Forestry cableway remote diagnostics
Říha, Pavel ; Pazdera, Ivo (referee) ; Klíma, Bohumil (advisor)
This bachelor's thesis focuses on description of electronics and controllers of forestry cableways Larix. The stress is laid on controlling system among others working with GSM modem securing the communication with remote monitoring centre. The analysis of the need of local as well as remote diagnostics leads to definition of requirements for communication channel that needs to be secured. Applying GSM net and communicate through standardised industrial modems connected through port RS232 is suggested as the most effective solution. The main part of the dissertation includes particularities and possibilities of communication through GPRS service. All-embracing communication channel including the server that transfers data packets among particular clients is designed and programmed. The final part summarizes achieved results and outputs of testing compiled solution including data throughput and response. Simultaneously based on acquired experience some procedures for final implementation in evolution and production of new types of cableways are recommended.

Remote diagnostics of the combustion engine in real time
Jobánek, Vojtěch ; Beran, Martin (referee) ; Svída, David (advisor)
There is a current trend of constantly increasing emphasis on the cost-effective operation of vehicles in freight and passenger transportation. One of the efforts is to reduce the unproductive time of the driver and the vehicle which is spent on maintenance and repairs. The unproductive time can be significantly minimized by well-timed and faultless diagnostics that is, ideally, without need for a service visit. Real-time remote diagnostics, including an application that evaluates the current state of the vehicle, is a modern tool for efficient use of the vehicle.

Remote Lift Malfunction Diagnostics
Weisser, Filip ; Husák, Jiří (referee) ; Fučík, Jan (advisor)
The objective of this bachelor's thesis was to apprise with the elevator control unit and to design a conventer to communicate with a server. Next objective was to design a program to collect and store information sent by the elevator control unit and visualize it. This communication runs through the TCP/IP protocol and data are stored in a database and visualized through a web interface. Testing was done by a control unit, which partially replaces the elevator system.
