As shown in fig. 2, the method comprises the steps of:
s101, when detecting that the fire prevention and control data exceeds a preset safety value, the target detection device sends alarm request information with a target host identification to a corresponding target host.
Wherein, the fire prevention and control data are temperature, smoke concentration and/or combustible gas concentration.
Specifically, a plurality of detection devices are installed in each floor of the building, each detection device is provided with a corresponding detection area respectively so as to realize multi-directional detection of each floor, and in addition, a host is arranged in each floor and is connected with the plurality of detection devices in a matching mode.
The detection device comprises a temperature sensor, a smoke concentration sensor and a combustible gas concentration sensor; the temperature sensor is used for detecting the temperature value in the building in real time, the smoke concentration sensor is used for detecting the smoke concentration value in the building in real time, the combustible gas concentration sensor is used for detecting the combustible gas concentration in the building in real time, and when the temperature value is larger than a preset temperature value, when the smoke concentration value is larger than the smoke concentration value, and when the combustible gas concentration is larger than the preset combustible gas concentration value, the detection device gives an alarm to a host machine matched with the detection device. Taking the target detection device as an example, when the target detection device detects that the fire prevention and control data exceeds the preset security value, the target detection device may send alarm request information with a target host identifier to a target host paired with the target detection device.
S102, the target host forwards the received alarm request information to an alarm processing center.
Specifically, an alarm processing center is arranged in the building, the alarm processing center is in communication connection with each host in the building, and the alarm processing center is used for receiving alarm request information. Therefore, the target host can forward the received alarm request information to the alarm processing center after detecting the alarm of the target detection device.
S103, the alarm processing center obtains the target host identification in the alarm request information and determines the target background management terminal corresponding to the target host identification.
Specifically, in the building system, one or more background management personnel can be set for each host, the background management personnel can supervise and respond to the host, and correspondingly, the host and the terminal (i.e., the background management terminal) of the background management personnel can be bound, and the binding result is recorded at the alarm processing center in a manner of correspondingly storing the host identifier and the terminal identifier. Therefore, after receiving the alarm request information sent by the target host, the alarm processing center can acquire the target host identifier in the alarm request information, and determine the target background management terminal bound with the target host according to the target host identifier in the binding result.
And S104, the alarm processing center forwards the alarm request information to the target background management terminal.
Specifically, the alarm processing center sends the received alarm request information to the target background management terminal, so that background management personnel can timely know that fire exists in a building even if the background management personnel are not near a fire area or even far away from the building, and the fire early warning way and range are enlarged. Furthermore, the background management personnel can specify rescue measures in time according to the alarm request information, and people in the building can escape in time; in addition, the alarm request information is sent to the background management terminal corresponding to the target host identification, and the background management terminal can substantially determine the position of fire in the building when receiving the alarm request information, so that the fire relief personnel can quickly find the area with the fire, and the rescue efficiency is improved.
In one embodiment, to facilitate timely escape of personnel within a building. The fire-fighting early warning system further comprises alarm bells, a plurality of alarm bells are installed on each floor in the building, the alarm bells are in one-to-one correspondence with the detection devices, and the alarm bells on each floor are in communication connection with the host machine on each floor.
After the target detection device sends the alarm request information with the target host identifier to the corresponding target host, the following processes may also exist:
the target host acquires the alarm bell corresponding to the target detection device, and sends a trigger signal for triggering alarm of the alarm bell to the alarm bell.
Specifically, after a fire occurs, the target host receives the alarm request information sent by the target detection device, and then sends a trigger signal for triggering the alarm bell to give an alarm to the alarm bell, so that personnel in the building can know the fire occurring in the building at the first time, and the personnel in the building can escape as soon as possible.
In one embodiment, considering that when a fire occurs, in order to increase a fire early warning range, the fire early warning system further comprises an indoor person detection device, wherein the indoor person detection device comprises a moving object induction sensor and a sound sensor, the indoor person detection device is installed in each room of each floor in the building, and the indoor person detection device of each room is in communication connection with the host of the floor corresponding to the room.
After the alarm processing center forwards the alarm request information to the target background management terminal, the following processing may also exist:
when detecting that the indoor personnel activity data exceeds a preset initial value, the target indoor personnel detection device detects personnel detection information with a target host identification sent to a corresponding target host, wherein the personnel activity data are indoor moving object movement data and indoor sound decibel data;
the target host forwards the received personnel detection information to an alarm processing center;
the alarm processing center acquires a target host identification in the personnel detection information and determines a background management terminal corresponding to the target host identification;
and the alarm processing center forwards the personnel detection information to the target background management terminal.
