基于Android系统的微型光谱仪数据传输及图形化显示

为了满足光谱仪数据采集显示一体化、操作控制智能化的要求,提出了一种基于Android系统的微型光谱仪数据传输及图形化显示的设计方案。该方案是在Android系统平台上进行光谱仪数据采集与嵌入式设备间的串口通信,将采集得到的数据以光谱图的形式显示,并支持数据及图片的保存功能。实验结果表明,该光谱仪可以在Android系统下以115 200bit/s的速度高效采集光谱数据,实时地将数据以光谱图的形式显示出来,并支持数据保存及读取的操作。

Design of a miniature spectrometer data transmission and graphical display based on the Android system

In order to meet the need of the integration of spectrometer data acquisition, display, intelligent operating and controlling, a designing scheme about miniature spectrometer data transmission and graphical display based on the Android system is introduced. The spectrometer is employed to communicate between data acquisition system and embedded device by serial port based on the Android platform. Then the collected data will be displayed in the form of a spectrum chart, and it also supports saving data and picture. The experimental results show that the spectrometer graphical interface can efficiently collect spectral data under the Android system at the speed of 115 200 bit/s, real-time display the data in the form of spectrum chart, and it can also support data storage and data read operation.
