Time to Digital Converters has been used to measure time difference between two events with high accuracy and resolution approx. 100 ps. In this paper, it is proposed to develop a data acquisition system for Time-of-Flight measurement using Time to Digital converter. The firmware for the system is designed around PIC 18F4550 microcontroller and TDC7200 integrated circuit. The system has been programmed to configure Time to Digital Converter using SPI line and log out the acquired data over to PC via UART. The readout system has been tested with calibrated delay inputs to examine the different working modes of operation. The gathered data has been analyzed using ROOT framework. The cost effective alternative for the Time to Digital Converter evaluation module also has been discussed and designed to be compatible with microcontrollers as well as Field Programmable Gate Array devices.

Developing a system which can be used for detection of faulty Integrated circuits (ICs) is one of the major challenge in electronic industry. Heating in ICs due to various reasons which may lead to degradation of performance and can cause serious hazardous effects in Printed Circuit Boards (PCB). Thermal image processing is one of the best non-contact, non-invasive method which can be used for IC fault detection. The paper aims towards detection of faulty ICs in PCB with help of thermal imaging camera and image processing techniques. Thermal images of sequence detector circuit for different fault conditions are collected. Image matching is achieved by comparing features of training images and test image using Speeded-Up Robust Features (SURF) algorithm. The system will indicate image belongs to particular fault class. The proposed method detects and classify possible faulty IC conditions with improved accuracy and can also help in early prevention remotely before complete circuit failure.
开发一种可用于故障集成电路检测的系统是电子工业面临的主要挑战之一。由于各种原因,集成电路中的发热可能导致性能下降,并可能对印刷电路板(PCB)造成严重的危险影响。热图像处理是集成电路故障检测中一种最好的非接触式、非侵入式检测方法。本文的目的是利用热像仪和图像处理技术来检测PCB中的故障集成电路。采集了不同故障条件下序列检测器电路的热图像。采用加速鲁棒特征(SURF)算法对训练图像和测试图像进行特征比较,实现图像匹配。系统将显示图像属于特定的故障类别。所提出的方法以更高的精度检测和分类可能的故障IC条件,并有助于在完全电路故障之前进行远程早期预防。

Solar energy is a renewable and clean source of energy and the easiest to utilize among all the other renewable resources available. Majority of the solar energy harnessing firms use panels made of a single junction solar cell for conversion of solar energy to electrical energy. With the advent of modern technology, multi-junction photovoltaic cells are made available. The multi-junction photovoltaic cells contain multiple P-N junctions within them. Due to these multiple junctions, heating of the cell is common which decreases the cell's efficiency. This is more prominent in certain concentrated photovoltaic systems and also may lead to permanent damage to the cell. The paper describes a cooling system design, which consists of a block on which the solar cell is to be mounted and water is made to flow in this block when the temperature of the cell exceeds beyond the maximum allowable temperature of the cell (60°C − 70°C), this temperature is measured by an infrared thermometer. The cooling system developed helps regulate the cell temperature and also assists in efficient working of the cell.
太阳能是一种可再生的清洁能源,也是所有可再生能源中最容易利用的。大多数太阳能利用公司使用由单结太阳能电池制成的面板将太阳能转换为电能。随着现代技术的发展,多结光伏电池成为可能。多结光伏电池包含多个P-N结。由于这些多结,电池的加热是常见的,这降低了电池的效率。这在某些聚光光伏系统中更为突出,也可能导致对电池的永久性损坏。本文介绍了一种冷却系统的设计,该系统包括一个安装太阳能电池的块,当电池的温度超过电池的最高允许温度(60°C - 70°C)时,使水在块中流动,该温度由红外温度计测量。开发的冷却系统有助于调节电池温度,也有助于电池的有效工作。

Wind turbine blades are huge structures, with complex design. Also, Blade is most complicated and costly component of a wind turbine. In present study mass of blade is reduced without increasing the stresses developed. For calculating aerodynamic loads acting on a blade of wind turbine BEM (Blade Element Momentum) theory is used. Tangential and Normal Aerodynamic loads are calculated for three different wind velocities i.e. 6, 8 and 10 m/s, In this study three dimensional modeling of blade is done using special wind turbine blade modeling software called Numerical Manufacturing and Design (NuMAD). The stresses developed at different critical points of turbine blade are obtained. The mass of turbine blade for different shear web configuration are also calculated. Using these values of stresses, optimal location of shear web is identified in MATLAB using genetic algorithm tool. The optimal locations of shear web are 55.18%, 55.84% and 55.27% and optimal mass of the blades are 2095.4 kg, 2105.1 kg and 2098.4 kg for the wind velocities of 6, 8 and 10 m/s respectively. The mass of the blade is reduced up to 1.02%.
风力涡轮机叶片结构庞大,设计复杂。此外,叶片是风力涡轮机中最复杂和最昂贵的部件。目前的研究是在不增加应力的情况下减小叶片质量。应用叶素动量理论计算风力机叶片上的气动载荷。计算了6、8和10 m/s三种不同风速下的切向和法向气动载荷。在本研究中,使用称为数值制造与设计(NuMAD)的专用风力涡轮机叶片建模软件对叶片进行了三维建模。得到了涡轮叶片在不同临界点处产生的应力。计算了不同剪切腹板结构下涡轮叶片的质量。利用这些应力值,利用遗传算法工具在MATLAB中确定剪力腹板的最优位置。风速为6、8和10 m/s时,剪切腹板的最佳位置分别为55.18%、55.84%和55.27%,叶片的最佳质量分别为2095.4 kg、2105.1 kg和2098.4 kg。叶片的质量减少了1.02%。

