給出了一種基于Proteus7.5仿真實現的液晶溫度顯示器設計。系統硬件電路采用AT89C52單片機、DS18B20數字溫度傳感器和LM016L液晶顯示器等主要元件。采用Keil uVision3設計系統軟件的C51源程序并調試。在Proteus 7.5平臺上，對系統進行了軟硬件仿真。仿真結果表明，該系統的測量和顯示精度達到了0.1 °C。通過Proteus 對液晶溫度顯示器的工作狀態進行模擬，以檢驗和評估設計的可行性，縮短了實際系統開發周期，降低了開發成本，是一種有效可行的仿真方法。

　　Abstract:

　　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°C. 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.
