛，然而市面上存在的淋浴调节方式主要是通过手动调节开关量的大小来控制水温的高低。这种调节方式不能够很好的控制水温的高低，有时由于调节开关距淋浴地点较远，给人们调节水温带来不便，因此，这种调节方式不能够满足人们追求生活舒适的要求。 本论文介绍了一种以单片机为主要控制器件，以DS18B20为温度传感器的新型淋浴水温调节器。主要包括硬件电路的设计和软件设计。硬件电路主要包括主控制器，测温控制电路和显示电路等，主控制器采用单片机STC89C54RD+，温度传感器采用DS18B20，显示电路采用8位共阴极LED数码管动态扫描显示。测温控制电路由温度传感器和预温度电路组成，当实际测量温度值大于或小于预置温度值时，发出信号，从而发出指令控制冷水口和热水口的阀门，使热水和冷水进入到一定大小的容器，保证容器的水温在一定范围内变化。软件设计主要包括主程序，测温子程序和显示子程序等。该设计能够实现精确控制水的温度，其中由于单片机的集成化，使产品小型化、智能化，既提高了产品的功能和质量，又降低了成本，简化了设计。 关 键 词：STC89C54RD+，DS18B20，显示电路，测温控制电路  Shower water temperature regulator design ABSTRACT Shower water heater is currently more widely used at family, however, there is a mainly way to regulate shower which through manual adjustment switch to control the temperature in the market . This adjustment is not a good way to control the temperature , and sometimes regulating switch is far away from the shower location, which is not convenience to control the temperature. therefore, this adjustment method is not able to satisfy the people to pursue life comfortable request. This paper introduces a kind of new shower water temperature regulator, which use the Single chip as the main control device and DS18B20 as the temperature sensor. It mainly includes hardware circuit design and software design. Hardware circuit mainly includes the main controller, temperature control circuit and display circuit , the main controller uses the Single chip STC89C54RD +, temperature sensor adopts DS18B20,display circuit uses eight total cathode tube dynamic scanning LED digital display. Temperature control circuit is consist of temperature sensor and the preset temperature comparison circuit, and when the actual measured temperature greater than or less than the preset temperature value, a signal to send commands to control the mouth of cold water and hot water valve port, so that hot and cold water into the container to a certain size, to ensure that the temperature of the container changes a certain range.
