摘要
为更加直观地监测轮胎橡胶硫化等生产过程中的工艺参数,弥补现有圆图无纸记录仪的功能缺陷,设计了一款基于嵌入式微处理器S3C2440A和WinCE 6.0系统的圆图无纸记录仪。该记录仪可根据现场要求改变模拟量和开关量输入输出,最多能够同时检测32通道模拟量输入,通道间采用PHOTOMOS隔离;同时配有CF卡、USB2.0、RS-232、RS-485和以太网等多种接口和触摸屏。该记录仪可通过各种总线形式与上位机(PC)联网,实现数据的实时监控和报警等功能。
In order to monitor the process parameters in productions of tire rubber and vulcanization directly perceived, and make up for the functional defects of existing circular chart recorders, the paperless circular chart recorder based on embedded microprocessor S3C2440A and WinCE 6.0 system has been designed. The recorder can change analog and discrete input and output in accordance with the requirement in the field and detecting up to 32 channels analog inputs; and PHOTOMOS isolation between channels is provided. In addition, multiple interfaces, e. g. , CF card , USB2.0, RS-232, RS-485, and Ethernet, etc. and touch screen are equipped. Thus, the recorder can communicate with host computer through various buses to implement real-time data monitoring, alarm and other functions.
