The goals of this research are to design a 3D printed environmental data logger while considering sensor packaging space constraints and to implement a smart power consumption system for increased endurance. The product is sealed for harsh environmental conditions per IP65 standard as well as for impacts. In this paper, we share our electronics packaging design approach for a mobile sensor suite so...
In this paper, we consider a scenario where an energy harvesting sensor continuously monitors a system and sends time-stamped status updates to a destination. The destination keeps track of the system status through the received updates. We use the metric Age of Information (AoI), the time that has elapsed since the last received update was generated, to measure the “freshness” of the status information...
The inherent complexity of Wireless Mesh Networks (WMNs) makes management and configuration tasks difficult, specially for fault detection and diagnosis. In addition, manual inspections are extremely costly and require a highly skilled workforce, thus becoming impractical as the problem scales. To address this issue, this paper proposes a solution that makes use of machine learning techniques for...
According to the problem of the rising sub-health people and the potential undetectable chronic diseases, this paper researches and develops a kind of portable ECG health monitoring system, which can make real-time acquisition about ECG information in the high degree of portable, reduce the patients' psychological pressure with not to be restricted on the use scene, and implement a daily ECG healthy...
Automated parking system (APS) is a mechanical system designed to minimize the area and/or volume required for parking cars. It is a solution for areas with a minimum place to parking, especially in city center. Sometimes there are some APS which are equipped with charge station for E-vehicle. Respecting power consumption of APS and possible charging stations there should be a problem with supply...
In this research, an intelligent lithium-ion battery-charging management system is proposed. The system integrates the battery monitoring and balance platform (BMBP) and charging station. According to the battery information of BMBP and the user needs, a proposed dual charging method (DCM) is used to control the charging voltage or current of charging station. The DCM contains the rapid and the smart...
The public has become more conscious of the importance of food quality and its effects on the human health. Consuming the expired food may lead to serious health problems, thus, a food freshness real-time monitoring system that is safe, inexpensive, and highly accurate is needed to ensure that customers can choose food packages with the best quality. In this paper, we demonstrate a method to monitor...
Environmental protection is one of the most challenging tasks for humanity. All of the latest technologies to certain extent are applied in this area, among others, wireless sensor networks as well. In this paper a wireless sensor node designed specifically for monitoring of environmental parameters is described. The main advantage of this node is the use of energy harvesting techniques and supercapacitor...
Trends in voltage battery charging of wireless sensor in monitoring network are discussed. They are obtained from experiments and interpolated by cubic splines. This makes it possible to get graphical representation of theoretical relation for voltage sensor battery charging versus time.
Implementation of precision apiculture methods into practice is highly depended on availability and cost-effectiveness of honey bee monitoring equipment. Expenses of monitoring system installation and maintenance activities also should be minimized. In order to successfully predict different bee colony states like: swarming, determine nectar collection activity and health of honey bees both in active...
The lifetime of a wireless sensor network (WSN) is limited by the lifetime of the individual sensor nodes. A promising technique to extend the lifetime of the nodes is wireless energy transfer. The WSN lifetime can also be extended by exploiting the redundancy in the nodes' deployment, which allows the implementation of duty-cycling mechanisms. In this paper, the joint problem of optimal sensor node...
The depletion of energy from petrochemicals has been a long time. Global energy supply and demand and environmental warming are facing serious challenges. At this stage development of new energy sources is to achieve the most efficient and reliable in the shortest possible time. Therefore, the development of renewable energy is national development priorities, including solar energy, wind energy,...
Cardiovascular (CVD) disease causes many people dying every year and these are sudden events hence can cause immediate death if not diagnosed early. Electrocardiogram (ECG) is the best available option today for diagnosis of heart and problems related to it. But conventional methods for ECG monitoring are based on line voltage so, it can contain noise and ECG signals are very sensitive to noise. It...
Power management is of prime concern when power generation and utilization is done using PV Cell. In the existing system, the PV Cell is normally connected in parallel with the Load or Grid. In such type of system the connected battery is charged while load run using the Cell. This makes the battery to be charged with less amount of current hence it doesn't get fully charged properly. Moreover, even...
Our live work training system addresses the need for developing the professional skills of HVB maintenance operators; thus, an employee initially trained to be a live work operator can develop towards the status of live work coordinator. Each initial training course has its own advanced training module, which helps meet the requirements of RTE and reinforce the skills of employees. Our training method...
This paper details the implementation of a supervisory controller executing within the microcontroller of an embedded system. The plant, a dual-axis solar tracking system, is developed and modelled as a discrete event system. The events generated by the plant are monitored and controlled by the supervisor executing within the system's onboard microcontroller. An optimized, light weight Evaluation...
Distributed process execution is a scalable solution for implementing workflows that deal with many devices in the Internet of Things (IoT). In hierarchical network structures the execution of activities and subprocesses can be moved closer to the computing edge onto specialized devices while still preserving data security. However mobility, resource constraints and varying connectivity of devices...
Comparing with the traditional grid, energy internet will collect data widely and connect more broader. The analysis of electrical data use of Non-intrusive Load Monitoring (NILM) can infer user behavior privacy. Consideration both data security and availability is a problem must be addressed. Due to its rigid and provable privacy guarantee, Differential Privacy has proverbially reached and applied...
Safety-critical autonomous systems, like robots working in collaboration with humans, are about to be used in diverse environments such as industry but also public spaces or hospitals. Those systems evolve in complex and dynamic environments and are exposed to a wide variety of hazards. Several techniques may be used to ensure that their misbehavior cannot cause unacceptable damage or harm. One of...
The presented paper introduces a sensor minimal battery observer, which allows the equipping of each stack with only one voltage and one current sensor, without losing the required individual cell measurement. The individual cell measurement is required not only for many Li-Ion applications with cell chemistry that can result in exothermic reactions. For a stack with 12 cells this can results in a...
