Problems solved by technology

[0004] Since the deformation monitoring instrument needs to work continuously in the field for a long time, it faces the test of harsh environments such as strong wind, sand and dust, and low temperature. However, at this stage, there is no protection device that can protect the equipment without affecting its normal work.

Abstract

The invention relates to an optical protective cover suitable for field unattended deformation measurement. The protective cover is composed of an upper part and a lower part which are connected together through a PC board. The upper part comprises an upper top, an upper ring inner frame and an upper ring outer frame, wherein the upper top is connected together, and the upper ring inner frame and the upper ring outer frame are octagonal; the upper ring inner frame and the upper ring outer frame are respectively connected with the PC board; the lower part comprises a matching base which is fixed on the mounting stand column and is used for mounting a deformation measuring instrument, and a lower ring inner frame, a lower ring outer frame and a lower ring middle frame which are connected together; the lower ring middle frame is connected with the matching base; and the lower ring outer frame and the lower ring middle frame are respectively connected with the PC board. The optical protective cover is light, firm and easy to assemble, and can well meet the application requirements of field deformation monitoring equipment.

Description

technical field [0001] The invention relates to the field of surveying and mapping, in particular to an optical protective cover suitable for unattended deformation measurement in the field. Background technique [0002] The construction of the transportation hub from Qinghai to Lhasa is a lifeline project connecting the inland and Tibet. Subgrade settlement deformation is an important index to evaluate the stability of Qinghai-Tibet highway and railway engineering. For a long time, artificial level monitoring, as the most basic monitoring method for field deformation monitoring, is also the most reliable at this stage, and at the same time, it is also the most costly deformation monitoring method. [0003] With the advancement of science and technology, deformation monitoring is also taking steps towards automated monitoring. Unattended automated solutions have obvious advantages over manual observation: low cost, low manual interference error, high measurement accuracy, h...
