Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for testing an automatic train driving system, particularly a torque control function.

[Prior art]

Conventionally, when using a test device to check whether an automatic train operation system (hereinafter referred to as an ATO device) has a normal torque control function, the test device is used to check the performance of the train that is being controlled by the ATO device. A simulator is used to simulate the characteristics. That is, a torque control command is given to the simulator from the ATO device to operate the simulator, the simulator simulates the movement of the actual vehicle in response to the torque control command, and the result of the simulation indicates that the torque control command is sent normally. I'm trying to check to see if there are any.

[Problem that the invention seeks to solve]

Since this simulator simulates the movements of an actual vehicle as mentioned above, it is expensive, and there was a problem that the test was too expensive.

This invention was made to solve the above problem, and an object thereof is to obtain a test method for automatic train operation equipment that allows testing to be performed without using a simulator.

[Means for solving problems]

In order to achieve the above object, the present invention uses a device that stores a plurality of torque control commands set in an ATO device, an acceleration pattern of a predetermined acceleration, a constant speed pattern of a predetermined duration, and a deceleration pattern of a predetermined deceleration. Means is provided for inputting, as a speed input, an inter-station running pattern signal to the ATO device in which the predetermined acceleration and the predetermined deceleration are lower than the target acceleration and target deceleration set in the ATO device. When the input torque control command is sequentially compared with the stored torque control command and they match, and when the control command sent by the automatic train operation device does not change during the constant speed pattern, respectively. The configuration is such that it sends out an output of "present."

[Effect]

In this invention, a fixed inter-station traveling pattern is input to the ATO device instead of the actual speed input, but the acceleration of the acceleration pattern in this inter-station traveling pattern is lower than the target acceleration set in the ATO device. value, so the ATO device sends out the n-kth torque control command to increase the speed of the train, but since the input acceleration pattern is constant, it sends out the n-k+1th torque control command, which has a higher command value. The second torque control command is sent out, this is repeated, and finally the maximum torque control command is sent out. The above device, which stores the same torque control command as that set in the ATO device, takes in the sequentially sent torque control commands in this way and compares them with the stored torque control commands for each level. However, if the comparison matches, that is, if the torque control command is being sent normally, an output of "Yes" is sent. The same applies to the deceleration pattern. Also, during the constant speed pattern, the device monitors whether the input changes.

〔Example〕

An embodiment of the present invention will be described below.

In FIG. 1, 1 is a pattern signal generator;
Based on the instructions from the computer 2, an inter-station running pattern signal indicated by A in FIG. 2 is output. 3 is an automatic train operation device that receives a predetermined number of torque control commands T (T _Uo , T _K
T _Do , where n=1.2.3.…). The train automatic operation device 3 receives the station-to-station running pattern signal A and sends its output to the computer 2. Calculator 2 is
A predetermined number of torque control commands T _Uo , T _K , T _Do are stored, and the corresponding torque control commands are ATO
When an input is received from the device 3, an output of "present" is sent out.

In Figure 2, A _U is an acceleration pattern, A _K is a constant speed pattern (target speed), A _D is a deceleration pattern,
A _UO and A _DO represent acceleration and deceleration patterns based on the target acceleration α _U and target deceleration α _D set in the ATO device 3, respectively, and S represents the speed limit.

Next, the operation will be explained.

(b) As the acceleration pattern A _U of the check station running pattern signal A of the acceleration torque control command T _Uo ,
An acceleration pattern is given that increases at an acceleration α (<α _U ) lower than the target acceleration α _U . ATO device 3 is
If the train acceleration is lower than the target acceleration α _U ,
Since the configuration is such that the acceleration torque control command T _Uo is output so that the train acceleration reaches the target acceleration α _U , when the signal of the acceleration pattern A _U is input, the acceleration torque control command T is output. _Uo
increases toward the torque control command that gives the target acceleration α _U. However, unlike in the case of actual operation or the simulated test method, the input acceleration α does not converge to the target acceleration α _U but remains constant. A predetermined number of torque control commands T _Uo are sequentially output to the computer 2 for a predetermined time t ₀
After the elapse of , the maximum torque control command is input to the computer 2. Therefore, from computer 2, "Yes" is sent sequentially.
A predetermined number of signals are output. ATO device 3
If the torque control command T _Uo is out of order, any or all of the torque control commands T Uo will not be input to the computer 2.
Therefore, from the output of the computer 2, it is possible to automatically know whether there is a failure in the ATO device 3 and which torque control command circuit is not functioning properly.

(b) Check the deceleration torque control command T _Do. As the deceleration pattern A _D of the station-to-station traveling pattern signal A, give a deceleration pattern that descends at a deceleration α (< α _D ) lower than the target deceleration α _D. As in the case of acceleration, when the deceleration of the train is smaller than the target deceleration α _D , the ATO device 3 issues a torque control command T _Do for deceleration so that the train deceleration converges to the target deceleration α _D. Therefore, when the signal of deceleration pattern A _D is input, as in the case (a) above,
If ATO device 3 is not malfunctioning, ATO
Torque control command for a predetermined number of decelerations that the device has
T _Do is sequentially output to the computer 2, and after a predetermined time _t2 has elapsed, a maximum torque control command is input to the computer 2. Therefore, a predetermined number of "present" outputs appear sequentially from the computer 2. If ATO device 3 is out of order, a torque control command for deceleration is issued.
Because some or all of the T _Do's are not output,
From the presence or absence of the "present" output from the computer 2, it is possible to automatically detect a failure of the ATO device 3 or a torque control command circuit that is not functioning properly.

(c) Constant speed pattern A _K of inter-station running pattern signal A
On the other hand, whether the torque control command T _K at the time when this pattern is given to the ATO device 3 (the elapsed time of the above-mentioned predetermined time _t0 ) does not change thereafter, that is, whether it maintains a constant level. The computer 2 monitors and checks whether or not the
The constant speed control function of the ATO device 3 functions normally by sending out a signal indicating that there is an error when there is no fluctuation, and a signal indicating that there is an abnormality when the fluctuation exceeds the allowable range. You can know whether it is done or not.

〔Effect of the invention〕

As explained above, this invention inputs a certain inter-station travel pattern into the ATO device, and
By having a configuration in which the multiple torque control commands that the ATO device automatically sends out sequentially are collated using a device that stores these torque control commands in advance,
It is possible to automatically check whether the ATO device has a torque control function or not over the entire range.
Moreover, the device only needs to have a device that generates the inter-station running pattern signal and a device that has the function of comparing input with a predetermined number of torque control commands stored in advance, and there is no need to use a simulator. Therefore, it is possible to test ATO equipment at a lower cost than in the past.
