Description

tt

Изобретение относитс к системам промышленной автоматики и может быть использовано дл управлени перемещением объектов.The invention relates to industrial automation systems and can be used to control the movement of objects.

Известно устройство дл дистанционного управлени , сбдержаицее три кнопки управлени , два управл ю щих реле, три сигнашъных лдмпы и транзистор til .A device for remote control is known, with three control buttons, two control relays, three signal plates and a til transistor.

Недостатком данного устройства вл етс отсутствие автоматического сн ти блокировки после выполнени команды.The disadvantage of this device is the lack of automatic unlocking after executing the command.

Наиболее близким по технической сущности к предлагаемому вл етс устройство, содержащее подключенные к шинам питани параллельно соединенные цепи/ кажда из которых содержит последовательно соединенные элемент управлени , размыкающий контакт отклон ющего элемента и коммутационный элемент, входы отключающих элементов подключены соответственно к замыкающим контактам коммутационных элементов и через первые замыкающие контакты отключающих элементов к первой шине питани , а выходы - через фиксирующий элемент к второй шине питани 2 .The closest in technical essence to the present invention is a device comprising parallel-connected circuits connected to the power buses / each of which contains a control element connected in series, an opening contact of the diverting element and a switching element, the inputs of the disconnecting elements are connected respectively to the closing contacts of the switching elements and through the first closing contacts of the disconnecting elements to the first power bus, and the outputs through the locking element to the second power bus 2

Недостатком данного устройства вл етс мала надежность.The disadvantage of this device is low reliability.

Цель изобретени - повышение наг дежности устройства.The purpose of the invention is to increase the reliability of the device.

Эта цель достигаетс тем, что в устройство введен блок блокировки, вход которого подключен через параллельно соединенные замыкающие конл такты отключающих элементов к первой шине питани , котора соединена через размыкающие контакты блока блокировки с соответствующими зa ыкaющими контактами коммутационных элементов , а выход блока блокировки под5 ключей к выходам отключающих элемен . тов.This goal is achieved by introducing a block into the device, the input of which is connected via parallel-connected closing contacts of the disconnecting elements to the first power bus, which is connected through the opening contacts of the blocking block to the corresponding closing contacts of the switching elements, and exits disconnecting elements.

Claims

The drawing shows a functional diagram of a device for controlling an object. 0 The device contains control elements (1, 1, l, ... 1) (buttons), switching elements (contactors 2, 2, 2, ... 2 with contactors 3, 3, 3, ... 3, disconnecting elements 4 , 4 4, .., 4 with break contacts 5, 5, 5, ... 5 first closed contacts 6, 6, 6, ... b and the second contacts 7, 7, 7, ... 7, block 0 8 interlocks with break contacts 9, 9, 9, ... 9, fixing element limit switch 10 and first 11 and second 12 power lines. The device works as follows. In the initial state, the end switch 10 is open, the contactors 2,. . . 2, disconnecting elements 4, ... 4 and block 8 block de-energized. When you press one of the control buttons, for example, 1, the shutter 2 activates and starts moving: the object in the corresponding direction. The closing contact of the Z.contactor 2, closing, prepares the switching off element 4 for switching on. The movement of an object in a given direction is stopped when it acts on the limit switch 10. At the same time, element 4 is energized by disconnecting and opening its opening trip I OHtouch 3 / de-energizes the contactor 2. At the same time, the first closing contact f of the tripping element ters the circuit from the series-connected 3s of the pin 5 of the contactor 2 and the 7 contacts of the block 8 of the lock and the circuit that stores the final state of the object. The closure of the second closing contact 9 of the tripping element 4 both bakes the power supply of the block B blocking. Disconnection contacts 7, ... 7 last time, by blocking the operation of the tripping elements 4, ... 4 until the limit switch 10L is opened. In this state, it is possible to start moving the object in any direction except the direction corresponding to the control button 1. When ngokatii, for example, button 1 triggers contactor 2 and begins moving the object in the corresponding direction. In this case, the limit switch 1 is opened, de-energizing the disconnecting elements 4,.,. block 8 blocking. In view of this, the interlocking of the contactor 2 is released. Further work is carried out as described above. The use of the invention improves the reliability of the device. The invention The device for controlling an object contains parallel-connected circuits connected to the power buses, each of which contains a control element connected in series, an opening contact of the tripping element and a switching element, the inputs of the tripping elements are connected respectively to the closing contacts of the switching elements and through the first closing contacts of the disconnecting elements to the first power rail, and the outputs through the locking element j the second power rail, owing to the fact that o, in order to increase the reliability of the device, it contains a blocking device, the input of which is connected via parallel-connected closing contacts of disconnecting elements to the first power bus, which is connected through the opening contacts of the blocking block to the corresponding closing contacts of switching elements, and the output of the blocking device is connected to the outputs disconnecting items.
