Fire refers to the disaster caused by burning out of control in time or space. Among various disasters, fire is one of the main disasters that most often and most commonly threaten public safety and social development. With the development of science and technology, fire safety has attracted more and more attention, and people's demand for "smart fire protection" is also increasing. In the "smart fire protection" scenario, it is required to quickly detect and respond to fire situations.

In the prior art, a camera is usually used to monitor an area to be detected, a video collected by the camera is obtained, and fire identification and analysis are performed on the video, so as to determine the occurrence of the fire. The problem with the prior art is that when performing fire identification and analysis based on the video collected by the camera, a large amount of video data needs to be transmitted, and the transmission time is long, which affects the detection efficiency and real-time performance. Moreover, the transmission quality of video data is easily affected by the network, thus affecting the accuracy of fire detection.

At present, urban fire warning systems mostly collect fire warning information through cameras. However, the fire analysis and identification system based on the video collected by the camera is easily affected by factors such as the installation position and angle of the camera. At the same time, the area observed by the camera is limited, which leads to a high rate of false positives and untimely early warning in the fire early warning system based on video analysis. At the same time, in order to ensure the transmission efficiency and quality of video data, data transmission is usually carried out by means of wired transmission, resulting in the camera can only be installed in certain preset fixed positions, the number of installations is limited, and cannot be easily adjusted, resulting in fires The detection area is limited and it is inconvenient to adjust the area range, which is not conducive to fire detection and early warning. Moreover, the wiring is easily affected by the actual environment, and it is inconvenient to adjust. In some environments, it is inconvenient to perform wiring, which affects fire detection. Furthermore, at present, the accuracy of fire detection based on video images is not high, and manual assistance is often required, that is, the equipment cannot accurately determine whether a fire has actually occurred through video images, and it needs to be sent to the staff for further judgment, which requires a lot of manpower. Moreover, based on the video images, the area where the fire occurred cannot be obtained, and the scope of the fire 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 obtains the connection request information sent by the target fire detection sensor in real time through the wireless base station, wherein the above target fire detection sensor is a fire detection method in the area to be detected A fire detection sensor that detects the occurrence of a fire; obtains the fire information of the area to be detected based on all the above connection request information; and performs a fire warning based on the above fire information. Compared with the scheme in the prior art that needs to receive video data collected by the camera and perform fire identification and analysis based on the video data, the present invention only needs to obtain the connection request information sent by the target fire detection sensor to obtain the fire information of the area to be detected . Compared with video data information, connection request information has small data volume, easy transmission and fast transmission speed, and the transmission quality is not easily affected by the network. Fire Safety.

At the same time, data transmission can be carried out through the wireless network, there is no problem that the wiring is affected by the environment, and the position and number of fire detection sensors can be easily adjusted to better adapt to various environments and perform fire detection in the area to be detected. And there is no need for manual checking, which is conducive to saving human resources.

exemplary method

As shown in Figure 1, an embodiment of the present invention provides a fire detection method, specifically, the fire detection method includes the following steps:

In step S100, the wireless base station acquires the connection request information sent by the target fire detection sensor in real time, wherein the target fire detection sensor is a fire detection sensor that detects a fire in the area to be detected.

Wherein, the above-mentioned area to be detected is an area that requires 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 in various scenarios, for example, it can be a family, Shopping malls, office buildings or underground pipelines can also perform fire detection on multiple areas in multiple scenarios at the same time.

The wireless network coverage is realized through the wireless base station in the above-mentioned to-be-detected area, and a plurality of fire detection sensors are set in the above-mentioned to-be-detected area. When the fire detection sensor detects a fire, it can connect to the wireless base station to request information to prompt the location There was a fire. It should be noted that the above-mentioned fire detection sensors detect in real time, but do not need to connect and communicate with the wireless base station when no fire is detected, which can further reduce the occupation of network resources, thereby also improving the efficiency of information transmission by other target fire detection sensors .

In this embodiment, the above-mentioned wireless base station is a femtocell (femtocell). Specifically, a femtocell is an ultra-miniature mobile base station that can provide a home-level wireless access node, and the femtocell has low power, convenient access, low cost and The advantages of short-distance wireless communication quality are stable. In this embodiment, the femtocell is used as the wireless base station, which can be arranged flexibly, which is beneficial to improve the efficiency and quality of data transmission, thereby improving the efficiency, real-time performance and accuracy of fire detection, and can reduce costs.

