【摘要】：鼠害是一个很严重的世界性问题,老鼠的一举一动都可能给人类带来危害。为了控制鼠类的危害,人们采取器械(鼠笼、鼠夹等)、陷阱、粘鼠板、建筑与设施防鼠、化学杀鼠剂、天敌等多种措施与鼠类抗争。本论文利用新型电力电子器件和适于更高开关频率的电路拓扑，设计出一款能发出大功率、变频式的超声波驱鼠器，并将其合理安放在鼠患严重场所，以此达到驱鼠目的。电力安全生产的重要性是由电力生产、电力基本建设、电力多种经营的客观规律和生产特性及社会作用决定的。随着电力工业迅速发展、电力体制改革和市场化进程加快，电力安全生产的重要性更加突出，而鼠患对电力系统会造成不可估量的危害，本论文根据电子驱鼠器的工作机理和使用技术，采用多种统计方法进行现场驱鼠试验。试验结果表明，不同频率、声压的超声波对驱鼠效果有较为明显的影响，其表现为：首先在同一声压条件下频率越高，鼠密度越低，驱鼠效果越明显；其次，在同一频率条件下声压越高，鼠密度越低，驱鼠效果越明显。此外，研究发现当长时间使用某一特定频率进行驱鼠时，老鼠对该特定频率具有一定的适应性，表现为鼠密度上升到接近原来水平。本文在总结前人研究的基础上，深入探究超声波频率、声压对鼠类动物日常生活的影响以及老鼠对某一特定频率的适应性周期的研究，并分析总结最佳驱鼠方案，最后推广到家庭、商业和安全生产等领域的驱鼠中，为人类的生活、工作及健康安全提供保障。
[Abstract]:Rat damage is a serious worldwide problem. Every move of a mouse can cause harm to human beings. In order to control the harm of rodents, people take various measures to fight against rodents such as cages, traps, traps, stick plates, buildings and facilities for rodent control, chemical rodenticide, natural enemy and so on. In this paper, a new power electronic device and circuit topology suitable for higher switching frequency are used to design a high-power, variable-frequency ultrasonic rat repellent device, which can be reasonably placed in a severely rodent place, so as to achieve the purpose of rat repellent. The importance of electric power safety production is determined by the objective law, production characteristics and social function of electric power production, electric power capital construction, electric power diversified operation. With the rapid development of the electric power industry, the reform of the electric power system and the acceleration of the marketization process, the importance of the electric power safety production becomes more prominent, and the rodent plague will cause incalculable harm to the power system. According to the working mechanism and application technology of electronic rat repellent, this paper adopts various statistical methods to carry out field rodent repellent test. The experimental results show that ultrasonic wave with different frequencies has a significant effect on the rodent repellent effect. Firstly, the higher the frequency under the same sound pressure, the lower the rat density, the more obvious the repellent effect is, and the second is that the higher the frequency is under the same sound pressure, the lower the rat density is. At the same frequency, the higher the sound pressure, the lower the rat density, and the more obvious the repellent effect is. In addition, it was found that when a specific frequency was used for a long period of time, the mice had a certain adaptability to the specific frequency, which showed that the density of the mice increased to the original level. On the basis of summarizing the previous studies, this paper probes into the effects of ultrasonic frequency, sound pressure on the daily life of rodents and the adaptive cycle of mice to a certain frequency, and analyzes and summarizes the best rodent repellent scheme. Finally, it is extended to rodent repellent in family, business and safe production, which provides guarantee for human life, work, health and safety.
