摘要
以激光光阻法颗粒计数传感器为基础,研制了液体颗粒在线检测仪。使用嵌入式计算机LPC2368作为核心,设计了数据接收、解析、显示和打印的硬件电路。编写了串口通信、数据解析和上位PC机的程序。检测仪可以检测并显示样品油液或水中4-70μm内不同粒径等级的微粒的个数,精度高、可靠性好。检测仪可保存大量数据,并可以现场打印重要数据。检测仪配有大容量电池,可长时间独立工作。检测仪还可与上位PC机进行通讯,导出数据,保存为电子文档。使用检测仪对样品油液进行了实际测量,系统运行正常,数据可靠。
The on-line measuring instrument based on liquid particle counting sensor was developed by laser extinction technology. A hardware circuit, using embedded computer LPC2368 as its core, was proposed for the data receiving, analyzing, displaying and printing. Programs for the serial communications, data analyzing and the upper computer were completed. This instrument can detect and show the particles＇ numbers of different diameter classes from 4 μm to 70μm in oil or water samples in high accuracy and reliability. It can save large amounts of data, and print the important data in field. It can work independently in a long time with a large-capacity battery, and can communicate with upper computer for exporting data and saving data in the style of electronic documents. The system works normally on the detecting of oil samples, and the results are reliable.
