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.

Abstract In order to meet the needs of operation and management of stepping motors in the Internet of things environment, this paper designed the software and hardware of the stepping motor drive system under the control of a single-chip microcomputer based on LabVIEW, which is a graphical programming platform developed by National Instruments Corporation of the United States, and tested and verified the functions of the system. The software part transmitted data between the host computer and the driver terminal based on a service cloud platform called Easy-Control, realizing the network real-time online management operation function. The hardware design made full use of the existing functions of the STM32F407ZGT6 single-chip microcomputer; moreover, the design of circuits was simplified by the special driver chip LV8726TA for stepping motor to increase system stability. The software and hardware of the system were developed on the LabVIEW platform, which had the advantages of high efficiency, short development cycle, low cost, and convenient function expansion. This work provides a scheme for the design and implementation of similar systems.

The DC system is used as the power supply for all kinds of protection, measurement and control, safety automation and other devices in the substation. It is the fundamental guarantee of power system control and protection. If the substation DC system fails, it will have a destructive impact on the entire substation system and function. Based on this, in order to solve the problems of maloperation and refusal of protection device caused by grounding fault of DC system, a method combining unbalanced bridge method with leakage current sensor is proposed to detect the grounding resistance of bus and branch. On this basis, the neural network optimized by quantum particle swarm optimization is used to determine the fault type. Finally, the effectiveness of the proposed method is verified by MATLAB/Simulink simulation.

As the sunlight must illuminate the optical fiber in a certain angle in the fiber optic lighting system, a sunlight collecting machine is designed. It uses the 3DU51 light activated triode to transform the changes of sunlight's intensity which is caused by the position of the sun into electrical signals. And after the processing of ADC0809 converter, the signal is sended to AT89S51 single-chip microcomputer which will produce electrical signals to control the electromagnetic relay switches closed or disconnected, realizing that the driving motor can be controlled to start rotating and stop rotating automatically. So the sunlight collecting machine can track the position of the sun, collecting the most strong direct sunlight, improving the system's efficiency of collecting sunlight.
