Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a rescue assistance apparatus 10 including: a controller 101 connected to the fire detector 20, and a life detector 102 and a wireless communication module 103 connected to the controller 101;
the life detector 102 is used for detecting the vital sign information of people in a detection area corresponding to the installation position of the fire detector 20 in real time and sending the detected vital sign information to the controller 101;
the controller 101 is configured to send installation location information of the fire detector 30 to at least one rescue terminal 30 through the wireless communication module 103 in a wireless communication manner when receiving fire alarm information from the fire detector 20 and determining that a person is in a detection area according to the vital sign information sent by the life detector 102.
According to the rescue auxiliary device provided by the embodiment of the invention, the life detector can detect the vital sign information of people in the detection area near the fire detector in real time and send the acquired vital sign information to the controller, when the fire detector detects that a fire occurs and sends fire alarm information to the controller, the controller can determine whether a person is in a detection area near the fire detector according to the vital sign information sent by the life detector, the controller may transmit installation location information of the fire detector to the at least one rescue terminal through the wireless communication module after determining that someone is in the detection area, so that the rescuers can determine the area where the trapped people are located through the installation position information of the fire detector displayed by the rescue terminal, and then can search for and rescue stranded personnel fast to can improve the efficiency of rescuing stranded personnel in the conflagration.
Alternatively, on the basis of the rescue assisting apparatus 10 shown in fig. 1, after receiving the fire alarm information from the fire detector 20, the controller 101 may determine whether there is a person in the detection area at the current time according to the received vital sign information, and may also determine whether there is a person in the detection area within a recent period of time according to the previously received vital sign information, so as to determine whether there is a person in an area adjacent to the detection area after the fire occurs. Specifically, the controller 101 transmits installation position information of the fire detector 20 to at least one rescue terminal 30 in a wireless communication manner through the wireless communication module 103 when receiving fire alarm information from the fire detector 20 and determining that a person is in a detection area within a preset time period elapsed from the reception of the fire alarm information from the vital sign information transmitted from the life detector 102.
For the same fire detector, a detection area corresponding to the installation position thereof is a relatively fixed area, and people can move, so that people may enter an area adjacent to the detection area through the detection area in a period before the fire occurs, and the fire is trapped in the area adjacent to the detection area after the fire occurs. After receiving the fire alarm information, the controller 101 determines whether people are in the detection area within a recent period of time according to the received vital sign information, and then determines whether people are trapped in the area within a certain distance range from the installation position of the fire detector 20, so that the installation position information of the fire detector 20 is sent through the wireless communication module 103 after people are in the detection area within a recent period of time, and the rescue personnel is informed that people are in the area near the installation position of the fire detector 30, and the efficiency of rescuing the trapped people in the fire is further improved.
For example, after receiving the fire alarm information, the controller 101 determines whether a person is in the detection area within the past 1 minute according to the vital sign information received within the past 1 minute, if so, it indicates that a person is trapped in an area that is not more than 1 minute away from the detection area after the fire occurs, and then the controller 101 sends the installation position information of the fire detector 20 to the rescue terminal 30 by using the wireless communication module 103.
Optionally, on the basis of the rescue assisting apparatus 10 shown in fig. 1, as shown in fig. 2, the rescue assisting apparatus 10 may further include an Uninterruptible Power Supply (UPS) 104, where the UPS 104 is configured to supply Power to the fire detector 20, the controller 101, the life detector 102, and the wireless communication module 103 after the connected external Power supply stops inputting Power.
When a fire disaster occurs in a building, a power supply in the building is usually required to be cut off, and in order to ensure that a fire detector, a controller, a life detector and a wireless communication module can normally work after the power supply is cut off, the fire detector, the controller, the life detector and the wireless communication module are supplied with power through an uninterrupted power supply. When the external power supply normally inputs electric energy to the uninterruptible power supply, the uninterruptible power supply supplies power to the fire detector, the controller, the life detector and the wireless communication module by using the electric energy input by the external power supply, and when the external power supply stops inputting the electric energy to the uninterruptible power supply, the uninterruptible power supply supplies power to the fire detector, the controller, the life detector and the wireless communication module by using the electric energy stored in the storage battery, so that the fire detector, the controller, the life detector and the wireless communication module can continue to work normally for a period of time after the external power supply is cut off.
