The method comprises the following steps (201-203):
The data acquisition node may acquire the environmental state data in the target area at regular intervals, and may also continuously acquire the environmental state data in the target area in real time, which is not limited in the embodiment of the present application.
The environmental state data refers to data reflecting an environmental state in the target area, and the environmental state data includes air temperature, air humidity, an environmental image, an environmental video, and the like. Illustratively, when the hardware device corresponding to the data acquisition node includes an infrared sensor, the environmental state data acquired by the infrared sensor is air temperature information in the target area. Illustratively, when the hardware device corresponding to the data acquisition node includes a camera, the environmental state data acquired by the camera is an environmental image or an environmental video in the target area. In practical application, in order to improve the stability of the fire early warning system and collect various environmental state data, the hardware device corresponding to the data collection node may include an infrared sensor or a camera, that is, the environmental state data acquired by the data collection node may include an air temperature or an environmental image or an environmental video.
The blockchain system may include a plurality of blockchains, and data of each node may be stored in one same blockchain or different blockchains. Alternatively, if the data of each node is stored in different block chains, one node corresponds to one block chain. The embodiments of the present application are described only by storing data of each node in one same block chain, and other embodiments will be easily conceived by those skilled in the art after considering the solution of the present application, but all fall within the scope of the present application.
Optionally, the storing, by the data collection node, the environmental state data into the blockchain includes: the data acquisition node sends the environment state data to the n block chain nodes; after a target block chain node in the n block chain nodes acquires the permission to add a block in the block chain, adding a first block in the block chain, wherein the first block comprises environment state data; the target blockchain node sends a blockadding indication to other blockchain nodes in the blockchain system, wherein the blockadding indication is used for indicating the other blockchain nodes to add the first block in the blockchain.
And after the data acquisition node acquires the environmental state data, the environmental state data is sent to the n block chain link points in the block chain system. The n block chain link points in the block chain system upload the data received by the node to the block chain at regular intervals, the data of each node in the time form the latest block in the corresponding block chain, the block chain link point corresponding to the block chain which forms the latest block firstly is the target block chain node, and the target block chain node obtains the permission of adding the block in the block chain. And when the target block chain node acquires the permission of adding the block, adding the latest block in the block chain, namely the first block, and sending a block adding instruction to the chain nodes of other blocks. After receiving the block addition indication, the other block link nodes first agree on the data in the first block, i.e. the first block is allowed to be written into the corresponding block chain, and after agreeing, the other block link nodes add the first block in the corresponding block chain. The embodiment of the present application does not limit the specific form of achieving the consensus, that is, the consensus may be that all nodes in the blockchain system agree to add the data to the blockchain, or that most nodes in the blockchain system agree to add the data to the blockchain, for example, more than 51% of the nodes agree to add the data to the blockchain.
Optionally, after each blockchain node in the blockchain system obtains data in a target block in the blockchain, the data is compared with existing data of the blockchain node, the same part is removed, and then the data is stored in the blockchain corresponding to the blockchain node according to a certain classification standard. For example, each blockchain node may use a category of a node as a classification standard when data is stored, or use a category of a hardware device corresponding to the node as a classification standard when data is stored, which is not limited in the embodiment of the present application. For example, as shown in fig. 3, when each blockchain node takes the category of the hardware device corresponding to the node as a classification criterion when storing data, assuming that the hardware device corresponding to the data acquisition node includes an infrared sensor and a camera, the stored data 300 in each blockchain node includes infrared sensor data 301 and camera data 302, that is, the infrared sensor data 301 and the camera data 302 are stored separately. For example, in order to conveniently distinguish data of each hardware device, each node respectively uploads the data of the hardware device according to the type of the hardware device corresponding to the node when uploading the data to the block chain, and the first block in the block chain also stores the data of the hardware device according to the type of the hardware device corresponding to the node.
After the processing node acquires the data in the block chain, the data is analyzed and processed, so that the purpose of finding whether a fire occurs in the target area is achieved. The specific analysis processing mode of the processing node on the data may be determined according to the content of the environmental status data included in the data, which is not limited in the embodiment of the present application. Illustratively, when the hardware device corresponding to the data acquisition node comprises an infrared sensor, the environmental state data acquired by the data acquisition node comprises an air temperature, and after the processing node acquires the data comprising the environmental state data from the target block, whether a fire occurs in the target area is determined according to the air temperature. Illustratively, when the hardware device corresponding to the data acquisition node comprises a camera, the environmental state data acquired by the data acquisition node comprises a video image, and after the processing node acquires the data comprising the environmental state data from the target block, whether a fire occurs in the target area is determined according to whether an area in the video image is on fire. Optionally, when the environmental state data collected by the data collection node is stored in the first block in the block chain, the processing node obtains the data in the first block in the block chain.
