摘要
根据Kretschmann型表面等离子共振传感系统的需要进行设计,实现基于C51单片机,包括上位机、4×4键盘和1602液晶功能等多种用户交互方式的硬件控制系统。使用C语言编写单片机控制程序,实现键盘和液晶显示操作控制功能,并操作步进电机进而控制传感器入射光角度,还通过串口转RS485控制泵和阀进而精确控制样品的注入。上位机上编写了与单片机通信的Labview串口通信程序,单片机接收处理指令,实现了上位机上的传感器入射光角度控制。提供了全面易用的表面等离子共振传感器系统功能。
A hardware control system based on Microcontroller（MCU） is designed for a Kretschmann Surface Plasmon Resonance sensing system in this paper.It comprises of PC,4×4 keyboard and 1602 LCD and other user interface functions;The control program on MCU is designed by C language,including keyboard,LCD,the sensor＇s incident light angle,and sample injection through the Serial Communication interface.Meanwhile Labview program on the PC send the incident light angle control commands to MCU and receive the feedback information.It provides users with a comprehensive and easy-to-use Surface Plasmon Resonance sensor system functions.
