The invention discloses a driver operation auxiliary device for a container bridge. According to the device, a Yaskawa main PLC is connected with a trolley absolute value encoder, a lifting absolute value encoder and a Yaskawa communication module, and the Yaskawa communication module is connected with a touch screen; and the lifting safety height and the trolley safety position are confirmed through unlocking and locking pulse signals and stored in an intermediate register, then the lifting height and the trolley position are stored in real time in the same way and serve as the safety value of next equipment operation, when the lifting height or the trolley position is lower than the safety value, a voice alarm is given and the situation is displayed on an touch screen interface, and if the equipment still runs at a high speed, forced speed reduction or emergency stop are carried out on a trolley mechanism through a main program. According to the device, the accidents of box collision and ship collision in the operation process of a loading and unloading bridge can be effectively avoided.
本发明公开了一种集装箱装卸桥司机操作辅助装置。本发明安川主PLC分别连接小车绝对值编码器、起升绝对值编码器和安川通讯模块,安川通讯模块连接触摸屏;使用开闭锁脉冲信号确认起升安全高度和小车安全位置,并存储在中间寄存器中,然后依次类推,实时存储起升高度和小车位置,并作为下次设备运行的安全值,当起升高度或小车位置低于安全数值时,语音报警并通过触摸屏界面显示,若设备仍在高速运行时,通过主程序对小车机构进行强制降速或紧急停止。通过本发明可以有效地避免装卸桥在作业过程中碰箱和撞船事故的发生。
