[0026]

The operation of the route data management apparatus according to the present invention having the above-described configuration will be described below. According to the first configuration of the present invention, when route data including route data including route facility change completion date and time is input from the input operation unit, the route data is filed in the route data file. In this case, only the changed route data is input in the normal operation except when the route data is first created, and the unchanged route data is generated from the previous file. The changed route data accompanied by the route facility change completion date and time includes data for which the route facility change has already been completed and which has not been changed to the non-volatile memory of the on-board device (for example, a vehicle that has not started operation) and There are both plans to change the line facilities, but there are both.

The filed route data is sent to the valid route data extracting means. In the effective route data extraction means,
A certain reference time point is set, and the change route data in which the route equipment change completion date and time is earlier than the reference time point out of the changed route data, that is, the changed route data in which the equipment change has already been completed when viewed at the reference time point, is extracted. Is output as valid route data together with the route data of a place where there is no change.

Here, the meaning of "valid" means that the change work has been completed and the route data should be changed at the reference time. The effective route data thus obtained is sent to a medium writing means, where it is written to a portable data medium. As the data medium, for example, an IC card, a magnetic card, a magnetic disk, or an optical disk is used. The clerk carries the data medium on which the effective route data is written in the vehicle, and inserts or fits the data medium into the reading means of the on-board device. Then, the reading means automatically reads the effective route data.

The on-vehicle data updating means updates the route data stored in the nonvolatile memory with the read data. In the case of the initial start-up in which nothing is stored in the nonvolatile memory, the first write is performed instead of the update. The traveling position detecting means detects a current traveling position by receiving a signal from a ground member disposed along the route, and sends the position information to the route data output means. The route data output means outputs the route data corresponding to the detected position to the vehicle operation control means from the route data stored in the nonvolatile memory.

As described above, according to the route data management means of the present invention, when the route equipment is changed or scheduled to be changed, the change date and time or the scheduled change completion date and time is dealt with. After inputting the changed route data, the reference time point of the effective route data extraction means is set, the data is automatically written to the data medium, and the data medium is automatically read by the reading means on the vehicle. Since the route data can be updated, the data can be updated quickly and surely according to each time. The second configuration, the third configuration, and the fourth configuration are examples in which the reference time point of the effective route data extraction unit is specifically set in the first configuration.

The fifth configuration is a further improvement of the invention of the first configuration. In the first configuration, when the data medium on which the effective route data is written is inserted into the reading means on the vehicle, all the data written on the data medium is updated in the nonvolatile memory. That is, not only the changed portion but also the unchanged portion are updated with the same data. This means that unnecessary update is performed for a part that has not been changed, and unnecessary update time is wasted. The fifth configuration is for eliminating this waste.

In this configuration, a temporary storage memory for temporarily storing only the changed route data is provided in the on-board device in addition to the nonvolatile memory of the first configuration. The route data of the changed part is stored in the temporary storage memory, and the route data corresponding to the traveling position of the vehicle is stored in the temporary storage memory when the data is output to the vehicle operation control means. When the data is stored in the temporary storage memory, the data is output from the non-volatile memory.

In this way, by storing or updating only the changed route data in the temporary storage memory and then outputting it, all data in the non-volatile memory is updated every time there is a change. Eliminates the need. Then, when the changed portions are accumulated to a certain extent, all the changed portions are collectively updated in the non-volatile memory, so that the number of all data updates can be reduced as much as possible. Waste time can be eliminated.

In correspondence with the above configuration of the on-vehicle device, the ground device is provided with a modified route data file in addition to the route data file of the first configuration, and the route data file is first stored in the non-volatile memory on the vehicle. Or file route data for updating data in the non-volatile memory. Then, in the changed route data file, the changed route data including only the changed data accompanied by the route facility change completion date and time information is filed. This changed route data is
The first configuration is that, even though the change of the route equipment has already been completed, there are both the change of the temporary storage memory of the on-board device that has not been completed and the change of the route equipment to be performed from now on. Same as in the case.

