10 port GSM relay switch with GUI
Bartulec, Tomasz ; Lattenberg, Ivo (referee) ; Janovič, Filip (advisor)
System hardware and software design for a GSM switch with ten switching outputs, controlled via SMS. Description of used GSM module and its properties, feasibility and requirements, design and description of supply circuits for module outputs to relay outputs decoding, plug-in realisation of outputs. GSM module application software creation, remote SMS control requests implementation, sender's phone number check and information about completed requests by call-backs. Adding AT command to set up device. Development of web server providing control of switch throught Internet browser, solving communication between server and device, and data management. Testing of created SW and evaluation of final design from aspects of usage.

Position monitoring with the help of GPS/GSM modem
Zavadil, Miloš ; Vyoral, Josef (referee) ; Šilhavý, Pavel (advisor)
The first chapter of bachelor thesis is focused on theoretical explanation of the most important terms in Global Positioning System describing basic principles and position monitoring possibilities. The structure of the whole GPS system and its position setting accuracy is described further. The NMEA protocol used for transferring GPS information is shortly mentioned too. The second chapter deals with Open AT platform used for application development. It is a product of Wavecom company. The third thematic unit has already practical character. It shows the results of locating GenLoc25 modem by AT commands and decoding NMEA frame. Three variants of applications developed in Microsoft Visual C++ are described in the last chapter. All of them are used for position monitoring with GPS/GSM modem. The first program has the same functionality as the modem locating by AT commands. It is only for visualization of GPS information in Terminal window. The second application we can consider as the most important in this thesis. It contains all the items from the assignment. Actual data position is automatically sent to FTP server by GPRS transmission. The data are stored on this server. Received data are visualized in web browser by PHP script which is stored on server too. Final application is derived from the second one. The algorithm assumes that data are not sent to server regularly but transmission depends on human factor.
