Automatic people counting
Szalbot, Michal ; Mišurec, Jiří (referee) ; Koutný, Martin (advisor)
The main subject of this bachelor thesis is utilization of optical sensors for people vehicle counting. This types of sensors were selected - optical barrier, passive infrared sensor, active reflective sensor and ultrasonic sensor for people vehicle counting. The tasks and used sensors are described in introduction. The selected applications available on the market and description of their function are described there too. The solution describes individual type of sensors, their function, used involvement in tests and tests results. The conclusion contains summary of knowledge of sensors, their possibilities and other possible solutions.

Energy meter with PLC communication
Szalbot, Michal ; Mlýnek, Petr (referee) ; Koutný, Martin (advisor)
Our thesis is about development of equipment, which combine two technology. First technology is wattmeter which is used to energy measurement and second is Power line communication. Wattmeter needs two variables for measurement, voltage and current. Voltage measurement is less difficult than measurement of current. Voltage can be reduce and measured by A/D converter. Current has to be transform to voltage and than can be measured same way. To do that we use current transformer. Than we design program for the microcontroller, involvement and PCB. Wattmeter is connect to PLC modem which has been chosen. Fusing this two technology we create wattmeter network. Next step was program which is used to network control and data collecting. This data are used to create charts in web application.
