Fire is one of the most common disasters that endanger the safety of the public. Especially in the storage room, archives, containers, long-distance truck cars, and other closed spaces, once there is a combustion accident, it is usually difficult to find it for the first time. Only when the fire spreads seriously, then it can be noticed and then put out. In this way, it is easy to delay the best time to put out the fire and even cause serious dangerous accidents such as the explosion in the later stage of the fire, resulting in inestimable personal safety hazards and economic property losses. At present, the fire extinguishing devices in the market need to be turned on manually, and only when the flame burning site is accurately found, then the fire can be extinguished effectively. And in chemical warehouses and other more dangerous places, the use of a manual fire-fighting set is also very unsafe. Therefore, a device that can automatically detect the fire and extinguish the explosion is especially needed in the place where the fire occurs frequently. That’s the automatic fire suppression system.
The automatic fire suppression system can detect the position of the fire source at the beginning of the fire and put out the fire and explosion suppression in time. automatic fire suppression system includes fire extinguishers, probes, and controllers. The detector is electrically connected to the controller to detect the combustion flame and send the flame signal to the controller. The controller is electrically connected to the fire extinguisher and is used to receive the flame signal sent by the detector and send the start signal to the fire extinguisher. After the fire extinguisher starts, the combustion flame can be extinguished in time, and the effect of automatic fire extinguishing and explosion suppression can be achieved without manual participation. Both the detector and the fire extinguisher are multiple, and they are a one-to-one correspondence. In this way, the controller can judge the position of the fire source according to the signal source of the detector, start the fire extinguisher at the corresponding position, and realize the accurate fire extinguishing. The controller includes a power supply module, a control module, and a display module. The power supply module supplies power to the control module and the display module. The control module judges the combustion position according to the signal sent by the detector and sends the starting signal to the fire extinguisher corresponding to the detector. The display module is used to display the working status and power status of each fire extinguisher. The controller also includes a detection module for detecting the working state of the input and output channels of the signal and sending the working state to the monitoring center to prevent the failure of the automatic fire extinguishing and explosion suppression device caused by the failure of the communication system. The controller also includes a manual automatic switching switch for manually controlling the fire extinguisher to be turned on, which can be manually controlled in the event of a failure of the detector or communication system. The detector is read ultraviolet composite flame detector with high sensitivity, short reaction time and low false alarm rate. The fire extinguisher is hexafluorohydrin fire extinguisher, which has the features of reliable performance, environmental protection, and high efficiency.
