3results about How to "Automate Calibration" patented technology

This utility model discloses a horizontal monitoring device for building construction, including a stabilizing frame with adjustable support legs at its lower end. A monitoring component for horizontal monitoring is installed inside the stabilizing frame, and a counterweight is installed at the lower end of the monitoring component. The monitoring component includes a connecting pipe. In this utility model, by setting up the monitoring component and using the connecting pipe in conjunction with magnetorheological fluid, the monitoring component can be leveled by its own counterweight in a natural state. Then, by controlling the operation of the electrodes, the magnetorheological fluid is solidified, ensuring that the laser emitting component remains horizontal. In this state, the laser emitting component emits laser lines, which, in conjunction with the construction workers' operations, achieve the purpose of horizontal monitoring. Simultaneously, a wireless control module can be used during construction to remotely control the operation or stop of the electrodes, achieving automated calibration without the need for repeated adjustments by the user.
