Vehicle stop automatic guidance device

1 is a circuit diagram of the present invention.

2 is a view illustrating a time chart of a guide device according to driving and stopping of a vehicle according to the present invention.

The present invention relates to a vehicle stop point automatic guide device for automatically providing a stop point to the passengers in the vehicle, such as a bus or train, and at the same time to automatically display the stop point and advertisements.

Conventionally, the guide device of a vehicle has a stop name written on a route guide board to be driven mechanically or electrically, or manually operated to display a stop point. It has been pointed out that a problem that causes driving accidents by disturbing driving behavior has been pointed out, and when a stop point of a vehicle is displayed or broadcast differently due to a wrong operation, there is a defect that embarrasses a passenger.

The present invention is to calculate the mileage of the vehicle using a microcomputer in order to solve the above problems and defects, and to automatically display the next stop point and advertisement when driving a certain point and announcements by simultaneous broadcasting In particular, it allows the microcomputer to store in advance the distance (m) before and after the vehicle stops from the first starting point, and when the train or bus approaches the stop point, broadcasts the stop point and stops it. When you arrive nearby, open the door to get on and off the passengers, and then close the door so that the next stop point is displayed in Korean and English on the LED metric indicator. Is done automatically.

Also, while the vehicle starts and displays the next stop point on the LED metrics display, the advertisement display and the current time display are alternately displayed in the up date, so that the passengers can enjoy the double effect of the advertisement and advertisement.

When described in more detail by the accompanying drawings as follows.

That is, the interface adapter PIA of the microcomputer MC, which connects the output of the mileage dividing counter IC ₁ to the set terminal S of the flip-flop FF ₁ , and outputs the output data KMI thereof. Input to the OR gate (OR ₁ ) and the pulse of the trigger pulse generating circuit (T ₁ ) through the door open / close switch (S ₁ ) or the data (AST) of the interface adapter (PIA). The output of the flip-flop FF ₂ set from the data BST of the PIA is connected to the input terminal of the AND gate AND ₁ , and the output thereof is a reset terminal R of the flip-flop FF ₂ . and the data of the flip-flop (FF ₃₎ set stage and coupled to (S), the flip-flop (FF ₃₎ interface, the output of the adapter (PIA) input terminal connected Sikkim the same time, the interface adapter (PIA) to (CID) of the ( AAO operates the flip-flop FF ₄ and the amplification circuit AMP to be input to a known broadcasting device player AAA and drives the LED display. Outputs (A, B, C, D) from the interface adapter (PIA) for connection to the latch decoder (IC ₂ ), through the inverter (IN ₁ ) (IN ₂ ) (IN ₃ ) known LED While connecting one side of the dot matrix indicator LM, the other outputs 1, 2, 3, ... 8 of the interface adapter PIA are flip-flop latch ICs LT _1-a , LT _{1-b to} LT. _10-a , LT _10-b ) sequentially connected in parallel, enable of the interface from the adapter (PIA) through the latch decoder (IC ₃ ), the flip-flop latch (LT _1-a , LT) The outputs of _{1-b to} LT _10-a and LT _10-b are connected to the longitudinal axis of the LED indicator LM through the heavy amplifier AMP ₁ .

In the above, the door opening and closing switch (S ₁ ) is a door open, closed detection switch, such as subways and buses, and in the case of a railroad car, there is no door open, closed detection switch, so the speed meter speed is zero (during stop). It can be used by replacing with zero speed detector contact.

In addition, the known LED indicator (LM) is a collector display method that displays the station name, current time, advertisement, etc. in Korean, numeric, English, etc., and consists of 16 × 16 dot matrix per collector. The circuit is a drive circuit, and the latch circuits IC ₂ and IC ₃ are driven to the high level (hereinafter referred to as "H") by the data CID of the flip-flop FF ₃ . Each LED of the is off. In addition, a mileage counter (not shown) is connected to an input terminal of the mileage dividing counter IC ₁ .

In the figure, R ₁ is the input resistance of the trigger pulse generation circuit (T ₁ ), L ₁ is the display lamp, and R ₂ to R ₁₇ are between the latch decoder (IC ₂ ) and the inverter (IN ₁ ) (IN ₂ ) (IN ₃ ). Resistor for voltage safety, RST is reset, Key ₁ is ten key board, CPU is central processing unit, RAM is random access memory, ROM is read-only memory.

Effects of the present invention configured as described above are as follows.

First, as shown in FIG. 2, the city hall, the Jonggak… In the case of regular routes such as filing, the vehicle stop center point (①, ⑥, ⑪, ) Around 100m front and back (for example, ②, ⑤, ⑦, ⑩⑫, ) And stations (③, ④, ⑧, ⑨) are stored in ROM in the microcomputer MC, and the points (②, ⑦, ⑫, ) Is defined as LED display data and automatic broadcast output data (AAO) to update the next stop station after train departure, and the points (⑤, ⑩, ) Is the broadcast output (AAO) of the station (or station) at which the train arrives, and the data (BST) for preparing to update the display of the next stop on the LED indicator (LM), and the points (③, ⑧) Is for updating the advertisement and current time display, and the branches (④, ⑨) are designated as updates to display the next stop in the advertisement and are arranged as DSP (LED) shown in FIG.

