The master station wireless transmission / reception device 4 performs processing such as specified amplification, frequency conversion, and demodulation, and reproduces the image data from the slave station 6. The image data is sent from the master station wireless transmission / reception device 4 to the monitor 2 to display an image to notify the user of the occurrence of an abnormality. When the user confirms the occurrence of an abnormality and determines that it is necessary to publicize disaster information, evacuation advisories, etc. to the residents, the master station radio transmitter / receiver 4, antenna 5 can be turned on by the microphone installed on the console 3. The voice is sent to the slave station 6 via the slave station 6, and the slave station 6 directly notifies the inhabitants by the trumpet speaker 9 via the antenna 7 and the slave station radio transmitter / receiver 8. Another embodiment of the present invention will be described with reference to FIG. FIG. 2 is a block diagram showing the configuration of a broadcast wireless system that is an embodiment of the present invention. The embodiment of FIG. 2 recognizes the occurrence of an abnormality by a sensor, as compared with the embodiment of FIG. 1 which performs image comparison recognition of the occurrence of an abnormality by the image processing unit. The components having the same reference numbers as those of the components described above have substantially the same functions and operations as those in the related art. In addition, 12 is a sensor. A sensor 12 is provided in the outdoor loudspeaker station 6 with a surveillance camera shown in FIG. Sensor 1
2 is responsive to disasters such as earthquakes, landslides, volcanic eruptions, etc., for example, reacts to abnormally loud sounds, abnormally loud vibrations, unusually strong light, or unusually hot heat The sensor can recognize the occurrence of an abnormality at the monitoring site. The sensor 12 is configured to respond to at least one of the above sound, vibration, light, heat and the like. When the sensor 12 recognizes the occurrence of an abnormality, it sends a detection signal to the slave station wireless transmission / reception device 8. Hereinafter, similar to the operation in the case where the image processing unit 11 of FIG. 1 is provided, the slave station wireless transmission / reception device 8 takes an image with the surveillance camera 10, subjects the obtained image data to the prescribed processing, and the antenna 7
To send to master station 1. The master station 1 receives at the antenna 5, performs the specified processing at the master station wireless transmission / reception device 4, and reproduces the image data. The reproduced data is sent to the monitor 2 and an image is displayed to inform the user of the occurrence of the abnormality. The user confirms the occurrence of an abnormality, and if necessary, sends a voice to the slave station 6 via the master station wireless transmission / reception device 4 and antenna 5 from a microphone or the like mounted on the console 3, and the slave station 6 uses the antenna 7 The trumpet speaker 9 directly reports to the residents via the station radio transmitter / receiver 8.
