(54) УСТРОЙСТВО ОПРЕДЕЛЕНИЯ СКОРОСТИ И НАПРАВЛЕНИЯ ВЕТРА НА СОРТИРОВОЧНЫХ(54) DEVICE FOR DETERMINING THE SPEED AND WIND DIRECTION ON SORTING
1one
Изобретение относитс к железнодорожному транспорту и может быть использовано в системах автоматического регулировани скорости скатывани отцепов на сортировочных горках дл определени сопротивлени движению отцепов от воздушной среды .The invention relates to railway transport and can be used in systems for automatically controlling the speed of unhooked rolls on the humps to determine the resistance to the movement of unhooks from the air environment.
Известно устройство дл определени скорости и направлени ветра на сортировочных горках, содержащее формирователь времени осреднени , фазовый дискриминатор , счетчик скорости ветра с генераторами импульсов, выход одного из которых соединен с фазовым дискриминатором, а другого - с фазовым дискриминатором и одним входом счетчика скорости ветра, другой вход которого подключен к формирователю времени осреднени , а выход - к вычислителю сопротивлени воздушной среды и предназначено дл работы с оператором 1.A device for determining the speed and direction of the wind on the humps, containing an averaging time generator, a phase discriminator, a wind speed counter with pulse generators, one output of which is connected to a phase discriminator and one of a wind speed counter, the other the input of which is connected to the averaging time driver, and the output to the air resistance calculator and is intended for work with the operator 1.
Однако устройство имеет короткую линию св зи между датчиком и измерительным пультом и подвержено вли нию помех.However, the device has a short link between the sensor and the measurement console and is subject to interference.
Цель изобретени - повышение помехоустойчивости устройства.The purpose of the invention is to improve the noise immunity of the device.
Поставленна цель достигаетс тем, что устройство снабжено блоком определени The goal is achieved by the fact that the device is equipped with a block definition

свободной длины пути, соединенным с формирователем времени осреднени , модул тором с генератором частоты и счетчиком импульсов направлени ветра, входы которого подключены к модул тору и формирователю времени осреднени , а выход - к вы числителю сопротивлени воздушной среды, при этом входы модул тора соединены с генератором частоты и фазовым дискриминатором .free path length connected to the averaging time generator, modulator with a frequency generator and a wind direction pulse counter, the inputs of which are connected to the modulator and averaging time generator, and the output to the air resistance calculator, while the modulator inputs are connected to the generator frequency and phase discriminator.
На чертеже приведена блок-схема ройства.The drawing shows the block diagram of the device.
Устройство содержит датчик 1 ветра, состо ший из импульсаторов опорной 2 и основной 3 серий, соединенных с дискриминатором 4, генератор частоты 5, счетчик 6 скорости и счетчик 7 направлени ветра, моду15 л тор 8, формирователь 9 времени осреднени , соединенный с блоком 10 определени свободной длины пути, и вычислитель 11 сопротивлени воздушной среды. Устройство работает на основании цик2Q лически повтор юш,ихс измерений средних значений скорости и направлени ветра. Длительность каждого цикла равна интервалу осреднени , величина которого определ етс временем движени отцепа по подгорочThe device contains a wind sensor 1 consisting of pulsators of the supporting 2 and main 3 series connected to the discriminator 4, a frequency generator 5, a speed counter 6 and a wind direction counter 7, a modulator 8, an averaging time generator 9 connected to the determination unit 10 free path length and air resistance calculator 11. The device operates on the basis of cyclically repeated repetition, measuring the average values of wind speed and direction. The duration of each cycle is equal to the averaging interval, the magnitude of which is determined by the time of movement of the uncoupling on the podgorocha
