Abstract

PROBLEM TO BE SOLVED: To provide a main control device that achieves improvement in safety.SOLUTION: A comparison operation unit 4 compares the vehicle speed detected by a speed detecting unit 2 with the speed limit for each of a plurality of notch stages stored in a storage unit 3 and settable with a command handle 1. When the vehicle speed detected by the speed detecting unit 2 exceeds the speed limit stored in the storage unit 3 and corresponding to the notch stage currently set with the command handle 1, a power running command to a power running circuit 5 is interrupted.

Description

  The present invention relates to a master controller that controls operation of a railway vehicle based on a steering operation.

  A railway vehicle has a master controller (mass controller) mounted on a cab as an interface for a driver to operate and control the vehicle. The driver's cab is present on both leading vehicles of the train organization. The master controller outputs a notch command serving as a brake (braking) or power running (acceleration) command for the train according to the notch position of the main handle operated by the driver.

As a notch command, there are brake notches with 8 steps and power running notches with 4 steps, and the higher the value, the higher the force. Further, the state of the brake notch 0 and the power running notch 0 is referred to as “Yurume (cut)”, and the vehicle is coasted without acceleration or braking.

  In recent years, the master controller detects the position of the handle by using an angle detection sensor such as an absolute rotary encoder from what detects the position of the handle using the on / off of a contact (switch). The so-called contactless master controller that outputs a notch command based on the above is the mainstream.

  In this type of master controller, control means constituted by a CPU or the like controls power running or deceleration based on a notch command signal corresponding to the absolute position of the handle detected by the rotary encoder.

However, in the above-described master controller, the driver recognizes the speed with a speedometer or the like in a human system, and the driver operates the handle to operate the notch stage (command stage). If there are vehicle restrictions such as gradient, weather, and friction between wheels and tracks, the speed may be exceeded.

An object of the present invention is to provide a master controller capable of preventing safety from being exceeded and improving safety.

  In order to achieve the above object, the present invention is a master controller that is mounted on a railway vehicle and that gives a power running or deceleration command to a vehicle drive device by operating a handle capable of setting a plurality of notch steps. The limit information corresponding to the speed set for each notch stage is stored, and the information corresponding to the vehicle speed based on a predetermined notch signal corresponding to the absolute position of the steering wheel is compared with the stored limit information. The power running or deceleration of the vehicle drive device is controlled based on the calculation result.

  According to the present invention, it is possible to provide a master controller that prevents the speed from being exceeded and improves safety.

The block diagram of the master controller which shows Example 1 of this invention. The block diagram of the master controller which shows Example 2 of this invention.

[Example 1]
Hereinafter, the master controller of Example 1 based on this invention is demonstrated with reference to FIG. FIG. 1 is a configuration diagram of a master controller showing Embodiment 1 of the present invention.

In the figure, 1 is a command handle, which is composed of, for example, a one handle for moving one shaft (rod) back and forth, a brake notch having a strong braking force as it goes to the back, and a power running notch having a strong acceleration force as it goes to the front, The driver selects from a plurality of notch stages and sets the notch command. The rotation axis of the command handle 1 is mechanically connected with a rotation axis of an angle detection sensor such as a rotary encoder (not shown) at a predetermined axial ratio.

Reference numeral 2 denotes speed detection means, which is composed of, for example, a speed generator and detects the actual train speed. Reference numeral 3 denotes a storage means that stores a speed limit set for each of a plurality of notch stages of the designated handle 1.

Reference numeral 4 denotes a comparison calculation means, which is composed of a CPU or the like, and compares and calculates the train traveling speed detected by the speed detection means 2 and the speed limit stored in the storage means 3. At this time, if the speed limit stored in the storage means 3 corresponding to the notch stage set by the command handle 1 is smaller, that is, the train speed detected by the speed detection means 2 is the notch set by the command handle 1. When the speed limit stored in the storage means 3 corresponding to the stage is exceeded, the powering command output to the powering circuit 5 is turned off. Then, when the traveling speed of the train falls below the speed limit by a certain amount, the powering command output to the powering circuit 5 is resumed.

  Reference numeral 6 denotes a stop means, which is constituted by a switch, for example, and stops the operation of the comparison calculation means 4 as described above by the driver's operation, and outputs the notch command intended by the driver by the command handle 1 to the powering circuit 5 as it is. Let

As described above, in the master controller in the first embodiment, the comparison operation means 4 compares the actual train speed and the speed limit stored in the storage means 3 corresponding to the notch stage set by the command handle 1. Since the powering command output to the powering circuit 5 is controlled based on the calculation result, powering acceleration can be performed so as not to exceed the notch speed limit set by the command handle 1, and safety can be improved. Can be improved. In addition, when the train speed falls below the limit speed by a certain amount, the powering command output to the powering circuit 5 of the comparison calculation means 4 is resumed, so that the vehicle can travel at a substantially constant speed, and the riding comfort is reduced. Can be improved. Further, since the operation of the comparison calculation means 4 can be intentionally stopped by the stop means 6, it is possible to flexibly cope with an emergency or abnormality.

[Example 2]
Hereinafter, the master controller of Example 2 based on this invention is demonstrated with reference to FIG. In addition, about the structure same as FIG. 1, the same number is attached | subjected and description is abbreviate | omitted. FIG. 2 is a configuration diagram of a master controller showing Embodiment 2 of the present invention.

  In this figure, the difference from the first embodiment shown in FIG. 1 is that instead of the speed detection means 2, the current value or the main circuit current value to be supplied to the motor for increasing the rotational speed of the motor for power running acceleration is detected. The current detection means 7 is provided. The limit information stored in the storage unit 3 is a motor current value set for each of a plurality of notch stages of the designated handle 1 or a limit current value of a main circuit current value. Further, a cab display 8 is provided to prompt the driver to set a notch step higher than the notch step set by the command handle 1.

  Thus, the comparison calculation means 4 compares the motor current value or main circuit current value detected by the current detection means 7 with the limit current value stored in the storage means 3. At this time, when the limit current value stored in the storage means 3 corresponding to the notch stage set by the command handle 1 is larger, that is, the motor current value or the main circuit current value detected by the current detection means 7 is the command. When the current limit value stored in the storage means 3 corresponding to the notch stage set with the handle 1 is lower than the limit value, the driver is prompted to operate the command handle 1 for setting to a higher notch stage. The notch up instruction is displayed on the cab display 8 as shown.

  As described above, in the master controller in the second embodiment, it becomes possible to support the speed reduction prediction, and it is possible to improve the driving efficiency by realizing the optimum driving interval.

  The present invention is not limited to the first embodiment and the second embodiment, and it goes without saying that various combinations of circuit configurations can be changed.
