Problems solved by technology

[0009] In the development process of the power broadband carrier communication chip used on each communication node in the above-mentioned power carrier communication network, if the protocol layer and application layer software can only be developed based on the real hardware platform, in addition to the high cost of purchasing physical equipment, different manufacturers The functions supported by the concentrator and the electric meter are not complete, and basically can only be operated manually, and the controllability is weak; this makes the software development not only have a long development cycle, but also difficult to debug, and it is impossible to conduct completeness tests for various abnormal situations and different application scenarios

Abstract

This patent discloses a method for simulating inter-node communication, setting a virtual concentrator that can simulate the function of the concentrator sending operation commands and receiving operation results; setting multiple messages that can simulate a certain communication node of the power carrier communication network Sending and receiving function, and controlled by the hardware simulator of the upper layer module; a plurality of virtual data collection terminals that can simulate the function of the data collection terminal to generate messages and the function of message sending and receiving; set one for configuring the hardware simulator , the control unit of the virtual concentrator and the virtual data collection terminal; the control unit configures the virtual concentrator, the hardware simulator and the virtual data collection terminal, so as to be connected to a simulated power carrier communication network; the virtual concentrator, the hardware The simulator and the virtual data acquisition terminal simulate the communication behavior in the power carrier communication network according to their respective predetermined scripts.

Description

technical field [0001] The invention relates to the technical field of communication network simulation, in particular to a method for simulating inter-node communication. Background technique [0002] Power line carrier communication (PLC) refers to the communication method using the power line as the transmission medium. It is mainly used in: remote automatic meter reading, automatic control of distribution network, interconnection within the home, intelligent community and last mile network access of multimedia communication, etc. In recent years, the development of broadband power line communication technology has improved the data transmission rate of power line communication, especially the development of orthogonal frequency division multiplexing technology has enabled the realization of high-speed PLC. [0003] The remote automatic meter reading system using power line broadband carrier communication technology is a fully automatic meter data acquisition communicatio...
