Embodiment Construction

[0062] The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0063] A method for expanding the observation range of a vertical line collimator and simplifying the algorithm. The vertical line collimator includes a base plate 1, a left vernier caliper and a right vernier caliper. Two aiming needles 3, four installation holes 5 are opened on the base plate 1, and the base plate 1 is fixed on the ground through the four installation holes 5. It is characterized in that a downstream cursor caliper is added on the lower edge of the base plate 1, and a downstream cursor caliper, a left vernier caliper and a right vernier caliper are used. The three measured values ​​of the vernier caliper expand the observation range of the vertical collimator and simplify the conversion of the observation data of the vertical collimator.

[0064] Further, the upper edge of th...

Abstract

The invention discloses a method for expanding the observation range of a vertical line collimator and simplifying an algorithm. The vertical line collimator comprises a bottom plate (1), a left vernier caliper (9) and a right vernier caliper (8). A left vernier caliper (9) is arranged on the left edge of the bottom plate (1). A right vernier caliper (8) is arranged on the right edge of the bottomplate (1). Two sighting needles (3) are arranged at the upper edge of the bottom plate (1). The method is characterized in that a lower vernier caliper (10) is additionally arranged at the lower edgeof the bottom plate (1), the observation range of the vertical line collimator is expanded by adopting three measurement values of the lower vernier caliper (10), a left vernier caliper (9) and a right vernier caliper (8), and the conversion of observation data of the vertical line collimator is simplified. The effective observation range of the vertical line collimator is expanded exponentially,so that the measurement space of the vertical line collimator is greatly improved, and the situation that the installation position of the instrument needs to be moved again when the position of a vertical line body exceeds the observation range of the instrument due to large deformation amplitude of a dam is greatly avoided.

Description

technical field [0001] The invention relates to a method for enlarging the observation range of a vertical collimator and simplifying an algorithm, and belongs to the technical field of a vertical collimator. Background technique [0002] Monitoring the horizontal displacement of the dam by setting the vertical and inverted vertical line systems is an important means to control the safety status of the dam. The vertical line collimator is a common instrument used to manually observe the horizontal displacement of the dam. Its working principle is that the intersection point (corresponding to the vertical The coordinate value of the line body). [0003] The vertical line collimator is a common manual observation instrument in the field of dam safety monitoring. It is used to observe the position of the vertical or inverted line body, hereinafter referred to as "vertical line body", in the horizontal plane of the vertical line collimator. changes. It works as Figure 6 As s...
