摘要： A control system is disclosed that controls the position of a grading implement of a construction machine according to a site plan. The control system has three basic components: a stationary tracking station, a computer connected to the tracking station, and an implement controller attached to the construction machine. The tracking station measures a distance and an azimuth (horizontal) angle to a remote target located on the construction machine and communicates that position information to the computer. The computer consults a stored site plan to determine what elevation is desired at that position and calculates a corresponding zenith (vertical) angle, and communicates the desired zenith angle to the tracking station. The tracking station in turn positions a zenith-reference laser beam at the desired zenith angle. The implement controller senses the zenith-reference laser beam and adjusts the grading implement relative to the zenith-reference laser beam until its desired position is obtained.

The survey unit is equipped with a finished-height data drive mode in which the laser beam is rotated in a vertical direction by a rotation unit so that the height of the laser beam at the horizontal coordinate position becomes a height from the determined finished plane. The construction machine is provided with a control unit for controlling the ground leveling implement so that it reaches the finished-plane height, based on a position at which the laser beam is received on the laser sensor, and also controlling the ground leveling implement, based on the demodulated construction information.

摘要： A light image of a scale, which bears length or angle information recorded in the form of a bright and dark bit pattern, is projected onto the light receiving surface of a storage effect type sensor, whereby a charge pattern data corresponding to the projected image is formed. Before the regular read-out of the charge pattern data thus formed from the sensor, the sensor is scanned at least once at a higher scanning frequency than the frequency for the regular data read-out. From the data thus read out, read-out data that obtained in the absence of illumination light is subtracted, and the resultant data which is free from error component is processed to obtain a final measurement of the length or angle.

摘要： In a light-wave distance meter, a light source device emits reference modulated light beams from multiple spatially-separated light emitting areas, an optical means radiates a light beam derived from the multiple modulated light beams to the target of measurement, a light beam reception means receives the reflected return light beam from the target and converts it into an electrical pulse signal, and a distance measuring means calculates the distance to the target based on the time difference between the light beam emission and the return light beam reception. The low coherence and high intensity light beam produced by the light source device enables the extension of the maximum measurable distance.
