Radio-controlled switch prism, measurement system composed thereof, and measurement method

Abstract

The invention discloses a prism with the on-off state being controlled wirelessly and electrically. The prism comprises a measurement type prism body. A piece of dimming glass is installed at the front end of the measurement type prism body. The dimming glass is connected with a terminal node. The terminal node comprises a communication module, a control circuit module and a power supply module. The communication module is connected with the input end of the control circuit module and used for receiving remote-control signals. The output end of the control circuit module is connected with the power supply module, and the control circuit module is used for controlling the power supply module according to the content of the remote-control signals. The power supply module is connected with the control circuit module and the dimming glass and is used for supplying power to the dimming glass. According to the prism with the on-off state being controlled wirelessly and electrically, whether the dimming glass is powered on or not is controlled, so that the glass is made to be in the transparent state or in the non-transparent state correspondingly, and then control over the working state of the prism is achieved. Meanwhile, a monitoring sub-system of an automatic total station can effectively organize prism group nodes through a wireless sensor network and control the on-off state of the electrically-controlled prism in cooperation with the automatic total station, and therefore the prism can effectively conduct multi-target identification and search for deformation points.

Description

technical field [0001] The invention relates to the technical field of prism control, in particular to a radio-controlled switch prism, a measurement system and a measurement method composed of the prism. Background technique [0002] With the development of surveying and mapping instruments, the TPS (Total Station Position system) system with electric motor and program control combined with laser communication and CCD technology can realize the automation of measurement, integrating automatic target recognition, automatic sighting, automatic angle measurement and automatic recording. The integrated measurement system, like a robot, continuously and repeatedly observes hundreds of thousands of targets, which can realize the full automation of construction measurement and deformation monitoring. In many large-scale engineering operations, in order to ensure its safety, deformation monitoring is required, and the accuracy requirements are high. [0003] However, due to the re...

Problems solved by technology

[0003] However, due to the relationship between the location of the monitoring point and the location of the setting station, there are often multiple targets in the field of view of the automatic total station, and the instrument cannot correctly identify the problem of measurement errors

[0004] The automatic total station of Sokkia and Leica can detect that there are multiple prisms in the observation area, and the processing strategy is to automatically obtain the measurement data of the nearest prism, but this processing strategy may not necessarily obtain the desired prism in the automatic monitoring process The observation data is not suitable for automatic monitoring; the automatic monitoring software can detect whether the obtained prism measurement data is correct by means of distance or coordinate comparison, but if a wrong measurement occurs, the instrument cannot be controlled to search for the desired prism target; Trimble invented the Source switch prism, add a hood in front of the prism, and use the motor to drive the hood to close up to control the working state of the prism. This technology can solve the problem of multiple prisms in the field of view within a certain range of applications. Due to the large power consumption of the motor drive, a wired Power supply, and the control of the prism also adopts a wired method, which greatly limits the application range of the prism, suitable for outdoor monitoring and long-distance applications
