Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operation control device for vehicles such as buses and trains, and in particular automates various controls necessary for the operation of vehicles, reduces the labor burden on drivers, and at the same time provides services to passengers. The present invention aims to provide an operation control device that can also improve the performance of vehicles.

<Background of the Invention> In recent years, it has become common for buses to be operated by one driver. Due to the one-man system, the driver must not only operate the wheels but also collect fares, which places a considerable burden on the driver.

On the other hand, from the passenger's perspective, improvements in bus service are desired. For example, at a bus stop, destination guidance is provided by voice to the outside of the vehicle immediately before the vehicle stops. The scheduled timetable shall be operated.

Respond by voice to the passenger's signal to descend. Under the present circumstances, it is impossible to make the driver bear the burden of meeting these demands, and it is rather desirable to reduce the driver's labor.

<Object of the Invention> The present invention aims to provide a vehicle operation control device that can improve service to passengers and reduce the driver's labor (3).

<Summary of the Invention> In this invention, control data that is critical to the operation of a vehicle is stored in a memory that can be read immediately, and the control data stored in this memory is sequentially read out in correspondence with the distance traveled by the vehicle, and the control data necessary for the route is read out sequentially in correspondence with the distance traveled by the vehicle. The aim is to configure the system so that all necessary controls can be performed automatically.

Therefore, in this invention, the control data necessary for the operation of the vehicle, the voice destination guidance broadcast, the voice response to the descent signal,
The data necessary for on-time operation is recorded in advance on a recording medium, such as the beginning of a magnetic tape, for broadcasting the stop names of the line, and these control data, destination guidance information, voice response information, etc. are converted into AD. Since the route is determined in advance by sequentially reading out from this memory, the left turn and right turn positions are also determined.

Therefore, for example, it is possible to control direction indicators, broadcast destination guidance etc. at necessary positions, and (4) also broadcast destination guidance to the outside of the vehicle when arriving at a stop. The system calculates the error value between the travel time and the actual travel time and displays it to notify the driver.

Embodiment\ FIG. 1 shows an embodiment of this invention. In the figure, 101 indicates an existing in-vehicle guidance broadcasting device. This in-car guidance broadcasting device 10
1 is composed of a tape player 102, an audio amplifier 103a, a tape stop signal amplifier 103b, a changeover switch 104, an in-vehicle speaker 05, and an external speaker 06.

The tape 107 used in the tape player 102 has broadcast contents 201a, 201b, 201C2, and
In addition to the track 202 on which the information such as . 108 indicates a tape drive control device;
When the tape automatic stop signal 203 is applied, the operation of stopping the running of the tape 1070 is performed.

Conventionally, a manual switch is connected to this tape drive control device 108, and the driver manually operates this manual switch to start the tape 107 and record the contents 201a, 201b, 201(!,・1
1 is played back and broadcast through the in-car speaker 105, and the next stop name is broadcast.

Furthermore, when the passenger door is opened, the selector switch 104 switches the amplifier 103a to the external speaker 106 in conjunction with the opening of the door.
At the same time, the tape player 102 is activated and the broadcast truck 202 sends a message such as ``Please take the numbered ticket.''

Please do not bring dangerous items. ” and other boarding information broadcasts.

Therefore, the driver is required to operate a switch that broadcasts the name of the next stop at an appropriate driving position after leaving the stop. Furthermore, even though the boarding guidance broadcast always has the same content, it must be played back from the tape 107, making the tape 107 necessary for a long time. Also, in the boarding information broadcast, there is a request to broadcast the destination name such as "This bus is on line 00", but if you broadcast this destination name, the tape length will become longer and longer. The tape will not be able to accommodate the required content in one line. For this reason, it has the disadvantage that the destination name cannot be broadcast.

As described above, conventionally, the workload of drivers is large and the improvement of service to passengers has been hindered.