Set up uninterrupted power source in rescue auxiliary device, utilize uninterrupted power source for fire detector, a controller, life detector and wireless communication module power supply, guarantee that fire detector after the conflagration takes place, a controller, life detector and wireless communication module can normally work, if the regional someone near fire detector in the recent period of time that the conflagration takes place, can send fire detector's mounted position information for at least one rescue terminal, the information that rescue personnel can show through rescue terminal confirms that there is stranded personnel to be located near this fire detector, in time, rescue the stranded personnel effectively. Therefore, through set up uninterrupted power source in the rescue auxiliary device to supply power for fire detector, controller, life detector and wireless communication module through uninterrupted power source, guarantee that rescue auxiliary device can provide the regional relevant information in stranded personnel place reliably after the conflagration takes place.
It should be noted that the input end of the uninterruptible power supply is connected with an external power supply, the output end of the uninterruptible power supply is respectively connected with the power input ends of the controller and the fire detector, so that the controller and the fire detector are powered by the uninterruptible power supply, and the life detector, the wireless communication module and the like connected with the controller can obtain electric energy supplied by the uninterruptible power supply from the controller.
Optionally, on the basis of the rescue aid 10 shown in fig. 2, as shown in fig. 3, the rescue aid 10 may further include a voltage monitor 105;
the voltage monitor 105 is configured to send power-off alarm information to the controller 105 when it is monitored that the external power supply stops inputting electric energy to the uninterruptible power supply 104;
when receiving the power-off alarm information from the voltage monitor 105 and determining that a person is in the detection area according to the vital sign information sent by the life detector 102, the controller 101 sends the installation position information of the fire detector 20 to at least one rescue terminal 30 through the wireless communication module 103 in a wireless communication mode.
In addition to stopping the power supply from the external power supply to the uninterruptible power supply when a fire occurs, the external power supply also stops supplying power to the uninterruptible power supply due to damage of a power supply cable when a catastrophic accident such as an earthquake or an explosion occurs, and people are trapped in a building and need to be rescued due to the catastrophic accident such as the earthquake or the explosion, so whether the external power supply stops supplying power to the uninterruptible power supply or not can be used as another trigger signal for triggering the installation position information of the fire detector to be sent to the rescue terminal.
The voltage monitor monitors whether the external power supply stops inputting electric energy to the uninterruptible power supply in real time, and when the external power supply stops inputting electric energy to the uninterruptible power supply, the voltage monitor sends power-off alarm information to the controller. After the controller receives power-off alarm information from the voltage monitor, the controller determines whether people are in the area near the fire detector at the current time according to the vital sign information sent by the life detector, if the people are determined to be in the area near the fire detector at the current time, the situation that people are trapped in the area near the fire detector is shown, and the controller sends installation position information of the fire detector to at least one rescue terminal in a wireless communication mode through the wireless communication module. After the rescue terminal receives the installation position information of the fire detector from the wireless communication module, the rescue terminal can display the installation position information of the fire detector, and rescuers can find trapped people trapped in the area near the fire detector as soon as possible according to the information displayed by the rescue terminal, so that the efficiency of rescuing the trapped people in disasters such as earthquakes, explosions and the like is realized.
The voltage monitor is arranged in the rescue auxiliary device, and the voltage monitor monitors whether the external power supply stops inputting electric energy to the uninterruptible power supply or not, so that the electric energy is used as a trigger signal for disasters such as earthquake, explosion and the like, and therefore, after disasters such as earthquake, explosion and the like occur, rescuers can know the area where the trapped person is located, and the trapped person can be rescued in time. Therefore, the rescue auxiliary device can improve the efficiency of rescuing the trapped people in the fire, and can also improve the efficiency of rescuing the trapped people in the disasters of power failure caused by earthquakes, explosions and the like.
