DEVICE FOR MEASURING POSITION OF BUILDING, ITS POSITION-MEASURING SYSTEM, METHOD FOR MEASURING POSITION OF BUILDING, AND CONSTRUCTION-LIMIT JUDGING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a position measuring device and a position measuring system which are suited to measurement of the clearance between a building to be built in the periphery of a track for electric car and a track rail and can improve the operability and practicality. ;SOLUTION: When an operator turns on a power supply switch of an operation part 3 in the position measuring device 1 so as to supply a specified electric power from a power supply part 4, a CPU 2 indicates the state of inside of the device 1 in an indication part 5. When the operator operates the part 3 to instruct measurement, the CPU 2 issues a measurement start command to a distance measurement part 6, and the part 6 measures a distance to a point to be measured of a building according to a laser light reflected on the building. The CPU 2 calculates a distance thereto, especially height and clearance of construction limit thereof, according to the measured data from the part 6, and indicates the result in the part 5 automatically.;COPYRIGHT: (C)1998,JPO
