NB IoT water meter

NB-IoTThe IoT water meter adopts high-performance and low-powerNB-IoTTechnology, using authorized narrowband4GNetwork transmission, with deep signal network coverage (underground surface wells, pipeline wells, etc. can all be used normally), ultra-low power consumption, stable and reliable communication. Easy to install and use, no need for a collector, no need for separate debugging, and can be used by connecting to a computer through the upper computer after installation.

Functional Features

Can be done throughNB-IoTTechnology is used for data transmission, and when there is no data communication, it automatically enters a low-power state to reduce power consumption. Internally containing8year4GFree data usage. At present, it supports two modes: fixed-point upload and periodic upload. Upstream and downstream useUDPProtocol eliminates unnecessary signaling and is more suitable for low power consumption,IPThe address and port number can be modified as needed.

Performing anti shake processing during the detection of pulse signals can effectively avoid erroneous measurements caused by external interference and improve measurement accuracyAt the same time, the water meter also has a pulse signal anomaly detection function, which can detect pulse signal faults and strong magnetic interference, and record abnormal states.

Regularly check the battery voltage, record the undervoltage status and report abnormal voltage status when the battery experiences undervoltage, save measurement data, and prevent data loss.

When two pairs of pulse signal ports simultaneously detect that both sensors of the water meter have been attracted and exceeded15In seconds,NBThe water meter module will detect the occurrence of magnetic interference and record this abnormal state. During meter reading, these abnormal state data will be reported to the server. Modules with valve control function, in the presence of continuous magnetic interference phenomenon10The valve will automatically close in seconds, and the interference phenomenon will disappear10Restore the valve status in seconds to prevent users from stealing water.
