中文摘要: |
通过语音识别技术在电梯系统的应用研究,文章提出一种具有语音识别功能的电梯外招串行通信板的设计,其
以STM32作为主控制芯片,结合LD3320语音识别集成芯片,加入软硬件抗干扰设计,应用于电梯各层门厅外招系统中,
能够通过语音方式实现呼梯。经过实践测试,系统工作稳定,实时性良好,通信信号稳定。在安静环境下,呼梯识别率约
达90%;在嘈杂环境中,呼梯识别率还有待进一步提高。 |
英文摘要: |
Through the research of speech recognition technology to be applied in the elevator system, a designing of
serial communication board of outside calls of elevator with speech recognition was presented. A MCU of STM32 as the
main control chip coordinated with an integrated chip of speech recognition of LD3320. It was designed with anti-
jamming of hardware and software. and worked well for speech recognition that applied in outside call system of elevator
in each floor foyer. By the practice test statistics, the system is stable. and the timeliness is good, and also the
communication signal is stable. The recognition rate is about 90% in a quiet environment. and it should be further
improved in a noisy environment. |