In today's world the rate of differently abled people is increasing day by day. According to the CENSUS 2011 it is showed that out of all disabilities, 20% are facing disability in movement. Wheelchairs have been the basic and most widely used aid for such people. But there are people suffering with partial paralysis or quadriplegia which affect their limbs. Thus, they need another person in order to assist the movement of the chair. A smart wheelchair is the best option in this case. A smart wheelchair is a powered wheelchair to which computers, sensors, and assistive technology are attached. We are proposing a smart wheelchair in which we use a head gear with a Gyro sensor to detect the head movement and will generate signals accordingly to move the chair. When head tilts towards the left the chair will move in left direction and similarly in forward, backward and right direction according to the movement of the head with the help of motors powered by a battery thereby eliminating the need for another person. This prototype will help such people to get rid of all the joysticks and controls and provides a convenient and economical solution bringing a sense of independency into their lives. Necessary precautions will be incorporated to ensure the safety of the person.
在当今世界,残疾人士的比例日益增加。根据2011年人口普查,在所有残疾人中,20%的人在行动中面临残疾。轮椅一直是这些人最基本和最广泛使用的辅助工具。但有些人患有部分瘫痪或四肢瘫痪,四肢受到影响。因此,他们需要另一个人来协助椅子的运动。在这种情况下,智能轮椅是最好的选择。智能轮椅是一种装有电脑、传感器和辅助技术的电动轮椅。我们提出了一种智能轮椅,我们使用带有陀螺仪传感器的头部装置来检测头部的运动,并相应地产生信号来移动椅子。当头部向左倾斜时,椅子将在电池驱动的马达的帮助下,根据头部的运动向左移动,同样向前,向后和向右移动,从而消除了对另一个人的需要。这个原型将帮助这些人摆脱所有的操纵杆和控制,并提供一个方便和经济的解决方案,给他们的生活带来独立感。将采取必要的预防措施,以确保人身安全。

Today images and videos are everywhere. In fact, the sheer quantity of images on social media and networking sites is unfathomable. Every device is now fitted with a camera. This opens up huge possibilities. Object Recognition is a process of detecting an object and identifying it using various image algorithms. The main purpose of this paper is to recognize objects in real time and allot the objects to the classes that are previously defined. The algorithms that we utilized are more computationally efficient. Previously, object detection was done using RFID and IR technologies which required dedicated hardware. But with the advent of image processing and neural networks, we require almost no new hardware. Almost everything has camera these days from pens to mobile phones. This has given rise to a new field called computer vision i.e. using pictures and videos to detect, segregate and track objects or events so that we can “understand” a real world scenario.
今天,图像和视频无处不在。事实上,社交媒体和网络网站上的图片数量是不可估量的。现在每个设备都配有摄像头。这带来了巨大的可能性。物体识别是利用各种图像算法检测并识别物体的过程。本文的主要目的是实时识别对象,并将对象分配给先前定义的类。我们使用的算法计算效率更高。以前,目标检测是使用RFID和IR技术完成的,这需要专用硬件。但随着图像处理和神经网络的出现,我们几乎不需要新的硬件。如今,从笔到手机,几乎所有的东西都有摄像头。这就产生了一个叫做计算机视觉的新领域,即使用图片和视频来检测、分离和跟踪物体或事件,这样我们就可以“理解”现实世界的场景。

Liquid Level Sensing using Lamb waves 基于兰姆波的液位传感
Pub Date : 2019-01-01 DOI: 10.1109/ICNTE44896.2019.8945890

The present study examines the possibility of using an ultrasonic guided wave technique for liquid level sensing. The setup consists of an Aluminium thin beam which is partly immersed in a liquid whose level is to be determined. When a wave guide is immersed in the liquid, guided wave in the waveguide is attenuated due to the leakage of its energy into the surrounding water. The amount of leakage is related to the characteristics of the waveguide and the surrounding liquid liquid. With these predictions, it is possible to relate the measured characteristics to the liquid level. Previous research shows that the various modes of Lamb waves are influenced by the surrounding liquid. Therefore, the change in the characteristic of Lamb waves can be used as a function of liquid level. This effect has also been investigated using Finite Element Analysis.
本研究探讨了利用超声导波技术进行液位传感的可能性。该装置由一根铝薄梁组成,该梁部分浸入待测液位的液体中。当波导浸入液体中时,波导中的导波由于其能量泄漏到周围的水中而衰减。泄漏量与波导和周围液体的特性有关。有了这些预测,就有可能把测量的特性与液位联系起来。以往的研究表明,兰姆波的各种模式受到周围液体的影响。因此,兰姆波特性的变化可以作为液位的函数。这种影响也用有限元分析进行了研究。

The setup consists of an Aluminium thin beam which is partly immersed in a liquid whose level is to be determined. When a wave guide is immersed in the liquid, guided wave in the waveguide is attenuated due to the leakage of its energy into the surrounding water. The amount of leakage is related to the characteristics of the waveguide and the surrounding liquid liquid. With these predictions, it is possible to relate the measured characteristics to the liquid level.

Online monitoring is the effective way to observe factual data. Internet of things based online monitoring is useful to access data remotely. IoT is the network of physical objects embedded with electronics, software and sensors that enable to collect and exchange data. IoT enables the flexibility and liberty to access the machine placed in a remote area access to keep a continuous track of the machine behavior in real time. Application of this technology in electrical engineering is beneficial to observe different parameters which are not easy to access. Electrical equipment performance can be monitored on a real time basis to improve the operating span. This is carried out using online monitoring system. IoT is used to observe different parameters on real time scale. This helps to measure and sense various parameters like energy, voltage, current, temperature, power factor and frequency of any given electrical equipment. This paper reviews suitability of IoT based online monitoring system for electrical equipment.
