Description

Vehicle stop display

1 is a schematic configuration diagram of an apparatus of the present invention.

2 is a detailed circuit diagram of the device of FIG.

The present invention relates to a display device that can display the stop of the vehicle running along a predetermined route to the passengers in the vehicle, and in particular, to display the passengers in the Korean, English and English during the temporary stop of the race route, such as subway, train and ship The present invention relates to a display device that enables passengers to recognize where they are at the same time by displaying the current operating position on the route during operation, as well as locals and foreigners.

Conventionally, vehicles on regular routes guide the stops by voice, but they are not only broadcast in our language, but also the voices are not clear, which is insufficient for the guidance of passengers and is incomplete for foreigners who do not understand Korean well. There was a drawback to being a guide or service.

In particular, in Korea, international events such as the 86 Asian Games and the 88 Olympics are expected, so in order to instill the impression that foreigners receive quality service in Korea and at the same time leave a good domestic impression, the first means of transportation, trains and buses It is necessary to get enough guidance.

The present invention is to meet the demands of the times, in particular to display the current operating position of the regular line vehicle in the car so as to avoid the disadvantages of the conventional so that it can be clearly seen visually so that both domestics and foreigners can easily use the general transport car An object of the present invention is to provide a vehicle stop display device, which will be described in detail with reference to the accompanying drawings.

First, the present invention will be described with reference to FIG. 1, and the input control unit 1 automatically generates a designated address data signal in the order of stop. The output of the input controller 1 is connected to the input of the parallel / serial converter 3 so that the address output at the input controller 1 is converted into a serial signal.

In addition, the manual control unit 2 is configured to generate the designated address output of each stop manually.

At the same time, when the operation of the manual control unit starts, the input control unit 1 is deactivated so that the designated address output of the manual control unit is input to the parallel / serial converter 3 to be converted into a serial signal output. In other words, if the 6-bit outputs of the input control unit 1 and the manual control unit 2 are used as wiring, the wiring is complicated and difficult to construct. Therefore, the 6-bit output is input to the parallel / serial converter 3 to convert to a single wire output. Amplify and output in 4) to simplify the device.

The main control unit (a) consisting of the input control unit 1, the manual control unit 2, the parallel / serial converter 3, and the output stage 4 is provided in the driver's seat or the driving vehicle of the vehicle. The output signal amplified by the output terminal 4 is applied to each display section (b).

Each display section (b) is composed of a receiving end (5), a serial / parallel converter (6), a memory (7), a current operation position display section (8), a text display control device (9), and a text display section (10). The receiver 5 receives the output from the output 4 to control the noise component and then supplies this signal to the serial / parallel converter 6.

In the serial / parallel converter 6, the input signal is converted into a 6-bit parallel signal and applied to the memory 7.

The 6-bit parallel signal becomes the address input signal of the memory 7. Accordingly, the memory 7 generates an output of the corresponding address and applies it to the current driving position display unit 8 to indicate where the vehicle is currently located. At the same time, it is applied to the character display control device 9 to input an address of the read-only memory built in the character display control device 9, and displays the character pattern generated in the read-only memory on the character display unit 10.

Continuous scanning is performed in the row of the switch matrix 201 by the continuous scanning part a consisting of (218-223, 248 and 252) and flip-flops 239-242.

This results in applying a high voltage to each of the rows sequentially, so that the potentials appear sequentially in the resistors R ₁ -R ₈ that ground the switch matrix 201. This sequential voltage is an encoder consisting of an inverter 253-264, 286-289, an OR gate 265-276, a NOR gate 277-280, an AND gate 282-285, and a NAND gate 281. As noted in Fig. 6, the sequential voltage is ignored and its output signal is determined according to the switch state in the switch matrix 201. In addition, the synchronization signal of the continuous scanning unit a is applied to one side input of the NOR gate 252 through the line d.

In addition, since the switch 115 supplies the power supply voltage V _H to the control selectors 107 and 114 to select whether to operate the control selectors 107 and 114, the switch 115 is automatically and automatically. You will have the ability to select manual.

Incidentally, the rising and falling counters (d) in FIG. 2 c are inverters 116-142, NOR gates 143, 153, NAND gates 154-177, AND gates 179-184, (flip-flop, 185-192 and switches 193-196, where switches 193 and 194 are for determining the initial value at which number to start counting, and switch 195 for selecting rising and falling coefficients. Switch 196 is a switch that operates once each time a bus or train commutes to a designated stop or station.

The pulses generated once by the switch 196 are applied to the flip-flops 185-192 through the inverters 141, 142, 122, 135 and the NOR gates 144, 150. Therefore, the result counted in the flip-flops 185-192 is applied to the analog switches 102, 104, 106, 109, 111, and 113 of FIG. 2B through the inverters 117-120, 132-133.

The signals through the analog switches 101-106 and 108-113 are converted into serial signals through the parallel / serial converter 3.

The capacitor C ₄ is adjusted to be equal to the clock period of the clock signal generator wh in FIG.

Therefore, a signal serialized in synchronization with the clock signal of the clock signal generator (wh) is converted into a parallel signal with the same synchronization. Since the signals appear in parallel at the output Q of the flip-flop 628-633, these signals are input to the address inputs A ₀ -A ₅ of the ROM 701 through the buffers 640-645. Since the serial-to-parallel converter is known in the art, further description of the operation will be omitted.

The ROM 701, the inverter 702-707, the NOR gates 708-713, the NAND gates 714-721, and the buffers 722-729 constitute the decoder 7, and the ROM 701 has a parallel signal. The inputs A ₀ -A ₅ are taken as address inputs to generate corresponding outputs D ₀ -D ₅ . Here, the inverters 702-707, the NOR gates 708-713, the NAND gates 714-721, and the buffers 722-729 form a counter, and the counter s of the ROM 701. to the output (D ₃ -D ₅₎ as input and generates the eight outputs of the NAND gate (714-721), respectively.

The current position display section 8 includes inverters 80 1-808, 826-835, NOR gates 809-815, NAND gates 816-825, resistors R ₃₆ , R ₅₆ , and transistors 837-837-. 19) and eight coefficient display stages (°) composed of photodiodes 836-836-19 are assembled. This causes any one of the photodiodes to light up to indicate the current behavior of the vehicle, depending on the current position of the vehicle.

That is, when 80 photodiodes are installed on a route display line and the corresponding photodiodes are turned on, the passengers can be informed where they are on the route. The 6-bit output of the ROM 701 is input to the lower input A ₆ -A ₁₁ of the ROM 957-959 of FIG. 2 f via the line S. FIG. ROM 957-959 includes flip-flops 901-906, inverters 907-917, 924-9 31, NOR gates 932-938, NAND gates 933-947, and buffers 918-933, 948. The character display control apparatus 9 is comprised together with -956. The output from the flip-flop 901-906 is supplied to the input A ₀ -A ₅ of the ROM 957-959.
