辽宁桥式起重机的控制
Bridge crane control
一、辽宁桥式起重机控制形式
Crane control form
1、凸轮控制器控制
1, cam controller
2、主令控制器控制
2, the main control of the controller
二、自动控制
Two, automatic control
1、可编程序控制器自动控制。起重机各机构的运行要依靠程序控制装置来实现，现在起重机多使用可程序控制器来控制。
1, programmable controller automatic control. Crane operation of the various agencies to rely on the program control device to achieve, and now more than the use of a crane to control the programmable controller.
2、自动定位装置控制。起重机的自动定位，一般是根据被控对象的使用环境、精度要求来确定装置的机构形式，自动定位装置通常使用各种检测元件与继电器、接触器或可编程序控制器相互配合，以达到自动定位的目的。
2, automatic positioning device control. Automatic positioning of the crane, the general is to determine the form mechanism according to the requirements of the controlled object environment, precision automatic positioning device usually use various detection devices and relays, contactors or PLC with each other, in order to achieve the purpose of automatic positioning.
3、地面操做、有线与无线遥控葫芦式起重机采用地面控制，其关键部件是手动按钮开关。有线遥控是通过专用电缆或动力线作为载波体，对信号用调制解调器传输方式，达到只用少量通道即可实现控制的方法。
3, ground operation, wired and wireless remote control hoist crane using ground control, the key part of the manual button switch. Wired remote control is a dedicated cable or power line as a carrier, the signal with modem transmission mode, to achieve a small number of channels can be used to control the method.
无线遥控利用当代电子技术，将信息以电波或光波为通道形式传输，达到控制的目的。
Wireless remote control by the use of modern electronic technology, information will be transmitted in the form of radio waves or light waves, to achieve the purpose of control.
4、大车运行机构的纠偏和电气同步。纠偏分为人为纠偏和自动纠偏，人为纠偏是当纠偏超过一定值后，纠偏信号发生器发出信号，司机断开超前支腿侧的电动机，接通滞后支腿偏的电动机进行调整。自动纠偏是当偏斜超过一定值时，纠偏指令发生器发出指令，系统进行自动纠偏。电气同步是在交流传动中，常用带有均衡电动机的电轴系统来实现电气同步。
4, the cart running mechanism of the rectification and electrical synchronization. Deviation correction and automatic correction for artificial, man-made rectification is when the deviation exceeds a certain value, correcting signal generator signal, motor driver off ahead of the leg side, connecting leg partial motor lag adjustment. Automatic deviation correction is when the deviation exceeds a certain value, the error correction instruction generator sends out the instruction, the system carries on the automatic correction. Electrical synchronization is used in AC drive, often with a balanced motor shaft system to achieve electrical synchronization.
5、辽宁桥式起重机电磁铁及其控制电路。主要是提供电磁铁的直流电源及完成（吸、放料）控制要求。其工作方式分为定电压和可调电压两种控制形式。
5, crane electromagnet and its control circuit. The main purpose is to provide DC power supply and complete (suction, discharge) control requirements. It can be divided into two control modes: constant voltage and adjustable voltage.
