In our fast-paced world, there is an ever increasing demand for remote control and automatization in electronics. Devices are often installed to places which are hard or costly to access. Therefore, a solution is needed which provides access without requiring any physical intervention. The variety of devices that are aimed to ensure the management and control of a system from remote observation points is broadening constantly. Due to their many applications, these solutions are very popular in industry and everyday use. In the automatization and security industry, Ethernet technology has one of the largest number of cost-effective designs that provide relatively quick communication and are not limited by physical distance.
The subject of my study is to design a circuit diagram of a device that can connect to an Ethernet network, while establishing automated peripheral control with its GPIO interface. The final product will be an appartus mounted in an outdoor watertight box that can be set up and handled easily by the installer and is able to respond to binary output devices by running two state systems. The completed circuit can be manufactured and utilized in itself, while it has the potential for further development with much more complex functionality.
Before drawing the schematic, I have mapped the tools available on the market, and by adopting their properties, I systematized the functions of the designed module according to the optimal implementation of the task. In the following sections I will describe the designing method and the operation of the integrated circuits and other components used. I begin the designing steps by presenting the block diagram of the instrument then separately present the operation of the other circuits.
