Intelligent Mobile Trash can Based on Speech Recognition

This paper designs a smart home device with TMS320F2812 to achieve the purpose of voice control of garbage can movement. This paper introduces the overall scheme design, car body driving design, program design, speech recognition design, function module design, etc., and finally expounds the production and debugging process. For the recognition of specific speech, the system uses SPCE061A voice chip to process the collected voice; With the pickup as the sound sensor, the source orientation is detected in real time by using the delay estimation method, and the sound source location is carried out. In order to avoid the complexity of the circuit board brought by discrete components, the H-bridge driving component L298N chip is used in the design. Through this system, we can realize the intelligent garbage can, humanization, and make our daily life more convenient.
