• 產品特點
• 周期上報:默認24小時上傳一次數據，時間上離散，保證項目區(qū)域內的遠傳水表都能正常上傳數據;
• 上傳數據內容:數據包含NB信號數據、周期采樣數據、上傳當前采樣數據、告警數據、電池電壓以及NB模組信息;
• 藍牙上報:增加藍牙通道，使水表上傳當前數據;
• 數據存儲:斷電情況下，表內數據須至少保存十年;能夠保證再次通電后數據自動恢復;報警功能:當遠傳水表出現電池電壓低、存儲故障、采樣;
• 出現故障、閥門故障等問題時上報異常數據至后臺系統(tǒng);
• 閥門控制:可遠程或者手持設備控制水表閥門的開和關。

Product features
Periodic reporting: By default, data is uploaded every 24 hours, with discrete time intervals to ensure that all remote water meters within the project area can upload data normally;
Upload data content: The data includes NB signal data, periodic sampling data, uploaded current sampling data, alarm data, battery voltage, and NB module information;
Bluetooth reporting: Add Bluetooth channel to enable the water meter to upload current data;
Data storage: In case of power outage, the data in the table must be stored for at least ten years; Can ensure automatic data recovery after power on again; Alarm function: When the remote water meter experiences low battery voltage, storage failure, or sampling;
Report abnormal data to the backend system when problems such as malfunctions or valve malfunctions occur;
Valve control: The opening and closing of water meter valves can be controlled remotely or by handheld devices.
