Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

The existing fire-fighting sensor mainly comprises a photoelectric smoke detector, a temperature detector and the like. Taking a photoelectric smoke detector as an example, the photoelectric smoke detector works in the principle that a photosensitive electrode is under laser irradiation to generate an electric signal, and when fire smoke shields laser, the electrode is powered off to send out an alarm signal. The main disadvantage is the small sensor coverage area, which requires a multi-point arrangement. And the sensitivity of fire disaster identification is low, false alarm is easy to generate, the position of a fire point cannot be accurately identified and positioned, and when the fire disaster is identified, the fire extinguishing agent cannot be sprayed on combustible material classification, secondary hazard is easy to generate, and the aim of fire extinguishment is the best and the opposite.

The method aims to overcome the defects that the existing fire control detection has small coverage, low sensitivity, is easy to produce false alarm and cannot locate the fire. Referring to fig. 1, fig. 1 is a schematic structural diagram of a fire protection system according to an embodiment of the present application. As shown in fig. 1, the fire extinguishing system includes a management terminal 100, a radar apparatus 200, and a fire extinguishing apparatus 300.

The number of deployments of the radar apparatus 200 may be greater than 1. The fire suppression apparatus 300 may include a first rotary module, a second rotary module, a first spray module, and a second spray module, with a drive connection between the first rotary module and the first spray module, and a drive connection between the second rotary module and the second spray module. The first rotation module is used for moving under the driving of the management terminal 100 so as to change the pose information of the first spraying module, and the second rotation module is used for moving under the driving of the management terminal 100 so as to change the pose information of the second spraying module. The first spraying module and the second spraying module may perform fire extinguishing agent spraying based on control instructions of the management terminal 100 to accomplish fire extinguishing. Optionally, the types of the fire extinguishing agents sprayed by the first spraying module and the second spraying module can be different, and the fire extinguishing agents can be selected to extinguish fire in specific areas, so that chemical reactions of the fire extinguishing agents and other combustibles are avoided, and secondary injuries are caused.

The radar apparatus 200 is configured to collect point cloud data in a target area and transmit the collected point cloud data to the management terminal 100.

The management terminal 100 can recognize whether a fire occurs in the target area based on the point cloud data in the target area, thereby completing fire control management.

The embodiment of the application provides an electronic device, which may be the management terminal 100 shown in fig. 1. Referring to fig. 2, a schematic structure of the electronic device is shown. The electronic device comprises a processor 10, a memory 11, a bus 12. The processor 10 and the memory 11 are connected by a bus 12, the processor 10 being adapted to execute executable modules, such as computer programs, stored in the memory 11.

The processor 10 may be an integrated circuit chip with signal processing capabilities. In implementation, the steps of the smoke recognition, processing method may be performed by integrated logic circuitry of hardware or instructions in the form of software in the processor 10. The processor 10 may be a general-purpose processor, including a central processing unit (Central Processing Unit, CPU for short), a network processor (Network Processor, NP for short), etc.; but also digital signal processors (Digital Signal Processor, DSP for short), application specific integrated circuits (Application Specific Integrated Circuit, ASIC for short), field-programmable gate arrays (Field-Programmable Gate Array, FPGA for short) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components.

The memory 11 may comprise a high-speed random access memory (RAM: random Access Memory) and may also comprise a non-volatile memory (non-volatile memory), such as at least one disk memory.

Bus 12 may be a ISA (Industry Standard Architecture) bus, PCI (Peripheral Component Interconnect) bus, EISA (Extended Industry Standard Architecture) bus, or the like. Only one double-headed arrow is shown in fig. 2, but not only one bus 12 or one type of bus 12.

The memory 11 is used for storing programs, such as smoke recognition, programs for the processing means. The smoke recognition, processing means comprise at least one software functional module which may be stored in the memory 11 in the form of software or firmware (firmware) or cured in the Operating System (OS) of the electronic device. The processor 10, upon receiving the execution instructions, executes the program to implement the smoke recognition, processing method.

Possibly, the electronic device provided in the embodiment of the present application further includes a communication interface 13. The communication interface 13 is connected to the processor 10 via a bus.

