Problems solved by technology

[0003] However, a large number of NB-IoT water meter deployment applications, as well as the access of other NB-IoT IoT devices, NB-IoT network congestion is becoming more and more serious, even if the network access time of each device is discretized according to the uniqueness of the address. Congestion, but the NB-IoT devices of the same product category from different manufacturers or the reporting discrete mechanism of NB-IoT devices of different types cannot be effectively coordinated and coordinated, and the actual application scenario still cannot fundamentally solve the problem of network congestion

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] combined with figure 1 , a water meter data collection method based on Bluetooth networking, implemented based on a water master station, an Internet of Things platform, a Bluetooth NB-IoT water meter proxy node, and a Bluetooth water meter end node, specifically includes the following steps:

[0023] Step 1: When the data reporting time of the Bluetooth NB-IoT water meter is reached, the Bluetooth NB-IoT water meter proxy node changes from the Bluetooth slave mode (peripheral) to the host scan mode (scanner), and the Bluetooth water meter end node is in the slave mode. Bluetooth broadcast transmission Status, send Bluetooth device broadcast signal (broadcaster);

[0024] Step 2: The Bluetooth NB-IoT water meter proxy node starts to scan the broadcast sign...

Abstract

The invention discloses a water meter data acquisition method based on Bluetooth networking, which utilizes the characteristic of centralized installation of water meter wells, a Bluetooth NB-IoT water meter proxy node acquires data of other Bluetooth water meter tail end nodes installed nearby through networking Bluetooth, and integrally packs and uploads the data, so that the deployment number of NB-IoT water meter nodes can be greatly reduced, the problem of NB-IoT network data reporting congestion is solved, and meanwhile, due to the fact that only one Bluetooth NB-IoT water meter proxy node needs to be equipped with the NB-IoT module at one centralized installation point, the installation and maintenance cost of the overall solution can be remarkably reduced.

Description

technical field [0001] The invention relates to the field of Internet of things water meters, in particular to a water meter data collection method based on bluetooth networking. Background technique [0002] In the construction of urban water supply, serious leakage and low success rate of manual meter reading are faced. With the emergence and application of NB-IoT narrowband Internet of Things technology, this situation has been fundamentally changed. NB-IoTu has the characteristics of high security, wide coverage, large connection, low power consumption and low cost. It can effectively reduce the cost of meter reading and improve the accuracy of meter reading. It not only reduces the cost of manpower and material resources for the water sector, but also improves efficiency and Manageability also improves user experience. [0003] However, a large number of NB-IoT water meter deployment applications, as well as the access of other NB-IoT IoT devices, NB-IoT network conges...
