Building fire control linkage method

Abstract

The invention discloses a building fire-fighting linkage method. A plurality of temperature sensors, smoke sensors, cameras, and fire-fighting smoke-exhausting fans are arranged in the building, and an alarm device is arranged in the building. When the temperature sensed by the temperature sensor is greater than or equal to the preset temperature threshold, or the smoke density sensed by the smoke sensor is greater than the preset smoke density threshold, the monitoring personnel will be notified, and the image taken by the camera at the place where the abnormality occurs will be transmitted to the monitoring personnel , so that the monitoring personnel can confirm whether a fire has occurred; if the monitoring personnel confirm that a fire has occurred, the alarm device will be controlled to give an alarm, the fire exhaust fan will be controlled to exhaust the building, the power supply will be switched to the fire protection power supply, and the elevator in the building will be forced to land on the first floor , Start the fire pump. The invention has simple structure, convenient use, greatly saves time, and speeds up the efficiency of evacuation and rescue.

Description

technical field [0001] The invention relates to the field of fire protection, in particular to a linkage method for building fire protection. Background technique [0002] Fire protection work is an important part of national economic and social development, and an indispensable guarantee for the development of a socialist market economy. Firefighting work is directly related to the safety of people's lives and property and social stability. [0003] When New China was first established, our country was in the initial stage of industrialization, and the direct fire losses were correspondingly relatively low. In the 1950s, the direct fire losses averaged about 60 million yuan per year (excluding the data of Hong Kong, Macao and Taiwan, and also excluding underground fires in forests, grasslands, military and mines. The same below). With the development of industrialization and urbanization, fire losses have also increased accordingly: in the 1960s, the average annual direct...

AI Technical Summary

Problems solved by technology

[0005] 1. The elevator does not have anti-high temperature performance. When encountering high temperature, the elevator car is easy to lose control or even deformed and stuck, and some may have the risk of electric shock

[0006] 2. When the elevator is in operation, the elevator shaft will lose its anti-smoke function, resulting in a chimney effect, making it a vertical channel for drawing smoke and helping the fire, which will not only threaten the safety of personnel, but also promote the spread and spread of fireworks

[0007] 3. In the event of a fire, when the electrical lines in the building are burned or the power is cut off, the elevator will stop in the middle of the floor. On the one hand, it is not conducive to the escape of people in the elevator; prone to casualties

[0008] 4. The capacity of the elevator is extremely limited, and usually can only carry a dozen people at a time. When there are many people and concentrated, and the situation is urgent, the evacuation will be slow, which will cause the trapped people to panic and cause confusion, which is easy to squeeze and jump off the building accidents, resulting in undue casualties

[0014] This method only uses the smoke detector to detect the fire. When the smoke detector detects the fire, the alarm device is activated and the 119 fire alarm is directly connected. It is easy to generate false alarms and waste police force.

[0015] In addition, this method does not take into account the need to start the fire pump after a fire, turn on the fire fan to exhaust smoke and make an emergency landing on the elevator
