Problems solved by technology

Power line carrier communication is prone to communication errors caused by harmonic interference in the line. If the zero-crossing modulation method is used, although the anti-interference is better, the communication rate is low, so the application is very limited.

Embodiment Construction

[0021] The K-10 protocol of the present invention is actually a serial communication protocol specially developed for the control characteristics of the intelligent power distribution system to adapt to the accurate transmission of digital information in the industrial frequency AC power line. Its characteristics include steps:

[0022] (1) Digital information setting steps: use a series of pulse sequences to represent a complete digital information, the first half of the pulse sequence represents address information, including feature code, household number, room number, electrical appliance number, and the latter part of the pulse sequence The half part is the control code, which represents control and protocol information, including opening, closing, power adjustment, and running status. A K-10 message consisting of 34 pulses is obtained. The complete information of the K-10 message is:

[0023] Feature code + 4-digit household number + 4-digit room number + 4-digit electric...

Abstract

A carrier wave communication method realizing power line carrier wave communication is characterized in that the complete information of K-10 information is set as follows: a feature code + a 4-bit house number +a 4-bit room number + a 4-bit electric equipment code + a 3-bit control code; three '1' pulses followed with a '0' pulse form an identification code; the house number, the room number and the electric equipment code set the pulse through adopting 4-bit binary codes; and the control code sets the pulse through adopting a 3-bit binary code and deals with the pulse through methods of zero crossing emission and detection. The carrier wave communication method has the advantages of convenience, low price and reliability, and is particularly suitable for the use of the intelligent power distribution system.

Description

technical field [0001] The invention relates to the technical field of power line carrier communication, in particular to a carrier communication method for realizing power line carrier communication in an intelligent power distribution system. Background technique [0002] Using AC power lines to transmit data can realize data communication without laying special data communication lines, which can greatly simplify the hardware structure of the circuit system and reduce costs. It is an advanced and practical technology. Power line carrier communication is prone to communication errors due to harmonic interference in the line. If zero-crossing modulation is used, although the anti-interference is better, the communication rate is low, so the application is very limited. With the rise of smart homes, smart power distribution systems have a great demand for power line carrier communication technology, because smart power distribution systems need to be convenient, cheap, and r...
