Abstract

The invention discloses a method and a system for quickly searching a serial number of a single-line device on line. In a test process, a formal code is generated and sequentially transmitted to a bus. Therefore, the serial number of a device is obtained. The formal code is the obtained serial number.The formal code is generated. A preparatory code is generated. The preparation code is not the serial number of the device. However, the generation of the next formal code can be guided. Therefore, the host can identify all the devices on the bus only by a very small number of times, whether searching is completed or not can be judged without additionally testing the bus, the serial number can be automatically generated in the searching process and used by the host, manual input is not needed,the workload of manufacturing and maintenance can be reduced to a large extent, and the practicability is high.

Description

technical field [0001] The invention relates to the application field of single-wire bus device networking, in particular to a method and system for quickly searching the serial number of a single-wire device online. Background technique [0002] Single-wire (1-Wire) devices are products of Dallas Semiconductor Corporation in the United States. It is a series of integrated circuits that realize interconnection and communication based on a signal line. Single-wire devices are easy to realize automatic control networks such as industrial field temperature collection and switch value control. As of 2011, there are more than 30 single-wire devices, including DS1820 (temperature sensor), DS2405 (switch), DS2450 (A / D converter) and so on. The single-wire bus is a simple signal exchange method, which is a two-way communication between the host computer and the peripheral device through a line. All single-wire bus devices have a common feature: each device has a fixed 64-bit bina...
