Description

Изобретение относится к железнодорожной автоматике и-телемеханике, в частности, к устройствам передачи кодов автоматической локомотивной с сигнализации (АЛС) в горловинах стан- ^эций.The invention relates to a rail-telemechanics automation and in particular to devices for automatic transmission locomotive with signaling codes (ALS) in the neck stan- ^e tions.

Известно устройство для передачи непрерывных сигналов AJiC в зоне стрелочной секции, содержащее эле«трические рельсовые цепи, образованные дву- ¹⁰мя рельсовыми нитями, к которым подключены передатчики сигналов АЛС [1 ].A device is known for transmitting continuous AJiC signals in the area of an arrow section, containing electric rail circuits formed by two ¹⁰ rail threads to which ALS signal transmitters are connected [1].

Недостаток такого устройства — возможность ложного восприятия кодового сигнала подвижной единицей, на 15 соседней рельсовой цепи, при нарушении изоляций изолирующих стыков, так как кодовый сигнал подается параллельно во все ответвления, а не строго по заданному маршруту. Это снижает безопасность движения.The disadvantage of this device is the possibility of a false perception of a code signal by a mobile unit on a 15 neighboring rail circuit, if the insulation of the insulating joints is violated, since the code signal is supplied in parallel to all branches, and not strictly along a given route. This reduces traffic safety.

Известно также устройство для кодирования разветвленной рельсовой цепи, содержащее установленные на пути передатчик кодов и коммутатор, выхо- *5 да которого через проводные линии соединены с рельсами ответвлений [2].A device for coding a branched rail chain is also known, which comprises codes transmitter and a switch installed on the path, the output of which * 5 is connected via branch lines to branch rails [2].

Однако это устройство нельзя ис-’ пользовать для передачи информации на поездные и маневровые локомотивы при 30 электрической тяге, так как на работу приемных устройств АЛС оказывают| большое влияние гармоники тягового тока.However, this device cannot be used to transmit information to train and shunting locomotives with 30 electric traction, since the operation of ALS receivers is | great influence of harmonic current traction.

Цель изобретения - расширение функ· циональных возможностей.The purpose of the invention is the expansion of functional capabilities.

Для этого в устройстве передачи кодов автоматической локомотивной сигнализации для разветвлённых рельсовых цепей второй выход передатчика кодов автоматической локомотивной сигнализации подключен к общему для обоих ответвлений рельсу.,For this, in the device for transmitting automatic locomotive signaling codes for branched rail circuits, the second output of the automatic locomotive signaling code transmitter is connected to a rail common to both branches.,

На чертеже представлена структурная электрическая схема устройства.The drawing shows a structural electrical diagram of the device.

Устройство содержит передатчик 1 кодов автоматической локомотивной сигнализации, первый выход 2 которого связан с коммутатором 3. Выходы коммутатора 3 через проводные линии 4 и 5 соединены с ответвлениями рельса 6. Другой выход 7 передатчика соединен с общим для обоих ответвлений рельсам 6.The device comprises a transmitter 1 for automatic locomotive signaling codes, the first output 2 of which is connected to the switch 3. The outputs of the switch 3 are connected to the branches of the rail 6 via wire lines 4 and 5. Another output 7 of the transmitter is connected to the rails 6 common to both branches.

Устройство работает следующим об'разом. _ ' 'При задании маршрута движений иа путевой участок кодовый сигнал АЛС с выхода 7 передатчика поступает в общий для обоих ответвлений рельс 6/The device works as follows. _ '' When setting the route of movements of the route, the ALS code signal from the output of the 7 transmitter enters the rail 6 common to both branches

850467 .850,467.

затем через проводные линии 4 или 5, проложенные по подошвам вторых рельсовой коммутатор 3 возвращается на выход 2 передатчика 1.then through the wire lines 4 or 5, laid on the soles of the second rail switch 3 returns to the output 2 of the transmitter 1.

Проводные линии 4 и 5 через коммутатор подключаются₄к выходу 2 перееатчика 1 в зависимости от положения трелки и направления движения.Wire lines 4 and 5 are connected through a switch ₄ to the output 2 of the transmitter 1, depending on the position of the skid and the direction of movement.

Ток кодового сигнала АЛС, проходя по указанной цепи, наводит в приемных катушках подвижного состава сигнал, который расшифровывается.локомотивными приборами(существующих систем автоматической локомотивной сигнализации .The current of the ALS code signal, passing along the indicated circuit, induces a signal in the receiving coils of the rolling stock, which is decrypted by locomotive devices (existing automatic locomotive signaling systems.

toto

Величина кодового сигнала во всей зоне съема информации в пределах стрелочного перевода практически постоянна и не зависит от места нахождения локомотива, а шунтирующее действие колесных пар; находящихся на стрелочной секции, не оказывает каких-либо влияний на кодовый сигнал АЛС. В результате информация на подвижной единице может быть принята в любой точке трассы маршрута и не зависит от направления движения и наличия багонов сзади и спереди локомотива.The value of the code signal in the entire area of information retrieval within the turnout is almost constant and does not depend on the location of the locomotive, and the shunting action of the wheelsets; located on the arrow section, does not have any effect on the ALS code signal. As a result, information on a mobile unit can be received at any point on the route of the route and does not depend on the direction of movement and the presence of bagons at the back and front of the locomotive.
