Open IGPS measuring system operating software on computer；
Step 3: arrangement IGPS measures network, and carries IGPS measurement network demarcate bar with equipment and measure net to IGPS
Network is demarcated, and is set up three-dimensional high-precision and is measured network；
Step 4: precision evaluation is carried out to three-dimensional measurement network, in the good measurement range of accessibility, and guarantees its survey
Accuracy of measurement is δ, and it is suitable for taking δ≤0.1mm；
Step 5: IGPS hand-held measuring appliance 37 is subjected to examination survey in measurement network, it is ensured that IGPS hand-held measuring appliance 37 exists
Visibility reaches 98% in three-dimensional measurement network；
Step 6: mounting and positioning device demarcate bar, as shown in fig. 6, to cooperative target universal threaded connecting interface, and high-ranking officers
Quasi- tool is arranged in measurement network, and wherein the length L1 Yu tracker of demarcate bar get the size of the length L2 of positioning device 27 ready
Tolerance value is Δ, i.e., | L1-L2 |≤Δ generally takes Δ=0.01mm；
Rapid seven: using the cooperative target for being mounted with positioning device demarcate bar, certain point on truing tool is measured, and
IGPS hand-held measuring appliance 37 is rotated along all direction in spaces (left, right, front and rear) and two diagonal lines, is held also along IGPS
37 main shaft of measuring instrument is rotated, and the calibration of positioning device is completed；
Step 8: to positioning device demarcate bar carry out precision evaluation, if precision reaches requirement, be changed to described point/draw
Line positioning device 19, otherwise repeatedly step 7；
Step 9: being aligned by measuring device measurement data, and by measurement data with gross data, evaluates alignment accuracy,
It meets the requirements, is then positioned, otherwise re-measured, then be aligned；
Step 10: the mobile positioning device being fixed together and IGPS hand-held measuring appliance 37 in measurement network work as positioning
When device is moved to system part position of positioning hole, by driven triggering device, inner slide 22 and marking pen 24 are jointly mobile at this time, in work
Part surface leaves the black dot that diameter is about 1mm, completes positioning, gets work ready.
A specific embodiment of the invention is described in conjunction with attached drawing above, but these explanations cannot be understood to limit
The scope of the present invention, protection scope of the present invention are limited by appended claims, any in the claims in the present invention base
Change on plinth is all protection scope of the present invention.
