摘要
为了提高林果采收效率,根据偏心式林果振动采收机的工作原理以及控制要求,设计了基于PLC和组态软件的采收机控制系统。该系统采用两级控制方案,上位机由触摸屏和MCGS组态监控软件组成,实现采收过程监控,包括采收参数设定、显示、采收方案选择以及报警等;下位机采用西门子S7-200系列可编程逻辑控制器(PLC),通过梯形图编程,实现采收机开关控制以及采收参数采集等,上位机与下位机通过RS232/485串口通讯。该系统满足设计要求,界面友好、运行可靠、操作方便,提高了林果采收自动化水平和采收效率。
In order to improve the efficiency of forest-fruit harvesting, according to the working principle and control re- quirements of the eccentric-type forest-fruit vibration harvesting machine, a control system was developed based on PLC and configuration software. A Two-grade control method was used in the system, the host computer was developed by the touch screen and configuration software of MCGS to achieve harvesting process monitoring , including the harvesting pa- rameters setting and displaying, harvesting program selecting and fault alarming, etc. The lower computer was developed with SIMATIC S7-200 PLC to control the harvesting machine and collect the harvesting parameters, such as vibration frequency and harvesting time, etc. The lower computer was communicated with the host computer through RS232/485 serial port. The system was user-friendly, reliable running and easy operating, which increased automation level and har- vest efficiency.
