Description

Internet of things system of construction elevator all-in-one machine

Technical Field

The invention discloses an Internet of things system of a construction elevator all-in-one machine, and particularly relates to the technical field of construction elevators.

Background

Construction elevators (also known as construction elevators) are widely used in the construction industry as the main material transport machinery. Particularly, with the rise of high-rise and super high-rise buildings in recent years, the construction elevator plays an increasingly large role in the modern building construction process, and is continuously developed towards large-scale and intelligentization. However, in the construction process, casualties and equipment damage caused by elevator accidents frequently occur at present, the incidence rate of major accidents is high, and the safety performance of the construction elevator becomes a big problem threatening the lives of construction workers and the properties of enterprises. The reason for the accident of the construction elevator mainly comprises two aspects, namely that on one hand, the operation workers do not know the current state of the elevator, and on the other hand, some operation workers overload the elevator in order to pursue the work efficiency, so that the research on the online real-time monitoring instrument for the running state of the elevator is not slow.

The prior art scheme is that the operation states of equipment including voltage, current, power, weight and the like are detected by a monitoring factory by additionally installing a sensor as an electric control integrated machine part by the frequency converter factory. However, because the agreements of different manufacturers are inconsistent and there is no unified national standard or industry standard, all manufacturers keep their own technical and commercial secrets. Cause many data not have the indirect reading, the sensor collection of installing additional has the deviation again, and monitored control system judges the problem, also can not directly give electrical system and converter and send the instruction, does not have the non-and intervenes.
