In fact, the whole station instrument is a comprehensive point of the standards and the latitude and weft meter, the ranging meter+measurement software. Its appearance can be said to greatly improve the work efficiency of the measured personnel.In addition to the latitude and weft meter and the standard (cannot completely replace the level instrument, the accuracy of the level of the standard measurement of the standard is that any other instrument cannot be replaced), there are data collection and engineering samples! The following editors introduce relevant information!
How to use the whole station instrument
1. Preparation before measurement (1) The installation of the battery (note: the battery needs to be sufficient before measuring) ① Put the guide block at the bottom of the battery box into the guide hole of the battery.② Press the top of the battery box until I hear the sound of "click".③ Press the unlock button down and remove the battery.(2) Positioning of the instrument ① Select one point on the experimental venue as a measurement station, and the other two points as the observation point.② Place the whole station instrument at the point, and the whole level.③ Place prism at two points.(3) Settings of vertical disk and horizontal disk indicators ① Vertical disk index settings.Remove the vertical disk brake button and turn the telescope vertically for a week (the telescope is on the left, when the objective mirror passes through the horizontal plane), the vertical disk indicator is set.Then he heard a sound and showed the vertical angle.② Horizontal disk index settings.Loose the horizontal brake spiral, rotate 360, and the horizontal disk indicator is automatically set.Then there was a sound, and the horizontal angle was displayed at the same time.At this point, the vertical disk and horizontal disk indicator has been set.Note: Whenever the power supply is turned on, the indicator must be reset.(4) The focus of focusing and accurate targets is the same as the average latitude instrument. Pay attention to eliminate vision.
2. angle measurement (1) First determine whether it is at the angle measurement mode from the display. If not, the operation is converted to the distance mode.(2) Aiming at the left target A at the left, press the zero key, so that the horizontal disk reads is displayed at 0 ° 00′00 〃, rotating the quasi -in -line of clockwise, aiming at the right target B, and the reading read number.(3) The same method can be observed on the disk.(4) If the vertical corner is measured, you can read the display reading of the vertical disk while reading the horizontal disc.
3. Follow measuring (1) Set the prism constant in the instrument before setting up the normally number of prism, and the instrument will automatically correct the measured distance.(2) Set atmospheric corrective value or temperature, and air pressure value The spread of the transmission in the atmosphere will change with the temperature and air pressure of the atmosphere. 15 ° C and 760mmHg are a standard value of the instrument settings. At this time, the atmosphere is corrected to 0PPM.In actual measurement, you can input temperature and air pressure value. The whole station will automatically calculate the positive value of the atmosphere (can also directly input the atmospheric correction value), and correct the ranging results.(3) The height of the measuring instrument, the prism height and enter the full station instrument (4) The distance between the target prism at the measurement of the target prism, the distance between the distance is measured, and the distance, flat distance, and height difference are displayed when the distance is completed.HD is a horizontal distance and VD is a tilt distance.The ranging mode of the whole station has three types: precision measurement mode, tracking mode, and rough test mode.The precision measurement mode is the most commonly used rangefront mode. The measurement time is about 2.5s, and the minimum display unit is 1mm; the tracking mode is often used to track the mobile target or put the sample. The minimum display is generally 1cm, each time the range is about 0.3 about 0.3S; Rough measurement mode, measurement time of about 0.7s, minimum display unit 1cm or 1mm.When a distance measurement or coordinate measuring, you can select different ranging modes at the Field mode (Mode) key.It should be noted that some models of the whole station instrument cannot set the height of the instrument and the prism height when the distance is measured. The high difference displayed is the height difference between the horizontal axis center and the center of the prism.
4. Coordinate measurement (1) Set the three -dimensional coordinates of the measurement site.Set the three -dimensional coordinates of the test site.The readings of the horizontal disk of the back -view direction after setting the viewpoint after setting are then set.When the coordinates of the viewpoint after setting are set, the entire station will automatically calculate the direction angle of the direction of the direction after the whole station, and set the horizontal disk reading of the back -view direction to its orientation angle.(2) Set the frequent number of prisms.(3) Set atmospheric correction or temperature, gas pressure value.(4) The height of the instrument, the height of the prism and enter the whole station instrument.(5) Standard the target prism, press the coordinate measurement key, start the range of the whole station and calculate the three -dimensional coordinates of the display point.
Full station instrument
The technical indicators consider whether the technical indicators and accuracy meet the requirements of the use of use of the project content, technical design requirements, owners, supervision requirements, etc.And battery working hours will have a greater impact on users.
There are many, practical and perfect instruments that can be competent for surveying and mapping projects with large and perfect and perfect operation procedures. At the same time, the operation interface of the instrument should be simple, convenient, and humane. It should be easy to operate like a mobile phone.Various tips, convenient entry coding and so on.
Considering that many people do not care about this problem, they think that a spare battery can be solved.There are dozens of points of bad battery testing. What can two pieces be available? Where can I find sockets on the mountains and mountains? In addition, the battery of the entire station instrument is expensive, ranging from several hundred yuan to thousands of yuan.Once some models of instrument manufacturers are not produced, it is troublesome.
The after -sales service instruments after -sales service instruments are also an important factor that must be considered. Domestic full -bodies have a congenital disadvantage. Generally, the imported whole station instrument is maintained for thousands of yuan. In addition, if the instrument warranty period is long, it is also for users.Very affordable.
Choosing a brand full -bodant instrument is more special. It requires comprehensive considerations such as accuracy, stability, processing process and other factors. Good materials can ensure stable performance. Precision processing technology can ensure the accuracy of the instrument.It is a fine buckle, which can prevent the loosening of the screws caused by various vibrations. It is such a detailed anti -rust and dust, and the parts do not loosen the parts to ensure the stability of the instrument.
The meaning of the entire station instrument accuracy
The accuracy identification of the entire station instrument is (A+BPPM × D) mm: A, which represents the fixed error of the instrument, is mainly caused by the measurement error of the instrument with constant number, the intermediate error, the measuring error, the fixed error and the fixed error and the fixed error andThe measuring distance has nothing to do.That is, no matter how far the actual distance is measured, the whole station will have a fixed error that is not greater than the value.BPPM × D kilometer represents the proportional error. The B is the proportional error coefficient. It is mainly caused by the frequency error of the instrument and the atmospheric refractive index error.PPM is one -million -in -one, which is MM, which means one millionth.D is the distance value of the actual measurement of the whole station or ranging meter, and the unit is KM.
With the changes in the actual measuring distance, the proportion error part of the instrument changes in proportion.For example, when the distance is 1km, the proportion error is BMM.For a whole station or ranging instrument with a ranging accuracy of (1+2PPM × D) mm, when the measurement distance is 1 kilometer, the measuring accuracy of the instrument is 1mm+2ppm × 1 (km) = 3mm, and 3mm, and 3mm.In other words, the whole station measuring distance is 1km, and the maximum rangefinder error is not greater than 3mm. In particular, the nominal ranging accuracy is the concept of one error limit in one middle.The ranging error must not exceed the nominal ranging accuracy provided by the manufacturer.
