Field of the Invention The present invention relates to a locomotive direction switching confirmation device used for a diesel locomotive or the like, and particularly to a command for a forward / reverse direction or a left / right traveling direction on a Y-shaped road, for example. The present invention relates to a locomotive direction switching confirmation device that confirms whether a locomotive is traveling in a street direction.

の進行方向を変えている。[0003] In this diesel locomotive, the driver on the ground controls the speed while manually operating the wireless device, and when the traveling direction is desired to be changed, the reverse device switching signal is similarly transmitted using the wireless device. In other words, when switching the reversing device of the locomotive, “1” is maintained while the brake is applied.
A forward or binary command is issued, the torque converter is stopped by loosening the brake, and the engagement direction of a gear called a reverser is changed to change the traveling direction of the locomotive.

上の無人運転制御装置に伝送できない。On the other hand, in recent years, unmanned operation of an unmanned hydraulic diesel locomotive has been considered. In this unmanned driving method, the installation of the inverter status indicator is meaningless because the driver cannot visually check the inverter status indicator on the ground, and the operation control and progress to the locomotive control system are performed wirelessly. Although it is possible to issue a direction command, it is impossible to transmit on-board information to an unmanned operation control device on the ground.

In addition, it is necessary to provide a transmitter, etc., which increases the cost, and uses only 40 frequencies defined by low-power radio. If so, there is a risk of interference.

置とを設けたものである。In order to solve the above-mentioned problems, the present invention transmits a direction switching command from a ground side via a radio transmitter, and transmits the traveling direction through a radio reception controller mounted on a locomotive. In a locomotive direction switching confirmation device for switching a traveling direction of a switch, a detection sensor for detecting a traveling direction of a locomotive is installed near a predetermined direction switching position on a locomotive traveling path, and the direction switching command and the detection are detected. An operation determining device is provided for comparing the output signal of the sensor and determining whether the traveling direction switch has been switched according to the direction switching command.

ことがあっても進行方向切替器の切替状態を確実に判断
できる。Therefore, by adopting such means, the switching state of the traveling direction switch can be determined by comparing the direction switching command with the output signal of the detection sensor without providing the locomotive with a transmission function. Even if the locomotive is hidden by the building, the switching state of the traveling direction switch can be reliably determined.

検出できる。It is to be noted that at least one detection sensor is provided in the locomotive traveling direction near the direction switching position. If a plurality of detection sensors are provided in the same direction, a detection signal from any of the detection sensors in the same direction is provided. Thus, the traveling direction of the locomotive can be detected.

判断手段とで構成する。Further, the operation judging device may have the following several configurations. One of the means is to send a brake command and a direction switching command, and to compare the direction switching command with the output signal of the detection sensor after the direction switching command. The first switching means determines that the direction switching is normal when the device is switched according to the direction switching command, and the second determining means determines that the direction switching is incomplete when the direction switching command is not fulfilled. .

In the case of incompleteness, it is possible to create a state in which retry is performed again so as to quickly switch to the required traveling direction.

で構成する。Another one is that a brake command and a direction switching command are continuously transmitted for a certain period of time, and then a slow speed command is transmitted, and the direction switching command is compared with the output signal of the detection sensor after the direction switching command. A first determining unit that determines that the direction switching is normal when the traveling direction switch is switched according to the direction switching command, and transmits a high-speed command; and the direction switching command. If it is not, the second switching means determines that the direction switching is incomplete.

を確実に判断する。[0016] By adopting such means, by continuously transmitting the brake command and the direction switching command for a certain period of time, the switching of the traveling direction can be carried out smoothly, while the low-speed running state is created and the direction switching command is generated. By comparing the output signal of the detection sensor with the output signal of the locomotive, detection of the traveling direction of the locomotive is facilitated, and it is reliably determined whether the direction switching is normal or incomplete.

る。Further, the second determining means determines whether or not the detection is performed by the other detection sensor having a different traveling direction when the direction is not in accordance with the direction switching command, and the detection is performed by the other detection sensor or the other detection is performed. If a certain time has elapsed rather than the detection of the detection sensor, a retry for sending the brake command and the direction switching command is performed again.If the same result is obtained despite the retry, a direction switching failure is determined. Since the judgment is made, it is possible to switch to the required traveling direction by retry, and in the case of a direction switching failure, necessary measures can be taken promptly.

The unmanned operation control device 14 controls the locomotive 1 based on the operation control command.
When the vehicle is driven at a predetermined traveling speed for a predetermined time and approaches a direction switching point for switching a predetermined traveling direction, a switching processing command of the reverse inverter 4 is transmitted to the operation determining device 13.

That is, when the operation determining device 13 outputs the brake command and the reverse inverter switching command (S1, S2), the wireless transmitter 11 continues to transmit the brake command and the direction switching command for a certain period of time.

As a result, by continuing to issue the command of the reversing device "one-way" with the brake applied, the traveling direction is changed by switching the reversing device 4.

ことが可能となる。According to the second aspect of the present invention, the effect of the first aspect of the present invention is included, and the switching state of the traveling direction switch can be detected using a smaller number of sensors. According to the third aspect of the present invention, it is possible to reliably determine whether or not the direction switching command is met, that is, whether the traveling direction switch is normal or incompletely switching the traveling direction switch, and proceed using an unmanned operation determination device installed on the ground side. The switching state of the direction switch can be accurately determined. In particular, when the traveling direction switching device is incompletely switched, it means that the traveling direction switching device is in a neutral state, so that it is possible to create a retry opportunity again.
