F. Embodiment FIG. 1 is a block diagram showing an embodiment of the present invention. A
, B indicates the monitoring area block set in the monitoring area,
Sensors and television cameras are installed in this block, as shown in block A as a representative example. Sensors 1, . The abnormality detection signal of each sensor is taken into the sensor corresponding section 2, and the sensor corresponding section 2 sends the number of the sensor detecting the abnormality to the remote control section 3. The remote control unit 3 has relationship information between the sensor number, its sensor type, and the swing angle of the television camera 4.
The swing angle of the television camera 4 is calculated from the current direction position information, and the calculated value is sent to the television camera corresponding section 5.

The TV camera corresponding section 5 swings the TV camera 4 according to the swing angle signal, and sends out a lighting control signal to turn on the lighting switch, thereby enabling the TV camera 4 to take pictures of the location where the abnormality has occurred. do.

Further, the television camera corresponding section 5 generates a zoom control signal for zooming the television camera 4 in response to a remote control command from the remote control section 3.

On the other hand, the remote control unit 3 performs processing to obtain a line connection with the monitoring room terminal 7 via the line handling unit 6 by identifying the occurrence of an abnormality using the sensor number, and after setting the line, the line handling unit 6 and the transmission line 8 are connected to the exchange. 9, the transmission line 10, the line control unit 11, and the monitoring room control unit I3 in the monitoring room terminal 7 via the transmission line I2.
A control signal I, an ID number of the monitoring area, a sensor number indicating the location of the abnormality, and a sensor type signal are sent to the controller. Similarly, the video signal of the abnormality location started by the TV camera 4 is as follows:
The video signal processing unit 14 connects the transmission path 8. After video signal processing is performed to enable transmission of sufficient video information within a transmission speed of 10, etc., the video signal is sent to the monitoring room control unit 13 in the monitoring room terminal 7 via the remote control unit 3 together with the control signal ■. It will be done.

Next, the monitoring room control unit 13 uses the alarm generation unit 15 based on the ID number of the monitoring area sent from the monitoring area blocks A and B, as well as the sensor number and sensor type indicating the location where the abnormality has occurred.
generates an abnormality alarm. This abnormality occurrence alarm is generated by an alarm buzzer or a synthesized sound representing the abnormality content by a voice synthesizer. Further, the control unit I3 sends the ID number of the monitoring area to the management information storage unit I7 through the management information control unit 16, and compares it with the monitoring area identification ID number stored in the storage unit 17 to determine the floor plan associated with the ID number. Related information such as map/drawing information etc. is pulled out and displayed as an image on the display section I8. Subsequently, the control section I3 supplies the video signal photographed by the television camera 4 to the image signal processing section 19 based on the control signal (2), and the processing section 19 converts it into a video signal that matches the display method of the display section 20. The display unit 20 displays a situation image of the location where the abnormality has occurred.

Therefore, the monitor stationed in the monitoring room can display the image on the display unit 20 that displays the status of the abnormality location, and the display that displays various related information including map and drawing information such as floor plans of the abnormality location. By visually checking the image displayed on the unit 18, the situation at the location where the abnormality has occurred can be quickly and accurately grasped without operating the television camera 4. Also,
In order to understand the detailed situation of the location where the abnormality has occurred, the instruction unit 21
