The internal functions of high-rise buildings are generally more complicated, and there are many electrical equipments. There are a lot of fire hazards. If the management is not good, it is easy to cause fires. In particular, some high-rise public buildings with large construction areas and large number of floors are more complicated, and once a fire occurs, serious consequences will result. In recent years, high-rise building fire accidents have shown a clear upward trend, and group deaths and injuries have occurred, causing great losses to the country and people's lives and property. According to the analysis of the number of fire deaths in the fire statistics, 78.9% of the total number of fire deaths were caused by smoke; the majority of the people killed by fire were suffocated by smoke and poisoned. Can not be safely evacuated. It is necessary to know that the stairwell and its front room or the combined front room are places for temporary evacuation and evacuation of fire personnel. The fire elevator room and its front room are the main passages for firefighters to enter the high-rise building to extinguish fires. In order to prevent the smoke from entering these parts or exhausting the smoke from these parts, the personnel are safely evacuated and saved. Therefore, the super high-rise building is equipped with a residual pressure monitoring and control system in the above-mentioned parts, which can achieve the purpose of smoke-free on the evacuation and rescue channels. At the same time, the residual pressure monitoring and control system air supply facilities are installed in the closed refuge layer of the super high-rise building, in addition to satisfying the certain residual pressure value in the refuge layer, preventing the smoke from invading, and also providing fresh air for breathing in the refuge floor. . The residual pressure monitoring system is an intelligent system integrating industrial computer, communication, anti-electromagnetic interference, digital sensing technology and fire two bus. High-sensitivity pressure sensor, 24-hour real-time automatic inspection and collection of monitoring area or pressure change and other working conditions, alarm signals for overpressure and other faults are recorded. When the residual value of the anti-smoke stairwell or the front room reaches the overpressure monitoring value, the Lebe residual pressure detector sends an alarm signal, and the Lebe residual pressure controller opens the bypass pressure relief valve on the air duct of the pressurized fan, and the residual pressure falls back to After the normal value, the residual pressure detector sends a signal, and the residual pressure controller closes the bypass valve to keep the residual pressure value stable within the specification requirement interval by controlling the opening of the bypass valve. The system has real-time, numerical, intelligent Characteristics of continuous and automated monitoring. In the context of the Internet + era, it is necessary to create an ecological circle and comprehensively consider the concerns of all parties. Therefore, the residual pressure monitoring system is more than just a technical solution that requires innovation in the construction, operation and commercialization of fire safety services. The “ Residual Pressure Monitoring System †provides a new way of thinking and a new path for solving the current bottleneck problem of building fire safety. The use of big data, Internet of Things and other technologies to build a residual pressure monitoring system, effectively integrate the forces of all parties, find out the base of fire, accelerate the construction of urban public safety, fire prevention and control system, become the key to master the fire, disaster relief initiative, but also To ensure a safe protection for the firefighters' own safety!