It should be understood that the structure shown in fig. 2 is only a schematic structural diagram of a portion of an electronic device, which may also include more or fewer components than shown in fig. 2, or have a different configuration than shown in fig. 2. The components shown in fig. 2 may be implemented in hardware, software, or a combination thereof.

The smoke identification method provided in the embodiment of the present application may be, but is not limited to, applied to the electronic device shown in fig. 2, and referring to fig. 3, the smoke identification method includes: s101, S102, and S103 are specifically described below.

S101, acquiring difference point clouds between the first point cloud data and the second point cloud data.

The acquisition interval between the first point cloud data and the second point cloud data is smaller than a first preset duration.

Alternatively, the first point cloud data and the second point cloud data may be point cloud data obtained in adjacent acquisition periods, or may be set at intervals of a certain duration, or may be set according to a user requirement, or may be set based on an acquisition period length of the radar apparatus 200.

It will be appreciated that irregular and rapidly changing smoke is produced at the beginning of a fire, the major component of which is fine particles. When the light emitted by the laser radar strikes smoke, a corresponding echo signal is generated. Because smoke changes rapidly, there may be a large difference in echo signals, such as a range difference, between the first point cloud data and the second point cloud data, corresponding to the smoke portion. By acquiring the differential point cloud, it can be further determined whether the differential point cloud is a smoke area.

Alternatively, before S101, the management terminal 100 may also determine whether there is a differential point cloud between the first point cloud data and the second point cloud data. If so, S101 is executed, if not, the next detection period is waited to acquire new point cloud data, and then the judgment is carried out again.

S102, determining whether the differential point cloud is a smoke area. If yes, executing S103; if not, S101 is repeatedly executed, or is ended.

Alternatively, whether the differential point cloud is a smoke area may be determined based on preset conditions, which may be, but are not limited to, a first condition, a second condition, and a third condition. The first condition characterizes that the shape of the differential point cloud does not belong to a preset regular shape, the second condition characterizes that the ranging fluctuation value of the differential point cloud is larger than a first preset value, and the third condition characterizes that the reflection intensity fluctuation value of the differential point cloud is larger than a second preset value.

For example, when any one of the first condition, the second condition, and the third condition is satisfied, the smoke region is determined; or, when any one of the first condition, the second condition, and the third condition is not established, determining that the smoke area is not present; alternatively, when any two of the first condition, the second condition, and the third condition are satisfied, the smoke region is determined.

The laser radar is adopted as the smoke detection sensor, and the characteristics of large field of view, high resolution and high precision ranging and angle measurement of the laser radar are utilized to identify smoke, so that the defects of the prior art are overcome, the monitoring coverage area is large, the arrangement is simple, the fire disaster identification sensitivity is high, and the identification accuracy is high.

When the differential point cloud is identified as the smoke area, in order to further accurately distinguish the location of the fire, the embodiment of the present application further provides an alternative implementation, that is, executing S103.

When it is recognized that the differential point cloud is not a smoke region, S101 may be repeatedly performed after waiting for a preset time interval, or directly skipped.

And S103, identifying boundary information of the smoke area based on the difference point cloud.

Optionally, the boundary information of the smoke region includes boundary points of each axis of the smoke region in the radar coordinate system. The smoke area can be accurately positioned through the boundary information, and the effective completion of fire extinguishment is ensured.

On the basis of fig. 3, for the content in S102, a possible implementation manner is further provided in the embodiment of the present application, please refer to fig. 4, and S102 includes: s102-1 and S102-2 are specifically described below.

S102-1, determining whether the differential point cloud meets a preset first condition, a preset second condition and a preset third condition. If yes, executing S103; if not, S101 is repeatedly executed, or is ended.

The method comprises the steps that the shape of a first condition representation differential point cloud does not belong to a preset regular shape, the ranging fluctuation value of a second condition representation differential point cloud is larger than a first preset value, and the reflection intensity fluctuation value of a third condition representation differential point cloud is larger than a second preset value.

Alternatively, whether the first condition, the second condition, and the third condition are satisfied may be sequentially determined, or may be synchronously determined, and when any one of them is not satisfied, it is determined that the differential point cloud is not a smoke region.

S102-2, determining the differential point cloud as a smoke area.

