降水现象仪模拟软件设计与实现

Design and Implementation of Simulation Software for Precipitation Phenomenon

激光雨滴谱仪有代表性的就是德国研制的Parsivel激光雨滴谱仪,该仪器性能优良,已商业使用,但毕竟是国外的。针对国内科学研究雨滴谱仪器技术不成熟的问题,停留在实验室阶段,而一般的雨滴谱仪在速度控制方面又做的不够好,文章仅在模拟雨水降落速度问题研究上,在.net平台利用c#设计了在一种利用Serial Port组件(类)控制电机速度模拟降水速度的降水现象模拟软件,将实际降水天气现象时的雨速大小作为标准,进而修正电机速度,达到逼近真实天气现象的效果,进而后续的科学研究,软件设计充分利用了.net(winform)平台的界面友好性,以及该平台下丰富的类库,通过设置电机参数,按照电机说明书通过串口指令可以获取电机的配置参数,如PID参数,软件通过封装这些参数,按照相应的指令格式将参数利用所写模拟软件通过串口通信方式传送给电机,达到修正电机的速度问题。详细阐述了对电机控制的原理及方法,并对软件涉及到的一些技术点作了一些简要说明,软件小巧灵活方便,运行稳定。

The representative laser raindrop spectrometer is Parsivel,which developed in Germany,the instrument has good performance,commercial use,however,it is abroad. The domestic science and technology is not mature on raindrop,staying in the laboratory stage,and general raindrop spectrometers in the speed control is not good enough. To solve this problem,only in the simulation of rain on speed,the author designed a simulated rainfall simulation software using c# and Serial Port components（ classes） in Net platform to simulate precipitation velocity through controlling rotation rate of motor. The rain rate size in actual precipitation weather phenomenon is used as a standard. And then fix the motor speed to close to the real weather phenomena and do further scientific research. The software make full use of userfriendly interface of the.net platform（ winform）,as well as the rich class library,by setting the motor parameters,according to the machine manual instructions can obtain configuration parameters,such as the PID parameters,the software by encapsulating the parameters and using the simulation software through a serial port communication mode sending to motor,which can achieve correction motor speed problem. The principle and method of motor control are described in detail. And some technical points related to the software are briefly described. The software is compact and flexible,and the operation is stable.
