Title:
DIRECTION SETTING WORKING SYSTEM FOR GUIDE LASER BEAM
Document Type and Number:
Japanese Patent JP3892290
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a direction setting working system in the horizontal direction of a guide laser beam.
SOLUTION: The system uses a guide laser beam irradiator 20, a first GPS unit 75 for detecting a reference horizontal direction position of the irradiator 20 and a pole 81 having a second GPS unit 76 for detecting the horizontal position. The first GPS unit 75 detects the reference horizontal direction position of the irradiator 20, the second GPS 76 of the pole 81 erected at a first position 83 detects a first horizontal direction position to specify a desired direction Z1 of irradiating from the reference horizontal direction position and the second GPS 76 of the pole 81 erected at a second position 80 detects a second horizontal direction position to specify an actual irradiating direction Z2 from the reference horizontal direction position. Thus an angle &phiv of the desired irradiating direction making with the actual irradiating direction Z2 is obtained to set a guide laser beam P in the desired irradiating direction Z1, based on the angle &phiv .
