Description
Technical Field
The utility model relates to an alarm system field especially indicates a novel alarm system.
Background
In scenes with people gathering (such as classroom class, meeting in meeting rooms and square holding activities), accidents sometimes occur, such as robbery events, and at the moment, alarm information needs to be sent for help; however, the existing alarm system is over-exposed in arrangement or over-exposed in use mode (such as sounding), so that the existing alarm system is easily discovered by a lawless person when in use, the help can not be successfully asked, and even the personal safety is easily endangered.
Therefore, how to send out the distress message in an emergency situation in a concealed and fast and effective manner is an urgent problem to be solved in the industry.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel alarm system, it can conceal and quick effectual distress message that sends.
In order to achieve the above purpose, the solution of the present invention is:
a novel alarm system comprises a wireless microphone, sound amplification equipment in wireless communication connection with the wireless microphone, video recording equipment in electric connection with the sound amplification equipment, and a background server in communication connection with the video recording equipment; the wireless microphone is provided with an alarm key; the sound amplification equipment is internally provided with an MCU (microprogrammed control unit) processor; when the alarm key of the wireless microphone is pressed down, the wireless microphone transmits an alarm signal to the MCU processor of the sound amplifying equipment in a wireless transmission mode, so that the MCU processor controls the video recording equipment to work, and then the video recording equipment records the video and transmits the image to the background server.
The novel alarm system further comprises an infrared transceiver, and the wireless microphone is in infrared wireless communication with the sound amplifying equipment through the infrared transceiver.
And the MCU processor of the sound amplification equipment is electrically connected with the video equipment through the relay control circuit.
And the MCU processor 2 of the sound amplification equipment adopts an STM32 singlechip.
The video equipment is in communication connection with the background server in a wired communication or wireless communication mode.
After the scheme is adopted, when the utility model works normally, the public address equipment receives the audio signal of the wireless microphone normally and produces sound according to the received audio signal; and work as the utility model discloses when meetting emergency, the personnel of the wireless microphone of use press the warning button of wireless microphone for a warning signal of MCU treater wireless transmission of public address equipment is given to wireless microphone, and then makes MCU treater control video recording equipment work, makes video recording equipment carry out the video recording and transmit the image to backend server, thereby reports to the police.
According to the above, the wireless microphone is arranged on the alarm button for alarming, so that the alarm button is good in concealment and easy to operate, and meanwhile, when the alarm is given, the video recording is carried out through the video recording equipment and the image is transmitted to the background server, so that the concealment of the alarm action is good; thus, the utility model discloses just can conceal and quick effectual distress message that sends.
Drawings
FIG. 1 is a schematic block diagram of the present invention;
fig. 2 is a schematic diagram of the relay control circuit of the present invention.
Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the specific embodiments below.
As shown in fig. 1 and fig. 2, the utility model discloses a novel alarm system, which comprises a wireless microphone 1, an audio amplifier 2 connected with the wireless microphone 1 in wireless communication, a video recorder 3 electrically connected with the audio amplifier 2, and a background server 4 connected with the video recorder 3 in communication; the wireless microphone 1 is provided with an alarm key 11; the sound amplification device 2 is internally provided with an MCU (microprogrammed control unit) processor 21; when the alarm key 11 of the wireless microphone 1 is pressed, the wireless microphone 1 transmits an alarm signal to the MCU processor 21 of the audio amplifier 2 in a wireless transmission manner, so that the MCU processor 21 controls the video recorder 3 to work, and the video recorder 3 records video and transmits the video to the background server 4.
The utility model discloses in, the utility model discloses a novel alarm system still includes infrared transceiver 5, and wireless microphone 1 carries out infrared wireless communication through infrared transceiver 5 and public address equipment 2.
The utility model discloses in, the MCU treater 21 accessible relay control circuit 6 of public address equipment 2 is connected with the 3 electricity of video recording equipment, and the MCU treater 21 of public address equipment 2 is through controlling relay control circuit 6 to whether control video recording equipment 3's work. The MCU processor 21 can adopt an STM32 singlechip.
The utility model discloses in, video recording equipment 3 accessible wired communication or wireless communication's mode and backend server 4 communication connection.
The utility model discloses a theory of operation does:
when the utility model works normally, the public address equipment 2 receives the audio signal of the wireless microphone 3 normally through the infrared receiver 5 and produces sound according to the received audio signal; and work as the utility model discloses when meetting emergency, the personnel of wireless microphone 1 of using press wireless microphone 1's alarm button 11 for wireless microphone 1 gives an alarm signal of MCU treater 21 wireless transmission of public address equipment 2, and then makes MCU treater 21 pass through the work of relay control circuit 6 control video recording equipment 3, makes video recording equipment 3 record a video and transmit the image to backend server 4, thereby reports to the police.
As can be seen from the above, the utility model arranges the wireless microphone 1 on the alarm button 11 for alarming, so that the arrangement of the alarm button 11 is good in concealment and easy to operate, and simultaneously, the utility model records the video through the video recording device 3 and transmits the image to the background server 4 when alarming, so that the concealment of the alarm action is good; thus, the utility model discloses just can conceal and quick effectual distress message that sends.
