摘　　要：为便于自动化设备的生产调试,设计了一款基于I2C总线的测试仪。该测试仪采用模块化设计方法,各个模块均采用AVR单片机作为控制芯片,各个模块间通过I2C总线实现通信,所有模块的工作由一个主控单片机集中控制。该测试仪能模拟自动化设备的实际工作情况,完成设备的可靠性和环境适应性检测,具有便于携带、成本低、稳定性好等优点。A tester based on I2 C bus is designed in order to facilitate production and debugging of automation equipment. Each module adopts AVR single chip microcomputer as control chip,through the I2 C bus communication between various modules,all modules work by a single-chip microcomputer control centralized control. The tester can simulate the actual working status of automation equipment and test the reliability and environmental adaptability of equipment. It has the advantage such as portable,low cost,good stability,etc.
