Cellular Modem Emulator for Accelerating the Development of Embedded Devices
Sechra, Marek ; Šimek, Václav (referee) ; Vašíček, Zdeněk (advisor)
The task of this work is to acquaint readers with the diversity of the market and the support of individual modems for AT commands. Get acquainted with other networks and related protocols and introduce readers to the issue of AT commands. Design and implement a modem emulator that will be easily extensible. The run of the emulator is recorded in the terminal console. The emulator is implemented in Python.
HW platform for surveillance over maritime container transport
Roško, Tomáš ; Možný, Radek (referee) ; Musil, Petr (advisor)
The complexity of international transportation is increasing, and with that, the logistics requirements also increase: such as the need to monitor containers’ location or measure inside conditions. Despite these demands, marine transportation faces specific technical problems, such as the need for sending data precisely, often, and with low energy consumption. This paper aims to create a monitoring device that meets the demands of marine transportation. The device combines satellite and mobile networks to control the container location and, at the same time, allows for precise pinpointing of place and availability of access while having low battery consumption. The theoretical part of the paper explains the process of selecting components and justification of the process with regard to market options. The practical part contains a diagram of the connection of the modules and sensors. Next, the design and manufacture of the printed circuit board and custom 3D printed box are discussed. The software part deals with data protocol and the description of the application, which is then tested with a particular focus on measuring and transmitting the values onto the server.