In one application scenario, multi-femtocell hotspots can be laid out and connected in advance according to actual scenarios (such as application environments such as homes, shopping malls, office buildings, and relatively closed underground pipelines), so that wireless coverage in the entire area can be achieved in this application scenario, thereby improving Accuracy of fire detection.

Specifically, in this embodiment, as shown in FIG. 2, before the above step S100, the above method further includes:

Step A100, setting all the above-mentioned fire detection sensors to different positions of the above-mentioned to-be-detected area respectively.

Step A200, respectively register the ID information of each fire detection sensor with at least one access point of the wireless base station.

Specifically, in this embodiment, a plurality of fire detection sensors are respectively arranged in different positions of the area to be detected in advance, so as to realize fire detection at each position. Furthermore, the corresponding relationship between the ID information and the location of each fire detection sensor can also be recorded, so that when the ID information of the fire detection sensor is obtained, the location of the fire sensor can be known, so as to know the location of the fire.

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 obtains the access request information, the location of the corresponding fire detection sensor can be quickly obtained according to the ID information. In an application scenario, the ID information of each fire detection sensor can be registered to the nearest preset number of femtocell access points, thereby improving the efficiency of obtaining access request information. Specifically, the above-mentioned preset number can be pre-set according to the actual situation, and the preset number of each location can also be adjusted according to the actual environment. For example, for a location that needs to be detected intensively (such as an archive room), set a higher preset number for the fire detection sensor in that location.

It should be noted that, in this embodiment, the above-mentioned fire detection sensor is a smoke detector, and the above-mentioned smoke detector has functions of smoke detection and wireless transmission, and the above-mentioned smoke detector can perform wireless communication and connection with a femtocell hotspot. Further, the above-mentioned smoke detector is initially in a real-time detection state, that is, it can detect in real time whether a fire occurs at the current location, and if no fire is detected, the above-mentioned smoke detector does not need to be connected and communicated with the corresponding femtocell, which can reduce The occupancy of network bandwidth ensures the communication of other smoke detectors or other devices that need to communicate.

Further, in this embodiment, the communication between the above-mentioned smoke detector and the femtocell hot spot is a wireless communication mode, so it is convenient to deploy the installation method, location and quantity of the sensor (smoke detector) according to the actual application scenario, and effectively realize the specified There are relevant fire detection points at all key positions of the site. Moreover, the sensor installation location can be dynamically updated in real time without changing the configuration. At the same time, new sensor devices can be added and installed in real time, and only the corresponding sensor ID information needs to be added to the femtocell, thereby facilitating the maintenance and update of the entire system and effectively realizing the whole area. Covered fire detection.

In this embodiment, the above-mentioned smoke detector acquires fire judgment information based on the smoke concentration at the current location. Specifically, when the smoke detector detects that the smoke density value at the current location is higher than the preset smoke density threshold value, fire occurrence is used as fire judgment information, and sends connection request information to the wireless base station. Wherein, the above-mentioned smoke concentration threshold is a preset value, which can be set and adjusted according to the actual environment and needs. When the smoke concentration value detected at the current location is too high, it can be determined that the current location is on fire.

Further, when the smoke detector detects the occurrence of a fire (that is, when the fire judgment information indicates the occurrence of a fire), the connection operation is started, and the connection request information is actively sent to the corresponding femtocell base station. Specifically, the smoke detector sends connection request information through one or more nearest femtocell access points, so that the femtocell can learn the fire situation in time.

Specifically, in this embodiment, the above-mentioned smoke detector only needs to send connection request information, and does not need to send other specific information content, and the data volume is small, so the transmission speed is also fast, which is beneficial to improve the fire detection efficiency. At the same time, according to the ID information in the connection request information of each smoke detector, the location information of the corresponding smoke detector can be obtained (the location is preset, and can be associated with the ID information after setting). Dangdang femtocell receives When a smoke detector access request is received, it can be considered that the relevant sensor has detected fire information, thereby greatly improving the efficiency of fire detection, and the location of the fire can be known.

It should be noted that, in this embodiment, the above-mentioned fire detection sensor is a smoke detector. During actual use, other sensors for detecting fire can also be selected, such as a temperature sensor, which is not specifically limited here.

Step S200, acquiring fire information in the area to be detected based on all the connection request information.

Wherein, the above-mentioned fire information is information used to reflect the fire situation in the area to be detected. Specifically, the above fire information may include fire location information and fire area information.

Specifically, in this embodiment, as shown in FIG. 3, the above step S200 specifically includes the following steps:

Step S201 , based on all the connection request information, the ID information of all the target fire detection sensors and the quantity of the target fire detection sensors are acquired.

