Abstract

The present invention discloses a power line broadband carrier wave communication module. The module comprises a carrier wave control circuit (10), a carrier wave simulation front-end circuit (11), a carrier wave receiving circuit (12), a carrier sending circuit (13), a carrier wave signal coupling circuit (14), an electric power line interface (15) and a serial communication interface (16). The power line broadband carrier wave communication module separates the carrier wave simulation front-end circuit from the carrier wave control circuit to easily realize single-point grounding and avoid the mutual interference of the signals to the greatest extent, and therefore, the work efficiency is high (the anti-interference capability is high), the bandwidth is large (the transmission distance is long), the power consumption is low, and the parallel meter reading is realized so as to greatly improve the meter reading efficiency.

Description

technical field [0001] The invention relates to the technical field of power line carrier communication, in particular to a power line broadband carrier communication module. Background technique [0002] Power line carrier communication is a power system communication based on the transmission line as the carrier signal transmission medium. According to the available communication bandwidth, power line carrier communication is divided into narrowband carrier communication and broadband carrier communication, and has been widely used in the field of carrier meter reading. [0003] Narrowband carrier communication belongs to single carrier technology, and single carrier narrowband modulation technology mainly includes FSK, BPSK, frequency hopping, direct sequence spread spectrum, etc. The biggest defect of the single-carrier narrowband modulation technology is that it does not have the ability to adapt to time-varying frequency selective fading and interference, so it present...
