The drawing shows a structural diagram of a device for automatic locomotive alarm

The automatic locomotive signaling device consists of a locomotive receiver having a coil receiver 1 with a preliminary strip amplifier, and a decoder. The decoder includes: power supply 2 with overload protection circuits, differential amplifier 3 with automatic gain control, 4 pulse shaper, 5 pulse and pause selector 5, 6 pulse counter, comparison unit 7, register 8, locomotive signal inhibit block 9 in multiple traction mode, block 10 for automatically adjusting the brightness of signal lamps 5, block 11 for monitoring the vigilance of the driver, driver 12 pulses, block 13 for initial installation, block 14 for controlling the operation of electro-pneumatic Apaana, indika0 tion unit 15, signal lamps, combined with buttons injury vigilance alarm unit 16, a mode control button 17, an audio signaling unit 16, an electropneumatic valve

5 19, pressure sensor 20, timer 21, lamps 22 of an additional mode for checking the driver's alertness and multiple thrust mode 23.

The operation of the device is as follows.

An automatic locomotive alarm is automatically activated along with the start of the locomotive.

When installing the reverse drum

5 of the driver’s controller to the forward or backward position, the voltage from the contacts of this drum through the decoupling diodes is supplied to the power supply unit 2 and the control keys of the blocks 10 and 11.

0 block 13 and sends a reset pulse to the counter 6, block 9, block 7, register 8, block 11.

There is no need for additional actions by the driver (pressing the VK button, etc.).

5If there is no code and the unit is in good condition, a white light is on (white button). At a speed of more than 10 km / h (if a speed meter ZSL-2M or similar is installed) or another minimum

0

the speed gauge is adjusted, the driver’s alertness check begins in 15-20 s. The verification process is carried out as follows: at 15 (20) s, the backlight of the white button starts flashing. If the driver noticed this. he presses a flashing button, if he doesn’t notice, then an intermittent beep sounds after 8 seconds, and after 8 seconds (if this button is not pressed), power is supplied to the electro-pneumatic valve 19 Emergency braking occurs. The valve 19 can be switched off at a pressure in the brake line of less than 2 kgf / cm and is carried out by setting the reversing handle to the O position or by pressing the VK button.

Likewise, a vigilance check is performed under other lights or a change of lights. The difference is that the red light when the speed is exceeded 20 km / h, the auto-stop is triggered regardless of the will of the driver and the overspeed warning lamp is on. The same thing happens with a red-yellow signal, but with a speedometer of 60 / 00.80 km / h, the speedometer is adjusted, and a yellow signal - a periodic check of vigilance at speeds above 60/50, 80 km / h.

If the white light burns for more than 3 minutes of movement, then an automatic switch to vigilance is performed after 120 seconds. At the same time, the signal lamp 22 lights up. The mode is reset automatically when changing lights or when stopping, or manually - with the 17 VK button.

As soon as code pulses begin to arrive at the shaper 4, it begins to generate reset pulses for the counter

6, the rectangular pulses of the selector 5 and the code presence unit 9, as well as for the automatic gain control circuit in the amplifier 3.

The parameter control selector 5 is assembled on programmable counters and monitors the duration of pulses and pauses by minimum and maximum. Pulses that have passed control at a minimum arrive at counter 6 and are subject to accounting. The same thing happens with pauses.

Pauses that have passed the minimum control are counted as counter 6. The counting results must match. This checks the block.

7, Moreover, the number of pulses in the code cycle is counted by block 6, and all this is compared on block 7. In case of mismatch of the number of pauses and pulses in one of

Claims (1)

The claims DEVICE FOR AUTOMATIC LOCOMOTIVE SIGNALING, comprising a locomotive receiver connected to receiver coils, a power supply, a register connected to an indication unit, a driver's vigilance control unit connected to an electro-pneumatic valve, and a speed sensor, characterized in that it equipped with a selector for pulse and pause durations, a pulse counter, a comparison unit, a timer, immersion shapers (interference), the conversion is performed When block 5 gives a signal to the block that the pulse is longer than Oh, it also happens to recount. If the pause is too long, then block 5 takes it as a code gap (code cycle boundary). In the case of complete coincidence of all the results of counting and control, the decrypted code is recorded in register 8. It contains the register itself for 3 bits and the trigger for ejecting fire is white / red, which is transferred to one of the provisions on the dependence on which burned the last fire - kraen / yellow, or lived million glen, from the output register the sieve is sent to the output keys of block 10, which light one of the lamps at the locomotive traffic light of block 15. These keys are affected automatic brightness control circuit. The adjustment is made using pulse-width modulation of the supply voltage. When crashes (incorrectly received code) at block 6, continue for 6 s. at the 7th second, timer 21 generates a reset signal from register 8. Pei istr is turned off, and a white light (after KZ-red) lights up at the locomotive traffic light of block 15. By means of block 12, register 8 is cleared if there is no code for 2.5 3 s. Block 12 is assembled on a single-sampling device with a restart, Block 9 is designed to turn off a decoder, if the locomotions are used as a pusher or a main gun at a multiple pull. Structurally, the device is mounted on the remote control of the driver or other accessible for the driver’s location, has a connector for connecting a speed meter and wires of hiccups and electro-pneumatic clamping. hitchhiking (56) USSR Copyright Certificate No. 1369971, cl.
