Abstract
Настоящее изобретение относится к средствам специальной связи, предназначенным для передачи программ аналогового и цифрового телевидения, а также информационных сообщений по каналам радиосвязи. Предлагаемая микроволновая телерадиоинформационная система содержит подсистему приема и обработки информационных сообщений, центральную станцию и абонентские терминалы. Центральная станция содержит многоканальный сверхвысокочастотный передатчик, передающую антенну и линию связи между передатчиком и антенной. Сверхвысокочастотный передатчик содержит частотный модулятор, умножитель частоты с лавинно-пролетным диодом, выходное устройство и фильтр в каждом канале передатчика, а также устройство для синхронизации работы каналов передатчика. Предлагаемая система содержит, дополнительно, устройство для формирования сигналов, передаваемых по каналу цифровой связи, ретрансляторы и радиорелейные станции. Центральная станция содержит, дополнительно, кодирующее устройство и компьютер с программным обеспечением, обеспечивающий контроль оплаты услуг связи и защиту от неразрешенного доступа к системе. Абонентский терминал содержит приемно-передающую или приемную антенну, приемник или приемопередатчик и устройство связи с абонентом. Преимущества предлагаемой системы: увеличение дальности связи, уменьшение неблагоприятного влияния технических средств на окружающую среду, возможность дуплексной связи, повышение надежности и уменьшение стоимости оборудования за счет использования серийных элементов, повышение степени унификации элементов оборудования, возможность модульного исполнения системы, уменьшение периода времени для подготовки системы к работе и периода времени для прекращения работы системы, возможность сопряжения системы с существующими кабельными и волоконнооптическими системами телефонной связи, а также с информационной сетью "Интернет", повышение пропускной способности при передаче информационных сообщений в системе, повышение уровня помехозащищенности при передаче сигналов, уменьшение мощности излучаемых радиосигналов, уменьшение потребляемой электрической мощности.
