Description

Dead-man control system of railcars

The present invention relates to a driver boundary system for railroad cars.

In general, a driver boundary system installed in a railroad vehicle is a device for preventing a driver from sleeping while driving. As shown in FIG. 2, when the driver steps on the footrest, the contact A (FSa) is turned on and the foothold is stepped on and then released. A foot switch 20 in which the contact FSb is turned on; A two-minute time limiter (VDTR1) for exciting two minutes after the B contact (FSb) of the scaffold switch 20 is turned on to turn on the A contact (VDTR1a); A two-second time limiter (VDTR2) for exciting two seconds after the A contact (FSb) of the scaffold switch 20 is turned on to turn on the A contact (VDTR2a); A warning light (30) which is turned on when the contact A (VDTR1a) of the 2-minute time limiter (VDTR1) is turned on or the contact A (VDTR2a) of the 2-second time limiter (VDTR2) is turned on; A buzzer (40) for generating a warning sound when the contact A (VDTR1a) of the two-minute time limiter (VDTR1) is turned on or the contact A (VDTR2a) of the two second time limiter (VDTR2) is turned on; A 5 second time limiter that turns on the contact A (VDTR3a) when 5 seconds have elapsed after the A contact point VDTR1a of the 2 minute time limiter VDTR1 is turned on or when the A contact point VDTR2a of the 2 second time limiter VDTR2 turns on (VDTR3) and; When the contact A (VDTR3a) of the five-second time limiter (VDTR3) is turned on, the excitation is activated to turn on the contact A (VDRa), and includes a driving boundary relay (VDR) for operating the emergency brake. As follows. Here, the warning lamp 30, the buzzer 40, the two minute time limiter (VDTR1), the two second time limiter (VDTR2), the five second time limiter (VDTR3), and the driving boundary relay (VDR) As shown in Fig. 2, the position of the reverse electric machine 10 which determines the traveling direction of the railway vehicle is excited or actuated by the power source B + applied when it is in the forward direction F.

In the conventional driver boundary system configured as described above, the time required for the driver to brighten the foot switch 20 once every two minutes and to brighten and release the foot switch 20 once during normal operation of a railway vehicle is 2 seconds. If it does not exceed the warning light 30 and the buzzer 40 does not operate, the emergency brake also does not operate.

However, if the driver does not step on the scaffold switch 20 again, even though the driver is brightening the scaffold switch 20 for more than 2 seconds or 2 minutes after stepping on the scaffold switch 20 once, the warning light 30 Lights up and the buzzer 40 emits a warning sound. That is, at this time, the contact A (FSa) of the scaffold switch 20 is turned on for at least 2 seconds or the contact B (FSb) is turned on for at least 2 minutes, so the contact A (VDTR2a) of the 2-second time limiter VDTR2 is turned on. The warning lamp 30 is turned on and the buzzer 40 generates a warning sound because it is turned on or the contact A VDTR1a of the two-minute time limiting circuit VDTR1 is turned on.

As described above, if the driver presses and releases the foot switch 20 within 2 seconds before 5 seconds after the warning light 30 is turned on and the buzzer 40 generates a warning sound, the 2 second time limiting relay VDTR2 Since both the contact A (VDTR2a) and the contact A (VDTR1a) of the two-minute time limiter (VDTR1) are turned off, the warning lamp 30 and the buzzer 40 stop operation, but the footrest switch (5 seconds has elapsed). If step 20) is not pressed once within 2 seconds and then released, as shown in FIG. 2, contact A VDTR3a of the 5 second time limit relay VDTR3 is turned on to excite the driving boundary relay VDR. Since the contact point VDRa of the driving boundary relay VDR is turned on, an emergency brake (not shown) of the railway vehicle is operated to stop the vehicle. In this case, too, if the driver presses and releases the scaffold switch 20 within 2 seconds, the emergency brake stops operation, and thus the vehicle operates normally.

However, the conventional driver's boundary system as described above has always stepped on the scaffold switch 10 periodically to prevent the emergency brake from being automatically operated even when the driver does not sleep and normally handles various devices of the railway vehicle. Not only does the driver feel psychologically burdened and easily fatigued, but also the other device (eg, a daytime controller) while stepping on the foot switch 10 to stop the operation of the warning light 30 and the buzzer 40. , The brake controller, radio, etc.) missed the operation time, there was a problem that the device malfunctions can interfere with the safe operation.

Accordingly, in order to solve the above problems, the present invention prevents the warning light, the buzzer, and the emergency brake from being operated even when the railroad driver does not doze off and repeatedly presses and releases the footswitch during normal operation. Its purpose is to provide a driving alert system for a vehicle.
