NB-IoT物聯(lián)網(wǎng)水表
- 產(chǎn)品特點(diǎn)
- 周期上報(bào):默認(rèn)24小時(shí)上傳一次數(shù)據(jù),時(shí)間上離散,保證項(xiàng)目區(qū)域內(nèi)的遠(yuǎn)傳水表都能正常上傳數(shù)據(jù);
- 上傳數(shù)據(jù)內(nèi)容:數(shù)據(jù)包含NB信號數(shù)據(jù)、周期采樣數(shù)據(jù)、上傳當(dāng)前采樣數(shù)據(jù)、告警數(shù)據(jù)、電池電壓以及NB模組信息;
- 藍(lán)牙上報(bào):增加藍(lán)牙通道,使水表上傳當(dāng)前數(shù)據(jù);
- 數(shù)據(jù)存儲:斷電情況下,表內(nèi)數(shù)據(jù)須至少保存十年;能夠保證再次通電后數(shù)據(jù)自動恢復(fù);報(bào)警功能:當(dāng)遠(yuǎn)傳水表出現(xiàn)電池電壓低、存儲故障、采樣;
- 出現(xiàn)故障、閥門故障等問題時(shí)上報(bào)異常數(shù)據(jù)至后臺系統(tǒng);
- 閥門控制:可遠(yuǎn)程或者手持設(shè)備控制水表閥門的開和關(guān)。
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.
