Specifically, when a fire disaster occurs in a field to be protected, a person on duty may observe the fire disaster, but the intelligent monitoring device does not detect the fire disaster due to sensitivity or line fault, at the moment, the person on duty can input an alarm manual to the intelligent manual device, and after the intelligent manual receives the alarm manual input by the person on duty, the manual information and second alarm information are sent to the cloud platform.
In some implementation modes, the intelligent manual reporting device can be a simple alarm button device with a built-in positioning module, the manual reporting information is positioning information of the intelligent manual reporting device, and when a person on duty observes a fire, the intelligent manual reporting device can directly send a second alarm signal and positioning information of the fire occurrence position to the cloud platform.
In other implementations, the intelligent manual reporting device may have input conditions, such as a keyboard, a handwriting pen, a handwriting screen, and the like, and when the attendant observes that a fire occurs, the attendant may input information related to the fire, such as an object of the fire, a cause of the fire, and the like, to the intelligent manual reporting device, where the information is manual reporting information, and thus the intelligent manual reporting device may directly send the second alarm signal and the information to the cloud platform.
The cloud platform is used for receiving and storing the monitoring information, the hand-reporting information, a first alarm signal and a second alarm signal, sending the first alarm signal and/or the second alarm signal to the alarm device when receiving the first alarm signal and/or the second alarm signal, and sending a fire extinguishing signal to the fire extinguishing device.
Specifically, after receiving the monitoring information, the hand-reporting information, the first alarm signal and the second alarm signal, the cloud platform stores the information, so as to provide data support for analyzing the fire cause or the development process, and when receiving any one of the first alarm signal and the second alarm signal or simultaneously receiving the first alarm signal and the second alarm signal, the cloud platform sends the received first alarm signal and/or the second alarm signal to the alarm device and sends the fire extinguishing signal to the fire extinguishing device.
The alarm device is used for starting alarm when receiving the first alarm signal and/or the second alarm signal.
Specifically, when the alarm device receives a first alarm signal and/or a second alarm signal sent by the cloud platform, the alarm device starts to alarm to prompt an on-duty person that a fire disaster occurs in a field to be protected.
In some specific implementation modes, the alarm device can be an intelligent broadcasting device, and when the intelligent broadcasting device receives the first alarm signal and/or the second alarm signal, voice broadcasting can be carried out to explain the fire and prompt related personnel to evacuate orderly;
in other specific implementation manners, the alarm device can be an audible and visual alarm, and when the audible and visual alarm receives the first alarm signal and/or the second alarm signal, the audible and visual alarm can start alarming and lighting to prompt related personnel of occurrence of a fire and prompt people of evacuation as soon as possible.
The fire extinguishing device is used for receiving fire extinguishing signals and extinguishing fire.
Specifically, the fire extinguishing device extinguishes the fire after receiving the fire extinguishing signal sent by the cloud platform.
In some implementations, a fire extinguishing agent storage module can be disposed in the fire extinguishing apparatus, and when a fire occurs, the fire extinguishing apparatus opens the fire extinguishing agent storage module to extinguish the fire.
According to the intelligent alarm system, the intelligent manual alarm device and the intelligent monitoring device are linked, the cloud platform and the alarm device are combined, a to-be-protected field is monitored and protected from two angles of manual alarm and automatic alarm, when the cloud platform receives any one of the first alarm signal and the second alarm signal, the alarm device can give an alarm, the sensitivity of monitoring alarm is improved when a fire disaster occurs, and therefore early warning can be carried out on the fire disaster in the early stage of the fire disaster; meanwhile, the fire extinguishing device is combined to automatically extinguish the fire of the site to be protected, so that the development of fire can be effectively controlled, and the influence caused by the fire is reduced.
In some embodiments, the intelligent monitoring device comprises: an intelligent fire monitoring module; the intelligent fire monitoring module comprises: a smoke sensor, a light sensor and a temperature sensor; the intelligent fire monitoring module is used for monitoring the smoke concentration, the light intensity and the temperature of the site to be protected in real time, and sending a first alarm signal to the cloud platform when any one of the smoke concentration, the light intensity and the temperature is abnormal.
Specifically, the intelligent monitoring device is arranged in a to-be-protected field, and an intelligent fire monitoring module can be arranged in the intelligent monitoring device to monitor the environmental index of the to-be-protected field in real time. When the conflagration appears in treating the protection place, the smog concentration, the temperature and the light intensity in treating the protection place can appear obviously changing mostly, consequently, smog concentration, temperature and the light intensity in treating the protection place can be monitored through smoke transducer, light sensor and temperature sensor to intelligence fire monitoring module to when any one environmental index of smog concentration, temperature and light intensity appears unusually, send first alarm signal to the cloud platform.
Through intelligent fire monitoring module, can monitor at any time and treat whether normal the smog concentration, light intensity and the temperature in protection place, in case any one of them environmental index has unusually can in time report to the police to the cloud platform to in time discover the conflagration, reduce the influence that the conflagration caused.
In other embodiments, the intelligent monitoring apparatus comprises: a video monitoring module; the video monitoring module is used for collecting the video information of the to-be-protected field, carrying out video analysis on the video information, identifying whether flame or smoke exists in the to-be-protected field, and sending a first alarm signal to the cloud platform when identifying that flame or smoke exists in the to-be-protected field.
Specifically, when a fire disaster occurs, special elements such as smoke, flame and the like can appear, and therefore a video monitoring module can be arranged in the intelligent monitoring device and used for collecting video information of a site to be protected and analyzing the video information. When a fire disaster occurs in the to-be-protected field, the video monitoring module can identify whether flame or smoke exists in the to-be-protected field in the video information, and if the flame or smoke exists in the to-be-protected field, a first alarm signal is sent to the cloud platform.