Specifically, after a fire occurs, indoor personnel activity data are detected in real time by using a target indoor personnel detection device, for example, when no person exists in a room, an initial value of indoor moving object movement data is 0 for a moving object induction sensor, and an initial value of indoor sound can be set to be an environmental noise value for a sound sensor in consideration of the existence of environmental noise in the room, so that the preset initial value of indoor personnel activity data is consistent with the environmental noise value; when the detected indoor personnel activity data exceeds a preset initial value, the indoor personnel activity phenomenon is represented, and at the moment, the target indoor personnel detection device detects personnel detection information with a target host identification sent to the corresponding target host; then the target host forwards the received personnel detection information to the alarm processing center, the alarm processing center can find the background management terminal corresponding to the target host identifier according to the target host identifier, so that the alarm processing center can forward the personnel detection information to the target background management terminal, and background management personnel can arrange accurate rescue measures according to the personnel detection information.
In one embodiment, the phenomenon that the detection data is inaccurate due to the fact that the target detection device is damaged in performance is considered, and therefore the alarm request information forwarded to the target background management terminal by the alarm processing center is false alarm. Before the alarm processing center forwards the alarm request information to the target management background management terminal, the following steps can be further implemented:
the alarm processing center receives alarm removing information with a target host identification sent by a target host;
the alarm processing center acquires a target host identifier in the alarm release information and determines a target background management terminal corresponding to the target host identifier;
and the alarm processing center contact forwards alarm release information to the target background management terminal.
Specifically, in order to determine whether the alarm request information is a false alarm, personnel in the building can go to a detection area pointed by the alarm request information to check whether a fire exists in real time, if no fire exists, the alarm request information is a false alarm, and at the moment, the personnel in the building can send alarm release information to an alarm processing center through a host; the alarm removing information carries a target host identifier, the alarm processing center can determine a target background management terminal corresponding to the target host identifier according to the target host identifier, so that the alarm processing center can forward the alarm removing information to the target background management terminal, and background management personnel can know that the phenomenon that a fire condition exists in a building is false alarm.
In one embodiment, it is considered that the data detected by the target detection device may be inaccurate, so that the alarm request information forwarded by the alarm processing center to the target background management terminal is a false alarm phenomenon. The building fire-fighting early warning system further comprises a picture acquisition device, and the alarm request information also carries an area identifier.
Before the alarm processing center forwards the alarm request information to the target management background management terminal, the following processes can be executed:
the alarm processing center acquires an actual picture of a detection area corresponding to the area identification through the target picture acquisition device;
the alarm processing center compares the actual picture with a pre-stored safety picture of the detection area, and judges whether the actual picture is consistent with the safety picture according to the comparison result;
and if the actual picture is inconsistent with the safety picture, judging that the fire condition exists in a detection area corresponding to the target detection device in the alarm request information.
Specifically, a plurality of picture acquisition devices are installed in each floor of the building, the picture acquisition devices correspond to the detection devices one by one respectively, and the picture acquisition devices can be monitoring cameras; when the alarm processing center receives an alarm sent by a target host, the alarm processing center firstly acquires an actual picture in a detection area through a target picture acquisition device, and then compares the actual picture with a pre-stored safety picture in the detection area, wherein the safety picture is a normal picture in a building, namely a picture of the detection area when no fire exists; and then judging whether the actual picture is consistent with the safety picture or not according to the comparison result, if the actual picture is inconsistent with the safety picture, judging that the fire exists in a detection area corresponding to the target detection device in the alarm request information, and thus verifying the authenticity of the fire in the detection area.
In an embodiment, the comparison between the actual image and the safety image may be implemented by comparing the flame region, and the processing of comparing the actual image with the safety image in the pre-stored detection region by the alarm processing center may be as follows:
the alarm processing center extracts a reference flame area in the safety picture and calculates a reference ratio between the size of the reference flame area and the size of the safety picture;
the alarm processing center extracts an actual flame area in the actual picture and calculates the actual ratio between the size of the actual flame area and the size of the actual picture;
and if the reference proportion is inconsistent with the actual proportion, judging that the safety picture is inconsistent with the actual picture.
Specifically, when the actual picture is compared with the safety picture and the alarm processing center compares the actual picture with the safety picture, the alarm processing center firstly extracts the size of a reference flame region in the safety picture and calculates the reference ratio between the size of the reference flame region and the size of the safety picture; in a normal state of the safety picture, the safety picture does not have a fire source area, but the situation that the safety picture has a fixed fire source is not excluded, and at the moment, the safety picture has the fire source area; and then the alarm processing center extracts the size of the actual flame area of the actual picture, calculates the actual ratio between the size of the actual flame area and the size of the actual picture, and judges that the safety picture is inconsistent with the actual picture if the reference ratio is inconsistent with the actual ratio, namely the risk of fire possibly exists in the detection area.
