Description

Technical Field

[0001] The present application relates to the technical field of fire monitoring and early warning, and in particular to a method and device for identifying and processing fire in plain forests. Background Art

[0002] In recent years, in order to prevent fires in forest plains or to extinguish fires in time when they occur, it is very important to monitor the fire conditions in forest plains. Usually, the forest plains are divided into areas, each area corresponds to a base station, and a monitoring server is set up on each base station to monitor the fire conditions in the area.

[0003] The fire conditions in the forest plains are monitored by the monitoring server set on the base station, so as to detect the fire in time and issue an alarm. Some areas divided into forest plains also include residential areas. When the monitoring server scans the area, the scanned data includes the data of the residential area, and the scanned data of the residential area is set as a shielded area. Since the judgment criteria for fire warning in forest areas are inconsistent with those in residential areas, when the fire warning judgment criteria in forest areas are used to judge residential areas, it is easy to cause misjudgment, resulting in frequent alarms from the monitoring server, increasing unnecessary labor costs, and therefore not processing the residential area. However, when a fire occurs in a residential area, the monitoring server set on the base station will set the residential area data as a shielded area when scanning the residential area, which will affect the forest land next to the residential area, and then cause a forest fire.

[0004] At present, there is an urgent need for a method and device for identifying and processing fire conditions in plain forests that can solve the above-mentioned problems. Summary of the invention

[0005] In response to the deficiencies in the relevant technologies, the present application provides a method and device for identifying and processing fire conditions in plain forests. When the method monitors the fire conditions in the forest plains through the monitoring system set up on the base station, the monitored shielded area data is analyzed. When a fire occurs in the shielded area, it can be discovered and processed in time, thereby avoiding affecting the forest land next to the residential area.

[0006] The first aspect of the present application provides a method for identifying and processing fire in plain forests, which is applied to a monitoring server, and the method also includes: obtaining image data of a monitoring area, the monitoring area includes a shielded area, the image data of the shielded area includes a first monitoring value and a second monitoring value, the shielded area includes 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; judging whether the first monitoring value is greater than or equal to a preset first monitoring threshold, and judging whether the second monitoring value is greater than or equal to a preset second monitoring threshold; when the first monitoring value is greater than or equal to the preset first monitoring threshold, or the second monitoring value is greater than or equal to the preset second monitoring threshold, confirming that a fire has occurred in the shielded area; sending an early warning message to a user device to prompt the staff to deal with the fire in the shielded area.

[0007] By adopting the above technical solution, image data of the current area is obtained, and it is determined whether the smoke concentration and temperature in the image data are greater than or equal to the preset threshold value. When the smoke concentration and temperature in the image data are greater than or equal to the preset threshold value, it is confirmed that the smoke concentration and temperature in the current area exceed the normal threshold value, and it is determined that a fire has occurred in the current area. A message is sent to the user device to prompt the relevant staff to deal with the area where the fire has occurred and to extinguish the fire in time when the fire occurs.

[0008] The second aspect of the present application provides a device for identifying and processing fire conditions in plain forests, the device being a monitoring server, the server comprising an acquisition unit, a judgment unit and a confirmation unit; the acquisition unit acquiring image data of a monitoring area, the monitoring area comprising a shielded area, the image data of the shielded area comprising a first monitoring value and a second monitoring value, the shielded area comprising a first monitoring area and a second monitoring area, the first monitoring area corresponding to the first monitoring value, the second monitoring area corresponding to the second monitoring value; the judgment unit judging whether the first monitoring value is greater than or equal to a preset first monitoring threshold, and judging whether the second monitoring value is greater than or equal to a preset second monitoring threshold; when the first monitoring value is greater than or equal to the preset first monitoring threshold, or the second monitoring value is greater than or equal to the preset second monitoring threshold, confirming that a fire has occurred in the shielded area; the confirmation unit sending an early warning message to a user device to prompt the staff to handle the fire in the shielded area.

