随着生活质量的提高，越来越多的人喜欢在家中养花，但经常因不能及时照顾花的生长环境而导致花枯萎。为改善这种情况本系统提出了一种基于51单片机的智能浇花系统，该系统是以51单片机为主控制器，通过DS1302时钟模块设定在固定的时间进行浇水，浇水的时间为60秒；同时使用温度传感器DS18B20和湿度传感器对土壤的温度和湿度进行检测，当检测到的环境状况是属于土壤缺水的情况，则主控制器会打开水泵开关开始浇水，当不在是缺水的情况时则停止浇水。经过后期的多次测试，该系统可以成功的实现预期的设计目标。(With the improvement of the quality of life, more and more people like to grow flowers at home, but often fail to take care of the growing environment of flowers in time to cause the flowers to wilt. In order to improve this system, an intelligent watering system based on 51 single-chip microcomputer is proposed. The system is based on 51 single-chip microcomputer as the main controller. The system is set at a fixed time through the DS1302 clock module to water for 60 seconds. The temperature and humidity of the soil is also used by the temperature sensor DS18B20 and the humidity sensor. The main controller opens the water pump switch to water and stops watering when the water is not in the condition of water shortage. After many tests, the system can achieve the desired design goals successfully.)

在下的毕业设计， 本题要求设计一个直流电机控制系统。在设计中，采用国产单片机中目前比较新式的STC12C5A60S2作为整个控制系统的控制电路的核心，因为STC12C5A60S2内部有PCA模块，可以产生PWM波形；采用带中断的独立式键盘作为命令的输入，每当按键时蜂鸣器响；配以LCD12864显示实现对带光码盘的直流电动机转速参数的测量、显示和控制。LMD18200驱动模块内部是H型驱动电路，驱动能力较强，完成电机正反转以及速度的控制。为优化直流电机的响应，采用PID反馈，实现闭环控制。(Graduation in the next, and that the requirements to design a DC motor control system. In the design, the use of the relatively new domestic microcontroller as a control circuit of STC12C5A60S2 entire control system core, because STC12C5A60S2 internal PCA module can generate PWM waveforms using a separate keyboard with interrupt input as a command, whenever the button When the buzzer sounds accompanied LCD12864 display realize the measurement of the optical encoder with DC motor speed parameters, display and control. LMD18200 internal drive module is H-drive circuit, driving ability, and the speed of completion of the motor reversing control. In order to optimize the response of DC motor, using PID feedback, closed loop control.)
