Internet-of-things-based four-dimensional high-density electrical instrument for geophysical prospecting

The high-density electrical method is a primary method used in shallow geophysical prospecting. Due to the rapid industrial development that has taken place in recent years, the function and performance of high-density electrical instruments have been considerably improved in several aspects. However, most of the electrical instruments currently available on the market still exhibit some shortcomings, such as being bulky, heavy, limited in their data acquisition accuracy, and difficult to connect to the Internet for remote monitoring. To address these problems, this study developed a new multifunctional four-dimensional (4D) high-density electrical instrument based on remote wireless communication technology. The system is small and lightweight, includes an integrated transceiver, has high data acquisition accuracy, and is capable of remote wireless real-time control. In this study, the hardware circuit was designed. The Arm all-in-one (AIO) LJD-eWinV5-ST7 with a 154.4 cm × 87 cm, 800 × 480 high-brightness wide-temperature-range display is used as the host computer, which has the advantages of small size, low power consumption, and abundant hardware resources. Internet of things (IoT) technology is incorporated in the system, and a 4G module is employed to provide a real-time remote control and data acquisition monitoring system based on the cloud platform. Tests showed that this instrument is stable and convenient to use and can meet the requirements for use in field prospecting.

A Sensor based IoT Monitoring System for Electrical Devices using Blynk framework

Electrical device monitoring is an essential work for improving the efficiency of electrical energy. The industrial device monitoring process are majorly contributed with physical verification of the process going on with the electrical instrument. In some cases the monitoring work is handled with help of automated sensor controllers. The automated sensor controllers are widely used for emergency cases of the ongoing process by the electrical instruments. The system status will be displayed on a screen when the system is fully controlled by an intelligent controller. From the status certain process and equipment are able to manage by physical switches by a human operator. The proposed work is designed to control certain applications which are remotely placed from the control station. The design utilizes internet medium and Blynk server for the specific operations. A sensor based monitoring station is kept near to the electrical device for sending the status of the application system. By using this design any system can be monitored remotely without physical verification. This improves the efficiency of energy utilization by the control devices.

Design the Integrated Multipurpose Instrument Calibrating Equipment Based on the PXI and LabVIEW

According to the function, the technical indexes and the cost control etc, we select the embedded control computer and virtual instrument module based on the PXI, and developed the integrated multipurpose instrument calibrating equipment, it realized the field measurement and calibration of the electrical instrument away from the laboratory. The system is designed based on PXI and LabVIEW, it uses virtual instrument technology, automatic control technology and database technology, by combining these functional modules of NI, we realized the calibration of electrical instruments such as digital multimeter, signal generator, oscilloscope and cymometer etc. The system is used integrated design, and it is very flexible, it can be popularized and applied as working standard to troops, factories or schools etc.

A simple atmospheric electrical instrument for educational use

Electricity in the atmosphere provides an ideal topic for educational outreach in environmental science. To support this objective, a simple instrument to measure real atmospheric electrical parameters has been developed and its performance evaluated. This project compliments educational activities undertaken by the Coupling of Atmospheric Layers (CAL) European research collaboration. The new instrument is inexpensive to construct and simple to operate, readily allowing it to be used in schools as well as at the undergraduate University level. It is suited to students at a variety of different educational levels, as the results can be analysed with different levels of sophistication. Students can make measurements of the fair weather electric field and current density, thereby gaining an understanding of the electrical nature of the atmosphere. This work was stimulated by the centenary of the 1906 paper in which C. T. R. Wilson described a new apparatus to measure the electric field and conduction current density. Measurements using instruments based on the same principles continued regularly in the UK until 1979. The instrument proposed is based on the same physical principles as C. T. R. Wilson's 1906 instrument.