On the basis of the smoke recognition method provided in the embodiment of the present application, the embodiment of the present application further provides a smoke processing method, which may be applied to, but not limited to, the electronic device shown in fig. 2, and referring to fig. 5, the smoke recognition method includes: s201, S202, and S203 are specifically described below.

S201, determining a target fire extinguishing area based on the first smoke area and the second smoke area.

The first smoke area and the second smoke area are two smoke areas identified in a second preset time based on the smoke identification method.

Optionally, the volume of the second smoke area is larger than the volume of the first smoke area, and the change trend of smoke can be determined by observing the first smoke area and the second smoke area, so that the target fire extinguishing area can be determined.

S202, controlling the fire extinguishing equipment to extinguish the fire in the target fire extinguishing area.

Alternatively, the target fire extinguishing area is extinguished by controlling the fire extinguishing apparatus 300 to spray the corresponding extinguishing agent.

Optionally, in order to further exclude potential safety hazards in the target area and guarantee safety of the target area, the embodiment of the present application further provides an optional implementation manner, where the fire protection system further includes an alarm device, and the alarm device is communicatively connected to the management terminal, and after S201 or S202, S203 may be executed.

S203, controlling the alarm equipment to alarm.

The alarm device can push alarm information to the user terminal or directly send out an audible and visual alarm signal.

On the basis of fig. 5, for the content in S201, the embodiment of the present application further provides an alternative implementation, please refer to fig. 6, S201 includes: s201-1 and S201-2 are specifically described below.

S201-1, determining a smoke spreading direction based on the boundary information of the first smoke region and the boundary information of the second smoke region.

Optionally, the identification position of the first smoke area is denoted as P1, the identification position of the second smoke area is denoted as P2, and the distance measurement deviation of the P2 position relative to the P1 position in the X-axis direction, the Y-axis direction and the Z-axis direction is compared, so that the distance of the smoke offset in three directions is determined, and the smoke trend is determined. Wherein XYZ is the triaxial in the laser radar coordinate system.

Alternatively, the dsdelta_ X, ddelta _y and dsdelta_z are obtained separately:

Ddelta_X＝P2.X-P1.X；

Ddelta_Y＝P2.Y-P1.Y；

Ddelta_Z＝P2.Z-P1.Z；

wherein (P1.X, P1.Y, P1.Z) characterizes the boundary extent of the first smoke region and (P2.X, P2.Y, P2.Z) characterizes the boundary extent of the second smoke region.

Specifically, when Ddelta_X is greater than 0, it indicates that the smoke moves toward the X-axis square relative to the P1 position, when Ddelta_X is less than 0, it indicates that the smoke moves toward the X-axis negative square relative to the P1 position, when Ddelta_Y is greater than 0, it indicates that the smoke moves toward the Y-axis square relative to the P1 position, when Ddelta_Y is less than 0, it indicates that the smoke moves toward the Y-axis negative square relative to the P1 position, when Ddelta_Z is greater than 0, it indicates that the smoke moves toward the Z-axis square relative to the P1 position, and when Ddelta_Z is less than 0.

It will be appreciated that after determining the direction of smoke spread, a subsequent area where potential hazards may exist may be further determined based on this.

Optionally, the expansion is performed in the smoke diffusing direction on the basis of the boundary information of the second smoke region, so that the target fire extinguishing region can be determined.

The whole scene is segmented into a plurality of regions of interest by the ROI function (region of interest) of the lidar. Different fire extinguishing agents are sprayed to different areas, so that the fire extinguishing agents are prevented from generating chemical reactions with other combustibles to generate secondary injury.

Optionally, the ROI function (Region of Interest region of interest) of the lidar belongs to a technical function of the lidar, namely the field of view of the lidar can be divided into a plurality of sub-fields of view, and radar data of each sub-field of view is identified. In practical application, the whole room can be divided into different subareas, and each subarea corresponds to one subarea field respectively. At least two sub-areas are responsible for extinguishing fire by different extinguishing agents or each different sub-area is responsible for extinguishing fire by a different extinguishing agent. In which sub-area a fire is occurring, a fire extinguishing agent of the corresponding kind is sprayed.
