The invention discloses an MEMS galvanometer scanning control system of a multi-transmitting single-receiving mirror laser radar. The MEMS galvanometer scanning control system at least comprises an MEMS galvanometer scanning control unit and a galvanometer scanning control unit, the system comprises an FPGA master end, an FPGA slave end, a drive circuit, an MEMS galvanometer, a drive control part,a photoelectric conversion module, an amplification shaping module and a plurality of lasers. The driving circuit, the driving control part and the amplifying and shaping module are respectively connected with the FPGA slave end, and through the structural arrangement of the laser thunder control system, a plurality of laser emitting channels are converted into a laser receiving and emitting light path. The problem that continuous work of laser emission in traditional equipment is difficult is avoided. Multiple paths of light sources with the same wavelength are converged into one incident channel to be emitted in tu
