轨道交通中的逆变电源主控板故障检测装置及其检测方法
摘要：
本发明公开了一种轨道交通中的逆变电源主控板故障检测装置及其检测方法。轨道交通中的逆变电源主控板故障检测装置，包括内部预置有用于判定被测逆变网电源实时状态并提供故障解决方案的检测系统的计算机，计算机依次通过485通信模块和模拟量输出模块连接至接口板，计算机还依次通过PLC工控板、继电器和开关电源连接至接口板，接口板用于连接被测逆变电源或充电机，被测逆变电源或充电机通过数据采集卡连接至计算机。解决了现有的客车逆变电源故障检修进行人工判断，费时费力，工作效率低下的问题。
摘要（英）：

The invention discloses an inverter power supply main control board fault detection device in rail transit and a detection method thereof. The inverter power supply main control board fault detection device in the rail transit comprises a computer which is provided with a detection system used for judging the real-time state of a to-be-detected inverter net power supply and providing a fault solution inside in advance; the computer is connected to an interface board by virtue of a 485 communication module and an analog quantity output module sequentially; the computer is also connected to the interface board by virtue of a PLC industrial control board, a relay and a switching power supply sequentially; the interface board is used for being connected with a to-be-detected inverter power supply or charger; and the to-be-detected inverter power supply or charger is connected to the computer by virtue of a data acquisition card. The inverter power supply main control board fault detection device can be used for solving the problems that as manual judgment is adopted in existing passenger car inverter power supply fault maintenance, both time and energy are wasted and working efficiency is low.
