"创新设计红外避障传感器：超长距离、免受光干扰，智能机器人必备"

随着现代技术的不断发展，传感器技术在各行各业中起着至关重要的作用。在传感器类型中，红外避障传感器被广泛应用于生活中，尤其在各类电子竞赛中更是不可或缺的一种传感器。然而，一般未经调制的红外避障传感器存在着检测距离较短、易受自然光干扰等问题，这对于需要使用红外避障传感器的智能机器人等设备来说就显得不够理想。因此，设计一款能够检测距离达到200cm以上，并且不受自然光干扰的红外避障传感器变得十分必要。 在本次基础工程设计课程中，我们将着重研究红外避障传感器的原理、特点以及现有问题，并提出一种改进设计方案。通过调制等手段，我们旨在提高红外避障传感器的检测距离，降低受自然光干扰的程度，从而使其更加适用于各种实际场景。通过本次课程设计，我们不仅可以深入了解传感器技术在工程领域的应用，还可以提升我们的设计能力和解决问题的能力。 关键词：红外避障、调制、自然光干扰、检测距离 Abstract With the development of modern technology, sensor technology has become increasingly indispensable in various industries. Among the types of sensors, infrared obstacle avoidance sensors are widely used in daily life, especially in various electronic competitions. However, unmodulated infrared obstacle avoidance sensors generally have short detection distances and are easily affected by natural light interference, which makes them less than ideal for devices such as intelligent robots that require the use of infrared obstacle avoidance sensors. Therefore, it becomes necessary to design an infrared obstacle avoidance sensor that can detect distances of over 200cm and is not affected by natural light interference. In this basic engineering design course, we will focus on researching the principles, characteristics, and existing problems of infrared obstacle avoidance sensors, and propose an improved design solution. Through modulation and other methods, we aim to increase the detection distance of the infrared obstacle avoidance sensor and reduce the degree of interference from natural light, making it more suitable for various practical scenarios. Through this course design, we can not only gain a deeper understanding of the application of sensor technology in engineering, but also enhance our design and problem-solving abilities.
