Description

Description: TECHNICAL FIELD The present invention relates to a railway vehicle control device having a function of testing a vehicle.

[Conventional technology]

Generally, when checking the control state of a vehicle,
A test called an empty notch test is performed. In this test, in order to keep the vehicle stationary, the high voltage circuit of the main motor, which is the control symmetry of the control device, is cut off. As a result, signals such as the armature current and the field current of the main motor cannot be obtained, and some input signals instead of these signals are required to check the control state of the vehicle. In order to prepare a generator, a method has been adopted in which the output is switched by a connector or added to an input interface of a vehicle control controller.

[Problems to be solved by the invention]

However, according to such a conventional method, it is necessary to prepare a signal generator for each test or switch the connector. Alternatively, a switching circuit that is not directly related to the control of the vehicle is always connected, and depending on the characteristics thereof, there is a possibility that the control of the vehicle itself may be seriously affected. Also, if you try to incorporate it in the control device,
There is an inconvenience that a large space is required for functions required only at the time of testing.

[Means for solving the problem]

The present invention solves the above-described problems by providing a control controller mainly for controlling a vehicle, a test controller mainly for testing a vehicle, and a memory capable of inputting and outputting data from both controllers. , And writes data corresponding to an input signal corresponding to a situation to be tested from the test controller to the memory, and the control controller only controls the test controller when there is an input signal for identifying the test mode. The present invention provides an apparatus having a simple configuration in which a control output of a vehicle is generated by using data written by the apparatus.

(Operation)

With such a solution, the function of directly inputting the data equivalent to the data taken in through the input interface from the memory can be exhibited. In particular, the switching circuit between the vehicle control input signal and the test input signal can be eliminated, and the signal for the test can be removed. There is no need to provide a generator.

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

〔Example〕

FIG. 1 shows a basic system according to the present invention, wherein 1 is an interface, 2, 2 'is a controller, 3 is a memory, S
_01, for example an armature current of the main motor, the input signals for controlling the vehicle such as the field current, S ₀₂ is the input signal, S ₂ is the output control of the vehicle to identify that the test mode of the vehicle .

That is, the input signals S ₀₁ and S ₀₂ are taken into the controller 2 through the input interface 1. Here, the controller 2 in accordance with the order determined in advance, and calculating with these input signals, derives the control output S _2. The memory 3 is configured so that data can be input and output from both the controllers 2 and 2 ′. Therefore, the controller 2 writes data input through the interface 1 or data during a calculation into the memory 3.

On the other hand, the controller 2 '
The control state of the vehicle including the operation of the controller 2 is monitored by reading the data written in the.

Here, when the empty notch test is performed in a state where the high-voltage circuit of the main motor to be controlled by the control device is cut off,
Of the input signal S _01, the armature current of the main motor, can not be obtained input associated with high-voltage circuit such as a field current, can not be tested in the control operation using these input signals.

Therefore, data corresponding to the input signal corresponding to the situation to be tested as data replacing these input signals is stored in the memory 3.
After the controller 2 confirms that there is an input signal _{S02 in the} test mode, the controller 2 performs a vehicle control operation using the data written in the memory 3 from the controller 2 '. This will be described with reference to the operation explanatory diagram shown in FIG.

That is, the controller 2 is input signal when no S _02, therefore when the non-test mode, the control output S ₂ with the acquired data through an interface 1
And in the test mode, a control output can be generated using the data written by the controller 2 '.

In the present invention, the data written by the controller 2 'to the memory 3 is not limited to the high voltage circuit of the main motor, but can be any input signal. In the test mode, as in the case of the mode other than the test mode, the controller 2 checks the data written in the memory 3 to determine how the vehicle responds to the test data written in the memory 3 by the controller 2 ′. Needless to say, it can be confirmed whether or not it is controlled.

〔The invention's effect〕

As described above, according to the present invention, a function of testing a vehicle is provided without an extra component that affects the control of the vehicle, and without preparing a device or the like for testing. Special equipment can be provided.
