| 摘 要： | 提出一种新型环境参数监测仪,基于USB HOST技术设计,嵌入式USB主机系统采用SM5964单片机加上USB主从芯片CH375的结构,实现USB1.1主机协议和USB mass storage类,从而通过对U盘的各种操作将采集到的环境参数(声音响度、温度)存入U盘,以其为媒介向上位机完成数据反馈。应用实践证明,该仪器广泛适用于居民小区、交通要道等不同环境下,且简易便携,有较好的市场前景。

| Abstract: | This paper discusses a new kind of environment inspecting appartus which applies the technique of USB HOST.The constitution of embedded USB HOST system,for the implement of USB HOST specification 1.1 and USB mass storage class,adopts SM 5964 microcontroller and CH375 which is an embedded USB Host/Slave controller,thus the embedded USB HOST has the information(sound and temperature) measured from environment and stored in USB dish by its operation,and then feeds the data back to the upper pc.It's proved that this instrument applies to the different environment like habitation,traffic and so on.For facility and portability,it has preferable marketability. |
