Description

[Detailed description of the device] This device is installed in vehicles such as shared buses, sightseeing buses, and trains, and guides passengers to the next station during operation, such as "Next is Tokyo" and "10 minutes to Tokyo. The present invention relates to an in-vehicle guidance display device in which a display such as "I will arrive in a while" is displayed in text.

<Background> Conventionally, in vehicles such as buses, as methods of transmitting messages to passengers such as station guides and various guides related to operating routes, there are display methods by displaying printed materials and broadcast guide methods by in-vehicle broadcasting devices. It was However, the former has a problem as a display method performed in a narrow vehicle because the size of the printed matter to be displayed becomes large as the number of messages to be transmitted increases. In addition, it is difficult for the display method based on this notice to change the display contents over time as the vehicle runs. On the other hand, in the latter broadcast guidance method, it is necessary to repeatedly broadcast to passengers many times in order to transmit a complete message, and when the tape recorder is played back and broadcast, the amount of tape is large. Therefore, it cannot be said that it is an appropriate method for providing guidance for the next station name or advertising guidance, for example.

In order to solve these problems, the inventors have proposed to improve the service for passengers by displaying a guide with a dot type display, and the inventors have proposed Japanese Patent Application No. 56-140692 "In-vehicle display device", Japanese Patent Application No. 57-119037. No. "Guide display device" proposed. However, all of these proposals were used for general route operation. That is, these are all configured such that the distance between the stations is relatively short, and the guidance for passengers is also switched once or twice at the operating position of the vehicle between the stations. The signal used to switch the display can be a door opening / closing signal, a broadcasting device activation signal, a distance pulse signal, etc. It is convenient to use the activation signal of.

Since it is necessary to transmit a message different from the above contents in a long distance bus among the route buses, the activation signal of the one-man device cannot be used as it is for switching the display of the display device. In other words, since the distance between stations is long on long-distance buses, the boarding time between stations will be longer than before, and passengers will become bored with only regular station name display guidance on ordinary route buses, It is necessary to convey a service message. Therefore, it is required to improve the service effect for passengers by appropriately inserting service messages such as various advertisement information, tourist information near the operation route of the vehicle, and station arrival time information. However, as in the case of a general route bus, it is not possible to satisfy the display simply by using the display switching signal based on the activation signal of the one-man device.

The present invention solves the above-mentioned drawbacks of the conventional in-vehicle guidance display device, and provides an in-vehicle guidance display device which is mainly used for bus vehicles and automatically displays various types of guidance to passengers during operation. Is.

<Outline of Device> This device includes an input operation unit, a memory unit, a controller, and a display.

The input operation section is provided with a system designating switch for designating a vehicle operating system, a time switch for inputting the advance or delay of the vehicle operating time, and a start switch for instructing to start displaying various information on the operation of the vehicle. There is.

The display data memory unit stores guide information to be displayed for each operating system of the vehicle together with a display time or a display distance position to be displayed.

In the controller, the display item is read from the display data memory section by the instruction of the start switch by the system designation switch, the display time or display distance position is corrected based on the input of the time switch, and the corrected display time or display distance position is displayed. Transfer the display data to the display unit.

On the display, the characters corresponding to the guide information to be displayed are displayed in the dot mass matrix format based on the display data transferred from the controller.

Therefore, in the in-vehicle guidance display device of the present invention, it is possible to appropriately guide relevant information when a vehicle arrives at a station or starts from an arrival station and at a predetermined position between stations in a long-distance route vehicle with long station intervals. It is possible to display a guide in the vehicle at a timing. At the same time, the deviation of the operating time of the vehicle is displayed and guided, and the passenger can be provided with appropriate and sufficient guidance information.

<Embodiment> Hereinafter, an in-vehicle guidance display device of the present invention will be described in detail with reference to the drawings based on an embodiment thereof.

FIG. 1 shows the configuration of an embodiment of the present invention. The in-vehicle guidance display device of the present invention is roughly divided into an input operation section 1, a memory 2, a display 3, and a controller 4. The case where the in-vehicle guidance display device of the present invention is applied to a bus will be described below.

The input operation unit 1 is for the driver to control the in-vehicle guidance display. The input operation unit 1 provides a read command for a display group suitable for the vehicle operation system, a display start instruction, and a guide for each in-vehicle guide according to the operation status of the vehicle. A display time correction command can be issued by the input operation unit 1.

