Fire is a disaster caused by burning which is out of control in time or space, and among various disasters, fire is one of the most frequent and most common disasters threatening public safety and social development. With the development of scientific technology, fire safety is receiving more and more attention, and people are also getting more and more high to "intelligent fire fighting", and under the scene of "intelligent fire fighting", the quick detection and response to the conflagration condition are required.
In the prior art, a region to be detected is monitored through a camera, a video acquired by the camera is obtained, and fire disaster identification and analysis are performed on the video, so that the occurrence condition of the fire disaster is determined. The problem in the prior art is that when fire disaster identification and analysis are carried out based on video acquired by a camera, a large amount of video data needs to be transmitted, the transmission time is long, and the detection efficiency and the instantaneity are affected. And the transmission quality of video data is easily affected by the network, thereby affecting the accuracy of fire detection.
At present, urban fire early warning systems collect fire early warning information through cameras. However, the fire analysis and recognition system based on video captured by the camera is susceptible to factors such as the mounting position and angle of the camera. Meanwhile, the area observed by the camera is limited, so that the fire early-warning system based on video analysis is high in missing report rate and untimely in early warning. Meanwhile, in order to ensure the transmission efficiency and quality of video data, a wired transmission mode is generally adopted for data transmission, so that a camera can only be installed at certain preset fixed positions, the installation quantity is limited, and adjustment cannot be conveniently carried out, thereby the area range of fire detection is limited, the area range is inconvenient to adjust, and the fire detection and early warning are not facilitated. And wiring is easily affected by the actual environment, so that the adjustment is inconvenient, and the wiring is inconvenient in some environments, so that the fire detection is affected. Furthermore, the accuracy of fire detection based on video pictures is not high at present, manual assistance is often needed, that is, whether the fire really happens or not can not be accurately determined through the video pictures by equipment, and the fire is further judged by sending the fire to staff, so that a large amount of manpower is needed to be consumed. And the area of the area where the fire disaster occurs cannot be obtained based on the video picture, and the influence range of the fire disaster cannot be accurately known.
In order to solve at least one problem in the prior art, the present invention provides a fire detection method, which acquires connection request information sent by a target fire detection sensor in real time through a wireless base station, wherein the target fire detection sensor is a fire detection sensor that detects a fire occurrence in an area to be detected; acquiring fire information of the area to be detected based on all the connection request information; and carrying out fire early warning based on the fire information. Compared with the scheme in the prior art that video data acquired by a camera are required to be received and fire disaster identification and analysis are carried out based on the video data, the fire disaster information of the area to be detected can be acquired only by acquiring the connection request information sent by the target fire disaster detection sensor. Compared with video data information, the connection request information has the advantages of small data size, easy transmission and high transmission speed, and simultaneously the transmission quality is not easily affected by a network, so that the efficiency, the instantaneity and the accuracy of fire detection are improved, and the fire safety is improved.
Meanwhile, the wireless network is used for data transmission, the problem that wiring is affected by the environment does not exist, the position and the number of the fire detection sensors can be conveniently adjusted, and the wireless network fire detection system is better suitable for various environments and performs fire detection on an area to be detected. And the manual checking is not needed, which is beneficial to saving human resources.
Exemplary method
As shown in fig. 1, an embodiment of the present invention provides a fire detection method, specifically, the fire detection method includes the following steps:
step S100, acquiring connection request information sent by a target fire detection sensor in real time through a wireless base station, wherein the target fire detection sensor is a fire detection sensor detecting fire occurrence in a region to be detected.
The area to be detected is an area needing fire detection, in this embodiment, a wireless network is used for data transmission, so the area to be detected is not limited by the environment, and can be an area under various scenes, for example, a home, a mall, an office building or an underground pipeline, and fire detection can be performed on a plurality of areas under a plurality of scenes at the same time.
The coverage of the wireless network is realized through the wireless base station in the area to be detected, and a plurality of fire detection sensors are arranged in the area to be detected, and when the fire detection sensors detect the occurrence of a fire, the request information can be connected with the wireless base station to prompt that the fire occurs at the position. The fire detection sensor detects the fire in real time, but does not need to be connected and communicated with a wireless base station when the fire is not detected, so that the occupation of network resources can be further reduced, and the information transmission efficiency of other target fire detection sensors can be improved.
