Control method for indoor fire alarm

Abstract

The invention relates to a control method for indoor fire alarm, in particular to a control method capable of detecting indoor environmental humiture, reducing temperature and increasing humidity. The method comprises the following steps: utilizing a sensor to sense the humiture change of the indoor environment; starting a sprayer (non-fixed point type) to spray fine water mist when the indoor temperature is increased and the humidity is decreased; reducing the temperature and increasing the humidity by attaching the water mist to the indoor articles, and using the sensor to continuously sense if the indoor temperature is reduced and the humidity is increased or not; if the indoor temperature is reduced and the humidity is increased, turning off the sprayer; if the indoor temperature is increased and the humidity is decreased, restarting the sprayer for spraying the water mist and starting an automatic temperature-sensing water sprayer at proper time for spraying the water mist to a specific position and area (fixed point type); and then turning off the automatic temperature-sensing water sprayer till the sensor detects that the indoor temperature is reduced and the humidity is increased, thereby relieving the indoor fire alarm, achieving the purposes of controlling the indoor fire alarm, spraying water mist in sections and reducing the loss of the indoor articles caused by water, and reducing the degree of casualty loss.

Description

technical field [0001] The present invention provides a control method for indoor fire alarms, especially a control method that can detect changes in the temperature and humidity of the indoor environment, and perform cooling and humidification. Reduce the degree of damage to indoor items. Background technique [0002] By the way, in most buildings, in order to prevent accidental disasters such as fire and theft, safety detection and alarm devices will be installed for safe maintenance to reduce losses caused by accidental disasters; and fire prevention , is the use of smoke sensors, temperature and humidity sensors, etc., to detect changes in temperature and humidity of the indoor environment, in order to sprinkle water to cool down and increase humidity, so that the occurrence of fire accidents can be timely resolved. Generally, indoor fire accidents occur, most of which are If it is caused by electric wire fire, kitchen fire or indoor fire such as cigarette butts, igniti...

Problems solved by technology

[0003] (1) Once the indoor sprinkler is turned on, it will spray a large amount of water. Although it can eliminate the smoke and fire sources, it will also cause serious water damage to indoor items, such as electronic and electrical products being soaked in water, causing internal circuit damage, If it can no longer be used, the furniture will be damaged by the impact of the water column, and the indoor springs will also be seriously damaged, that is, they must all be replaced with new ones, which will also increase the loss of money.

[0004] (2) If there is only a local smoke or fire source in the room, once the sensor detects changes in smoke or temperature and humidity, it will start the sprinklers around the accident site to sprinkle water, and it will also cause other fires far away from the fire source. If the indoor items are also damaged innocently, the degree of damage to the items cannot be reduced, resulting in serious indoor damage and failure of all items, the impact is quite serious, and it will take a long time to restore the indoor state

[0005] (3) If gas spraying equipment and powder spraying equipment are installed in the room, it is to spray compressed air through the spray head into the room or to spray the items in the room with powder, although it can reduce the water damage to the indoor items, but the gas or powder After spraying, there will be no gas or powder, which can be sprayed again. If the smoke or fire source re-ignites, the gas or powder cannot be sprayed again, and the fire situation cannot be completely eliminated, and there is still a high risk

[0006] Therefore, how to solve the known problems of fire prevention, water damage, and damage in the interior of buildings, resulting in the shortcomings that all interior items and decorations must be updated, is what the relevant manufacturers engaged in this industry are eager to study and improve. direction
