Remote monitoring system based on matrix NB-IoT intelligent water meter

Abstract

The invention relates to a remote monitoring system based on matrix NB-IoT intelligent water meter. The system comprises matrix NB-IoT intelligent water meters, a NB-IoT Internet of things and a cloudplatform. Each of the matrix NB-IoT intelligent water meters comprises a controller, a plurality of base meters and flow sensors installed on the base meters, and a flow sensor on each base meter isconnected to the controller. The matrix NB-IoT intelligent water meters are connected to the cloud platform through the NB-IoT Internet of things to realize a remote monitoring function. According tothe invention, a main control module can mount the matrix NB-IoT intelligent water meters with the multiple base meters to perform data transmission with the cloud platform, the electromechanical conversion and data collection and recording are performed through the main control module and the multiple base meters, the data exchange with the cloud platform is carried out, the material cost can begreatly reduced without reducing the performance of the water meters, and the cost of reconstructing a NB-IoT remote intelligent water meter can be greatly reduced due to low cost.

Description

technical field [0001] The invention belongs to the technical field of smart water meters, in particular to a remote monitoring system based on a matrix NB-IoT smart water meter. Background technique [0002] With the promotion and application of NB-IoT communication technology, a remote monitoring system for smart water meters based on NB-IoT communication technology came into being. The NB-IoT smart water meters in the above-mentioned remote monitoring system are all NB-IoT remote intelligent stand-alone water meters, which are usually composed of an intelligent control module connected with a base meter. It has the following advantages: (1) NB-IoT remote intelligent stand-alone water meter adopts NB-IoT communication technology to achieve low power consumption, strong link, high coverage, high-precision wireless data transmission function, and has lower power consumption than GPRS water meter , long service life; (2) The intelligent control module is responsible for the ...

AI Technical Summary

Problems solved by technology

[0003] Although NB-IoT remote intelligent independent water meters have the above advantages, the existing NB-IoT intelligent water meters generally have the following problems: (1) Since NB-IoT remote intelligent independent water meters need to be equipped with intelligent control modules and Base meter, so the cost of water meter is high; (2) Since each meter of NB-IoT remote intelligent independent water meter needs NB-IoT communication fee, the communication fee is high; (3) NB-IoT remote intelligent independent water meter The service life of lithium batteries is generally between 6 and 8 years, and the service life of lithium batteries is relatively short; (4) Since NB-IoT remote intelligent independent water meters are composed of an intelligent control module and a base meter, the failure If the quantity is high and the intelligent control module is sealed in the housing of the base meter, once the intelligent control module fails or the base meter fails, it needs to be replaced together, which results in high maintenance costs

[0004] To sum up, the existing NB-IoT smart water meters have problems such as equipment cost, operating cost, maintenance cost and battery life, and the remote monitoring system based on the above-mentioned NB-IoT smart water meters is difficult to be widely promoted and applied.
