Designing a Brushed DC Motor Driver with a Novel Adaptive Learning Algorithm for the Automotive Industry

In this study, a stepper driver, which is suitable for use in the automotive industry, designed for general use, capable of adaptive learning in the systems in which it is used, and with CAN and universal asynchronous receiver–transmitter (UART) communication options, was designed. This design was made with a PIC18F25K22 microcontroller unit (MCU). Rotor speed, armature current, and terminal voltage can be measured on the proposed brushed DC motor drive system. It gives the desired response by evaluating obstacles and other situations in which high currents are drawn from the source. The speed measurement of the vehicle and the open and closed status of an automatic door can be monitored. The main contribution of the designed PCB is an adaptive learning algorithm (ALA) that uses the pulses of the encoder, estimates the position of the step, and manages the operation process to prevent mechanical damage at the final point of the motor. Furthermore, unexpected hitting and pinching which are defined as obstacles to the driver can be controlled by monitoring the current value drawn from the driver. The benefit of this method is that the life of the mechanical step is increased due to the management of the forward and backward step operation, preventing potential accidents.

The role of technology in modern industrial processes: a comparative analysis of automated, automatic and mechanical systems

In the modern technological sphere, systems are categorized into various types based on their level of complexity and functional capabilities. The primary types are mechanical, automatic, and automated systems. Each of these types has its unique characteristics and areas of application. Mechanical systems are the simplest of all. They consist primarily of physical components such as gears, levers, and springs, which interact to perform specific tasks. These systems typically lack built-in control or regulation mechanisms, and their operation is based on basic mechanical principles. Examples of mechanical systems include simple clock mechanisms or traditional measuring devices. Automatic systems represent an evolutionary step beyond mechanical systems, as they include elements for automatic control. These may be electrical or electronic components that enable the system to perform certain operations without direct human intervention. For example, automatic doors or thermostats that regulate room temperature are examples of such systems. They can respond to changing conditions and perform tasks based on predefined parameters. Automated systems, in turn, are the most complex and integrated. They combine automatic control with software and advanced management systems, allowing them to adapt to changing environmental conditions and make decisions independently. Automated systems may include elements of artificial intelligence and machine learning, enabling them to perform complex tasks such as data processing or optimizing production processes. Examples include industrial robotic lines or management systems in distribution networks. Thus, the main differences between these systems lie in their level of complexity and functional capabilities: mechanical systems are based on simple physical principles, automatic systems contain elements of automatic control, and automated systems provide a high level of integration and autonomy.

A novel air curtain: Multi-parallel ejector air curtain for blood plasma cold storage

The installation of air curtains above the cold storage doors can reduce energy consumption. However, with the advancement of the refrigeration industry, the functions of cold storage have become more diversified and intelligent, rendering conventional fan-driven air curtains inadequate to meet market demands. Previous studies on air curtains primarily focused on their operational parameters and structures, neglecting the compatibility and applicability of air curtains with the functions of cold storage, thus lacking comprehensive experimental evaluation methods for their suitability. This study proposes a novel multi-parallel ejector air curtain suitable for automated plasma cold storage equipped with automatic doors. The performance of the air curtain is obtained through a comparison with conventional fan-driven air curtains in terms of sealing efficiency, temperature change and humidity change. Experimental results demonstrate that when the discharge velocity is 14 m/s, the multi-parallel ejector air curtain achieves a sealing efficiency of 39.6 %, resulting in a decrease of 0.92 ℃ in the average temperature rise within the cold storage and a reduction of 5.98 % in relative humidity increase. The sealing efficiency of conventional air curtains is 11.38 %, leading to a decrease of 0.82 °C in the average temperature rise within the cold storage and a reduction of 3.08 % in relative humidity increase. Analysis indicates that for automated plasma cold storage, the multi-parallel ejector air curtain is more applicable than conventional air curtains. At discharge velocity of 21 m/s and 26 m/s, the sealing efficiencies of the multi-parallel ejector air curtain are 54.47 % and 56.43 %, respectively, suggesting that moderately increasing the discharge velocity of air curtains contributes to enhancing their performance.

Avoiding ‘bungalow legs’: active ageing and the built environment

ABSTRACT Urban populations across the globe are ageing and much debate has centred on what constitutes an ‘age-friendly’ city. Historic environments, for example, often present physical challenges, such as steps and uneven surfaces – while today these are designed out. Smooth level surfaces, automatic doors and elevators to change level, require little exertion. However, has the fact that in order to keep our bodies healthy into older age, a level of physical exertion in our day to day lives is required, been overlooked? Can activity be designed back into environments without undoing the benefits of accessibility and causing harm to others?

An Automatic Sliding Door: Leveraging Locally Sourced Materials for Innovation

A door is an essential component of a building. It provides security and access to the different parts of a building. In the modern era, when people want everyday life to be completely automated so that work can be done easily in a short amount of time without wasting energy, automatic doors have continued to be fashionable. In addition to being effective and efficient as automation continues to develop rapidly, automatic doors are essential to curbing the transmission of infectious diseases like Ebola and COVID-19. While automatic doors are available in Nigeria, they are imported, thereby shrinking the nation’s foreign exchange. Not only that, but they also cost more when imported compared to when they are manufactured locally. In this work, therefore, a cost-effective automatic sliding door was developed using locally sourced materials from Nigeria. The door uses a passive infrared sensor (PIR) to detect a human or an object in a doorway and automatically opens and closes the door by signalling a microcontroller to activate a DC motor, which drives a belt pulley mechanism. The conceptual design of the system was designed and simulated using SolidWorks. Based on the design, calculations were made to determine the appropriate materials to source. The DC motor model was simulated using MATLAB SIMULINK as a physical model to observe how it would behave in the presence of noise, and the PID controller was tuned to give optimal performance using MATLAB Auto tuning. Some materials were locally purchased, while others were constructed through standard workshop methods. A cost-saving advantage of 95.77% and 89.13% were achieved when compared to imported equivalent types from the USA and China, respectively. The siding door was assembled and subjected to a functionality test, and it was observed that the automatic sliding door successfully detects humans and objects and actuates the motor to open and close the door after the object is out of the set sensing range of 50cm. This work is a step forward in boosting local innovation in Nigeria.
