Abstract

The application discloses an electric heating control system and working method based on power line carrier communication. The electric heating control system includes a quantifier and a plurality of thermostats connected in parallel on the power line; on the single-phase power line, the quantifier controls the data of the thermostats connected in parallel on the single-phase power line through the power line carrier module; On the phase power line, the quantifier is connected to the connection line between each group of thermostats and each phase power line, and the quantifier controls the data of the thermostat groups connected in parallel on each phase power line through the power line carrier module; the data control includes coupling based on the power line The data query is the most suitable target thermostat for starting and stopping, and the heating demand for heating equipment connected to the corresponding thermostat is started and stopped. This application uses power line carrier communication in the electric heating control system, which overcomes the shortcomings of independent wiring for wired control and poor wireless control signals, greatly facilitates construction, avoids conflicts between wireless signals, and reduces radiation.

Description

technical field

[0001] The present application relates to the field of electric heating control, in particular to an electric heating control system and working method based on power line carrier communication. Background technique

[0002] figure 1 It is a schematic diagram of the separate wiring of the power line and the communication line. At present, the communication between the heating master control and the heating controller mostly adopts the control mode of independent wiring communication, such as RS485, CAN bus and other communication methods. The disadvantage of independent wiring is that communication cables need to be wired separately. For new residential areas and factory buildings, the amount of construction needs to be increased, and for existing residential areas and factory buildings, etc., rewiring is required. However, the data transmitted during actual communication is very small, and separate wiring is overkill and useless. The rate is not high. In a...
