摘要
新开发的GM－A、GM－B气体比例混合器，使用单片微处理器，实现了按任意设定的二或三种气体的体积百分比，控制各气体充气电磁阀，达到了获取预定比例的混合气体的目的。该装置具有系统稳定性好、精度高、易于满足不同的供气量等优点，目前已应用于气调包装实际生产过程中。文章介绍了该装置中系统程序的控制原理、硬件结构和配气精度测试结果。
Applying the single chip microprocessor in the process of controlling gasproportion mixing has several advantages such as good systematic stability, high precision,flexibility to supply different amount of gas, and being used in the practical productionprocess of modified atmosphere packaging. This introduced control1ing principle, hardwarestructure and precision of the equipment that is newly developed GM - A, GM - B gasproportion mixer's system with the single chip microprocessor, which realizes the anystipulated two or three gases' volume percentage, controlling all gases' magnetic valves,fulfilling the purpose of obtaining prestipulated proportional mixed gas.