In contrast, the present invention aims to provide a vehicle operation control system that can eliminate both of these obstacles, reduce the workload of the driver, and improve the service to passengers.

In FIG. 1, IO9 indicates this operation control device. This example shows a case where the operation control device is configured by a microcomputer. As is well known, the microcomputer includes a central processing unit (hereinafter referred to as CPU) 111,
The main components are a ROM 112 that stores programs that run this CPU III in a predetermined order, an immediately readable memory called RAMI 13 that stores sequentially imported data, and (7) an input port 114 that imports data. be.

In this invention, in addition to the main components of the microcomputer, a counter 115 is provided to add up the distance traveled, and the counter 115 is configured to count the travel pulses input from the travel pulse generator 116. Although a part of the RAMI 13 can actually be used as the counter 115, in order to simplify the explanation, the counter 115 will be provided separately and explained here.

The running pulse generator 116 may be one that generates pulses in conjunction with the rotation of a wheel or a four-wheel drive shaft, for example. For example, a turnout may be attached to a wire that transmits rotation to a speedometer, and a rotation sensor may be attached to this turnout. ) can be configured.

For example, assuming that 20 pulses are obtained during one rotation of the wheel, and the diameter of the wheel is 1 meter, the distance traveled can be detected with a resolution of about 16 centimeters per pulse. Therefore, by causing the counter 115 to integrate the travel pulses (8), the travel distance can be integrated with an accuracy of about 16 centimeters. The counter 115 transmits the accumulated mileage data to the CPU III through the input port 114.
The control information is fetched into the RAM 113 and compared with data stored in a register 118 to be described later, and when a match is detected, the control information is fetched from the RAM 113 into the register 117 to control various devices. .

It is assumed that the RAMI 13 stores in advance various control information necessary for the operation of the vehicle and distance information for executing the control information. This control information and distance information are recorded at the beginning of the in-vehicle guidance magnetic tape 107 used for that route, and when the train starts operating, this information is reproduced and transferred to the RAM 113 for use.

In addition to the above-mentioned control information and distance information, the information transferred from the magnetic tape 107 to the control device [109] also transfers audio information for destination guidance broadcasting and boarding guidance in the second invention of this application. For example, store information in audio-only RAMI.
19, and use this audio-dedicated RAM 11 as necessary.
9, the readout output is converted into an analog signal by a DA converter 121, the analog signal is amplified as an audio signal by an amplifier 103a, and the sound is emitted from a speaker 105 or 106. Indicates the case where

Control information, distance information, and audio information are stored on the magnetic tape 10, for example.
7 as a serial digital signal, which is reproduced and taken into the control device 109. For example, the serial digital signal is made up of 8 serial bits as one unit, and the control information and distance information are, for example, the first 3 bits of the 8 bits as control information 301 as shown in FIG.
Assume that the latter 5 bits are divided and used as distance information 302.

Further, all 8 bits of audio information are used as audio information, as shown in FIG. For example, voice information may be ``This car is 00.
It's a row. Please take a numbered ticket. " is sampled at a frequency of, for example, about 4 KHz, the sampled instantaneous analog value is AD converted, and the AD-converted parallel digital code is converted into a serial digital code and transferred to the magnetic track 202 of the magnetic tape 107. Just think about what you have recorded. Note that it is also possible to record an audio signal on the magnetic tape 107 and perform AD conversion when transferring it to the RAM 119.

Control information 301 and distance information 302 can be created, for example, as follows. First, a model driver drives the bus for each bus route, and collects the distance data between each stop.
Record data on the operation timing of each part. After leaving the first stop, the next stop name will be announced according to the route. Also, at what distance should a left or right turn signal be issued, how many meters before arriving at the next stop should a left turn signal be issued to enter a stop, and how far should the left turn signal be issued to enter the stop, and how far should the left turn signal be given to enter the stop, and how far should the left turn signal be given to enter the next stop? Distance values, cumulative values of pulse running pulses, etc. are recorded. The distance value between each stop shall be accumulated using each stop as a base point. If you do it like B, there will be a difference in the width of the car during the model drive and, for example, the tire pressure of another car.
Even if there is a difference in the travel distance values for each travel pulse, the error value based on that difference is reset each time the train arrives at each stop.
There is no accumulation, and the error value can be reduced.