[0009] By adopting the above technical solution, image data of the current area is obtained, and it is determined whether the smoke concentration and temperature in the image data are greater than or equal to the preset threshold value. When the smoke concentration and temperature in the image data are greater than or equal to the preset threshold value, it is confirmed that the smoke concentration and temperature in the current area exceed the normal threshold value, and it is determined that a fire has occurred in the current area. A message is sent to the user device to prompt the relevant staff to deal with the area where the fire has occurred and to extinguish the fire in time when the fire occurs.

[0010] Optionally, the first monitoring area is an outdoor camping area, the first monitoring value includes a first smoke concentration and a first temperature, and the preset first monitoring threshold includes a first preset smoke concentration threshold and a first preset temperature threshold; the judgment unit is the monitoring server that judges whether the first smoke concentration is greater than or equal to the first preset smoke concentration threshold, and whether the first temperature is greater than or equal to the first preset temperature threshold within a predetermined date; the predetermined date is a date when outdoor camping is prohibited; when the first smoke concentration is greater than or equal to the first preset smoke concentration threshold, and the first temperature is greater than or equal to the first preset temperature threshold, it is confirmed that a fire has occurred in the outdoor camping area.

[0011] By adopting the above technical solution, when judging the outdoor camping area in the shielded area, the opening time and closing time of the outdoor camping area are obtained, and the closed time of the outdoor camping area is set as the scheduled date. During the scheduled date, it is judged whether the image data of the outdoor camping area is greater than or equal to the first preset threshold. When it is confirmed that the image data of the outdoor camping area is greater than or equal to the first preset threshold, it is proved that a fire has occurred in the outdoor camping area, and the staff is prompted to handle it.

[0012] Optionally, the second monitoring area is a residential area, the second monitoring value includes a second smoke concentration and a second temperature, and the preset second monitoring threshold includes a second preset smoke concentration threshold and a second preset temperature threshold; the judgment unit is the monitoring server that judges whether the second smoke concentration is greater than or equal to the second preset smoke concentration threshold, and whether the second temperature is greater than or equal to the second preset temperature threshold within a preset time; the preset time is non-cooking time; when the second smoke concentration is greater than or equal to the second preset smoke concentration threshold, and the second temperature is greater than or equal to the second preset temperature threshold, it is confirmed that a fire has occurred in the residential area.

[0013] By adopting the above technical solution, when judging the residential area in the shielded area, the daily eating time of the residential area is obtained, and the time in the residential area other than the eating and living time is set as the preset time. During the preset time, it is judged whether the image data of the residential area is greater than or equal to the second preset threshold. When it is confirmed that the image data of the residential area is greater than or equal to the second preset threshold, it proves that a fire has occurred in the residential area, and the staff is prompted to deal with it.

[0014] Optionally, the receiving unit obtains image data of the non-shielded area; the non-shielded area includes a third monitoring value, and the third monitoring value includes a third smoke concentration and a third temperature; the historical image data includes historical smoke concentration and historical temperature; when the first monitoring value is less than a preset first monitoring threshold, or the second monitoring value is less than a preset second monitoring threshold, the judgment unit judges for the monitoring server whether the third smoke concentration is within the historical smoke concentration of the historical image data, and whether the third temperature is within the historical temperature of the historical image data; when neither the third smoke concentration nor the third temperature is within the historical image data, it is confirmed that a fire has occurred in the shielded area.

[0015] With the above technical solution, when the image data of the monitored area is greater than the preset threshold, it is determined that a fire has occurred in the area. When the staff arrives at the area, they find that no fire has occurred in the area. This fire alarm is a false fire, and the image data monitored this time is marked and stored in the historical database, and no alarm will be issued the next time it occurs. However, in order to avoid the situation where an alarm is missed but a fire actually occurs, the image data of the adjacent areas of the area are also obtained to determine whether the image data of the adjacent areas of the current area meets the historical image data. When it is determined that the image data of the adjacent areas of the current area does not meet the historical image data, it is confirmed that a fire has occurred in the current area and needs to be processed.

