在机器人应用中常常需要检查外界声音的音量值,但传统的基于硬件的方案成本高、可靠性差,效果不能让人满意。为此,笔者在研制一款噪音监测机器人时别出心裁,发明了一种用于音量检测的创新方案,该方案具有电路简单、成本低、易于调试、性能稳定的优点。 In robotic applications, it is often necessary to check the volume of the external sound, but traditional hardware-based solutions have high cost, poor reliability and unsatisfactory results. To this end, the author in the development of a noise monitoring robot ingenuity, invented an innovative solution for volume detection, the program has a simple circuit, low cost, easy debugging, the advantages of stable performance.
