Abstract

The invention provides a remote control folding prism device. The device comprises a plurality of refractive prism holders and a remote control terminal, the plurality of refractive prism holders arelinearly arranged and arranged at equal height; each of the refractive prism holders comprises a local controller, a refractive prism, a drive module, a location detection module, a local wireless transmission module and a local power supply module, the local controller is in signal connection with the drive module, the location detection module and the local wireless transmission module, the local power supply module is respectively and electrically connected with the local controller, the drive module, the location detection module and the local wireless transmission module; the drive moduleis also connected with the refractive prism; and the local wireless transmission module is in signal connection with the remote control terminal. The device can realize remote control of the refractive prism through the remote control terminal, no operator is required to adjust the folding prism posture on site; communication between the refractive prism holders and the remote control terminal isbased on a LoRa wireless transmission module, formation cost is low, signals are high in quality and can completely cover a whole long baseline site.

Description

technical field

[0001] The invention relates to the field of measuring instrument detection, in particular to a remote-controlled folding prism device. Background technique

[0002] According to the existing metrology regulations, the verification of the total station needs to be carried out on the longer baseline field. On the ground greater than 1000 meters above the longer baseline field, a plurality of observation piers with different distances are set up in the same straight line and numbered sequentially. The number of piers should be no less than 7, and the distances between them can be combined into at least 21 standard distances after calibration. During the verification, the total station should be placed on one observation pier, and refracting prisms should be placed on the rest of the observation pier. Use the total station to collimate the prism for measurement, and obtain multiple observation values. By comparing the observation values ​​with the standard dista...
