Direct current system board card replacement device

The utility model provides a direct current system board card replacing device which comprises a human-computer interface computer, a 10-slot 3U-specification slot and a power supply conversion module. The 10-slot 3U-specification slot is connected with the human-computer interface computer; and the power supply conversion module is respectively connected with the human-computer interface computer and the 10-slot 3U-specification slot. According to the utility model, after a board card to be replaced is installed in a 10-slot 3U-specification slot, the power supply conversion module is switched on, and parameter information of new and old board cards can be automatically compared by utilizing a human-computer interface computer, so that the risk of manually checking information is avoided. 本实用新型提供了一种直流系统板卡更换装置，包括：人机界面电脑、10槽位3U规格插槽和电源转换模块；10槽位3U规格插槽，与所述人机界面电脑连接；电源转换模块，分别与所述人机界面电脑和所述10槽位3U规格插槽连接。本实用新型可将待更换的板卡安装至10槽位3U规格插槽后，接通电源转换模块，就可以利用人机界面电脑自动比对新旧板卡参数信息，避免了人工核对信息的风险性。
