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.

For the caused harvesting loss problem by inaccurate alignment of the semi-feeding peanut harvester, an automatic alignment system on the control core of the single chip microcomputer μPD78F0525 was designed. The system adopts a four-bar detection mechanism to transmit the offset to the controller through the sensor and to adjust the excavator in time. On this basis, a peanut automatic alignment test device is developed, which is composed of conveying platform, ridge ditch, hydraulic execution system, signal detection mechanism, signal processing and control system, etc. The influence effect of the main factors of the system is tested through the test bench. The results show: the reaction time increases with the increase of spring preload and deviation distance, gradually decreases and tends to remain unchanged with the increase of forward speed, and first decreases and then increases with the increase of hydraulic flow. The unqualified rate first decreases and then increases with the increase of spring preload, gradually increases with the increase of forward speed and deviation distance, and gradually decreases with the increase of hydraulic flow. The effectiveness and stability of the automatic alignment system can meet the operation requirements. It effectively solved the problem of automatic alignment of the semi-feeding peanut harvester and provided a technical reference for the research and development of the automatic alignment system for harvesting the fruits under the soil.
