The invention belongs to the field of aviation power control, and relates to an auxiliary power device overrun detection device and a method. In order to effectively realize APU overrun detection protection control, the device comprises a rotating speed signal conditioning circuit, two independent hardware overrun detection circuits and a CPU software overrun detection unit, the rotating speed signal conditioning circuit is used for conditioning two paths of rotating speed signals and then inputs the two paths of rotating speed signals to the hardware overrun detection circuit and the CPU software overrun detection unit; when overrun of the auxiliary power device is detected by any one of the CPU software overrun detection unit and the hardware overrun detection circuits, an overrun control signal is output, a fuel supply electromagnetic valve of the auxiliary power device is controlled to be cut off, and it can be guaranteed that the auxiliary power device reliably and accurately achieves overrun protection control in a full-working envelope.

    本发明属于航空动力控制领域,涉及一种辅助动力装置超转检测装置及方法。为了有效实现APU的超转检测保护控制,该装置包括转速信号调理电路、两路独立的硬件超转检测电路和CPU软件超转检测单元;转速信号调理电路将两路转速信号进行调理后输入至硬件超转检测电路和CPU软件超转检测单元;当CPU软件超转检测单元和硬件超转检测电路任一检测到辅助动力装置超转时,输出超转控制信号,控制切断辅助动力装置的燃油供应电磁阀,能够保证辅助动力装置在全工作包线内可靠、准确的实现超转保护控制。
