The invention relates to the technical field of inspection unmanned aerial vehicles, in particular to an indoor inspection unmanned aerial vehicle with a stable ultra-wideband structure, which comprises a device body, a top block is arranged at the top end of the device body, four groups of mounting frames are arranged on the surface of the device body, and a supporting ring is fixedly connected to the surface of each mounting frame. A fan blade body is arranged on the surface of the supporting ring; and the mounting ring is fixedly mounted at the bottom end of the device body. According to the invention, through the ultra-wideband technology, the important problem which troubles the traditional wireless technology for many years and is related to the propagation aspect is solved, and the method has the advantages of insensitivity to channel fading, low power spectrum density of transmitted signals, low interception capability, low system complexity, capability of providing positioning accuracy of several centimeters and the like; the ultra-wideband is applied to close-range high-speed data transmission in the early stage, and in recent years, the subnanosecond ultra-narrow pulse of the ultra-wideband starts to be used for close-range accurate indoor positioning in foreign countries.
本发明涉及巡检无人机技术领域,具体为一种具有稳定超宽带结构的室内巡检无人机,包括:装置本体,所述装置本体的顶端设置有顶块,所述装置本体的表面设置有安装架,所述安装架设置有四组,所述安装架的表面固定连接有支撑环,所述支撑环的表面设置有扇叶本体;安装环,所述安装环固定安装在装置本体的底端。本发明通过超宽带技术解决了困扰传统无线技术多年的有关传播方面的重大难题,它具有对信道衰落不敏感、发射信号功率谱密度低、低截获能力、系统复杂度低、能提供数厘米的定位精度等优点,超宽带在早期被用来应用在近距离高速数据传输,近年来国外开始利用其亚纳秒级超窄脉冲来做近距离精确室内定位。
