Virtual three-dimensional light beam barrier

The invention provides a virtual three-dimensional light beam barrier. The virtual three-dimensional light beam barrier comprises a waterproof, shading and constant-temperature box body (1) and is characterized in that the right end face of the waterproof, shading and constant-temperature box body (1) is sequentially provided with a light beam emitting lamp source A (2), a light beam emitting lamp source B (3), a light beam emitting lamp source C (4), a light beam emitting lamp source D (5), an orientation speaker A (6) and an orientation speaker B (7). The bottom of the waterproof, shading and constant-temperature box body (1) is provided with a device fixed to the ground (8) and an integrated electric appliance control box (9). The back of the waterproof, shading and constant-temperature box body (1) is provided with anti-collision reflective tape (10). A high-definition wide-angled camera and an exposure device (11) are arranged in the front face of the waterproof, shading and constant-temperature box body (1). The left end face of the waterproof, shading and constant-temperature box body (1) is provided with a running light beam (running the red light) bar sensing device (12). The virtual three-dimensional light beam barrier is capable of effectively overcoming the defects that lifting of an entity gear lever is slow, the maintenance cost is high, many collision disputes are generated, and the length is limited and has the advantages of being convenient to use, stable to work, long in service life and the like.
