该技术的工作原理:在需要开启并下风[门的时,PLC把控制信号传送给二位五通双控电磁阀,此时电磁阀运动到相应位置实现供气,汽缸的活塞将会带动行走部分实现向外运动,而随即打开风门。上所设置的用于减小开启压力的窗口。若将开启角度设置成25″,当小窗开启到同风[门的夹角成25°时,小窗就会被固定销挡住而无法继续打开,但是行走支点却会继续向前移动来带动风门开启。当风[]的开启角度达到直角时,操作动作就会自动停止,车辆与行人即可通行。当风门需要关闭时,PLC将会把相反的控制信号传送给二位五通双控电磁阀,使其换向来控制压气进入汽缸的另–端,此时汽缸的活塞就会带动行走部分移动返回,在关严小窗后,然后在带动风门运动,直到风门被完全关严。
机电设备采用PLC进行控制的优点是显而易见的,其可避免许多无意义的工作,提高机电设备维修的效率,运行安全可靠,能够较好的效果。同时,由于采用目前控制领域先进通用的PLC控制器进行控制,系统的软硬件部分可形成模块化结构,比较便于扩展。
The working principle of the technology: when the door needs to be opened and downwind, PLC sends the control signal to the two-position five-way double-control solenoid valve, then the solenoid valve moves to the corresponding position to achieve air supply, the piston of the cylinder will drive the walking part to move outward, and then open the throttle. If the opening Angle is set as 25″, when the small window is opened to the Angle of 25° with the wind [door], the small window will be blocked by the fixed pin and cannot be opened, but the walking fulcrum will continue to move forward to drive the damper to open. When the opening Angle of the wind [] reaches a right Angle, the operation will stop automatically, and vehicles and pedestrians can pass through. When the damper needs to be closed, PLC will send the opposite control signal to the two five-way double control solenoid valve, so that it will change the control air into the other end of the cylinder, at this time the cylinder piston will drive the walking part of the movement back, after closing the small window, and then drive the damper movement, until the damper is completely closed.
Mechanical and electrical equipment using PLC control advantages are obvious, it can avoid a lot of meaningless work, improve the efficiency of mechanical and electrical equipment maintenance, safe and reliable operation, can be better effect. At the same time, due to the use of the current control field advanced general PLC controller for control, the software and hardware parts of the system can form a modular structure, easy to expand.
