Definitions

  • the present invention relates to remote operation of crane apparatuses used for, for example, unloading and loading of cargo, including containers, at docks for transport of the cargo.
  • crane apparatuses such as loading boats and ships or chassis with containers and unloading such containers from boats and ships or chassis.
  • RTG Rubber Tired Gantry Cranes
  • the method of driving this type of crane switches between manual driving and automatic driving. More specifically, in the case of a yard crane, loading onto and unloading from a chassis, serving as a container-transport truck, is carried out by manual driving. Loading onto and unloading from the chassis is carried out by manual driving as described above because it is difficult to correctly align the chassis with the yard crane. Furthermore, since the chassis is driven under the supervision of a person, the driver of the yard crane should preferably check that adequate safety precautions have been taken before handling containers. Other portions of the loading and unloading operations are basically performed by automatic driving.
  • Japanese Unexamined Patent Application Publication No. 5-246683 discloses the following method.
  • a plurality of cameras is installed on a trolley installed on a yard crane, video signals captured with these cameras are displayed on a monitor installed in a control tower by wirelessly transmitting the video signals to the control tower, and an operator remotely operates the yard crane while viewing the images displayed on this monitor.
  • Japanese Unexamined Patent Application Publication No. 2004-123367 discloses a technology for allowing a single operator to operate a plurality of cranes by receiving video signals from the plurality of cranes and automatically switching among images displayed on a monitor according to the operational states of these cranes.
  • the present invention has been conceived to overcome the above-described problem, and it is an object of the present invention to provide an apparatus for remotely operating a crane apparatus, a crane apparatus, and a system for remotely operating a crane apparatus capable of ensuring the prevention of mismatching between a yard crane that sends a video image displayed on a monitor and a yard crane to be remotely operated.
  • the present invention employs the following solutions.
  • a video signal showing a loading and unloading state transmitted from a crane apparatus is received by the reception unit and is displayed on the display unit as an image.
  • the operator since the first identification information of the crane apparatus that has sent the received video signal is displayed in part of the image displayed by the display unit, the operator can easily confirm whether the first identification information displayed on the display screen matches second identification information of the crane currently being remotely operated. As a result, mismatching between the crane apparatus that has sent the image displayed on the display screen and the crane apparatus to be remotely operated can easily be eliminated.
  • the above-described remote-operating apparatus preferably further includes a remote-operating unit configured to issue an operation command to one of the crane apparatuses to be operated; a comparison unit configured to compare the first identification information of the crane apparatus displayed on the display unit with the second identification information of the crane apparatus to be operated; and a report unit configured to report a result of the comparison.
  • this structure includes the comparison unit configured to compare the second identification information of the crane apparatus to which the operation command is issued from the remote-operating unit with the first identification information of the crane apparatus displayed on the display unit, mismatching between the crane apparatus that has sent the image displayed on the display unit and the crane apparatus to be remotely operated can be detected automatically. Furthermore, the report unit configured to report a comparison result allows the operator to easily check whether mismatching has occurred. As a result, not only can the workload imposed on the operator be reduced, but also mismatching can be detected more reliably.
  • the above-described remote-operating apparatus preferably further includes a remote-operating unit configured to issue an operation command to one of the crane apparatuses to be operated; a comparison unit configured to compare the first identification information of the crane apparatus displayed on the display unit with second identification information of the crane apparatus to be operated; and an operation-disabling unit configured to disable a remote operation by the remote-operating unit if the first identification information does not match the second identification information as a result of the comparison.
  • this structure includes the comparison unit configured to compare the second identification information of the crane apparatus to which the operation command is issued from the remote-operating unit with the first identification information of the crane apparatus displayed on the display unit, mismatching between the crane apparatus that has sent the image displayed on the display screen and the crane apparatus to be remotely operated can be detected automatically. Furthermore, since a remote operation by the remote-operating unit is disabled by the operation-disabling unit if the first identification information does not match the second identification information as a result of the comparison, a crane different from the one displayed on the monitor is prevented from being operated.
  • operation-disabling unit and the report unit may be combined.
  • the first identification information of the crane apparatus that has sent the received video signal is preferably superimposed on the received video signal.
  • the first identification information of the crane apparatus that has sent the received video signal is superimposed on the received video signal as described above, the first identification information of the crane apparatus can easily be acquired and displayed.
  • the comparison unit provided in the remote-operating apparatus preferably acquires the first identification information of the crane apparatus that has sent the received video signal by extracting the first identification information superimposed on the received video signal. As a result, the first identification information of the crane apparatus that has sent the video signal displayed on the display unit can be acquired easily.
