Koncepcja, projekt i wykonanie systemu automatyki budynkowej wykorzystującego sieci Internet i GSM

摘要

System automatyki budynkowej wykorzystujący sieci Internet i GSM zaprojektowano i wykonano w ramach pracy magisterskiej. Głównym założeniem projektu była realizacja postawionego zadania jako rozszerzenie możliwości popularnego urządzenia sieciowego - routera TP-Link WR1043nd. W celu zdalnej komunikacji i sterowania urządzeniami podłączonymi do systemu, wykorzystano sieci Internet i GSM. W ramach pracy napisano oprogramowanie umożliwiające sterowanie urządzeniami podłączonymi do systemu i bazujące na systemie OpenWrt.%Design and construction of a control system for the building automation system was the object of the study. In the project there were made remote communication and control devices connected to the system by the Internet and GSM networks. The main control unit of the control system is a typical network device TP-Link WR1043ND. The structure of the automation system is shown in Fig. 1. The operating software written in Bash [6] controls the automation system. Nominal TP-Link firmware was updated by OpenWRT Linux based firmware. The system was equipped with an operating panel in the form of a website (Fig. 3). The relay board was used to communicate with actuators and sensors applied in the system. The presented system also enables communication with 1-Wire sensors by use of the converter. The system was integrated with a weather station WS10180 as well. The system devices can be controlled in real time by the operator panel or SMS commands. Additionally, the system enables the running of devices according to the established schedules (Fig. 5). The measurement data of weather conditions can be used to control building automation. The completed software allows connection a USB camera and realization of mini-monitoring with the detection function and motion acquisition in the form of images. The project uses the soundcard-which enables the function alerts and information about events in the system. By using a router as a central unit, the automation system will be more versatile and can be used in most households, and other buildings. An additional advantage of the system is the low cost and easy availability to purchase components necessary for its implementation.
