In recent years, it is important to monitor the forest land in order to prevent the occurrence of a fire in the forest land or to extinguish a fire in time when a fire occurs. The areas of the forest land plain are generally divided, each area is correspondingly provided with a base station, and each base station is provided with a monitor to monitor the fire of the area. The fire condition of the woodland plain is monitored through the monitoring arranged on the base station, so that the fire condition can be found in time to alarm. The method comprises the steps that the regions divided by the forest land plain also comprise residential areas, when the regions are monitored to be scanned, the scanned data comprise the data of the residential areas, and the scanned data of the residential areas are set as shielding areas. Because the judgment standard of the fire early warning of the forest region is inconsistent with the residential area, when the residential area is judged by adopting the fire early warning judgment standard of the forest region, misjudgment is easily caused, so that the monitoring server frequently gives an alarm, unnecessary labor cost is increased, and the residential area is not processed. However, when a fire occurs in a residential area, since residential area data is set to a shielded area by monitoring and scanning the residential area set on the base station, forest lands beside the residential area are affected, and then forest land fire is caused. How to avoid the situation as much as possible is a problem which needs to be solved urgently at present.
The following specifically describes the embodiments of the present application.
The embodiment of the application provides a plain forest fire identification processing method which is applied to a monitoring server. The monitoring system of the forest land plain is taken as an example for explanation, and at the moment, the monitoring server is a platform server for providing services for a management department of the forest land plain or a third party for the management department of the forest land plain. Fig. 1 is a schematic flowchart of a fire identification processing method for a plain forest land according to an embodiment of the present application; referring to fig. 1, the method includes the following steps S101 to S104.
Step S101: the method comprises the steps of obtaining image data of a monitoring area, wherein the monitoring area comprises a shielding area, the image data of the shielding area comprises a first monitoring value and a second monitoring value, the shielding area comprises a first monitoring area and a second monitoring area, the first monitoring area corresponds to the first monitoring value, and the second monitoring area corresponds to the second monitoring value.
In the above steps, the monitoring server obtains the image data of the current monitoring area, and the monitoring area has a shielding area. In the fire monitoring system of the plain woodland, the partitioned areas of the woodland plain further comprise residential areas, when the areas are scanned, the scanned data comprise the data of the residential areas, and the scanned data of the residential areas are set as shielding areas. The shielding area comprises a first monitoring area and a second monitoring area, the first monitoring area corresponds to a first monitoring value in the image data of the shielding area, and the second monitoring area corresponds to a second monitoring value in the image data of the shielding area.
For example, when the monitoring system scans the fire of the forest land plain, the scanned image data is transmitted to the fire monitoring system of the forest land plain, a first monitoring area and a second monitoring area of the shielding area are scanned, the first monitoring area corresponds to a first monitoring value, the first monitoring value comprises smoke concentration and temperature, and the monitored smoke concentration and temperature are compared with preset smoke concentration and preset temperature in the system.
Step S102: and judging whether the first monitoring value is greater than or equal to a preset first monitoring threshold value or not, and judging whether the second monitoring value is greater than or equal to a preset second monitoring threshold value or not.
In the above step, the first monitoring threshold is preset as the normal smoke concentration and temperature of the first monitoring area are thresholds. The preset second monitoring threshold is the threshold of normal smoke concentration and temperature in the second monitoring area.
For example, the monitoring server obtains a first monitoring value of a first monitoring area of the shielding area, where the smoke concentration of the first monitoring value is 23 mg/cubic meter, and the temperature is 34 ℃. And presetting the preset smoke concentration of 25 mg/cubic meter and the preset temperature of 38 ℃ according to the preset first monitoring threshold value, and judging whether the first monitoring value is greater than or equal to the preset first monitoring value. And acquiring a second monitoring value of a second monitoring area, wherein the smoke concentration of the second monitoring value is 26 mg/cubic meter, and the temperature is 40 ℃. Presetting a preset smoke concentration of 26 mg/cubic meter set by a second monitoring threshold, and judging whether the second monitoring value is greater than or equal to a preset second monitoring value or not when the preset temperature is 40 ℃. The preset smoke concentration and temperature are based on actual conditions.
Step S103: and when the first monitoring value is greater than or equal to a preset first monitoring threshold value, or the second monitoring value is greater than or equal to a preset second monitoring threshold value, the shielded area is confirmed to be in a fire situation.
