BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a route confirmation device for a maintenance vehicle on a railway line equipped with a turnout.

[0002]

2. Description of the Related Art Conventionally, in a railroad track equipped with a turnout, when a maintenance vehicle is run for maintenance and inspection, and especially when it is turned at night, it is difficult to determine the opening direction of the tongue rail of the turnout. Therefore, the maintenance vehicle was temporarily stopped in front of the turnout, and the supervisor disembarked from the maintenance vehicle and checked the opening direction of the turnout before running the maintenance vehicle. The method requires time to check the opening direction of the turnout and run the maintenance vehicle, which is inefficient in working, and the vehicle may run in a different direction due to misidentification of the opening direction, or the turnout may stick out. There is a risk of inducing derailment. In order to solve this problem, a method of displaying an opening direction by attaching a display plate that rotates in conjunction with conversion of the tongue rail portion of the branching device is disclosed in Japanese Utility Model Laid-Open No. 3-50601.
It is proposed in the publication. The method using the rotary display plate has a complicated mechanism and is difficult to confirm at night, which is not satisfactory. Therefore, there has been proposed a route confirmation display device including a solar cell, a storage battery, a display unit, and a control circuit having a timer for setting an operation time zone, and a plurality of the display units arranged in a track.

[0003]

However, in the case of the display device with the timer setting, there is the trouble that the timer must be set for each display unit, and the maintenance vehicle is not operated during the set time of the timer. Since the lighting is displayed regardless of the presence or absence, there is a drawback that an unnecessary lighting signal of the light emitter enters the driver's visual field when a general vehicle that does not need the opening information of the branching device passes by.

[0004]
