The invention discloses an airborne comprehensive alarm system, and relates to the technical field of avionics airborne alarms, the airborne comprehensive alarm system comprises a control box and a main alarm lamp box, multiple alarm lamps are arranged in the main alarm lamp box, and a main control unit, a discrete magnitude acquisition circuit, a program and voice data storage unit, an RS422 bus communication circuit and a main alarm lamp box circuit are arranged in the control box; an ARM chip is adopted as a system control and data processing center, discrete alarm signals are collected through a discrete magnitude interface circuit, an RS422 interface circuit is used for receiving the RS422 alarm signals of an electromechanical management computer, analysis, judgment and processing of fault signals are completed through software, and the fault signals are sent to a server through a server. According to the alarm level, the confirmed fault is output to an alarm lamp box or is sent to an electromechanical management computer, a display and a built-in interphone through RS422, so that the operation speed is high, an instruction system is flexible, and the power consumption is low; the discrete alarm acquisition unit is standard in interface and good in anti-interference performance; connection lines are few, and reliability is high. And the designed interface is standard and has strong adaptability.

    本发明公开了一种机载综合告警系统,涉及航空电子机载告警技术领域,包括控制盒和主告警灯盒,主告警灯盒内设置有多重告警灯,控制盒内设置有主控单元、离散量采集电路、程序及语音数据存储单元、RS422总线通信电路以及主告警灯盒电路;本发明实现采用ARM芯片作为系统控制和数据处理中心,通过离散量接口电路采集离散告警信号,RS422接口电路用于接收机电管理计算机RS422告警信号,由软件完成对故障信号的分析、判断、处理,根据告警等级将确认的故障输出到告警灯盒或通过RS422发送至机电管理计算机、显示器,机内通话器,使得具有运算速度快、指令系统灵活、功耗低;离散告警采集单元接口标准,抗干扰性好;连线少,可靠性高。设计接口标准,适应性强。
