The Design of a New Network Cabling Experimental Instrument Based on Embedded System
Structured Cabling is not a demonstrative course, but a course to stimulate students’ learning interest and to improve experiment’s efficiency. Unfortunately there are some disadvantages for experimental instruments on the present market, such as low testing speed, low automation level and less functions, etc. A multi-processor structure is proposed in this paper, which consists of a 32-bit ARM processor S3C2440 and a 8-bit Single Chip Microcomputer STC89LE54. This structure is used to develop a new network cabling experimental instrument, which is based on embedded system. The instrument can achieve precise processing, such as synchronous data acquisition for wire cores of 32 standard network lines according to EIA/TIA568A Standard or EIA/TIA568B Standard, display and data storage, etc. The instrument has characteristics of high efficiency, fast response, automatic identification, and ease of use. It is used to implement consistency between teaching and job training. Therefore it has high practical value.
