Design of multi-channel analog acquisition system based on DSP + FPGA architecture

This paper proposes a design and implementation of a general multi-channel analog acquisition system based on DSP + FPGA architecture. In terms of hardware architecture, FPGA is used to achieve high-speed and high reliability switching between different analog channels; FPGA + DSP data processing architecture is used to separate data acquisition and algorithm processing.

RANCANG BANGUN DESAIN INTERNET OF THINGS UNTUK PEMANTAUAN KUALITAS UDARA PADA STUDI KASUS POLUSI UDARA

Build, design and develop an Internet of Things design to monitor air quality in thewild with air pollution case studies. By utilizing the ESP-8266 type wifi modulemicrocontroller as the control center for the devices built by adding an IC4051 AnalogMultiplexer as a branching process from 1 analog channel to 7 analog channels. There are5 sensors used, namely CO (MQ-7), CO2 (Analog Infrared CO2), Dust Sensors (PM10),DHT-11 (Temperature & Humidity) and Wind speed & direction. Data recording locationand data monitoring using third party protocol, namely Ubidots.The research was conducted in 2 different locations with the time determined, namelyin the area of the UPR Informatics Engineering Department area and also in the village ofTanjung Taruna, Jabiren Raya District, Pulang Pisau Regency along with the Team of theKopernik Bali Foundation.The results of the study will be analyzed using the AQI (Air Quality Index) standardwhich is also the same as that of the BMKG as an air quality index index. By using realtimeinternet of things technology, it can make it easy to get information about the level of airquality in the wild quickly, efficiently, and the monitoring process can be done anywhereand anytime.

Integration of Power System Real-Time Digital Simulator and Optimal Power Flow

In this paper, a framework for integrating a real-time digital simulator and EMS-OPF program is proposed and addressed, through two different communication architectures: asynchronous and synchronous. Validation of these communication architectures is carried out by Ethernet UDP/IP (asynchronous) and analog channels of IO card (synchronous). With this framework, both dynamic and steady-state performance of a power system can be studied easily in real-time mode.

Implementation of Intelligent Video Analysis System and it’s Algorithm Optimization Based on DSP

This paper aims to implement an distributed intelligent video analysis system based on TI multimedia Digital Signal Processor (DSP) TMS320DM642, at the same time, the algorithm optimization is also described. The intelligent video analysis system we proposed provides users with fast and precise video analysis services. The video image is transmitted to the image processing board by analog channels and IP cameras, then the DSP processing the video flow. In this system, target detection, segmentation, feature extraction, alarm and automatic tracking can be implemented. In this system, several optimization techniques are also used in algorithms, including the algorithm level optimization (ALO), the program level optimization (PLO) and the instruction level optimization (ILO). Experimental results show the exellent result in reducing the CPU load.
