Problems solved by technology

[0010] To sum up, there are still electromechanical inconsistencies in the existing technology; the single meter needs to be powered by cables to the router and transmit signals, and the wiring makes implementation and maintenance difficult; the barcodes of the meter and the router need to be entered, and the meter and Corresponding to the router port, manual operation has high error rate, heavy workload, and low engineering efficiency; application scenarios are limited: wired matrix tables are suitable for centralized application scenarios such as pipeline wells, and cannot be used for decentralized applications such as household meters. Type of application scenarios; unable to intelligently deal with the problem of water waste caused by users forgetting to turn off the tap or other special circumstances

Embodiment 1

[0058] The present invention relates to a matrix wireless NB-IoT Internet of Things intelligent water meter system, including: a wireless intelligent water meter terminal, a matrix Internet of Things router, an operator cloud and a water service company cloud, a plurality of wireless intelligent water meter terminals and a matrix type The IoT router establishes communication, and multiple matrix IoT routers transmit data to the water company cloud through the operator's cloud, and the operator uses a PDA to obtain authority from the water company cloud to control the matrix IoT router.

[0059] The wireless smart water meter terminal includes: a water meter controller, a water meter radio transceiver module, a water meter clock chip, an acquisition unit, a water meter display, and a water meter power supply module, the water meter controller, a water meter radio transceiver module, a water meter clock chip, an acquisition unit, and a water meter Both the display and the water m...

Embodiment 2

[0068] The invention relates to a communication method for a matrix wireless NB-IoT Internet of Things smart water meter system, comprising the following steps:

[0069] S1: The matrix IoT router sends the connection signal, and the matrix IoT router sends the connection signal through the router radio transceiver module;

[0070] S2: The wireless smart water meter finally selects the connection signal with the highest link quality value for connection. The wireless smart water meter terminal scans the connection signals within the channel range through the water meter radio transceiver module, and judges the link quality value in the received connection signal. Select the connection signal with the highest link quality value to connect with the corresponding matrix IoT router;

[0071] S3: After receiving the connection request, the matrix IoT router searches the router memory for the existence of the MAC address of the wireless smart water meter terminal, and assigns the add...

example 1

[0084] When the signal strength is different and the connection number of the matrix IoT router is not full, the wireless smart water meter terminal will always connect to the matrix IoT router with the best signal. For example, A matrix IoT router is 10 meters to the left of B matrix IoT router, a and b wireless smart water meter terminals are placed 10 meters to the left of A matrix IoT router, and both a and b wireless smart water meter terminals use matrix A Internet of Things routers send tasks;

Description

technical field [0001] The invention relates to the technical field of intelligent water meter communication, in particular to a communication method for a matrix wireless NB-IoT Internet of Things intelligent water meter system. Background technique [0002] With the development of society, the demand for tap water is increasing year by year, people's awareness of environmental protection is increasing, and water resources are increasingly scarce. In response to the unified deployment of energy price programs by the National Development and Reform Commission, saving and effectively using water resources has become more and more popular in the international community. In addition, fresh water resources are directly related to economic benefits, so effective monitoring and management of tap water resources is very important and urgently needed. At present, most of the water meters on the market use traditional water meters that manually transcribe and manually count the water...
