Abstract
Description
Technical Field
[0001] The present invention relates to the field of remote monitoring technology, and in particular to a smart fire remote monitoring system. Background Art
[0002] In recent years, high temperature weather has become more and more frequent. Parks sometimes experience spontaneous combustion due to a large number of fallen leaves and hot and dry air. Due to the large flow of people in parks, some people may ignore park rules, bring fire sources without authorization and abandon them at will after use, making the park prone to fires. Parks are often large in scale, and it is difficult to detect these fire hazards in time by manual labor alone. Therefore, remote monitoring of fire protection in parks is very necessary.
[0003] Prior art, such as the invention patent application with announcement number: CN113299029B, discloses a smart fire remote monitoring system, which includes: the monitoring center dispatches firefighters and firefighting vehicles according to the fire scene situation transmitted by the remote alarm system, and formulates the route of the fire truck according to the road conditions, and the monitoring center transmits the route of the fire truck to the traffic management system; the traffic management system controls the status of traffic lights at each intersection on the route of the fire truck, ensuring that the fire truck always moves at a speed greater than or equal to 40km / h. This invention provides a basis for rapid deployment of emergency firefighting work through the cooperation of firefighting and traffic control, reducing property losses and loss of life.
[0004] The prior art, such as the invention patent application with announcement number: CN111800489B, discloses a smart fire remote monitoring system, which includes: an Internet of Things monitoring and management platform, which is used to receive fire data uploaded by several monitoring centers and display the real-time fire status of the fire area; a hidden danger analysis module, which is used to analyze the fire data of the Internet of Things monitoring and management platform and divide the fire protection level of the fire area; a monitoring center, a fire protection system distributed in each building, which is used to receive monitoring data and alarm data from the monitoring and alarm subsystem; a monitoring and alarm subsystem, which is used to collect and send fire monitoring data and alarm information to the monitoring center in real time; and a fire extinguishing module. This invention has the effect of improving the information interaction between the monitoring centers in the fire area.
[0005] From the above scheme, it can be seen that the current intelligent fire remote monitoring system lacks certain attention to the analysis of fallen leaves around high-temperature objects in various areas of the park. When abandoned high-temperature objects appear in the park, traditional analysis methods often only focus on air temperature and humidity. Whether high-temperature objects can cause fires, in addition to air temperature and humidity, the surface area and thickness of fallen leaves are also important factors. The grass itself continues to absorb underground moisture, so it is easy to remain moist and difficult to ignite, while the fallen leaves themselves are relatively dry and easy to ignite. When the fallen leaves have a large surface area and high thickness, they can still be ignited in some low-temperature and relatively humid air conditions, thereby causing a fire and reducing the safety of the park. At the same time, there is a lack of attention to the impact of fire sources on surrounding areas. The park itself is well ventilated. When a fire source appears, it is easy for sparks to be blown to the surrounding areas due to strong winds, causing fires in the surrounding areas and endangering the safety of pedestrians in the park. Summary of the invention
[0006] The purpose of the present invention is to provide a smart fire remote monitoring system that solves the problems existing in the background technology.

[0010] The fire sprinkler processing module is used to determine whether there are people around the fire sprinklers in the fire hazard areas and the fire hazard affected areas of the park before carrying out fire sprinkler operations.

[0030] Based on the geographical scope of each area to which the park belongs, the geographical scope of each normal area to which the park belongs is extracted.
[0031] If the geographical scope of a normal area belonging to a park contacts the high temperature affected range of a high temperature object in a high temperature area belonging to the park, the normal area is marked as a high temperature affected area, thereby screening the high temperature affected areas belonging to the park.

If the relative geographical location distance between the fire sprinklers in a fire hazard area of the park and the nearest pedestrian is less than the safe fire fighting distance, it is judged that there are people around the fire sprinklers in the fire hazard area of the park. Otherwise, it is judged that there are no people around the fire sprinklers in the fire hazard area of the park, thereby judging whether there are people around the fire sprinklers in each fire hazard area of the park.

