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.
