The present invention relates to an electronic pass and stop display circuit device, and more specifically, a light emitting device of various colors is installed on a stop display of a route guide map installed inside a vehicle used for passenger transport such as buses, trains and trains. It is an electronic pass stop display circuit device designed to allow passengers to easily know where the vehicle is currently operating.

In modern society, where more people travel to other areas for various purposes, the necessity of such a device has been required early, and thus, there is no route guidance display device. Nevertheless, in the case of the conventional mechanical device, it is too much focused on automation, and when the time or distance is set in advance for a certain time and the distance is driven, it is designed to automatically light on the display device by the action of a gear or a clock. Under heavy traffic, its effectiveness is so questioned that it has not been adopted in the field at all.

The present invention is to solve the above problems, the object of the present invention is to connect to the switch of the announcement using the existing tape, or independently, the driver reaches the stop guide point, the next stop with a single button operation It turns on the LED that indicates and the stop LED that has already passed is on, so that the passenger can easily know in which direction and how far.

Another object of the present invention is to use the various colors of LED to display the left and right doors in the subway, and to facilitate the passenger's convenience by displaying transit stations or important stops in different colors for both buses and subways. For that purpose.

Another object of the present invention is to provide a means that can be easily modified when mishandled due to inexperienced operation.

According to the structure of the present invention for achieving the above object, as shown in FIG. 1, the switch unit 30, which is composed of four switches that the driver operates, the switch 30 of the switch unit 30 is turned off Point and light out signal generator 42, direction signal generator 44, and switch unit 30 composed of two JK flip-flops that continuously supply the selected point, light and direction signals selected by (32) and direction switch (34). The on / off direction signal display unit 50 configured to light the switch when these switches are pressed so that the on / off switch 32 and the direction switches 34 of the " In order to be able to check the LED display unit one by one by pressing the progress switch 38, the progress signal display unit 60, the reset switch 36 configured to be directly operated by the progress switch 38 Manipulated and clicked Clear signal generator 40 for generating a signal, LED display unit 70 is configured to receive a signal from the advance switch 38 to turn on or off the LED 22 one by one, and not shown in Figure 1 but stable It consists of a power supply unit 80 for supplying power.

The operation of the present invention configured as described above will be described in detail with reference to FIGS. 3, 4, and 5 as follows.

When the initial power is applied to the circuit, the LED 22 of the LED display unit 70 may be unevenly lit due to the surge voltage. In this case, the reset switch 36 is pressed to generate a clear signal, which is illustrated in FIG. The LED sequence is sent to pin 9 of the lighting device 72-77 to initialize these devices. Then, after the direction is determined using the direction switch 34, the lamp is turned on using the point / light switch 32, and the advance switch 38 is pressed. The clock CLK signal generated at this time is the progress signal of FIG. The display unit 60 is driven to inform the passenger that the stop guiding operation is performed by sound and light, and at the same time, the clock signal activates the LED sequence lighting element 72 of FIG. 5 so that the LED connected to the corresponding pin is turned on. .

If the LED lights up unnecessarily due to the operator's mistake, press the direction switch 34 to change the direction, press the dot / light switch 32 to select the light off, and then move the switch to the desired position. Press 38) to turn off the already lit LEDs (22) in turn, and then press the direction switch (34) and the dot / off switch (32) once each to reach the desired point and change the direction again. You are done.

The JK flip-flops 42 and 44 shown in FIG. 3 each time the corresponding switches 33 and 34 are pressed, the signal generated by the JK flip-flop and the turn-off signal generator 42 and the direction signal are generated. S0 (1) and S1 (19) values of the LED sequence lighting element 72-77, which are inputted to the clock stage of the negative section 44 and alternately change the output values of Q and Q, are input to the signals of Q and Q. The values of, SL 18 and SR 11 are changed to perform the desired functions.

The LED sequence lighting element (72-77) used in the present invention used 74LS299, and this IC can turn on and off eight LEDs in order due to its characteristics, and if more or fewer LEDs are needed, 74LS299 can be realized by increasing or decreasing the device.

In addition, the present invention uses a known power supply circuit using a 723IC to step down the 24VDC voltage commonly used in vehicles to a DC 5V voltage suitable for this circuit. In order to increase the practicality of the present invention, the color of the LED can be diversified and used for displaying the left and right doors, or for displaying a large station or a transfer station that passengers use as a reference.

As can be seen from the above, the present invention can be used in circulation and linear round-trip sections, and it provides an easy means for the passengers to know how much direction they are traveling in one direction even if they wake up or wake up with a single switch operation. To the effect.
