摘要
目前市面上主流驱鼠和驱虫器多是利用模拟电路实现超声波信号、电磁波信号,以及音频信号的输出,但是信号的频率和输出方式固定,驱赶对象较为单一,而且长期使用后,容易使驱赶对象对信号产生适应性。本文针对该问题,提出将超声波、电磁波,以及音频进行智能融合,一方面提高驱赶对象的多样性,另外一方面避免驱赶对象对信号产生适应性。本文以意法半导体公司的超低功耗STM8单片机为核心,设计了系统电路,并对算法进行了实现。经辽宁省疾病预防控制中心检测,使用该装置后,在规范的测试场所,鼠类摄食行为下降了20.57%,测试结果较好地验证了本设计方案的可行性。
At present, the mainstream mice and pest repellers mostly use analog circuits to implement ultrasonic signal, electromagnetic wave signal, and audio signal output. But their frequency and output method of the signal are fixed, and their driven targets are single. Besides, they are easy to make the driven targets adapted to signal after long time use. Aiming at this problem, a way of multi signal intelligence fusion by ultrasound, electromagnetic wave, and audio is proposed in this paper. On the one hand, it can enhance the diversity of driven targets, on the other hand it can also avoid the targets adapted to the signal. This paper designed the system circuit and implemented its algorithm with the core of ultra-low power STM8. After estimated by Liaoning center for disease prevention and control, the mice ingestion behavior decreased by 20.57% after using the device in the standardized test site, which proved the feasibility of the design.
