Abstract

A power line carrier communication system based on a general MCU comprises a core device, a data sending assembly and a data receiving assembly, and the data sending assembly is used for converting binary data to be sent into FSK data; the data receiving component is used for converting the received FSK data into binary data; the core device comprises a programmable logic block module and a state machine timer module, and the programmable logic block module is used for storing preset logic; the state machine timer module is used for converting the binary data into the FSK data or converting the FSK data into the binary data according to the preset logic in the editable logic block module; the system can achieve automatic conversion of the FSK signals and the binary signals in the data sending and receiving process, the whole process does not need CPU participation, the data receiving and sending efficiency is high, and the load of the CPU is effectively reduced, so that a user can preferentially utilize the CPU to complete the core task under the condition of limited resources, and the efficiency of processing the core task by the CPU is improved.

Description

technical field [0001] The invention relates to the field of communication system design, in particular to a general-purpose MCU-based power carrier communication system. Background technique [0002] Computer communication is transmitted on data lines (telephone lines, network cables, optical fibers or wireless media), using FSK modulation signals, that is, converting binary data into FSK signal transmissions, and in turn demodulating the received FSK signals Convert it into binary data and convert it into a binary language represented by high and low levels, which is a language that computers can directly recognize. The process of data receiving and sending generally requires the participation of the CPU, not only the signal transmission efficiency is not high, It also takes up CPU resources, causing the CPU to be unable to process core tasks in a timely manner. [0003] Therefore, how to improve the efficiency of signal transmission in the power carrier communication sys...
