Description
(54) УСТРОЙСТВО ДЛЯ ЛОКАЛИЗАЩШ УЧАСТКА(54) DEVICE FOR LOCALIZED LAND
ВОЗНИКНОВЕНИЯ ПЕРЕРЫВОВ В КАНАЛАХ СВЯЗИRELATIONSHIPS IN COMMUNICATION CHANNELS
II
Изобретение относитс к электросв зи и может использоватьс на магистрал х дальней св зи с целью локализации участка возникновени перерывов св зи в групповых и линейных трактах.The invention relates to telecommunications and can be used on long-distance trunk lines in order to localize the site of occurrence of communication interruptions in group and linear paths.
Известно устройство дл локализации участка возникновени перерывов в каналах св зи, содержащее на диспетчерском пункте последовательно соеди- . ненные приемник контрольной частоты и Q индикатор и на каждом контролируемом .пункте приемник контрольной частоты и ивдикатор, другой вход которого объединен со входом приемника контрольной частоты последующего контролируемого ,5 пункта DJA device for localizing the site of occurrence of interruptions in communication channels is known, which contains in series a connection at the control room. Control receiver frequency and Q indicator and on each controllable item a receiver of the control frequency and indicator, the other input of which is combined with the input of the receiver of the control frequency of the next controlled, 5 DJ points
Однако известное устройство допускает возникновение ошибок в определе-. НИИ номера поврежденного участка из-за разброса порогов срабатывани jg компараторов при наличии деетабилизиРУЮ1ЦНХ факторов.However, the known device allows the occurrence of errors in the definition. The scientific research institute of the number of the damaged area due to the scatter of the thresholds of triggering jg of the comparators in the presence of de-stabilized factors.
Целью изобретени вл етс повьппение точности локализации.The aim of the invention is to improve localization accuracy.
