(12) and control of the voice control unit 16, and if the abnormality of the wireless communication module 12 is detected through the detection unit 14 generates a buzzer sound according to this to recognize the abnormal state of the device And control the device to be set and operated according to the input of the button unit 24, and present time and temperature through the clock display unit 20, the temperature sensor, and the display unit 22. It is configured to perform overall control for the operation of the radio receiving apparatus 10 provided in the remote announcement system according to the present invention, such as to be displayed.

In FIG. 2, reference numeral 30 denotes a power source to which external power is supplied for operation of the radio receiver 10, reference numeral 32 denotes a reset unit which is an initialization button of the device, and reference numeral 34 denotes an RTC which is a real time clock. Indicates.

Next, the operation of the present invention as described above will be described in detail as follows.

First, according to the present invention, the broadcasting device 100 is installed in a town hall used as a public place such as a farming or fishing village or a mountain village, and each wireless home of the village has a specific structure as described above. As the receivers 10 are installed, the remote announcement system is implemented.

      Therefore, the manager 200 such as the person in charge of the local government or the head of the village may perform a predetermined guide broadcast through the broadcasting apparatus 100. That is, the person in charge of the local government or the village director is provided in the broadcasting apparatus 100. A predetermined announcement can be made by using the telephone network 300 at a remote location through the broadcast broadcasting device 110, or a guidance announcement can be directly performed through a microphone (not shown) provided in the broadcasting device 100. It is.

      Thus, when the administrator 200 such as the person in charge of the local government or the village headman performs the predetermined announcement broadcast via the broadcasting apparatus 100, the corresponding broadcasting contents are provided with the amplifier 130 provided in the broadcasting apparatus 100 and At the same time, the broadcast contents are output as a voice signal through the speaker 132, and the broadcast contents are carried on a frequency of a specific channel through a wireless transmission device 120 composed of household radios. To the device 10 side.

      That is, the predetermined voice signal carried on a specific frequency through the radio transmitting apparatus 120 of the broadcasting apparatus 100 is transmitted through the antenna 12a of the radio receiving apparatus 10 provided in each home. And the corresponding voice signal transmitted to the wireless communication module 12 is output through the speaker 16a under the control of the control unit 36 and the voice control unit 16. The announcement can be delivered smoothly every time.

      At this time, the push to talk (PTT) button of the living radio constituting the wireless communication module 12 of the wireless receiving device 10 is arbitrarily operated, or the wireless communication module 12 and the control unit 36 are mutually When an abnormality occurs in the connecting cable to be connected, the detection unit 14 detects this and generates a buzzer sound, so that the user of each household can immediately check whether the wireless receiving device 10 is abnormal.

      That is, the connection cable inserted into the earphone terminal of the wireless communication module 12 outputs a voltage of about 3 volts [V]. At this time, the connection cable is misinterpreted or omitted, or the wireless communication module 12 If the PTT button is pressed arbitrarily, the output voltage of the connection cable drops to about 1 volt [V].

      The detection unit 14 detects this and applies a signal corresponding thereto to the control unit 36. The control unit 36 outputs a buzzer sound according to an abnormality of the wireless communication module 12, thereby outputting the buzzer sound. As a result of the abnormality of (12), the problem that the predetermined guide broadcast from the remote broadcasting apparatus 100 cannot be delivered can be solved.

      On the other hand, the radio receiving apparatus 10 constituting the guide broadcasting system according to the present invention is provided with a clock display unit 20 is configured to display the current time, the broadcasting apparatus 100 in the radio transmitting apparatus 120 side The current date and time data consisting of DTMF tones are carried on the corresponding frequency periodically and the control is made so that the control unit 36 of the wireless receiving apparatus 10 receives the date received through the wireless communication module 12. And the current time displayed on the clock display unit 20 is periodically updated based on the time data.

      Therefore, the clock display unit 20 of the wireless receiving apparatus 10 is able to be accurately set the current time always without a separate operation of the user.