The result of this model operation is converted into a digital code that carries control information and distance information, and the digital code is converted into a serial digital code and recorded on the magnetic tape 107.

FIG. 5 shows an example of the operation of each part in a model operation.

In FIG. 5, A indicates a running pulse. 501 indicates a departure stop, and 502 indicates an arrival stop. FIG. 5B shows an example of how a direction indicator is operated. After leaving stop 501, for example, at the 1000th driving pulse p+, operate the direction indicator to instruct a right turn, and then at the 1000th driving pulse P
1r:) Return the direction indication to the original state at the 200th pulse Pa, and then, for example, the 5000th running pulse P4 from the departure.
This shows a situation in which a left turn instruction is issued to enter the next stop 502, and the direction instruction is returned to the original direction when the vehicle stops. Figure 5C
indicates the status of next stop name broadcast operation. This example shows a situation where an operation is performed to broadcast the next stop name at the 1500th travel pulse P8 after leaving the stop 501.

If, for example, rl, O, and OJ are assigned as the right turn operation signals of the turn signal based on such a model driving example, rl, O, and OJ will be assigned as control signals, and a digital code representing the driving pulse P1 will be assigned. rO,0,1,O,OJ
is created and recorded on the magnetic tape 107 as a serial code.

The digital code ro, 0, 1 created as this distance information
,0. For example, if OJ uses the upper 5 bits of a hexadecimal counter, this digital code IO, 0, 1,
0 and OJ are 1024 pulses in decimal notation, but the 24 pulses are ignored as a difference. If the upper 5 bits of the hexadecimal counter are used as distance information in this way, a maximum of 7936 travel pulses can be counted, and the minimum resolution is the lowest pitch every time 256 travel pulses are input. ) The resolution is such that H logic stands on B4. Assuming that the traveling pulse generator 116 has the above-mentioned conditions, that is, the diameter of the wheel is 1 meter, and 20 pulses are generated per rotation of the wheel, the minimum resolution is approximately 41 meters. Therefore, an error of 41 meters occurs, but even if the timing of various operations during driving is shifted by about 40 meters, the error does not become large. Also, the maximum distance that can be expressed under these conditions is approximately 1,270 meters. The average distance between bus stops in urban areas is approximately 500 meters, so being able to count a distance of 1270 meters is sufficiently practical for bus routes in urban areas. In addition, if there is a section where the distance between bus stops exceeds 1270 meters,
It is sufficient to increase the number of stages of the counter that counts the running pulses during the model driving, and also to increase the number of bits of the digital code used as distance information.

At the end of a right turn, a digital code, for example rO, O, OJ, is created to return the control information 301 to its original state, and this digital code ro, 0, OJ and distance information representing the 1200th running pulse are created, ``t, o, 1.o''. .

0". This digital code is 1 in decimal
024+256=1280 pulses, but 80 pulses are considered as an error.

For example, rO is used as an operation signal for in-car guidance announcement based on the next stop
,0,IJ. According to the model driving, this in-vehicle guidance broadcast is performed at the 1500th driving pulse, so the distance information is rO, 1, 1, 0, which is close to 1500.
0J (1536 in decimal) is generated, converted to a serial code, and recorded on a magnetic tape.

For example, a right turn operation is assigned a digital code rO, 1, OJ. During a right turn operation, the driving pulse is the 4000th, so the digital code r has a value close to 4000.
Create o, o, o, o, I J (representing 4096 pulses in decimal notation), and write this as a serial code on magnetic tape 1.
Recorded on 07.

