Abstract

The invention provides a system and a method of power line carrier communication. The system for power line carrier communication comprises a sensor, a transmitting device, a receiving device and a microprocessor, wherein the sensor is connected onto the transmitting device for acquiring environmental information and generating sensing signals; the transmitting device is arranged at one end of the power line for loading the sensing signals to the power line in a condition of power transmission by the power line; the receiving device is arranged at the other end of the power line for detecting sensing signals on the power line; and the microprocessor is connected with the receiving device for analyzing and processing the sensing signals. Through the technical scheme of the invention, a signal line needed by sensor communication and the power line can be combined, the signal transmission efficiency can be improved through a carrier frequency adjustment mode, the number of serial communication lines is reduced and the communication speed is enhanced.

Description

Technical field [0001] The present invention relates to the technical field of power line carrier communication, in particular, to a power line carrier communication system and a power line carrier communication method. Background technique [0002] Common weak current communication includes parallel port communication and serial port communication. Parallel port communication generally uses 8 bits, 10 bits, 16 bits, etc. according to the system's data. Serial communication generally uses dedicated 3-wire, dedicated 2-wire, and dedicated 1-wire methods. Obviously, the more lines, the more space occupied, and the smaller the number of lines, the smaller the space occupied. Generally speaking, the transmission speed will be slower when the number of serial communication lines is less. However, in practical applications, it is hoped that the fewer lines the better, in order to keep the system simple. [0003] Therefore, how to reduce the number of serial communication lines while inc...
