Arm Embedded System

The audio and video decoding and synchronization playback system ofMPEG-2 TS stream is designed and implemented based on ARM embedded system. In this system, hardware processor is embedded in the ARM processor. In order to make full use of this resource, hardware MFC is adopted. The multi-format codec decoder decodes the video data and decodes the audio data using the open source Mad (libmad) library. The V4L2 (Video for Linux2) driver interface and the ALSA (advanced Linux sound architecture) library are used to implement the video. Because the video frame playback period and the hardware processing delay are inconsistent, the system has a time difference between the audio and video data operations, which causes the audio and video playback to be out of sync. Therefore, we use the method of synchronizing the video playback implemented to the audio playback stream; realize the audio and video are playing sync. Test results show that, the designed audio decodes and synchronization playback system can decode and synchronize audio and video data.

In order to adapt to the requirements of intelligent video monitoring system, this paper presents an ARM-Linux based video monitoring system for face detection. In this system, an ARM processor with a Linux operating system was used, and the USB camera was used to capture data, and then the face detection was conducted in the ARM device. The OpenCV library was transplanted to Linux embedded system. The algorithm of face detection was realized by calling the OpenCV library. Specially, adaboost algorithm was chose as the face detection algorithm. Experimental results show that the face detection effect of the system is satisfactory and can meet the real time requirement of video surveillance.

Leakage Monitoring

Liquefied Petroleum Gas (LPG) is used in many ranges of applications like home and industrial appliances, in vehicles and as a propellant and refrigerator. However, leakage of LPG produces hazardous and toxic impact on human begins and other living creatures. There by, the authors developed a system to monitor the LPG gas leakage and make alert to users of it. In this research, MQ-6 gas sensor is used for sensing the level of gas concentration of a closed volume; and to monitor the consequences of environmental changes an IoT platform has been introduced. Robust control along with cloud based manual control has been applied so that the gas leakage can be prevented in the response of either feedback or feedforward commands individually. It switches on the specified relays to control the level of gas concentration in the time of leakage the excess gas in times of leakage. It rechecks the value again and again if it crosses 300 ppm it will setup a relay-based switching on control mechanism using Thingspeak cloud. The controller used here is Node-MCU v:1.0. This research provides design approach on both software and hardware. Hence an embedded system comprising of Relay switches, Embedded C++, Gas sensor, Temperature & Humidity sensor along with Internet of Things (IoT) is fabricated to meet the objectives of the current research.

Detection And Recognition

This article proposes the design of a novel hardware embedded system used for automatic real-time road sign recognition. The algorithm used was implemented in two main steps. The first step, which detects the road signs, is performed by the maximally stable extremal region method on HSV color space. The second step enables the recognition of the detected signs by using the oriented fast and rotated brief features method. The novelty of the embedded hardware system, on an ARM processor, leads to a real-time implementation of the ADAS applications. The proposed system was tested on the Belgium Traffic Sign Detection and Recognition Benchmark and on the German Traffic Signs Datasets. The proposed approach attained a high detection and recognition rate with real-world situations. The achieved results are acceptable when compared to state-of-the-art systems.

<span>Safety system such as smoke detector and fire alarm are considered to be a counter measure for fire accident. This safety system is important as it acts as a security measure against fire accident which could lead to death and destruction of properties. This paper propose an advanced gas leakage, fire and power supply failure monitoring system with Arduino UNO and GSM Module as its embedded system. Among the features of this system are their ability to detect the presence of smoke, gases and power failure at homes and factories, then the system will send a text message using Short Message Service (SMS) to the registered mobile number via GSM Module informing the user the situation and location of the incident. As a result, the user or person in charge can respond to the emergency situation accordingly and alert the fire departments or relevant authorities in time. This system could help the user to transform the way they protect their property and critical infrastructure. Successful safety and security transformation requires a combination of end user structural and operational changes as well as technology evolution enablement. This is in line with the Fourth Industrial Revolution (known as IR4.0), that propose substantial increase in the deployment of sensors for collecting, processing, and communicating measurement data in real time in order to diverse working environments, thus, resulting in advancement and convergence of technologies.</span>
