When the operator performs a predetermined operation for operating the platform 4 with respect to the operating device 17 while referring to the image displayed on the monitor TV 16, the control unit 14 sends the control data corresponding to the operation to the modem. Output to 15.

The control data for operating the platform 4 is transmitted to the control unit 8 via the modem 15, the distributor 13, the coaxial cable 22, the distributor 10, and the modem 9. The control unit 8 operates the platform 4 according to the transmitted control data. As a result, the directions in which the IT V camera 1, the infrared camera 2, and the ultrasonic microphone 3 face are changed, and the monitoring area on site is switched.

Next, the transmission of images on the spot will be described. The ITV image signal from the ITV camera 1 is input to the switch 5 via the coaxial cable 18. The signal of the image showing the heat distribution by the infrared camera 2 is input to the switch 5 via the coaxial cable 19.

Next, the abnormality determination of the image, the temperature distribution, and the ultrasonic monitoring will be described. First, the abnormality is determined by the image taken by the ITV camera 1. That is, the ITV image of the monitoring area is displayed on the monitor TV 16 and is monitored by the operator (monitor). While observing the displayed image, the operator adjusts the direction in which the ITV camera 1 faces (monitor area), the angle of view such as zoom and focus from the operation device 17, and monitors the situation at the site.

Secondly, the abnormality is determined by the image showing the heat distribution taken by the infrared camera 2. Infrared image monitoring is automatically performed for preset camera angles of view. In other words, when the operation of the platform 4 is instructed and the preset angle of view is reached, the switch 5 automatically switches between the ITV image and the infrared image. The image processing device 12 performs image processing on the infrared image demodulated by the demodulator 11 when the infrared image is selected by the switch 5, and monitors the abnormality based on the heat distribution.

When an abnormality due to heat is detected, the information is displayed on the monitor TV 16 via the S / P converter, the modem, etc., and fixed on the screen. This allows the monitor to know from the monitor TV 16 that a thermal abnormality has occurred in the field. Then, when an instruction to switch the selected image to the ITV image is input from the operation device 17, the ITV image of the location where the thermal abnormality has occurred is displayed on the monitor TV 16. That is, it is possible to instantly confirm the location where the thermal abnormality has occurred by the ITV image.

Thirdly, the abnormality is determined by the ultrasonic waves collected by the ultrasonic microphone 3. The ultrasonic monitoring is always performed, and is automatically and sequentially performed with respect to a preset camera direction. That is, when the operation of the platform 4 is instructed and the directions of the ITV camera 1 and the infrared camera 2 are set in advance, the ultrasonic microphone 3 automatically collects ultrasonic waves.

An analog value of the collected ultrasonic wave is converted into a digital value by the A / D converter 7. The control unit 8 compares the threshold value (dB value) set in advance to determine whether or not there is an abnormality.

If the result of this determination is that there is an abnormality, that information is displayed on the monitor TV 16 via a modem or the like and is fixed on that screen. This allows the monitor to know from the monitor TV 16 that an abnormality has occurred in the field. Then, when an instruction to switch the selected image to the ITV image is input from the operation device 17, the ITV image of the location where the abnormal ultrasonic wave is generated is displayed on the monitor TV 16. In other words, the place where the abnormality has occurred can be instantly confirmed by the ITV image.
