Description

[Detailed Description of the Invention] The present invention relates to an onboard information processing device on a train that makes it possible to shorten train runtime and streamline vehicle maintenance.

In recent years, in-vehicle equipment has widely adopted the latest complex technologies such as semiconductors, making it impossible to deal with failures using conventional preventive maintenance alone.In addition, when an abnormality occurs during commercial operation, it is necessary to understand the nature of the accident and take appropriate measures. It's becoming very difficult. Therefore, in order to investigate the cause of the accident, trains may be stopped longer than necessary, causing disruption to the train schedule and affecting subsequent trains.

In addition, a great deal of effort and time is spent searching for the causes of accidents and restoring faulty trains, which is significantly impeding train operational efficiency.

In addition, the need for collecting operation data of equipment at the time of accidents, etc., and outputting records, etc., is increasing day by day, such as the need for operation records during unmanned operation.

Conventionally, when a certain device in a certain vehicle breaks down, a terminal station collects data before and after the failure, and when the vehicle is forwarded when the vehicle is out of order, the data necessary for failure analysis or trouble shooting results is determined. The minimum necessary data is transmitted to the central office via a transmission device, and the failure data is sent to a printer or XY at the factory.
It was output to a recorder, etc., and the inspection staff analyzed the data and repaired it.

However, it is normal for the people who drive the trains and the people who maintain them to be completely different organizationally, and there are usually several people intervening between them to communicate their intentions.

For this reason, it is often impossible to communicate whether there is an abnormality during train operation and whether data is being collected or which of the two central stations is collecting data. Nowadays, it is common for a train to have around 10 cars, and maintenance personnel have to go to both lead cars, which are 200 to 500 meters away, to check whether data is being collected.
In addition, it was necessary to transport heavy and large output devices such as printers each time. This hindered efficiency.

The present invention was developed to solve the above-mentioned drawbacks by displaying on the operation display panels of both leading cars which leading car's central station is collecting the data that should be output to the output device. To provide an onboard information processing device on a train that can efficiently repair failures.

The figures will be explained below. In Figure 1,
1 and 2 are leading cars, 3 and 4 are intermediate cars, 5 to 7 are devices to be monitored mounted on each of the above cars 1 to 3, 8 to 10 are sensors for collecting data, 11 to 13 is a terminal station data processing device with a built-in computer that is installed in each of the vehicles 1 to 3 and collects and makes judgments on the operating status data of each of the devices 5 to 7;
14 to 16 are transmission devices for terminal stations; 17 and 18 are recording devices based on information from each of the terminal stations 11 to 13;
A central station data processing device with a built-in computer that performs processing such as judgment, display, and output, 19 and 20 are operation display panels 21 and 22 that input operation commands or display the results processed by the central stations 17 and 18.
2 is a transmission device for a central office that converts parallel data into serial data and sends and receives data between the central stations 17 and 18 and the terminal stations 11 to 13; 23 is a transmission line; 24 and 25 are the central stations; This is an output device such as a printer, an XY recorder, etc., which outputs the details of the accident, the cause of the accident, and the operation data of each device at the time of the accident as a result of processing by 17 and 18.

Next, the operation will be explained. Assuming that the train is moving toward the left in Figure 1,
The central office 17 is the main office, and the central office 18 is the subordinate office. In this case, the operation differs depending on the purpose of use, but as an example, when an abnormality occurs in the equipment 6 of the intermediate vehicle 3, the terminal station 12 related to the abnormality transmits the related data etc. collected by the sensor 9 to the central station 17. . The central station 17 comprehensively evaluates the accident history and the relationship with other vehicles, and communicates the accident situation to the crew and gives instructions for emergency treatment. In addition, the central station 17 records and outputs data on magnetic tape, memory, printer, etc., such as the operating status of each device before and after the accident, which is fed back to the factory for repair.

FIG. 2 is a functional block diagram of the central office. In the figure, 26 is an indicator light indicating that data is being collected at the central station of one of the leading cars (referred to as central station 1 here), and 27 is an indicator lamp of the other leading car (referred to as central station 2). ), 28 is a reset switch for initializing the hardware or software, 29 is a computer (CPU) that processes the data collected from each terminal station, etc., and 30 is a program. and a storage device that stores and collects data; 31 is the above CPU;
A digital output device controlled by 29,
32 is a digital input device controlled by the CPU 29 and inputs commands from the operation display panels 19, 20, etc.; 33 is a printer or an XY An interface device 34 that outputs data to a recorder or the like is a bus through which the CPU 29 sends and receives data to control the terminal device. Note that the directions of arrows between the input/output devices 32, 31 and the respective central stations 17, 18 indicate other input/output information.

Next, the operation will be explained. It is assumed that the train is running in a direction in which the central station 17 shown in FIG. When an accident occurs while driving and accident information is sent from a certain terminal station to the central station 1, the CPU 29 stores the data in the storage device 30 and outputs the indicator light 26 via the digital output device 31. Lights up to indicate that data has been collected at central station 1. at the same time,
Information to that effect is sent via the transmission device 21 to the central station 18 at the other end. At that time, the central station 18 operates the operation display panel 2.
0 indicator light 26 is turned on to indicate that data has been collected at the central station 1. In this case, the central office 18 has become a subordinate function of the central office 17. In other words, the central office 17 is a key station. Conversely, if the central station 18 is the key station, the indicator lamp 27 of the data collection central station 2 is turned on as accident information is collected, as described above. After outputting the collected data to a printer, XY recorder, etc., if the collected data is no longer needed, the data in both central stations 17 and 18 can be deleted using a reset switch, etc., and new data can be constantly stored in a limited memory. Can be collected in Elijah.

According to this invention, by displaying which central station is collecting data on the display and operation panels of both central stations, it is possible to check which central station can output data from which cab by checking only one central station. is immediately obvious.

200 if there are more than 10 cars per train, as is the case recently.
It can reduce the effort when you have to walk ~400m. In addition, it is possible to determine whether or not data is being collected, and to improve work efficiency, such as whether or not output is necessary and the appropriate transportation of output equipment.
This will greatly help improve maintenance management and reduce the runtime of broken trains. In addition, in such a system, both central stations can use exactly the same hardware and software, which has many advantages, such as improved user maintenance and replacement with spare parts in the event of a failure.

Although the above embodiment has been described in the case of a failure, the present invention is not limited to this. Further, although the output device is generally placed on the ground side in many cases, it may be installed on the vehicle. Further, in the embodiment, the central station (information processing device), operation display panel, output device transmission device, etc. are shown separately, but they may be integrated into one in the configuration of the device. Furthermore, although the central station is placed in the lead car, it is also possible to have the terminal station coexist with the central station depending on how the hardware is organized.
