(54) DEVICE FOR XRTROL SWITCHING TRANSFER

FROM THE LOCOMOTIVE 36 friends and those equipped with short switchwork are isopulated: w sections, since the generated information about the state of the object can be received by the locomotive semi-assembly of the device and, therefore, will be lost. This disadvantage eliminates the possibility of using known devices in conditions of small distances between controlled objects (arrows), equipped with short arrow-isolated areas, which reduces the area of application. The aim of the invention is to expand the scope of use. The aim is achieved in that an element is inserted into the device. And, the OR element and the second element are NOT, and the output of the control decoder is connected to the inputs of the OR element, the output of which is NOT connected through the second element to the first input of the AND element, the second input of which is connected to the output of the first element NOT, and the output is connected to the second input of the clock generator . The invention is illustrated in the drawing, which shows the block diagram of the device. The device contains a trigger 1, amplifier 2, elements ° NOT 3 and 4, element 5, clock generator 6, distributor 7, diode array 8, delay element 9, memory block 10, indicator 11, encoder 12, transmit-receive unit 13, control decoder 14, execution unit 15, element OR 16. When transmitting control information to transfer the arrow from the locomotive, the receiving and transmitting unit 13 receives these signals, converts them and feeds them to the control decoder 14 At one of the outputs of the decoder 14, signal 1 corresponding to the transfer arrow in one of two positions. All outputs of the decoder 14 are connected to the executive unit 15 and the element OR 16. The executive unit 15 controls the switch. translation in accordance with the command received from the decoder. Upon completion of the transfer, in the execution unit 15, a signal containing the primary information about the state of the object (the arrow) is raised. The role of the primary information sensor is performed by the contacts of the signaling relay, which is located in the executive unit and is included in the object control circuit. This primary information in the form of single DC signals comes from the executive unit 15 to the memory unit 10. After the signal from the block 15 is received, the trigger 1 and one of the cells of the block 10 are shifted to the state. Through the amplifier 2 and the element is NOT 3, this signal from the output of unit 1 is fed to the input of element AND 5. In the event that the ordering signal continues to flow to the input of the transmitting and receiving O 13, and, consequently, the decoder 14, at the output of the element OR 16, there will be a signal I, and at the output of the element is NOT 4 the signal O. Thus, at one input of the element 5 there will be the signal I, and at the other input there will be the signal O. Therefore, the output of block 5 will also contain the signal O and the clock generator 6 will be locked. After termination of the spreading signal, all the outputs of the decoder 14 will have the signal O, and therefore, the output of the element is HE 4 -. Signal 1, thus on input: element AND 5 There is also a signal that leads to the appearance of a signal at the output of block 5. This opens tacts 1st oscillator 6, which controls the distributor 7. A five-bit is used as a distributor counter with a decoder in the form of a diode matrix 8. After the start of the clock generator, the information is read from block 10. The information from block 1O is read as follows. Block 1O consists of memory triggers, each trigger being connected to a specific output bus of the matrix by a shoulder on which signal 1 appears when the state of the object changes. The output busbars of the diode array 8 are run sequentially by the signals of the distributor 7, which is controlled by the clock generator 6. Short pulses. signals 1 are sequentially transferred from one bus to another. If signal 1 from block 10 and signal I coming from distributor 7 coincide, then a signal appears at the corresponding output of matrix 8, and the clock generator 6 and distributor 56 step 7 are braked and delay element 9 is triggered. The delay element 9 operates in a timed mode, i.e. some time after the start, a reset signal is given to the block 1O from the output of the element of the holder. Prior to the appearance of a reset signal at the corresponding output of the diode matrix 8, there is a signal 1, which feeds into the encoder 12, where it is converted into a code that triggers the transmitter of block 13, and the transmission of the directive information occurs. The time during which the signal i exists at the output of matrix 8, on determines the duration of the transmission of information information, and depends on the selected parameters of the time specifying the delay element 9. After the occurrence of a reset signal at the output of block 9, memory block 10 returns to its initial state, signal 1 from the output of matrix 8 is removed, and clock generator 6 is released and distributor 7 starts bypassing

the following tires block 8.

After the signal from the distributor 7 arrives at the last, the so-called reset bus, and the total reset signal is completed, the entire device returns to its original state.

To the first control output of the diode array 8, the indicator 11 of the state of the 1-way bus of the diode array 1 is connected. The indicator 11 is a transistor switch, in the collector circuit of which the bulb is turned on Initial state.

In the initial state, there is a signal on the control needle and the light is on. If a signal I appears on the signal bus, the signal O will be on the control bus and the light will go out.
