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

Abstract

The invention discloses an electric heating control method and system based on power line carrier communication. The method comprises the following steps that a temperature measuring device is paired with a controller, and after successful pairing, the temperature measuring device is installed in a heating space controlled by the corresponding controller for temperature measurement; the temperature measuring device collects heating space data in real time and transmits the collected real-time data to a tuner through a power line carrier module; the real-time data collected by the tuner are subjected to real-time data analysis, a control module is started / stopped according to the analysis result, and starting / stopping of the control module decides power supply to / cut off from the load. According to the method and the system, the load and temperature measurement are separated, the influence on temperature measurement caused by the heating reason of the temperature measuring device is reduced, the temperature measurement precision is improved, the installation difficulty is reduced, fool-type installation is realized, the technical requirements on construction workers are reduced, and the temperature measurement position is more flexible; in addition, due to strong current control, noise pollution caused by a common temperature controller relay is reduced at the electric box end, and meanwhile, the service life is prolonged.

Description

technical field [0001] The present application relates to the field of electric heating control, in particular to an electric heating control method and system based on power line carrier communication. Background technique [0002] The existing electric heating method generally realizes the communication between the heating equipment by separately arranging communication lines, such as RS485 bus, etc. At this time, it is necessary to separately wire the communication cables. Residential areas, factories, etc. need to be re-wired, but the data transmitted during actual communication is very small, and the single wiring is overkill and the utilization rate is not high. [0003] In addition, some existing heating equipment needs to be controlled by relays, and the noise emitted by the relays in the bedroom is particularly obvious in the dead of night, which seriously affects the user experience. Therefore, there is an urgent need for an electric heating control that can reduce...

Problems solved by technology

[0002]The existing electric heating method generally realizes the communication between the heating equipment by arranging communication lines separately, such as RS485 bus, etc. At this time, it is necessary to wire the communication cables separately , For newly-built communities, factories, etc., it is necessary to increase the amount of construction, and for existing communities, factories, etc., it is necessary to re-wire. However, the data transmitted during actual communication is very small, and the single wiring is overkill and the utilization rate is not high.

[0003] In addition, some existing heating equipment needs to be controlled by relays, and the noise emitted by the relays in the bedroom is particularly obvious in the dead of night, which seriously affects the user experience, so There is an urgent need for an electric heating control method and system that can reduce both cost and noise
