An NB-IoT communication module is arranged in the NB-IoT alarm and is in network communication with the cloud server; alarm information can be uploaded to a server platform (cloud) in time, the cloud monitors the alarm information in real time, unified processing and issuing of reported data are achieved, dangerous case position information and the like can be synchronously pushed to estate, fire protection, street offices, house owner users and the like according to preset requirements, and the purposes of rapid identification and response processing of dangerous cases are achieved. And the adopted NB-IoT communication module is low in power consumption, wide in coverage and stable and reliable in transmission.
