摘　　要：温度与电源电压对高性能的板卡的可靠性非常重要,为了对高速高性能板卡进行有效及时的状态监控,基于数据采集技术提出了一种基于I2 C接口传感器的高速板卡状态监控系统。在该系统中充分利用I2 C接口的优势,设计了8路电压状态监控接口与7路温度状态监控接口,同时给出了硬件电路图和相应的软件设计方法,通过测试证明该系统稳定可靠,目前已经成功的应用于某项目的相应板卡中。The temperature and voltage of power is important to the high performance card＇ reliability. For monitor the real-time parameter of these cards,we have raise a new parameter monitor system of high performance cards based on the I2I C bus interface sensor and FPGA. By the many advantages of I2 C bus interface,we have designed the 8 channels voltage monitor interface and 7 channels temperature monitor interface,while given the hardware circuit and the design way of the corresponding software. Via the test,the monitor system works well,and has been used in the cards of some application items.
