Patent ID: 7916279

Claim:
A measuring system comprising: a measuring apparatus provided at an already-known point; a plurality of light-receiving apparatuses provided at measured points; and a main calculating apparatus for instructing the measuring apparatus and the light-receiving apparatus; the measuring apparatus comprising: a laser-beam-emitting section that rotates and emits both a standard-face-forming laser beam composed of two or more fan-shaped laser beams, of which at least one beam is inclined, and a distance-measuring light; an emission-direction detecting section for detecting the emission direction of the laser-beam-emitting section; a distance measuring section measuring a distance between the measuring apparatus and the light-receiving apparatus by receiving the distance-measuring light reflected by the light-receiving apparatus; and a wireless communication section for communicating measurement data with the light-receiving apparatus or with the main calculating apparatus, wherein the measurement data includes an angle detected by the emission-direction detecting section and a distance measured by the distance-measuring section; the light-receiving apparatuses each comprising: a reflector for reflecting the distance-measuring light in a direction of the measuring apparatus; a light-receiving section for receiving the standard-face-forming laser beam; a light-receiving side control arithmetic section for calculating an elevation angle to the measuring apparatus by light signals of the standard-face-forming laser beam which are received by the light-receiving section, and for calculating a height position by the elevation angle and the distance between the measuring apparatus and the light-receiving apparatus; and a light-receiving side wireless communication section for communicating the measurement data of the measured point with the measuring apparatus or with the main calculating section; the main calculating sections each comprising: a main wireless communication section for communicating with the measuring apparatus or with the light-receiving apparatus; and a main memory section for collecting and storing the measurement data that is measured by the measuring apparatus and by the plurality of light-receiving apparatuses.
