GSM based remote control for distributed systems

摘要

In this paper are presented the results regarding the implementation and testing of a novel type of remote control based on the data transmission facilities offered by the GSM network infrastructure and the processing power achieved by new generation of microcontrollers. The system is intended to be used in the development of complex distributed control applications that are specific to various automated industrial processes, including the manufacturing of printed circuit boards and electronic modules. The proposed control system was designed using a prototype board equipped with Atmega 328 microcontroller. For implementation of data communication between the remote modules that compose the distributed control system a Quectel M10 quad-band GSM/GPRS radio modem was used. The quality of the proposed design was evaluated through extended performances analysis focused on the delay time, maximum transfer rate, failure tolerance and reliability. The system allows versatile configuration of command's structure and can operate with an extended set of commands for the remote modules. Also, compared with other implementation solutions the proposed design can be used almost in any location due to the large availability of the GSM infrastructure.