In one embodiment, in view of facilitating a background manager to monitor the fire spreading condition in the detection area in real time, after determining that the safety picture is inconsistent with the actual picture, the following steps may be further performed:
after a preset time period, the alarm processing center receives a rechecking picture of the detection area sent by the target picture acquisition device;
the alarm processing center extracts a rechecking flame region in the rechecking picture and calculates the rechecking ratio between the size of the rechecking flame region and the size of the rechecking picture;
judging whether the actual occupation ratio is smaller than the rechecking occupation ratio or not; if yes, calculating the ratio difference between the actual ratio and the rechecking ratio, and if the ratio difference is larger than a preset ratio initial value, judging that the fire condition in the detection area has a trend of increasing;
and the alarm processing center forwards the risk early warning with the increased fire condition to the target background management terminal.
Specifically, after the security picture is judged to be inconsistent with the actual picture, after a preset time period, for example, 30 seconds, the target picture acquisition device takes a picture of the detection region again to obtain a rechecked picture, and sends the rechecked picture of the detection region to the alarm processing center; and then the alarm processing center extracts a flame area in the rechecking picture, wherein the flame area can be the rechecking flame area, the rechecking ratio between the size of the rechecking flame area and the size of the rechecking picture is calculated, when the actual ratio is smaller than the rechecking ratio, the ratio difference between the actual ratio and the rechecking ratio is calculated, if the ratio difference is larger than a preset ratio initial value, the trend that the fire condition in the detection area is increased is judged, at the moment, the alarm processing center forwards a risk early warning with the increased fire condition to the target background management terminal to remind background management personnel to make corresponding rescue measures according to the risk early warning, and the personnel in the building can escape in time.
In an embodiment, the above-mentioned method for comparing the actual picture with the security picture may also adopt a method for comparing picture brightness, and the alarm processing center compares the actual picture with the security picture of the pre-stored detection area, and specifically may implement the following steps:
the alarm processing center acquires an actual brightness value in an actual picture;
the alarm processing center acquires a reference brightness value in the security picture;
the alarm processing center calculates a brightness difference value between the actual brightness value and the reference brightness value;
judging whether the brightness difference value is within a pre-stored difference value range; if not, the safe picture is judged to be inconsistent with the actual picture.
Specifically, when the actual picture and the safety picture are compared, the alarm processing center respectively obtains an actual brightness value in the actual picture and a reference brightness value in the safety picture, then a brightness difference value between the actual brightness value and the reference brightness value is calculated, if the brightness difference value is out of a pre-stored difference value range, the safety picture and the actual picture are judged to be inconsistent, namely, the risk of fire possibly exists in the detection area.
In addition, because the picture collecting device has dead corners and is not shot, and when a fire exists in the dead corners, the actual picture is consistent with the object environment in the safe picture, so that the dead corners have real fire and cannot give an alarm; when a fire occurs at the dead corner of the picture acquisition device, the brightness value of the actual picture shot by the picture acquisition device can be increased, and then the actual brightness value of the actual picture is larger than the reference brightness value of the safety picture.
In one embodiment, after determining that a fire occurs in a detection area corresponding to the target detection device in the alarm request information, in consideration of the fact that when a fire occurs in the building, people in the building are easy to be confused during escape, so that the optimal escape time is missed, the method further comprises:
the alarm processing center calls a building interior topographic map in a pre-stored database;
the alarm processing center counts the detection areas with fire in the building, and marks the detection areas with fire in the building in the interior topographic map of the building to obtain the interior topographic map of the building;
and the alarm processing center plans corresponding escape routes and rescue routes for each detection area in the building according to the fire topographic map.
Specifically, the interior topographic map of the building can be provided with the identification of the number of floors of each floor in the building, the identification of a detection area in each floor and the identifications of all safety exits in the building; when fire occurs in the building, all detection devices in the building send alarm request information to an alarm processing center through a host for detecting the detection areas with the fire, the alarm processing center can count all the detection areas with the fire in the building, the detection areas with the fire in the building are marked in a topographic map in the building so as to generate a topographic map of the fire, and the alarm processing center can avoid the detection areas with the fire according to the topographic map of the fire so as to plan corresponding escape routes and rescue routes for all the detection areas in the building, so that rescue personnel can arrange rescue methods in time, and people in the building can escape in time.
In one embodiment, the problem is difficult to find in view of the fire risk in the room.
