Abstract

PURPOSE:To improve operability by outputting an early loading operation starting command to an air compressor control circuit when the necessity of early loading operation is judged from early loading operation permitting command information by an operator and information from various detecting circuits to incorporate remote control rolling stocks, and outputting a stopping command when it is judged as unnecessary. CONSTITUTION:When an operator transmits an early loading operation permitting command to a locomotive by a wireless transmitter 1, a wireless communicator 4 receives the command, and converts it into an electric signal on the early operation permitting command, and outputs it to a control device 5. The control device 5 judges the necessity of early loading operation according to output of an air resevoir pressure condition detecting circuit 6, a stopping condition detecting circuit 7, a locomotive abnormality detecting circuit 8 and an early loading condition detecting circuit 6 while including the electric signal. When it is judged as necessary, an early loading operation starting command is outputted to an air compressor control circuit 10, and a compressor 14 is driven. When it is judged as unnecessary, a stopping command is outputted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device mounted on a remotely controlled vehicle, and is suitable for, for example, a wirelessly controlled diesel locomotive.

[0002]

2. Description of the Related Art Diesel locomotives often repeat running and stopping within a short distance during replacement work. Further, the diesel locomotive needs to supply a large amount of control air to the air brake control device which is the pneumatic device of the vehicle to be towed. Therefore, the diesel locomotive consumes a large amount of useless air. In such a case, the operator performs a quick-filling operation with an air compressor in order to quickly supplement the air in the air blunder.

Conventionally, a radio-controlled diesel locomotive (hereinafter, a “radio-controlled diesel locomotive” is referred to as a locomotive)
The control of the fast-forward operation was performed by the operator transmitting a wireless fast-forward command by operating the wireless transmitter or canceling it. Accordingly, a command control current flows or stops flowing from the locomotive side receiver, and a method of operating or deactivating the relay of the air compressor quick-load circuit has been adopted (for example, Japanese Examined Patent Publication No. 57-47058). . This method was effective for the pilot to operate the air compressor pre-loading operation of the locomotive from a distance from the locomotive.

[0004]

However, according to the conventional method, when the operator cannot separate the air damaging pressure of the locomotive when the operator moves away from the locomotive to operate the quick-load operation. , The following problems occur. If the command for wireless pre-loading is sent by the operator even if the air damaging pressure of the locomotive is above a predetermined value, the locomotive-side receiver will receive the command control current for pre-loading operation. It was sometimes output until it was canceled.

The problem to be solved by the present invention is that when the operator has difficulty grasping the air damaging pressure of the locomotive, the air damaging pressure is transmitted when the pilot sends a fast-forward command or cancels the fast-forward command. When the wireless fast-forward command is continued for an unnecessarily long time even if is above the predetermined value, or when the wireless fast-forward command is canceled when the air damaging pressure is less than the predetermined value without being grasped by the machine at the time of cancellation. Is to occur. Further, if any abnormality occurs in the locomotive, the pre-loading command may continue to be transmitted until the driver recognizes the information.

The present invention has been made in order to solve the above-mentioned problems, and when the operator sends a command to the locomotive to permit the quick-load operation, the control device must always perform the quick-load. Instead of outputting the operation start command to the air compressor control circuit, it is necessary to judge whether or not the quick-load operation is possible based on the command and information from various known detection circuits incorporated in the locomotive. Only in such cases, a command for starting or stopping the quick-load operation is output to the air compressor control circuit. In addition, if the pilot has stopped sending the command to allow the fast-forward operation, or if there is a detectable abnormality in the locomotive, and if the fast-forward operation is being performed, the fast-forward operation is promptly performed. An object of the present invention is to provide a control device that outputs a command to terminate to an air compressor control circuit.

[0007]

SUMMARY OF THE INVENTION The present invention is a control device for a remotely controlled vehicle (hereinafter, a "control device for a remotely controlled vehicle") having an air compressor for driving pneumatic equipment and an air dam. Therefore, based on the command information that permits the quick-load operation to perform high-speed air filling to the air dam by the air compressor and the information from various known detection circuits incorporated in the remotely controlled vehicle, the quick-load operation can be performed. It is a control device having a function of determining whether or not it is possible and outputting a start command or a stop command of a pre-load operation to the air compressor control circuit only when necessary.

[0008]

The control device for a remote-controlled vehicle according to the present invention is capable of performing a quick-load operation based on command information for permitting the quick-load operation by the operator and information from various known detection circuits incorporated in the remote-controlled vehicle. When it is determined that it is necessary, a command for starting the rapid loading operation is output to the air compressor control circuit. When it is determined that the fast-forward operation is not necessary, the fast-forward operation of the air compressor is controlled by outputting a command to stop the fast-forward operation to the air compressor control circuit only during the fast-forward operation. Is.

