In the system, the speed sensor alarm channels and time delay elements are adjustable.

The transmission control handle 4 is kinematically connected with the servomechanism 6, and the speed control handle 5 is connected with the servomechanism 7.

The servo mechanism 6 is equipped with cams 8, 9 and 10 and limit switches 11, 12 and 13 of its fixed positions interacting with them, respectively.

- 16.2 - the engine runs at a speed at which gear shifting to position XX is not permitted (in this case, signals 16.1 and 16.2 are present simultaneously).

The system contains remote controls:

The inputs of the controls on the OPU and VPU are connected to the power source through the switch 18, and the outputs of the controls on the OPU and VPU are connected in parallel according to their purpose.

The outputs of the command reversing control bodies are connected to control pairs of pairwise connected AND elements and memory elements according to the number of fixed positions of the servomechanism 6:

The output of the memory element 33 is connected via OR 39 and OR 37 via the command channel 37.1 to the converter 38 and simultaneously through OR 39 and OR 40 by the command channel 40.1 to the converter 41. Simultaneous switching of the converters 38 and 41 puts the servomechanism 6 and the associated motor handle to position 4 (Xx).

The output of the memory element 35 is connected via OR 40 command channel 40.1 to the Converter 41, translating the servomechanism 6 and the associated motor handle to position 4.1 (B).

The output AND 42 is connected to the recording input of the memory element 44, the output of which through OR 45 is connected to the converter 46, to its control 46.1 to increase the fuel supply to the engine (B) and through OR 47 to the converter 48 connected to the hydraulic control channel of the servomechanism 7 in parallel with an inductor 49 integrated in this channel. If there is no control signal on the converter 48, it is closed and the working fluid passes through the throttle 49. When a signal arrives at the converter 48, it is open and the working fluid passes through the converter 48 in addition to the throttle 49.

To other inputs And 43 connected signaling channels 11.1 and 16.1. The output AND 43 is connected via OR 45 to the control 46.1 of the Converter 46.

- 19.2 and 25.2 - to the input of the And 50 element and through OR 51 to the And 52 input.

To another inverse input And 52 is connected to the signaling channel 15.1. The output AND 52 through OR 53 is connected to the control 46.2 (M) of the Converter 46 to reduce the fuel supply to the engine.

The signal channels 12.1 and 15.1 are also connected to the inputs And 50, and the output And 50 is connected to the recording input of the memory element 54. The output of the element 54 via OR 53 is connected to the control 46.2 of the converter 46, and the signal channel 16.1 is connected to the reset input of the element 54.

The outputs of the command bodies 23 and 29 to control the rapid reduction of the engine speed to the position of the engine handle 5 “stop reversing” are connected via OR 55 to the inputs OR 47 and OR 51, then to the converter 48 and through the memory element 52 and OR 53 to the converter 46, to his governing body 46.2.

Command bodies 20 and 26 (H) are also connected to the engine quick reversing unit 56, to the input elements And 57 and 58 of the block.

Element And 57 is included in the channel for forming a fast reverse of a running engine when the servo mechanism 7 is in the “stop reverse” position or at a speed before the signal 16.2 occurs (when gear shifting to XX is allowed).

To the other inputs of the AND 57 element are connected:

- to direct inputs signal channels 11.1 and 16.1;

- to inverse inputs, signal channel 16.2 and command channels 33.1, 35.1 and 65.1. The output AND 57 is connected to the recording input of the memory element 59, to the reset input of which a signal channel 13.1 is connected. The output of the element 59 is connected by a channel 59.1 in parallel to the inputs of the elements And 60 and 61 and to the input of the element OR 55.

Signal channel 12.1 is connected to the second inverse input And 60 and to the second direct input And 61, signal channel 15.1 is connected to the third input And 61.

The output AND 60 is connected to the recording input of the memory element 62, the output command signal 62.1 of which is connected to the input OR 39. The signal channel 12.1 is connected to the reset input of the element 62.