When the changed route data is input from the input operation unit, the data is filed in the changed route data file, and the data of the portion corresponding to the change in the route data file is also updated. That is, the route data file always contains the latest version of the route data.

The changed route data stored in the changed route data file is sent to the valid changed route data extracting means. In the valid change route data extracting means, a certain reference time is set, and the change route data whose route equipment change completion date and time is earlier than the reference time, that is, the change whose facility change has already been completed when viewed at the reference time. Route data is extracted and output as valid change route data. Here, the meaning of “valid” means that the change work has been completed when viewed at the reference time point and the route data should be changed, as in the case of the first configuration.

The valid change route data thus obtained is sent to the medium writing means, where it is written to a portable data medium. As a data medium, for example, an IC card,
A magnetic card, a magnetic disk, or an optical disk is used. The data medium on which the valid change route data is written is carried by the attendant to the vehicle, and the data is automatically read when inserted or fitted into the reading means of the on-board device.

When the valid change route data is read, the updating means stores or updates the valid change route data in the temporary storage memory. In outputting the route data to the vehicle operation control means, when the route data output means receives the current travel position information of the vehicle from the travel position detection means, the route data corresponding to the travel position is stored in the temporary storage memory. If it is, the output is made from the temporary storage memory, and if it is not stored in the temporary storage memory, it is made to output from the non-volatile memory. That is, unchanged data is output from the non-volatile memory, and changed data is output from the temporary storage memory.

If the change route data in the temporary storage memory increases while the above operation is continued, all the stored data is updated every time there is a change, as in the first configuration. Therefore, the stored data in the non-volatile memory is changed and the route data is fetched at predetermined appropriate periods or when the amount of data in the temporary storage memory reaches the predetermined amount of data. Need to be updated.

For this reason, the route data file of the ground apparatus includes the latest route data stored in the non-volatile memory, and the data of the corresponding portion is updated every time the changed route data is input thereafter. Version route data is filed. The route data of the route data file is sent to the medium writing means, where it is written to a portable data medium. This data medium is read when an attendant carries the vehicle and inserts it into reading means on the vehicle, and the updating means updates the route data in the nonvolatile memory to the latest version. At this time, the changed route data file of the ground device and the temporary storage memory of the on-board device are temporarily emptied, and the changed route data input after the update is filed or stored.

The updating of the non-volatile memory is performed every predetermined appropriate period or every time the amount of data stored in the temporary storage memory reaches the predetermined amount of data. Waste time can be greatly reduced. The sixth configuration, the seventh configuration, and the eighth configuration include:
This is an example in which the reference time point of the effective change route data extracting means is specifically set in the fifth configuration.

The ninth configuration is such that the ground equipment of the first configuration is combined with a control center and an operation section or an operation station (hereinafter referred to as an operation section).
And a signal transmission circuit, a transmission means, and a reception means required by the divided arrangement. The on-board device is the same as in the first configuration. When the management range is relatively narrow, the effect of management can be sufficiently exhibited even if the ground equipment is arranged collectively as in the first configuration. However, when the management range is wide, change of route equipment and completion of construction Even if the date and time and the contents of the change of the route data are centrally managed and input in one place, it is better to arrange the means for writing to the data medium in each of the divided areas (driving wards or driving stations) to carry the data medium with the vehicle. This is convenient, and the reference time point for extracting the changed route data can be selected according to the situation of each district.

In this configuration, an input operation unit and a route data file are provided in the management center, and a route data file, an effective route data extracting means, and a medium writing means are provided for each driving section within the management range. Further, a transmission circuit connecting the management center and the operation section, a transmission means for transmitting the data of the route data file to the operation section via the transmission circuit to the management center, and a transmission circuit from the management center to the operation section. Receiving devices for receiving the route data transmitted via the transmission circuit are provided respectively. Then, one or a plurality of driving sections are set for one management center. The functions of the constituent units of the ground apparatus and the on-board device excluding the transmission unit, the transmission circuit, and the reception unit are the same as those in the first configuration. The tenth, eleventh, and twelfth configurations are examples in which the reference time point of the effective route data extraction unit is specifically set in the ninth configuration.