In a possible implementation manner, the data includes environment state data corresponding to k positions in the target area, where k is a positive integer; the processing node determines whether a fire occurs in the target area according to the data, and the method comprises the following steps: the processing node detects whether the data has abnormal conditions, wherein the abnormal conditions comprise at least one of the following conditions: the target area has at least one position corresponding to the environmental state data which meets the preset condition and at least one position corresponding to the environmental state data which is missing; and if the data has abnormal conditions, the processing node determines that fire occurs in the target area.
The embodiment of the present application does not limit the specific content of the preset condition. For example, when the environmental status data includes an air temperature, the preset condition is a temperature of the flame, and when the processing node detects that the air temperature corresponding to a certain position reaches the temperature of the flame, it is determined that the environmental status data meets the preset condition. For example, when the environmental status data includes a video image, the preset condition is that a flame is displayed in the video image, and when the processing node detects that a flame is displayed in the video image at a certain position, it is determined that the environmental status data meets the preset condition.
The fact that the environmental state data corresponding to a certain position is missing means that no environmental state data are collected at the position. For example, if there are 3 locations in the target area, which are denoted as location 1, location 2, and location 3, and it is assumed that the processing node receives the environmental status data corresponding to location 1 and location 3, but does not receive the environmental status data corresponding to location 2, it is determined that there is an abnormal situation at location 2, for example, the hardware device corresponding to location 2 is burned due to a fire.
The detailed information of the fire includes the location of the fire, the direction of the spread of the fire, the size of the fire, etc., which is not limited in the embodiments of the present application. And after determining the detail information of the fire, the processing node sends the detail information of the fire to the n block chain link points in the block chain system. The n block chain link points in the block chain system upload the data received by the node to the block chain at regular intervals, the data of each node in the time form the latest block in the corresponding block chain, the block chain link point corresponding to the block chain which forms the latest block firstly is the target block chain node, and the target block chain node obtains the permission of adding the block in the block chain. And after the target block chain node acquires the permission of adding the block, adding the latest block in the block chain, namely a second block, and sending a block adding instruction to other block chain nodes. After receiving the block addition indication, the other block link nodes first agree on the data in the second block, i.e. the second block is allowed to be written into the corresponding block chain, and after agreeing, the other block link nodes add the second block into the corresponding block chain.
And step 203, the alarm node sends out alarm information after acquiring the detail information of the fire from the blockchain.
The alarm information is used for indicating the occurrence of fire in the target area so as to remind people in the target area to evacuate as soon as possible. Optionally, the warning information includes an escape route and a danger avoidance notification. Optionally, when the detail information of the fire analyzed by the processing node is stored in a second block in the block chain, the processing node acquires data in the second block in the block chain.
In summary, according to the technical scheme provided by the embodiment of the application, the block chain system is added in the fire warning system, the data acquisition node acquires data and stores the data into the block chain, the processing node acquires the data from the block chain and analyzes and processes the data, and the warning node acquires the processing result of the processing node from the block chain and sends out warning information, so that the purposes of timely discovering the fire and processing the fire are achieved. In addition, in the embodiment of the application, data of each node is uploaded to the blockchain system, and each node also acquires data of other nodes from the blockchain system.

The target location refers to a location where a fire occurs. The embodiment of the application does not limit the specific number of the target positions, optionally, one fire condition may correspond to one target position or a plurality of target positions, and when one fire condition corresponds to a plurality of target positions, the number of the target positions is determined according to details of the fire condition, for example, when an area where the fire condition occurs is large, 6 target positions are selected; when the area where the fire occurs is small, 2 target positions are selected.
The location information includes at least one target location. Optionally, the location information further includes a current location of the hardware device corresponding to the monitoring node. Optionally, the position information further includes preset tracks of hardware devices corresponding to the monitoring nodes passing through each target position.

And the hardware equipment corresponding to the monitoring node performs image shooting according to the position information 400, so that the monitoring image at the target position can be obtained.

After receiving the block addition instruction, the other block link nodes firstly agree on the data in the third block, that is, the third block is allowed to be written into the corresponding block chain, and after agreeing, the other block link nodes add the third block in the corresponding block chains.
Optionally, in order to further improve stability and safety of the fire warning system, the processing node sends the location information to the monitoring node, including: the processing node stores the position information into a block chain; the monitoring node obtains the position information from the block chain.
