Abstract

PURPOSE:To simplify a testing device by providing a vehicle with a regulation controller and test controller and with a memory and, at the time of a test mode, by causing the regulation controller to use data written by the test controller. CONSTITUTION:Various vehicle control signal S01 or test mode identifying signals S02 are taken in a regulation controller 2 via interface 1 to output a vehicle control signal S2. Also, a test controller 2' outputs various input signals for tests. A memory 3 connected with controllers 2, 2' inputs and output data from and to both of the controllers 2, 2'. When the interface 1 detects the test mode identifying signal S02, the regulation controller 2 reads data from the test controller 2' inputted to the memory 3 to output the control signal S2. Thus, a control action test using a test signal input related to a high-tension circuit such as the armature current and field current of a main motor is practiced easily without any particular apparatus.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control device for a railway vehicle that also has the function of testing a vehicle.

[Conventional technology]

Generally, when checking the control state of a vehicle, a test called an empty/chip test is usually performed.

In order to keep the vehicle stationary during this test, the high-voltage circuit of the traction motor, which is controlled by the control device, is disconnected. As a result, signals such as the armature current and field current of the traction motor cannot be obtained, and in order to check the control status of the vehicle, some input signal is required in place of these signals, and generally test signals are used. The conventional method is to prepare a generator and switch its output using a connector, or to add it to the input interface of a vehicle controller.

[Problem to be solved by the invention]

However, according to such conventional methods, it is necessary to prepare a signal generator and switch connectors each time a test is performed. Alternatively, a switching circuit that is not directly related to the control of the vehicle is always connected, and depending on its characteristics, there is a risk that the control of the vehicle itself will be seriously affected.

Furthermore, when it is attempted to incorporate it into a control device, there is a problem in that a large space is required for the functions required only during testing.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention includes a control controller that mainly controls the vehicle, a test controller that mainly tests the vehicle, and a memory that can input and output data from both controllers. The test controller writes data corresponding to the input signal corresponding to the situation to be tested from the test controller to the memory, and only when there is an input signal that identifies that the test controller is in test mode. The object of the present invention is to provide a device with a simple configuration that generates an output for controlling a vehicle using data written by a user.

[For production]

With this solution, it is possible to directly input data equivalent to that obtained through the input interface from the memory, and in particular, the switching circuit between the vehicle control input signal and the test input signal can be removed, and the test signal can be input directly from the memory. There is no need to prepare a generator.

Hereinafter, the present invention will be explained in detail with reference to embodiment drawings.

〔Example〕

FIG. 1 shows the basic system according to the present invention, where 1 is an interface, 2.2' is a controller, 3 is a memory,
801 is, for example, the armature current of the main motor.

Input signal for controlling the vehicle such as field current, 802 is an input signal identifying that the vehicle is in test mode, S2
is the vehicle control output.

That is, the input signal 801 + sow is taken into the controller 2 through the input interface l. Here, the controller 2 performs calculations using these input signals in a predetermined order and derives the control output S2.

The memory 3 is configured so that data can be input and output from both the controllers 2 and 2', and therefore the controller 2 writes data input through the interface 1 or data in the middle of a calculation to the memory 3.

On the other hand, the controller 2' monitors the control state of the vehicle including the operation of the controller 2 by reading data written by the controller 2 in the memory 3.

If an empty notch test is performed with the high-voltage circuit of the traction motor currently being controlled by the control device disconnected, the input signal Sol will be related to the high-voltage circuit such as the armature current and field current of the traction motor. Therefore, it becomes impossible to test control operations using these input signals.

Therefore, data corresponding to the input signal corresponding to the situation to be tested is written in the memory 3 as data in place of these input signals, and the controller 2 confirms that there is an input signal 802 in the test mode, and then The data written in the memory 3 from the controller 2' is used to control the vehicle.

This will be explained using the operational diagram shown in FIG.

That is, when there is no input signal 802, and therefore when the mode is not test mode, the controller 2 uses the data taken in through the interface l to output the control output S2.
On the other hand, the controller in the test mode can generate a control output using the data written by the controller 2'.

In this description, the data that the controller 2' writes into the memory 3 is not limited to data related to the high voltage circuit of the main motor, but may be any input signal. In addition, in the test mode as well as in other modes, by checking the data written by the controller 2 to the memory 3, it is possible to determine how the vehicle operates according to the test data written to the memory 3 by the controller 2'. It goes without saying that it is possible to check whether it is controlled.

〔Effect of the invention〕

As explained above, according to the present invention, the vehicle control l#ζζ
It is possible to provide an exceptional device that has the functions of testing a vehicle without any extra component parts that may have an adverse effect, and without the need to prepare equipment for testing.
