NB-IoT物联网水表
- 产品特点
- 周期上报:默认24小时上传一次数据,时间上离散,保证项目区域内的远传水表都能正常上传数据;
- 上传数据内容:数据包含NB信号数据、周期采样数据、上传当前采样数据、告警数据、电池电压以及NB模组信息;
- 蓝牙上报:增加蓝牙通道,使水表上传当前数据;
- 数据存储:断电情况下,表内数据须至少保存十年;能够保证再次通电后数据自动恢复;报警功能:当远传水表出现电池电压低、存储故障、采样;
- 出现故障、阀门故障等问题时上报异常数据至后台系统;
- 阀门控制:可远程或者手持设备控制水表阀门的开和关。
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.