The input operation unit 1 is installed near the driver's seat of the bus, and is designed so that the driver can easily perform operations when controlling various displays. The input operation unit 1 includes a system designation switch 100, a start switch 110, a time switch 120, and a lead switch 13
0, delay switch 140, monitor 150, and input terminal group 160. The system designating switch 100 is used to select a desired destination display item from a plurality of operating system display items stored in the memory 2. For example, the system designating is performed by inputting a number with a digital switch.

The start switch 110 is a switch for instructing the start of display. The time switch 120 is a switch for setting the delay or advance of the operation time of the vehicle, and is operated by inputting a number with, for example, a digital switch. The advance switch 130 and the delay switch 140 are time switches, respectively.
It is a switch for inputting that 120 is ahead or that it is behind. The monitor 150 is a watch monitor, and the input terminal group 160 is used for displaying an interrupt by a running operation or the like.

The memory 2 is a part that stores data necessary for display,
A semiconductor element such as ROM or RAM or a magnetic bubble is used. In the memory 2, character pattern data necessary for display, display data for determining the character composition of the display message,
Display program data of display messages and the like are stored. In this case, the display program of the display message is created for each operation system of the vehicle, and the display start time data indicating the display order and the display time is incorporated in this display program. In this case, instead of the display time, display start distance position data indicating the display distance position to be displayed may be incorporated.

For example, in an efficient configuration example of a memory using a ROM as shown in FIG. 2, a pattern memory (ROM1) 200 for storing a character pattern as data and a display character corresponding to a display code are stored as a code. It is composed of a display code memory (ROM2) 210 and an operation data memory (ROM3) 220 in which the items to be displayed for each operation system are programmed and stored together with the display time according to the display order.

The controller 4 processes the command signal from the input operation unit 1 and the display program contents of the memory unit 2 and corrects the delay or advance of the vehicle operating condition to correct an appropriate time or display distance. The control is performed so that an appropriate message corresponding to each position is displayed. In particular, in a bus operating on a long-distance route, the controller 4 can display an appropriate guide in response to a change in traffic conditions.

The embodiment shown in FIG. 1 is a case in which the controller 4 is constituted by a microcomputer, and in addition to a central processing unit, which is a CPU 410 for sequentially reading and decoding and executing programs,
A readable / writable memory (RAM) 430 for work and data editing used for various calculation processes of the CPU 410, a memory (ROM) 420 for storing a control program, and a clock circuit 440 for controlling display time is a data bus. It is connected to 460. The input operation unit 1 is connected to the input / output ports 450 and 451 for the interface, the memory 2 is connected to the input / output port 452 for the interface, and these input / output ports are both controlled via the data bus 460. It is connected to the CPU 410 of the device 4.

The display device 3 displays various characters such as station names by the dot matrix method based on the character pattern data sent from the controller 4. In the display of this indicator 3, for example, "turn to the right" in conjunction with the operation of the direction indicator, "please be careful of sudden braking" in conjunction with the brake operation, when there is a correction command on the display Display of delay in "Display of 10 minutes behind" can be displayed while the station name or advertisement information is displayed.

The display device 3 is, for example, a lightning type display device using a plasma type dot matrix panel (hereinafter referred to as PDP), and has a configuration of 16 × 16 dot display for each character so that the PDP can display eight Chinese characters. For example, as shown in FIG. 3, the electrodes Y _{0 to} Y _{15 that} are extended in the horizontal direction indicating the vertical position have 16
A book and an electrode X ₀ that is extended in the vertical direction indicating the horizontal position
~ X _n-1 is 16 per character and a total of 128, and one electrode is provided for each space between characters, for a total of 128 + 7 = 1
Thirty-five are provided, in this case X _n-1 . electrode
Y _{0 to} Y ₁₅ and the electrodes X _{0 to} X _n-1 are provided so as to intersect with each other,
Characters are displayed by selectively emitting light at each of these intersections. In the example shown in FIG. 3, the black dot () is the light emitting display dot at the intersection point position.

FIG. 4 shows a display example of the in-vehicle guidance of the transmission message carried out by this invention. In this display example, the display is shown in the vehicle between Shin-Yokohama and Odawara in the operation system of operation system number 001 from Tokyo to Shin-Osaka. The displays 1 and 7 in FIG. 4 display the arrival station in conjunction with the signal generated when the door of the vehicle is opened. Indications 2 and 3 show the sights of the next station or its operating route corresponding to the programmed display time, and indication 4 shows an interrupt display by the signal of the turn signal. The message prompting you is displayed. Display 5 is a display for informing passengers of the delay of the vehicle operation by setting the delay time from the input operation unit, and Display 6 is a transmission message displayed corresponding to the programmed display time. However, the display content is adjusted and displayed based on the set time of delay or advance of vehicle operation from the input operation unit 5.

