摘要
针对光电检测系统中采用电位计于实验现场手动调节光电倍增管(Photomultiplier Tube,PMT)模块增益时存在的操作不便、误差较大等问题,设计了一种PMT模块增益调节的控制系统。该系统硬件电路包括FPGA、DA模块以及串口通讯模块;上位机软件包括串口参数设置模块、控制电压调节模块、电压校验模块,可以实现数据的发送、存储、与硬件电路通讯等功能。实验结果表明,该系统可实现PMT模块增益的远程调节,操作便利、稳定性好、可复用性较强,具有很好的实用价值。
Aiming at the problem of manual gain adjustment of Photomultiplier Tube（PMT）module by using potentiometer at the experimental site,in which the gain of the module is inconvenient and the error is large,a PMT module gain adjustable control system has been designed.The hardware circuit of the system included FPGA,DA module and serial communication module.The host computer software included the serial port parameter setting module,the control voltage regulation module and the voltage check module,and it could realize data transmission,storage,communication with hardware circuit and so on.The experimental results show that the system has good practical value,which can realize remote adjustment of PMT module gain with good stability and reusability.
