　　Air operated moves the carrier vehicle and the PLC control
 Air operated namely uses the air pump and the air valve control air current, the positive governing barometric pressure and the current capacity, enable the air to have the vibration.
 The programmable controller (PLC) is taken the microprocessor as the core, collection computer technology, the automated control technology in a body one new industry control system. PLC has used the model computer structure, mainly includes CPU, RAM, ROM and the input/ Output connection electric circuit and so on. If regards as PLC a system, this system is composed by the input variable -PLC- output variable, the exterior each kind of switching signal, the simulated signal, the sensor examine the signal took PLC the input variable, they input after the PLC exterior post to the internal register in, after the PLC interior logic operation or other each kind of operation, processing delivers the output terminal, they are the PLC output variable, carries on each kind of control by these output variables to the auxiliary equipment.

 气动即采用气泵和气阀控制气流，直接控制气压和流量，使得空气发生振动。
 可编程控制器（PLC）是以微处理器为核心，集计算机技术、自动化控制技术于一体的一种新型工业控制系统。PLC采用了典型的计算机结构，主要包括CPU、RAM、ROM和输入/输出接口电路等。如果把PLC看作一个系统，该系统由输入变量-PLC-输出变量组成，外部的各种开关信号、模拟信号、传感器检测的信号均作为PLC的输入变量，它们经PLC外部端子输入到内部寄存器中，经PLC内部逻辑运算或其它各种运算、处理后送到输出端子，它们是PLC的输出变量，由这些输出变量对外围设备进行各种控制。
 PLC控制系统一般采取易于理解和掌握的梯形图语言及面向工业控制的简单指令,形象直观，是基于现场总线技术、完全开放，采用先进的软硬件技术。PLC 控制具有结构简单灵活、抗干扰能力强、安全可靠、安装便利、故障率低、维护简单、大幅度节约使用成本的特点，能满足各种中小规模过程控制、顺序逻辑控制和数据采集任务需求，已逐渐广泛用于工业控制系统中，包括冶金、矿业、机械、轻工等领域，为工业自动化提供了有力的工具。
