The control system for Magnetic Resonance Sounding (MRS) groundwater exploration instrument was developed on the platform of LabVIEW. This system consists of transmission and reception sections. The former transmits current, controls power and acquires current and the latter controls amplifier, acquires MRS signals. In order to improve efficiency of data transmission, Ethernet based on TCP/IP is used in the system. Furthermore, the system has additional functions of pulse moment setting, equipment detection, data processing into pictures and data storage. Through outdoor experiments, it is found that the average error is less than 2%. The experimental results demonstrate the effectiveness and correctness of the system.

For the phenomenon of the college laboratory equipment mismanagement recent years, the RFID/ZigBee-based laboratory equipment remote management solution has been proposed. The hardware uses a ZigBee wireless network chip, an MSP430 low-power data processing chip and a WiFi data transmission module as the core, combined with various sensor and RFID technologies to perform information collection and transmission. The software is a web server developed in C# platform, using a three-tier structure to perform data storage, data access, and data processing. The experiments showed that it can perform communication between a monitoring terminal and a laboratory device timely and accurately, and achieve client integrate, and improve the efficiency of managing the laboratory equipment.

This research aims to make a warning light with a microcontroller base as a control system. With the aim of reducing the use of manual systems in general that are in use today. The advantage of this warning light control system is that it functions to reduce the number of accidents that occur and can be used for railroad crossings where there are still no latches that have not been installed on the railroad railroad crossing (wild road). The display of the work system that is made will be monitored using a web monitoring display that supports and is easy to understand. Even though it has some delay in the process, the planned system has run well based on the average delay value. The experimental results show the average delay measured in the system is 0.31 seconds before sending from the node and 0.49 seconds when there is a change in conditions, while when there is data transmission from the node. The measured packet loss on the system is 0% before transmission and fans and 8.88% when data is transmitted from the node.

Magnetic Resonance Sounding

Magnetic resonance sounding (MRS) is a geophysical technique developed for groundwater exploration. This technique can be used for investigating karst aquifers. Generally, the study of a karst requires a 3D field setup and corresponding multichannel data-acquisition instruments. Now only single-channel MRS equipment is available; i.e., the time needed for a 3D MRS field survey is multiplied by a factor of four or five. Where karst caverns are natural hazards, as in the Dead Sea coastal area at Nahal Hever, Israel, even an approximate localization of potentially dangerous zones and a corresponding estimation of the hazard dimensions are useful. We studied numerically the accuracy of MRS estimations of the volume of different 3D targets aroundNahal Hever, shifting a 3D target inside the MRS loop and calculating the volume-estimation errors for each target position. The calculations covered targets of different sizes. The size and position of a target being unknown factors in a field survey, the numerical data were considered as random values to be analyzed statistically. Using a 1D approximation of the MRS solution and assuming a [Formula: see text] MRS loop, the volume of a 3D target under Nahal Hever conditions is estimated within a [Formula: see text] error when the target is smaller than the MRS loop, and within a [Formula: see text] error when the target size is about the same as the MRS loop. The lower threshold of karst-cavity detection with MRS is about [Formula: see text]. For such estimation, only one sounding is required.

As the importance of vehicle data increases, it has become very important to safely store them. However, because onboard diagnostics scanners generally used to store vehicle data are IoT devices, security and capacity issues exist to store data safely and efficiently. To address this, we propose a system that stores vehicle data safely and efficiently using blockchain and IPFS. Users can access the system through DApp, an Ethereum-distributed application, and manage their vehicle data. Various experiments have been conducted to demonstrate the superior performance of this system, and the experimental results show its advantages in terms of data-processing speed and cost.
