Real-Time Wireless Control for a Data Acquisition-Based Micro-Computer System

Abstract

Real-time communications (RTC) wireless multi-channel data acquisition systems provide promising remote interactive solutions. This paper develops and implements wireless octet channels for data detection and processing. Data analysis and suitable control action are accomplished by using an Arduino UNO controller interfaced with the National Instruments (NI) LabVIEW virtual engineering toolset. A simple graphical user interface has been developed and implemented. Sensors for humidity, pulse, temperature and motion are used for reading the environmental parameters. The system can accommodate measurements of eight individual parameters at different reading speeds. In addition, high-accuracy data measurements can be obtained by using the mean values technique for the three sensors in cases such as temperature and humidity. An efficient storage technique for dated and timed data can be optimized to cancel all successive repeated measurements. Whenever the environmental parameters have been changed the system will store only the updated changes, thus providing an accurate enough description of the sensor output as well as significant reduction in required memory. Quad flags are implemented as the actuators triggering signals. The acquired data can be remotely monitored via either smartphones or computers located in the WI-FI local area network coverage area.