[0016] Optionally, the historical image data is constructed based on historical monitoring data of smoke density and temperature when no fire occurred.

[0017] By adopting the above technical solution, based on the monitored image data, the staff will confirm that it is a false fire after checking, and store the monitored image data for comparison when such a situation occurs again in the future, thereby reducing missed alarms.

[0018] Optionally, the server confirms that a fire has occurred in the monitoring area, determines a current alarm level based on the fire situation, and executes an alarm action corresponding to the alarm level based on the alarm level; wherein the alarm levels include a first level, a second level, and a third level; the first level is a serious fire, and an alarm instruction is sent to the fire station closest to the monitoring area; the second level is a moderate fire, and an alarm instruction is sent to the fire station within the monitoring area; the third level is a low fire, and it is determined whether the duration of the fire is greater than a preset time. When the duration of the fire is greater than the preset time, an alarm instruction is sent to the fire station within the monitoring area.

[0019] By adopting the above technical solution, the fire situation in the current area is judged, the alarm level is confirmed according to the fire situation, and the corresponding alarm action is performed according to the alarm level. When the fire situation is serious, the staff is arranged to respond quickly; when the fire situation is moderate, the staff in the area are arranged to respond accordingly; when the fire situation is low, it is judged whether the current fire time is greater than the preset time. If it is greater than the preset time, the staff is arranged to respond.

[0020] Optionally, the alarm level is determined based on the weather and wind direction of the monitoring area on the day; when the weather and wind direction of the monitoring area meet the first condition, the alarm level is confirmed to be the first level, and the first condition is a sunny day, level 9 to level 12; when the weather and wind direction of the monitoring area meet the second condition, the alarm level is confirmed to be the second level, and the second condition is cloudy or overcast, level 5 to level 8; when the weather and wind direction of the monitoring area meet the third condition, the alarm level is confirmed to be the third level, and the third condition is a rainy day, level 0 to level 4.

[0021] By adopting the above technical solution, the alarm level is determined according to the weather and wind direction of the day, and the number of alarms of the police officers can be adjusted according to the alarm level, thus saving the use of resources.

[0022] The third aspect of the present application provides an electronic device, which includes a processor, a memory, a user interface and a network interface, the memory is used to store instructions, the user interface and the network interface are used to communicate with other devices, and the processor is used to execute the instructions stored in the memory, so that an electronic device unit executes a method as described in any one of the first aspects of the present application.

[0023] A fourth aspect of the present application provides a computer-readable storage medium, which stores instructions. When the instructions are executed, the method described in any one of the first aspects of the present application is executed.

[0024] Compared with the related art, the beneficial effects of the present application are: when monitoring fires in forest plains, image data of the monitoring area is obtained according to the division of the area; it is determined whether the monitoring value in the image data of the shielded area is greater than or equal to the preset monitoring threshold, and when the monitoring value in the image data of the shielded area is greater than or equal to the preset monitoring threshold, it is confirmed that a fire has occurred in the shielded area, and an early warning message is sent to prompt the staff to deal with the fire in the shielded area; when monitoring the image data of the forest area, the load of the monitoring system is not increased, and the utilization rate of the monitoring system is improved; different alarm levels correspond according to the fire situation.

[0031] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0032] In the description of the embodiments of the present application, words such as "illustrative", "for example" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "illustrative", "for example" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "illustrative", "for example" or "for example" is intended to present related concepts in a specific way.

[0033] In addition, the terms "first", "second", etc. in the specification of the present application are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0034] The shielded area in this application refers to the monitoring area in the woodland plain, which includes residential areas, public areas and forest areas. The residential areas and public areas in this area are divided into shielded areas, and the forest areas are divided into non-shielded areas.

