Resumo

We propose a method decentralized executed synchronous initiation of actions of a group of physical objects participants of a controlled experiment. Here, the objects detect the occurrence of events, which require joint actions of all objects, and without the participation of the control center create a common command to initiate the actions of the objects simultaneously or with additional delays prescribed for each object. For this purpose, objects exchange messages via a signal repeater that does not contain computational means, form a common command in it, and perform auxiliary calculations. Necessary for these actions the simultaneous arrival in the repeater messages objects with the alignment of their binary digits of the same name is provided. In general, in the method, a group of objects functions as a distributed control system, which corrects the execution of the experiment with minimum delays in response to the appearance of unforeseen or expected at unknown points in time events.
