7. The intelligent transportation multi-splice multi-dimensional omni-directional scanning millimeter wave radar of claim 1, wherein: the main control board is electrically connected with the electronic compass, and the main control board is internally provided with a gesture module which is used for detecting whether the equipment is in a correct gesture and giving out an abnormal gesture alarm.
8. The intelligent transportation multi-splice multi-dimensional omni-directional scanning millimeter wave radar of claim 1, wherein: and a power supply module is arranged in the main control board.
9. The intelligent transportation multi-splice multi-dimensional omni-directional scanning millimeter wave radar of claim 1, wherein: the communication module can adopt any one or the combination of more than two of a 4G communication module, a 5G communication module, a WIFI communication module or a wired network communication module.
10. The intelligent transportation multi-splice multi-dimensional omni-directional scanning millimeter wave radar of claim 1, wherein: the main control board is provided with a local storage module.
