混凝土搅拌控制系统采用西门子S7-200系列的PLC作为核心元件,采用SWD-100型称重显示控制器对每个原料仓内原料进行称重,当满足设定值时即全部投入搅拌机进行搅拌,若系统发生故障时,会启动报警系统,以便提醒现场工作人员进行检查和修复。本设计实现了混凝土搅拌过程的全自动控制,运行安全可靠。通过与计算机通讯实现人机界面操作,能够很好的完成了故障的诊断和处理、混凝土搅拌的配比、混凝土产量的统计等工作。
Concrete mixing control system uses Siemens S7-200 series PLC as the core components, the use of SWD-100-type weighing display controller for each raw material warehouse weighing, when the set value is satisfied that all the inputs into the mixer for mixing, If the system fails, it will start the alarm system to remind the site staff to check and repair. The design of the concrete mixing process to achieve full automatic control, safe and reliable operation. Through the communication with the computer to realize the man-machine interface operation, the fault diagnosing and processing, the ratio of concrete mixing and the statistics of concrete yield can be accomplished well.
