Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operation status display device for displaying whether or not a vehicle is operating as scheduled in a public transportation vehicle such as a bus.

Conventionally, in the operation of shared vehicles, so-called buses, the driver receives an operation schedule card containing the schedule for that day, reads the card, and operates the bus according to the contents of the card. In other words, before starting the operation, set the destination display, fare display, etc. in accordance with the service system you are about to operate, confirm the service start time, start the service, and check each stop during the operation. The train operated in such a way that the passing time coincided with the scheduled passing time for that stop.

However, checking the schedule every time during a trip places a burden on the driver and is undesirable from the standpoint of driving safety, so it is not often practiced in practice. On the other hand, when looking at passengers, it would be extremely convenient if the passengers were informed of the situation, such as when the train is significantly behind schedule. From this point of view, Japanese Unexamined Patent Application Publication No. 1973-
Publication No. 86630 proposes recording the scheduled time of each stop on a broadcast tape, reading out the scheduled time of each stop, comparing it with the current time, and detecting and displaying delays.

However, in this case, it is necessary to store the scheduled time on a broadcasting tape in addition to the operation card on which the operation schedule is written, and although it is necessary to use the broadcasting tape that corresponds to the operation card, there is a risk of using it incorrectly. Furthermore, there is a risk that there will be a discrepancy between the reading of the scheduled time and the stop. Further, this conventional technology merely detects delays and advances, and there is no idea of effectively utilizing the detected delays and advances for timetable revisions, traffic management, etc.

The purpose of this invention is to make the driver easily aware of the operation status, so that it is relatively easy to make the driver make efforts to follow the scheduled operation, and to notify passengers of the delay situation as necessary. To provide an operation status display device that can be used to display data, which can prevent accidental use, and which can also obtain data for timetable corrections and the like.

According to the present invention, an operation card is used in which at least the passing reference time for the main stop is displayed, and the passing stop signal and the scheduled passing reference time are stored in a readable manner. Each time a stop is passed, a step signal is given to generate a stop signal indicating the stop passed, and each time the stop signal is generated, the operation card mentioned above is read out and the corresponding operation card is read out. Read the estimated passing time for the stop signal. At the same time, the current time signal at that time is read from the time signal generator, the scheduled passage time is compared with the current time signal, and the lead/lag and the amount thereof are detected from the difference and the lead/lag is displayed on the display section.

At this time, it not only simply displays the lead or lag, but also displays quantitatively, that is, numerically, how far ahead or how far behind the vehicle is behind, if necessary. Such a display can be displayed not only to the driver but also to passengers if necessary. In this way, by using this operation status display device, the driver does not have to look at the information on the operation card and calculate in his head the difference between the current time and the scheduled passing time, and the driver can check the delay or advance status. Since it is displayed automatically, it is possible to know whether or not the service is operating normally just by looking at the display, and it is possible to make efforts to restore the service to a normal state. It is also possible to provide services to passengers by displaying the delay status to them.

Furthermore, a storage section is installed in the operation card to record the time at which each stop was passed, and after the operation is completed, the actual operation status and the standard operation status are compared, and this information is used to create a more preferable operation schedule. It can also be used for labor management of drivers. It is also possible to record the operating system etc. on the operating card, read out the operating system prior to operation, and automatically switch the destination display, fare display, etc. based on the readout output.

Next, an embodiment of the driving status display device according to the present invention will be described with reference to the drawings. First, an example of the operation card used in the operation status display device of the present invention is shown in FIG. For example, the operation card 11 made of a sheet of relatively thick paper or synthetic resin material has the operation date, vehicle number, driver's name, and driver code written on the top of one side of the card, similar to conventional operation cards. , followed by the number or name indicating the first service system, followed by the numbers for the destination display setting and fare display setting, and for this, the service start time and the main stop of the service system. For example, the stop number 12 and the standard scheduled time 13 for passing through that stop number are listed in order, followed by the set numbers of the second operating system, destination display, fare display, and required time. Each stop and its scheduled time of passage are listed.

Further, the operation card 11 stores each content written on the operation card so that it can be read out. For example, in this example card 1
A magnetic stripe 14 is formed along the longitudinal direction on one side of the card, and the same content as that written on the travel card is stored on the magnetic stripe 14. Regarding each stop number and scheduled passing time, the signal indicating the stop and the scheduled passing time are stored not only for the main stops but also for all the stops.