[0035] In recent years, in order to prevent fires in forest plains or to extinguish fires in time when fires occur, it is very important to monitor fires in forest plains. Usually, the area of ​​forest plains is divided, and a base station is set up for each area. Monitoring is set up on each base station to monitor the fire in the area. The fire in the forest plain is monitored by the monitoring set on the base station, so as to timely detect the fire and alarm. Some areas divided in the forest plains also include residential areas. When the monitoring scans the area, the scanned data includes the data of the residential area, and the scanned data of the residential area is set as a shielded area. Since the judgment criteria of the fire warning in the forest area are inconsistent with those in the residential area, when the fire warning judgment criteria in the forest area are used to judge the residential area, it is easy to cause misjudgment, resulting in frequent alarms on the monitoring server, increasing unnecessary labor costs, and therefore not processing the residential area. However, when a fire occurs in the residential area, the monitoring set on the base station will set the residential area data as a shielded area when scanning the residential area, which will affect the forest land next to the residential area, and then cause a forest fire. How to avoid this situation as much as possible is a problem that needs to be solved urgently.

[0036] The solution of this application is described in detail below.

[0037] The present application provides a method for identifying and processing forest fires in a plain, which is applied to a monitoring server. The present application takes a monitoring system for a forest plain as an example, where the monitoring server is a platform server for the management department of the forest plain or a third party providing services to the management department of the forest plain. Figure 1 is a flow chart of a method for identifying and processing fire conditions in plain forests provided in an embodiment of the present application; Figure 1 The method includes the following steps S101-S104.

[0038] Step S101: Acquire image data of a monitoring area, the monitoring area includes a shielded area, the image data of the shielded area includes a first monitoring value and a second monitoring value, the shielded area includes 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.

[0039] In the above steps, the monitoring server obtains the image data of the current monitoring area, and the monitoring area has a shielded area. In the fire monitoring system of plain forest, the divided area of ​​the forest plain also includes residential areas. When the monitoring scans the area, the scanned data includes the data of the residential area, and the scanned data of the residential area is set as the shielded area. The shielded area includes a first monitoring area and a second monitoring area. The first monitoring area corresponds to the first monitoring value in the image data of the shielded area, and the second monitoring area corresponds to the second monitoring value in the image data of the shielded area.

[0040] For example, when the monitoring system scans a fire in a woodland plain, the scanned image data is transmitted to the fire monitoring system in the woodland plain, and the first monitoring area and the second monitoring area of ​​the shielded area are scanned. The first monitoring area corresponds to a first monitoring value, and the first monitoring value includes smoke concentration and temperature. The monitored smoke concentration and temperature are compared with the preset smoke concentration and preset temperature in the system.

[0041] Step S102: Determine whether the first monitoring value is greater than or equal to a preset first monitoring threshold, and determine whether the second monitoring value is greater than or equal to a preset second monitoring threshold.

[0042] In the above steps, the first monitoring threshold is preset as the normal smoke concentration and temperature threshold of the first monitoring area, and the second monitoring threshold is preset as the normal smoke concentration and temperature threshold of the second monitoring area.

[0043] For example, the monitoring server obtains the first monitoring value of the first monitoring area of ​​the shielded area, and the smoke concentration of the first monitoring value is 23 mg / m3, and the temperature is 34 degrees Celsius. The preset smoke concentration of the preset first monitoring threshold is 25 mg / m3, and the preset temperature is 38 degrees Celsius. It is judged whether the first monitoring value is greater than or equal to the preset first monitoring value. The second monitoring value of the second monitoring area is obtained, and the smoke concentration of the second monitoring value is 26 mg / m3, and the temperature is 40 degrees Celsius. The preset smoke concentration of the preset second monitoring threshold is 26 mg / m3, and the preset temperature is 40 degrees Celsius. It is judged whether the second monitoring value is greater than or equal to the preset second monitoring value. The preset smoke concentration and temperature are mainly based on the actual situation.

