  The mounting table 10 accommodates such a remote control device 100. In the present embodiment, the mounting table 10 is provided in the cabin of the work vehicle, and as shown in the perspective view of FIG. A casing 20 on which the remote control device 100 is placed is provided.

  The casing 20 is formed in a box shape with an upper opening provided with a bottom surface portion 21, a front surface portion 22, a rear surface portion 23 facing the front surface portion 22, and both side surface portions 24 and 24 that make the front surface portion 22 and the rear surface portion 23 continuous. The

A plurality of sensors 30 are provided on the bottom surface portion 21 of the casing 20. In the present embodiment, the sensor 30 is configured by a sheet-like or plate-like proximity sensor that transmits an electric signal when an object comes in contact with and away from the object, and when the remote control device 100 is placed on the casing 20, the remote control device 100 is The sensor 30 detects that it is placed on the casing 20.

  An alarm device 40 is provided inside the casing 20 so as to be joined to the inner surface of the front portion 22 of the casing 20. The notification device 40 will be described with reference to the block diagram of FIG.

  As illustrated, the notification device 40 includes a control unit 41. A sensor 30 is connected to the control unit 41, and an electric signal a transmitted from the sensor 30 is input.

  The control unit 41 is connected to an ignition key 60 of a work vehicle. The ignition key 60 is configured to be switchable in four stages of lock, ACC (accessory), ON, and START, and is ignited to an ACC that supplies power to an electrical system such as an air conditioner in a work vehicle or a stereo set. When the key 60 is entered, power is supplied to the notification device 40 and the power is turned on.

  The control unit 41 is also connected to a power switch 61 that turns on or off a crane mounted on the work vehicle.

  The power switch 61 is configured to be switchable in two steps, ON and OFF. When the input is OFF, the power to the crane is cut off and the operation vehicle is turned off. The vehicle is ready to run. When the input is ON, the crane is energized to be in an operating state, while the work vehicle is in an inoperable state.

The ON / OFF of the input of the power switch 61 is correlated with the electric signal a input from the sensor 30 to the control unit 41, and the control unit 41 generates the electric signal x or the electric signals y ₀ and y _1. Is done.

  Specifically, in this embodiment, when the input of the power switch 61 is ON and the electric signal a is not input from the sensor 30, no electric signal is generated, but the input of the power switch 61 is ON. When the electrical signal a is input from the sensor 30, the electrical signal x is generated in the control unit 41.

On the other hand, when the input of the power switch 61 is OFF and the electric signal a is not input from the sensor 30, the electric signal y ₀ is generated in the control unit 41, and the input of the power switch 61 is OFF and the electric power is output from the sensor 30. When the signal a is input, the control unit 41 generates an electrical signal y ₁ .

  Further, the notification device 40 is connected to the control unit 41 via a blue light emitting diode 50a that is a first light emitter connected to the control unit 41 via a wiring 52, a wiring 53, and a branch line 53a branched from the wiring 53. And a speaker 51 connected to the control unit 41 via a red light emitting diode 50 b as a second light emitter, a wiring 53, and a branch line 53 b branched from the wiring 53.

The electric signals x and y ₁ generated by the control unit 41 are input to the light emitting diode 50a via the wiring 52, and the light emitting diode 50a is lit in blue. On the other hand, the electrical signal y ₀ that is generated by the control unit 41 is input to the light emitting diode 50b via the wire 53 and the branch lines 53a, is inputted to the speaker through the branch line 53b.

When the electrical signal y ₀ is inputted to the LED 50b, the light emitting diode 50b lights up red, when the electrical signal y ₀ is inputted to the speaker 51, the speaker 51 utters a speech.

  The voice uttered by the speaker 51 is a synthesized voice stored in the control unit 41 in the present embodiment. For example, there is a message for preventing misplacement of the remote control device 100 such as “no remote control is stored”. It is synthesized.

  In this embodiment, the mounting table 10 having such a configuration is provided in a room of a work vehicle. When the remote control device 100 is mounted, the operation unit 102 of the remote control device 100 is arranged as shown in FIG. It is accommodated in the casing 20 and placed in a state in which the grip portion 104 protrudes from the casing 20.

  Next, a method for using the mounting table 10 according to the present embodiment will be described.

  FIG. 4 is a flowchart illustrating a process for detecting whether or not remote control device 100 is mounted on mounting table 10 according to the present embodiment. As shown in the figure, first, when an operator gets on the work vehicle and the operator switches the ignition key 60 and puts the ignition key 60 into the ACC in step S1, power is supplied to the notification device 40 of the mounting table 10. It becomes energized.

  When power is supplied to the notification device 40 of the mounting table 10 and the power is in the energized state, when the power switch 61 is turned on in step S2, the crane is energized to be in an operating state, and the work vehicle cannot travel. It becomes.

  At this time, if the remote control device 100 is placed on the mounting table 10 and the sensor 30 detects that the remote control device 100 is placed in step S3, the electrical signal a from the sensor 30 is sent to the control unit 41. The electric signal x is generated by the control unit 41 after being input.

  In step S4, the generated electric signal x is input to the light emitting diode 50a via the wiring 52, and the light emitting diode 50a is lit in blue.