Both 60 and element 62 form a gear shift control channel to position XX. The output AND 61 through the time delay element 63 is connected to the recording input of the memory element 64, the output command channel 64.1 of which is connected to OR 37. The signal channel 13.1 is connected to the reset input of the memory element 64.

And 61, the time delay element 63 and the memory element 64 form a transmission control channel to position N.

Element And 58 enters the channel for forming a fast reverse of a working engine when the servo mechanism is in any position above the “stop of reversal” at a speed that prohibits gear shifting to XX (there is a signal 16.2 of the engine speed sensor).

To other inputs And 58 connected signal channels 11.1 and 16.2.

The output And 58 is connected to the recording input of the memory element 65, to the reset input of which the signal channel 13.1 is connected

The output of the memory element 65 is connected by a channel 65.1 in parallel to the inputs of the elements And 66 and And 67 and to the input of the element OR 55. The signal channel 16.2 is connected to another inverse input And 66.

The output And 66 is connected to the recording input of the memory element 68, to the reset input of which the signal channel 12.1 is connected.

The output command channel 68.1 of the element 68 is connected to the input OR 39.

Element And 66 and memory element 68 form a channel for switching gears to position XX.

The output AND 67 through the time delay element 69 and the AND element 70 is connected to the recording input of the memory element 71, the output command signal 71.1 of which is connected to the input OR 37.

To other inputs And 70 connected signal channels 12.1 and 15.1. The signal input channel 13.1 is connected to the reset input of element 71. The element And 67, the element of the delay time 69, the element And 70 and the memory element 71 form a channel for controlling the gear shift to position N.

The system works as follows

For example, the engine is in the starting position when the speed control handle is in position 5 of the “reverse stop” at the local post, and the gear control handle is in position 4 (XX).

Depending on the position of the switch 18 on the OPU 17 control is carried out with the OPU or VPU. Management from both posts is equivalent, therefore, we will consider the option of control with the OPU.

To shift the gear to position B, press and release the command organ 22.

When the command body 22 (B) is pressed, the signal is input to the AND 34 input. If the N or XX commands do not work out, there are no command signals 31.1 and 33.1 at the And 34 input. According to the initial conditions at the input And 34 there are signals 12.1 (XX) and 15.1 ("emphasis of reversal"). The signal from the output And 34 is fed to the recording input of the memory element 35.

From the output of element 35, the signal 35.1 is fed to the input of And 30 and And 32, blocking the processing of commands XX and H, and to the input of OR 40.

From the output of OR 40, the signal enters the converter 41 (B), which supplies the working fluid to the right cavity of the servomechanism 6. The servomechanism 6 moves the gear shift control handle 2 at the local post 3 to position 4.1 (B). At the same time, the cam 8 closes the limit switch 11, which supplies a signal 11.1 to the reset input of the element 35. The system returns to its original state. To increase the engine speed, it is necessary to include the command body 19 in position 19.1 (B) and hold it in this position until the engine reaches the specified speed.

The signal from the organ 19 in its position 19.1 goes to the input And 43. If the input And 43 contains signals 11.1 (the gear is in position B) and 16.1 (the engine is running), the output signal And 43 through OR 45 receives a command signal to the converter body 46.1 46.

The Converter 46 delivers the working fluid through the throttle 49 to the right cavity of the servo mechanism 7, forcing the servo mechanism 7 to move the speed control knob 5 associated with it from the engine “rotation stop” to the position 5.2 (“maximum feed”). After reaching the specified speed, the organ 19 must be released and it automatically returns to the middle fixed position. Converter 46 fixes the servo mechanism 7 in the installed position using the built-in hydraulic lock in the converter.

To reduce the engine speed, it is necessary to turn on the command body 19 in position 19.2 (M) and hold it in this position until the engine reaches the specified speed.

The signal from the body 19 in its position 19.2 enters through the OR 51 to the input And 52. If the servo mechanism 7 is not in the "stop reverse" position, at the second inverse input And 52 there is no signal 15.1 from the limit switch 15 and a signal appears at the output And 52, coming through OR 53 to the organ 46.2 of the Converter 46.