[0044] Step S103: When the first monitoring value is greater than or equal to the preset first monitoring threshold, or the second monitoring value is greater than or equal to the preset second monitoring threshold, it is confirmed that a fire has occurred in the shielded area.

[0045] In the above steps, 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 confirmed that the image data of the first monitoring area is normal, and it is confirmed that a fire has occurred in the area. 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, it is confirmed that an abnormality has occurred in the image data of the second monitoring area, and it is confirmed that a fire has occurred in the area. 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, it is confirmed that an abnormality has occurred in the image data of the first monitoring area, and it is confirmed that a fire has occurred in the area. When the monitoring values ​​of the first monitoring area and the second monitoring area in the shielded area are respectively greater than or equal to the corresponding preset monitoring threshold, it is proved that a fire has occurred in the area.

[0046] For example, the smoke concentration of the first monitoring value is 23 mg / m3 and the temperature is 34 degrees Celsius. The preset smoke concentration of the preset first monitoring threshold is 25 mg / m3, the preset temperature is 38 degrees Celsius, and the first monitoring value is less than the preset first monitoring threshold. The smoke concentration of the second monitoring value is 26 mg / m3 and the temperature is 40 degrees Celsius. The preset smoke concentration of the preset second monitoring threshold is 26 mg / m3 and the preset temperature is 40 degrees Celsius, and the second monitoring value is greater than the preset second monitoring threshold. When the second monitoring value is greater than the preset second monitoring threshold, it is confirmed that a fire has occurred in the area. The preset smoke concentration and temperature are based on the actual situation.

[0047] Step S104: Sending warning information to the user equipment to prompt the staff to deal with the fire in the shielded area.

[0048] In the above steps, the user device can be an electronic device such as a mobile phone or a computer, etc., to remind the staff that a fire is currently occurring in the shielded area and the fire in the shielded area needs to be handled.

[0049] For example, when the smoke concentration in the first monitoring value of the first monitoring area is 27 mg / m3 and the temperature is 39 degrees Celsius, the preset smoke concentration of the preset first monitoring threshold is 25 mg / m3 and the preset temperature is 38 degrees Celsius, and the first monitoring value is greater than the preset first monitoring threshold, the monitoring system determines that a fire has occurred in the current area. Send an early warning message to the user device, which means that the temperature and smoke concentration in the current area have changed. The staff will check the early warning information of the user device and go to the area where the fire has occurred as soon as possible to deal with the fire.

[0050] Therefore, this manual provides three methods for judging the occurrence of a fire in the current area according to the above methods; the three methods for judging the occurrence of a fire are described below respectively.

[0051] In a possible embodiment, the first method for determining the fire condition includes steps S201 and S202. Figure 2 As shown, Figure 2 It is a flow chart of another method for identifying and processing fire conditions in plain forests provided in an embodiment of the present application.

[0052] Step S201: The monitoring server determines whether a first smoke concentration is greater than or equal to a first preset smoke concentration threshold value, and whether a first temperature is greater than or equal to a first preset temperature threshold value within a predetermined date.

[0053] In the above steps, when the monitoring server acquires the image data of the plain forest, since the shielded area also includes the outdoor camping area, etc., according to different areas in the shielded area, different areas have their own corresponding conditions for judging the fire situation. The opening time and closing time of the outdoor camping are obtained, the opening time and closing time of the outdoor camping area are recorded, the closing time of the outdoor camping area is set to a predetermined date, and the outdoor camping area in the shielded area is monitored within the predetermined date to determine whether the first smoke concentration of the outdoor camping area in the shielded area is greater than or equal to the first preset smoke concentration threshold, and whether the first temperature is greater than or equal to the first preset temperature threshold.

[0054] For example, the outdoor camping area is closed from May to September, and May to September are set as the scheduled dates. During the scheduled dates, the image data of the outdoor camping area is monitored to determine whether the first smoke concentration is greater than or equal to the first preset smoke concentration threshold, and whether the first temperature is greater than or equal to the first preset temperature threshold. The specific opening and closing times of outdoor camping are based on actual conditions and are not limited here.

