[Problem that the invention seeks to solve]

Conventional test equipment is installed on the ground as described above, so it is necessary to park the train in the pit for each test, connect and release the test equipment to onboard equipment, and also require an equivalent signal generator. There was a problem with that.

This invention was made to solve the above-mentioned problems, and an object of the present invention is to obtain an on-board test device for a train that allows tests to be performed on a train.

[Means for solving problems]

The on-board test device for a train according to the present invention connects a transmission central station and an operation display to a leading car having a command unit of a train in which a plurality of cars are connected, and connects the transmission central station to a car equipped with control equipment. The system is equipped with a transmission terminal station.

[Effect]

The on-board test device for a train according to the present invention can execute the test contents set on the operation display by operating the command unit, and can display and store the test results on the operation display.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 to 3 and 6 to 15 are the same as the conventional ones, so explanations thereof will be omitted. 4b is a chopper device, 5b is an arithmetic processing unit, and 21 is an operation display that can set the test number, test content, test order, etc., and display and store test instructions and test results, and is used to ensure the normal operation of the control device 4b. The corresponding first signal and the second signal corresponding to the abnormal operation of the control device 4b are stored and can be output. 22 is a serial transmission line connected to the display 21, and 23 is a transmission central station connected to the serial transmission lines 22 and 24, which decodes the content of the command from the operation display 21 and sends it to the related transmission terminals described below. The information is transmitted to station 25. Furthermore, the measurement data of the control device 4b received from the transmission terminal station 25 is edited as data for the vehicle, including the relationship with measurement data of other devices (not shown). Editing includes, for example, creating a format to display on a display, a format to print out, a format to store, and the like. 24 is a serial transmission line that runs between both leading cars 1a of the train and is connected to the transmission central station 23; 25 is a transmission terminal station that is connected to the serial transmission lines 24 and 26, and which receives commands from the transmission central station 23; It is decoded and the test conditions are instructed to the control device 4b to be tested. Furthermore, the transmission terminal station 25 edits the measurement data into a predetermined format in the control device 4b and transmits it to the transmission central station 23. 26 is a serial transmission line connected to the transmission terminal station 25, and 27 is a transmission interface connected to the transmission terminal station 25 via the serial transmission line 26, which is provided in the arithmetic processing section 5b. The arithmetic processing unit 5b provides test conditions such as in what order and what kind of measurements to perform and at what timing to perform them within the control device 4b. Then, the measured data such as voltage and current is edited into a predetermined format and transmitted to the transmission terminal station 25.

As shown in FIG. 1, such an on-board testing device for a train has an operation display 21 and a transmission central station 23 installed in a vehicle having an operation control room of a train 1, that is, a leading car 1a, and a control device for controlled equipment. That is, a transmission terminal station 25 is installed in the vehicle 1b on which the chopper device 4b is mounted, and when the train 1 has leading cars 1a at both ends, a transmission central station 23 is installed in each leading car 1a. The operation display 21 is detachably connected to the transmission central station 23, and is normally stored at the factory so that it can be connected to a predetermined transmission central station 23 as needed.

Next, the operation will be explained. Operation display 21
When the test number, test items, test contents, test procedure, etc. are set and inputted, they are stored in the operation display 21 and displayed on the display section. Furthermore, the operation display 21 sets a test mode that includes the operation of the protective device in normal operation or abnormal operation of the control device 4b,
output signals. Then, according to the display on the operation display 21, test conditions are sequentially set. The calculation control unit 5b inputs the set test conditions to the operation display 21. As a result, data based on the amount of feedback from each detector corresponding to the test number stored in the operation display 21 is input to the arithmetic processing section 5b via the serial transmission lines 22, 24, and 26. . Therefore, the operation results in response to the test commands, such as the phase control amount of the chopper thyristor 13, sequence control, and the operation of the protection device, etc.
Since the data is displayed on the display section, the operator sequentially proceeds to the next test item while confirming the displayed contents, and tests the operation and performance of the chopper device 4b.

Here, the quality of the chip thyristor 13, the current detector 15, the input circuit 7, etc. is confirmed by a running performance test during a running test run after the stationary test, conventionally and also in the present invention. .

FIG. 2 shows another embodiment of the invention, in which the command unit 2 and the transmission central station 33 are connected by a cable 34, and the test conditions according to the commands of the command unit 2 are transmitted directly to the calculation control unit 5b via the transmission line. The control line between the command units 2 and 2 is omitted, and the same operation as in the above embodiment is expected.

In addition, in the above embodiments, the command unit 2
The case in which the control device 4b is operated has been explained above, but in the case of an unmanned train whose operation is controlled by a computer in a central control room without installing the command device 2 in the leading vehicle, the operation display device 21 and the command device 2 may be operated. By using an operating device having this function, tests can be performed even from a vehicle where the command unit 2 is not installed.

In the above embodiments, the case where the device to be tested is a chopper device has been described, but the present invention can also be applied to devices including a microcomputer, such as a brake device or a stationary inverter device. Furthermore, although we have described the case where the test contents and test results are displayed on the display, since it is possible to judge whether the test results are good or bad, it is also possible to print them out as a test report by connecting to a printing device. Furthermore, by installing a data management device on the ground and inputting the collected data into the data management device, it becomes possible to create equipment deterioration tracking reports from long-term data.

〔Effect of the invention〕

As described above, according to the present invention, an operation display device and a transmission central station are arranged in the lead vehicle having a command unit, a transmission terminal station is arranged in a vehicle on which a controlled device is mounted, and settings are set on the operation display device. This provides the advantage of being able to carry out on-vehicle tests in which test items are executed using the command unit and confirmed on the operation display.
