The present invention proposes a holographic intelligent perception and early warning system for the operation status of a concrete pole. The holographic intelligent perception and early warning system comprises a data acquisition module. The data acquisition module establishes a data acquisition link through cables with an anemometer and anemometer arranged on the top of the pole, an inclination sensor of the pole, a rebar gauge and a concrete surface strain gauge and a temperature sensor arranged on the pole body, and an earth pressure box sensor and a temperature and humidity sensor arranged at the pole foundation. The present invention tailors a set of holographic intelligent perception and early warning systems for the operation status of the concrete pole. By monitoring various key parameters of the pole, the operation status of the pole can be fully and comprehensively grasped in real time, and danger can be warned.

The embodiment of the invention provides an air conditioner control method and system, electronic equipment and a storage medium, and the method comprises the steps that communication with a detection device is established, and the detection device is powered by mains supply; determining whether a mains supply outage condition is met or not according to a communication signal with the detection device; and after the mains supply outage condition is met, the air conditioner is switched to a backup power supply mode from the mains supply power supply mode, and the air conditioner is switched to a second working mode from a formal first mode. The standby power supply can be automatically switched to supply power to the air conditioner after the mains supply is powered off, normal work of the air conditioner under the power failure condition is guaranteed, air conditioner shutdown or damage caused by power interruption is avoided, air conditioner power consumption is reduced after the standby power supply is switched to supply power to the air conditioner, and air conditioner power consumption can be reduced when power consumption of the standby power supply is insufficient. Therefore, the power supply power of the back-up power supply is reduced, and the situation that the back-up power supply is unstable in power supply due to overlarge power supply power of the back-up power supply is reduced.
