For a wide range of applications in industry, it is sometimes necessary to perform acoustic source localization. In this paper, a passive sound localization and classification system is designed and implemented. Each sensor consists of a microphone array which is used to detect the direction-of-arrival (DoA) of an acoustic signal. Multiple DoA sensors can be combined to form a wireless sensor network...
Wireless localization has been the focus of research due to the wide range of applications it can enable, particularly in industrial hazardous areas where warning systems are crucial for safety. Although there are a number of different technologies available for indoor localization such as Wi-Fi and ultra-wideband, Bluetooth based localization is usually less expensive to deploy and all smartphones...
Localization is important for a wide range of industries and applications. In underground mining, for instance, it is helpful to know the miners' locations, particularly in emergency situations. One way this can be achieved is by using ultrasonic based localization. This paper presents the design and implementation of a wireless sensor network which can be deployed in underground mines to perform...
Fish conservation is a concern due to the impact of industrial fishing that causes overfishing. Fish farming has been an approach to fish conservation and systems are required to monitor ecosystems. This paper describes the design of a solar powered autonomous fish pond management system that can be used for fish conservation. The system consists of a floating node, equipped with sensors, that is...
In this paper, an indoor office locator system is developed. The product developed uses body sensors to detect incoming objects using indoor positioning tracking algorithm which run on a server application to guide the user in an office environment were designed and developed. It is shown that overall the final system allowed a partially blind user to navigate the office with relative safety and accuracy.
Many vehicle accidents are caused by driver fatigue. Systems to monitor driver fatigue can contribute to a decrease in fatalities. This paper describes the development of a multi-sensor system for driver fatigue detection. The system achieves this by monitoring eye closure and wheel steering movements, and is able to alert the driver of any detected anomalies. Various techniques are suggested for...
Biometric systems are important for access control and authentication in various application scenarios. Single biometrics can be selected for authentication, but a multimodal approach is typically more reliable. In this paper, a multimodal biometric authentication system is developed. It consists of wireless sensor nodes equipped with accelerometers and infrared cameras, which enable analysis of gait...
Hazardous environments at the workplace are a significant contributor to injuries due to accidents as well as chronic diseases. There are many occupational health and safety (OHS) systems, but they are costly or not flexible. This paper presents a low-cost OHS. It consists of various sensors that can be used to monitor whether a safety helmet is being worn, the worker is mobile and safety boots are...
In emergency situations such as fires in homes and offices, it is often the case where members of a response team (eg. firefighters) are not able to locate each other due to fire and smoke. It is desirable to have a system which is able to locate all personnel such that a team leader can monitor their location and to enable the firefighters themselves to know their proximity to other firefighters...
Electric shocks due to high voltage lines can pose serious health risks to workers. Reliable and efficient systems to alert workers of nearby live power lines are necessary. In this paper, a personal high voltage safety system with wear monitoring is designed and implemented. A wrist module which consists of an electric field detector and optical heart rate monitor is developed from first principles...
This work describes the development of a mobile incident response system which can be used by public entities such as the police or municipality services to improve the assignment of response teams to reported incidents. It is also shown that the system can be easily integrated to augment current indoor air quality monitoring systems in future buildings. The system is based on the capability of smartphones...
This paper describes the work carried out on the implementation of a wireless sensor network that was created for a data center using the 6LoWPAN communication protocol which monitors power consumption readings at various nodes in the system. A direct current (DC) network controller was designed to distribute DC energy through the system and provide power to a data center load in future buildings...
With the world progressively heading towards an energy crisis, renewable energy sources and technologies have become the focus of research. Harvesting the sun's energy through solar thermal power plants (STPPs) is an attractive alternative to the use of energy supplied through the grid. However, installation and maintenance of cabling for communication and control of a heliostat array for STPPs is...
A wireless sensor node platform was created along with a base station that can be used to monitor various parameters in the industry. A literature survey was conducted on important parameters found in the industry. The various standards that are set out for these parameters were analysed. The developed wireless sensor node platform along with the base station shows that a wide variety of industrial...
Water is a vital component in our daily lives, and a precious resource to human race. This paper describes the work carried out on the design of a water management system that can log pressure and pH readings wirelessly and determine if there is a water leak within the pipe system or if the pH levels of the water are safe enough for human consumption. A pipe monitoring system was designed, implemented...
Impulse radio ultra-wideband (IR-UWB) ranging and localization have recently received significant attention due to the high accuracy and precision. This high accuracy can be exploited for many location aware applications in a wide variety of environments. Although most research efforts have focused on location-aware applications for indoor or outdoor environments, there are other environments, such...
