给出了一种基于Proteus7.5仿真实现的液晶温度显示器设计.系统硬件电路采用AT89C52单片机、DS18B20数字温度传感器和LM016L液晶显示器等主要元件.采用Keil uVision3设计系统软件的C51源程序并调试.在Proteus 7.5平台上,对系统进行了软硬件仿真.仿真结果表明,该系统的浏量和显示精度达到了0.1℃.通过Proteus对液晶温度显示器的工作状态进行模拟,以检验和评估设计的可行性,缩短了实际系统开发周期,降低了开发成本,是一种有效可行的仿真方法.%It constructs a Proteus7.5-based liquid temperature display simulation system .The system adopts AT89C52 MCU,DS18B20 digital temperature sensor and LCD LM016L as main components. The design and debug of system's soft was built on Keil uVision3. The simulation of system hardware and software were built on the platform of Proteus ISIS7.5. The result reveals that the system's precision is 0.1℃. The liquid temperature display's working state was simulated by Proteus to verify and evaluate the design's feasibility,which reduces the actual development cycle and the development cost. The Proteus-based simulation design is an effective and feasible simulation method.
