The central station 3 is also equipped with an operation input section for output commands, an output circuit to the output device 6, and a data processing section.

[Problems with conventional technology]

In the conventional vehicle monitoring device using built-in program control as described above, when pursuing further multi-functionality and higher precision, it is inevitable that
Bring about an increase in hardware and software.

Needless to say, an increase in hardware and software results in an increase in production costs. According to the results of research conducted by the present inventors, in addition to this, the following specific problems are expected to occur.

As the amount of hardware increases, the layout of the driver's cab becomes difficult and the comfort of the driver's cabin deteriorates.

As the amount of software installed on trains increases,
Inversely proportionally, the reliability of the vehicle decreases.

As the amount of software installed on trains increases,
This makes it difficult to take countermeasures when functions are added or changed.

This makes it difficult to respond to requests for shorter delivery and shorter construction times for various equipment installed on trains (normally, trains need to be shipped from the factory 4 to 6 months earlier than the completion of the train).

In other words, in the conventional vehicle monitoring device,
As we strive for greater functionality and higher precision, the resulting hardware and software requirements tend to make the overall equipment heavier and larger, and the internal structure becomes even more complex. However, on the other hand, due to the special reason that it is a vehicle-mounted device, it is subject to various restrictions in terms of appearance, performance, and economy.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a vehicle monitoring device whose functions can be improved without being subject to external or economic constraints.

[Means for achieving the purpose]

In order to achieve the above object, in this invention, the mounting part of the vehicle monitoring device is provided with only the function of simply collecting and recording information and the function of providing information to the crew during normal business operation, and other functions. The function of editing information required during vehicle inspection and repair, outputting it to an output device, or displaying it is carried separately from the mounting part as a monitor operation panel, and when necessary, the two can be connected and data can be transferred. The feature is that it is configured to perform processing and output.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

Figure 3 shows the system configuration of the vehicle monitoring device, including terminal stations 1a, 1b, 1c...1n, and central station 2.
3. The system configuration of the crew display 4 is the same as the conventional one described above. However, many functions that the central station had in the past have been moved to the monitor operation panel 23a outside the mounting section A, and the display 5 for operators (test drivers, vehicle inspection and repair personnel, maintenance personnel, etc.) equipment 6,
The operation unit 7 is connected to a monitor operation panel 23a. That is, the monitor operation panel 23a, the operator's display 5, the output device 6, and the operation section 7 are all non-mounted parts and are arranged on the ground side.

The central station 23 and the monitor operation panel 23a are separated during commercial operation, and are connected as necessary during test runs, vehicle inspections, etc. As shown in FIG. 4, the transmission control unit 8 , the memory section 9, the display interface 10, and the crew display 4 are carried by the central station 23 of the mounting section A, and the command section 11, the data editing section 12, and the output device 13 are carried by the monitor operation panel 23a outside the mounting section A. The display device 5,
An output device 6 and an operation section 7 are connected and configured.

〔Effect of the invention〕

With the above configuration, only a circuit for exchanging data with the monitor operation panel 23a needs to be added inside the central station 23, and no interface circuit is required between the output device 6 and the display 5. . Also, inside the central station 23, the data is simply transferred from the memory section 9 to the monitor operation panel 23a without any special editing of the data.
It is now sufficient to simply send data to , which greatly simplifies the data processing function.

On the other hand, since the monitor operation panel 23a is not mounted on the vehicle, it is less subject to restrictions on shape, size, and environmental conditions. Further, it can be connected to devices having specific functions depending on various uses. For example, it can be connected and used as appropriate to a dedicated operation panel for test runs that outputs train running curves, etc., or an operation panel for outputting failure data with a failure cause tracking function, making it possible to demonstrate excellent functionality. It is.

The above-mentioned effects can be stated more specifically as follows.

The amount of hardware and software installed in the vehicle can be reduced to about half, making it extremely economical.

In normal train production, 20 of the same model
Although ~30 trains will be manufactured, only one monitor operation panel is required according to the present invention. The economic effects of this are extremely large.

The on-vehicle part is smaller and lighter, which makes it easier to layout the driver's cab, improves comfort, saves energy, and downsizes the driver's cab, and the accompanying economic effects are also large.

It will be much easier to respond to short construction and delivery times for various equipment installed on trains (normally, trains are required to be shipped from the factory 4 to 6 months earlier than the completion of the train). According to the configuration of the present invention, the hardware and software of the vehicle mounting part,
In particular, this not only reduces the amount of software to be produced, but also makes it possible to ship monitor operation panels and the like for non-vehicle mounted parts even after the vehicle is completed.

Reducing the amount of hardware and software installed on a train means that the reliability of the train is correspondingly higher, which can be expected to improve the operational efficiency of the train. Improving the operational efficiency of assets that cost over a billion yen per train is economically significant and will also lead to improved services for passengers. Even if a failure occurs in the output function, the train will not go down, further improving operational efficiency.

Even if a function is added or changed, it can be handled on the monitor operation panel side, so there is no need to take the trouble of suspending trains, and therefore, operational efficiency is not hindered.

As described above, according to the present invention, a vehicle monitoring device having highly functional data processing and input/output functions can be realized in a small size and economically.
