Claim 3:
4. The multilayered rail guide vehicle system for use in three-dimensional planting in a plant factory according to claim 1, further comprising rescue devices (3) communicated with the electric control system (4), wherein the rescue devices (3) comprise two rescue devices, and are symmetrically arranged on both sides of the body of the rail guide vehicle, and are configured for lapping a body of another rail guide vehicle, so that the rail guide vehicle and the other rail guide vehicle are able to tow each other, so as to realize an emergency rescue operation of the rail guide vehicle; each of the rescue devices (3) comprises butt hooks (15) and butt slots (16);
the butt hooks (15) are rotatably arranged on both sides of the body of the rail guide vehicle in a forward direction, and the butt hooks (15) are able to horizontally extend to outside of the body of the rail guide vehicle; pawl parts are arranged at extending front ends of the butt hooks (15), and stop blocks are arranged at extending rear ends of the butt hooks (15);
the butt slots (16) are arranged on both sides of the body of the rail guide vehicle in a backward direction, and boss structures are arranged in the butt slots (16);
after the butt hooks (15) of the rail guide vehicle extend out, the butt hooks (15) of the rail guide vehicle are horizontally inserted into butt slots (16) of rescue devices of the body of the other rail guide vehicle; and after front ends of the pawl parts of the rail guide vehicle slide over the boss structures of the other rail guide vehicle, the stop blocks at rear ends of the rail guide vehicle are engaged with the boss structures of the other rail guide vehicle, so as to realize interlocking between the body of the rail guide vehicle and the body of the other rail guide vehicle.
