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.
