An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a video camera, which is installed at a position where the progress of construction work and the like can be effectively photographed by the camera platform 2 so that the photographing direction can be freely changed. The video camera 1 can perform a zoom operation in response to a control signal from a construction office, and has functions of auto focus and automatic aperture.

[0008] Reference numeral 3 denotes a wireless device, which can communicate with a wireless device 4 installed in a construction office near a construction site. When the office is away from the construction site where the video camera 1 is installed, or when it is difficult to lay a communication cable, the wireless multiplex communication by the wireless devices 3 and 4 is effective, but as shown by a virtual line. However, this does not prevent the use of the wired multiplexing method using the communication cable 5.

Reference numeral 6 denotes a control device provided in the construction office, which mainly includes a control circuit unit 7, an operation panel unit 8, and an image transmitting / receiving device 11. The control circuit unit 7 includes a CPU, and is connected to the wireless device 4, the monitor television 9, and an image recording device 10 such as a VTR.

As shown in the enlarged view of FIG. 2, the operation panel section 8 includes a shooting direction operation lever 12, a zoom operation button 13, a memory switch 14 for setting a management point, and a mode switching button. 15, a telephone line switch 16, a telephone push button 17, a transmission image selection button 18, a reception image selection button 19, and a switching button 20 for switching between a transmission image and a camera image for checking. An input terminal 21 for inputting an external video image, an input image switch 22 for inputting a camera image and an external video image,
A computer processing confirmation display lamp 23 and a telephone line connection confirmation lamp 24 are provided.

Reference numeral 25 denotes a control device provided in a remote office, which is the same as the control circuit unit 7, the operation panel unit 8, and the image transmission / reception device 11 of the control device 8 in the local construction office. Part 2
6, an operation panel unit 27 and an image transmitting / receiving device 28 are provided. 29 is a monitor television, and 30 is an image recording printer. Reference numeral 31 denotes a solar cell, which is used as a power source for the video camera 1, the camera platform 2, and the wireless device 3 when no power is available.

Next, the operation and operation of the above embodiment will be described. First, the camera platform 2 is operated by the shooting direction operation lever 12 so that the direction of the video camera 1 is directed to the management point of the building under construction, and the zoom operation button 13 is pressed to perform the first operation necessary for the management. Adjust the points to make them easier to see. This adjustment operation is performed while watching the image on the monitor television 9. After the first management point is adjusted, the first button of the plurality of memory switches 14 is pressed to store adjustment information such as the direction of the camera and zoom. The adjustment information is automatically stored in the control circuit unit 7 just by pressing the memory switch 14 once so that anyone can use it.

The above operation is repeated a required number of times, and several management points by the video camera 1 are determined.
Set by each memory switch 14. Note that a plurality of video cameras 1 can be installed at several places on the construction site, and their management points can be set by the memory switch 14.

After the setting of the management points is completed, the image of the necessary management points is automatically displayed on the monitor television 9 in real time simply by pressing the read button of the mode switching button 15 and then pressing the target memory switch 14. be able to. The management points can be partially or entirely reset by using a partial switching button or the entire switching button of the mode switching button 15.

The image photographed by the video camera 1 can be recorded not only on the monitor television 9 but also by the image recording device 10. If images of several management points are automatically recorded every day by the image recording device 10 sequentially and automatically at a time set in advance by a timer,
Automatic recording of the progress of construction work is possible and can be replayed whenever necessary.

The above operation is performed by the remote control device 2
5 can also be performed directly without the intervention of a local construction office person. That is, after the telephone line switch 16 is turned on, the telephone push button 1
7 to access the control device 6 of the construction office, and perform the same operation as described above.

In a remote image receiving operation, a high-quality image, a low-quality image or a recorded image is selectively received as a still image by a received image selection button 19 on the operation panel 27, and the monitor television 29 Or recorded by the image recording printer 30.

Further, the management point can be automatically received by calling the data of the memory switch 14 for setting the management point of the local construction office. When recording a received image, it is also possible to provide an image recording device in an office in a remote place and record it. Further, a recording printer may be installed in a local construction office to record images.

The input terminal 21 is an image input terminal for connecting an output terminal of an electronic still camera or a portable video camera and transmitting the image to a communication partner. The computer processing confirmation display lamp 23 lights up during the computer processing, and the telephone line connection confirmation lamp 24
This is a display lamp for confirming that the telephone line is connected.

[0020]

Advantages of the Invention 1) A video camera can be automatically operated by a computer, a plurality of management points can be automatically viewed without operating the camera, and the progress of construction work can be automatically monitored every day. You can get the material by recording on video. 2) In addition to the local office, the video camera of the local construction office can be directly operated without the need for the person in charge of the local office to view and monitor the image of the work situation at a remote location. 3) Video and electronic still camera images can be mutually displayed between the local office and the remote office to hold a technical meeting. 4) The progress of construction sites scattered all over the country can be grasped concretely even in remote locations by using images, and centralized management can be performed. In addition, images can be exchanged between offices using general subscriber telephone lines. A communication network for transmitting and receiving can be constructed.
