Whether the residual pressure monitoring system can make our fire safety more secure

With the continuous development of new technologies such as artificial intelligence, big data and 5G, the application of Internet of Things has become a new development. "Smart Fire", "Fire Internet of Things", "Fire Big Data", "Pressure Monitoring System" a series of new fire fighting words come to the fore, what new technology, new technology is it? Can we make our fire safety more secure? ?

When a fire occurs in a high-rise building, the smoke-proof stairwell is a vertical evacuation passage for the inside of the high-rise building. For a smoke-proof stairwell, a fire-fighting elevator front room or a combined front room that does not have natural smoke exhausting conditions, a reasonable mechanical air supply system is provided to prevent the spread of smoke to the stairwell and the front room, and to ensure the smooth evacuation of personnel in the building. Indispensable smoke prevention measures. However, overpressure in the area of ​​the pressurized air supply system is very dangerous. The pressure in the front room or stairwell is too large, and it is difficult or impossible to open the door to open the door, which affects the safety evacuation of personnel.

There are three ways to prevent overpressure: one is to use a residual pressure valve to control overpressure; the other is to set a variable speed fan and pressure sensor; the third is to set a bypass valve and a pressure (difference) sensor. The method of using the residual pressure valve is more conventional and does not require electrical control, so it will not be described again; because JGJ 16 - 2008 "Electrical Design Code for Civil Buildings" 13.6.9 stipulates that "the control circuit of fire-fighting equipment shall not adopt frequency control As a control device, the method of setting the variable speed fan and the pressure sensor cannot be applied in the design; the method of setting the bypass valve and the pressure (difference) sensor is not enough for reference.

In order to ensure that the residual pressure of the evacuation channel can be in an effectively controlled state when the fire occurs, it can prevent the spread of the smoke, and enable the escaper to easily open the fire door to escape, protect the personnel from safe evacuation, and the bird strictly follows the national standard. GB50016-2014 "Code for Fire Protection of Building Design" and "Technical Specifications for Building Smoke Control System", research and development of LNE residual pressure monitoring system.

Le Bird's residual pressure monitoring system is widely used in office buildings, high-rise buildings, shopping malls, hotels, hospitals, residential buildings, etc. Buildings with evacuated walkways can be used.

The application of the residual pressure monitoring system is based on the traditional fire protection, using the Internet of Things technology to network the fire protection facilities, realizing the real-time upload of fire data, so as to achieve the full range of real-time monitoring purposes to ensure fire safety. At the same time, through the characteristics of the fire occurrence, the time summary law, avoiding the high fire fa situation and reducing the fire risk.
