Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention collects and accumulates information regarding abnormal operations of various devices mounted on monitoring devices, especially each vehicle in a train, and uses the information for failure analysis. The present invention relates to a monitoring device for a railway vehicle that is used for various purposes.

[Prior art]

To facilitate understanding of the features and advantages of this invention,
First, an outline of a conventional railway vehicle monitor device will be explained.

Figures 1 to 3 include, for example, Japanese patent application No. 5g-9'), t
A conventional railway vehicle monitor device shown in 9 is shown. As shown in Figure 1, the leading car ■, the middle car It
,■,..., and a trailing car N, each car is equipped with various rolling stock devices 3 whose operating states must be constantly monitored, and furthermore, these rolling stock devices The terminal station unit 3 is also installed to detect abnormal operation and collect information at the time of abnormality. The leading car I is equipped with a central station, and the intermediate car IT, m
, . . . and the terminal station mounted on the rear vehicle N are transmitted to and stored in this central station via a transmission line connected through all the vehicles.

Note that if the central station / is also equipped with the functions of the terminal station λ mounted on another vehicle, there is no need to separately mount the terminal station λ, so Fig. 7 shows such a configuration (Fig. 7c). Although shown, it goes without saying that the terminal station may be provided separately as in other vehicles.

The information transmitted from each terminal station to the central station is
The data is stored in the memory, but it can also be monitored at all times on the left side of the display panel.

When you want to read the information stored in the central station, connect the reader to the central station and transfer all the monitoring information collected and stored in the central station to the reader. . Next, the reader 6 is removed from the central station and carried to the location where the external output equipment is installed, and the second
As shown in the figure, is there an external output device for the continuous output device? , g to output the monitoring information transcribed to the bladder ejector B in the required format. The external output device 1g outputs the monitoring information collected and stored at the central station in a required format, that is, in a format that is easy for humans to understand, such as an X-Y plotter, printer, or oscillograph. .

In Figure 3, a reader 6 is connected to the central station l to transcribe monitoring information, and then to external output devices q and g installed on the ground.
This shows how it is output to.

When output of the monitoring information of the reader B is requested, as shown in FIG. 2, for example, a printer g and an X-Y plotter 7 are connected to the reader B as external output devices.

Then, the printer g outputs the monitoring information, that is, the information when the vehicle equipment malfunctions, as shown in FIG. ATC signal/j, notch command/4. In addition to outputting general information such as display table contents 77, the X-Y plotter 7 outputs detailed data necessary for failure analysis in the form of a graph as shown in FIG. That is, in FIG. 5, s/ is general information on the occurrence of a failure, and 2.2 is a graph showing details of the failure, for each of the 73 items (monitoring items), corresponding to the time of 2g. By drawing a time chart, the operator can use the time chart to investigate the cause of the failure. Although the collection of monitoring information by the monitor device is limited by the storage capacity of the central station, it is usually possible to collect and store monitoring information for a plurality of abnormal operations. If multiple pieces of monitoring information are collected, can the accumulated information be sent to an external output device for failure analysis? , g, one by one is output to the generated j@.

The conventional monitor device is as described above, but with such a conventional monitor device, the monitoring information collected and accumulated by the monitor device cannot be processed unless it is output by an X-Y block or the like. It is not known whether the appropriate information is being collected, and therefore failure analysis is not possible. Therefore,
Even if information is collected that is not actually useful, it still has to be printed out, which is a waste of time and money. However, as the amount of monitoring information increases, storage becomes troublesome in terms of space and organization.

[Summary of the invention]

This invention provides a new monitor device that overcomes the problems of the conventional monitor device described above. The above-mentioned problem was solved by having a personal computer (abbreviated as "N") perform output control.In other words, the personal computer was fixedly installed on the ground side in combination with an external output device, and a reader was used to connect the central station on the vehicle. The monitoring information transferred from the computer is transferred again to the computer on the ground, and the monitoring information transferred to the computer is not immediately output to an external output device, but is output to the external output device 46. on the screen of the computer's CRT display device. Once displayed in a format that would be output to a device, the operator can
The device contents on the 'I' display device are checked and only the necessary information is outputted from an external output device1.In addition, the computer monitoring information is recorded using a floppy disk device. . 1 [Examples of the Invention] This invention will be revised and described below with reference to Examples. FIG. 6 is a block diagram showing the configuration of the present invention, and the blocks are indicated by the same '6j't=; as in FIGS. 1 to 3. Also, the blocks are based on the prior art. , which shows a device similar to that of . Therefore, as is clear from FIG.
In addition, the monitor device of the present invention is the same as that of the prior art in terms of on-board devices, and the monitoring information of the on-board devices on each vehicle is collected and stored in the central station of the leading vehicle, and is continuously updated as necessary. It can be said that they are basically the same in that they are transferred to the device and read out from the external output device 9 by the ground device.

However, in this invention, the information from the reader B is not directly outputted from the external output device 7g as in the prior art, but the information from the reader B is once transferred to the PC computer, and then the information is output from the external output device 7g. As shown in Figure 7, the information is displayed on the panconte's CRT display device 9a to check the contents of the monitoring information 7, and only the necessary information is filed and saved in the floppy disk device/θ, and it can be saved as needed. External output device 7. g to obtain a hard copy in the desired format. Therefore, the feature of the monitoring device according to the present invention is that the central station l collects and stores fjf.
The present invention has the advantage of eliminating the limitations of conventional monitor devices by outputting the monitored information via a personal computer.

〔Effect of the invention〕

As mentioned above, in the past, in order to determine whether or not the collected monitoring information was useful for failure analysis, it was necessary to output it to an external output device, but with this invention, Since a determination can be made once confirmed using the CRT display device of a personal computer, there is no need to output unnecessary data, and only the data necessary for failure analysis can be efficiently extracted. In addition, since the monitoring information is recorded on the floppy disk device via the pan controller, the monitoring information can be managed using the floppy disk, which improves the space factor and allows past data to be easily stored on the KCRT at any time. Since it can be viewed on a display device and can be output to an external output device if necessary, it has become possible to permanently store the monitoring information and at the same time it can be easily read out. Note that the computer does not need to be used exclusively as a monitor device;
General technical calculations, except when processing monitoring information.
Of course, it can be used for office work calculations, etc., and as software, for example, trouble handling pack-') 1. If you prepare the computer on a floppy disk, you can freely process various information by replacing the software (floppy disk).
