NB-IOT technology based elevator intelligent ventilating system

Abstract

The invention provides an NB-IOT technology based elevator intelligent ventilating system. The NB-IOT technology based elevator intelligent ventilating system comprises an environment monitoring module, a micro processor module, a ventilating device and an NB-IOT wireless module, wherein the environment monitoring module comprises a smoke sensor, a smell sensor and a temperature sensor; the smokesensor, the smell sensor, the temperature sensor, the ventilating device and the NB-IOT wireless module are separately connected to the micro processor module; the micro processor module is used for receiving three environment factor data of smoke concentration, air quality and temperature, judging a preset grade which corresponds to each environment factor datum, screening out the environment factor with the highest grade, and controlling the ventilating device to ventilate according to the environment factor with the highest grade; ventilating grade of the ventilating device is equal to thegrade of the environment factor with the highest grade; and the NB-IOT wireless module is used for transmitting the three environment factor data and the ventilating grade of the ventilating device toa monitoring terminal. The NB-IOT technology based elevator intelligent ventilating system has the beneficial effects of regulating gas exchange speed to accurately regulate air quality in the elevator according to environment factor in the elevator.

Description

technical field [0001] The invention relates to the technical field of elevator ventilation, in particular to an elevator intelligent ventilation system based on NB-IOT technology. Background technique [0002] Due to the small space of the elevator, the air quality inside is poor. Especially in hot summer, the temperature in the enclosed space is high, and it is prone to odor and discomfort when there are many people or food is carried. In addition, when a fire breaks out, the elevator stops running, and the ventilation system stops working. If people are trapped in the elevator, the smoke will penetrate into the elevator and cause harm to people. In daily life, most elevators use constant-speed ventilation fans, which cannot adjust the wind speed according to specific environmental requirements, resulting in energy loss or failure to quickly solve problems in harsh air environments. Sometimes when the elevator descends below the ground, the data cannot be transmitted to t...

Problems solved by technology

[0002] Due to the small space of the elevator, the air quality inside is poor, especially in hot summer, the temperature in the confined space is high, and it is prone to odor when there are many people or food is carried, which is likely to cause discomfort

In addition, when a fire breaks out, the elevator stops running and the ventilation system stops working. If people are trapped in the elevator, the smoke will penetrate into the elevator and cause harm to people.

In daily life, most elevators use constant-speed ventilation fans, which cannot adjust the wind speed according to specific environmental requirements, resulting in energy loss or failure to quickly solve problems in harsh air environments.

Sometimes when the elevator descends below the ground, the data cannot be transmitted to the monitoring terminal in time due to poor communication quality
