NB-IOT water meter with high communication efficiency

Abstract

The NB-IOT water meter comprises a plurality of NB-IOT water meters based on the same limited area, each NB-IOT water meter comprises a wireless transmission receiving and dispatching module and a filtering module and further comprises at least a plurality of sub-transmission receiving and dispatching modules, each sub-transmission receiving and dispatching module comprises a plurality of sub-transmission receiving and dispatching modules, and each sub-transmission receiving and dispatching module comprises a wireless transmission receiving and dispatching module and a filtering module. The NB-IOT water meter has the advantages that the NB-IOT water meter is provided with a plurality of sub-transmission transceiver modules, each sub-transmission transceiver module and the wireless transmission transceiver module of the single NB-IOT water meter belong to the same frequency band and form wireless connection, the NB-IOT water meter with high-efficiency communication adopts a multi-stage communication and multi-stage filtering structure, and meanwhile, one branch and one frequency band are adopted, so that the purpose of high-efficiency communication is achieved.

Description

technical field [0001] The invention relates to the technical field of NB-IOT water meters, in particular to an NB-IOT water meter with high-efficiency communication. Background technique [0002] The so-called NB-IOT water meter, that is, NB-IOT wireless Internet of Things remote transmission water meter, NB-IOT is the narrowband Internet of Things, and the narrowband Internet of Things is gradually becoming an important branch of the Internet of Everything. NB-IoT is built on a cellular network and only consumes about 180kHz of bandwidth. It can be directly deployed on a GSM network, UMTS network or LTE network to reduce deployment costs and achieve smooth upgrades. NB-IOT wireless Internet of Things remote water meter is based on pulse remote water meter, photoelectric direct reading remote water meter, camera remote water meter, mechanical sensor remote water meter, etc., with integrated NB-IOT communication module, single meter A remote smart water meter for remote tra...

AI Technical Summary

Problems solved by technology

NB-IOT wireless Internet of Things remote water meter is based on pulse remote water meter, photoelectric direct reading remote water meter, camera remote water meter, mechanical sensor remote water meter, etc., with integrated NB-IOT communication module, single meter A remote smart water meter for remote transmission, that is to say, the water meter mainly relies on the NB-IOT communication module based on the narrowband Internet of Things to achieve the purpose of wireless communication and automatic meter reading. However, due to factors such as signal interference and different regions, The strength of the electromagnetic wave signal is different, resulting in the NB-IOT water meter relying solely on the NB-IOT communication module. In many cases, it will still be interfered by many wireless transmissions, which directly affects the communication.
