An agricultural unmanned harvester remote smart control system, comprising a mechanical locomotion steering control system (1), a mechanical harvesting control system (2) and a wireless video surveillance system (3). The mechanical locomotion steering control system (1), the mechanical harvesting control system (2) and the wireless video surveillance system (3) are provided with a power supply module (4), the power supply module (4) is electrically connected to a voltage regulator (5), and the voltage regulator (5) is respectively electrically connected to a controller one (101), a controller two (201), a controller three (301) and a central processor (6). The agricultural unmanned harvester remote smart control system achieves the effects of unmanned harvester steering control, remote video surveillance and remote unmanned harvester control, effectively prevents the problem of disordered unmanned harvester electrical device operating voltages, and thereby solves the problem that agricultural machinery harves