The Converter 46 delivers the working fluid to the left cavity of the servo mechanism 7, and from the right cavity of the servo mechanism the working fluid enters through the throttle 49 and the Converter 46 to drain.

The servo mechanism 7 with a given speed moves the associated handle 5 to control the engine speed to reduce the fuel supply.

After reaching the specified speed, the organ 19 must be released, and it automatically returns to the middle fixed position. Upon arrival of the servomechanism 7 in the position of "emphasis of reversal" moving it stops.

With the help of the organ 19 in position 19.2, you can stop the engine, but this operation is allowed only when gear 2 is in position XX (handle in position 4).

To do this, press and release the organ 21 (XX).

The signal from the output of the organ 21 goes to the input And 32. If there is a signal 15.1 on the other direct inputs And 32 on the engine in the "reverse reversing position" and through OR 56 signal 11.1 or 13.1 on the engine gear in the B or H position, and on the inverse inputs And 32 there are no signals about the development of the system in position B (31.1) or in position H (35.1), the output And 32 there is a signal fed to the recording input of the memory element 33.

From the output of element 33, signal 33.1 is received to block the passage of commands to enable transmission to position B or H, and through OR 39 to the input OR 37 and 40.

From the output of OR 37 and 40, the signals 37.1 and 40.1 are simultaneously transmitted to the converters 38 and 41, while the servomechanism 6 and the handle of the caliper 3 connected with it are moved to position 4 (XX).

In this case, the signal 12.1 is fed to the reset input of the memory element 33 and the circuit returns to its original position to execute the next command.

After that, when the organ 19 is moved to position 19.2, the signal from the output 19.2 is fed to the input And 50. The other inputs And 50 receive the signals 15.1 (the engine is on the "stop reverse") and 12.1 (transmission in position XX). When these conditions are fulfilled, a signal appears at the output of AND 50, which goes to the recording input of the memory element 54, from the output of which the signal is transmitted through OR 53 to the organ 46.2 (M) of the converter 46, which at a given speed translates the servomechanism 7 and the associated motor handle into position 5.1 ("zero feed").

When the engine is stopped, the signal 16.1 is removed from the inverse input of the reset of the memory element 54 and the circuit returns to its original position.

To prepare the engine for start-up, it is necessary to move its fuel supply control handle to position 5 ("reverse stop").

To do this, the body 19 must be moved to position 19.1 and released.

The signal from the output 19.1 goes to the input And 42.

The other inputs AND 42 receive signals:

- direct entry - 12.1 (transmission in position XX);

- to the inverse input - there is no signal 15.1 (the motor is not in the “reverse reverse” position).

Under these conditions, the signal from the output of AND 42 is fed to the recording input of the memory element 44. From the output of the element 44, the signal through OR 45 is transmitted to the organ 46.1 of the converter 46 and through OR 47 to the converter 48.

The servomechanism 7 at high speed moves the speed control handle to position 5. In this case, the signal 15.1 is fed to the reset input of the memory element 44 and the circuit returns to its original position.

To switch the gear from position XX to position H, you must press and release the organ 20. The signal from the output of the organ 20 is fed to the input And 30.

If the other direct inputs And 30 there are signals 12.1 (XX) and 15.1 ("emphasis reverse", and on the inverse inputs of the IZO there are no signals 35.1 and 33.1 about the execution of commands B and XX, from the output And 30 the signal goes to the recording input of the memory element 31 , and from its output through OR 37, the signal 37.1 is supplied to the converter 38, forcing the servomechanism 6 to translate the engine transmission handle to position 4.2 (Н).

The input input reset element 31 receives a signal 13.1. The circuit comes to its original position.

To quickly reduce the engine speed, you must press and hold the organ 23. The signal from output 23 goes to the input OR 55, and from its output to the inputs OR 47 and 51. From the output OR 47, the signal goes to the converter 48, which provides a high speed of movement of the servomechanism 7 From the output of OR 51, the signal goes to the input of the And 52 element, from the output of which through OR 53 the signal goes to the organ 46.2 (M) of the converter 46, which includes a servo mechanism 7 to reduce the fuel supply.

