摘要
目的研制发射极低频电磁波和超声波驱鼠装置。方法采用高性能的嵌入式单片机AT89C2051来控制超声频率和低频电磁波的发射,系统采用时钟芯片HT1380/1381,用于计时、提供时间基准和给单片机提供时间数据。结果通过实际检测,电磁波强度在10 m内稳定,磁场在15 m外有显著衰减,电场在20 m外有显著衰减。结论装置性能可靠,技术成熟,可在一定的范围动态变频同时发射极低频电磁场和超声波,可达到实用要求。
Objective To develop a rat repel device based on the technology of extremely low frequency （ELF） elec- tromagnetic waves and ultrasonic emitter. Methods A high-performance embedded microcontroller AT89C2051 and the clock chip HT1380/1381 were employed in the device. Results Electromagnetic wave intensity was stable within 10m m. Asignificant attenuation appeared in the magnetic field at 15 m,in the electric field at 20 m. Conclu- sion The device is reliable with mature technology. In a certain frequency range while dynamic extremely low fre- quency electromagnetic fields and ultrasonic wave were emitted, satisfying results could reached.
