The invention relates to the field of collision detection of unmanned aerial vehicles, in particular to a collision detection device and method of a spherical unmanned aerial vehicle, the device comprises a spherical protective shell and an airborne host arranged on an unmanned aerial vehicle body, and the unmanned aerial vehicle body is located at a middle cavity of the spherical protective shell. The appearance of the spherical protective shell is a structural body formed by interweaving warps and wefts, meanwhile, a circuit groove is dug in the interwoven structural body, and a passive pvdf piezoelectric material is embedded in the groove; a data signal acquisition module and a ros system are arranged on the airborne host, the passive pvdf piezoelectric material is in signal connection with the data signal acquisition module through a wire, the data signal acquisition module acquires a collision signal of the unmanned aerial vehicle in real time and amplifies the collision signal, and then the data is transmitted to the ros system through the STM32 single-chip microcomputer for filtering and collision analysis. The method can be widely applied to the field of unmanned aerial vehicles and has high application value.

    本发明涉及无人机碰撞检测领域,尤其涉及一种球形无人机的碰撞检测装置和方法,该装置包括球形保护外壳以及设置在无人机本体上的机载主机,无人机本体位于球形保护外壳的中间空腔处,其特征在于,所述球形保护外壳的外形呈经线纬线交织的结构体,同时在交织的结构体内挖设线路槽,并在槽内埋设有无源pvdf压电材料;所述机载主机上设有数据信号采集模块、ros系统,所述无源pvdf压电材料通过导线信号连接所述数据信号采集模块,所述数据信号采集模块实时采集无人机的碰撞信号并进行放大处理,后通过STM32单片机将数据传递给ros系统进行滤波处理及碰撞分析。本发明可以广泛应用于无人机领域,具有较高的应用价值。
