摘　　要：1Wire总线是一种适用于温度和模拟量监测的总线,并具有优良的性价比,是在BESⅢ慢控制系统设计中应用较广的总线。USB具有热插拔、易扩展、占用系统资源少等优点,广泛应用在计算机与外围设备的连接上。结合BESⅢ慢控制系统的要求,介绍了基于USB接口的1Wire总线控制器1WireBus-USB的软硬件设计与实现。1Wire bus, which is wildly used in the design of BESⅢ Slow Control System, is a king of bus with excellent cost performance for monitoring temperature and analogy. USB has many good qualities such as supporting hot-plugging, easy to extending and not occupying less system resources, which is wildly used on computer. Based on the requirement of BESⅢ Slow Control System, the design and realization of 1WireBus-USB that is a bus master for 1Wire bus is introduced in this paper.
