The invention relates to the field of light string control, and especially relates to a voltage self-adaption method and system based on a power line carrier, equipment and a storage medium. The voltage self-adaption method based on the power line carrier comprises the following steps: acquiring data flow information, wherein the data flow information comprises data flow voltage; obtaining a reference voltage according to the data flow voltage; and decoding the data flow voltage according to the reference voltage. According to the data flow voltage self-adaption detection method, the reference voltage is directly acquired from the signal of the data flow without depending on the reference of the fixed data flow voltage, and the current data flow is decoded by the reference voltage of the current data flow, so that the defect of limitation on the absolute value of the data flow voltage is overcome, and the applicability of the power line carrier is improved.
Description
technical field [0001] The present application relates to the field of light string control, and in particular to a power carrier-based voltage adaptive method, system, device and storage medium. Background technique [0002] Power carrier is a unique communication method for power systems. Power carrier communication refers to the technology of using existing power lines to transmit analog or digital signals at high speed through carrier waves. It does not need to lay additional communication lines and directly utilizes existing power line resources. Data transmission, which will greatly reduce communication costs, has great advantages over other communication methods, and is widely used in cable anti-theft, various lighting control, and pan-tilt control of monitoring systems. [0003] Low-voltage power carrier communication uses the low-voltage power line as the communication carrier. The data is modulated to a carrier frequency of tens to hundreds of KHz by the sending en...
