Problems solved by technology

Because the induction fan cannot identify and judge whether the carbon monoxide exceeds the standard, whether it is caused by a fire or the concentration of automobile exhaust exceeds the standard

Embodiment Construction

[0021] Such as figure 2 As shown, a safe working method for an induced fan system includes the following steps:

[0022] (1) First detect whether there is a fire signal in the environment, if there is a fire signal, control the induction fan to stop and give an audible and visual alarm, if not, enter step (2);

[0023] (2) Check whether the time is up to the scheduled power-on time, if yes, the whole induction fan system will start to work, the working time is set by the user, otherwise go to step (3);

[0024] (3) Check whether the carbon monoxide concentration exceeds the set value. If it does not exceed the set value, the induction fan system will not work. If it exceeds, enter step (4);

[0025] (4) The single machine that detects that the concentration of carbon monoxide exceeds the standard starts to work;

[0026] (5) The working time of the stand-alone machine starting to work is T, which is set by the user;

[0027] (6) Check again whether the concentration of car...

Abstract

The invention discloses a safe working method of an induced fan system. The method comprises the steps that first whether a fire signal exists in an environment or not is detected; if yes, an induced fan is controlled to be stopped and a sound-light alarm is given; if not, whether the preset booting time arrives or not is checked; if yes, the whole induced fan system starts to work, and the working duration is set by a user; otherwise, whether the carbonmonoxide concentration exceeds a set value or not is checked; if not, the induced fan system does not work; if yes, a stand-alone which detects that the carbonmonoxide concentration exceeds the standard starts to work; the work duration of the stand-alone which starts to work is T and set by the user; whether the carbonmonoxide concentration exceeds the set value or not is checked again; if not, the work is stopped; if yes, the whole induced fan system starts to work, and the work duration is set by the user; a linkage exhaust fan and an air supply fan work. The safe working method of the induced fan system has the advantages of safety and reliability in use, real-time detection of whether the carbonmonoxide concentration exceeds the standard or not and corresponding startup and stoppage of the induced fan system.

Description

technical field [0001] The invention mainly relates to the field of induced fan systems, in particular to a safe working method of the induced fan system. Background technique [0002] The induced fan system is a new technology developed in recent years, which is mainly used in the ventilation of underground garages and large areas. Replace the traditional rectangular iron air duct to save floor height and purchase and construction costs. [0003] In order to facilitate the use and management, an intelligent control system has been developed; the control signal has also developed from the initial wired transmission to wireless transmission. With the wide application, more and more attention has been paid to the safety of its use, the scientific rationality of its structure, and the reliability of wireless control technology. [0004] The current induction system according to figure 1 The pattern shown works, with the following disadvantages: [0005] First of all, the un...
