Abstract

The invention discloses a PLC household electrical appliance communication terminal system and relates to the field of Internet of Things. In the system, the input end of an air switch module is connected with home-entry power lines and the output end of the air switch module outputs multiple paths of indoor power lines; the indoor power lines are connected with household electrical appliance devices and PLC interfaces; all the PLC interfaces are connected with a main control board, and a part of the PLC interfaces are also connected with PLC conversion modules; the PLC conversion modules are used for realizing conversion between carrier wave signals and digital signals; and the main control board is used for realizing communication among different PLC conversion modules and communication between a household network and an external network. The system provided by the invention has the following advantages: relay effects are realized in terms of the attenuation of the lines and air switches to the carrier wave signals; a data forwarding function among different household electrical appliance household electrical appliances on different power lines or the same power line is realized through the PLC conversion modules; and information interaction between the household network and the external network is realized through a network module.

Description

technical field

[0001] The invention relates to the technical field of the Internet of Things, in particular to a PLC home appliance communication terminal system. Background technique

[0002] PLC (Power Line Communication, power line carrier communication) communication has achieved great success in electric remote meter reading, but it has hardly been applied in PLC home appliances. The main reason is that PLC home appliances have their own characteristics, which lead to Use the narrowband PLC scheme used in remote meter reading. The characteristics of PLC home appliances include high transmission speed, high operation stability, moderate transmission distance, etc., and the above characteristics require that when the signal is transmitted, the indoor wiring distance should not be too far or there can be forwarding in the middle Equipment; due to the serious attenuation of the signal by some air switches, when the home appliances are on different phase lines of the air s...
