A measurement and control system for pressure based on I~2C bus
【摘要】 介绍了I2C总线及其外围器件的特点,设计了以AT89C51单片机为主控制器,以具有I2C总线控制接口的芯片为外围器件的压力测量和监控系统。论述了系统的工作原理、各硬件部分的功能,给出了相应的软件框图。实现了一大型容器中的压力精确控制。
【Abstract】 The characteristics of I2C bus and its peripheral devices are introduced. A measurementand control system for pressure which consists of the AT89C51 single-chip microcomputer as maincontroller, and the chip with interface of I2C bus as peripheral device are designed. The workingprinciple of the system, the function of the hardware are also discussed and the framework of thesoftware design is given. As a result, the precisely control for pressure in a large container is realized.
