摘　　要：介绍开发的一种适于内燃机工作循环研究的高速数据采集系统,其采样速率、数据精度及处理分析功能与专业品牌的高速数据采集仪相当,但成本价格远低于后者,且使用方便。实际试验应用结果表明,所开发的高速采集系统运行稳定,数据可靠,界面友好,完全满足项目测试要求,达到了设计开发的预期目标。A high-speed data acquisition system which can be used in the research of internal-combustion engine working cycle has been developed. Its sampling rate, data accuracy and ability in processing and analysis are as good as famous ones, but much cheaper and easy to use. The test result shows that this system runs steadily with reliable data and friendly interface, thus satisfy the test requirement perfectly and reach the expected target in developing.