In the embodiment of the invention, the voltage monitor can be connected to a power supply cable between the external power supply and the uninterruptible power supply, and whether the external power supply stops inputting the electric energy to the uninterruptible power supply or not is determined by the voltage change on the power supply line. In addition, the electric energy required by the voltage monitor in the working process can be obtained from the connected controller, and the electric energy on the controller is supplied by the uninterruptible power supply.
Optionally, after receiving the power-off alarm information from the voltage monitor 105, the controller 101 may determine whether a person is in the detection area at the current time according to the received vital sign information, may determine whether a person is in the detection area at the latest end time according to the previously received vital sign information, and further determine whether a person is in an area adjacent to the detection area after a disaster such as an earthquake or an explosion occurs. Specifically, the controller 101 transmits installation position information of the fire detector 20 to at least one rescue terminal 30 in a wireless communication manner through the wireless communication module 103 when receiving power-off alarm information from the voltage monitor 105 and determining that a person is in a detection area within a preset time period elapsed from the reception of the power-off alarm information according to the vital sign information transmitted from the life detector 102.
For the same fire detector, the detection area corresponding to the installation position is a relatively fixed area, and people can move, so that people can enter the area adjacent to the detection area through the detection area in a period of time before the occurrence of disasters such as earthquake, explosion and the like, and the people are trapped in the area adjacent to the detection area after the occurrence of the disasters such as earthquake, explosion and the like. After receiving the power-off alarm information, the controller 101 determines whether people are in the detection area within a recent period of time according to the received vital sign information, and then determines whether people are trapped in the area within a certain distance range from the installation position of the fire detector 20, so that after determining that people are in the detection area within the recent period of time, the installation position information of the fire detector 20 is sent through the wireless communication module 103, and the rescue personnel is informed that people are in the area near the installation position of the fire detector 30, and the efficiency of rescuing the trapped people in disasters such as earthquakes, explosions and the like is further improved.
For example, after receiving the power outage alarm information, the controller 101 determines whether a person is in the detection area within the past 30 seconds according to the vital sign information received within the past 30 seconds, if so, it indicates that a person is trapped in an area that is not longer than 30 seconds after the power outage (disaster such as earthquake, explosion, etc.) occurs, and then the controller 101 sends the installation position information of the fire detector 20 to the rescue terminal 30 by using the wireless communication module 103.
Optionally, on the basis of the rescue assisting apparatus 10 shown in fig. 3, after receiving the fire alarm information or the power failure alarm information, the controller 101 needs to determine whether there is a person in a detection area corresponding to the installation location of the fire detector within a recent period of time according to the vital sign information sent by the life detector, and this process specifically has the following two implementation manners:
the first method is as follows: after receiving the fire alarm information or the power failure alarm information, processing the vital sign information to determine whether a person exists in a detection area within a recent period of time;
the second method comprises the following steps: and processing the vital sign information periodically, judging whether people exist in the detection area in each period, covering and storing the judgment result, and determining whether people exist in the detection area according to the stored judgment result after receiving the fire alarm information or the power failure alarm information.
The following two ways of determining whether a person is in the detection area are described separately:
aiming at the first mode:
the controller 101 receives and stores the vital sign information sent by the vital detector 102, wherein the stored vital sign information is the vital sign information received within a preset target time period from the current time, and the received vital sign information outside the target time period is covered by the newly received vital sign information. For example, if the preset target time period is 1 minute, the controller 101 stores only the vital sign information received within the latest 1 minute, and when the newly received vital sign information is stored, the oldest stored vital sign information is automatically overwritten.
When the controller 101 receives the fire alarm information from the fire detector 20 or receives the power-off alarm information from the voltage monitor 105, the controller 101 determines whether or not a person is present in the detection area within a lapse of a certain period of time from the time when the corresponding alarm information is received, based on the already stored vital sign information. For example, the controller 101, upon receiving the fire alarm information from the fire detector 20, determines whether or not there is a person in the detection area within the last 1 minute based on the already stored vital sign information.
