Problems solved by technology

Bluetooth technology is a radio technology that supports short-distance communication (generally within 10m) of devices. It works in the globally common 2.4GHz ISM (industrial, scientific, and medical) frequency band, adopts fast frequency hopping and short packet technology, and supports point-to-point and point-to-point Multi-point communication, using time division duplex transmission scheme to achieve full-duplex transmission; Zigbee's proposal can be used for flexible networking, but the increase in equipment complexity and cost caused by networking cannot be ignored, and it is still necessary Active power supply; at the same time, as the utilization rate of 2.4GHz ISM increases, the use of frequency bands becomes more and more intensive, and the problems of radio frequency interference and frequency reuse between various wireless LANs become more and more serious

Embodiment 1

[0034] Such as Figure 1-2 As shown, a method for networking of low-power passive wireless nodes based on RSSI comprises the following steps:

[0035] S1: Build a background management center, control nodes, and several passive wireless nodes to form a wireless network. Among them, the background management center is used to process and store data,

[0036] The control node controls the passive wireless nodes, including performing networking and adding, deleting, checking, and modifying the passive wireless nodes in the wireless network,

[0037] The passive wireless node collects the data and sends it to the control node;

[0038] S2: The passive wireless node adopts the self-harvesting power supply method of collecting and converting tiny energy into electric energy and stores the energy, and completes data collection and data transmission to the control node;

[0039] S3: The control node adopts the active power supply mode, interconnects scattered passive wireless nodes,...

Abstract

The invention provides an RSSI-based low-power consumption passive wireless node networking method. According to the invention, networking is carried out by use of self-capacitation passive wireless nodes, and an optimal transmission router and an Internet with smallest communication consumption are established, so stability and uniformity of the network are ensured and an effect of low-power consumption high-quality wireless communication of a wireless network is achieved on a bidirectional communication function.

Description

technical field [0001] The present invention relates to the field of wireless communication, more specifically, to a method for networking of passive wireless nodes with low power consumption based on RSSI (Received Signal Strength). Background technique [0002] At present, there are many companies and manufacturers researching smart homes, but the products developed by these companies and manufacturers need to be wired inside the wall, and the installation needs to cause great changes to the appearance of the existing living room. It is difficult to maintain and it costs a lot of money. It is also very high, the system installation is troublesome, and the interface is too complicated; at the same time, these products also need active power supply, whether it is the use of power on resources or battery power, considering the use of resources and the pollution-free treatment of battery recycling Difficulty is contrary to the proposed green and intelligent buildings. [0003...
