Abstract

The invention provides an embedded relay protection device and a network printing method thereof, and belongs to the technical field of electric power data digital processing. The network printing method provided by the invention comprises the following steps: (1) analyzing printing data in an ESC/P printing data stream buffer area according to an ESC/P printing data coding format; Generating a BMP bitmap corresponding to the printing data by utilizing a BMP bitmap generation engine according to the typesetting format of the printing data; (2) generating script data corresponding to the BMP bitmap by utilizing a script conversion engine; And (3) sending the script data to a network printer for printing. The embedded relay protection device solves the problem that the existing embedded relay protection device cannot realize a network printing function due to the fact that a related driver of a network printer cannot be installed inside the existing embedded relay protection device.

Description

technical field [0001] The invention relates to an embedded relay protection device and a network printing method thereof, belonging to the technical field of electric power data digital processing. Background technique [0002] Relay protection equipment is the most important equipment in the secondary system of a substation. The printing function is one of its most basic functions, and it is also the main means for on-site operation and maintenance personnel to obtain equipment information. With the widespread application of digital IE 61850 technology in the power system, the trend of networking in the secondary system of substations is becoming more and more obvious. Sampling data, switch information and other key information are transmitted through optical fiber Ethernet, and the information interconnection of the entire substation becomes a reality. [0003] Relay protection devices usually use serial dot matrix printers to realize printing functions, such as Epson 30...
