To explain the various keys one by one, the zoom switch 9, focus switch 10, and iris switch 11 are used to adjust the angle of view, focal length, and aperture of the television camera 7, respectively. The auto iris switch 12 is used to automatically adjust the aperture.

The proportion switch 13 is used when manually operating the television camera 7 horizontally or vertically.
By operating any one of the buttons, the television camera 7 is rotated in a direction corresponding to the position of each button. The auto scan switch 14 is used to select either an automatic repeating operation or a manual operation for the camera rotary table 1, and by pressing the switch 14, pre-registered locations are automatically and sequentially displayed. Further, when the pressing operation is released, the camera rotating table 1 can be rotated manually using the proportion switch 13.

The three horizontal speed switches 15 are used to set the rotation speed in the horizontal direction when automatically operating the camera rotating table 1. Three types of rotation can be achieved by selecting and pressing one of the switches 15. You can select one of the speeds.

The two vertical speed switches 16 are used to set the vertical rotation speed when automatically operating the camera rotating table 1, and two types of rotation can be achieved by selecting and pressing one of the switches 16. You can select one of the speeds.

The four station switches 17 are used to set in advance a specific position (hereinafter referred to as home position) to be displayed on the television camera 7, or to call up that specific position as necessary.
It is possible to set the home position of 4 corresponding to 7. Further, an LED (light emitting diode) 18 is incorporated in the center of each station switch 17, and is turned on when an external sensor, which will be described later and is installed at each home position, outputs an emergency signal.

The emergent engine switch 19 is used to rotate the camera turntable 1 to the home position based on an emergency signal output by an external sensor, and when pressed, an LED 20 built into the center lights up. ing. Further, by releasing the pressing operation, it is possible to cancel the operation of the camera rotating table 1 due to the emergency signal output from the external sensor.

As shown in FIG.
Various keys are provided for use when setting automatic operation. To explain the various keys, the memory switch 22 is used to set each stop position during automatic operation, and by pressing the memory switch 22, operation data of the proportion switch 13, horizontal and vertical speed switches 15, 16, etc. will be stored in the RAM described later. will be registered. The two-stage memory mode switch 23a is used when setting the automatic operation in a plurality of modes and when selecting one of the two set modes, and by switching up and down, it switches between A mode and 8 modes. It is possible to select one of the following. Similarly, the two-stage teaching mode switch 23b is used to select either the automatic operation setting or the home position setting, and either can be selected by switching upward or downward.

The interval time dial 24 is used to set the stop time at each stop position during automatic operation, and by operating each three-digit dial 24, the stop time can be set in seconds.

The clear switch 25 is used to erase each set automatic driving mode.

Next, the electrical configuration of the remote control device for remotely controlling the camera rotating table 1 will be explained with reference to FIG. The output signals of each switch on the operation panel 8 are output to the transmitting side CPU 28.

A ROM 29 and a RAM 30 are connected to the sending CPU 28, and a program for operating the sending CPU 28 is stored in the ROM 29 in advance.
The receiving side CPtJ (described later) is configured to store each data for automatic operation set by each of the switches in the RAM 30.
The external sensors 31 connected to 33 are installed at the home positions set by the station switch 17, and for example, ultrasonic sensors, infrared sensors, etc. are used to detect abnormalities such as intruders entering the home position. When detected, an emergency signal is output to the receiving CPU 33.

The output signal of the transmitting side CPtJ28 is output to the modulation circuit 32a, which modulates the digital signal outputted from the transmitting side CPU28 on a predetermined carrier wave for transmission, and the output signal is transmitted to the signal line. At step 27, the signal is output to the demodulation circuit 32b built in the camera rotating table 1. The demodulation circuit 32b demodulates a digital signal by removing the carrier wave from the output signal output from the modulation circuit 32a, and outputs the demodulated signal to the receiving CPU 33. Therefore, the modulation circuit 3 in the control box 26
2a and a demodulation circuit 32b in the camera rotary table 1 constitute a modem.

A ROM 34 and a RAM 35 are connected to the receiving side CPU 33, and the ROM 34 stores in advance a program for operating the camera turntable 1 based on the output signal from the sending side CPU 28.
The output signal from 8 is temporarily stored, and this data and ROM
Based on the program stored in the receiving side CPU 33
is now working.

The output signal of the receiving side CPU 33 is output to the drive circuit 36. The drive circuit 36 includes a first step motor 3'7 for rotationally driving the horizontal rotor 4, a second step motor 38 for rotationally driving the vertical rotor 6, a focus adjustment motor 39 for the television camera 7, and an iris adjustment motor 3'. motor 40,
A zoom adjustment motor 41 is connected thereto.

Next, the operation of the remote control device for the camera rotating table 1 configured as described above will be explained.

Now, the operation for setting the desired automatic operation operation on the camera rotating table 1 will be explained according to FIG. 5. First, select either automatic operation mode A or B and turn the memory mode switch 23a. For example, when switching to A mode and releasing the pressed state of the auto scan switch 14, the sending side CPU 28 detects the release operation and performs 5TEP.
1. Hereinafter, 5TEP will be referred to as S), and if it is in the automatic operation state, stop it (S2). Next, in order to set automatic operation operation, switch the teaching mode switch 23b to the scan side and operate the clear switch 25 (S3
．． S4), the sending CPU 28 erases the A-mode automatic driving data stored in the RAM 30 and performs initialization (S5).

