Control method of pneumatic shield-shaped gate
The invention discloses a control method of a pneumatic shield-shaped gate, which is realized based on a negative feedback closed loop, the negative feedback closed loop is formed by connecting the pneumatic shield-shaped gate with a signal acquisition unit, a PLC (Programmable Logic Controller) and a touch screen, the signal acquisition unit acquires analog signals and switching signals of the pneumatic shield-shaped gate and the surrounding environment thereof in real time, and inputs the analog signals and the switching signals into the PLC; the PLC passively and manually inputs a reference set value through the touch screen, compares the received analog signal with the reference set value, processes the analog signal with the reference set value through a preset logical algorithm, and outputs opening and closing control of the corresponding valve. By applying the control method, the duty ratio of the pulse waveform is automatically switched along with the change of the gate height distance set value through integral and differential transformation processing based on the deviation proportion in the PLC and in combination with PWM adjustment, the gate control precision is improved, the error between gates reaches the millimeter level, and it is ensured that the gates are leveled.
本发明揭示了一种气动盾形闸门的控制方法,基于负反馈闭环实现,该负反馈闭环由气动盾形闸门接设信号采集单元、PLC控制器及触摸屏构成,其中该信号采集单元实时采集气动盾形闸门及其周边环境的模拟信号和开关信号,并输入PLC控制器,该PLC控制器被动通过触摸屏手动输入参考设定值,并将所接收到的模拟信号与参考设定值比较及预设的逻辑算法处理,输出对应阀门的开关控制。应用本发明该控制方法,通过PLC控制器中基于偏差比例的积分、微分变换处理并结合PWM调节,随闸门高度距离设定值的变化而自动切换脉冲波形的占空比,实现闸门控制精度的提升,使得闸门之间的误差达到毫米级,确保闸门得以调平。
