| 为解决EJⅡ-100型杠杆式力标准机操作复杂、自动化程度低、电子元器件故障、维修频繁等问题，在对力标准机机械结构的检查修复的同时对电器电路及控制系统进行整体升级改造，利用当前主流的PLC控制模式代替传统的单片机控制，并对改造后力标准机功能及技术指标进行测试，使力标准机的工作稳定性及自动化控制程度得到提升，经实验证明，改造后的力标准机各项功能及技术指标均符合设计目标及国家检定规程要求。 |
| 英文摘要: |
| In order to solve the problems of complicated operation, low automation, failure of electronic components and frequent maintenance of EJ II-100 Lever Force Standard Machine, the electrical circuit and control system were upgraded while the mechanical structure of EJ II-100 Lever Force Standard Machine was inspected and repaired. The current mainstream PLC control mode was used to replace the traditional MCU control, and the function and technology of the transformed Force Standard Machine were also improved. The test results show that the working stability and automation control degree of the force standard machine are improved. The experiment proves that the functions and technical indexes of the improved force standard machine meet the design objectives and the requirements of the national verification regulations. |
