Application Research On Multi-frequency Pseudo-random Astatic Rotary Magnetic Radiator

According to requirement of "high-yield food science and technology Projects" of the "11th Five-Year Plan" with national scientific and technological support, focusing on grain stockpile problem in rural areas, The paper hammers at a new physical method to expel and eradicate rodents. And it describes how to develop a set of pseudo-random astatic rotary electromagnetic field radiation system, which will be used in large or medium-sized grain depot to control grain postharvest losses.We have built our reasearch based on the injury influence of electromagnetic field radiation to the central nervous system, learning and memory capacity of rodents. And discussed the biomedical non-thermal effects and its influence mechanism, then represented how to generate our ELF signal and its advantages in bio.In the research and design of pseudo-random astatic rotary electromagnetic field radiation control system, pseudo-random broad-spectrum composite frequency signal source is used as man-made signal in deratization in storge environment for the first time. We developed a microcontroller genthered the pseudo-random number provided by DS1302, and controlled thyristor realization of the output spectrum of pseudo-random multi-frequency signal source. We use the land as the conductor, A realization of the double-dish astatic rotary electromagnetic fields by using grounding dipole, to radiate a larger area both aboveground and underground.By experiment, the equipment reaches design requirements.The pseudo-random astat The testing results show that the pseudo-random astatic rotary electromagnetic field has achieved the design requirements as 2～3Gs average,which was capable to open bio effects.The system is cheap, adapted, chronical, with a extensive prospect.
