Problems solved by technology
In this way, for solar water heaters with indoor controllers and auxiliary electric heating, two sets of transmission lines need to be laid, which not only requires high construction sites, but also troublesome construction and installation. If it is damaged, it is very easy to connect the strong current to the weak current line, burn out the weak current line and its related components, and affect the normal use of the water heater

The invention discloses a signal transmission method and a transmission device for a solar water heater. The solar water heater comprises an electric heating device, an indoor controller and an outdoor controller, wherein the indoor controller and the outdoor controller are connected by an electrical power cable; the electric power cable is used for time-sharing transmission of electric power supply and parameter signals; especially, under a power supply mode, the indoor controller provides power supply for the outdoor controller and the electric heating device through the electric power cable; and under a communication mode, the outdoor controller transmits parameter signals to the indoor controller through the electric power cable. The invention utilizes the electric power cable for thetime-sharing transmission of electric power supply and parameter signals of water temperature, water level and the like, can reduce lines required for installing the water heater, and simplifies the construction and installation process.
Description
technical field [0001] The invention relates to an information transmission method and device, in particular to a method and a device for transmitting signals by a solar water heater, belonging to the technical field of solar water heaters. Background technique [0002] Existing solar water heaters are generally equipped with indoor controllers, which can realize automatic water supply, and are used to display parameter information such as water level and water temperature in the water tank of the water heater, so that users can grasp the state of the water in the water tank at any time. In addition, in order to ensure that the temperature of the water in the solar water heater meets the demand even when the ambient temperature is low and the sunlight is insufficient, or to prevent the upper water pipe from freezing and cracking, an auxiliary electric heating device is provided for the water heater. [0003] The detection and transmission of water temperature, water level an...
