Communication apparatus connection.Display can intuitively show measurement and result of calculation.
Preferably, the display of the preceding ruler and rear ruler is respectively disposed on the side at two 1.5 meters of levelling rods, convenient for seeing
See the content of display.
Preferably, the GPS positioning device on the spirit level is fixed in the positioning box of spirit level.
Above-mentioned GPS auxiliary precise leveling equipment is realized according to following steps during quick obtaining precise leveling
Relative position between spirit level, front and rear measurement ruler：
(1) when preparing to measure, instrument and equipment is all turned on GPS functions and communication function；
(2) coordinate vector of any two points can be quickly calculated using GPS positioning device, is calculated：Front and rear ruler away from
From and height difference, the distance between instrument and front and rear ruler and height difference；
(3) when starting to measure, rear ruler point position is fixed, and spirit level and preceding ruler move forward；At this point, determined using GPS
Position equipment can calculate the relative position information between spirit level and front and rear ruler in real time：Real-time display distance on spirit level and measurement ruler
The distance of front and rear ruler and instrument are the same as the height change of rear ruler point；
(4) after spirit level location determination, rear ruler position can quickly determine OK range, Ran Houfang according to location information
Put levelling rod；
(5) the preceding ruler of last survey station of precise leveling and the position of rear ruler are fixed, and spirit level can be according to phase
OK range is quickly determined to location information, then spirit level is disposed to be observed.
The utility model compared with prior art the advantages of be：It (1) can be between quick obtaining spirit level, front and rear measurement ruler
Range information, can be with fast erecting instrument and equipment；(2) can rough height difference between quick obtaining spirit level, front and rear measurement ruler, be
Judgement sets whether station meets code requirement offer Informational support；It (3), can be according to GPS positioning information when losing or being stolen
It quickly looks for, reduces loss.