[0055] Step S202: When the first smoke concentration is greater than or equal to a first preset smoke concentration threshold, and the first temperature is greater than or equal to a first preset temperature threshold, it is confirmed that a fire has occurred in the outdoor camping area.

[0056] In the above steps, the first preset smoke concentration threshold is data set for a normal smoke concentration threshold in an outdoor camping area, and the first preset temperature threshold is data set for a normal temperature threshold in an outdoor camping area.

[0057] For example, the outdoor camping area is closed from May to September, and May to September are set as the scheduled dates. When the first smoke concentration is 27 mg / m3 and the first temperature is 37 degrees Celsius, the first preset smoke concentration threshold is set to 25 mg / m3 and the first preset temperature threshold is 35 degrees Celsius. When the first smoke concentration is greater than the first preset smoke concentration threshold and the first temperature is greater than the first preset temperature threshold, it is confirmed that a fire has occurred in the outdoor camping area, and an early warning message is sent to the user device to prompt the staff to deal with the fire in the outdoor camping area.

[0058] In a possible embodiment, the second method for determining the fire condition includes steps S301 and S302. Figure 3 As shown, Figure 3 It is a flow chart of another method for identifying and processing fire conditions in plain forests provided in an embodiment of the present application.

[0059] Step S301: The monitoring server determines whether the second smoke concentration is greater than or equal to the second preset smoke concentration threshold value, and whether the second temperature is greater than or equal to the second preset temperature threshold value within a preset time.

[0060] In the above steps, when the monitoring server acquires the image data of the plain forest, since the shielded area includes residential areas, etc., different areas in the shielded area have their own corresponding conditions for judging the fire situation. The time when the residential area usually cooks is recorded, and the data of the residential area not usually cooking is set as a preset time. The residential area in the shielded area is monitored within the preset time to determine whether the second smoke concentration of the residential area in the shielded area is greater than or equal to the second preset smoke concentration threshold, and whether the second temperature is greater than or equal to the second preset temperature threshold.

[0061] For example, the usual cooking time in residential areas is from 6 to 8 in the morning, from 11 to 1 at noon, and from 6 to 8 in the evening, and other time periods are set as preset time. The image data of the residential area is monitored within the preset time to determine whether the second smoke concentration currently monitored is greater than or equal to the preset second smoke concentration threshold, and whether the second temperature is greater than or equal to the preset second temperature threshold. The cooking time in the residential area is based on the actual situation and is not limited here.

[0062] Step S302: When the second smoke concentration is greater than or equal to the second preset smoke concentration threshold, and the second temperature is greater than or equal to the second preset temperature threshold, it is confirmed that a fire has occurred in the residential area.

[0063] In the above steps, the second preset smoke density threshold is a threshold value set according to the normal smoke density threshold value in the residential area. The second preset temperature is a data set according to the normal temperature threshold value in the residential area.

[0064] For example, the preset time is a time period when the residential area does not usually cook. When the second smoke concentration is 29 mg / m3 and the second temperature is 39 degrees Celsius, the second preset smoke concentration threshold is set to 27 mg / m3 and the second preset temperature threshold is 37 degrees Celsius. When the second smoke concentration threshold is greater than the second preset smoke concentration threshold and the second temperature is greater than the second preset temperature threshold, it is confirmed that a fire has occurred in the residential area, and an early warning message is sent to the user device to prompt the staff to deal with the fire in the residential area.

[0065] In a possible embodiment, the third method for determining the fire condition includes steps S401 and S402. Figure 4 As shown, Figure 4 It is a flow chart of another method for identifying and processing fire conditions in plain forests provided in an embodiment of the present application.

