Abstract

Disclosed is a system for conveying and announcing an emergency message with radios, which provides a broadcast system to be set up in a building, a community, or a public place such as an organization or a school. An emergency receiving device combines at least one radio receiver unit to receive an emergency event message transmitted from a public channel or an on-site channel in radio frequency and incorporates a speech amplifier to amplify and broadcast a voice signal to announce the emergency message to people within the area.

Claims

1. A system of the broadcast for transmitting emergency message using a radio device, the system comprising a plurality of emergency receiving devices distributed in a building or a given area and at least one voice transmitting device, wherein

the emergency receiving device comprises at least one radio receiver unit and a speech amplifier, the radio receiver unit setting up at least an address code and a radio channel, in which a voice message is transmitted from the voice transmitting device and received by the radio receiver unit and is then subjected to signal amplification by the speech amplifier to be broadcast by a speaker connected to the speech amplifier in a voice form to be heard by the public;

and

the voice transmitting device comprises at least one radio transmitter unit, in which an RF transmitter of the radio transmitter unit transmits a voice signal of the voice message to the emergency receiving device.

2. The system according to claim 1, wherein the address code of the radio receiver unit comprises at least a common address code.

3. The system according to claim 1, wherein the address code of the radio receiver unit comprises a dedicated address code and at least a common address code.

4. The system according to claim 1, wherein the address code of the radio receiver unit comprises coding indicating at least one of a district, a street, a building floor, and a serial code of receiving device in the same floor.

5. The system according to claim 1, wherein the receiving channel of the radio receiver unit comprises one or more public channels.

6. The system according to claim 5, wherein the receiving channel further comprises an on-site channel.

7. The system according to claim 5, wherein the public channel comprises a channel of police system or NOAA emergency broadcast system.

8. The system according to claim 1, wherein the emergency receiving device further comprises with an emergency lighting unit connected with radio receiver unit by a control circuit;

the emergency lighting unit comprising a lighting circuit that is composed of a charging circuit, a storage battery, a power supply circuit, and a light; and

the control circuit detecting if an AC power source is cut off and/or deciding if a message received by the radio receiver unit is an emergency message, whereby when the AC power source is cut off and/or the radio receiver unit receives an emergency message, the control circuit generates a control signal to automatically activate emergency lighting and supply electrical power for lighting and broadcasting.

9. The system according to claim 8, wherein the radio receiver unit and the speech amplifier of the emergency receiving device are connected to the control circuit so as to perform interrupting broadcast when the control circuit determines that a signal received by the radio receiver unit is an emergency message.

10. The system according to claim 1, wherein the voice transmitting device comprises any one of a regular voice transmitter, a two-way radio, or a handset or in-car device of a police system.

11. The system according to claim 10, wherein the voice transmitter or the two-way radio is connected to an on-site control center in a wired manner.

12. The system according to claim 11, wherein the on-site control center is connected through a network to other control centers for operation.

13. The system according to claim 11, wherein the on-site control center sets up a receiving circuit dedicated to receiving an NOAA channel.

14. The system according to claim 1, wherein the emergency receiving device further comprises setting a message of GPS geographic coordinate code in the radio receiver unit and comprises a transmitter connected to the radio receiver unit for responding to a calling request from a voice transmitting device.

15. The system according to claim 14, wherein an Ack message returned by the transmitter comprises the message of at least a GPS geographic coordinate code.

16. The system according to claim 1, wherein the emergency receiving device further comprises a display connected to the radio receiver unit to display an emergency message that is transmitted as a text message.
