Description
секундомером и электронный секундомер 11.stopwatch and electronic stopwatch 11.
Измерение несинхронности торможени т гача и прицепа предлагаемым способом осуществл етс следующим образом .The measurement of the non-synchronization of the braking of the tractor and trailer by the proposed method is carried out as follows.
Начало торможени т гача фиксируетс тензометрическим акселерометром 1, преобразующим замедление объекта в электрическое напр жение. Это напр жение усиливаетс усилителем 3 и поступает на пороговое устройство 5 на выходе которого по вл етс скачок напр жени , как только напр жение Превысит заданный порог срабатывани . Скачок напр жени преобразуетс форирователем 7 в короткий импульс, небходимый дл управлени электронным секундомером П.The onset of braking is recorded by a strain gauge accelerometer 1, which converts the deceleration of the object into an electrical voltage. This voltage is amplified by amplifier 3 and fed to a threshold device 5 at the output of which a voltage jump appears as soon as the voltage exceeds a predetermined threshold. The voltage jump is converted by the forwarder 7 into a short pulse necessary to control the electronic stopwatch P.
Начало торможени прицепа опреел етс по сигналу тензометрического датчика 2 давлени , преобразующего давление рабочего агента в тормозной магистрали прицепа в электрическое напр же 1е. Усиленное усилителем 4 напр жение поступает на пороговое устройство 6, порог срабатывани которого выбираетс в зависимости от давлени , необходимого дл срабатывани тормозов прицепа . Скачок напр жени с выхода порогового устройства преобразуетс формирователем 8 в короткий импульс, поступающий на устройство 10 управлени секундомером.The start of trailer braking is determined by the signal of the strain gauge pressure sensor 2, which converts the pressure of the working agent in the brake line of the trailer into electrical voltage 1e. The voltage amplified by the amplifier 4 is fed to the threshold device 6, the response threshold of which is selected depending on the pressure required to operate the trailer brakes. The voltage jump from the output of the threshold device is converted by the shaper 8 into a short pulse arriving at the stopwatch control device 10.
Первым импульсом, пришедшим от акселерометра 1 или датчика 2 давлени , устройство 10 управлени включает электронный секундомер 11, а вторым выключает его, независимо от очередности прихода импульсов.The first pulse coming from the accelerometer 1 or the pressure sensor 2, the control device 10 turns on the electronic stopwatch 11, and the second turns it off, regardless of the order of arrival of the pulses.
Дл определени знака несинхрон йости торможени т гача и прицепа служит схема 9 распознавани очередности срабатывани , принцип действи которой основан на совпа цении во времени импульсов, приход щих с формирователей 7 и 8, с импульсами управлени секундомером.To determine the sign of non-synchronization of braking of the gauge and the trailer, use the pattern 9 for recognizing the sequence of operation, the principle of which is based on the coincidence in time of the pulses arriving from the formers 7 and 8 with the control pulses of the stopwatch.
Предлагаемый способ обеспечивает повышение точности при проверках и испытани х тормозных систем транспортного поезда.The proposed method provides improved accuracy during inspections and tests of brake systems of a transport train.
