Example 1
Referring to fig. 1, fig. 1 is a schematic view illustrating steps of a lightning protection method for a building according to an embodiment of the present invention, which is shown as follows:
step S100, receiving weather information of an environment where a building is located, wherein the weather information at least comprises position information and atmospheric electric field intensity;
in some embodiments, since sufficient electric field strength is required for the formation of a lightning strike, in this embodiment, weather information in the building environment may first be obtained by an atmospheric electric field strength sensor. In order to obtain more accurate weather information, whether lightning strike danger exists or not and the thundercloud azimuth is determined by subsequent judgment, in the embodiment, a plurality of atmospheric electric field strength sensors are arranged in the building environment, and the atmospheric electric field strength above the building environment and the building environment is detected by the atmospheric electric field strength sensors together to prevent the occurrence of accidental situations of inaccurate detection. Obviously, the atmospheric electric field intensity value detected by the atmospheric electric field intensity sensor closer to the thundercloud position is larger, the noise reduction, modulation and demodulation of the signal are easier, and therefore the influence of the measurement error of the sensor on the detection result is avoided. Therefore, the atmospheric electric field strength sensor should be installed at a high position as much as possible.
Step S110, pre-judging the lightning stroke danger degree of the building through traversing the acquired weather information data;
in some embodiments, in order to avoid the error of the atmospheric electric field intensity caused by the interference of the external factors in the suspected atmospheric electric field intensity, the second screening is performed on all the suspected atmospheric electric field intensities. And finding out the corresponding atmospheric electric field intensity sensor for acquiring each suspected atmospheric electric field intensity as the suspected atmospheric electric field intensity sensor. And finding two atmospheric electric field intensity sensors with the plane distance less than or equal to the preset adjacent distance by taking the suspected atmospheric electric field intensity sensor as a center, and using the two atmospheric electric field intensity sensors as auxiliary atmospheric electric field intensity sensors for judging whether the atmospheric electric field intensity detected by the suspected atmospheric electric field intensity sensor is the real lightning stroke risk degree. For example: in doubt, the atmospheric electric field intensity sensor A finds out auxiliary atmospheric electric field intensity sensors B and C within 10 meters of the plane A. The main controller acquires weather information sent by the auxiliary atmospheric electric field intensity sensor in a centralized manner as auxiliary weather information. According to the fact that thunderclouds in which lightning strokes occur are not completely sudden changes of the atmospheric electric field intensity, but the cloud layers around the thunderclouds simultaneously have fluctuation changes of the atmospheric electric field intensity, only when auxiliary weather information detected by an auxiliary atmospheric electric field intensity sensor exceeds a preset fluctuation electric field intensity, the fact that the cloud layers around the thunderclouds with suspected atmospheric electric field intensity also have fluctuation of the atmospheric electric field intensity can be proved, and then the fact that the suspected atmospheric electric field intensity is the lightning stroke risk is proved, and error information is not generated due to failure of the atmospheric electric field intensity sensor or interference of external environmental factors.
And step S120, if the risk exceeds a preset threshold, determining that a building lightning protection plan is started in a thundercloud direction and/or performing lightning protection preparation work in advance according to the atmospheric electric field intensity.
In some embodiments, when the detected atmospheric electric field strength is determined as a lightning risk, an alarm instruction may be sent to an alarm, and the alarm may generate a corresponding warning signal after receiving the alarm instruction, such as a whistle, a warning light, and the like, to notify a worker. After receiving the alarm instruction, the worker can determine whether lightning protection work is necessary according to specific environmental conditions, if the lightning protection work is necessary, the worker sends a confirmation instruction to the main controller through the mobile device, and after receiving the confirmation instruction, the main controller executes a task of adjusting the working parameters of the ultraviolet laser.
Example 2
Referring to fig. 2, fig. 2 is a detailed schematic diagram of a lightning protection method for a building according to an embodiment of the present invention, which is as follows:
and S200, establishing a regional weather information acquisition center by taking the center of the region where the building is located as the center of a circle, wherein the regional weather information acquisition center consists of a plurality of concentric circles, different weather information acquisition centers are formed between two adjacent concentric circles, and the confidence coefficient of weather information data is gradually reduced from inside to outside.
Step S210, the regional weather information collection center includes, from inside to outside, a level 1 data collection area, a level 2 data collection area, a level 3 data collection area, and a level 4 data collection area, and the confidence of the weather information data is divided into a level 1 confidence, a level 2 confidence, a level 3 confidence, and a level 4 confidence from inside to outside.
