Abstract

1. Способ исключения задержки передачи сообщений при устранении конфликтов доступа, характеризующийся тем, что используют источники сообщений, посылающие приемнику сообщений и возвращаемые приемником оптические сигналы по отдельному для каждого источника беспроводному каналу на двух частотах, причем сигналы первой частоты импульсные, используемые для передачи сообщений от источника к приемнику, сигналы второй частоты постоянные, посылаемые приемнику источниками и возвращаемые источникам с прерыванием на время получения приемником сигнала первой частоты от всех источников с наложением во времени, при этом источник, обнаружив наложение сигналов, переходит к устранению конфликта доступа, являющегося причиной наложения сигналов первой частоты.2. Система исключения задержки передачи сообщений при устранении конфликтов доступа, характеризующаяся тем, что содержит в приемнике сообщений фотоприемник посылаемых источником сообщений оптических сигналов первой частоты, выход которого подключен к усилителю электрических сигналов, выход которого соединен с модулятором оптических сигналов второй частоты, расположенным между источником сообщений и ретрорефлектором, возвращающим источнику сообщений получаемые от него оптические сигналы первой и второй частот, содержит в источнике сообщений передатчики оптических сигналов первой и второй частот, направляющие эти сигналы в ретрорефлектор приемника, и фотоприемники возвращаемых ретрорефлектором приемника сообщений сигналов первой и второй частот источника сообщений.1. A method of eliminating the delay in transmitting messages when resolving access conflicts, characterized in that they use message sources that send a message receiver and optical signals returned by the receiver through a separate wireless channel for each source at two frequencies, the first frequency pulsed signals used to transmit messages from source to the receiver, the second frequency signals are constant, sent to the receiver by the sources and returned to the sources with interruption at the time of receipt by the receiver a signal of the first frequency from all sources with an overlay in time, while the source, having detected an overlap of signals, proceeds to eliminate the access conflict that causes the superposition of signals of the first frequency. 2. A system for eliminating message transmission delays when resolving access conflicts, characterized in that it contains a photodetector in the message receiver of the optical signal source of the first frequency, the output of which is connected to an electric signal amplifier, the output of which is connected to a second frequency optical signal modulator, located between the message source and a retroreflector, which returns to the message source the optical signals of the first and second frequencies received from it, contains in the source with The transmitters of the optical signals of the first and second frequencies directing these signals to the retroreflector of the receiver and the photodetectors of the messages of the first and second frequencies of the message source returned by the retroreflector of the receiver are messages.
