NB-IoT Water Pressure Sensors in Pump House Application Case

Application Background

Water pump room is placed in the living water pump equipment room, through the pumping way for life, production to provide the required water pressure. And also can provide high pressure water source for fire fighting, when the building fire, the use of water pumps to start pumping up the water reservoir to meet the water pressure and amount of water needed to fight the fire. In addition, the pump room can also transport oil, acid and alkali liquids and other liquids.

 

The water pump room monitoring system is based on wireless communication technology, Internet of Things and its hardware equipment as the main constituent equipment, which guarantees the intelligent management of the pump room, improves the service life of the pump, avoids the risk of water pollution, reduces the leakage rate, is environmentally friendly and energy-saving, improves the fine management level of the water supply pump room, creates the modernized pump room with fewer people or no one to be on duty, and guarantees normal and stable water supply and at the same time, guarantees the fire safety.

 

prescription

The water pressure transmitter uses a diffusion silicon piezoresistive pressure sensor with stainless steel isolation membrane as the signal measuring unit, and the signal processing and transmission unit is located in the circular housing.
The sensor signals are acquired with high precision data acquisition, while the temperature and static pressure are compensated with digital compensation technology to improve the measurement accuracy and reduce the temperature drift; after the data processing, the pressure values are transmitted via wireless NB-IoT.

 

System framework

NB-IoT (Classification of IoT interface types)

NB-IoT Narrow Band Internet of Things (NB-IoT) has become an important branch of the Internet of Everything.NB-IoT has a special focus on indoor coverage, low cost, long battery life, and high connectivity density.NB-IoT uses a subset of the LTE standard, but limits the bandwidth to a single narrow band at 200kHz. It uses OFDM modulation for downlink communications and SC-FDMA for uplink communications.NB-IoT is built on cellular networks, consumes only about 180kHz of bandwidth, and can be deployed directly on GSM networks, UMTS networks, or LTE networks; NB-IoT focuses on the low-power, wide-range (LPWA) Internet of Things (IoT) market, and is an emerging technology that can be used globally on a NB-IoT focuses on the low-power wide coverage (LPWA) IoT market, and is an emerging technology that can be widely applied worldwide. It is characterized by wide coverage, multiple connections, fast rate, low cost, low power consumption, and excellent architecture. Due to these features, applications are in the areas of parking, meter reading, firefighting, water hydrology, street lighting, bike sharing, and home appliances