Quick development is performed until the signal And 15.1 ("emphasis of reversal") appears on the inverse input of the And element 52.

If you need to quickly switch gear 2 from position B to position N (fast reversal of the running engine) to the body 20 (N) is connected to the quick reversing unit 56.

When you press and release the organ 20, if the reverse gear reduction is in position B (the gear control handle is in position 4.1), and the engine speed is determined by the position of the handle in any position from 5.2 ("maximum feed") to 5 ("reverse stop "), the signal from the body 20 enters the inputs And 57 and And 58.

If the engine operates in position B and at a speed allowed to disengage the gear to position XX (signals 11.1, 16.1 are present at inputs And 57 and there is no signal 16.2), and there are also no testing commands for shifting the gear to position XX (33.1) and to position B (35.1), a signal appears at the output AND 57, which is fed to the recording input of the memory element 59.

From the output of the memory element 59, the signal 59.1 is fed to the input of the elements And 60 and 61 and OR 55.

From the output of OR 55, the signal is supplied to rapidly reduce the engine speed to the "stop of reversal" (the appearance of signal 15.1), as described previously, if the engine was running at a speed above the "stop of reversal".

Since the transmission is still in position B, there is no signal 12.1 (XX) at the second inverse input And 60 and at the direct input And. 61.

From the output AND 60, the signal goes to the recording input of the memory element 62, the output of which the signal 62.1 through OR 39 and OR 37 and 40 is fed to the converters 38 and 41, translating the servomechanism 7 to position XX (signal 12.1 appears).

The signal 12.1 is fed to the reset input of the memory element 62 and to the input And 61.

If a signal 15.1 is also present at the input And 61, a signal appears at the And 61 output, which passes through the first time delay element 63 to the recording input of the memory element 64.

The delay after switching gear to XX is necessary to equalize the engine speed, which increases spasmodically when gear is turned off in position XX from the engine power take-off shaft.

When the operator gradually changes gears (B-XX-H - described above), the delay for XX when the gear is in position H is assigned to the operator.

From the output of the element 64, the signal 64.1 is transmitted through OR 37 (signal 37.1) to the converter 38, which transfers the servomechanism 6 to position N (signal 13.1). The signal 13.1 is fed to the reset input of the memory elements 59 and 64, stopping the development of the system.

If the engine operates in a position higher than that defined by signal 16.2, that is, there is no permission to disable transmission to position XX, input AND 57 is blocked by the presence of signal 16.2, and output AND 58, the signal goes to the recording input of memory element 65.

From the output of element 65, the signal is fed to the inverse input AND 57, blocking it during further processing of the signal, and to the inputs AND 66 and 67, as well as to the input OR 55 of the circuit for rapidly reducing the engine speed.

After reducing the engine speed before removing signal 16.2, signals appear at the output of And 66 and And 67.

From the output And 66, the signal goes to the recording input of the memory element 68, the output of which the signal 68.1 is fed through OR 39 and OR 37 and 40 (signals 37.1 and 40.1) to the converters 38 and 41, translating the servomechanism 7 to position XX. The signal from the output of the memory element 68 is removed when a signal 12.1 (XX) is received at its input.

From the output AND 67, the signal is supplied to the second input delay time element 69.

The time delay is necessary so that the object on which the engine is mounted, for example, a vessel, extinguishes its inertia, so that when the gear is in position H, the engine does not stall from the torque applied to its output shaft and to ensure effective braking of the object due to operation engine through a gear engaged for braking an object.

From the output of the element 69, the signal through AND 70 is fed to the recording input of the memory element 71.

The other inputs And 70 receives signals 12.1 (XX) and 15.1 ("emphasis reverse").

From the output of element 71 (signal 71.1), the signal enters through OR 37 (signal 37.1) to converter 38, which transfers the servo mechanism 7 to position H (signal 13.1).

The signal 13.1 is fed to the reset input of elements 65 and 71.

Testing the team ends.

Thus, the application of the proposed system will improve the reliability and speed of the system when controlling the engine and eliminate operator errors during the rapid reversal of a multi-engine installation of a transport object.
