摘　　要：温度是影响太阳能电池组件层压质量的重要工艺参数,为了实现层压过程温度的精确控制,设计了基于LabVIEW的层压机模糊PID温度测控系统,详细描述了系统硬件、软件的设计过程,系统采用上下位机模式,下位机选用S7-200系列中的CPU226型PLC作为主控制器,上位机采用图形化编程软件LabVIEW作为软件开发平台,另外在平台下设计了模糊PID控制器,并进行了仿真。结果表明:系统温度超调量明显减小,控温效果明显增强,满足了预期要求,保证了产品质量。Temperature is a very important process parameter affecting lamination quality of the solar cell module. In order to realize accurate temperature control of the laminator, the fuzzy PID temperature control system of laminator based on LabVIEW was designed, and the implementation process of the hardware and software was described in detail. The system adopted upper computer and lower computer mode, the CPU226 PLC of S7 - 200 series was used as the main controller in the lower computer, and the graphical programming software LabVIEW was used as software development platform in the upper computer. In addition, Fuzzy - PID controller based on LabV1EW was designed. The results show that the system can deerease the overshoot of temperature, and obviously enhance control effect of temperature,which has reached the anticipated demand and ensure products quality.