In this embodiment, the wireless base station is a femtocell (femtocell), and in particular, the femtocell is a microminiaturized mobile base station, which can provide a home-class wireless access node, and the femtocell has the advantages of low power, convenient access, low cost, stable quality of short-range wireless communication, and the like. In this embodiment, femtocell is adopted as a wireless base station, so that the femtocell can be flexibly arranged, and the data transmission efficiency and quality can be improved, thereby improving the fire detection efficiency, instantaneity and accuracy, and reducing the cost.
In an application scene, multiple femtocell hot spots can be laid out and connected in advance according to actual scenes (such as application environments of families, markets, office buildings, relatively closed underground pipelines and the like), so that full-area wireless coverage is realized in the application scene, and the accuracy of fire detection is improved.
Specifically, in this embodiment, as shown in fig. 2, before the step S100, the method further includes:
and step A100, respectively setting all the fire detection sensors to different positions of the to-be-detected area.
Step A200, registering the ID information of each fire detection sensor to at least one access point of the wireless base station.
Specifically, in this embodiment, a plurality of fire detection sensors are arranged in advance at different positions of an area to be detected, respectively, to realize fire detection at each position. Further, the correspondence relationship between the ID information of each fire detection sensor and the position may be recorded, so that the position of the fire sensor can be obtained when the ID information of the fire detection sensor is obtained, and the position of the fire can be obtained.
In this embodiment, the ID information of each fire detection sensor is registered to at least one access point of the femtocell, so that when the wireless base station acquires the access request information, the position of the corresponding fire detection sensor can be quickly acquired according to the ID information. In one application scenario, the ID information of each fire detection sensor may be registered to a preset number of femtocell access points closest to the fire detection sensor, thereby improving the efficiency of obtaining access request information. Specifically, the preset number can be preset according to actual conditions, and the preset number of each position can be adjusted according to actual environments. For example, for a location requiring important detection (e.g., an archive), a higher preset number of fire detection sensors for that location is set.
In this embodiment, the fire detection sensor is a smoke detector, and the smoke detector has the functions of smoke detection and wireless transmission, and the smoke detector can be in wireless communication and connection with a femtocell hotspot. Furthermore, the smoke detector is in a real-time detection state at the beginning, so that whether a fire disaster occurs at the current position can be detected in real time, and the smoke detector does not need to be connected and communicated with the corresponding femtocell under the condition that the fire disaster is not detected, so that the occupation of network bandwidth can be reduced, and the communication of other smoke detectors or other devices needing to be communicated is ensured.
Further, in this embodiment, the communication between the smoke detector and the femtocell hotspot is a wireless communication manner, so that the installation manner, the positions and the number of the sensors (smoke detectors) can be conveniently deployed according to the actual application scene, and all the key positions of the designated field can be effectively provided with relevant fire detection points. In addition, the installation position of the sensor can be dynamically updated in real time without changing the configuration, and new sensor equipment can be added and installed in real time, and corresponding sensor ID information is only required to be added to the femtocell, so that the maintenance and updating of the whole system are facilitated, and the fire detection of the whole area coverage is effectively realized.
In this embodiment, the smoke detector acquires fire judgment information based on the smoke concentration at the current position. Specifically, when the smoke detector detects that the smoke concentration value at the current position is higher than a preset smoke concentration threshold value, the smoke detector takes fire occurrence as fire judgment information and sends connection request information to the wireless base station. The smoke concentration threshold is a preset value, can be set and adjusted according to actual environment and requirements, and can judge that the current position fires when the smoke concentration value detected at the current position is too high.
Further, when the smoke detector detects that a fire occurs (namely, when the fire judgment information is that the fire occurs), a connection operation is started, and connection request information is actively sent to the corresponding femtocell base station. Specifically, the smoke detector transmits connection request information through the nearest femtocell access point or multiple femtocell access points, so that the femtocell can timely acquire fire situations.
