摘　　要：本文围绕SDI测试问题作了系统地分析研究,设计了一套全自动测试方案,摒弃了以往传统测试中的人工操作、准确度差等缺憾,采用ATMEL公司生产的MCS-51系列单片机89C52、电磁流量变送器等智能元件,设计了单片机控制系统、电源系统、看门狗控制等硬件电路,建立了LCD液晶显示模块,开发了大量的相应程序,实现对SDI指数的自动测试。经过反复论证、调试,成功地研制出智能型SDI测试系统。该系统具有操作便捷、测量精度高、测试速度快以及显示界面友好等特点,填补了国内该类测试仪器的空白。According to the problem of the test method of the SDI, we design a new method instead of the one before. It can get the data automatically, decrease the measuring error and increase the accuracy. The main parts of SDI device conclude the MCS-51 of ATMEL company and flux meter. We design single chip system, power system, watchdog system ,display system of LCD,and software, etc. After a series of trial, we develop the device finally. The device is accurate and has a friendly interface. The intelligent device meets the need of the market. It operates easily and has the virtue of accuracv. It is the first time that we develop it in the domestic market.