The control information 301 described above includes distance information when stopping at the next stop during model driving, as well as reset information for resetting the counter 115, for example, II, 1, I.
Insert J. This reset information is used to automatically reset the counter 115 when the vehicle passes through a bus stop without stopping.

In this way, the distance information close to the operation timing of each model drive is digitally encoded, converted into a serial digital signal with each control information, and sequentially recorded on the magnetic tape 107.

The control information 301 and distance information 302 recorded on the magnetic tape 107 are reproduced at the start of operation, and the input boat 11
Memory that can be read instantly through 4? ,9RAM1
Transferred to 13. The information 301 and 302 may be transferred at once for all sections of the path route, or the information for the next section may be transferred after each section where the name of each stop is recorded. Control information and distance information may also be recorded. Here, we will explain a case where all the control information 301 and distance information 302 necessary for the route are transferred at once at the start of operation, and all the information is loaded into the RAM 113.

The information recorded on the tape 107 is sequentially loaded into the RAMI 13 from the first address to the next address. The captured control information 301 and distance information 302 are sequentially fetched into registers 117 and 118 in accordance with the address order. Control information 301 is stored in the block register 117.
is taken out, and distance information is also taken out to the register 118. Here, the count value of the counter 115 is
When the distance information 302 stored in the register 117 matches the distance information 302 stored in the register 117, the control information 301 stored in the register 117 is
The stone is decoded by 11, and each device is controlled according to the decoding results.

In FIG. 1, 122 indicates a direction indicator, and register 1
If the information stored in 17 is direction instruction information, the CPU 11 outputs a signal specifying the interface 123 to control the direction indicator 122, and controls the right turn or left turn instruction at a predetermined driving position. Let's do it.

Distance information stored in register 118 and counter 115
When the count values match, the successive addresses in the RAMI 13 are incremented by one, and the control information 301 and distance information 302 of the next address are read out, the control information 301 is stored in the register 117, and the distance information is stored in the register 118, respectively. Stored.

Further, 124 indicates an interface for starting control of the tape player 102. This interface 124 stores control information such as rO, O, IJ for in-vehicle guidance broadcasting in the register 117, and then displays the counter 11
5 and the distance information in the register 118, a start command is given to the tape drive control circuit 108, and the playback device 10
2 and broadcasts the in-car guidance for the next stop.

Reference numeral 125 indicates an interface for controlling the changeover switch 104. This interface 125 operates to select the speaker 105 of the switch 104 when the tape player 102 is in operation.

Accumulate the distance traveled by the Yoshibus above, and use the accumulated value and RA.
It will be understood that when the values of the distance information 302 stored in the MI 13 match, the multi-directional indicator 122 and the tape player 102 are automatically controlled by the control information 301.

Description of Immediately Readable Audio Memory 119 Next, the audio signal reproduced from the audio RAM 119 will be described. As described above, this audio RAMI 19 stores audio information that repeatedly broadcasts the same content, such as destination guidance. For example, this audio information may include messages such as ``Please take a numbered ticket,'' ``Please do not bring dangerous goods,'' ``Next stop,'' and ``The train is departing.'' in addition to the destination announcement. The audio is AD-converted, the AD-converted value is serially digitally encoded, and recorded at the beginning of the magnetic tape 107, reproduced only once at the start of operation, transferred to the audio RAM 119, and stored in the audio RAM 119. During this storage, the serial digital code is converted into a parallel digital code and stored in each address of the RAM 119 as a parallel digital code.

By adopting such a method of transferring voice information to the RAMI 19 and a method of recording the RAMI 19, it is possible to manufacture voice synthesis ICs for each line at a lower cost.

The audio information taken into the RAMI 19 is stored in a designated storage area for each word and phrase, and the storage area is designated and read out as needed.

For example, when the push button 126 for alighting signal is operated by a passenger while driving, the CPU 111 enters an interrupt operation and stores the words "Next stop" stored in the voice RAMI 19 during the interrupt. The obtained region is extracted, the signal is converted into DA, and is supplied to the amplifier 103a through the filter 127.

