Description

technical field [0001] The invention relates to a laser sensor, in particular to a high-precision laser sensor with distance measuring function and a laser control system using the laser sensor. Background technique [0002] At present, laser control systems are widely used in fields such as farmland plowing, building construction, and road construction for precise leveling operations. The system uses the rotating laser signal as the reference plane, uses the laser sensor fixed on the shovel to receive the laser reference plane signal, detects the elevation deviation of the shovel, and uses the deviation signal to control the hydraulic drive system to adjust the lift of the shovel, so as to achieve accurate Leveling work. [0003] In order to realize the precise leveling operation of the laser control system, CN102506834A discloses a laser receiver, which includes a laser receiver circuit and a host for identifying the position of the laser signal. CN203190976U discloses a...

Problems solved by technology

At present, there are many problems and deficiencies in the actual application of the existing products: the detection error of the photoelectric detector to the laser signal is relatively large; the receiving distance cannot be detected in real time during the leveling operation, so that the operator cannot judge whether the position exceeds the range of the laser sensor. working range, resulting in leveling accuracy can not be guaranteed
