Description

a locomotive comprising a successively connected unit for differentiating the locomotive control signals, an amplifier driver and a highlight control (not shown). The locomotive control devices (not shown) and the output of the safety handle 9 are connected to the other inputs of block 8, which are also connected to one input of the time setting change unit 10, the other input of which is connected to one of the outputs of unit 8. This unit 8 is also connected to one of the inputs of the time relay 4, to the other input of which the output of the unit 10 is connected. One of the outputs of the block 8 is connected to the input of the relay 6 of the watchfulness handle. Time relay 4 is designed in such a way that one of the inputs is the input to the float circuit and the time of the driver element, and the other input is the input to control the intervals between successive vigilance checks, and in the absence of the control signal on the last of the specified inputs of the control signal by successive checks .15-20 s, and in the presence of such a signal - 60 s.

The block 10 for changing the time setpoint can be implemented, for example, in the form of a start circuit 11, the time of the master circuit 12, the threshold, the element 13 and the accelerated discharge circuit 14, the start circuit 11 being connected by input to one output of the locomotive control signal 8 and the output is connected to one input of the timing circuit 12, another input of which is connected to the output of the accelerated discharge circuit 14 connected by the input with the handle 9, the output of the timing circuit 12 is connected to the input of the threshold element 13 whose output is connected to the input G of the relay 4 time exposure.

The device works as follows.

Unit 1 receives the locomotive signaling signals from the track circuit, amplifies them and transmits to unit 2. The latter decodes the received signals and ignites one of the lights of the locomotive traffic light 3 corresponding to the received signal. At the same time, unit 2 connects time delay relays 4, depending on the fire locomotive traffic light 3, either directly to the power source or to capacitors (not shown), which slow down the operation of time relay 4. The charging of capacitors after switching off the relay 4 times during periodic checks of vigilance is carried out with the help of the relay 6 of the alert handle when power is applied to it. Contacts

speed meter 5 is connected to time relay 4 in such a way that when the permissible speeds corresponding to the indications of a locomotive traffic light are exceeded, time relay 4 switches off. When the time relay 4 and the driver's vigilance checker b are switched on, when the lights of the locomotive traffic light of block 2 are changed, EPA 7 is powered.

The control signal generating unit 8 of the locomotive is open and operates as follows.

The signal at the output of the block 8, connected to the time relay 4 and time change block 10, occurs in the case of signals from the locomotive control devices, if there is no single or intermittent check, and the signal at the output of block 8 connected to the relay b vigilance handles occur when you press the vigilance handles

If the locomotive driver is not operating at his respective inputs of block 8, connected to the locomotive control devices, there is no signal and, accordingly, there is no signal at his outputs. If a periodic or one-time vigilance check signal is received, which is accompanied by the shutting down of EPA 7, then when the typist handles the alert 9 knob at the output of block 8 connected to relay b, a signal appears that activates this relay. In this case, if a regular periodic vigilance check was made, then the time relay 4 is turned on and the charge of the master circuit of this relay 4 is restored with a vigilance check period of 1520 s. If a one-time vigilance check was performed, the driver’s vigilance check relay is switched on when the lights of the traffic light are changed. In the decryption unit 2, when the locomotive control operation is performed by the mini-driver, a signal appears at the corresponding input of the generating control signal 8 of the locomotive, resulting in a change in the time setting at the output of the 8, connected to one of the inputs of the relay 4, and A 1-2 second signal appears.

Claims (2)

This signal in the relay 4 times recharges the capacitor of the master circuit time, and in block 10 acts on the trigger circuit 11, which causes the charge circuit of the master circuit 12. During this discharge time, the master circuit time .12 for 60 s at the output the threshold element 13 there is a signal acting on another input of the relay 4 time and switching interval between successive vigilance checks from 1520 s to 60 s. If during this time interval the driver performs another operation to control the locomotive, then the capacitor time, the driver circuit of the time relay 4 is recharged again, the time driver circuit 12 in block 10 will also restore charge and, accordingly, the last time the relay 4 will be for 60 s, a signal is present that provides a watchout check interval of 60 s for a relay. If a single vigilance check arrives all over the locomotive control actions, then to restore the power supply of EPA 7, the driver presses the vigilance handle 9. In this case, a signal appears at the input of the accelerated discharge circuit 14 in block 10 of changing the time setpoint, which provides a quick discharge time for the supply circuit 12. At the output of the threshold element 13, the signal disappears and, in 4 times, the interval between vigilance checks switches from 60 s for 15-20 s. If, after the locomotive control action, the driver reflexively presses the handle 9, the interval between vigilance checks will also automatically switch to 1520 s. If the signal from the locomotive control unit coincides with the regular periodicity or a single vigilance check, the signal at the output of the unit 8 does not appear, since the signal at the output of the relay is 4 times depleted and connected to EPA 7. And to one of the inputs of block 8. At the same time, EPA 7 is also turned off to cancel the forced braking of the driver It is important to press handle 9 regardless of whether it produces control over the locomotive. . Thus, the device extends the functionality and improves the efficiency of the driver’s vigilance checks by changing the vigilance check interval depending on the driver’s work. With ems, the total number of checks of the alertness of the awake and active driver is reduced, which contributes to the improvement of traffic safety:. Claim 1.