In an embodiment of the invention, the controller stores the vital sign information for a span time equal to the length of the target time period, which determines the maximum interval between the time of the presence of a person in the detection area and the time of the occurrence of a disaster, which determines the distance between the person and the fire detector, which triggers the event of transmitting the installation location information of the fire detector. Therefore, in the actual service implementation process, the length of the target time period can be flexibly determined according to factors such as the room layout near the installation position of the fire detector, the movement speed of people and the like.
In the second embodiment:
the early warning duration is preset, and when the controller 101 receives the vital sign information from the vital detector 102, whether a person is in a detection area within the early warning duration is determined according to the vital sign information received within the early warning duration every time one early warning duration passes, and the determined detection result is stored. Specifically, when the detection result is stored, the detection result determined for the current early warning duration may automatically cover the detection result determined for the previous early warning duration, and it is ensured that only one detection result is stored on the controller 101 at the same time. For example, if the preset early warning duration is equal to 1 minute, the controller 101 determines whether a person is in the detection area or not according to the vital sign information received in the 1 minute every 1 minute, stores the determined detection result, and overwrites the previously stored detection result when storing the detection result.
After the controller 101 receives the fire alarm information from the fire detector 20 or receives the power-off alarm information from the voltage monitor 105, the controller 101 determines whether the stored detection result indicates that someone is in the detection area, and if the stored detection result indicates that someone is in the detection area, the controller 101 transmits the installation position information of the fire detector 20 to at least one rescue terminal 30 through the wireless communication module 103 in a wireless communication manner. For example, after receiving the power-off alarm information from the voltage monitor 105, the controller 101 determines that a person is in the detection area based on the detection result determined 30 seconds ago, and then transmits the installation position information of the fire detector 20 to the rescue terminal 30 through the wireless communication module 103 in a wireless communication manner.
In the embodiment of the invention, the controller determines the detection result according to the vital sign information before receiving the fire alarm information or the power-off alarm information, and can immediately determine whether the installation position information of the fire detector needs to be sent according to the detection result after receiving the fire alarm information or the power-off alarm information, so that the reaction time of the detector can be shortened, the position of the trapped person can be reported more quickly after a disaster occurs, and the efficiency of rescuing the trapped person is further improved.
It should be noted that, in the rescue assistance device 10 provided in each of the above embodiments, the life detector 102 is disposed adjacent to the fire detector 20, and the detection region corresponding to the installation position of the fire detector 20 refers to a range in which the life detector 102 can effectively detect the vital sign characteristics of a person, that is, a region near the fire detector 20.
Alternatively, on the basis of the co-rescue assisting apparatus 10 provided in the above-mentioned embodiments, the life detector 102 may be any one or more of a passive infrared detector, a sound detector and a radar detector.
Thermal radiation is generated by any object in nature, and the spectrum generated by thermal radiation lies mainly in the infrared band, and the temperature of the surface of an object is related to the wavelength of infrared rays radiated by the object. The passive infrared detector can passively receive infrared rays radiated from an object and recognize the wavelength of the received infrared rays. Therefore, after receiving the infrared rays radiated by the object in the detection area, the passive infrared rays can determine whether the received infrared rays include the infrared rays radiated by the human body according to the preset wavelength range of the infrared rays radiated by the human body, and further determine whether a person exists in the detection area and generate corresponding vital sign information. Utilize passive form infrared detector, as long as there is the animate person in the detection area, alright in order to detect vital sign information to also can detect the stranded personnel when stranded personnel fall, lose consciousness, and then can in time inform the rescue personnel to rescue the stranded personnel.
The sound detector can generate vital sign information according to the distress call sound or the hitting sound of the person, and can determine the distance between the trapped person and the fire detector according to the strength of the sound, so that when the trapped person calls for help or sends a distress signal through hitting, the sound detector can generate the vital sign information and send the vital sign information to the controller, and the rescue person can quickly find the trapped person for rescue according to the installation position of the fire detector.
The radar detector can identify the breath or heartbeat of a human body by sending radar signals and according to the reflected radar signals, so that vital sign information can be generated and sent to the controller after a person enters a detection area.