Specifically, in this embodiment, the smoke detector only needs to send connection request information, but does not need to send other specific information contents, so that the data volume is smaller, and the transmission speed is also faster, which is beneficial to improving the fire detection efficiency. Meanwhile, according to the ID information in the connection request information of each smoke detector, the position information (the position is preset and can be associated with the ID information for mapping) of the corresponding smoke detector can be obtained, when the femtocell receives the connection request of the smoke detector, the relevant sensor can be considered to detect the fire information, so that the fire detection efficiency is greatly improved, and the position of the fire can be obtained.
In this embodiment, the fire detection sensor is a smoke detector, and other sensors for detecting fire, such as a temperature sensor, may be selected in the actual use process, which is not limited herein.
Step S200, fire information of the area to be detected is obtained based on all the connection request information.
The fire information is information for reflecting the fire condition of the area to be detected. Specifically, the fire information may include fire location information and fire area information.
Specifically, in this embodiment, as shown in fig. 3, the step S200 specifically includes the following steps:
step S201, acquiring ID information of all the target fire detection sensors and the number of the target fire detection sensors based on all the connection request information.
Step S202, fire location information is acquired based on the ID information.
Step S203, acquiring fire area information based on the number of target fire detection sensors and the fire position information.
And step S204, setting the fire position information and the fire area information as the fire information.
Specifically, in the present application, ID information of the target fire detection sensors corresponding to all the connection request information is obtained, and the number of the target fire detection sensors may be obtained according to the number of the connection request information. The plurality of pieces of connection request information (i.e., the same pieces of connection request information as the ID information) of the same fire detection sensor are regarded as one piece of connection request information.
Further, fire location information corresponding to each target fire detection sensor is obtained according to the ID information and the mapping relation between the pre-stored ID information and the location information.
Meanwhile, fire area information is acquired based on the number of the target fire detection sensors counted and the fire position information. For example, the area of the fire may be primarily determined according to the number of fire detection sensors and the average distance between the fire detection sensors set in advance. And judging whether the fire area needs to be segmented (namely whether the fire area needs to be divided into a plurality of fire area blocks or not) according to the preliminarily judged area, the preset average distance between the fire detection sensors and the fire position information, then constructing the edge profile of the block according to the position information of the target fire detection sensor at the edge of each block, and acquiring the area of each fire area block according to the edge profile so as to obtain fire area information (for example, the fire area information can be the sum of the areas of all the fire area blocks).
In one application scenario, the fire area information may be acquired only from the fire position information or only from the number of target fire detection sensors. In another application scenario, fire area information may be obtained according to the fire location information and the number of target fire detection sensors, respectively, and then the fire area information obtained by the two may be averaged to obtain actual fire area information.
Preferably, the connection request information can be sent to a data processing center for analysis and processing through the femtocell, or the femtocell is used for analysis and processing, and the corresponding fire information is sent to the data processing center so as to perform fire early warning.
And step S300, performing fire early warning based on the fire information.
Specifically, the specific occurrence of the fire can be judged according to the fire information, so that fire early warning is performed. For example, fire early warning is performed by means of voice broadcasting, display screen displaying and flashing light alarming.
Specifically, in this embodiment, as shown in fig. 4, the step S300 specifically includes the following steps:
step S301, based on the fire area information and a preset fire level area threshold, a fire early warning level is obtained.
Step S302, the fire early-warning level and the fire information are sent to a preset mobile terminal.
The fire disaster level area threshold is an area threshold corresponding to each preset fire disaster early-warning level, for example, a first-stage fire disaster corresponds to a first area threshold, and a second-stage fire disaster corresponds to a second-stage area threshold, so that the current fire disaster early-warning level can be judged according to fire disaster area information, early warning can be performed according to preset early-warning operations of each level, for example, different early-warning operations are preset for different fire disaster early-warning levels. It should be noted that, in an application scenario, different fire level area thresholds may be set for different specific scenarios or areas, for example, an area threshold corresponding to the same level may be smaller in a region with dense personnel compared to a region with sparse personnel, so that a fire early warning level may be obtained through fire location information, fire area information and a preset fire level area threshold.