In this state, when the proportion switch 13 is operated to set the automatic operation data for reciprocating between points A and B at different speeds, the transmitting side CPU 28 transmits the - and second drive the step motors 37 and 38 of the proportion switch 13.
Rotate the TV camera 7 in the direction corresponding to the operation (
S6). In this way, while watching the monitor, rotate the TV camera 7 so that the desired point A is displayed, and if necessary, adjust the monitor image by operating the zoom switch 9, focus switch 1o1, iris switch 11, and horizontal speed switch. 15, select one and press it, set the desired stop time with the interval time dial 24, and then press the memory switch 22 (S7), the transmitting side cPU 28 rotates the television camera 7 to point A. The angle, rotation speed, stopping time at point A, etc. are stored in the RAM 30 (S8).

In order to set automatic operation from point A to point B, operate the proportion switch 13 in the same manner as described above, rotate the television camera 7 so that it captures point B, and select which horizontal speed switch 15 After selecting and setting the desired stop time with the interval time dial 24, press the memory switch 22, and the transmitting side CPtJ28
The rotation angle and rotation speed of the television camera 7 up to point B and the stopping time at point B are stored in the RAM 30. With this operation, the operation data setting work for automatic reciprocating operation between points A and B at different speeds while stopping at points A and B for a predetermined period of time is completed. In addition, the television camera 7 is at point A and B.
Regardless of the rotational path during point exploration, during automatic operation the robot moves linearly between both points, and the rotational speed in the vertical direction is calculated and stored based on the rotational speed in the horizontal direction. Thereafter, when the auto scan switch 14 is pressed (89), the automatic operation operation setting work is completed, and the transmitting side CPU 28 starts the automatic operation operation shown in FIG.

Also, to explain the procedure for setting multiple home positions, first press the auto scan switch 14 to stop automatic operation (81, 82), then switch the teaching mode switch 23b to the station side (S
3) The transmitting side CPU 28 is in a state where it can receive output signals from each switch, and operates the proportion switch 13 etc. to display the desired home position on the monitor (810). In this state, when any one of the station switches 17 is pressed and the memory switch 22 is pressed (S11.512), the sending CPU 28 stores the home position in the RAM 30 (813). By repeating such operations, up to four home positions can be set at arbitrary positions.

Next, a case in which the television rotating stand 1 is operated will be explained. Now, when the auto scan switch 14 is pressed (S1), the sending side CPU 28 performs automatic operation in either mode A or mode B selected by the memory mode switch 23a, as shown in FIG.
14, S15°516). Then, when any of the station switches 17 is pressed during automatic operation (815
), the transmitting side CPU 28 rotates the television camera 7 via the receiving side CPU 33 so as to display the home position corresponding to the station switch 17 (S17).
This state continues until the station switch 17 is released from the press.

Additionally, when the external sensor 31 detects an abnormality such as an intruder at any home position during automatic operation and outputs an emergency signal, the receiving side CPU 33 detects the signal (
816). Then, when the emergency switch 19 is pressed, the receiving side CPU 33 rotates the television camera 7 toward the home position where the emergency signal was output, and displays the home position on the monitor (818).
519), this state is maintained until the output of the emergency signal is stopped. Furthermore, if the emergency signal is output from the external sensor 31 and the emergency switch 19 is not pressed, the receiving side CPtJ 33 maintains the automatic operation of the television camera 7 while the corresponding station switch 17
<818.820).

As described above, in this remote control device, the control box 26 and the camera rotating table 1 are connected by a modem consisting of a modulation circuit 32a and a demodulation circuit 32b, and the signal line 2
Since the signal line 7 can be configured with two or three lines including the ground wire, the wiring work is extremely easy, and since it is hardly affected by noise, the signal line 27 can be extended up to about 20 km.

In addition, it is possible to set in advance automatic driving operation in multiple modes that automatically repeat multiple points and display it on the monitor, and it is possible to automatically operate according to the set mode, so the operator can remotely control the operation each time. There is no need to operate the device, and monitoring work can be easily performed using a monitor.

In addition, multiple home positions can be set in advance separately from the automatic driving mode, and by operating the station switch 17, the desired home position can be called up and displayed on the monitor with priority over automatic driving, so the specific home position set as the home position can be You can quickly display and monitor your location. Furthermore, if the emergent engine switch 19 is pressed, when an abnormality is detected at each home position by the external sensor 31 provided at each home position, the home position will be displayed on the monitor regardless of the operation of the station switch 17. Therefore, the occurrence of an abnormality can be quickly discovered, and if the pressure on the emergency switch 19 is released, automatic operation will continue even if an abnormality is detected at the home position, and the abnormality will be detected. The LED 18 of the station switch 17 corresponding to the home position is lit. Therefore, in addition to abnormalities such as an intruder, the external sensor 31
By releasing the pressure on the emergency switch 19 when an emergency signal is expected to be output, unnecessary interruption of automatic operation can be prevented.
You can check this with Dl8.

Effects of the Invention As detailed above, the present invention provides a remote control device for remotely controlling a camera rotating table that rotatably supports a television camera in horizontal and vertical directions using a control box.
If the operation mode is set in advance using the input means, the camera rotation table can be automatically operated according to the operation mode, so the camera rotation table can be automatically rotated and rotated at multiple points without requiring operation by a supervisor. If a specific home position is set in advance using the input means, that home position can be quickly monitored with priority over automatic operation by operating the command means. If an external sensor detects an abnormality at the same home position, the camera rotating table can be automatically rotated toward the home position, making it possible to reliably monitor abnormalities at the home position. When an emergency signal can be expected, the rotation of the camera rotating table due to the emergency signal can be disabled using the selection means, so it is possible to prevent interruption of automatic operation of the camera rotating table based on unnecessary emergency signals from external sensors. This provides an excellent effect in that the presence or absence of the emergency signal can be displayed on the display means.
