Peristaltic pump control via USB interface
Balogh, Jaroslav ; Chmelař, Milan (referee) ; Čech, Petr (advisor)
The purpose of this bachelor’s thesis is to practical realization of connection between peristaltic pump Rainin Dynamax RP-1 and PC, using USB interface. Integrated circuit device FT232R has been used in USB-RS422 converter, due to modified RS422 interface, which the pump RP-1 uses. There was also developed software for pump’s remote controll. RP-1’s functions can be driven from remote side or eventually automatized with this software. This work is based on semestral thesis and in future can be used in another aplications with RS422 or with RP-1 pump. Department of Biomedical Engineering, attached to FEEC, Brno University of Technology, will use this remote controll in analysis of DNA.

Peristaltic Pump Controll Unit
Charvát, Jakub ; Kopečný, Lukáš (referee) ; Ligocki, Adam (advisor)
The work deals with the problematic of peristaltic pumps and it collects theoretical background information of this topic. The primary goal of the work is the implementation of peristaltic pump and the implementation of protection against equipment damage by overpressure. The overpressure evaluation system in this thesiss on the principle of current measurement of the motor pump. In this work, this premise is successfully tested and applied to the device. Another goal of this work is to create a desktop application that will monitor and control the pump. he data between the application and the device were successfully transfered by the MQTT communication protocol. The communication between the computer and the pump has been tested successfully.

Automatic Dosing Unit for Pool Chemistry
Kejík, Jan ; Štůsek, Martin (referee) ; Zeman, Kryštof (advisor)
The objective of this thesis was to design and construct the dosing unit for pool chemistry with the features of common available equipments, but with lower acquisition costs compared to these equipments. The initial part of this thesis describes the requirements for water quality in the pools and the principles of its sustaining. The next section describes the ESP32 microcontroller, which was selected because of sufficient computation power and memory resources and RF connectivity capability. Furthermore, the pH, ORP probes and temperature sensors for measurement of the pool water quality are described in this section. Lastly, sensor convertors, power supplies, pump controls circuit and display interface are described here. The key section of the thesis is the design description which consists of hardware, mechanical and software section. It starts by the description of the printed circuit board with a description of diagram. In the section followed is described and illustrated mechanical design of the box for this dosing equipment. It is my own design made by 3D print. The last design section deals with software consisting of three different kinds of software: display software, ESP32 microcontroller firmware written in C/C++ and HTML code of the webside. This description is focused especially on the firmware architecture of the processor ESP32 related to consecutive part including description of a local user interface as well as a web application. The resulting device was developed to the state with matured well tested user interfaces. However, the controls algorithms of pH and ORP were tested only in simulated conditions. Therefore the testing in real pool for verification of the firmware and reliability should be done in the next steps.
