摘要 大规模集成电路的出现极大地促进了微型计算机的快速发展，使我们的生活发生了翻天覆地的变化。正如微型计算机的出现给现代科技的发展注入了新鲜的血液，单片机技术的发展也给工业测控领域带来了新的技术变革。现在，在各个技术领域，单片机都得到了广泛的应用。单片机拥有体积小、重量轻、抗干扰能力强、对环境要求不高、高性价比、开发较为容易，等诸多优点。它已走入千家万户，不论是洗衣机、电冰箱、空调、还是汽车都可以见到它的身影。所以，单片机技术的发展水平已经成为衡量一个国家工业发展水平的重要参考。 陀螺转速测量仪是单片机的简单应用。它利用陀螺角速度传感器来采集物体转速的实时数据，并利用LED数码管作动态扫描从而显示实时转速。该陀螺转速测量仪具有测量精度高，抗干扰性强，适用范围广等多个优点，拥有广阔的市场应用前景。 关键词：微型计算机；单片机；陀螺；转速仪 Abstract LSI appears greatly promoted the rapid development of the microcomputer, so that our life has undergone enormous changes. As the emergence of the microcomputer to the development of modern science and technology has injected fresh blood, but also to the development of SCM technology in the field of industrial measurement and control technology has brought new changes. Now, in various technical fields, microcontrollers have been widely used. SCM has small size, light weight, anti-interference ability, less demanding on the environment, high cost, relatively easy to develop, and many other advantages. It has entered every household, whether washing machines, refrigerators, air conditioners, or car can see its shadow. Therefore, the level of development of SCM technology has become the measure of a countrys level of industrial development an important reference. Gyro Speed Gauge is simple microcontroller applications. It uses gyro angular velocity sensor to collect real-time data of the object speed, and make use of digital LED to display real-time dynamic scanning speed. The gyro speed measurement instrument has a number of advantages of high precision, strong anti-interference, wide application, has a broad market .
