Within the framework of this work, a software that allows simple control over the energy consumption of lighting devices in a simple and fairly cheap way without the use of special expensive sensors and other reading equipment has been created. With the help of this software we can perform the following works:
start and configure the camera connected to the computer;
determine in a unit of time the state of illumination or switching off of lighting devices;
set the amount of electricity consumption per unit of time;
installation and removal of virtual sensors.
The software, using the TTimer component, places frames received from the web camera in the TImage component in the form of Bitmap every second, then the array of pixels (points) is analyzed for the presence of bright dots corresponding to the lighting state on the frames. The analysis is done by splitting the color using the color model RGB (Red - Red), Green - Green, Blue - Blue) to the corresponding colors. Thus, the program can determine whether lighting works or doesn’t, the duration of its operation.
Having established in the program the amount of electricity consumed per unit of time, without the use of special devices and devices, a program was created to determine the energy consumption of lighting devices.
The program was developed on Delphi object-oriented programming language.
Operation systems: Windows XP, Windows Vista (32x, 64x), Windows Seven (32x, 64x), Windows 8 (32x, 64x), Windows 10.
