Background Outdoor vertical equipment generally comprises a communication base station holding pole, a traffic signal lamp pole, a small weather observation tower, a photovoltaic bracket, a charging pile stand column and the like, and continuously bears multiple environmental effects such as uneven settlement of a foundation, strong wind load, accidental collision, earthquake and ageing of materials in a long-term service process, and the structural stability and the functional reliability of the outdoor vertical equipment are directly related to public safety and operation continuity. Currently, the industry commonly adopts an inclination sensor for posture state monitoring, and the main scheme is single-point arrangement, namely, a high-precision inclination sensor is arranged at a certain position at the middle upper part of equipment, whether overrun is detected by collecting static inclination values in real time, and early warning is triggered after overrun. The method has the advantages of mature technology, low cost and convenient deployment, and forms a certain application foundation in small and medium-sized equipment. However, the single-point posture monitoring scheme has the intrinsic limitations that firstly, the same inclination angle reading is likely to be caused by the integral settlement of a bottom foundation, and is also likely to be caused by top wind load or local collision, inclination causes cannot be distinguished, so that accurate treatment basis is lacked after early warning, secondly, whether equipment is integrally inclined or is subjected to local plastic deformation such as middle buckling, bottom cracking and the like is difficult to distinguish, thirdly, for long and thin vertical equipment, single-point measurement cannot reflect movement differences of different height positions, key instability precursors are easy to miss, fourthly, local vibration interference is remarkable, for example, transient acceleration pulses caused by equipment resonance under high wind or vehicle passing can cause inclination angle data jump, and false alarm is generated.
