The invention provides a dual-redundancy aircraft fuel tank low-oil-level warning system. The dual-redundancy aircraft fuel tank low-oil-level warning system mainly comprises a low-oil-level annunciator (1), a display device (2), an electromechanical management computer (3) and a main oil quantity measuring system (4). The low oil level annunciator (1) sends an alarm signal to the electromechanical management computer (3) when the oil level is lower than a preset value; the main oil quantity measuring system (4) measures the oil quantity of a main oil tank in real time and sends the oil quantity to the electromechanical management computer (3); the electromechanical management computer (3) synthesizes signals of the low-oil-level annunciator (1) and input signals of the main oil quantity measuring system (4), comprehensively analyzes and judges the signals and then sends display signals to the display device (2). The dual-redundancy aircraft fuel tank low fuel level alarm system is simple in principle, safe and reliable, can meet the use requirements of an aircraft in an actual flight state, and effectively improves the safety redundancy of the system.
本发明提供一种双余度飞机油箱低油面告警系统,主要包括低油面信号器(1)、显示装置(2)、机电管理计算机(3)和主油量测量系统(4)。低油面信号器(1)当油面低于预定值时发出告警信号给机电管理计算机(3);主油量测量系统(4)实时测量主油箱油量,发送给机电管理计算机(3);机电管理计算机(3)综合低油面信号器(1)的信号和主油量测量系统(4)的输入信号,综合分析判断后向显示装置(2)发出显示信号。该双余度飞机油箱低油面告警系统,原理简单、安全可靠,能满足飞机在实际飞行状态下的使用要求,有效提高系统的安全余度。
