This research presents a high-precision 3D surface defect detection system, which can evaluate the defect of the detected object accurately and quantitatively. As shown in Fig. 1, the implementation logic of this proposed system is to first carry out system calibration, then to perform 3D reconstruction and point-image relationship …
Small defects on the rails develop fast under the continuous load of passing trains, and this may lead to train derailment and other disasters. In recent years, many types of wireless sensor systems have been developed for rail defect detection. However, there has been a lack of comprehensive reviews on the working principles, …

H. L. Lu et al. DOI: 10.4236/oalib.1108265 5 Open Access Library Journal Figure 2. DS18B20 temperature sensor. Figure 3. Voltage and current detection module. is a 128× 64 dot matrix. Each dot can emit light, so it has no backlight. It can display Chinese
Battery management system
The identification and location low-level DC ground fault current has historically been difficult and caused multiple systems power interruptions. With this use of new technology, this process has been simplified in some ways, but a greater understanding of the complexities of your DC system is needed by the users of the newer generation …

They detect various fire indicators like smoke, heat, infrared light, or gas, providing early warning to evacuate and minimize damage. These detectors can be standalone units or integrated parts of a larger fire alarm …
Fault detection of the electric vehicle battery system is vital for safe driving, energy economy, and lifetime extension. This paper proposes a data-driven …
Conventional or "point wired" fire detection and alarm systems were for many years the standard method for providing emergency signaling. In a conventional system one or more circuits are routed through the …
In this paper, the current research progress and future prospect of lithium battery fault diagnosis technology are reviewed. Firstly, this paper describes the fault types and principles of battery system, including battery fault, sensor fault, and connection fault.
A rain sensor is one kind of switching device which is used to detect the rainfall. It works like a switch and the working principle of this sensor is, whenever there is rain, the switch will be normally …
Ground fault monitoring solutions must be approached differently in ungrounded systems vs. solidly grounded or resistance-grounded systems. In ungrounded systems, the best practice is to actively monitor the "strength" of the insulation system to ground, even
Introduction. The amount of energy that can be extracted from lithium-ion batteries (LIB) is related directly to the voltage levels that are spanned in the course of …
Accurate detection and diagnosis battery faults are increasingly important to guarantee safety and reliability of battery systems. Developed methods for battery early fault diagnosis concentrate on short-term data to analyze the deviation of external features without considering the long-term latent period of faults. This work proposes a novel data …
However, there is a shortage of universal, practical, and effective system design theories and solutions for DC arc-induced battery thermal runaways and thermal …
