Embodiment 1
[0041] Embodiment 1 of the present application provides an electric heating control system based on power line carrier communication, including a quantifier and multiple temperature controllers connected in parallel on the power line, and is suitable for electric heating control systems of single-phase power line and multi-phase power line carrier , each thermostat is used to control the start and stop of the heating equipment connected to it, the quantifier communicates with the thermostat through the power line carrier, and calculates the most suitable target thermostat for starting and stopping through the adjustment algorithm, so that the corresponding heating Equipment starts and stops heating to achieve optimal energy allocation.
[0042] image 3is a single-phase power line carrier control diagram, such as image 3 As shown, the power line is a 220V AC bus, and the quantifier and multiple thermostats are connected in parallel on the power line. The quantifier controls ...
Embodiment 2
[0071] Embodiment 2 of the present application provides a working method of an electric heating control system based on power line carrier communication, which is applied to a system composed of a quantifier and a thermostat;
[0072] Described quantifier working method comprises:
[0073] After the quantifier is powered on, the start signal is coupled to the power line through the power line carrier module and sent to the corresponding thermostat group;
[0074] And, the quantifier collects the total current of all thermostats from the power line. If the total current of the thermostat exceeds the preset total current set in the quantifier, it will query the most suitable thermostat group to stop. According to the most suitable The stopped thermostat group gets a stop instruction, and the stop instruction is coupled to the power line through the power line carrier module;
[0075] And, the quantifier receives the adjusted power consumption instruction sent by the upper appli...