The transmission messages that are these display information are stored in the memory unit 2, and are stored in the ROM1, ROM2, ROM3 of the memory 2.
It is stored according to each function. The pattern memory 200 of the ROM 1 can read the pattern data of the corresponding character by the associated character code as shown in FIG. 5, for example, "A" can be read by the code of "01". Further, the pattern data uses dot patterns as data as shown in FIG. 6, and FIG. 6 shows a case where the character “East” is selectively displayed. In the display code memory 210 of the ROM2, as shown in FIG. 7, for example, the display code 030 for transmitting and displaying the message "I arrived in Shin-Yokohama" is the "new" character code 15,
A "horizontal" character code 71, a "beach" character code 52, etc. are stored. The setting of the display code in this case can be arbitrarily selected.

In the operation data memory 220 of the ROM3, as shown in FIG. 8, the data 221 indicating the system number 001 or 010 of the operation and the display order are sequentially programmed by the display code data 222 and the display time data 223 and stored. There is. The display code data 222 is represented by, for example, a 4-digit number, and the first digit “1” indicates that the data is the data displayed when the station arrives, and “0” indicates that the data is displayed between stations. Indicates. The lower three digits of the display code data 222 match the display code of the display code memory. This 1-digit number needs to be skipped when the vehicle arrives early due to the shortened operation time of the vehicle, and it is necessary to read it to automatically correct the disorder of the display order. Is. Further, A of the system data is a judgment code at the time of data reading, and indicates that the three digits following the A are system numerical values. The display time data 223 uses the display time from the start of vehicle operation as data, and is composed of, for example, two digits for time display and two digits for minute display, for a total of four digits. For example, 0115 indicates that it is displayed after 1 hour and 15 minutes.

The schematic operation of the in-vehicle guidance display device of the present invention, the construction of which is shown in FIG. 1, will be described below with reference to FIG.

When the power is turned on, the controller 4 is automatically activated at the same time, and the controller 4 starts operating. The CPU 410 sequentially reads the ROM 420 of the control program memory and decodes the memory. Initialization 1 is performed first. That is, the read / write memory RAM430 is cleared (setting of initial values) and the input / output ports I / O450, I / O451, I / O452 and I / O4
53 registers are cleared. Since the RAM 430 is cleared, the contents of the display counter address provided in the RAM 430 are set to the initial value 0. I / O port I /
The front surface of the PDP display 3 is cleared through O453.

In the next step 2, a number generally called a system of the route on which the vehicle is going to operate is set by operating the system designating switch 100. For example, when the system number 001 is manually input by the driver by the switch 100, the data is stored in the route address area of the RAM 430 via the input / output port I / O 450. Furthermore, various input signals can be input via the time switch 120, the advance switch 130, the delay switch 140, and the input terminal group 160.

In Step 3, the time when the vehicle starts operating is set,
For example, when the vehicle starts with a delay of 5 minutes from the operation schedule, the time switch 120 sets and inputs a time signal of 5 minutes, and the delay switch 140 is turned on. The operation time of the vehicle is monitored, and the delay time or the advance time of the vehicle is set and input by the time switch 120 every predetermined monitoring time, and the delay switch 140
Alternatively, when the advance switch 130 is turned ON, a shift in operating time is indicated.

In the next step 4, the start switch 110 is turned on to start the display read operation. The operation will start again. When the delay switch 140 or the advance switch 130 is turned on in step 3, the vehicle start time data is stored in the start time address area of the RAM 430. Also, the start switch 110 is turned on in step 4.
After that, in step 5, the timer of the clock circuit 440 is set and the clock is started. In step 6, the contents of the display counter stored in the RAM 430 are checked. As the display counter, one word of the display counter address of RAM 430 is assigned. That is, the contents of the display counter match the contents stored in the display counter address of the RAM 430. In this case, the content of the display counter at start is "0".