[0046] (4) The fire sprinkler treatment module of the present invention locates fires in various fire hazard areas of the park and humidifies the air in various fire hazard areas of the park and in areas affected by fire hazards. Since the park is often large in size, continuous humidification is often extremely wasteful of water resources. Therefore, humidification is only performed in time when fire hazards occur or are affected by fire hazards. While saving water resources, the possibility of fire is reduced, thereby ensuring the safety of the park. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the module takes into account the wind direction and wind speed of the park itself, and analyzes the harm of sparks in each high-temperature area of the park to the surrounding areas due to wind, so that fire hazards in the surrounding areas of each high-temperature area of the park can be discovered in time to ensure the safety of pedestrians in the park.
[0093] The fire water spray processing module is used to determine whether there are people around the fire sprinklers in each fire hazard area of the park and each fire hazard affected area before fire water spraying. If there are people, a reminder will be broadcasted; if there are no people, the water flow spray directions and corresponding water pressure values of each fire hazard area of the park are calculated, and the humidity increase values of each fire hazard area of the park and the humidity increase values of each fire hazard affected area are evaluated, and corresponding fire fighting operations are performed.
[0094] In a specific embodiment of the present invention, the specific detection method for judging whether there are people around the fire sprinklers in each fire hazard area and each fire hazard affected area of the park is as follows: obtaining the geographical location of the fire sprinklers in each fire hazard area of the park from a local database, extracting the geographical location of each pedestrian in each fire hazard area of the park based on the geographical location of each pedestrian in each high temperature area of the park, and calculating the relative geographical location distance between the fire sprinklers in each fire hazard area of the park and the nearest pedestrian.
[0095] The safe fire fighting distance is obtained from the local database. If the relative geographical location distance between the fire sprinklers in a fire hazard area of the park and the nearest pedestrian is less than the safe fire fighting distance, it is judged that there are people around the fire sprinklers in the fire hazard area of the park. Otherwise, it is judged that there are no people around the fire sprinklers in the fire hazard area of the park, thereby judging whether there are people around the fire sprinklers in each fire hazard area of the park.

[0097] In a specific embodiment of the present invention, the water flow injection directions and corresponding water pressure values of each fire hazard area belonging to the park are calculated by the following specific calculation method: based on the geographical locations of each high-temperature object in each high-temperature area belonging to the park, the geographical locations of each remaining high-temperature object in each fire hazard area belonging to the park are extracted; based on the geographical locations of the fire sprinklers in each fire hazard area belonging to the park, the fire sprinklers in each fire hazard area belonging to the park are used as the starting point of the direction vector, and the geographical locations of each remaining high-temperature object in each fire hazard area belonging to the park are used as the focus of the direction vector, thereby obtaining the direction vectors of each fire hazard area belonging to the park, and using them as the water flow injection directions of each fire hazard area belonging to the park.
[0098] Obtain the relative geographical location distances between the fire sprinklers in each fire hazard area of the park and each remaining high-temperature object, obtain the water pressure values corresponding to each relative geographical location distance from the local database, map the required water pressure values for the fire sprinklers in each fire hazard area of the park to spray water to each remaining high-temperature object, and use them as the water pressure values for each water flow injection direction in each fire hazard area of the park.
[0099] In a specific embodiment of the present invention, the humidity increase value of each fire hazard area belonging to the park and the humidity increase value of each fire hazard affected area are evaluated by a specific evaluation method: the humidity increase value corresponding to each high-temperature combustion hazard coefficient interval is obtained from a local database, and the humidity increase value of each fire hazard area belonging to the park is mapped according to the high-temperature combustion hazard coefficient of each fire hazard area belonging to the park.
[0100] The humidity increase value corresponding to each combustion spread coefficient interval is obtained from the local database, and the humidity increase value of each fire hazard affected area of the park is mapped according to the combustion spread coefficient of each fire hazard affected area of the park.
[0101] In a specific embodiment, the corresponding fire-fighting operation is performed as follows: the water jet directions of each fire hazard area in the park and their corresponding water pressure values, humidity increase values and humidity increase values of each fire hazard affected area are sent to the fire terminal, and the fire terminal performs fire-fighting water jets on each fire hazard area in the park, and then performs humidity increase operations on each fire hazard area in the park and each fire hazard affected area.
[0102] The fire sprinkler treatment module of the present invention locates fires in various fire hazard areas of the park and humidifies the air in various fire hazard areas of the park and areas affected by fire hazards. Since the park is often large in scope, considering that continuous humidification is often extremely wasteful of water resources, humidification is only performed in time when fire hazards occur or are affected by fire hazards. While saving water resources, the possibility of fire is reduced, thereby ensuring the safety of the park.
