With reference to fig. 3, in an embodiment, the step S101 includes the following steps:
s10, the sensing unit acquires indoor sound data and sends the sound data to the processing unit;
s11, the processing unit converts the acquired sound data into decibel value data, judges whether the decibel value data exceeds a decibel value threshold value or not, and sends an abnormal signal to the communication unit if the decibel value data exceeds the decibel value threshold value;
s12, the communication unit receives the abnormal signal and sends the abnormal signal to the server.
In this embodiment, the sensing unit collects indoor sound, and sends generated sound data to the processing unit according to a preset time, for example, after sound within 10s is collected, sound data is sent to the processing unit once, the processing unit receives the sound data and converts the sound data into decibel value data, and then, the decibel value data is judged, it should be understood that one decibel value data is composed of a plurality of decibel values, specifically, whether a decibel value of the decibel value data exceeds a decibel value threshold value is judged, for example, the decibel value threshold value is set to 80, if a decibel value exceeds the decibel value threshold value, it is judged that someone in a room is quarreling, and an abnormal signal is generated and sent to the communication unit; and the communication unit receives the abnormal signal and forwards the abnormal signal to the server.

The application method of the Internet of things-based host pipe safety early warning system according to claim 5, wherein the processing unit converts the acquired sound data into decibel value data, judges whether the decibel value data exceeds a decibel value threshold, and sends an abnormal signal to the communication unit if the decibel value data exceeds the decibel value threshold, and the method comprises the following steps:
receiving sound data transmitted by the sensing unit;
dividing the sound data according to a time sequence to obtain a sub-sound data set;
selecting sub-sound data in the sub-sound set based on a preset sampling rule;
calculating each selected sub-sound data to obtain corresponding decibel value data;
and judging whether each decibel value data exceeds a decibel value threshold value or not, and if the current decibel value data exceeds the decibel value threshold value, sending an abnormal signal to the communication unit.
7. The application method of the Internet of things-based hosting safety precaution system according to claim 6, wherein after the sending the decibel value data to the communication unit, the method comprises:
if the current decibel value data does not exceed the decibel value threshold, continuing to judge whether the next decibel value data exceeds the decibel value threshold;
and deleting the current sub-sound data set after judging that all the decibel value data do not exceed the decibel value threshold value.
8. The application method of the internet of things-based host management safety early warning system, according to claim 6, wherein if the current decibel value data exceeds a decibel value threshold, sending an abnormal signal to the communication unit includes:
if the current sub-decibel value data exceeds the decibel value threshold, reading and traversing each sub-decibel value data in the corresponding sub-sound data set, judging whether the sub-decibel value data exceeds the decibel value threshold according to a time sequence, and if the current sub-decibel value data exceeds the decibel value threshold, recording;
and after judging all the sub-decibel value data, judging whether the total recorded times are greater than a preset recording time threshold value, and if the total recorded times are greater than the preset recording time threshold value, sending an abnormal signal to the communication unit.
9. The method for applying the internet of things-based host safety warning system according to claim 8, wherein the step of, if the current decibel value data does not exceed a decibel value threshold, performing:
judging whether the current decibel value data is 0 or not, if so, sending fault information to the server, and enabling the server to send a fault signal to the alarm terminal based on the fault information.
10. The method for applying the internet of things-based hosting safety precaution system according to claim 8, wherein the precaution system is the internet of things-based hosting safety precaution system according to claim 3, the method further comprising:
the server sends a shooting request to the corresponding camera terminal based on the received position information;
the camera terminal responds to the shooting request to obtain image data and returns the image data to the server;
the server receives the image data and sends the image data to the alarm terminal;
and the alarm terminal receives and displays the image data.