The thirteenth configuration is a case in which the ground equipment of the fifth configuration is separately provided for a management center and an operation section for the same purpose as the ninth configuration. That is, the management center is provided with an input operation unit, a route data file, a changed route data file, and a transmitting unit, and the driving section is provided with a receiving unit, a route data file, a changed route data file,
Effective change route data extracting means and medium writing means are provided, and the management center and the operation section are connected by a transmission circuit. It is similar to the ninth configuration that there are a plurality of driving sections. The functions of the transmitting means, the transmission circuit, and the receiving means are the same as those in the ninth configuration, and the functions of the other components are the same as those in the fifth configuration. Also,
The on-board device is the same as that of the fifth configuration. The fourteenth configuration, the fifteenth configuration, and the sixteenth configuration are examples in which the reference time point of the effective change route data extraction unit is specifically set in the thirteenth configuration.

The seventeenth configuration is an example of functional improvement of the fifth configuration, wherein the valid change route data extracting means detects two or all of the current time, the schedule operation start time of the day, and the route facility change location passing time. It is possible to create a data medium on which valid change route data with the time as a reference time is written.

On the other hand, in the on-vehicle apparatus, the temporary storage memory has a storage area that can be stored and updated for each reference time, and the updating means has the identification means for the reference time and is read by the reading means. The reference time point of the valid change route data is identified and stored in the corresponding storage area. The route data output means receives a reference time designation command from the ground,
Route data corresponding to the traveling position of the vehicle is output from a temporary storage memory area in which the valid change route data at the designated reference time is stored.

According to such an operation, the case where the change work of the route equipment has not been completed after the change completion date and time initially input or, conversely, the change work has been completed earlier than the change completion date and time initially input. In such a case, it is possible to select and output the effective change route data extracted at the reference time point suitable for the construction completion status. For example, when the valid change route data with the reference time as the passage time of the route equipment change point was to be applied, if the construction scheduled to be completed before that time does not complete as scheduled, Since the changed route data corresponding to the changed portion should not be applied, it is necessary to shift the reference time to a time immediately before the passing time, for example, to the timetable for starting the bus schedule. In such a case, the purpose is achieved by switching the storage area of the temporary storage memory, in which the changed route data is output according to a command from the ground, from the area based on the passing time to the area based on the diamond operation start time. Is done.

Conversely, when the application of the changed route data with the timetable for starting the schedule operation as the reference time is scheduled, if the change work progresses quickly and the scheduled work until the passing time is completed, the Since the changed route data corresponding to the changed location should be applied, it is necessary to shift the reference time to a time later than the timetable for starting the schedule operation, for example, to a passing time. In such a case, the purpose is achieved by switching the storage area of the temporary storage memory, in which the changed route data is output according to a command from the ground, from the area having the timetable as the reference time to the time as the reference time. Is done.

The eighteenth configuration is an example in which the same function-improving configuration as the seventeenth configuration is added to the thirteenth configuration, except that the ground equipment is arranged separately in the control center and the operation section. Is the same as in the seventeenth configuration.

The nineteenth configuration is composed of fifth, sixth, seventh, eighth
Alternatively, this is a function provided in addition to the seventeenth configuration. When the updating means updates the storage data in the nonvolatile memory, the update completion detecting means detects this and sends the detected data to the update management data writing means. Update management data writing means,
The detection data and the vehicle identification code are written together as update management data in the data medium from which the route data for updating is read.

When the attendant inserts the route data medium on which the update management data is written into the management data reading means of the ground equipment, the update management data is read and sent to the update status management means, where the data is stored in the nonvolatile memory on the vehicle. The update status, that is, the status of when the route change data has been updated for which vehicle and when, is managed. The twentieth configuration is a function provided in addition to the thirteenth, fourteenth, fifteenth, sixteenth, or eighteenth configuration.
This is the same as the configuration of No. 9.
