A low-cost IoT node wireless networking system and control method

Abstract

The invention discloses a low-cost Internet-of-things node wireless networking system and a control method. The system includes a cloud platform, a client, a smart node and a plurality of smart terminals. The smart node sends an inquiry packet to all the smart terminals, receives feedback packets returned by the smart terminals, filters or forwards the feedback packets to the cloud platform, and sends a control command issued by the client to the smart terminals. The cloud platform stores the ID information of all the smart terminals and corresponding verification service passwords. The client serves as a remote control end of the Internet-of-things node wireless networking system, and serves as a password input port for the verification code information of the smart control terminals. The fit between the smart node and the smart terminals is realized. Equipment can be installed or newly installed in a building without removing the installed equipment for upgrade.

Description

technical field [0001] The invention relates to an Internet of Things system for building electrical equipment, in particular to a low-cost wireless networking system and control method for Internet of Things nodes. Background technique [0002] Smart home and its products have broad market prospects and huge social and economic benefits, and have been widely welcomed in recent years. The wireless networking methods of smart home mainly include Wifi, Zigbee, etc. [0003] Invention Patent No. (2010101760174) proposes an electrical Internet of Things system, which realizes a new management and control method for equipment in smart buildings. The smart node of the Internet of Things is the core of smart home technology, and the wireless networking scheme uses the application-free section 433MHZ wireless communication technology, 433MHZ wireless communication technology has the advantages of low cost, low power consumption, strong penetrating ability, and high communication eff...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a low-cost Internet of Things node wireless networking system and control method, which realizes the information registration and authentication of the intelligent terminal module through the node broadcast command combined with the method of cloud platform authentication, in order to solve the problem of 433MHZ wireless communication in There is no anti-collision mechanism at the physical layer. When the intelligent terminal module feeds back information, a software delay algorithm is added to complete the conflict avoidance function. At the same time, in order to solve the problem that the obstacle between the intelligent terminal and the intelligent node cannot communicate, a dynamic routing relay is used. Method to complete the obstacle avoidance relay communication function