[0066] Step 401: When the first monitoring value is less than the preset first monitoring threshold, or the second monitoring value is less than the preset second monitoring threshold, the monitoring server determines whether the third smoke concentration is within the historical smoke concentration of the historical image data, and whether the third temperature is within the historical temperature of the historical image data.

[0067] In the above steps, the historical image data is constructed based on the historical monitoring data of smoke concentration and temperature when no fire occurs.

[0068] When the monitoring server obtains the first monitoring value of the first monitoring area, it also obtains the third monitoring value of the third monitoring area adjacent to the first monitoring area. When it is confirmed that the first monitoring value is less than the preset first monitoring threshold, the monitoring value of the adjacent area is recorded. The image data of previous fires is retrieved, and after the staff went to the scene to check, it was found that the fire in the current area was a false fire. The image data of the area adjacent to the current area is obtained, and the image data of the adjacent area is associated with the image data of the current area, and the associated data is recorded in the historical image data. When the same image data as the false fire appears again in the future, the image data of the adjacent area can be obtained, and combined with the image data of the adjacent area to determine whether a fire has occurred in the current shielded area.

[0069] For example, in the first monitoring value of the first monitoring area, the first smoke concentration is 23 mg / m3, the first temperature is 34 degrees Celsius, and in the preset first monitoring threshold, the preset first smoke concentration is 25 mg / m3, and the preset first temperature is 35 degrees Celsius. For the third monitoring area adjacent to the first monitoring area, the monitoring server monitors whether the third smoke concentration of the third monitoring area is within the historical smoke concentration of the historical image data, and whether the third temperature is within the historical temperature of the historical image data.

[0070] Step 402: When the third smoke density and the third temperature are not in the historical image data, it is confirmed that a fire has occurred in the shielded area.

[0071] In the above steps, the third smoke density and the third temperature are image data of a third monitoring area adjacent to the first monitoring area.

[0072] For example, in the first monitoring value of the first monitoring area, the first smoke concentration is 23 mg / m3, and the first temperature is 34 degrees Celsius. In the preset first monitoring threshold, the preset first smoke concentration is 25 mg / m3, and the preset first temperature is 35 degrees Celsius. The first monitoring value is less than the preset first monitoring threshold. In the third monitoring area adjacent to the first monitoring area, the current third smoke concentration in the third monitoring area is 26 mg / m3, and the third temperature is 37 degrees Celsius. In the historical image data, the third smoke concentration in the third monitoring area is 20 mg / m3, and the third temperature is 32 degrees Celsius. The third smoke concentration and the third temperature of the current third monitoring area are not in the historical image data, so it is judged that a fire has occurred in the current shielded area.

[0073] In a possible embodiment, the monitoring server confirms that a fire has occurred in the monitoring area, and determines the current alarm level according to the fire situation; according to the alarm level, the alarm action corresponding to the alarm level is executed; wherein the alarm levels include the first level, the second level and the third level; the first level is a serious fire, and an alarm instruction is sent to the fire station closest to the monitoring area; the second level is a moderate fire, and an alarm instruction is sent to the fire station in the monitoring area; the third level is a low fire, and it is determined whether the duration of the fire is greater than the preset time. When the duration of the fire is greater than the preset time, an alarm instruction is sent to the fire station in the monitoring area.

[0074] In the above embodiment, the preset time is based on the historical occurrence of fires, and the fire in the area is handled within a certain period of time.

[0075] In a possible embodiment, the alarm level is determined based on the weather and wind direction of the monitoring area on the day; when the weather and wind direction of the monitoring area meet the first condition, the alarm level is confirmed to be the first level, the first condition is a sunny day, level 9 to level 12; when the weather and wind direction of the monitoring area meet the second condition, the alarm level is confirmed to be the second level, the second condition is cloudy or overcast, level 5 to level 8; when the weather and wind direction of the monitoring area meet the third condition, the alarm level is confirmed to be the third level, the third condition is a rainy day, level 0 to level 4.
