The invention discloses an overload starting device which mainly solves the problem that in the prior art, reliability is poor when acceleration is measured and overload judgment is carried out. The device comprises an upper cover, a circuit board, a base support, a base and an aviation plug interface, the circuit board is fixed on a mounting support, the upper cover is fastened with the base support, the aviation plug interface is fixed on the mounting support and connected with the circuit board, and an accelerometer, a signal processing module and a power supply unit are integrated on the circuit board. A signal processing module is divided into three paths, a signal acquisition unit of each path acquires acceleration signals sent by an accelerometer, and the acceleration signals are transmitted to a micro-processing unit and a signal filtering unit to be subjected to validity judgment and filtering respectively and then output to a temperature compensation unit to be subjected to temperature compensation. And under the condition that two or three paths of compensated signals reach a starting threshold value and a pulse width, an overload starting signal is transmitted to an upper computer through a serial port communication unit. The method improves the data accuracy and reliability, and can be used for aircraft overload alarm and emergency system starting.
本发明公开了一种过载启动装置,主要解决现有技术在测量加速度并进行过载判断时可靠性差的问题。其包括上盖、电路板、底座支架、底座和航插接口,电路板固定在安装支架上,上盖与底座支架紧固,航插接口固定在安装支架上并与电路板连接,电路板上集成有加速度计、信号处理模块和供电单元。其信号处理模块分为三路,每一路的信号采集单元采集加速度计发送的加速度信号,传输给微处理单元及信号滤波单元分别进行有效性判断和滤波后,输出给温度补偿单元进行温度补偿,三路补偿后的信号在有两路或三路信号达到启动阈值和脉宽的情况下,通过串口通信单元向上位机传输过载启动信号。本发明提高了数据准确性和可靠性,可用于飞行器过载报警和应急系统启动。
