ABSTRACT
In recent years, with the continuous development of social economy, the continuous expansion of urban scale, and the continuous improvement of people’s consumption level, the total amount of garbage generated in urban life has also been increasing, resulting in increasingly serious environmental pollution problems, which need to be solved. As a tool for storing waste, garbage bins are being applied in urban household waste management systems. Not only are classified garbage bins widely used, but intelligent garbage bins are also developing rapidly. Their emergence greatly facilitates the cleaning of sanitation workers and effectively reduces the impact of waste on the environment. The emergence of intelligent garbage bins is also accompanied by breakthroughs and developments in high-tech. For any high-tech product, it should have a certain degree of practicality, and how to develop a high-performance, low-power consumption, and long service life practical product at the lowest cost is the focus of this design research.
Firstly, in order to develop a multi-functional intelligent garbage bin based on speech recognition, this design explicitly uses the microcontroller STM32F103C8T6 as the intelligent control center, combined with a separate infrared ranging module (garbage volume detection), an infrared obstacle avoidance tube module (detecting whether there are people), a smoke detection module (fire occurrence), a temperature detection module (fire sending), a motor module (controlling the opening and closing of the garbage bin lid), and an alarm module, The OLED intelligent display module, speech recognition broadcast module, disinfection module, and peripheral auxiliary circuits form a multifunctional intelligent garbage management system based on speech recognition. Secondly, determine the device scheme selection, hardware circuit schematic design, and program control code writing and burning for each module, in order to verify the expected intelligent voice trash can function. The system is a control board with STM32 as the core. When a user says a wake-up word such as “Xiaozhi Xiaozhi”, the speech recognition chip SU-03T starts the recognition program to recognize the keywords that the user switches the trash can. STM32 sends instructions to control the rotation of the corresponding servo, achieving the opening and closing of the trash can lid, and achieving basic voice control of the trash can switch function. At the same time, through the design of the system control algorithm and the processing of data signals, Under the function of the built-in sensor in the garbage bin, it can intelligently detect the capacity, temperature, and smoke concentration of the garbage in the bin in real time, and display it on the intelligent OLED display screen. When the garbage bin is detected to be full, it will give an alarm reminder to achieve the goal of full bin warning. In addition, infrared obstacle avoidance can be used to identify whether someone is currently present and detect someone automatically controlling the trash can. Finally, test each module and the entire machine to ensure the reliability and stability of the product. After testing, this design can achieve speech recognition and automatically control the opening and closing of the trash can. The servo can execute the opening and closing actions of the trash can according to the established program design when triggered by the speech recognition results. The data flow transmission and software system can meet the design functional and performance requirements, thereby ensuring the reliability and practicality of this multifunctional intelligent trash can based on speech recognition.
