ВВЕДЕНИЕ
Одним из основных видов средств связи являются радиорелейные линии
прямой видимости, которые используются для передачи сигналов
многоканальных телефонных сообщений, радиовещания и телевидения,
телеграфных и фототелеграфных сигналов, передача газетных полос. Все
виды сообщений передаются по РРЛ на большие расстояния с высоким
качеством и большой надежностью.
В начале 70-х годов на магистральных РРЛ были внедрены новые
радиорелейные системы “Восход” и “Дружба”, рассчитанные уже на передачу
1920 ТФ каналов в одном стволе, а также сигналов черно-белого или
цветного телевидения совместно с сигналами четырех каналов звукового
сопровождения.
1. ВЫБОР ТРАССЫ. ОПРЕДЕЛЕНИЕ СТРУКТУРЫ ПРОЕКТИРУЕМОЙ РРЛ
1.1 Требования, предъявляемые при выборе трассы РРЛ
Обеспечение связью населенных пунктов с учетом перспективы их развития.
Обеспечение высокого и стабильного по уровню и по времени принимаемого
сигнала. Надежность и качество связи должна удовлетворять нормам.
Релейные станции располагаются зигзагообразно во избежание
интерференционных замираний.
Необходимо обеспечить удобство электроснабжения, подъездные пути,
возможность реализации продукции связи.
Радиорелейные станции по возможности располагаются на естественных
возвышенностях с целью снижения высоты подвеса антенн.
Радиорелейные станции по возможности располагаются вдали от аэродромов.
Запрещается использование плодородных пахотных земель.
1.2 Определение типа РРЛ
Тип РРЛ определяется исходя из протяженности трассы, а так же исходя из
скорости передачи цифровых сигналов. Протяженность проектируемой трассы
составляет 100 км., а скорость передачи 2,048 Мбит/с. Следовательно
данная линия является линией местной связи.
1.3 Составим структуру проектируемой РРЛ
Определим количество участков проектируемой РРЛ
Участком называется расстояние между двумя узловыми станциями или между
оконечной и ближайшей узловой, а в случае если участок один, то между
оконечными.

результаты расчета занесем в таблицу 1
По данным расчета строим профиль интервала.
Для этого выберем масштаб и строим ЛУНУ.
По горизонтали в 1 см=2 км.
По вертикали в 1 см=10м.
Расстояние h+y откладываем в соответствии с теми же координатами Ki, а
затем соединяем полученные точки ломаной линией.
Профиль интервала построен.
2.2 Определение высот подвеса антенн.
Определяем относительную координату наивысшей точки профиля интервала по
формуле (6):

Статистика показывает, что примерно 50% рабочего времени, работа
происходит не в условиях свободного пространства, а в условиях
положительной рефракции, т.е. распространение радиоволн происходит с
небольшим огибанием земной поверхности, поэтому реальный просвет
становится больше чем в свободном пространстве, и такой интервал
называют открытым, а увеличение просвета характеризует приращение
просвета ДН(q).
Определим приращение просвета ДН(q) при положительной рефракции
характерной для 50% рабочего времени, по формуле (8):

Слишком большой просвет быть не должен т.к.
1) Возрастает опасность интерференционных замираний, когда в точку
приема приходит основной сигнал и отражается от земли или тропосферы в
противофазе с основным.
2) Недостатком большого просвета является удорожание антенных опор и
необходимости сигнального освещения мачт и дополнительные потери в
фидерах.
Рекомендуемый просвет Н, м. выбираем в пределах, по формуле (9):

Определим высоту подвеса антенны по чертежу профиля интервала
От наивысшей точки профиля интервала вертикально вверх откладываем
полученную величину Н. Через полученную точку проводим прямую линию так
чтоб высоты подвеса антенн были примерно одинаковыми.
Определим относительный просвет интервала P(q), по формуле (10):

2.3 Определение устойчивости связи
Для расчета устойчивости связи необходимо рассчитать минимально
допустимый множитель ослабления.
Множитель ослабления зависит от параметров аппаратуры и от коэффициента
ослабления антенно-волноводного тракта (АВТ).
Определим потери в АВТ по формуле (11):

где аЭЛ = 3 дБ – потери в сосредоточенных элементах
аn = 0,05 дБ/м – погонное затухание
LВЕР 0 – длинна вертикального фидера. LВЕР = 0 так как приемное и
передающее оборудование совмещено с антенной.
LГОР – длинна горизонтального фидера. Выбираем LГОР = 0,5 м для каждой
станции.

Определим параметры сферы для оценки влияния экранирующего действия
препятствия.
Для этого от наивысшей точки профиля интервала вертикально вниз
откладываем расстояние, равное просвету свободного пространства H0.
Через полученную точку проводим линию параллельную прямой соединяющей
антенны до пересечения с профилем интервала.
Определим ширину препятствия r, км.
r = 11,5 км
Определим относительную величину препятствия L, км., по формуле (15):

-47,55дБ = 20lgx
x = 0,0042
Т.к. подкоренное выражение отрицательно и равно – 0.26, значит, срыва
связи из-за интерференционных замираний не будет.
2.5 Расчет величины Tд(Vmin)
Величина Tд(Vmin) учитывается на ЦРРЛ работающих на частотах выше 8 ГГц.
По известному значению Vmin определяем максимально-допустимую
интенсивность дождей для данного пролета.
J = 200 мм/год
По графику в зависимости от номера климатического района определяем Tд
от Vmin. Tд = 0,0001%, т.к. район Урала сухопутный район.
Расчет допустимого времени срывов связи для всей линии.

ВЫВОДЫ ПО ПРОДЕЛАННОЙ РАБОТЕ
Расчетное время срывов связи равно 2,73*10-8% и значительно меньше, чем
допустимое время срывов связи, которое равно 0,01 %, следовательно,
срывов связи не будет.
