when the module reads the instrument data in each T1 time period and the instrument has alarm information, the module starts to report immediately and sends the alarm information to the cloud; and pushing data to the App software of the mobile phone of the user after the cloud receives the alarm data, and displaying the alarm information on the App software to remind the user. For example: the user receives the relevant instrument and meter of water level measurement, when the water level exceeds the warning water level, the water level measurement instrument produces warning information, the NB wireless module reads the instrument data, and when the water level warning information is found, the report of the warning information is immediately started. After receiving the alarm information, the cloud end pushes the alarm information to an App of the client mobile phone, and the alarm water level information is displayed in App software.
As shown in fig. 4, when the operation of the meter fails or the meter detection data is abnormal, the alarm information is generated, the wireless communication module queries and acquires the alarm information, establishes wireless communication connection, reports the alarm data to the cloud, and if the cloud does not issue a command, the communication is ended.

When in first communication, the NB module is powered off and then electrified, the NB module is successfully attached to the base station and the login platform, and then data is sent, and if a command issued by the server is received, the command is analyzed; if no command is received and the idle time is up, setting the NB module to enter the PSM mode. When the PSM mode is failed, the power-off processing is carried out so as to keep the minimum function; if PSM is successfully entered, the NB module is not powered off and is in PSM mode. When the communication is carried out next time, if the communication needs to be electrified again under the condition of power failure, the base station is attached, and the platform flow is logged in; if in PSM mode, the login platform is operated by waking up the module.