In the above step, when the smoke concentration in the first monitoring value is less than the preset smoke concentration and the temperature in the first monitoring value is less than the preset temperature, it is determined that the image data of the first monitoring area is normal, and it is determined that a fire occurs in the area. And when the smoke concentration in the second monitoring value is greater than the preset smoke concentration and the temperature in the second monitoring value is greater than the preset temperature, determining that the image data of the second monitoring area is abnormal, and determining that the area generates a fire. And when the smoke concentration in the first monitoring value is equal to the preset smoke concentration and the temperature in the first monitoring value is equal to the preset temperature, determining that the image data of the first monitoring area is abnormal, and determining that the area generates a fire. And when the monitoring values of the first monitoring area and the second monitoring area in the shielding area are respectively greater than or equal to the corresponding preset monitoring threshold value, the area is proved to have a fire condition.
For example, the smoke concentration of the first monitored value is 23 mg/m and the temperature is 34 degrees celsius. The preset smoke concentration set by the preset first monitoring threshold is 25 mg/cubic meter, the preset temperature is 38 ℃, and the first monitoring value is smaller than the preset first monitoring threshold. The second monitored value has a smoke concentration of 26 mg/cubic meter and a temperature of 40 degrees celsius. The preset smoke concentration set by the preset second monitoring threshold is 26 mg/cubic meter, the preset temperature is 40 ℃, and the second monitoring value is larger than the preset second monitoring threshold. And when the second monitoring value is larger than a preset second monitoring threshold value, the fire condition in the area is confirmed. The preset smoke concentration and temperature are mainly based on actual conditions.
Step S104: and sending early warning information to the user equipment to prompt staff to process the fire condition of the shielded area.
In the above steps, the user equipment may be an electronic device such as a mobile phone or a computer. The fire condition in the shielding area needs to be processed in order to prompt workers that the fire condition is generated in the shielding area currently.
For example, when the smoke concentration in the first monitored value of the first monitored area is 27 mg/m, the temperature is 39 degrees celsius. The preset smoke concentration set by the preset first monitoring threshold value is 25 mg/cubic meter, the preset temperature is 38 ℃, the first monitoring value is larger than the preset first monitoring threshold value, and the monitoring system judges that the fire happens in the area currently. And sending early warning information to the user equipment, wherein the early warning information indicates that the temperature and the smoke concentration in the current area change, and the staff goes to the area where the fire happens as soon as possible by checking the early warning information of the user equipment to process the fire.
Therefore, the specification aims at the above-mentioned way of judging the fire occurrence in the current area, and there are three ways of judging the fire; the three ways of determining the fire will be described below.
In one possible embodiment, the first way of determining the fire comprises steps S201 to S202. That is, as shown in fig. 2, fig. 2 is a schematic flowchart of another method for identifying and processing fire in a plain forest land according to an embodiment of the present application.
Step S201: the monitoring server judges whether the first smoke concentration is greater than or equal to a first preset smoke concentration threshold value or not within a preset date and whether the first temperature is greater than or equal to a first preset temperature threshold value or not.
In the above steps, when the monitoring server acquires the image data of the plain forest land, because the shielded area further includes an outdoor camping area and the like, according to different areas in the shielded area, different areas have respective conditions for judging the fire situation. The method comprises the steps of obtaining the open time and the close time of outdoor camping, recording the open time and the close time of an outdoor camping region, setting the close time of the outdoor camping region to be a preset date, monitoring the outdoor camping region in a shielding region in the preset date, judging whether the first smoke concentration of the outdoor camping region in the shielding region is larger than or equal to a first preset smoke concentration threshold value or not, and judging whether the first temperature is larger than or equal to a first preset temperature threshold value or not.
For example, the closing time of the outdoor camping area is 5 months to 9 months, the 5 months to 9 months are set as the predetermined date, the image data of the outdoor camping area is monitored within the predetermined date, and whether the first smoke concentration is greater than or equal to the first preset smoke concentration threshold value and the first temperature is greater than or equal to the first preset temperature threshold value is judged. The specific opening time and closing time of the outdoor camping are based on actual conditions, and are not limited here.
Step S202: and when the first smoke concentration is greater than or equal to a first preset smoke concentration threshold value and the first temperature is greater than or equal to a first preset temperature threshold value, the outdoor camping region is confirmed to have a fire.
