Line controller power carrier communication structure

Abstract

The invention discloses a line controller power carrier communication structure which comprises a main controller and a line controller as well as a power carrier line used for connecting the main controller with the line controller. The line controller power carrier communication structure is characterized in that a driving circuit butted with the line controller is arranged on the main controller and comprises a transmitted signal processing circuit and a received signal conversion circuit; a sampling circuit and a rectifying voltage-stabilizing circuit are arranged on the line controller; the sampling circuit is used for converting and then outputting a control signal transmitted by the main controller to a line controller chip and encoding a command of the line controller chip to an electric signal and then transmitting the electric signal to the main controller; the rectifying voltage-stabilizing circuit is used for powering up the line controller. According to the invention, serial communication (four-line) of an original line controller is broken through, and according to a power carrier principle, two non-polar connecting lines are used as both a data transmission channel and a power supply channel, so that the functions of water heater running and water heater running state displaying of the line controller are realized.

Description

technical field [0001] The invention relates to a wire controller for a gas water heater, in particular to a power carrier communication structure of the wire controller. Background technique [0002] At present, gas water heaters have been widely used in ordinary households. The bathroom is generally a closed space. For the safety of use, ordinary water heaters cannot be installed, but ordinary gas water heaters need to be installed in a well-ventilated place. Because most ordinary gas water heaters adjust the water temperature through the mixing valve, due to the instability of the water pressure, there will be occasional hot and cold conditions. If the water temperature cannot be adjusted in real time during use, it will greatly affect the comfort of bathing. [0003] In the prior art, in order to facilitate the user to realize real-time adjustment of the water temperature in the bathroom, a wire controller connected to the main controller of the gas water heater is usual...

AI Technical Summary

Problems solved by technology

In order to realize the amount of signal transmission and power supply between the wire controller and the main controller, two lines of power lines and signal lines need to be arranged between the wire controller and the main controller at present, the structure is complex and the wiring is inconvenient

With the development of circuit carrier technology, although some people put forward the idea of ​​using the power carrier line to realize the signal and power transmission between the wire controller and the main controller at the same time, but because the control signal is greatly affected by the power signal and the distortion is more significant, Has not been promoted and applied in existing products
