Background
Along with the rapid development of economy, in cast-in-place concrete construction, the application of a high formwork support system is more and more common, the safety risk is higher and higher, and the high formwork safety accident is mainly caused by the fact that the high formwork generates excessive deformation or excessive displacement under the load action, and the failure of components in the system or the destabilization of the system is induced, so that the high formwork is caused to partially collapse or wholly overturn, and the casualties of construction operators are caused.
The existing high formwork monitoring method is always in the traditional modes of optical observation, manual alarm, theodolite or electronic inclinometer and the like, the measurement error of the theodolite is large, manual observation is needed, and because the observation is blocked by the sight, whether the vertical rod is pressed beyond the bearing range or not due to the fact that the internal formwork of the high formwork is settled or not is often not observed, and the purpose of real-time monitoring is difficult to achieve; the electronic inclinometer is used for monitoring, the acquisition precision of the electronic inclinometer is low, and tiny inclination change information of the vertical rod is difficult to capture; by adopting the optical monitoring instrument, monitoring staff can only monitor outside the supporting system, so that detection staff can only know the peripheral condition of the high formwork and can not sense the internal safety condition of the high formwork, and constructors are difficult to evacuate dangerous areas in time when dangers occur.

Through the high formwork monitoring devices of this patent, though also can produce too big deformation or too big displacement to the high formwork and detect, but the observation route that the camera shot is blocked by the support body easily, leads to detection range limited to the specific pressurized condition of high formwork system internals also can't learn through the camera shooting.
