Intelligent fresh air system integrated with safety alarm control and control method thereof

Abstract

The invention discloses an intelligent fresh air system integrated with safety alarm control and a control method thereof. The system comprises a fresh air intake module and a negative pressure exhaust module, and further comprises a gas leak detection module, a natural gas pipeline switch module, a power supply module and a controller. The fresh air intake module, the negative pressure exhaust module, the gas leak detection module and the natural gas pipeline switch module are separately connected with the controller, and the fresh air intake module, the negative pressure exhaust module, thegas leak detection module and the natural gas pipeline switch module are separately connected with the power supply module. The fresh air intake module and the negative pressure exhaust module separately include an explosion-proof fan and a metal pipeline, fire proof plates are applied outside the metal pipeline, and a motor used in the explosion-proof fan includes at least two rotational speeds.The danger of gas leakage can be effectively detected through the intelligent fresh air system integrated with safety alarm control and the control method thereof, and gas is safely, efficiently and quickly discharged to the outdoor.

Description

technical field [0001] The invention relates to the technical field of fresh air and emergency alarm and processing systems used in buildings, in particular to an intelligent fresh air system with integrated safety alarm control and a control method thereof. Background technique [0002] The fresh air system is a set of air treatment system composed of an air supply device and an exhaust device. The outdoor air is purified by the fresh fan and introduced into the room, and the indoor air is exhausted by the negative pressure fan. A "fresh air flow field" will be formed indoors to meet the indoor The need for fresh air. Although the current fresh air system can enjoy fresh air without opening windows; effectively discharge various bacteria and viruses in the room; reduce indoor carbon dioxide concentration and other functions. [0003] In the existing technology, the technology of fresh air system for dealing with dangerous situations such as natural gas leakage is not yet m...

Problems solved by technology

[0003] In the existing technology, the technology of fresh air system for dealing with dangerous situations such as natural gas leakage is not yet mature. For example, the patent application with the patent number "2017203823777" and the patent name "An Intelligent Security Alarm System" discloses the use of fresh air to replace The gas machine handles the problem of indoor gas leakage, but there is no public explanation on how to deal with it. Patent applications with patent numbers "2017111004476", "2017114698370", and "US20020183001A1" all disclose the use of fresh air systems or air exchange systems to discharge indoor gas or other harmful gas solutions, but all have the defects of low treatment efficiency and untimely exhaust