Step S220, obtaining an interference plus noise ratio SINR value in weather information data, calculating weather data throughput of a target building according to the SINR value to be used as basic throughput, and obtaining an attenuation index of a regional weather information collection center, wherein the regional weather information collection center is added with a single regional weather information collection center in the building, according to path loss and power loss of the single regional weather information collection center.
And step S230, acquiring total interference suffered by the building after the building is accessed into a single regional weather information acquisition center according to the distance distribution function of the building, the probability function of the regional weather information acquisition center and the interference distribution function, and acquiring the attenuation index of the regional weather information acquisition center according to the total interference.
Step S240, determining the suspected atmospheric electric field intensity of which the atmospheric electric field intensity is greater than or equal to a preset threshold, determining the position of the regional weather information acquisition center corresponding to the risk, arranging the risk corresponding to each regional weather information acquisition center according to the sequence from high to low in a preset detection range, and determining at least the first three regional weather information acquisition centers.
Step S250, acquiring a detection coverage area of each of the drawing sensors; and superposing all the detection coverage ranges, determining the orientation of the thundercloud, and acquiring a simulated moving path of the thundercloud according to the deflection direction and the deflection angle of the thundercloud, so as to start a building lightning protection plan and/or perform lightning protection preparation work in advance.
In some embodiments, the traversal data may be data obtained after information acquisition, experiment, and test are performed on all roads in an area where the target building is located or roads in an area where the target building is located at a preset proportion (for example, 80%) at a preset speed within a preset time by using a preset number of test terminals; the data may include: SINR value at individual user level, uplink and downlink throughput, occupied network bandwidth, etc. The preset number, the designated vehicle speed, the preset time and the preset ratio may be set by a person skilled in the art according to actual conditions, which is not limited by the present invention. Each piece of acquired traversal data is traversal data of a single user, so that the SINR value corresponds to the SINR value of the single user. When calculating the basic throughput, the relationship expression and the relationship parameter of the throughput of the single user terminal and the SINR value of the single user obtained by the actual test can be obtained, and the relationship expression and the relationship parameter are used as the basis for calculating the throughput of the single user terminal according to the SINR value.
In order to further clarify the lightning risk degree, a manager can conveniently appoint corresponding lightning protection measures according to the lightning risk degree and provide guidance for lightning protection management work, a regional risk degree grading target is established by taking the center of a region (a region A) where a building is located as a circle center, the regional risk degree grading target is composed of a plurality of concentric circles, different regional risk degree grades are formed between every two adjacent concentric circles, and the risk degree grades are gradually reduced from inside to outside. And acquiring the position of the modified thunderstorm cloud simulation moving path L on the regional risk classification target, and taking the highest risk grade of the modified thunderstorm cloud simulation moving path L passing through the regional risk classification target as the lightning stroke risk of the region at the current time.
For example, a regional risk classification target is established by taking the center of an area A where a building is located as a circle center, and the regional risk classification target comprises a level 1 risk area, a level 2 risk area, a level 3 risk area and a level 4 risk area from inside to outside. The 1-level danger degree area is the position of an area A where a building is located, is an area with the highest lightning risk degree, and has the highest risk degree grade. The outside of the A area where the building is located is a 2-level danger area, the outside of the 2-level danger area is a 3-level danger area, and the 2-level danger area and the 3-level danger area cover the maximum monitoring range of the near-end early warning device and the far-end early warning device. The width of the class 2 hazard zone is less than the width of the class 3 hazard zone. For example, the level 2 risk area covers the maximum monitoring range of the near-end early warning device, and the level 3 risk area covers the maximum monitoring range of the far-end early warning device. The level 4 risk zone is a low risk zone with the lowest risk rating.
And determining whether to start a building lightning protection plan or to carry out lightning protection preparation work in advance according to the obtained risk level. Or when the lightning stroke risk degree of the area where the building is located is larger than the risk degree threshold value, the lightning is released in advance by adopting a method of artificial lightning triggering or active lightning triggering, the risk of the building group suffering from lightning stroke is reduced, and dangerous accidents such as fire disasters and the like caused by the lightning stroke of the building group are avoided.

and the confirmation output module 30 is used for determining that the thundercloud azimuth starts a building lightning protection plan and/or performs lightning protection preparation in advance according to the atmospheric electric field intensity if the risk exceeds a preset threshold.
