Method for realizing image data transmission based on power line high-speed carrier HPLC

Abstract

The invention discloses a method for realizing image data transmission based on power line high-speed carrier HPLC. The method comprises the following steps: firstly, an image acquisition module uploads an event notification to a corresponding concentrator after detecting an abnormal signal; then, the concentrator starts to read the image file and sends a file request signal to the active sensingmodule; then, the image acquisition module sends an acquired image data packet to the active sensing module according to a request command of the concentrator, then, the concentrator receives the image data packet, caches the image data and returns to continue requesting a subsequent image file until the image file is received completely, and finally, the concentrator starts and reports the imagefile to the main station. According to the invention, an electricity inspector can remotely check the operation condition of the website meter box, the advantages of large HPLC communication bandwidthrange, weak noise and the like are utilized, the range suitable for the terminal module is expanded, and the accuracy of image data transmission is ensured.

Description

technical field [0001] The invention relates to the technical field, in particular to a method for realizing image data transmission based on power line high-speed carrier HPLC. Background technique [0002] The low-voltage distribution network is located at the end of the entire power grid. It has the characteristics of wide distribution, complex power supply environment, and difficult operation and maintenance. It has long lacked intelligent and efficient operation monitoring and operation and maintenance management methods. There are the following two problems: (1) large personnel input and long investigation time period; (2) the lock of the metering box is seriously damaged by external forces, and there is no meter electricity, and there is a phenomenon of stealing electricity outside the meter, which cannot be found through artificial system analysis Or it is not timely to discover the stealing behavior, which will cause great economic losses to the enterprise.

[0004] Power line communication can be divided into narrow-band low-speed power line communication, narrow-band high-speed power line communication and broadband high-speed power line communication according to the working frequency band. The frequency that narrow-band power line communication can use is relatively narrow because of its relatively narrow bandwidth. The success rate of the table is difficult to break through more than 90%