It is a calculation unit.

The electrical signals output by the various detection circuits described above are defined as follows. The electric signal 18 related to the command for permitting the quick-load operation is "1" if there is a command, and "0" if there is no command.
And The electric signal 19 from the pressure state detection circuit 6 of the air dam 15 is "1" when the air dam pressure is less than the set value and "0" when it is above the set value. The electric signal 20 from the stop state detection circuit 7 is "1" when the locomotive is stopped and "0" when the locomotive is running. The electric signal 21 from the locomotive abnormal state detection circuit 8 is set to "1" when the locomotive is judged to be normal, and to "0" when it is judged to be abnormal.

8 and outputs to the control device 5. The controller 5 determines the outputs from the various detection circuits including the electric signal 18 as follows. An electric signal 18 relating to a command for permitting the quick-load operation, an electric signal 19 from the pressure state detection circuit 6 of the air slack 15, an electric signal 20 from the vehicle stop state detection circuit 7, and an abnormal locomotive state detection circuit 8 When the electric signal 21 and the electric signal 22 related to the state of whether or not the wireless reception is normally performed are “1”, the comparison calculation unit 24 of the start condition of the quick-load operation outputs “1”. Furthermore, the result of the comparison operation part 24 of the start condition of the quick-load operation is “1” and the electric signal 2 from the quick-load state detection circuit 9 is obtained.
Only when 3 is “0”, the comparison operation section 25 for outputting the start command for the fast-load operation outputs “1”. The control device 5 outputs a command for starting the quick-load operation to the air compressor control circuit 10 only when the result of the comparison calculation unit 25 is “1”. This output time outputs a sufficient time (for example, 2 seconds) to operate the quick-load function that the locomotive has as a known function.
Therefore, the comparison calculation unit 25 for the start command output of the quick loading operation
The control device 5 does not continue to output the command for starting the fast-load operation to the air compressor control circuit 10 when the result of 1 is continuously “1”. After that, when the air damaging pressure reaches a predetermined value or more, the quick-filling operation is canceled by the reset operation function which the air compressor control circuit 10 has as a known function. For this reason, the operator does not need to be aware of the timing of the end of the early loading when the locomotive is transmitting the command to permit the early loading operation to the locomotive.

Next, a case will be described in which the control device 5 outputs a command to stop the fast-forwarding operation to the air-compressor control circuit 10 during the fast-forwarding operation by the air compressor 14. The comparison calculation unit 26 of the conditions for stopping the fast-forwarding operation determines whether or not the electric signal 18 relating to the command for permitting the fast-forwarding operation, the electric signal 21 from the abnormal locomotive state detection circuit 8, and the wireless reception are normally performed. If any of the electric signals 22 relating to the state is "0", "1" is output. Further, the result of the comparison calculation unit 26 of the stop condition of the quick-load operation is "1",
And the electric signal 23 from the early loading state detection circuit 9 is "1".
Only in the case of, the comparison calculation unit 2 for the output of the command to stop the fast-forward operation
7 outputs "1". The control device 5 outputs a command to stop the fast-forward operation to the air compressor control circuit 10 only when the result of the comparison calculation unit 27 is “1”. This output time outputs the time (for example, 1 second) that is sufficient for operating the fast-loading forced reset operation function provided in the locomotive as a known circuit as in the above case. As a result, the air compressor control circuit 1
The fast-forwarding operation is canceled by the forced reset operation function of the fast-forwarding operation that 0 has as a known function. Thus, the fast-forwarding operation can be stopped when the command to permit the fast-forwarding operation by the operator is stopped, when the locomotive abnormal state is detected, or when the wireless reception is not normally performed.

The present invention is not limited to the above embodiment, but is also suitable for a vehicle for remote control equipped with an air compressor for driving pneumatic equipment and an air dam.

[0014]

As described above, according to the present invention, the control device allows the operator to issue the command for permitting the quick-load operation transmitted from the wireless transmitter and the outputs from various known detection circuit units incorporated in the locomotive. Based on the information from the above, it is determined whether or not the quick-load operation is possible, and the start command or the stop command of the quick-load operation is output to the air compressor control circuit of the locomotive. Therefore, the operator does not need to operate the wireless transmitter while inferring the air pressure failure, which improves the operability. In addition, it is possible to quickly detect the early-loading start time with respect to the decrease in the air useless pressure, and it is possible to improve the efficiency of the fast-loading work of the radio-controlled vehicle.
