The invention discloses a multi-rotor aircraft broken propeller detection device which comprises an electronic tag arranged in a propeller blade and a reader-writer arranged on an arm, the electronic tag comprises a read-write coil and a detection conductor, the detection conductor is arranged from the propeller root to the propeller tip of the propeller blade, the two ends of the detection conductor are electrically connected to the read-write coil, and the read-write coil is electrically connected with the reader-writer. The read-write coil and the detection conductor form a circuit loop, the detection conductor is arranged from the blade root to the blade tip of the blade, and the detection conductor and the read coil are connected in series to form the circuit loop, so that when the blade is broken, the detection conductor is broken along with the breakage of the blade, and the circuit loop is broken; and when the information cannot be read by the reader-writer on the machine arm through the reading coil, the paddle breaking phenomenon can be judged.

    本发明公开了一种多旋翼航空器断桨检测装置,包括设于桨叶内的电子标签以及设于机臂的读写器,电子标签包括读写线圈和检测导体,检测导体沿桨叶的桨根至桨尖布置,且检测导体的两端电连接于读写线圈,读写线圈和检测导体构成一电路回路,检测导体沿桨叶的桨根至桨尖布置,且由于检测导体和读取线圈串联连接以构成一电路回路,当桨叶断裂,检测导体会随着桨叶断裂而断开,导致电路回路断路,机臂上的读写器无法通过读取线圈读取到信息,即可判定出现断桨现象。
