Title:
レーザ測定システムに於ける省電力制御方法及びレーザ測定システム
Document Type and Number:
Japanese Patent JP4920467
Kind Code:
B2
Abstract:
A power-saving control method in a laser measuring system, which comprises a laser rotary irradiation device for forming a laser reference plane by projecting a laser beam in rotary irradiation and a photodetection device for carrying out position measurement by receiving the laser beam, comprising a step of detecting using status of the photodetection device by the photodetection device, a step of selecting steady operation or power-saving mode based on the detection of using status, a step of transmitting a power-saving mode transition instruction to the laser rotary irradiation device by the photodetection device when the power-saving mode is selected, a step of receiving the power-saving mode transition instruction by the laser rotary irradiation device, and a step of executing power-saving control.
