In order to avoid overflow of water in the water tank 100, a liquid level sensor 101 is arranged in the water tank 100, the central control system 1 is electrically connected with the liquid level sensor 101, the liquid level sensor 101 is used for detecting the height of a liquid level in the water tank 100 and outputting a liquid level signal to a liquid level comparison module 83 in the central control system 1, a liquid level reference value is preset in the liquid level comparison module 83, and when a received liquid level value is larger than the liquid level reference value of the liquid level comparison module 83, the central control system 1 stops controlling the water supply system 514 to convey water towards the water tank 100.
The implementation principle of the above embodiment is as follows: when a fire disaster occurs rapidly in a fire fighting area, smoke spreads a plurality of fire fighting areas, and an arrow of an escape indication board cannot be seen by an escape person in the fire fighting area, the temperature sensor 222 or the smoke sensor 221 sends the sensed temperature or smoke concentration value to a comparison module in the central control system 1, after comparison, the temperature or smoke concentration value is higher than a preset temperature or smoke concentration reference value, the central control system 1 controls a camera in which the fire fighting area is located to pick up the fire, the camera amplifies and shoots video image data of the position where the fire is dangerous, and sends the recorded fire picture to the display device 4 in real time, and at the moment, the image data of the abnormal position is emphatically displayed on the display screen.
The staff in front of the display screen makes corresponding fire-fighting work according to the fire danger degree, and then the central control system 1 controls the water-spraying fire-fighting component 31 or the dry powder fire-fighting component 32 to be automatically started to extinguish fire in the fire-facing area, meanwhile, the central control system 1 controls the escape door 9 and the water quantity regulating valve 513 to be opened, so that all the spray heads 512 are opened to form a water curtain on the inlet 91 of the escape door 9, in addition, when the central control system 1 controls the escape door 9 to be opened, the indicating screen 6 can be controlled to work, so that the indicating board emits light and illuminates a warning signal, and aiming at the situation, the escape person can be guided to escape from the fire-facing area along the direction of an escape direction arrow.
Meanwhile, the sound signals generated when the spray header 512 sprays are collected, and mixed sound signals of the environment near the spray header 512 are filtered, so that abnormal conditions can be dealt with in time, for example, when the sound generated when the spray header 512 sprays is not collected, preliminary judgment is carried out, a water shortage condition occurs in the water tank 100, and the spray header 512 cannot discharge water, and then the central control system 1 controls the drainage system to discharge water in the water tank 100.
In addition, through the arranged fireproof flame-retardant curtain 521 and the locking part 522, when the water curtain still does not work within a preset time period, the central control system 1 controls the locking part 522, so that the locking part 522 removes the limitation on the fireproof flame-retardant curtain 521, the unlimited fireproof flame-retardant curtain 521 naturally hangs on the inlet opening 91 under the action of gravity, and when the fireproof flame-retardant curtain 521 is unfolded to shield the inlet opening 91, the luminous piece emits light and illuminates the words of 'danger of entering', therefore, the water curtain can be replaced to play a role of isolation, and the entering of escape personnel into a fire area is reduced.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
