Electric heating control system based on power line carrier communication and working method

Abstract

The invention discloses an electric heating control system based on power line carrier communication and a working method. The electric heating control system comprises a meter and a plurality of temperature controllers connected in parallel on a power line. On a single-phase power line, the meter performs data management and control on the temperature controllers connected in parallel on the single-phase power line through a power line carrier module. On a multi-phase power line, the meter is connected to a connecting line of each temperature controller and each phase of the power line, and the meter performs data management and control on the temperature controllers connected in parallel on each phase of the power line through the power line carrier module. Data management and control comprise measures of inquiring the target temperature controller which is most suitable for starting and stopping according to the data coupled on the power line and starting or stopping heating of heating equipment connected to the corresponding temperature controller. Power line carrier communication is used in the electric heating control system, so that the defects that wired control needs independent wiring and wireless control is poor in signal are overcome, construction is greatly facilitated, conflicts of wireless signals is avoided, and radiation is reduced.

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...

AI Technical Summary

Problems solved by technology

However, wireless communication is greatly affected by buildings. For heating controllers that are far away from the main heating control, there will be wireless communication control dead angles. If the transmission power is increased, it will solve certain problems, but it will increase the cost and increase the radiation.

Similarly, for heating systems with small transmission data, using wireless control is also overkill, and the actual utilization rate is very low
