2、performance of 3002LN, Leica 1202 TOPCON total station, data acquisition, data transmission, data format conversion, topographic map and engineering drawing. Among them, the data processing part is introduced in detail, which can be used as reference for comrades who have access to this kind of inst

3、rument for the first time.Gezhouba Dam Engineering Bureau, hydropower six Bureau, hydropower eight bureau and other units of surveying personnel reviewed this article, and put forward valuable suggestions, expressed thanks.Compared with the Leica 1202 3002LN 2. TOPCON total station performance2.1 30

4、02LN and Leica 1202 TOPCON total station of appearanceTOPCON GPT-3002LN Leica TPS1202Figure 1 3002LN and Leica 1202 TOPCON total station map2.2 - 3002LN GPT TOPCON total stationGPT - 3002LN has a dual optical system that is narrow beam measurement in prism free mode, ensuring that the point of sight

5、 is just the point to be measured. The other is the wide beam measurement in prism mode. Even under thermal scintillation conditions, the beam is very stable during long distance measurement, so it can provide precise measurement task.The instrument has a visible laser system with a red minimum poin

6、t laser pointer inside the instrument. But the red dot no Leica instrument red light, according to our test, you can see the red point 30 meters, can meet the needs of the large underground engineering surveying section.GPT3002LN long no prism ranging function, in terms of better weather conditions,

7、 we have the longest distance up to 1130 meters, for general slopes, long ranging will reach 500 to 700 meters, the observation control point pier, as far as 810 meters.The GPT3002NL series, like the GPT332W, are about the same size and operate roughly the same as the 332W. The difference is equippe

8、d with a large digital health disk and laser ranging system.The specific graphics can see Figure 1 left.2.3 Leica TPS1202 total station instrumentR1202 total station belongs to Leica TCR1200 series of total station instrument, and can be competent for all kinds of Leica TC type measurement tasks, su

9、ch as control survey, construction lofting, reference line lofting, topographic cadastral survey, etc.TCR1202 has three axis automatic compensation system, so that the measurement accuracy is safe and reliable.TCR1202 total station uses a unique absolute coding dial, image processing technology, a s

10、ingle measurement to read 60 lines of coding, to ensure high precision angle measurement; turn on the machine angle measurement, without initialization.TCR1202 series total station is equipped with many practical functions and applications, such as lofting, traverse survey, hidden point survey, refe

11、rence line lofting, DTM lofting, directional and elevation transfer, area calculation, and free station setting.TCR1202 total station features infrared ranging is coaxial with the telescope, in tracking mode, the speed of measurement will be higher.512K standard PCMCIA card is used to record data, i

12、nstrument memory, RS232 interface, and real-time output.2.4 TOPCON 3002LN and Leica 1202 two total station performance comparison1) Leica 1202 using a window display, friction brake unique, laser, observation can not reversing mirror (coordinate reversing mirror observations of exactly the same) and

13、 a series of measures to improve the observation speed, so the instrument efficiency was significantly higher than that of other types of observations. TOPCON 3002LN is developed based on TOPCON 332W, make local improvement based on the original operating system on the Topcon series, in a convenient

14、 and there is an obvious gap between the Leica 1202.2) Leica 1202 data transmission system and memory card (CF) is unique, Leica must find instrument configuration in taking damage, the user inconvenience.While the data transmission line, TOPCON total station all types of transmission, can be generi

15、c, no special CF card, so in terms of data transmission, TOPCON series total station more convenient.3) red laser, Leica 1202 in sighting the target a very bright, red laser point is very clear in the underground engineering on the wall; the red laser TOPCON 3002LN issued relatively weak, for underg

16、round engineering, more than 30 meters, the red laser is not clear. When there is no prism range finding, Leica 1202 has obvious advantages in finding target.4) in the prism free range, sometimes the line of sight needs to pass through the hole. For example, in underground engineering, the size of t

17、he formwork behind the steel mesh is observed. Leica 1202 generally as long as the laser line can pass through the steel mesh, red spots on the template appear, you can measure the coordinates of observation points. While the Topcon 3002LN total station only through more than 5 cm in diameter Kong S

18、hi (laser line requires the middle distance obstacle 2.5 cm, can measure the coordinates behind the laser point. Otherwise, the distance or coordinate measured is the distance from the station to the obstacle.5) prism free long distance, about 1 2 seconds a Leica 1202 observation points, and the Top

19、con 3002LN observations of a point about 7 8 seconds, the display immediately after the Leica 1202 sighting target, while the Topcon 3002LN takes 6 seconds after the show. In topographic survey, Leica 1202 has obvious advantages.6) according to our test, the observation conditions under good conditi

20、ons, the Leica 1202 prism far ranging up to 521 meters, TOPCON 3002LN prism ranging from the farthest reaches 1130 meters.3. outsourcing data acquisitionThe field data collection refers to the observation point with total station coordinate measurement, and the measurement results will be stored in

21、memory or total station on the CF card process. Data acquisition is an important step in digital mapping, usually in the measurement of required field sketch, and in the initial period of sketch marked typical objects, so that in the industry of digital mapping (and encoding mapping). The following

22、two data acquisition procedures are introduced respectively.3.1 the Topcon 3002LN field data collection3.1.1 creates a new file or calls an existing fileBuilding a file is the first step in digital mapping, that is, all measuring points within a fixed range of measurements must be stored in the same

23、 file. The establishment of a file in order to call and easy to use, with a fixed location, two measurements, also need to establish a different file name, such as the engineering measurement is to use the excavation at the same site before and after the two digital topographic map, calculate the fi

24、lling or excavation quantity. Generally, the name of the file is added to the date name with the place name, so it is convenient to use.A new file name must be created if the instrument is mounted on a new test site for data acquisition;If the original measurement is not finished, and now make addit

25、ional survey points, you can use the original file name.After setting up the instrument at the measuring station and taking the instrument high, press the POWER key to open the instrument, carry out horizontal and vertical rotation, and make the instrument enter the normal measurement mode:MENUPress
