Smart home system based on carrier waves between ground wire and zero line

Abstract

The invention discloses a smart home system based on carrier waves between a ground wire and a zero line. The smart home system is characterized in that a remote control type electrical appliance, a branch controller module, a self-defined switch, a three-hole socket and a home internet of things gateway are all connected to a live wire, the zero line and the ground wire, and the home internet ofthings gateway is linked with a wireless sensor, a microcomputer, a smart phone and a generalized data interface; the remote control type electrical appliance and a fixed remote controller are connected with each other, the mobile self-defined switch and the branch controller module are connected with each other, and the three-hole socket is also connected with the branch controller module. The smart home system has the advantages of being great in data transmission function, excellent in signal isolation capability, high in signal transmission stability and data safety, low in system construction cost, capable of facilitating expansion in the later period and low in running load for a whole network. The system is beneficial to establishment of various technical standards of a smart home,greatly reduces the network load brought by a current smart home mode and saves public network resources.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to a smart home system based on a carrier between ground and neutral wires. Background technique [0002] The definition of smart home is to use integrated wiring technology, network communication technology, security technology, automatic control technology, audio and video technology to integrate home life-related facilities, build an efficient management system for residential facilities and family schedules, and improve home security. , convenience, comfort, artistry, and to achieve an environmentally friendly and energy-saving living environment. Its development prospects are very broad. [0003] The basis of the smart home system is the indoor data transmission system. Various functional electrical equipment, controllers and system management terminals are connected to the data transmission system to form an Internet of Things system, and the driving (control) program is a...

AI Technical Summary

Problems solved by technology

[0007] 3. Stability of signal transmission: if the device is disconnected, the function will be lost;

[0009] 5. Low cost: The cost is too high, which is difficult for ordinary families to accept and affects the promotion of products;

[0018] 1. There is no local controller for WIFI products, and all control points or monitoring points (electrical appliances) are directly facing the Internet as an independent terminal (directly connected to its cloud server through the Internet), so when the home intelligent system tends to be extensive and popular At this time, the load (concurrency) of the cloud server will increase significantly, which is undoubtedly a severe challenge to the server performance;

[0019] 2. With the continuous increase of such WIFI products in the family, the problem of dropped calls occurs frequently, which affects the user experience;

[0020] 3. The ability of WIFI products to resist intrusion is very poor, resulting in frequent occurrence of indecent video incidents on the Internet;

For smart homes, the disadvantages of incorporating household appliance control signals into high-bandwidth data transmission systems are obvious