In addition, DOC (T ₁ ) represents the pulse from the trigger pulse generation circuit (T ₁ ), MEM represents the pulse previously stored in the microcomputer (MC).

The first vehicle opens the door at Seoul Station (①, 00, 000) (the door opening / closing switch (S ₁ ) is in the Closed state), and the passengers get on and off, and an arbitrary number (eg 01) on the keyboard (Key ₁ ). Key in, the interface adapter (PIA) output data (BST) of the microcomputer (MC) sets the flip-flop (FF ₂ ), and its output is input to the AND gate (AND ₁ ) as a "H" signal. It is in the standby state, and since the door is opened above, the output of the trigger pulse generation circuit T ₁ remains unchanged. At this time, the display lamp L ₁ is displayed.

Afterwards, when the vehicle closes due to the departure time of the vehicle, the door open / close switch S ₁ is opened so that an output pulse is generated in the trigger pulse generation circuit T ₁ , and this “H” output is one side of the OR gate OR ₁ . The output of the OR gate OR ₁ is input to the input terminal as being "H", and this "H" signal is input to one end of the AND gate AND ₁ to match the output signal of the flip-flop FF ₂ . Together, the "H" signal is output to the output of the AND gate AND ₁ .

This signal is standing because thereby set a flip-flop (FF ₃₎ flip Sikkim the same time, set-flop (FF ₂₎ Li, the output of the flip-flop (FF ₂₎ is Low Level is (the "L" term), the output is The AND gate AND ₁ outputs the "L" signal. However, at this time, the output of the flip-flop FF ₃ outputs an "H" signal, and this signal is input to the microcomputer MC as data CID.

At this time, when the input data signal CID is input, the microcomputer MC turns off the display character of the "Seoul station" displayed on the LED display LM, and simultaneously outputs a reset signal RST to flip the flip-flop ( FF ₃ ) is reset. This is you from the Seoul vehicle in the same conditions as the running distance meter (not shown in the figure) is output from the start the counter and the distance traveled counter (not shown in the figure) is input to the frequency divider counter (IC ₁₎ frequency divider counter (IC ₁₎ Will generate a pulse every 10m of travel (when the dispensing counter IC ₁ is a 1/10 minute period).

The output pulse drives the flip-flop FF ₁ so that a pulse every 10 m is inputted by the flip-flop FF ₁ to the interface adapter PIA of the microcomputer MC, and the microcomputer MC. ) to reset the flip-flops (FF ₁₎ to transmit the acknowledgment pulse (RST) each time it receives a pulse on every flip-flop (FF ₁₎ and Kane receives the pulse of the next 10m.

By this process, the microcomputer MC calculates the actual driving distance of the traveling vehicle as known, and compares it with the previously stored point.

If the vehicle passes the point (②) of FIG. 2 while the vehicle is driving, the interface adapter (PIA) sends the output data (AAO) to flip-flop if the microcomputer (MC) is identical to the pre-stored 00, 100 (2) points. (FF ₄ ) is set, and its output is driven through an amplifier (AMP) to drive a known broadcaster player (AAE), for example sending out a broadcast saying "Next stop is a viewing station" and flipping by the end pulse of the broadcast. While the flop FF ₄ is reset, the interface adapter PIA output data includes the flip-flop latches LT _1-a , LT _{1-b to} LT _10-a , LT _10-b and the latch decoder as described below. The LED indicator (CM) is scanned by driving (IC ₂ ) (IC ₃ ), and the next stop is displayed as "viewing station".

In addition, when passing point ③ of FIG. 2, an interface adapter (PIA) output (AST) pulse is generated and input to one input terminal of the OR gate (OR ₁ ). Accordingly, the output " H " signal of the OR gate OR ₁ is input to the AND gate AND ₁ , but since the flip-flop FF ₂ is in a reset state, the output data CID of the flip-flop FF ₃ is not generated. There will be no change.

When the vehicle continues to travel and passes the point ③ of FIG. 2, if the same value as the 01300m (③) previously stored in the microcomputer (MC), the output data of the interface adapter (PIA) is flip-flop (LT _1-a , LT _{1). -b to} LT _10-a , LT _10-b ) and the latch decoder IC ₂ (IC ₃ ) are driven to erase the LED display of the "viewing station", and the advertisement text and the current time are displayed alternately.

At this time, the output data AAO of the interface adapter PIA is not transmitted.

