摘要
目的:实现粮食产后减损,驱灭老鼠。方法:利用低频电磁场对鼠类生物效应研究的基础结合广谱复合频率信号的特性,以AT89S51单片机为依托提出了能发射出复合频率信号的伪随机广谱复合频率信号源的设计方案。结果:结果显示信号的广谱特性稳定而且该信号和其相应产生的电磁场的参数理论上能够满足实验的需要。结论:该信号源的设计是可行的,能够达到预期的目的。
Objective： To drive out or exterminate rats and decrease the loss of commissariat. Method： This paper put forward a broad-spectrum of pseudo-random composite frequency pulse signal source design basing on AT89S51 single chip microcomputer, combining the characteristics of broad-spectrum and complex-frequency signal and the research on the biologic influence of electromagnetic field to rats. Result： Simulative testing results appear the characteristics of broad-spectrum the signal is steady, moreover the parameter of the signal and corresponding electromagnetic field can meet the experhnent need in theory. Conclusion： The design of signal pulse is feasible and it can carry the anticipative point.
