Graphic and storage method for condition data printing output of power protection apparatus

Abstract

The invention relates to a graphic and storage method for condition data printing output of a power protection apparatus, and belongs to the technical field of power data digital processing. The method is implemented by the following steps that 1) an instruction acquisition module is connected with a printing interface of the power protection apparatus and monitors the printing interface of the power protection apparatus in real time; 2) the instruction acquisition module analyzes received printing data and performs calculation to obtain corresponding printing instructions; 3) an instruction processing module converts the printing instructions into points on a local bitmap, so that an image consistent with printing contents is formed; and 4) when the printing instructions are printing end instructions, the bitmap is stored in a non-volatile storage medium. According to the method, all the printing instructions are converted into dot matrix images in a unified way and stored in a general format, namely, a bmp format of a local end, so that the compatibility and availability of information are improved.

Description

technical field [0001] The invention relates to a power protection device, in particular to a graphing and storage method for the printout of the situation data of the power protection device. Background technique [0002] The substation protection device monitors the operation of the power system, and prints the on-site situation data through the printer connected to the protection device as the main basis for fault analysis. Due to the complex structure of the power system, power system equipment, power system scheduling, and various disturbances and interferences may become factors for system abnormalities, and technicians need to make system diagnosis through paper original records. This method is time-consuming and laborious, and the efficiency is low. [0003] At present, the frequency of use of the printer used in the protection device is often not very high, and it may be in a standby state for a long time, resulting in the aging of the printer ribbon, dust pollutio...

Problems solved by technology

This method is time-consuming, laborious and inefficient

[0003] At present, the frequency of use of the printer used in the protection device is often not very high, and it may be in a standby state for a long time, resulting in the aging of the printer ribbon, dust pollution, paper jams and lack of paper, etc., and the printer needs to be maintained regularly. For the power system is a very large expense

At the same time, the stability and reliability of the printer itself is not very high, and the probability of equipment failure is high, resulting in the loss of on-site data and affecting the normal work of failure analysts.

[0004] On the other hand, paper materials are not conducive to the transmission and storage of on-site data, and are not conducive to the automation and intelligence of software-based analysis tools, causing unnecessary obstacles to data post-processing