In step 7, the display code of the operation data memory is read out. By the system number 001 stored by the set system number in step 2 and the display counter 0, the data group of A001 indicating the system 001 in the embodiment shown in FIG. 7 is read. That is, the first display code "1010" and the display time data "0000" are read out, and each read data is stored in the display code address area and the display time data address area of the RAM 430, respectively. The first digit of the 4-digit display code 1010 is used for guidance when the vehicle arrives, and is the judgment data for preferential reading when the door signal is input through one of the input terminal groups 160. Is. At the starting station, the doors are open and passengers are given information such as "This bus is bound for Shin-Osaka." In steps 8 and 9, the display time is determined.

In step 8, the time signal set by the advance switch 130 and the delay switch 140 is read, and the start time stored in the RAM 430 is corrected. During the operation of the vehicle, the time switch input at the ON time of the advance switch 130 or the delay switch 140 during a predetermined monitoring time is the correction reference value of the advance or delay time of the subsequent vehicle operation. In step 9, the display time is determined. For example, in the display 2 of FIG. 4, “Next is Odawara” is displayed, but the display time “0115” of the display code “0031” in FIG. 8 is 1 hour 15 minutes after the vehicle starts. It will be displayed later.

If the display counter value at this time is "n", the nth display code becomes 0031 in FIG. The timer of the clock circuit 440 is set in step 5 by turning on the start switch 110 at the start of operation of the vehicle. The content of this timer and the correction data of the time stored in the RAM 430 are arithmetically processed and compared with the data at the display time "0115". When the data match, the operation of the next step 10 is performed. That is, if the time correction value is 15 minutes delayed by 0015, the display time data is “0115” ± correction value “0015” (delay +, advance −). In the case of delay correction, the data is displayed when the timer is 0130. Match.

In step 10, the display code memory 210 is read. Here, it is the lower three digits of the display code 0031 in FIG.
From 031 to the character code data “27,5 as shown in FIG.
“1,07, ×× …… ××” is stored in the character code area of RAM 430. Then, in step 11, the character code “27,51,07, ××” thus stored in the character code area of RAM 430 is stored.
The character pattern of "Next small ..." in the pattern memory 200 is read from "... XX", stored in the character pattern area of the RAM 430, and the display operation starts.

In step 12, the display operation is decided. That is, in step 12, the number of character constituents is calculated, and if the calculated number of character constituents is equal to or larger than the display capacity of the PDP 3, the flow display operation is determined, and if it is within the capacity, the fixed display operation is determined. . Next, the pattern data is read from the character pattern area of the RAM 430 and transferred to the input / output port I / O 453. In step 13, the display operation is performed. In step 14, it is judged whether the display is finished. The display is performed for a certain period of time, and the number of times the flow is displayed or a certain period of time during which the display is performed is determined based on the determination of the display operation, which is programmed and stored in the ROM 420.
When the display is completed, the displayed count value is incremented by 1 in step 16. Next, the operation returns to step 6, the preparation for reading the next display item is started, and the display is automatically started when the predetermined display interval is reached.

The display when the vehicle arrives at the station must be displayed immediately after the door is opened. This operation processing is performed by using the door open signal for processing the interrupt. That is, in step 17, it is also checked whether or not the display data of the rank indicated by the contents of the display counter value is the display code of the station. If the display data of the rank is different from the display code of the station, the counter value is sequentially incremented by +1. However, the display code at that time is read, and the count-up is performed until the station display code "1XXX" is read.

Also, if the display data of the ranking matches the display code of the station,
The display code of the operation data memory is read in step 18, and then the display code memory is read in step 10 for display. The end of the display is a step
This is done by checking the release of the door open signal at 14.

In addition, in the automatic readout display during vehicle operation, in order to prevent the arrival guide of the station from being displayed even if the vehicle has not arrived at the station when the display time of the station display code comes due to the setting error of the time switch. In the display code, "1xxxx"
It suffices to perform the display processing based on the judgment. Further, when it is desired to display the delay of the operating time of the vehicle, it is also possible to appropriately display "delayed by XX minutes" based on the input value of the time switch 120.

With the in-vehicle guidance display device of this invention, it is possible to perform a display in which the display contents for the passengers are selected corresponding to the time after the vehicle has started, and further the operation time is corrected and the corrected time is adjusted according to the corrected time. It is possible to display the corrected value of the operating time at the same time. Further, by correlating the reference time of the operating route of the vehicle with the distance of the operating route, various display operations can be performed according to the distance of the operating route.

As described in detail above, according to the present invention, it is possible to automatically display various types of guidance to passengers while the vehicle is in operation, and particularly for long-distance operation vehicles with long station distances. It is possible to provide an in-vehicle guidance display device capable of smoothly and appropriately performing guidance display for passengers in.