  On the other hand, when the remote control device 100 is not placed on the placement table 10 and the sensor 30 detects that the remote control device 100 is not placed in step S3, the control unit 41 receives the electric power from the sensor 30. The signal a is not input.

  By the way, in step S2, when the power switch 61 is OFF, energization to the crane is cut off and the vehicle is inactive, while the work vehicle can travel.

At this time, if the remote control device 100 is placed on the mounting table 10 and the sensor 30 detects that the remote control device 100 is placed in step S5, the electrical signal a from the sensor 30 is sent to the control unit 41. When input, the control unit 41 generates an electric signal y ₁ .

Electrical signals y ₁ generated in step S4, is input to the light emitting diode 50a via a wire 52, the light emitting diode 50a is turned blue.

On the other hand, in the case where the power switch 61 is turned off in step S2, the remote control device 100 is not placed on the placing table 10, and the remote control device 100 is not placed by the sensor 30 in step S5. When it is detected, electrical signal y ₀ is generated by the control unit.

Electrical signal y ₀ that is generated in step S6, are input to the light emitting diode 50b via the branch lines 53a branching from the wiring 53 and the wiring 53, the light emitting diode 50b is turned red.

Furthermore, the electrical signal y ₀ is the same step S6, are input to the speaker 51 via the branch line 53b branched from the wiring 53 and the wiring 53, the speaker 51 is not stored is "remote control in this embodiment ”

  As described above, according to the mounting table 10 of the present embodiment, when the ignition key 60 enters the ACC, power is supplied to the notification device 40 of the mounting table 10, and the power switch 61 that energizes the crane is input to OFF. When the sensor 30 detects that the remote control device 100 is not placed on the casing 20 when the work vehicle is ready to travel, the light emitting diode 50b is lit red in the vehicle interior of the work vehicle. And the speaker 51 utters a synthesized voice saying that “the remote control is not accommodated”.

  When the ignition key 60 enters the ACC and the power switch 61 is turned OFF, the work vehicle is in a travelable state, so that the remote control device 100 is not placed on the casing 20 at this time. There is a high possibility that the remote control device 100 has been left behind at the work site.

  As described above, in a situation where there is a high possibility that the remote control device 100 has been left on the work site, the fact that the remote control device 100 is not placed on the casing 20 causes the light emitting diode 50b to emit red light and sound from the speaker 51. Can be notified to the worker in the cabin of the work vehicle. Thereby, misplacement of remote control device 100 can be suppressed.

  On the other hand, when the ignition key 60 enters the ACC and the power switch 61 is input to ON, the work vehicle is in an inoperable state and the crane is energized and in an operable state. If the device 100 is not placed on the casing 20, there is a high possibility that the crane is operated by operating the remote control device 100.

  Thus, when it is assumed that the remote control device 100 is operated and the crane is being operated, it is considered that the operator is holding the remote control device 100, so that the notification device 40 of the mounting table 10 works. The person is not notified.

  Further, when the ignition key 60 enters the ACC and the power switch 61 is turned off, the work vehicle is in a state where it can travel and the power to the crane is cut off, so that it is in an inoperative state. If remote control device 100 is placed on casing 20, there is a high possibility that the operator is driving the work vehicle or is in the previous stage.

  Thus, when it is assumed that the operator is driving the work vehicle or is in the previous stage, when the remote control device 100 is placed on the casing 20, the remote control device 100 is misplaced. The light emitting diode 50a emits blue light so that it is properly placed on the casing 20 without any trouble, and can be notified to the worker in the cabin of the work vehicle.

  Alternatively, when the ignition key 60 enters the ACC and the power switch 61 is input to ON, the work vehicle is in an inoperable state and the crane is energized and in an operable state. If the device 100 is placed on the casing 20, there is a high possibility that the crane is in an unoperated state even if it can be operated.

  Thus, when the remote control device 100 is placed on the casing 20 in a state where the crane can be operated, the remote control device 100 can be appropriately attached to the casing 20 by causing the light emitting diode 50a to emit blue light. It is possible to notify the worker in the cabin of the work vehicle that it is placed.

  In particular, in the present embodiment, in a situation where there is a high possibility that the remote control device 100 has been left at the work site, the light is emitted from the speaker 51 in addition to the light emitting diode 50b emitting red light and visually informing. Since the voice is audibly notified, the misplacement of the remote control device 100 can be effectively suppressed.

  Such visual notification by the light emitting diodes 50a and 50b and auditory notification by the speaker 51 can be easily realized by the control unit 41 in the present embodiment, so that the structure can be simplified. At the same time, an increase in manufacturing cost is suppressed.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning of invention. In the above-described embodiment, the case where the sensor 30 is configured by a non-contact type proximity sensor has been described. However, for example, a load sensor that detects the presence / absence of an object by the load of the object may be used.

  In the above embodiment, the case where the sensor 30 is provided on the bottom surface portion 21 of the casing 20 has been described. However, for example, the sensor 30 may be provided on the both side surface portions 24 and 24, or alternatively, the bottom surface portion 21 and the both side surface portions 24, Each of 24 may be provided.

  In the above embodiment, the case where the light emitting diodes 50a and 50b and the speaker 51 are provided on the outer surface of the front portion 22 of the casing 20 has been described, but may be provided on the inner surface.
