Abstract:
At usages object armses important place is conducted questions of the monitoring the condition of the control systems and object, as well as work installed on them equipments, for operative checking the production processes and automations of the experiment, finding the deflection of the control values, measurements been rejected (deviate) parameter. Presence of the large number of the sources to information, directed to united processing centre, proves need of the distribution and checking information flow, enterring from sensor of the registrations parameter signal in telemetry system (TMS). The Organized analysis existing measuring military systems have shown need of the development TMS, taking into account conditions controlled object before damage, miscellaneous priority channel of the different purpose, are characterized by high speed of the testing and possibility of the current checking the condition of the object and his (its) systems on distance. In the course of analysis of the process of the removing to measuring information on controlled object is offered approach to decision given problems by presentation of the first subsystem TMS, as systems of mass service (SMO) with refusal, where controllers present itself channels of the service. Designed mathematical model many-server TMS as SMO one channel with limited by queue allows to define the optimum number a channel relationship (KS) between subsystem of the collection to measuring information, located near technological object, and point of the checking and distribution with provision for inconsistent requirements to fitness to checking, noise-immunity and send rate to measuring information. For decision of the problem of the calculation of the required number channel in many-server communication link and greater clarity result was used set graph in the manner of graph of the dependencies different parameter systems, as well as is calculated required amount used channel. The organized analysis quotient factors quality channel of the issue different type to information. The generalised factor is offered for decision of the problem of the many criterion of the shaping the many-server telemetry system by method of the consequent conces-sions, taking into account priority compacted channel. Also, practical realization of one of the subsystems under development TMS is offered in the manner of device of automatic searching for channel radio communication, realizing choice optimum KS and providing increase to validity of the choice of the optimum channel, to account two stages of the analysis.