On the other hand, it is desirable to broadcast destination guidance to the outside of the vehicle immediately before the vehicle stops at the stop. For this reason, the fifth
The left turn operation position pulse P4 representing entering the stop explained in the figure is detected, and the direction indicator 122 is automatically controlled to the left turn display state at the position of this distance, and after the position of P4 is detected, for example, the brake pedal 128 The vehicle speed detection program is executed when the two conditions match. This vehicle speed detection program detects when the number of travel pulses input per unit time becomes less than or equal to a predetermined number, and performs an operation to detect the state immediately before stopping at a stop.

To do this, for example, the number of increases in the count value of the counter 115 may be monitored every unit time, and it may be detected that the number of increases has become equal to or less than a predetermined value.

When the vehicle speed detection program detects the state immediately before stopping at a stop, the CPU 119 reads the audio RAMI 1.
The storage area containing the destination guidance broadcast of No. 9 is read out. At the same time, the interface 125 controls the switch 104 to select the external speaker 106.

In this way, the vehicle speed detection program detects the state immediately before the vehicle stops at the bus stop, and broadcasts the destination to the outside of the vehicle. Therefore, a person waiting for a bus at a bus stop can see where the bus is going even if he or she overlooks the bus's destination display. This is especially convenient for visually impaired people.

When the bus stops at a stop and the door is opened, the door signal will be used to announce the destination, as well as memorize phrases such as ``Please take a numbered ticket.'' and ``Please do not bring dangerous goods.'' The CPU III operates so that the areas thus read out are also subject to reading, and these boarding guides are broadcast together with the destination guide broadcast. Furthermore, when the vehicle speed becomes completely zero, CPUI 1
When it is detected that the 1U bus has stopped, the counter 115 is reset, and the first information required for the next section is read from the subsequent address in the RAM 113.

When the door is closed and the first running pulse is input to the counter 115, the CPU III detects that the bus has started moving, and reads out the area in the audio RAM 119 where the phrase "The train is leaving" is stored in the CPU 111. This action is performed, and the message ``The train is departing'' is broadcast to both the inside and outside of the car to warn passengers and those outside the car.

The audio information 40 imported into the audio RAM 119 in this way
1, the passenger's descent signal operation device reads out the required storage area as necessary by the vehicle speed detection means, and performs a stop release notification or a destination guidance announcement. These broadcasts are unprecedented broadcasting services and can improve services for passengers.

<Explanation when passing a bus stop> If there are no passengers to get off at the next stop and no one is waiting at the stop, the bus will pass without stopping at that stop. At the time of passing the stop, the address is updated and stored in the RAM by detecting a match with the previous distance information.
113 to reset information 11,1. Distance information representing the IJ and its stop position is read out, and this is stored in register 11.
7 and 118. Therefore, the distance information 302 stored in the register 118 and the value of the counter 115 match before and after passing the stop (this can be considered to be a slight error from the time of model driving). Reset information rl stored in 117,
1, IJ is decoded by CPU III and counter 1
15 is reset.

Therefore, the counter 115 counts the travel pulses again from the initial value, and performs various controls according to the control information 301 at each travel distance position set in the next section.

Note that if the vehicle passes through a stop, the vehicle speed detection program will not be executed, and the CPU
11 does not read out the audio RAM 119 and perform boarding guidance and departure guidance in this state.

<Other Control Equipment> The basic configuration and operation and effects of the present invention will be understood from the above. In this embodiment, a case is shown in which the system is configured to perform various controls necessary for the operation of the bus.

One way is to control an indicator that alerts following vehicles that you are entering a stop. In FIG. 1, 129 indicates a display mounted at the rear of the bus.

