Embedded System Using Field Programmable Gate Array (FPGA) myRIO and LabVIEW Programming to Obtain Data Patern Emission of Car Engine Combustion Categories

Abstract

Engine scanner unit is a tool used by mechanical power to know the condition of car engine combustion at the time of tune up process done.The level of elements and compounds that dominant in determining categories of combustion of gasoline fuel car engines through the levels of elements and compounds contained in exhaust emissions are Hydrocarbons (HC), Carbon Monoxide (CO), Carbon Dioxide (CO2) and Oxygen (O2). Complete combustion category produces maximum power, fuel efficiency and emission levels according to the threshold. This occurs when there is a balance of the amount of fuel, airflow and ignition in the engine combustion chamber. Elements and compounds contained in car exhaust emissions can be detected with sensors that are sensitive to elemental levels and these compounds are HC, CO, CO2, and O2 sensors. This study aims to display the data pattern category of combustion engine through exhaust emissions based on multi sensor detection processed with signal processing system in the form of Fast Fourier Transform (FFT) process. Furthermore, data pattern is performed in accordance with the category of combustion engine detected. The system is designed with embedded system using Field Programable Gate Array (FPGA) myRIO and LabVIEW programming. The results in the test displays the data pattern and the comparison test of the reference data pattern with the data pattern of the detection result. The comparison test result of data pattern similar to 87% complete engine combustion category and similar to incomplete combustion category 90%.

Monitoring dan Kontrol Gas CO Dalam Ruangan Berbasis Pemrograman LabVIEW dan Mikrokontroler

“…Mikrokontroler Arduino UNO digunakan sebagai interface dengan Personal Computer (PC) dalam hal ini Laptop. Sistem pengkondisi sinyal yang ada pada rangkaian sensor akan mendefinisikan besaran tegangan analog yang ketika adanya perubahan unsur dan senyawa gas CO [16]. Hasil tegangan analog diolah melalui program LabVIEW pada PC.…”

Sistem Kontrol Berbasis Pemrograman LabVIEW MyRIO untuk Monitoring Kualitas Udara Dalam Ruangan

“…Program LabVIEW dikenal juga dengan sebutan program berbasis Virtual instruments (VI) karena penampilan dan operasinya dapat menirukan sebuah instrument alat ukur atau display hasil pengujian agar memudahkan pengguna berinteraksi dengan sistem [18][19][20]. Pemrograman LabVIEW di upload menjadi sistem embedded menggunakan modul Field Programable Gate Array (FPGA) myRIO [21,22]. Untuk mendeteksi kadar gas yang ada dalam ruangan, pada penelitian ini menggunakan komponen sensor gas dengan kode MG 811 untuk CO2, dan kode MICS-6814 untuk gas CO. Sistem yang dirancang pada penelitian ini melakukan 2 fungsi yaitu melakukan pemantauan atau monitoring kualitas udara yang ada pada ruangan secara realtime dan mengontrol kualitas udara ruang jika kadar CO dan CO2 melebihi ambang batas yang ditentukan.…”

Optimization Audicor for Normal and Abnormal Heart Sounds Characteristic

“…S. Barma et al implement third heart sound (S3) detection based on non-linear signal decomposition and time-frequency localization [6]. Andrizal et al use FFT to detect the data pattern categories of the combustion engine based on exhaust emission [7]. This paper implements FFT and PCA for feature extraction on normal and abnormal heart sounds.…”

“…After that, the blood flows through the small size of the vascular vessel surrounding the air pockets in the lungs to absorb oxygen and release carbon dioxide, and then blood will flow back to the heart. On the left side of the heart, the oxygen-rich blood will transfer into the left atrium through the mitral valve, then the blood will be going to the throughout the body except lungs through aortic valve [7][8] [9]. In the pumping process of the blood throughout the body, the heart will produce the sound continuously that commonly known as lub and dub.…”