That is, as shown in FIG. 2, the recorded contents of the read stripe 14 include, for example, a code 1 indicating the start of recording is recorded at the beginning of the stripe, followed by the operation date, then the vehicle number, and then the driver code. , after which the delimiter 2 is stored,
Subsequently, the first operation instruction data 3 is stored,
As well as the previous date, vehicle number, etc., the service system, destination number, and fare display setting number are stored in the order they are written on the service card, and then the separator code 2 is stored, and the next stop number and its schedule are stored. The time signal is stored alternately. In this case, the estimated passage times are stored not only for the main stops, but also possibly for more or all stops. The storage for the next operation instruction data 4 is delimiter code 2.
The information is recorded in the same manner as the operation instruction data 3. An end code 5 is stored at the end of all recordings.

Also, in this example, this read stripe 1
A writing magnetic stripe 15 is formed in parallel with 4, and the passing time corresponding to each stop is recorded on this magnetic stripe 15.

FIG. 3 shows an embodiment of the operation status display device according to the present invention, and in the present invention, for example, a card reader that can read the signal indicating the stop and the scheduled passing time from the operation card 11 as shown in FIG. 1 is used. A section 16 is provided. A step signal is also provided each time the bus passes each stop. That is, each time the vehicle passes a stop, the step signal generator 17 generates a step signal. This stepping signal is generated by a switch each time the driver passes a stop, or the stepping signal is automatically generated when the driver starts running from a stop and reaches a predetermined speed or higher. Further, a time signal indicating the current time is supplied from a time signal generator 18.

Every time a step signal is obtained from the step signal generator 17, a stop signal indicating the stop that has just been passed is generated. In this example, a so-called microcomputer is used as the control unit 19 for various controls, and the microcomputer 19 has a central processing unit, so-called CPU 22, and a program for processing stored on its bus 21. Read-only program memory 23
A read/write memory 24 for temporarily storing data necessary for various processes and for reading the data is connected. Furthermore, an input port 25 for taking in data and an output port 26 for outputting data.
are connected to the bus 21, respectively. Control part 1
9 monitors the step signal from the step signal generator 17, and when this occurs, the input port 25
For example, the memory 24
A part of the counter 27 is used as a counter 27 for generating a stop signal, and the contents of the counter 27 are controlled to be incremented. Therefore, each time an increment signal is generated, the contents of the counter 27 increments. The counter 27 is reset at the start of operation of the service system, and therefore, each time a stop is passed, the stop number sequentially assigned to the stop of the service system is obtained from the counter 27. In this way, the stop signal is obtained from the counter 27.

Every time a step signal is obtained, the counter 27 at that time
The driver learns the passing stop from the stop signal from the train and reads out the scheduled passing time signal for the corresponding stop number from the operation card 11. Further, the current time at that time is detected from the time signal generator 18, and the difference between the current time and the scheduled passage time signal is taken to detect whether the vehicle is ahead or behind, and the detection result is displayed on the display section. .

When using a travel card as shown in FIG. 1, the card reader 16
Reading the operating card 11 through the stripe 14
The data stored in advance is read through the input port 25 and stored in the area 28 of the memory 24 in advance. When a step signal is generated due to the start of operation, the scheduled passage time signal corresponding to that signal in the storage area 28 is read out based on the stop signal of the counter 27 obtained based on this signal, and the scheduled passage time signal corresponding to that signal is read out from the time signal generator 18. The control unit 19 calculates the difference between the obtained current time signal and calculates the difference in minutes, for example, if the current time is ahead of the scheduled time and the bus is running late. It is displayed on the display section 31. A display indicating that there is a further delay is displayed on the display unit 32. If the time is ahead of the scheduled time, this fact is displayed on the lead/lag display section 32 and the amount of advance is displayed on the display section 31.

As mentioned above, the operation card 11 records not only the scheduled time of passing at a stop but also various other data, and these data are also displayed as necessary. That is, when the travel card is first attached to the reading section 16, all the data is read and the travel system number, destination display setting number, fare display setting number, etc. are displayed on the display section 33. Further, the current time is displayed on the display section 34, and the service start time is displayed on the display section 35. Each time you pass a stop, a code indicating the stop you passed, such as a number, is displayed on the display section 36.
The scheduled passing time is displayed on the display section 37.

Such displays are displayed on a display panel 38 as shown in FIG. 4, for example, at a position where the driver can easily read them while sitting in the driver's seat.

