Description

element AND 5. The output of the element OR 8 is connected with the input of the relay 2 of the vigilance handle. The output of the first element And 3 through the time delay unit 9 is connected to one of the inputs of the third element And 10. The output of the element And 10 is connected to the input of the electro-pneumatic deceleration valve 11. The second input element And 10 is connected to the output of the trigger 12 of the control of the start of movement. Input installation trigger 12 in the resolution position is connected to the output of the switch 13 throttling. Input installation trigger 12 in the prohibit position is connected to the output of the fourth element And 14. One of the inputs of the element And

14sv is engaged with the output of the differentiating unit 15. The input of the differentiating unit

15 is connected to the output of the switch 16 reverse forward. The second input element And 14 is connected to the output of the red-yellow fire decoder 17 signal indications. The output of the enable signal of the decoder 17 signal readings connected to the control input unit 1.

The output of the element HE 4 is connected to the input of the unit of the preliminary light signaling.

The device works as follows.

When the handle of the reverse switch is moved to the forward position, a signal is sent to the differentiating unit 15 From the output of the differentiating unit 15, in the presence of an enable signal and the output of the red-yellow light of the decoder 17 of the signal readings, the signals through the logic element I 14 are fed to the input of the trigger 12 installation to the position where there is no enable signal at its output

In the absence of periodic checks of vigilance from the output of block 1, an enabling signal is given. At this turn 2, the handles of alert are de-energized and there are decisive signals at both inputs of the logic element And 3. Respectively, from the output of the element 3, a signal is supplied to the block 9 of the time delay, from the output of which the signal goes to the second input of the 1/110 logic element. Since there is no resolution signal on its other input, it is also connected to an electropneumatic valve. 11, no power enable signal

The driver switch 13 Fogenich sends a signal to the input of the installation of the trigger 12 in the resolution position. Cm from the trigger output goes to the first And 10 element, by the signal t m.ixo / ui

which is powered by an electropneumatic valve 11.

The signal from the output of the block 9 time delay is also fed to one of the inputs

of the logic element AND 5. From the output of block 1, the signal goes to the logical element NOT 4, the output of which is connected to the second input of the logic element 5, the enable signal is absent, therefore

0 there is no enabling signal at the output of the logic element AND 5, regardless of the presence of a signal at the output of block 6, connected with the output to another input of the logic element L 5.

5 Therefore, in the absence of vigilance checks, reflex presses by the machinist vigilance handles do not lead to a change in the state of the device.

When entering the next team

0, the driver’s vigilance check from the output of block 1, the resolution of the solution disappears, therefore the resolution 4 is not available at the input of the logical element 4 and the resolution 3 also does not exist at the first input of the element VI 3. From the exit

5 of the logical element 4, the signal is fed to the second input of the logical element 5 and to the input 18 of the preliminary light signaling unit. Since the output of the logic element And 3 signal resolution

0 no, then at its output, connected to the input of block 9 of the time delay, there is a prohibition signal. At the output of block 9, the time lasts for a certain time is preserved, the previous state

5 (enable signal). Accordingly, at the two inputs of the logical element 5 there are permission signals.

Responding to the pre-light signaling lamp fire, the driver presses the alert handle, block 6 of which sends a signal to the third input of the AND5 logical element. Since all the inputs of the AND5 logic element have permission signals, then the output with the input of the logical element OR 9, there is also a resolution. Accordingly, at the output of the OR element, connected to the relay 2 of the alert handler, there is also a enable signal.

0 The relay 2 of the alert handler is turned on, and at its direct output, an enabling signal arrives at block 1. At the output of block 1 connected to the input of the HE 4, there is a enable signal, therefore the output of the HE is cleared, and the pre-warning light goes out,

If the driver did not have time to react to the pre-light signaling lamp ignition, then at the output of the time delay block 9 the resolution signal disappears. Therefore, at the output of the And 10 element, there is also no signal. Consequently, the electropneumatic valve is de-energized and its whistle is heard.

Since there is no resolution signal at the input of the AND 5 logic element, then pressing the alert handle associated with block 6 will not cause a change in the state of the device.

To interrupt the whistle, the driver must press the additional vigilance knob associated with block 7, the output of which is connected to the input of the logical element OR 8 is a enable signal. Consequently, there is a signal at the output of the element OR 8 connected to the relay 2 of the vigilance handle. The watchdog relay is turned on, and on its direct output, a enable signal arrives at block 1. As a result, the device returns to its original state.