Step S202, acquiring fire location information based on the above ID information.

Step S203, acquiring fire area information based on the number of target fire detection sensors and the fire location information.

Step S204, using the fire location information and the fire area information as the fire information.

Specifically, in this application, ID information of target fire detection sensors corresponding to all connection request information is obtained, and the number of target fire detection sensors can be obtained according to the number of connection request information. It should be noted that multiple pieces of connection request information (that is, connection request information with the same ID information) of the same fire detection sensor are regarded as one connection request information.

Further, fire location information corresponding to each target fire detection sensor is acquired according to the ID information and the pre-stored mapping relationship between ID information and location information.

Meanwhile, fire area information is acquired based on the statistical number of target fire detection sensors and the above fire location information. For example, the area of the fire can be preliminarily determined according to the number of fire detection sensors and the preset average distance between the fire detection sensors. Then according to the area of preliminary judgment, the average distance between the preset fire detection sensors and the above-mentioned fire location information, it is judged whether the fire area needs to be divided into blocks (that is, whether it needs to be divided into multiple fire area blocks. Then according to the target of the edge of each block The position information of the fire detection sensor constructs the edge profile of the block, and obtains the area of each fire area block according to the edge profile, so as to obtain the fire area information (for example, it can be the sum of the areas of all fire area blocks).

It should be noted that, in an application scenario, the fire area information may also be obtained only according to the fire location information or only according to the number of target fire detection sensors. In another application scenario, the fire area information can be obtained according to the fire location information and the number of target fire detection sensors respectively, and then the average of the fire area information obtained through the two is used as the actual fire area information.

Preferably, the above connection request information can also be sent to the data processing center through the femtocell for analysis and processing, or the femtocell can be used for analysis and processing, and the corresponding fire information can be sent to the data processing center for fire warning.

Step S300, perform fire warning based on the above fire information.

Specifically, according to the fire information, the specific occurrence of the fire can be judged, so as to perform fire warning. For example, fire warning is carried out through voice broadcast, display screen display and flashing light alarm.

Specifically, in this embodiment, as shown in FIG. 4, the above step S300 specifically includes the following steps:

Step S301, based on the fire area information and the preset fire level area threshold, the fire warning level is obtained.

Step S302, sending the above-mentioned fire warning level and the above-mentioned fire information to a preset mobile terminal.

Wherein, the above-mentioned fire level area threshold is the area threshold corresponding to each fire warning level set in advance, for example, the first level fire corresponds to the first area threshold, and the second level fire corresponds to the second level area threshold, so, according to the fire area information The current fire warning level can be judged, and the warning can be carried out according to the preset warning operations of each level, for example, different fire warning operations are set in advance for different fire warning levels. It should be noted that in an application scenario, different fire level area thresholds can also be set for different specific scenarios or areas. For example, compared with densely populated areas and sparsely populated areas, the area thresholds corresponding to the same level can be Smaller, so the fire warning level can be obtained through the fire location information, fire area information and the preset fire level area threshold.

In this way, the femtocell actively sends a fire warning to the relevant big data processing center and starts the fire warning. Moreover, femtocell can accurately locate the fire location according to the ID information of the smoke detector, and can judge the fire area according to the reported smoke detection quantity information, so it can better judge the fire severity and activate different warning levels.

Further, in this embodiment, the above-mentioned fire warning level and corresponding fire information can also be sent to a preset mobile terminal, for example, to the mobile phone of the person in charge of the corresponding place, or the mobile terminal of the fire center. Specifically, when the femtocell detects fire information, it can also send the relevant information to the designated mobile phone (such as the mobile phone of the person in charge of the relevant place) through the wireless network, so as to realize multi-channel fire early warning, which is conducive to timely fire control.

It can be seen that in this embodiment, the connection request information sent by the target fire detection sensor is obtained in real time through the wireless base station, wherein the target fire detection sensor is a fire detection sensor that detects a fire in the area to be detected; based on all the above connection request information Obtain the fire information of the above-mentioned area to be detected; perform fire warning based on the above-mentioned fire information. Compared with the scheme in the prior art that needs to receive video data collected by the camera and perform fire identification and analysis based on the video data, the present invention only needs to obtain the connection request information sent by the target fire detection sensor to obtain the fire information of the area to be detected . Compared with video data information, connection request information has small data volume, easy transmission and fast transmission speed, and the transmission quality is not easily affected by the network.
