Research on an improved laser-controlled land leveling system

An improved laser-controlled land leveling system is discussed with the purpose of designing the system effectively and low-cost. The system is composed of three parts. A laser emitter can produce slopes. A laser receiver can receive the laser beam and filter the noisy light, and its incepting diameter is extended to about 400 m. A controller can process the altitude signals and control the hydraulic system for the leveling scraper. Many experiments have been done in different places, and the standard deviation of relative height is close to 2 cm after leveling. Experiments have shown that the system is effective and steady, and the cost is obviously decreased.
