| 针对目前沥青粉碎生产线采用的继电器控制系统监控能力低、稳定性差和人工操作复杂等缺点，课题组提出了一种基于PLC的沥青粉碎生产线控制系统。系统采用电流互感器和温度传感器采集了粉碎机电机温度和电流信息，实现了电机过热保护和过载保护。根据PLC的工作特点，设计了整套控制线路和PLC程序，实现一键启动和关闭整条生产线；设计了基于触摸屏的友好的人机操作界面，实现了设备状态监控、内部参数设定和历史数据查询等功能。应用结果表明：该系统自动化程度高，使用方便，提高了粉碎生产线的生产效率。该控制系统能有效降低粉碎系统的操作难度，提高粉碎系统的稳定性。 |

| Aiming at the disadvantages of the current relay control system used in asphalt crushing production line, such as low monitoring ability, poor stability and complicated manual operation, a PLC based asphalt crushing production line control system was proposed. The current transformers and temperature sensors were used to collect the temperature and current value of the motor to achieve motor overheat protection and overload protection. According to the working characteristics of PLC, the whole set of control circuit and PLC program were designed to realize the start and shutdown of the whole production line with one button. A friendly HMI based on touch screen was designed which realizes the functions of device status monitoring, internal parameter setting and historical data query. The application results show that the system has a high level of automation and the convenience of use, which improves the production efficiency of the crushing production line. The control system can effectively reduce the operation difficulty of the crushing system and can improve the stability of the crushing system. |
