Problems solved by technology

At present, the data printed by the relay protection equipment of the power system are all stored in paper form. The disadvantages are: 1. The print data can only be stored in the local relay protection equipment, and the printing efficiency of paper is low and the cost is high; 2. Proofreading and editing of print data can only be done on the local relay protection device, but cannot be done on other devices

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] like figure 1 As shown, in the embodiment of the present invention, a power system relay protection equipment print transmission data acquisition device is proposed, which cooperates with the management equipment. The device is set on the data line connected between the relay protection equipment and the printer, including:

[0028] An instruction receiving module 1 for intercepting the printing instruction sent by the relay protection device to the printer;

[0029] A data forwarding module 2 for forwarding the print data sent by the relay protection equipment to the printer to the management equipment;

[0030] A communication protocol interface conversion module 3 for converting the print command of the relay protection device into the first data protoc...

Abstract

The invention provides a printing transmission data acquisition device for power system relay protection equipment, which is matched with management equipment and is arranged on a data line through which the relay protection equipment is connected with a printer. The printing transmission data acquisition device comprises a command receiving module for intercepting a relay protection equipment printing command, a data forwarding module for forwarding relay protection equipment printing data to the management equipment, a communication protocol interface conversion module for converting between the printing command and a data protocol, a printing control module for outputting management equipment printing data when the printer is started and the management equipment printing command is obtained, and a single-chip microcomputer. Through implementation of the embodiment of the invention, the relay protection equipment printing data can be relayed onto the management equipment, and the storage, calibration and edition of the printing data by the management equipment can be realized.

Description

technical field [0001] The invention relates to the technical field of printing and transmission data collection of relay protection equipment, in particular to a device and method for collecting printing and transmission data of relay protection equipment in a power system. Background technique [0002] With the development of the power system, there are more and more relay protection devices in the power system, and the printed data obviously increases and needs to be saved. At present, the data printed by the relay protection equipment of the power system are all stored in paper form. The disadvantages are: 1. The print data can only be stored in the local relay protection equipment, and the printing efficiency of paper is low and the cost is high; 2. The proofreading and editing of print data can only be done on the local relay protection device, but cannot be done on other devices. Contents of the invention [0003] The technical problem to be solved by the embodimen...
