The invention discloses a Doppler speed measuring device based on radio signals, which comprises a tripod, a speed measuring instrument is movably arranged on the tripod, an adjusting box body is arranged on the tripod, and a rotating piece is arranged in the adjusting box body. Compared with the prior art, the Doppler speed measuring device based on the radio signals can measure the road trend through a measuring assembly before a speed measuring instrument is installed, can measure the included angle between the transmitting end of the tachymeter and the direction perpendicular to the road direction through a rotating rod and a fixing block, then can adjust the transmitting end of the tachymeter to be perpendicular to the road direction, and on the basis, the mounting base is adjusted through the rotating piece, so that the placement position of the tachymeter is more accurate; and in the process of mounting the measuring assembly in the mounting base, the mounting seat is adjusted to be parallel to the road surface through the matching of the measuring assembly and the transmission part, so that the speed measurement precision is improved.

    本发明公开了一种基于无线电信号的多普勒测速装置,包括三脚架,三脚架上活动设置有测速仪,三脚架上设置有调节箱体,调节箱体内设置有转动件,此基于无线电信号的多普勒测速装置,区别于现有技术,能够在测速仪安装前,通过测量组件对道路走向进行测量,且能够通过转动杆和固定块测量出测速仪发射端与路面走向垂直方向的夹角,进而将测速仪发射端调整至垂直路面走向且以此为基准,通过转动件调节安装座使得测速仪的摆放位置更加精确,且在测量组件安装到安装座内的过程中,通过测量组件和传动件的配合调节安装座使其与路面走向平行,进而提高测速精度。
