Abstract:Laser demarcation device can provide horizontal and vertical datum, that is used in benchmark calibration of buildings and installation of mechanical and electrical equipment in the pump station.A new set of light calibration system for the laser demarcation device was developed to solve these shortcomings of traditional calibration systems on poor accuracy, adjust slowly and high influential artificial factors, on the basement of numerous light calibrating theories, methods and system. First, light calibration platform was designed, this platform used several servo motors to screw adjusting screws in and out so as to calibrate the straightness and verticality of lights, and also used linear CCD(charge-coupled device)to detect the straightness and verticality of lights, that realize detection of lights. Then, based on the fuzzy PID(proportion integration differentiation)controlling method, a closed loop control system for light calibration, that adjusts light quickly, the dynamic balance performance is good to the process of light calibration. Experiments show that the process of light calibration is smooth and fast, the straightness and verticality of lights can be controled within ±1 mm/5 m, meet the requirements of the factory. This system is easy to operate, and is more efficient, and compared with the traditional way of manual adjustment, The light calibration equipment with high precision, adjusting quickly, low labor intensity.
