Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control platform and a platform operating section used in a broadcasting station or the like.

[0002]

2. Description of the Related Art Conventionally, this type of remote control platform has been set in accordance with the installation location and the specifications of the department in charge of operation, and the program of the arithmetic circuit is used for the panning and tilting direction and range of tilting of the remote control platform. Has been changed to correspond. In addition, the turning operation directions of panning and tilting of the platform operation unit are individually addressed by changing the program of the arithmetic circuit or changing the polarity of the wiring of the member that operates panning and tilting.

With the recent miniaturization of television cameras,
Since it has become possible to design a remote-controlled platform with a TV camera in a small size, its applications have expanded and various specifications have emerged according to the installation environment. These specifications include
In order to prevent the TV camera from touching the wall when the remote control platform is hung from the ceiling, the TV camera is mounted in the opposite direction, or when the remote control platform is swung, There are cases where restrictions are required. In particular, with regard to hanging, this kind of small platform can be changed so that it is installed in a suspended state on the ceiling or the like by mounting the L-shaped supporter holding the TV camera with the mounting position shifted by 180 degrees. It is structured.

For this reason, it is necessary to reverse the turning direction with respect to the command signal, and to individually control the turning angle. For example, with respect to the turning direction, the following states can be considered in addition to the standard state. First, if the pan head is installed normally and the TV camera is installed upside down, the tilting direction must be reversed. If the pan head is installed in a suspended state, panning is necessary. It is necessary to reverse the turning direction of. Further, when the pan head is installed in a suspended state and the TV camera is attached backward and forward, it is necessary to reverse the turning directions of panning and tilting.

Further, there is a case where the above-mentioned specification change occurs due to the change of the installation place of the pan head or the layout of the studio after the delivery, and it is necessary to remodel the pan head accordingly.

There is also a problem of the habit of the operator who operates the platform operating section. For example, regarding the operation of tilting, when operating the operating member in the upward direction, the operator who wants the pan head to move upward and the operating member in the upward direction like a cameraman experienced person operate. Then, there is an operator who wants the pan head to move downward.

This depends on whether the moving direction on the television screen and the operation direction of the camera platform are the same, or the operating direction of the television camera is the same as the operating direction of the camera platform. Normally, the TV camera is operated behind the TV camera, so the image on the TV camera moves downward when it is lifted upward.Therefore, the movement direction on the TV screen and the platform operation direction are different for the TV camera. It is the opposite. The same applies to the panning operation.

Regarding the restriction of the turning angle, it is required that the setting value can be easily set, and the set value does not change even when periodical repair, disassembly and repair, or replacement of the printed circuit board. In particular, for broadcast pan heads, the technicians of their own stations respond in an emergency, so this demand is increasing.

[0009]

However, in the above-mentioned conventional example, when reversing the turning directions of panning and tilting, the program of the arithmetic circuit in the remote control platform or the platform operating section and the polarity of the wiring are changed. Must be done, and its configuration is not easy. In particular, when changing the turning direction according to the habit of the operator, it is desirable to be able to operate from the platform operation unit, but conventionally, such a remote control cloud that can easily set the rotation direction from the platform operation unit. No stand is proposed.

Regarding the setting of the turning angle of the remote-controlled platform, there is one described in Japanese Patent Laid-Open No. 62-57371. Setting means for setting turning limit angle data in the memory and cancellation for releasing this setting. Since it is realized by the means, there is a possibility that the turning limit angle data stored in the memory at the time of overhaul or repair may be lost or may be canceled due to an operation error.

An object of the present invention is to solve the above problems,
Provides a remote control platform and platform operating unit that can set the swing direction and swing angle from both the platform and platform operating unit, and prevents the settings from being lost during repair or replacement of the printed circuit board. To do.

A panning selection member for changing the direction to turn in the opposite direction to the remote control signal, and a tilting selection for changing the tilting turning direction to turn in the opposite direction to the remote control signal. It is characterized in that the output with the member is connected.

A control signal is transmitted in a specific communication format to the remote control platform body 11 via 10. At this time, the arithmetic circuit 7 monitors the states of the signal inversion selection member 8 and the signal inversion selection member 9, and when the switches of these selection members 8 and 9 are in the inversion state, the arithmetic circuit 7 selects the selection members 8 and 9. The data designating the turning direction of panning or tilting corresponding to is converted to turn in the opposite direction.

On the other hand, in the remote control platform body 11,

Similar to the first embodiment, the arithmetic circuit 14 integrates the control signal transmitted from the camera platform operating section 1 to calculate the position signal. Here, the arithmetic circuit 14 calculates the position signal in the panning turning range. When the range set by the selecting member 31 and the tilting turning range selecting member 32 is exceeded, by not performing the integral calculation, even if a control signal is further transmitted, the remote-control pan / tilt head does not turn. 31, 32
