Design of ZigBee device - Analog inputs in range 0 - 10 V
Vepřek, Jan ; Kacz, Peter (referee) ; Štohl, Radek (advisor)
This bachelor thesis deals with design and realization device with analog inputs for ZigBee module. The first part of thesis contains analyse of possible solutions design of device and selecting the best choice. In the second part is function and connection of real circuits which I have used in device. In the third part is introduced function of software and description of functions. The communication between microcontroller and circuits through the use of programmed function is described. The last part is attended to user manual. There are descriptions controls of device and radio communication between two devices.
Module of Digital Inputs with Modbus Communication
Nožka, Tomáš ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
Bachelor’s thesis deals with the basic specification of Modbus protocol and its use for communication between the remote digital inputs device module and device that uses information obtained from remote inputs. The thesis proposal is to further describe hardware and software for the module. Processor i8051 series provides the function of the whole procedure. Unit acts as a slave device. Communication with the remote device is done via serial interface (RS-485 and RS-232) using one of two modes of communication either Modbus RTU or Modbus ASCII. Primarily information on the status of digital inputs are being provided to the remote devices. The work also includes information about some professional modules of inputs and outputs communicating via Modbus protocol.
Communication between PLC and Mahr Millitron 1840
Rysnar, Jiří ; Bradáč, Zdeněk (referee) ; Štohl, Radek (advisor)
Content of the Bachelor's thesis is to familiarise with Mahr Millitron 1840 measuring device and to create a programme using Step7 Microwin programming environment. Creating a programme for communication between Mahr Millitron 1840 measuring device, PLC S7-200 and TD100C display. Application of communication protocol MahrTalk. In parts of my thesis I first engage in description of constituent elements. Then in description of the functions of programme block and finally in describing the ladder diagram itself. Model of measuring device and setting and reading of parameters are read during the communication between the automaton and measuring device.
Function block for Simatic and Sinamics devices applied in speed applications
Vacek, Jakub ; Pásek, Jan (referee) ; Štohl, Radek (advisor)
This document contains basic information about the frequency converter SINAMICS S120, modular PLC S7-300 and SIMATIC STEP 7. The function block Standard telegram 9 and a set of functions (Move Absolute, Relative Move, Move Velocity, Jog) written in SIMATIC STEP 7, which is used to control the frequency converter communicating with PLC are also part of this document.
Model of the lift including AS-Interface network
Žůrek, Martin ; Hynčica, Ondřej (referee) ; Štohl, Radek (advisor)
This bachelor´s thesis occupies with a suggestion of the model of a lift which is driven by a serial industrial bus AS-Interface. In the introduction there is presented theoretical knowledge useful for the reader to the problems especially of the origin and fundamental parametrs of bus AS-Interface, description three levels referential model ISO/OSI which are included in AS-Interface. Further there is the description of transmission of analogical values and standard profiles which are used. In the other part I am trying to solve the model of the lift from the construction standpoint and function of component parts which are included in the lift model. The fourth part devotes to the communications protocol for the control of storeys and the cab box which are shown the data transmission between unit master and unit slave and the opposite. In the last part it is shown programming environment and routines and functions and connection unit slave to unit master. Enclosed are electrotechnical schemes of the model of the lift, the block of programme structure for PLC and technical docummentation of components.
ASI-I modul for lift control boxes
Cseri, Peter ; Fiedler, Petr (referee) ; Štohl, Radek (advisor)
In the first part of my thesis, I was studying materials about AS-Interface network. Then I designed connections between ASI chips and microcontroller that controls the elevator’s control panels. After that I designed all that on double layer board using Eagle layout editor 4.12r2. After that I completed the boards with all electronics circuits and electric components. Then I had to program microcontrollers and microchips for use. These control panels and programs are my final products of this project.
Module of Digital Outputs with Modbus Communication
Vaško, Pavel ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
Goal of mine bachelor’s thesis is create functional module of digital outputs, which can be seen in typical industry using. This module must contain communication interface on protocol Modbus and standard communication bus RS-232, RS-485. The module must be equipped with microcontroller series x51. Size of equipment must be minimalized into the smallest proportion. One part of the thesis is focused on theoretic information about Modbus protocol. Next parts contain charakteristics of communication and software facility.
Control of Curalon cycle batcher
Jílek, Tomáš ; Hynčica, Ondřej (referee) ; Štohl, Radek (advisor)
The work deals with the controlling design of batching machine polyvinyl alcohol fibre, its integration into existing production technologies and the real implementation and verification of the machine functionality for which a design has been made. It also includes a design and implementation operator panel through which can be possible for production line supervising staff to set parameters and monitor the process. Firstly, there is described the default process of dosage, required conditions and restrictions for the newly established dosing machine. In the following part features of newly designed batcher are described, further it deals with the basic parameters and characteristics of selected components, which are important for the execution of its own proceedings. The next part of the work is concerned in detail with the implemented function of controlling algorithm and operator panel, which is provided through interaction with the staff supervising the production line. The last chapter provides the basic configured parameters of the controlled components.
Hand-held terminal for HV tester
Coufal, Miroslav ; Macho, Tomáš (referee) ; Štohl, Radek (advisor)
The aim of this thesis is to design and manufacture of handheld terminal for high-voltage probe Spark 2030UL. There is described the design and manufacture of printed circuit boards of handheld terminal. There is described the creation of software for hand-held terminal too. In conclusion, this work is described and evaluated verification of the functionality of handheld terminal for high-voltage probe.
Automation Measurement System
Žampach, Aleš ; Havránek, Zdeněk (referee) ; Štohl, Radek (advisor)
Bachelor’s thesis is bent on creation control software for multimeter and function generator. The first part of the thesis is focused on theoretical problems of individual parts of the whole measuring system and his parts. It show communication control unit with measuring instruments over the GPIB interface. Second part serves to presentation to problems graphical programming method and either as manual to control software for automated measuring system. At last third part are introduced examples of validation measure for check functionality software.
