Abstract

PROBLEM TO BE SOLVED: To prevent mis-operation of a switch group and to execute resetting the switch group. SOLUTION: When a mis-operation preventing switch 13 is closed after a setting condition of the controller main body is finished by using flat panel switches 12a-12o, on/off of a switch group A desiring to fix a state of the setting end, for example, is invalidated and the switch group A keeps a state at the end of setting till the mis-operation preventing switch 13 is turned off. Furthermore, the control of a CPU provided to a control circuit is disable and when resetting is required once, a reset switch 14 is closed to initialize the setting of the flat panel switches 12a-12o and to conduct the setting again. When the mis-operation preventing switch 13 and the reset switch 14 are closed, LEDs 15, 16 are lighted or blinked to allow the operator to confirm the state externally.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for an optical space transmission device such as a controller for remotely controlling the optical space transmission device.

[0002]

2. Description of the Related Art FIG. 4 shows a perspective view of a system of a conventional optical space transmission apparatus, in which heads 1 and 2 for transmitting and receiving laser light are shown.
Controllers 3 and 4 for remotely controlling the heads 1 and 2 are respectively connected to. This controller 3
5, a flat panel 6 is provided on the control circuit 5 as shown in FIG. 5, and a flat panel 7 is also provided on the front surface of the controller 4.

FIG. 6 shows a front view of the flat panel 6,
The flat panel 6 is provided with, for example, 15 flat panel switches 6a to 6o for setting various conditions, and a power switch 8 is connected to the flat panel 6.

FIG. 7 shows a block circuit configuration diagram of the control circuit 5, in which input data from the flat panel switches 6a to 6o is inputted by the CPU 9 in the control circuit 5 and a control signal is sent to a not-shown optical space transmission apparatus main body. Is sent.

For example, assuming that the system on the transmitting side is the head 1 and the controller 3, and the system on the receiving side is the head 2 and the controller 4, all the video information obtained by the television camera and the communication data for data communication are once. It is input to the controller 3. The input transmission information is modulated by the modulation circuit in the controller 3 and sent from the head 1 to the head 2 by laser light. The transmission information received by the head 2 is output to the controller 4 and demodulated into an electric signal by a demodulation circuit in the controller 4.

The heads 1 and 2 for transmitting and receiving laser light are all set by the controllers 3 and 4. In the controller 3, after the power switch 8 is turned on, the flat panel switches 6a to 6o make the settings. The input data of the flat panel switches 6a to 6o is recognized by the CPU 9 and sends a control signal to the main body of the space optical transmitter (not shown).

[0007]

However, in the above-mentioned conventional example, since all the flat panel switches 6a to 6o other than the power switch 8 exist in a plane on the same plane, the respective flat panel switches 6a to 6o are arranged. At the same time as it has the advantage of being easy to push, there is a problem in that the flat panel switches 6a to 6o are erroneously pushed even after the setting is completed, and the setting of the switch group whose fixed setting state is to be fixed is changed. .

Further, when the CPU 9 becomes uncontrollable and the flat panel switches 6a to 6o are once reset, it is necessary to turn off the power source of the controller 3 once, turn on the power source again, and perform various settings again. For example, when the flat panel switches 6a to 6o and the power switch 8 are far from each other, the operator moves to the power switch 8 by himself or gives an instruction to another operator waiting near the power switch 8. It has to be taken out and the operability is poor.

An object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide a control device for an optical space transmission device, which is capable of preventing an erroneous operation and resetting the switch group by providing an erroneous operation prevention switch and a reset switch in the setting switch group.

[0010]

A control device for an optical space transmission apparatus according to the present invention for achieving the above-mentioned object is provided in a certain switch group among setting switch groups provided for setting various conditions. On the other hand, an erroneous operation preventing means for preventing erroneous operation after completion of various settings is provided.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 shows a side view of the embodiment, in which a flat panel 12 is provided on a control circuit 11. 2 shows a front view of the flat panel 12, on the flat panel 12, for example, 15 flat panel switches 12a to 12a for setting various conditions.
12o, an erroneous operation prevention switch 13, a reset switch 14, LEDs 15 and 16 are provided, and a power switch 17 is connected to the flat panel 12.

When the erroneous operation prevention switch 13 is turned on after various settings of the apparatus main body have been completed by using the flat panel switches 12a to 12o, for example, the switch group A after which the setting completion state is desired to be fixed is set. Switch on / off is disabled, and switch 13
Until the switch is turned off, the switch group A maintains the state when the setting is completed.

When the CPU provided in the control circuit 11 becomes uncontrollable and needs to be reset once, the reset switch 14 is turned on to initialize the settings of the flat panel switches 12a to 12o, and the settings are performed again. . When the erroneous operation prevention switch 13 and the reset switch 14 are turned on, a control signal is output from the control circuit 11 to turn on or blink the LEDs 15 and 16 so that the operator can confirm from the outside. In addition,
Instead of displaying with the LEDs 15 and 16, this confirmation method may be another method such as generating a sound or vibrating a part or the whole of the controller.

In this manner, it is possible to prevent erroneous operation and reset any switch group, and it is also applicable to the case where the switch group is a push button switch or toggle switch other than the flat panel. it can.

FIG. 3 is a perspective view of another embodiment. The flat panel 21 can be attached so as to be covered with, for example, a box-shaped lid 22, and a power switch 23 is connected to the flat panel 21. ing.

If the lid 22 is attached so as to cover the flat panel 21 after the setting is completed by the various flat panel switches on the flat panel 21, the flat panel switch is prevented from being touched by an object and the erroneous operation after the setting is completed. Can be prevented.

The lid 22 can have any shape other than the box shape, and if a transparent member such as acrylic is used for the material of the lid 22, the setting state of the flat panel switch can be set even after the lid 22 is attached. The operator can confirm.

[0018]

As described above, the control device for the optical free space transmission apparatus according to the present invention can prevent erroneous operation and perform reset for a certain switch group in the setting switch group, thus improving operability. can do.
