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...
