　　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.
