单总线器件ID自动搜索和现场位置确定

ID Automatic Search and Position Locating of 1-Wire Devices

单总线是一种最简单的总线形式,它通过单线完成全部的控制、通信和供电,降低了网络测控系统布线的复杂性。单总线技术中的关键问题是单总线网络中从机器件的ID识别。在实际应用中,当识别了器件ID后,确定器件在测量现场的位置就成为关键问题。本文重点介绍一种单总线中从器件ID的自动搜索和现场位置的确定方法。

1-Wire Bus is the simplest form of Bus. It completes control, communications and power supply all through one wire, so it reduces the complexity of cabling of the network monitoring and control system. The key issue is to identify the ID of slave devices of the 1-Wire network in 1-Wire Bus technology. In practice, position locating on the spot of the devices becomes the key issue after identify the ID of all slave devices on the bus. This paper mainly introduce one method to identify the ID of all slave devices and determine the position.
