【摘要】 介绍了变速箱机械封闭式疲劳寿命试验台的结构和控制方法。为适应寿命试验台试验周期长、强度大、不断更换试件项目的特点,电气系统采用"工控机-PLC-仪表"和"PLC-仪表"可变结构模式。"PLC-仪表"结构作为基本配置,采用端子连接,用于底层设备控制和数据采集;工控机进行过程管理和数据处理,工控机与其它控制设备采用串行通信联系。更多还原

【Abstract】 Introduces the structure and control method of gearbox tests. In order to meet the test’s features of long cycle,labour-intensive and samples replacing frequently,the platform’s control system adopts "IPC-PLC-Meter" and "PLC-Meter" variable structure model."PLC-Meter" as the basic configuration with terminal connection is used for bottom device control and data acquisition. IPC for process management and data processing connects with other devices through seriel conmmunication.更多还原
