DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention utilizes a data depot defined as a storage device capable of accessing stored information from the outside in a non-contact manner. The present invention relates to a rail tonnage management device for managing a certain tonnage.

[0002]

2. Description of the Related Art Generally, as one of maintenance work of a railway,
Maintenance work such as replacing rails can be raised,
The time of this rail exchange is determined by the tonnage of the train passing through the rail. Conventionally, the tonnage of a train passing through a rail is calculated by a train schedule.

[0003]

However, in the conventional method of calculating the tonnage, the tonnage of each train actually passing through is not taken into account because the tonnage is calculated by the train schedule. There is a problem that an error occurs with the tonnage. The present invention has been made in view of the above-described conventional problems, and has as its object to provide a rail tonnage management device that can accurately manage the tonnage of a train passing through a rail.

[0004]

According to the present invention, in order to achieve the above object, a data depot storing tonnage information of a train passing through a rail is arranged along the rail, and the train passing through the rail is provided with the data depot. A writer for writing the number in the data depot is provided, and the tonnage of the rail is managed by reading the tonnage written in the data depot.

Further, according to the present invention, a data depot for storing tonnage information of a train passing through a rail is arranged along the rail, a reader / writer is provided on the train, and every time the train passes through the rail, the data depot is integrated from the data depot to the train. The tonnage of the rail may be managed by reading the value and writing the value obtained by adding the own tonnage.

[0006]

According to the present invention, with the above configuration, each time a train passes, the tonnage is written in the data depot by a writer provided in the train. Therefore, by reading and integrating the tonnage written to the data depot every time it passes, the tonnage of the train can be accurately managed.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram showing an embodiment of a rail tonnage management device according to the present invention. In FIG. 1, a data depot 1 is arranged along a rail 4, for example, for each of a plurality of rails, and has an area for storing tonnage information for each train 6 passing through the rail 4, as shown in FIG. Have. A reader / writer 5 is attached to the train 6 so as to pass over the data depot 1 in close proximity, and the reader / writer 5 writes the tonnage of the own train 6 into the data depot 1.
Therefore, every time the train 6 passes, the history of each tonnage is written in the data depot 1.

For example, a maintenance vehicle having the reader / writer 5 attached thereto is run periodically as in the case of the train 6, or a worker reads the tonnage of each train 6 from the data depot 1 using the portable reader / writer 5. By multiplying, the tonnage of the plurality of trains 6 passing through the rails 4 can be obtained. Next, the configurations of the data depot 1 and the reader / writer 5 will be described in detail with reference to FIG. Data depot 1
In the example, a command signal and data modulated and transmitted by the reader / writer 5 are received via the receiving coil 10, demodulated by the receiving circuit 11, and applied to the memory controller 13. The reception voltage of the reception coil 10 is applied to the power supply circuit 12, rectified and smoothed, and a power supply voltage + Vc for each circuit is generated.

The memory controller 13 has an EEPROM
Read and write of the non-volatile memory 14 are controlled by the memory controller 13.
Is read out from the transmission circuit 15 and transmitted to the reader / writer 5 via the transmission coil 16. The reader / writer 5 is provided with a processor 20 for controlling the reading and writing of the data depot 1, and the processor 20 executes the reading and writing in response to an instruction from a host device. The host device includes a man-machine interface having a keyboard for reading and operating tonnage data from the data depot 1 and an operation unit for calculating tonnage, and this man-machine interface displays the tonnage. A display unit and a printer for printing out are provided.

In the reader / writer 5, a transmission command and data from the processor 20 to the data depot 1 are transmitted through the transmission coil 22 after being modulated by the transmission circuit 21. Further, the signal transmitted from the data depot 1 is received through the receiving coil 23 and then received by the receiving circuit 2.
4 and applied to the processor 20. The communication method between the data depot 1 and the reader / writer 5 is as follows.
For example, from the reader / writer 5 to the data depot 1, FS
This is performed by the K modulation method, and data depot 1 to reader / writer 5
Is performed by a spread spectrum method. Such a data depot 1 and reader / writer 5 are disclosed in, for example,
Nos. 184781 and 2-63349, 2-
Since it is disclosed in JP 89431, a detailed description is omitted.

In the above embodiment, the tonnage of the train 6 is written in the data depot 1 as it is. For example, a symbol is written for each rank of the tonnage, and the symbol is converted to a tonnage at the time of reading and integrated. It may be. Further, the tonnage may be integrated and written each time the train passes, and the integrated value up to that time may be always stored.

[0012]

As described above, according to the present invention,
Each time a train passes, the writer provided for that train writes the tonnage to the data depot, so by reading and integrating the tonnage written for each pass to the data depot, the train tonnage can be accurately calculated. Can be managed.