Thus, the femtocell actively transmits fire warnings to the relevant big data processing center and initiates fire early warning. Moreover, the femtocell can accurately position the fire position according to the ID information of the smoke detector, and can judge the fire area according to the reported smoke detection quantity information, so that the fire severity can be well judged, and different early warning levels can be started.
Further, in this embodiment, the fire early-warning level and the corresponding fire information may be sent to a preset mobile terminal, for example, a mobile phone of a responsible person in a corresponding location or a mobile terminal of a fire center. Specifically, when the femtocell detects fire information, related information can be sent to a mobile phone (such as a mobile phone of a person in charge of a related place) for realizing appointed through a wireless network, so that multi-path fire early warning is realized, and timely fire control is facilitated.
As can be seen, in this embodiment, connection request information sent by a target fire detection sensor is obtained in real time through a wireless base station, where the target fire detection sensor is a fire detection sensor that detects a fire occurrence in an area to be detected; acquiring fire information of the area to be detected based on all the connection request information; and carrying out fire early warning based on the fire information. Compared with the scheme in the prior art that video data acquired by a camera are required to be received and fire disaster identification and analysis are carried out based on the video data, the fire disaster information of the area to be detected can be acquired only by acquiring the connection request information sent by the target fire disaster detection sensor. Compared with video data information, the connection request information has the advantages of small data size, easy transmission and high transmission speed, and simultaneously the transmission quality is not easily affected by a network, so that the efficiency, the instantaneity and the accuracy of fire detection are improved, and the fire safety is improved.

The coverage of the wireless network is achieved through the wireless base station 410 in the area to be detected, and a plurality of fire detection sensors 430 are disposed in the area to be detected, and when the fire detection sensors 430 detect the occurrence of a fire, information can be requested to the wireless base station to indicate that the fire has occurred in the location. The fire detection sensor 430 detects a fire in real time, but when no fire is detected, it is not necessary to connect to or communicate with the wireless base station 410, so that occupation of network resources can be further reduced, and efficiency of transmitting information by other target fire detection sensors can be improved.
In the present embodiment, the ID information of each of the fire detection sensors 430 is registered with at least one access point of the wireless base station 410. The radio base station 410 is a femtocell (femtocell). In an application scene, multiple femtocell hot spots can be laid out and connected in advance according to actual scenes (such as application environments of families, markets, office buildings, relatively closed underground pipelines and the like), so that full-area wireless coverage is realized in the application scene, and the accuracy of fire detection is improved. The ID information of each fire detection sensor 430 is registered with at least one access point of the femtocell, so that the location of the corresponding fire detection sensor 430 can be quickly acquired according to the ID information when the wireless base station 410 acquires the access request information.
In one application scenario, if the wireless base station 410 has the functions of data processing and calculation, the wireless base station 410 may directly analyze the fire situation and acquire fire information without providing the data processor 420.

Specifically, femto close-range wireless good coverage characteristics are fully utilized, and fire detection efficiency and performance under different application scenes and difficult-to-observe environments are effectively improved. Firstly, according to femtocell access points which are not used for applying environment to control multi-point access, wireless full coverage of related application scenes is realized; then, a smoke detection transmitter with wireless access and transmission functions (with the functions of smoke detection and active access to the relevant femtocell) is installed according to the actual situation, and the ID information of the smoke detection transmitter is registered in one or more nearby femtocell access points. When the smoke detection transmitter detects fire information, the connection request is actively sent to the relevant femtocell by starting the access operation, when the relevant femtocell detects the access operation, the relevant fire detection and corresponding fire position information and the like can be sent to big data processing objects to start fire early warning, and meanwhile, the relevant information can be sent to a designated mobile phone through a wireless communication network, so that a multidirectional fire detection response mechanism is realized. Therefore, the installation and arrangement of the fire detection points (namely the fire detection sensors) can be very convenient to set according to actual application scenes without being limited by physical conditions, so that the fire monitoring of various different areas is effectively realized, and the installation positions and the quantity of the fire detection points can be changed and aligned in real time, so that the system is convenient to upgrade.
