Automatic board card detecting device of direct current power transmission control protective system

Abstract

The invention discloses an automatic board card detecting device of a direct current power transmission control protective system, which comprises a work station, a detecting host and a detecting chassis; the work station comprises a display and a host for issuing a control command to the detecting host, and receiving the detecting outcome from the detecting host; the display displays a man-machine interface under the control of the host; the detecting host comprises a first power supply board card, a host board card and a first communication board card; the host board card controls the detecting chassis to perform corresponding detecting according to the command of the work station and returns the detecting outcome to the work station; the first communication board card is upwards communicated with the work station and downwards communicated with the detecting chassis under the control of the host board card; and the detecting chassis comprises a second power supply board card, a second communication board card and a detecting assisting board card connected with a detected board card by an interface wire harness. The automatic board card detecting device of the direct current power transmission control protective system can automatically and fully detect the hardware, software and function of the plug-in board card, and meets the various requirements on reliability, safety and economy.

Description

technical field [0001] The invention relates to an automatic board card detection device, in particular to a device designed for a direct current transmission control and protection system and capable of comprehensive automatic detection of software, hardware, function and communication status of a plug-in board card. Background technique [0002] DC transmission technology is a power transmission technology that realizes AC / DC conversion by means of high-power semi-controlled power electronic devices (such as thyristors) or fully-controlled power electronic devices (such as IGBT, IGCT, etc.), and is a power transmission that requires real-time control. Way. The DC transmission control and protection system responsible for its control and protection functions has the following characteristics: (1) a complex all-digital large system, relying on high-speed field bus and Ethernet to realize communication; (2) adopting a decentralized and distributed structure, using plug-in boa...

Problems solved by technology

However, this detection method can only rely entirely on manual observation, and can only detect whether the board under test can be powered on normally, whether the application program can be downloaded and run normally, etc., but cannot judge components such as communication, measurement, control, etc. Whether the function is normal, so its detection content and effect are very limited, which may bury hidden dangers for subsequent system operation
