Embodiment 1

[0055] Embodiment 1: A method for networking and data forwarding based on low-power micro-power wireless, which includes low-power sleep wake-up, networking beacon frame forwarding, node information collection, network configuration management, and data forwarding based on sleep wake-up copying strategies.

[0056] In this embodiment, the data information of water, gas and heat meters are gathered to the central node through low-power sleep wake-up, networking beacon frame forwarding, node information collection, network configuration management, and data forwarding and reading based on sleep wake-up. , and then sent to the concentrator and the master station through the uplink protocol.

Embodiment 2

[0057] Embodiment 2: A low-power micro-power wireless networking and data forwarding method as described in Embodiment 1, the low-power sleep wake-up, networking beacon frame forwarding process is:

[0058] a. The central node sends a wake-up packet, and then sends a networking beacon frame, which contains information such as the number of relay node time slots, the number of child node time slots, and the number of working channels;

[0059]b. The relay node self-awakens and receives the wake-up packet within the self-wake-up dormancy interval, waits for N wake-up packet cycles and then receives the networking beacon frame, according to the number of relay node time slots or sub The modulus of the number of node time slots and its own short address can obtain the corresponding forwarding time slot, and obtain the working channel in the networking beacon frame, and perform frequency hopping reception on the working channel and maintenance channel. The maximum timeout time for f...

Embodiment 3

[0067] Embodiment 3: A low-power micro-power wireless networking and data forwarding method as described in Embodiment 2. During the low-power sleep and wake-up process, the central node selects a superframe structure, according to the number of relay nodes and child nodes , to draw a range for the time of the channel; the forwarding time slot interval and the number of time slots of the relay node and the sub-node are specified in the super frame; the super frame is bounded by the transmission of the networking beacon frame.

Abstract

The invention discloses a wireless networking and data forwarding method based on low power consumption and micro power. The method is characterized by comprising low power consumption dormancy awakening, forwarding beacon frame forwarding, node information acquisition, network configuration management and data forwarding and reading strategy based on dormancy awakening. The method has the advantages that 1) networking function: by combining good radio frequency performance, the wireless transmission distance can be greatly prolonged, and the problem of communication dead angles of a current wireless meter is solved; 2) good communication timeliness: a master station actively initiates communication, and a child node gives a response within a few seconds, so the user experience is good; and 3) the meter can run with ultra low power consumption through the awakening scheme described in the method, and the water meter supplied with power by a battery can be used for over 8 years in comprehensive consideration of field environment.

Description

technical field [0001] The invention belongs to the field of low-power and micro-power wireless ad hoc network communication, in particular to a low-power and micro-power wireless centralized copying method with a sleep mode. The invention is used to solve the problem of power consumption of battery-powered equipment and the problem of long-distance network communication of the equipment in the four-meter centralized reading system. Background technique [0002] In recent years, with the rapid development of technologies such as wireless communication, integrated circuits, and control systems, mass production and use of low-cost, low-power, and multi-functional wireless sensing devices has become possible. In the fields of four-meter collection, smart home, Internet of Things and other fields, the application prospect of low-power and micro-power wireless ad hoc network communication technology related to wireless sensing equipment is also broader. In the field of centraliz...
