Abstract

PROBLEM TO BE SOLVED: To conduct various control such as zooming and turning of remote control camera equipment at a remote location through the use of a digital portable telephone line. SOLUTION: A remote control camera equipment 6 incorporating a digital portable telephone set 7 is installed at an unattended site at a remote location. A controller side personal computer control terminal equipment 1 is operated to call the digital portable telephone set 7 at site. When a telephone line is connected, an exclusive transmitter sends a video and audio signal of the remote control camera equipment 6 to the controller side. The controller side conducts required control through the digital portable telephone line 5 while viewing the video image.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of using a digital portable telephone line as a control signal line of a remote control camera device installed in an unmanned field.

[0002]

2. Description of the Related Art For remote control of a conventional remote control camera device, a dedicated operation box is provided on the control side, and a control signal is sent to the remote control camera device through a general public telephone line or a dedicated telephone line installed up to the site. Had control. Therefore, even if a remote control camera device is installed in an emergency and a video is taken, a temporary telephone line up to the site must be laid in advance as a control signal line. It was not suitable for measures such as continuous monitoring. Also, even if a telephone line is installed, the control side must operate with a pair of remote control camera and dedicated operation box.
It was complicated.

SUMMARY OF THE INVENTION The present invention overcomes the drawbacks of digital portable telephones, which have recently become popular rapidly. This phone
Since it is a wireless system and the transmission speed is high, and it is a digital system, it was found to be excellent in terms of line stability and reliability. For this reason, how to operate a digital mobile phone that is usually operated by humans to make a call, send a fax, and load data into a personal computer.
The research was carried out by setting it up in an unmanned place and stably transmitting and receiving control and monitoring data between the control side and the remote control camera device and improving operability.

[0004]

[Means for Solving the Problems] In order to construct a control signal line by making a call by connecting to a digital portable telephone set in an unmanned place, 1. A microcomputer board is built into the local remote control camera controller. The program on this board performs a corresponding operation according to a control signal from the control side. 2. Since the site is a microcomputer, the control side will naturally be a personal computer device with a CRT screen. The operator calls the digital mobile phone by executing the control command displayed on the CRT screen. 3. The local microcomputer board called from the personal computer control terminal on the control side through the digital mobile phone line, if it recognizes that the other party is its own control side, it operates as instructed by the control side, and as a result Is returned to the control side. As mentioned above, once the digital mobile phone line is built,
Video and audio from the remote control camera device are sent to the control side using a dedicated transmission device. On the control side, the image sent from the site and the control result data sent from the digital mobile phone line are displayed on the same CRT screen. The operator sends the next instruction to the site while watching the image and the control result data. By constructing such a control loop, a reliable and stable remote control method for the remote control camera device has been discovered.

[0005]

With the above-described structure, the present invention can quickly control an unmanned site without laying a telephone line even in the event of an image transmission using a remote control camera device in an emergency. You can build a line. Further, since the control can be continued while displaying the camera image on the CRT screen of the control side personal computer, there is an effect that a response operation faithful to the intention of the operator can be performed.

EXAMPLES Two examples will be given as examples of the present invention. Embodiment 1 FIG. For the telephone line on the PC control terminal side, use a general subscriber telephone line. The local handset on the remote control camera device side will be a digital mobile phone. In this case, the line from the control side to the telephone station is a general subscriber telephone line, and the line from the telephone station to the remote control camera device side is a digital mobile telephone line. Embodiment 2. FIG. The telephone set on the personal computer control terminal side is a digital mobile phone. The phone on the local remote control camera side will also be a digital mobile phone. In this case, all lines between the control side and the local side are digital mobile phone lines. 1 above
In this case, since the local digital mobile phone is installed in the metal casing, radio waves are blocked and weakened, and the line may be disconnected. In this case, an external antenna is coupled to the antenna attached to the digital mobile phone, and this antenna is extended outside the housing. In the case of 2, in addition to this, the digital mobile phone on the personal computer control terminal side can also perform stable transmission / reception by extending the external antenna inside the building or pulling it outside the building.

[0007]

According to the present invention, with the above-mentioned structure, it is possible to perform lifeless video relay from mountainous areas where it is difficult to lay telephone lines, coasts, and scenic spots. Further, since it is sufficient to configure the digital mobile phone line only when control is required, the phone line charge can be reduced regardless of whether it is an urban area, a remote area or a remote area. Also, because the image of the remote control camera device can be displayed on the control side PC device screen, while watching the image of the control target, you can change the direction of the camera, zoom, turn on / off the power, connect the digital mobile phone line, etc. Various controls such as connection and disconnection can now be performed easily. In addition, since the control side uses a personal computer control terminal, the place where the terminal is installed is not limited, if there is a personal computer device,
It can be controlled from anywhere.