In the above step, the first preset smoke concentration threshold is data set by a normal smoke concentration threshold of the outdoor camping area, and the first preset temperature threshold is data set by a normal temperature threshold of the outdoor camping area.
For example, the outdoor camping district is closed for 5 to 9 months, the predetermined date is set for 5 to 9 months, and when the first smoke concentration is 27 mg/m, the first temperature is 37 ℃. The first preset smoke concentration threshold is set at 25 mg/cubic meter and the first preset temperature threshold is 35 degrees celsius. First smog concentration is greater than first preset smog concentration threshold value, and first temperature is greater than first preset temperature threshold value, confirms that this outdoor camping district takes place the condition of a fire, sends early warning information to user equipment to the suggestion staff handles the condition of a fire in outdoor camping district.
In one possible embodiment, the second way of determining a fire comprises steps S301-S302. As shown in fig. 3, fig. 3 is a schematic flow chart of another method for recognizing and processing fire in a plain forest land according to an embodiment of the present application.
Step S301: and the monitoring server judges whether the second smoke concentration is greater than or equal to a second preset smoke concentration threshold value or not within preset time, and whether the second temperature is greater than or equal to a second preset temperature threshold value or not.
In the above steps, when the monitoring server acquires the image data of the plain forest land, because the shielded area includes residential areas and the like, different areas have respective conditions for judging the fire according to different areas in the shielded area. The method comprises the steps of recording the time of cooking in the residential area at ordinary times, setting the data of not cooking in the residential area at ordinary times as preset time, monitoring the residential area in the shielding area within the preset time, and judging whether the second smoke concentration of the residential area in the shielding area is greater than or equal to a second preset smoke concentration threshold value or not and whether the second temperature is greater than or equal to a second preset temperature threshold value or not.
For example, the ordinary cooking time in the residential area is 6 to 8 am, 11 to 1 am and 6 to 8 pm, and the other time periods are set as the preset time. And monitoring the image data of the residential area within a preset time, and judging whether the currently monitored second smoke concentration is greater than or equal to a preset second smoke concentration threshold value or not and whether the second temperature is greater than or equal to a preset second temperature threshold value or not. The cooking time in the residential area is mainly based on the actual situation, and is not limited here.
Step S302: and when the second smoke concentration is greater than or equal to a second preset smoke concentration threshold value and the second temperature is greater than or equal to a second preset temperature threshold value, determining that the fire occurs in the residential area.
In the above step, the second preset smoke density threshold is a threshold set according to a normal smoke density threshold of a residential area. The second preset temperature is data set according to a normal temperature threshold value of the residential area.
For example, the preset time is a time period when the resident is not cooking at ordinary times, and when the second smoke concentration is 29 mg/cubic meter, the second temperature is 39 ℃. The second preset smoke concentration threshold is set at 27 mg/m and the second preset temperature threshold is 37 degrees celsius. And the second smoke concentration threshold value is greater than a second preset smoke concentration threshold value, and the second temperature is greater than a second preset temperature threshold value, so that the fire condition of the residential area is confirmed, and early warning information is sent to the user equipment to prompt a worker to process the fire condition of the residential area.
In one possible embodiment, the third way of determining the fire comprises steps S401-S402. That is, as shown in fig. 4, fig. 4 is a schematic flowchart of another plain forest fire identification processing method provided in the embodiment of the present application.
Step 401: and when the first monitoring value is smaller than a preset first monitoring threshold value or the second monitoring value is smaller than a preset second monitoring threshold value, the monitoring server judges whether the third smoke concentration is in the historical smoke concentration of the historical image data or not and whether the third temperature is in the historical temperature of the historical image data or not.
In the above step, the historical image data is image data constructed by monitoring the smoke concentration and temperature data according to the history of non-occurrence of fire.
And when the monitoring server acquires the first monitoring value of the first monitoring area, the monitoring server acquires a third monitoring value of a third monitoring area adjacent to the first monitoring area. And recording the monitoring values of the adjacent areas when the first monitoring value is confirmed to be smaller than a preset first monitoring threshold value. And calling the image data of the past fire, and checking the image data by a worker on site to find that the fire occurring in the current area is false. Acquiring image data of an adjacent area of the current area, associating the image data of the adjacent area with the image data of the current area, and recording the associated image data in historical image data. And when the image data same as the false fire appears later, the image data of the adjacent area can be acquired, and whether the fire occurs in the current shielding area or not is judged by combining the image data of the adjacent area.
