Abstract

PURPOSE:To increase a TV camera, etc., and to execute a universal head control which abounds in extensibility by assigning an address to one of a control part and a universal head part, and also sending out a control signal to a data line. CONSTITUTION:A signal stored in advance for a universal head 2 is selected and generated by a command signal generating means 5 by pushing a switch for selecting the universal head of a selecting means 4. The signal from the means 4 is encoded by a means 13, is outputted as an ID signal of the universal head 2 from a control device 1', and is applied to code discriminating means 11, 11' of each universal head part A', B'. Also, a universal head 2 command signal from the means 5 is supplied to latching circuits 12, 12' of the universal head parts A', B'. Subsequently, a signal stored in advance in the latching circuit 12 is selected and applied to a driving device 3, and the universal head 2 is operated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pan head control device, and particularly to a cloud head control device for remotely controlling a television camera.

Generally, at television broadcasting stations, when the subject of news, weather reports, interviews, educational programs, etc. does not move much, the operator does not operate the TV camera, that is, the camera platform control device. The movement and stop positions of the TV camera in the horizontal direction (hereinafter referred to as ν down pan), vertical direction (hereinafter referred to as tilt), zoom, focus, camera height, etc. are stored in advance, and the operation Φ is controlled from the monitor room. are doing. In addition, if a plurality of television cameras are installed in the studio, the same number of control devices as the television cameras may be installed, or the pan head selection-p stage 4. A control device l consisting of a command signal generation f stage 5 and a demultiplexer 6,
Each TV camera head 2. - Connected to pan head sections A, B, and C, each consisting of pan head drive unit H3. Therefore,
In a conventional television camera pan head control device, the output section of the demultiplexer 6 of the control device l is connected to each pan head section A, B, and C.
Since the number of TV cameras exceeding the division capacity of the demultiplexer 6 is installed, the demultiplexer 6 must be changed, and the control unit l
The number of output connectors must be equal to the number of television cameras, which has the drawback of poor expandability when increasing the number of television cameras.

An object of the present invention is to eliminate the above-mentioned drawbacks, and a schematic configuration for realizing this object includes a pan head control device comprising one or more pan head control sections, and one or more pan head sections. One of the pan head units is selected by assigning a coded address to at least one of the pan head control unit and the pan head unit, and the control signal of the control unit is
output through a data line commonly connected to the pan head and output to the selected pan head;
When increasing the number of TV cameras and pan heads, there is no need to change the demultiplexer, change the wiring, or add parts to the existing parts.
Enables highly expandable pan head control.

An embodiment of the present invention will be described below with reference to the drawings. Second
The figure is a block circuit diagram of an embodiment of the present invention.

The control device 1' includes a pan head selection means 4, an ID encoding means 13 for encoding a signal from the pan head selection stage 4, and a command signal generation means 5 for selecting and instructing a pre-stored operation of the television camera. The pan head parts A' and B' are IDs of the television camera pan head 2, pan head drive device 3, and control device 1', respectively.
ID code discriminating means 11 for discriminating the signal from the encoding means 13; and a latch circuit 1 for latching the signal from the command signal generating means 5 based on the signal from the ID code discriminating means 11.
Consists of 2.

The operation of this embodiment of the present invention will be described below with reference to FIG. When operating the pan head 2, the operator presses a switch (not shown) for selecting the pan head 2 on the pan head selection means 4,
Further, the command signal generating means 5 selects and generates a signal stored in advance for the pan head 2. The signal from the pan head selection means 4 is encoded by the ID encoding means 13 and sent to the pan head 2.
The ID signal is outputted from the control device 1' as an ID signal, and is outputted to the ID code determination means 11, 11' of each pan head section A', B' (hereinafter, added pan head section). Furthermore, command signal generation 1
The 5th stage pan head 2 command signal is output to the latch circuits 12 and 12' of the pan head sections A' and B'. In this case, the ID code determination means 11 of the pan head section A' detects the pan head 2 ID signal and opens the latch circuit 12, so that the pan head 2 of the control section 1'
The command signal is selected from a signal stored in advance in the latch circuit 12 and is manually applied to the pan head driving device 3 to operate the pan head 2.

In the embodiment described in L, the pan head ID signal and the pan head command signal of the control section 1' are output in parallel to each pan head section, but the control section 1'
If the signal is converted into a serial signal using the step 1, it is possible to connect the control unit and each pan head unit with a single signal line.

Furthermore, in the above embodiment, a plurality of pan head units are controlled by one control unit, but the ID encoding means of each control unit to which the coded address is assigned is used to determine the ID code of each pan head unit. By connecting means, it is also possible to install a plurality of control sections and select these control sections to control one or more pan head sections.

In addition, in the above embodiment, if the logic section of the control section is made into a microcomputer, it becomes possible to add television cameras and pan heads by simply changing the software.

As explained above, by assigning an address to at least one of the control section and the pan head section, one of the pan head sections is selected, and the control signal of the control section is transmitted to the pan head section that is commonly connected to the pan head section. By outputting data through the same data line, the demultiplexer σ is
There is no need to change or change the wiring, and it has the effect of enabling highly expandable pan head control. Furthermore, if the logic section of the control section is made into a microcomputer, it is possible to add television cameras and pan heads simply by changing the software.
