一种利用调制解调音频信号模拟惊吓驱离小动物的装置

A Device Using Modulation and Demodulation Audio Signal to Simulate Frightening and Driving Away Small Animals

当前,我国对于自然环境的保护力度越来越大,陆续颁布了一系列的政策,强调了保护自然的重要性,这在一定程度上促进了小动物数量的增加。而在郊区、山区建设的许多变电站,由于离城区较远,随着自动化技术的发展逐渐转为了无人值守变电站。由于人类活动减少,许多小动物都进入到变电站中,对变电站的运行造成影响。为了防止小动物对变电站运行设备造成的影响,文章提出了一种通过调制解调音频信号来驱离小动物的装置,具有成本低、驱离范围广、不扰民等特点,消除了变电站设备的重大隐患,保证了设备及人员的安全,能够大范围推广与实用。

Currently,China's efforts to protect the natural environment are increasing,and a series of policies have been issued in succession,emphasizing the importance of protecting nature,which has to some extent promoted the increase in the number of small animals.Many substations built in suburbs and mountainous areas,which are far from the urban area,have gradually become unattended substations with the development of automation technology.Due to the decrease in human activities,many small animals have entered the substation,affecting the operation of the substation.In order to prevent the impact of small animals on the operating equipment of the substation,the article proposes a device for driving away small animals by modulating and demodulating audio signals,which has the characteristics of low cost,wide driving range,and no disturbance to the people.It eliminates major hidden dangers of substation equipment,ensures the safety of equipment and personnel,and can be widely promoted and applied.