As mentioned above, delay display can also be performed for passengers, for example, in which case the display section 38 for passengers is connected in parallel with the display section 31 that displays the amount of advance or delay, and Display section 3 only if
A display is made to appear at 8. This display section 3
8, for example, as shown in Figure 5, only the display indicating the amount of delay appears as a number, and the words ``Currently ahead of schedule'' and ``The train is running a minute behind schedule'' are permanently displayed before and after it. be made into

The destination display setting number is displayed, and the setting number is given to the destination display 41 to automatically set the destination display, and the fare display setting number is similarly given to the fare display 42 to be used for that service system. Set so that the corresponding fare display appears. In the past, settings for the destination display 41 and fare display 42 were automatically set by giving a number or code to these displays; It can be done by

Furthermore, the service start time stored in the service card and the current time are constantly checked, and when the service start time or a little before the service start time, the display lamp 43 of the display panel 38 blinks to indicate that the service start time has arrived. A buzzer 44 is displayed to the driver to notify the driver.
It is also possible to make an audible notification by making a sound. The lead/lag display section 32 may display a lamp 32a or 32b depending on the lead or lag.

Furthermore, as mentioned earlier, the write stripe 1
5, an operation card is used in which data can be written to the operation card 11. For example, in the previous example, each time a step signal is obtained, the current stop passing time is recorded in correspondence with the stop signal, for example. It is written into area 28 of memory 24 . In addition, the reading section 16 is configured to be writable, and the operation card 1 is read after all operations are completed.
1 from the reading section 16, the actual passing time of each stop stored in the storage area 28 can be written on the writing stripe 15 of the operation card.

In some cases, a surveillance camera is installed to monitor the rear of the bus, and the images taken by the camera are displayed on a monitor television for the driver to view. It is also possible to cause the monitor television to display a display as shown in FIG. For example, as shown in FIG. 6, which shows a part of the configuration shown in FIG.
The refresh memory 46 is read out in synchronization with the television monitor 47 and supplied to the pattern generator 48, and the pattern generated thereby is supplied to the television monitor 47 and displayed. The monitor television 47 can monitor the outside of the bus by receiving a signal from a monitoring television camera 49 on the outside of the bus, particularly at the rear, through a switch 51. When displaying the operation status, switch 51 is connected to pattern generator 48.
Switch to the side to display the operation status on monitor TV 47
to be displayed.

As the travel card 11, not only a magnetic medium can be used, but also a semiconductor memory, a magnetic bubble, etc. can be used. For example, as shown in FIG. 7, a thin case 53 is provided as the operation card 11,
On one side of this case 53, various information such as the date of operation and the vehicle number are written in the same way as described in connection with FIG. A storage element 55 such as a memory or a magnetic bubble is mounted.
The memory element 55 is connected to a multi-connector 56 provided at one end of the case 53 through wiring on the board 54. By attaching the multi-connector 56 to the reading unit shown in FIG. 3 that corresponds to this operation card, the contents can be read or written as necessary. The memory element 55 stores the same contents as described in connection with FIG. 2, and can also write the same contents. When such an element is used, it is also possible to read only the necessary part from the operation card 11 each time without providing the storage area 28 in FIG. 2, and to write the current time each time the train passes a stop. can.

As described above, according to the operation status display device of the present invention, the operation status, that is, the delay or advance status with respect to the scheduled timetable, is displayed, and the driver can check the current stop and its scheduled passing time on the operation card. There is no need to perform operations such as reading from the current time and comparing it with the current time, and by simply looking at the display, you can immediately know how far behind or slow the operating status is, and the train will operate according to the fixed timetable as much as possible. It's easy to make an effort. Furthermore, if necessary, it is possible to provide services to passengers by displaying the status of service delays to the passengers.

As explained above, data for operation-related equipment is stored in the operation card, and by reading this data and providing it to the corresponding operation-related equipment, settings such as destination display and fare display are automatically performed. This can reduce the driver's effort. By giving a warning about the departure time, it becomes possible to operate the train accurately, which reduces the workload of the driver, reduces the burden on him, and reduces the chances of mistakes.

Furthermore, since the system is configured to store the actual operating conditions, it is possible to read the memory later at the center, analyze the delay state, and revise the operating schedule to suit the operating system. Conventionally, it has been difficult for drivers to record their own driving conditions, and it has been almost impossible to record information during driving. However, by recording such operation status, it becomes possible to reorganize the operation schedule to be more appropriate for each point on the route, and it can also be used for driver labor management and other purposes. . In the previous embodiment, various functions were added, but at least it is sufficient to display the delay or advance of the scheduled operation.
