(two) background technology:

In the automatic fire alarm system, the device used to send out fire alarm signals that are different from ambient sound and light is called a fire alarm device. A fire alarm signal is issued in the area to warn people to take safe evacuation, fire fighting and disaster relief measures. It is an automatic fire-fighting facility installed in buildings or other places in order to detect and report fires early, and take effective measures in time to control and extinguish fires. It is one of the indispensable safety technical facilities for modern firefighting. The traditional fire alarm and sprinkler systems are generally installed independently in the building, and there is no close connection between them, and there is no linkage fire alarm network with the upper fire control mechanism. When the existing system is installed in a large-scale logistics storage site, once a fire breaks out, it is difficult for the fire control room to act quickly, resulting in increased losses.

(3) Contents of the invention:

The working process of the present utility model is:

(1) When a large amount of smoke is generated in the smoldering stage of the initial fire, the smoke alarm system in the grass-roots storage control point sends out a fire alarm signal, and at the same time, the upper alarm display fire control room obtains the incident information from the video surveillance network system. The general monitoring station of the Public Security Fire Bureau sends out an alarm signal through the telephone communication system, and on the one hand activates the automatic sprinkler system of the fire alarm controller in the storage control point at the grassroots level;

(2) The fire alarm controller in the grass-roots storage control point controls the air compressor. When the air pressure drops to the lowest level, it will automatically start the air compressor. When the specified pressure is reached, the air compressor will be shut down and the fire alarm controller will be activated simultaneously. Pre-action alarm valve group;

(3) The pre-action alarm valve group in the fire alarm controller starts the spray water pump through the pressure sensor, and at the same time the fire alarm controller starts the electric valve in the spray system, opens the quick exhaust valve, and acts on the water storage equipment connected sprinkler pumps;

(4) The spray water pump sprays and supplies water to the fire scene, and connects the water flow indicator at the same time, and feeds back to the fire alarm controller.

The working principle of the utility model: the system installs a level-by-level monitoring system in the logistics storage site, so that the fire information can be discovered in time, and dealt with in time to avoid major disasters. Among them, the fire alarm controller controls the smoke alarm system and sprinkler system, and the fire alarm controller in the grass-roots storage control point forms a linkage system with the upper fire alarm system, which realizes the effective prevention of the fire scene. The first step in this prevention is the smoke detector in the fire alarm controller, which is used to monitor the concentration of smoke in the storage site at any time. The working principle of the smoke detector is that there is a radioactive source americium 241 in the inner and outer ionization chambers, and the positive and negative ions generated by ionization move to the positive and negative electrodes respectively under the action of the electric field. Under normal circumstances, the current and voltage of the inner and outer ionization chambers are stable. Once smoke reaches the outer ionization chamber and interferes with the normal movement of charged particles, the current and voltage will change, destroying the gap between the inner and outer ionization chambers. Therefore, the wireless transmitter sends out a wireless alarm signal, notifies the remote receiving host, transmits the alarm information to the fire alarm controller and at the same time shows the location of the fire according to the video surveillance network system, and records the location and time of the fire ;After the fire alarm controller receives the signal, it will send the signal to the pre-action alarm valve group. The pre-action alarm valve group system is usually filled with pressure water in the pipe network. If a fire occurs in the protected area, the temperature at the nozzle will rise, and the glass ball will break. When one or more nozzles spray water, the water starts to flow in the wet system, the pressure in the pipe network decreases, the valve group is opened to allow the water to flow continuously to the wet water area, and the hydraulic alarm bell and pressure switch are activated at the same time; in the fire alarm controller When it is set to the automatic state, the pressure switch will automatically start the sprinkler pump in the pump room when it receives a signal, and the water pump will supply water to the pipe network to automatically extinguish the fire; the automatic fire alarm system is also connected with the air compressor, and the air The press makes the automatic sprinkler pipe in the fire alarm controller be filled with compressed air, and the front end of the quick exhaust valve of the pressurized gas pipeline is equipped with an electric valve, which is opened at the same time as the sprinkler pump is started; the automatic fire alarm system sends out an alarm signal After the sprinkler pump is started, the automatic sprinkler system sends a signal to the control panel controlling the deluge valve through the fire alarm controller to start the deluge valve linkage, and the corresponding pressure switch is closed after spraying water, and finally the signal is sent back to the fire alarm system , thus forming a complete set of automatic fire alarm and sprinkler system.

The utility model has the advantage that: the fire-fighting smoke alarm and automatic sprinkler system used in the logistics storage site involved in this case can monitor the fire-fighting conditions of the logistics storage site with a large area, such as in the automatic cotton storage warehouse of ^6000m2 It can install more than 800 automatic sprinkler devices, dozens of fire automatic smoke alarm systems, establish a network fire alarm point, and combine with the entire bonded area fire alarm system to form a linkage system. Once a fire occurs, it can quickly and effectively take rescue actions .
