Controllable light-emitting prism device

Abstract

The invention discloses a controllable light-emitting prism device. The controllable light-emitting prism device comprises a prism body with a laser receiving part, an illumination device arranged outside the prism body and used for assisting illumination, and a light control system for adjusting the illumination state of the illumination device, wherein the light control system comprises a processor and a laser induction sensor connected with the processor; after the laser receiving part receives laser beam information emitted by a total station and transmits the laser beam information to the processor by the laser induction sensor, the processor controls the illumination device to convert the illumination state; the illumination of the illumination device can guide the total station to rapidly position the position of the prism device under the condition that the visibility is low, so that measurement work can be conveniently carried out in a relatively dark environment; and meanwhile, the illumination device can realize the conversion of the illumination states before and after the prism body receives laser under the control of the light control system, so that the prism device and the total station have information interactive feedback. The defects in an existing measurement technology can be made up, and the smooth and efficient implementation of the measurement work under the condition that illumination environment conditions are bad is guaranteed.

Description

technical field [0001] The invention relates to a prism device suitable for assisting total station monitoring, in particular to a controllable light-emitting prism device. Background technique [0002] In surveying work, the use of total stations is not limited to basic survey tasks such as coordinate setting out, and it is also widely used in infrastructure construction such as bridges and tunnels, as well as deformation monitoring of large buildings and structures; the primary use of total stations The condition is that the observation points require a clear view, and its measurement accuracy and efficiency are not only related to the proficiency and work experience of the operator, but also inseparable from the observation environment conditions; especially the total station is used to monitor the settlement of the new tunnel vault and the displacement of the crown beam Or when monitoring the inclination of large buildings or structures in foggy days, due to reasons such...

[0002] In surveying work, the use of total stations is not limited to basic survey tasks such as coordinate setting out, and it is also widely used in infrastructure construction such as bridges and tunnels, as well as deformation monitoring of large buildings and structures; the primary use of total stations The condition is that the observation points require a clear view, and its measurement accuracy and efficiency are not only related to the proficiency and work experience of the operator, but also inseparable from the observation environment conditions; especially the total station is used to monitor the settlement of the new tunnel vault and the displacement of the crown beam Or when monitoring the inclination of large buildings or structures in foggy days, due to reasons such as low tunnel lighting intensity and low visibility in foggy days, the total station spends a lot of time searching for the target prism and aiming at the prism, and it is difficult to aim at the center of the prism. The communication and progress of the measurement progress are greatly affected by the electromagnetic wave signal in the tunnel, which makes the measurement difficult and difficult to guarantee the measurement accuracy, which limits the ranging range of the total station and reduces the measurement efficiency

At present, when measuring under the condition of low visibility, there must be a measuring runner to illuminate the prism of the total station to complete the measurement. can also cause collimation deviation
