Further, the controller is internally provided with a timing module; the timing module is electrically connected with the switch of the air pump; the air pump is connected with the helium tank; and an acceleration sensor and a gyroscope are arranged in the monitoring cavity.
Specifically, in this embodiment, since there is a possibility that the gas leaks and decays in the floating ball, it is necessary to supplement the inside of the floating ball at regular time and quantity; helium is preferably adopted to act as the floating gas in the embodiment, the helium balloon is widely used in military and industry, and the durability and the lifting force of the helium balloon are proved to be completely balanced with the gravity of the sliding ring 4.
Meanwhile, because the acceleration sensor is arranged in the monitoring cavity, when the control point base is settled, the displacement rate of the control point base can be perceived, and the data and the settlement length data of the control point are combined, so that the geological environment of the place can be reflected more truly and comprehensively.

When the inclination angle sensing mechanism is adopted, the control point base 1 is inclined, the conductive ball can enter the longitudinal channel or the transverse channel from the horizontal base and is close to a coil arranged in any channel, so that impedance change is caused, and the impedance change amplitude is detected by the impedance sensing sensor. And calculating the inclination angle through the impedance change amplitude according to a preset formula.
When the device works, the air pump and the laser ranging sensor 7 are respectively controlled by a timing module in the controller; specifically, the pump air quantity is preset, so that the lifting force of the floating ball can be balanced with the sliding ring 4, and the sliding ring 4 is positioned in the middle area of the air channel 3; air is supplied at fixed time intervals, so that the lifting force of the floating ball is prevented from being reduced; meanwhile, the timing module sends out signals to the semiconductor laser transmitter in the laser ranging sensor 7 in a fixed time interval, so that the semiconductor laser transmitter transmits laser to the reflecting table, and the refractive laser duration is recovered and analyzed, so that whether the position is changed or not is judged, and a specific numerical value is calculated.
