Description

Damper control device and method based on limit sensor {APPARATUS AND METHOD FOR CONTROLING DAMPER BASED ON LIMIT SENSOR}

This application relates to a limit sensor-based damper control device and method.

According to the fire safety standards currently applied in Korea, the wind speed that can effectively prevent the inflow of smoke from indoors into the smoke control area is defined as smoke retardant wind speed, and is specifically set to be 0.5 m/s or more or 0.7 m/s or more. The flame retardant wind speed value is being determined.

However, if the opening area of the automobile pressure damper, which is usually placed in the smoke control area, is applied as specified by the Korea Fire Industry & Technology Institute, the smoke prevention wind speed is close to the predefined smoke prevention wind speed value depending on the size of the fire door, etc. (for example, It may be formed at a value around 0.7 m/s, etc.), but it may also be formed at a level that significantly exceeds the set appropriate smoke control wind speed value, such as a smoke control wind speed of 3 m/s.

In this regard, the higher the smoke prevention wind speed, the greater the amount of wind input into the smoke prevention area, which has the advantage of dramatically preventing the inflow of smoke when the door between the smoke prevention area and the interior is opened. However, due to the strong wind speed, the inflow of smoke is more dramatically prevented. On the contrary, there is a risk that the fire may intensify further.

This may mean that the sensor 112 is disposed.

In this regard, as the limit sensors 111 and 112 are disposed in positions capable of detecting the operating position of the rack-and-pinion structure 230, a threshold level corresponding to a preset threshold is determined according to the driving of the damper mechanism 200. When the rack-and-pinion structure 230 moves to be close to the limit sensors 111 and 112 whose positions have been adjusted, the damper control device 100 adjusts the degree of opening to a degree that meets the preset threshold level. It is determined that the damper mechanism 200 can perform control to limit the behavior of the damper mechanism 200 so that the opening degree (opening ratio) of the damper 10 does not increase any further.

The threshold level is set so that the smoke-reducing wind speed formed in the target space where the damper is installed is within a preset range,
The threshold level is a comparison of analysis data on a pattern in which the smoke-proof wind speed of the target space changes according to a change in the position of the limit sensor and actual data on the smoke-proof wind speed measured by the limit sensor placed at a predetermined test location. It is set according to the results,
When the actual measurement data is acquired in a pattern that matches the analysis data, the threshold level is set by applying the correlation between the location information of the limit sensor corresponding to the analysis data and the smoke prevention wind speed,
When the measured data is obtained with a pattern that does not match the analysis data, the threshold level is calculated by applying a predetermined transformation to the correlation. According to paragraph 1,
