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

The invention discloses a method for simulating communication between nodes. A virtual concentrator which can simulate the function of a concentrator to send operation commands and collect operation results is provided. A hardware simulator for simulating a communication node of a power carrier communication network is provided, and is controlled by an upper module of the hardware simulator. A plurality of virtual data acquisition terminals capable of simulating the functions of the data acquisition terminals to generate messages and the functions of sending and receiving messages are set. A control unit for configuring the hardware simulator, the virtual concentrator and the virtual data acquisition terminal is set. The control unit configures the virtual concentrator, the hardware simulator and the virtual data acquisition terminal so as to be connected into an analog power carrier communication network. The virtual concentrator, the hardware simulator and the virtual data acquisition terminal are made to simulate the communication behavior in the power carrier communication network according to their respective 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...
