How to maintain surveying and mapping instruments like Shenyang total station

A Shenyang total station is tens of thousands of dollars cheaper, hundreds of thousands of dollars more expensive, the protection is not good or bad, everyone has heartache. How to maintain our instruments during work?
Now, in the field of surveying and mapping, there are more and more types of surveying and mapping instruments, and the structure of the instruments has become more and more complicated and more sophisticated. However, the working environment of surveying and mapping instruments is inevitably subject to corrosion by elements such as wind and rain, sun, dust, and moisture. A Shenyang total station is tens of thousands of dollars cheaper, hundreds of thousands of dollars more expensive, the protection is not good or bad, everyone has heartache. How to maintain our instruments during work?

Total Station in Shenyang

Let's talk about the room first:

The room where the instruments are stored should be boring, bright, ventilated, and the room temperature should be stable at about 10-16 degrees. Prepare fire fighting equipment (liquid carbon dioxide and carbon tetrachloride fire extinguishers) indoors. It is inevitable that the instrument will be corroded, and there should be no acid or alkali in the room. The box where the instrument is stored must also be boring, and one or two bags of moisture-proof agent can be placed in the box. The instrument should be in a wooden cabinet or on a rack, and should not be placed directly on the ground. Do not lean on the tripod at will to prevent deformation.

Let's talk about outdoor process protection:

When removing the instrument, pay attention to the orientation of the instrument in the box to ensure that the instrument can be placed in the original orientation after use. Do not lift the instrument with one hand when taking it out, and support the base with one hand. After removing the instrument, lift the instrument upright and place it on a tripod. After the tripod is set up firmly, put the instrument on and make sure that the instrument is properly connected to the tripod. During the measurement, the observer cannot leave the instrument. In the wild, use an umbrella to cover the sun, rain, etc., and you must prevent flying stones from hitting the instrument. The instrument case should not be seated to prevent deformation of the case and prevent the instrument from being put in, or the instrument in the case may be crushed. Also, when it rains or snows, there may be water on the instrument. Do not scrub at will, so as not to scratch the mirror surface, or damage the paint. Instrument operating temperature When the ambient temperature changes greatly, special measures need to be taken, for example, when the instrument goes down the well in winter (low outdoor temperature in winter and high downhole temperature), many drops of water will condense on the instrument. If the instrument is not tight, it will seriously affect The imaging quality is even scrapped.

Finally, I want to talk about a simple point of negligence, which is the protection of a tripod. In the daily use of the tripod, it is simply exposed to the sun, rain, and bumps. The tripod should be coated with ground wax to prevent moisture from penetrating the wood and deforming it. Often, tripod problems cause the instrument to break.
