Abstract

The invention relates to a wireless intelligent remote water meter based on NB-IOT. The water meter comprises a control circuit arranged in an upper cavity of the water meter body, and the control circuit comprises an MCU master control, a sensor module, a display module, an NB-IOT wireless transmission module, a warning module and a power supply module; the MCU master control module is used for converting collected signals into water flow information, the sensor module is used for collecting voltage and pulse signals, and the sensor module, the display module, the NB-IOT wireless transmissionmodule, the warning module and the power supply module are connected with the MCU master control module; the sensor module comprises a stepping motor sensor and one or more hall sensors; the output end of the NB-IOT wireless transmission module is connected with an NB-IOT antenna and connected with a cloud server through an NB-IOT cellular base station. According to the water meter, by arrangingthe NB-IOT wireless transmission module, the water meter works in an authorized frequency band so as to achieve wireless meter reading.

Description

technical field [0001] The invention relates to the technical field of water meters, in particular to a wireless intelligent remote transmission water meter based on NB-IOT. Background technique [0002] Most of the water meters on the market are mechanical water meters, which require manual meter reading, which is time-consuming and laborious; there are also some small wireless water meters in the unlicensed frequency band, which are easily interfered by external signals, with low meter reading efficiency and high error rate. The function is single, unable to keep pace with the times, and unable to adapt to the needs of intelligent society progress. Therefore, on the basis of the existing water meter structure, such as the water meter structure disclosed in the patent No. 201610214331.4, the water flow information is collected by using sensors, and the wireless meter reading function is added. [0003] In addition, the iron case of water meters cast by sand casting is curr...
