Information Monitoring of Transmission Lines Based on Internet of Things Technology

To solve the problem of difficult real-time monitoring of current transmission lines, this article proposes an information-based monitoring system for transmission lines based on Internet of Things technology. The system utilizes the characteristics of strong scalability, good fault tolerance, low power consumption, and low cost of the Internet of Things. Taking the ultra-low power consumption MSP430 microcontroller and CC2430 radio frequency module as the core, a line monitoring system based on the Internet of Things is designed. The proposed design uses ZigBee wireless sensor network technology which is powered by solar energy. The collection, transmission, processing and judgment of various environmental parameters of the line are realized. The data information is transferred to the monitoring center of the upper computer through GPRS. When there is an abnormality, it can send a mobile phone short message to the person in charge to feedback the abnormal content in time. The distribution network's load symmetry allowed for the development of several locating procedures. For the three-phase symmetric scheme, the fault location approach based on line supply characteristics was employed, and for the three-phase asymmetric scheme, the fault location technique based on line impedance is proposed. One of the most vital uses for the Internet of Things is in the mitigation of power transmission line failures and disasters. Improved power transmission dependability, less financial loss, and fewer power outages are all possible thanks to the Internet of Things' cutting-edge sensing and communication technology. This research introduced the use of IoT in online monitoring system of electricity transmission line with a focus on the characteristics of the construction and development of smart grid. The results indicated that the system's highest temperature difference is 0.31 C, while the maximum humidity difference is 1.38%. The system increases the safety and manageability of electricity transmission while also fostering the widespread adoption and technical integration of the smart grid and the Internet of Things.

The mechanism of the proposed system is classified into three stages: data collection, data processing, and information monitoring. To understand an Intelligent Indoor Environmental Monitoring, first, we collected the gas from Intelligent Indoor Environmental Monitoring through the environmental sensors with ZigBee wireless sensor network technology. We build a platform for iDEMS to collect the data related to the indoor gases. Second, the environmental data collected in the first stage will be stored and processed in HBase which support massive data storage and free to increase storage capacity for the analysis and processing of Big Data. In this stage, we also compared several data-input methods to import data in HBase much more efficient. Third, the intelligent-control socket is integrated into iDEMS and give the warning if the air quality exceeds the absolute legal limit based on the air quality index rule from the authority. Finally, iDEMS presents the resulting information by a web-based Monitoring Platform so that users can use the Internet to monitor the environment and enable them to utilize these informed decisions on managing and improving the environments.

ZigBee based multi-purpose electronic score design and implementation using EOG

This study uses ZigBee wireless sensor network technology to build a Multi-purpose Electronic Score system based on the electro-oculogram (EOG). As a requirement when learning to play a musical instrument the most commonly seen scores are available in paper copies. The disadvantage of the paper music score is that pages must be turned manually by the performer while playing music. An alternative is to prepare a miniaturized copy of the score, but this makes the score difficult to read clearly. Electronic scores have recently become available and are expected to become mainstream in the future due to the rapid growth in ebook readers and tablet PCs. Tracking the upward, downward, leftward, rightward and clockwise/counterclockwise eyeball movements and eye blinking, an amplified, bandpass filtered electro-oculogram (EOG) signal is converted into digital form. This signal is further transmitted through a ZigBee wireless module on which an electronic score program is installed, including the following operating modes; go to the previous/next page, recording, tuning and tempo modes. Detected eyeball movements allow a score to be viewed conveniently while playing. In the future, the proposed technology can be applied to flexible paper, flexible displays and the like.
