(3)Measuring appratus is high, prism is high and inputs total powerstation.
(4)Range measurement
Target prism centers are sighted, press ranging key, range measurement starts, and ranging show oblique distance, put down away from, the discrepancy in elevation when completing.
The distance measurement mode of total powerstation has fine mode, tracing mode, three kinds of bigness scale pattern.Fine mode is the most frequently used survey Away from pattern, time of measuring about 2.5S, minimum unit of display 1mm;Tracing mode, it is usually used in continuous when tracked mobile target or setting-out Ranging, minimum display are generally 1cm, each ranging time about 0.3S;Bigness scale pattern, time of measuring about 0.7S, minimum display are single Position 1cm or 1mm., can be by distance measurement mode in range measurement or measurement of coordinates(MODE)Key selects different distance measurement modes.
2. measurement of coordinates
(1)Set the three-dimensional coordinate of survey station point.
(2)The horizontal limb reading of apparent direction is its azimuth after setting the coordinate of backsight point or setting.When setting backsight During the coordinate of point, the azimuth of apparent direction after total powerstation can calculate automatically, and after setting apparent direction horizontal limb reading as it Azimuth.
(3)Prism constant is set.
(4)Atmospheric correction value or temperature, atmospheric pressure value are set.
(5)Measuring appratus is high, prism is high and inputs total powerstation.
(6)Target prism is sighted, presses measurement of coordinates key, total powerstation starts ranging and calculates the three-dimensional coordinate of display measuring point.
As can be seen here, total powerstation instrument height is very important underlying parameter, and the precision of instrument height is adjusted the distance with coordinate etc. The measurement accuracy of fundamental influences very big.
The measuring method of existing instrument height mainly has the following two kinds.
(1)Steel tape mensuration
Most traditional instrument height measuring method.Instrument height is vertical range of the measurement control point to centre, is directly surveyed Amount is not because being flat relation of plane, and absolute being error, steel tape measurement error is larger in addition.
(3)Laser optical method
The amount of laser light point function having using instrument itself measures, although laser measurement precision is all higher than above two side Method, but because hot spot is beaten inside crosshair rather than datum mark peak, systematic error is brought, overall measurement accuracy is limited System.
The measurement accuracy of above measuring method is grade, the inapplicable occasion for needing fine instrument high parameter.
