Online detection system and method for ignition circuit of floating system controller

The invention provides an online detection system and method for an ignition circuit of a floating system controller. The online detection system comprises an upper computer, a control module and a monitoring module. By online detecting the ignition circuit of the helicopter floating system controller, the function of inquiring whether the system is healthy or not in the air state and uploading parameters is achieved; when the ground state has a maintenance command requirement, on-off of detonation bridge wires of the helicopter floating device is checked under the condition that the maintenance switch is turned on; when that all the detonation bridge wires are disconnected is detected, ignition detonation is detected and output for ignition testing; the detection and maintenance cost is reduced, and the detection safety and the result reliability are improved. 本发明提供了一种漂浮系统控制器点火电路在线检测系统和检测方法，包括上位机、控制模块和监控模块；通过在线检测直升机漂浮系统控制器的点火电路，实现了在空中状态时查询系统本身是否健康的参数并上传的功能；在地面状态有维护命令要求时，在维护开关开启的情况下对直升机漂浮装置起爆桥丝通断进行检查；当检测到所有起爆