Next, when the train passes point ④ of Fig. 2, the interface adapter (PIA) output data is updated from the above advertisement and the current time back to the "viewing station" data so that it is continuously displayed on the LED indicator (LM). At this time, the output data AAO of the interface adapter PIA is not transmitted.

After the vehicle passes point ⑤ of FIG. 2 approaching the "viewing station" stop point, the output data BST of the interface adapter PIA sets the flip-flop FF ₂ and its output "H" signal is the AND gate (AND _1). ) And the output of the door open / close switch S ₁ , that is, the output pulse of the trigger pulse generating circuit T ₁ , while the output data AAO of the interface adapter PIA sets the flip-flop FF ₄ . In this way, the broadcasting device player AAA is driven through the amplifier AMP to transmit a broadcast "This station is a viewing station", and then the flip-flop FF ₄ is reset as described above.

Next, when the vehicle stops near the stop of the city hall, opens the door to get on and off the passengers, and closes the door, the door opening / closing switch S ₁ is opened and the pulse is generated by the pulse of the trigger pulse generation circuit T ₁ . an OR gate (OR ₁₎ becomes the input to the "H" output signal, the OR gate (OR _1), the other end is already "H" signal is so been input output of the AND gate (AND ₁₎ is "H" signal is output It is done.

Accordingly, this output resets the flip-flop FF ₂ and simultaneously sets the flip-flop FF ₃ to send its output CID to the interface adapter PIA, and the flip-flop FF ₃ It is reset by the acknowledgment pulse RST of the microcomputer MC.

At this time, the microcomputer MC turns off the LED indicator CM in combination with the received data CID.

After that, the operation of the vehicle from the city hall station to the end station is repeated as described above. If the vehicle is a bus, there may be no passengers at the next stop.

In the operation state in this case, for example, the character of "starting" is currently displayed on the LED indicator LM, and the bus is shown in FIG. In the case of passing the point, the interface adapter (PIA) operates the flip-flop (FF ₄ ) to transmit a broadcast as described above. In addition, the output data BST of the interface adapter PIA sets the flip-flop FF ₂ and is input to one input terminal of the AND gate AND ₁ , and the other input terminal receives a signal of the door open / close switch S ₁ . I'm waiting. If there are no passengers to get on and off in Jegi-dong, the bus will pass through When passing the point, the "H" signal is output to the output terminal of the OR gate OR ₁ by the driving point data AST of the interface adapter PIA, and this signal is input to the other input terminal of the AND gate AND ₁ . The output signal of the AND gate AND ₁ sets the flip-flop FF ₃ . Therefore, the output data CID of the flip-flop FF ₃ is input to the interface adapter PIA, and the microcomputer MC of FIG. By combining the contact with the data (CID), the LED display (LM) to update the character of "Cheongnyangni", so that even if you pass through the stop without getting on and off passengers to automatically display the next stop.

On the other hand, the LED indicator LM is driven according to the data of each point while the vehicle is running. The interface adapter PIA applies the inhibit (INH) of the latch decoder (IC ₂ ) (IC ₃ ) to the "L" signal. The first output data (1-8) of the simultaneous interface adapter (PIA) is delivered in parallel from the flip-flop latches (LT _1-a , LT _1-b ) to (LT _10-a , LT _10-b ), but the latch the output (0) is a flip-flop latch _{(LT 1-a, LT 1} -b) to enable the flip-flop latch _{(LT 1-a, LT 1} -b) output of the decoder (IC _3), an amplifier (aMP ₁₎ Power is applied to the LED of the LED indicator LM from 1 to 8 on the node side, and the output of the latch decoder IC ₃ together with the second output data (1-8) of the interface adapter (PIA). This flip-flop latch (LT _10-a , LT _10-b ) is enabled and power is applied to the LED side of the LED indicator LM through the amplifier AMP ₁ according to the data input from the nodes 9 to 16. In the same way, play up to the tenth. The flop latch _{(LT 10-a, LT 10} -b) was applied to enable a power to the LED of the "A" column side of the LED indicator (LM).

The interface adapter (PIA) output data (A, B, C, D) drives the latch decoder (IC ₂ ) and its output (0) is the "A" column side of the LED indicator (LM) via the inverter (IN ₁ ). The negative portion of the LEDs is applied to the cathode side of all LEDs in parallel so that only the corresponding LED is displayed on the "A" column side.

The interface adapter (PIA) output data (1-8) then allows the new data to operate the flip-flop in this manner to display the "B" column of the LED indicator (LM), and the scan continues to the "P" column. Is displayed.

As described above, the present invention measures the mileage from the microcomputer according to the driving of the vehicle, and when the vehicle arrives at the stop point, the next stop station is displayed on the LED metrics display according to the door open / close switch or zero speed, and simultaneous announcement is performed. During operation between stations, advertisements, current time, etc. are displayed on LED indicators alternately, and the next station name and stop name are displayed to give the passengers more convenient service in accordance with autonomous times of getting on and off. It is a useful and practical design that can be provided.
