technical field

The utility model relates to the technical fields of disaster early warning, emergency broadcasting, safety precautions, fire protection engineering, etc., and is suitable for early warning of earthquakes, tsunamis, air raids, typhoons, debris flows, floods and other emergencies.

Background technique

At present, the country has established a national emergency center and opened a national radio station, which is mainly responsible for remote warning and notification of disasters. Compared with mobile communication and other means, the national radio station has the advantages of being fast and not easily damaged by the disaster itself.

Although the national radio station has certain disaster warning capabilities, it is usually received through individual terminal receiving devices such as radios, set-top boxes, and televisions. For most audiences, such terminal receiving devices are mostly turned off when not in use. Even if the power is turned on, it may not always receive the programs of the emergency broadcasting station. Therefore, in order to give full play to the potential of the emergency broadcasting, it is necessary to design a matching remote wake-up terminal, but there is no better solution or relative A mature product emerges. Therefore, the main solution used in some places is the set-top box or the loudspeaker of the village sound, but when the terminal equipment such as the set-top box or the village sound is not in use, most of them are powered off, and it is difficult to ensure normal power supply during use. , so they are often useless when disaster warning is really needed. Therefore, the effect of such programs is not significant. On this issue, the National Academy of Broadcasting Science also made the remote wake-up of the terminal a key breakthrough project to study.

Detailed ways

The utility model provides a remote wake-up system for disaster early warning emergency broadcasting, the system includes a transmitting device and a receiving device, the transmitting device includes a broadcast transmitter 10 and an alarm encoder 9; the receiving device includes a receiving device An emergency broadcast receiving unit 1 of information, an alarm decoding unit 2, a voice prompt storage unit 3, an audio amplification unit 5 and a password verification device drive unit 4, the emergency broadcast receiving unit 1 is connected to the alarm decoding unit 2, and the alarm decoding unit 2 is connected to the voice prompt storage unit 3, the voice prompt storage unit 3 is connected to the audio amplification unit 5, and the alarm decoder 9 is connected to the password verification device drive unit 4 at the same time.

As a further preference, the utility model also includes an AC-DC power supply or a backup battery.

The broadcast transmitter described in the utility model is mainly a medium wave transmitter but is not limited to a medium wave transmitter, and can be a short wave and FM transmitter.

A voice alarm prompt is solidified in the voice prompt storage unit 3 .

The alarm decoding unit 2 is capable of responding to special codes.

When in use, the utility model relies on emergency medium-wave broadcasting as a means of communication. When an alarm is required, the transmitting device sends a special code to make the receiving device respond, and in conjunction with the different codes used, calls the voice alarm prompt solidified in the voice prompt storage unit 3 in advance to realize the voice prompt while alarming.

The receiving device of the present utility model can also be called an early warning terminal, which can be coupled with the intrusion alarm system and the fire broadcast and elimination system commonly installed in most communities, as a community early warning response system, because the intrusion alarm and fire broadcast equipment are regularly maintained and Check that the supply of power is guaranteed, so this solution has a unique advantage in response.

Considering the situation of direct use by individual users, the utility model can be linked with the home intrusion alarm system, and can also be used independently. The early warning terminal can also be equipped with an independent power supply and backup battery system to realize independent alarm and voice prompts.

Comprise following steps when the utility model uses:

1. The alarm encoder 9 uses a special encoding protocol (such as DTMF encoding) to encode the alarm and set a certain encryption program. The medium wave transmitter 10 can be a national emergency broadcasting station. In order to ensure safety and correctness, the alarm code is sent 3 times .

2. The code used in this utility model should contain the following information, early warning area: national\provincial\city (county, district) level\township level\; early warning type: earthquake\tsunami\air attack\typhoon\debris flow\flood and Other emergencies, etc.; if there is still time after sending the alarm code signal, the national emergency broadcast can then be broadcasted to explain the reason for the early warning to the public;

3. The public uses the medium-wave emergency broadcast receiving unit 1 to receive the early warning code, and is equipped with a special alarm decoding unit 2 and a password verification device driver unit 4. When two of the three received warning codes are completely consistent, the password verification device driver Unit 4 can compare the area code of reception with the area code in the machine, and if it is consistent, the password verification device driver unit 4 can further check the early warning type, call the voice alarm prompt of pre-existing voice prompt storage unit 3 in advance, and let the audio amplification unit 5 (speaker) can hear the sound of voice alarm. When it is used independently in the family, the driver unit 4 of the password verification device can directly drive the siren 6 (12VDC) to alarm; when it is used as a community, the driver unit 4 of the password verification device will output Two switching values can be used as the input signal of the alarm zone and the start signal of the fire broadcast.

4. Input the above-mentioned switch value into the 24-hour defense zone of the intrusion alarm system, and then the alarm can be triggered. In addition, when receiving in a centralized manner in the community, the audio content of the national emergency broadcast can also be linked with the internal fire broadcast system of the community (or enterprise) out).
