Elevator steel rope fault detection system based on Internet of Things

Abstract

The invention provides an elevator steel rope fault detection system based on the Internet of Things. A central processing unit, a tension sensor, a signal processing circuit, a weighing sensor, a carbon dioxide sensor, an image acquisition module, an image processing module, a drive motor, a wireless sending module, a wireless receiving module, a controller, a big data server, a display module, astorage module, a wireless transmission module and a mobile terminal are utilized for monitoring a pull force signal of a steel rope and image information when an elevator is running, so that the usecondition of the steel rope can be detected, and the steel rope can be timely replaced when being worn; if abnormity is detected under the situation that the elevator falls down suddenly, an emergency circumstance rescue mechanism can be started; and meanwhile, the concentration of carbon dioxide in a lift car of the elevator can be further detected through the carbon dioxide sensor, so that whether a hypoxic condition exists in the lift car of the elevator or not can be known in real time, and the safety of the elevator during the use process is improved.

Description

technical field [0001] The invention relates to the field of intelligent testing, in particular to an elevator steel rope fault detection system based on the Internet of Things. Background technique [0002] According to the requirements of the "Residential Design Code": "Residential elevators must be installed for residential buildings with a height of 7 floors or above or the height of the entrance floor of the household from the outdoor design ground of more than 16 meters." At present, residential buildings with 6 floors and below are residential buildings in my country. The mainstream of construction occupies more than 80% of the construction area. According to national standards, the design of residential corridors should comply with the relevant provisions of the current national standard "Code for Fire Protection Design of Buildings" (GBJ16) and "Code for Fire Protection Design of High-rise Civil Buildings". Elevators required for fire protection; buildings with a he...

Problems solved by technology

[0003] However, while the elevator brings convenience, there are also some hidden dangers. For example, the traction wire rope of the elevator car will wear out after a long time, and may break, and the elevator will suddenly accelerate and fall, etc.
