摘　　要：基于I2C总线接口的智能温控系统由AT89C2051单片机和LM76温度传感器及软件组成。通过单片机AT89C2051通用I/O口模拟I2C总线,控制温度传感器LM76。并采用监控程序、I2C总线模拟通用子程序等软件实现测控功能和数字平滑滤波。该系统留有RS-485通信端口,符合先进电源接口(ACPI)规范。The intelligent temperature controlling system based on I^2C Bus interface is composed of singlechip AT89C2051, temperature sensor LM76 and software,I^2C bus was simulated by AT89C2051 through I/O interface, and temperature sensor LM76 was controlled by AT89C2051. And universal subprogram was simulated by monitor routine and I^2C bus to realize control function and digital smooth filtering. The system has RS-485 communication interface, and is up to the standard of ACPI.