For example, this has a built-in illumination light, and when this illumination light is turned on, it displays to following cars the message ``Entering the bus stop.'' Notifying them that the bus is entering the bus stop. This display 1
Conventionally, the 29 is operated in conjunction with a left turn direction indicator, but this has the disadvantage that whenever a left turn instruction is issued, a message saying "Enter the stop" is displayed.

However, if the present invention is applied, the display 129 can be operated only when entering a stop by storing in advance the distance position at which the display 129 is to be operated in the RAMI 13. 131 is the display 129 (25)
The interface for operating c77 is shown.

Explanation regarding on-time operation indicator> 132 indicates an on-time operation indicator. When the train arrives at the next stop, this display shows whether the actual schedule matches the scheduled timetable, or whether it is ahead or behind. The time required for each section of the scheduled timetable is stored in the RAM 113 together with the above-mentioned various data, and a clock means 133 is also provided. For example, this timer 133 is reset each time a train departs from a stop and measures the passage of time from the initial value, and when it arrives at the next stop, the timer value of this timer 133 and the standard stop time stored in the RAM 113 are calculated. The comparison is made and the delay and advance are displayed on the display 132. 134 is an interface for connecting the display device 132 to the CPU 11.

<Explanation regarding the control of the destination guidance display> Conventionally, the destination guidance display has been manually operated by the driver so that the information corresponding to the route being operated is displayed. (26) can also be automated.

That is, control information regarding the destination guidance display is recorded on the magnetic tape 107, this control information is transferred to the RAM 113, destination guidance display data is further transferred to the register 135, and based on the data value stored in this register, The destination guidance display 136 is controlled.

Destination guidance display 136 can be of various types. For example, in the case of a conventional method in which subtitles are moved for display, a digital code assigned to each destination is stored in the register 135, and the digital code and the display 1
The movement of the subtitles may be controlled until they match with the digital code transmitted from the subtitle display position detecting means provided at 36, and the movement of the subtitles may be stopped at the time they match.

In addition, as another new type of display device, for example, a large number of liquid crystal cells or other dot display elements are attached to the display surface, and the dot display elements selectively display dots, and the destination name is displayed on the dot display. You can also do that. In this case, the static table star 135 has the same number of capacitances as the number of dot display elements of the display 136, and this register 13
All of the amount of data necessary for display is stored in the register 135, and the output of the register 135 controls the dot display element.

In the case of dynamic display, for example, the RAM 113 stores all the data necessary for displaying the destination, and the register 135 has a capacity for one line in the horizontal direction of the display 136, for example, and the data is stored for each line. It is only necessary to transfer the data and display the dots on the display in a time-divided manner.

<Proximity detector control> When the bus departs or turns left, the driver must check whether there are people or other vehicles on the left side of the bus. It is conceivable to operate the proximity detector 137 using a high-frequency oscillator in such cases to prevent failures.

Therefore, it is possible to configure the proximity detector 137 to be automatically operated by the CPU III when the left turn indicator is activated and when viewing the table, thereby detecting obstacles in advance. Note that 138 connects this proximity detector 137 to the CPU 11
Indicates an interface for connecting to.

<Effects of the Invention> As explained above, according to the present invention, various operations performed by a bus driver can be controlled in a predetermined order in conjunction with the travel distance. Therefore, the bus driver can concentrate only on driving while the bus is running, thereby preventing accidents and reducing labor.

However, when the audio RAM 119 is added to the control, various guidance can be given to the passengers by voice. Therefore, it is possible to realize an unprecedented service in which destination guidance can be provided by voice, and its effects are extremely large in practical use.

Furthermore, in this invention, the integrated value of the counter 115 is reset to zero each time the vehicle stops or passes through a stop, so the number of pulses generated by the travel pulse generator 116 for the distance traveled varies depending on the vehicle. Even if there is, the error in the control position relative to the traveling distance will not be added up. Therefore, the error in the control position for each section can be reduced.

In the above description, a bus was used as an example of a vehicle.
It is easy to understand that this invention can also be applied to other vehicles such as trains.
