多通道超声雾化器雾化率测试仪的设计

Design of multi-channels ultrasonic vaporware vapor ratio measuring device

智能化、多通道超声雾化器雾化率检测系统由三大模块组成:数据采集模块、控制器模块、显示模块。其中数据采集模块完成对来自多通道称重传感器的电压信号的检测、放大、AD转换。此时的数字信号送给控制器处理,由控制器完成对超声雾化器在单位时间内药水量的减少量的的判断、计算、显示等功能。此系统精度高,可靠性好,可以满足超声雾化器生产厂家和医疗器械监督局对超声雾化器雾化率合格率的测试要求,具有很好的实用价值。

This paper introduced a new type of intelligent multi channels ultrasonic vaporware measuring system. The design is made up of three modules：Data Sampling ＆ Processing, Main Controlling Device and Displaying Module. The data sampling and processing module finishes voltage single detection,magnification and AD conversion from multi-channels weigh sensor,then deliver control device processing,and finish accounting,displaying decrement of liquid medicine in ultrasonic vaporware device. This system design is of high precision and credibility.h suits demand of detecting manufacturer and medical treatment instrument supervise bureau quite well.
