Description

Изобретение относитс к устройствам железнодорожной автоматики, в частности к устройствам контрол за работой систем автоматического управлени движением поездов,.The invention relates to railway automatics devices, in particular to devices controlling the operation of automatic train control systems.

По основному авг.св. №409914 известно устройство, которое содержит регистратор тока локомотивной сигнализации, включающий в се б генератор частоты, соединенный с индуктором и ycтaнoвлeнн зIe у первой колесной па- ю ры подвижного состава, приемные катушки, соединенные с формирователем импульсов, и с триггером регистрации, пифровой вольтметр , установленные у второй колесной пары , логический элемент И и блок печати, J5 вход которого подключен через логический элемент И к выходу триггера регистрации и цифрового вольтметра.By the main Aug.St. No. 409914, a device is known which contains a locomotive signaling current recorder, including a frequency generator connected to an inductor and stationary ground at the first wheel set of the rolling stock, receiving coils connected to a pulse driver, and a registration trigger trigger python voltmeter installed at the second wheel pair, the logical element And and the print unit, J5 input of which is connected through the logical element And to the output of the registration trigger and digital voltmeter.

Недостатком известного устройства вл ет с низка надежнос-ь действи при кратко- 20 временной потере шунта подвижной единицы.A disadvantage of the known device is a low reliability with short-term loss of the shunt of the mobile unit.

Цель изобретени - повьпиение надежности функционировани устройства.The purpose of the invention is to increase the reliability of the device.

Это достигаетс тем, что регистратор тока локомотивной сигнализации снабжен 25This is achieved in that the locomotive signaling current recorder is equipped with 25

элементом задержки времени и дополнитель ным логическим элементом И, одним входом подключенным к выходу элемента задержки времени, а другим - к выходу формировател импульсов, к которому подключен вход элемента задержки времени, причем выход дополнительного логического элемента И подключен к триггеру регистрации.a time delay element and an additional AND logic element, one input connected to the output of the time delay element, and the other to the pulse shaper output to which the input of the time delay element is connected, with the output of the additional AND logic element connected to the registration trigger.

На чертеже представлена блок -схема регистратора тока локомотивной сигнализации . Он содержит генератор 1 частоты соединенный с индуктором 2, установленным у первой колесной пары 3 подвижной единицы , рельсы 4 и 5 рельсовой цепи. У второй колесной пары 6 подвижной единицы установлены приемные катушки 7, соеддаенные с формирователем 8 импульсов, выход которого подключен к дополнительному логическому элементу И 9 непосредственно и через элемент 1О задержки времени.The drawing shows the block diagram of the recorder current locomotive alarm. It contains a frequency generator 1 connected to an inductor 2 installed at the first wheel pair 3 of the mobile unit, rails 4 and 5 of the track circuit. The second wheel set 6 of the mobile unit is equipped with receiving coils 7 connected to the driver of 8 pulses, the output of which is connected to the additional logical element I 9 directly and through the element 1O of the time delay.

Claims

The output of the element And 9 is connected via trigger-11 registration to the logical element And 12. Digital voltmeter 13 yo, dklkchen through the element And 12 to the block 14 of the print. The current recorder works as follows. Inductor 2, suspended from the first cart of the compartment unit (car) and receiving power from generator 1, creates a closed loop B consisting of wheel sets 3 and 6 and rails 4 and 5, alternating current. This current induces an emf in the receiving coil 7 suspended v of another trolley of the mobile unit. When driving through an insulating joint or when a wheel-rail contact is lost, the current circuit is broken and the EMF in coil 7 decreases sharply. At this moment, the pulse shaper 8, consisting of a Schmitt trigger and a trigger, produces a square pulse, the duration of which (Tf) is determined by the absence of EMF J & receiving coils. As an element of time delay 10, an oddowashing device having a pulse width T0 where iy is the base unit pressure (the distance between the wheelsets 3 and 6 V is maximum i allowed the speed of movement of the mobile unit in the given area. If the pulse duration T, the former 8 is longer the pulse duration Td of the time delay element Yu, then at the moment of the end of the pulse the delay time element opens the additional logic element 9 and triggers the registration trigger 11. If the pulse duration T is less above the pulse duration Tp, the logical element I 9 does not open "registration trigger 11 does not work. Thus, the device distinguishes the fact of passage of the isolating butt h short-term false shunt loss by the mobile unit, which increases the locomotive signaling current detector. Formula invented ff Current recorder locomotive signalization according to aut. St. 49999, characterized in that in order to ensure the reliability of operation, it is equipped with a time delay element and an additional logical element With the I input, one input connected to the output of the time delay element, and the other to the output of the pulse shaper, to which the input of the time delay element is connected, the Output of the additional logic device AND connected to the registration trigger.
