欧姆龙PLC在QCS008液压实验台控制中的应用
摘要
由于传统的液压实验台采用继电器等元件作为控制系统的控制元件，存在可靠性、灵活性差,自动化低的缺点。同时，液压元件和管路在实验台上的位置不能随意改变，操作只能是人工手动，安全性较差。所以本次设计利用三菱PLC对QCS003B液压实验台进行改进。这样不但扩大了液压实验台的力能范围，还提高了控制系统的柔性。
在该控制系统中，操作人员通过PLC发出指令，驱动时间继电器。时间继电器的定时信号是控制系统的输入信号，控制系统的输出信号是实验台的各电磁阀的电磁信号，从而控制液压系统的的液压油的流向，达到控制系统控制的目的。因此，通过PLC控制改进后的液压实验台作为教学的液压实验台系统更能充分发挥学生的主观能动性，满足开拓创新的实验需要。

OMRON PLC in QCS008 hydraulic test stand control of the traditional summary of a test using hydraulic relay All components such as the control system of control components, there is reliability, flexibility poor, low-automation shortcomings. Meanwhile, hydraulic components and pipes in the experimental stage can randomly change the location, operation only by manual, security is poor. Therefore, the use of this design Mitsubishi PLC Style hydraulic test stand improvement. This has not only expanded the hydraulic test stand to the edge, but also the improved control system flexible. In the control system, operating through the PLC issued a directive, the drive time relay. Time Relay is the timing signal control system of the input signal, control system output signal is a test of the electromagnetic valve electromagnetic signals thus control the hydraulic system of hydraulic oil flow control system to achieve the objective. Therefore, PLC control through improved hydraulic test-bed t
