Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of lightning protection equipment, and particularly relates to a lightning comprehensive detection and early warning system and a lightning detection method thereof. BACKGROUND

[0002] For many years, the atmospheric electric field instrument used for lightning approaching detection has greatly improved the accuracy of detection and early warning, and has played a positive role in the power, petrochemical and meteorological industries in China. With the improvement of the accuracy of the early warning time, it is found that harmful lightning is not much, thus leading to a lot of ineffective lightning avoidance actions.

[0003] The main manifestations are that the distance of lightning distance early warning is how far, the position of lightning is where, the height of lightning from the ground is how high, and the harm of the lightning to be generated is how big, and if the lightning early warning system is not used, the equipment is worried about being damaged by lightning, but if the lightning early warning system is used, a lot of ineffective avoidance work appears.

[0004] In modern cities, meteorological radars are mostly set up for weather forecasting, and the radar echoes can accurately detect the position, distance and height of the lightning cloud and analyze the lightning energy according to the echo intensity, but cannot detect whether the lightning will occur. The atmospheric electric field instrument can detect that the lightning will occur, but cannot detect the position, distance, height and harm of the lightning to be generated. SUMMARY

[0005] In order to solve the problems in the prior art, the application provides a lightning comprehensive detection and early warning system and a lightning detection method thereof, which are networked by the outdoor movable small early warning equipment, and all the equipment data in the region are integrated by the server at the rear end to achieve the effect of regional lightning protection.

[0006] The technical scheme adopted by the application is,

[0007] A lightning comprehensive detection and early warning system is used for monitoring and early warning of characteristic values reflecting lightning formation conditions in meteorological data in a specific region, and comprises,

[0008] An atmospheric electric field detection module is used for detecting at least a characteristic value A containing electric field data of a lightning cloud in a specific region.

[0009] A meteorological radar module is used for detecting at least a characteristic value B containing geographic position data of a lightning cloud in a specific region.

[0010] A system module is used for connecting the atmospheric electric field detection module and the meteorological radar module and combining the received characteristic value A and the characteristic value B to form lightning early warning information.

[0011] First, now many cities or mass gathering areas are equipped with lightning warning and detection system to prevent lightning impact on facilities or personnel in the area. Lightning protection methods are varied, but are passive protection, the key point in lightning protection work is the pre-detection and early warning of lightning.

[0012] In many cities, weather radar is set up, mainly for weather forecasting, using modern science and technology to predict the state of the earth's atmosphere at a certain place in the future, mainly collecting a large amount of data such as temperature, humidity, wind direction and speed, air pressure, etc. The change of weather is mainly the physical state of the cloud in the atmosphere, by observing the reference characteristic value of the atmospheric cloud, and judging the weather change in a certain area in the future according to the research model.

[0013] Lightning is a natural phenomenon of lightning cloud accumulation forming polarity discharge, and its formation condition must exist lightning cloud, so the prediction of lightning is also through the prediction of lightning cloud formation and the observation of its state after formation. The existing weather radar can detect the position, density and height of the cloud layer, and can also detect its flow rate, movement direction and movement track, its main principle is to scan through 360° circumferential rotation and a certain angle of antenna, when the electromagnetic wave meets the cloud layer and scatters, the data is analyzed through the scattered signal, and the cloud layer simulation diagram is formed with the background of the regional map with coordinate system. Weather radar cannot know the actual state of the cloud in the area, but the system will judge the possibility of lightning cloud according to its density and size, and give an early warning when it reaches the set threshold.

[0014] Many weather stations are also equipped with lightning locator, which is an automatic detection device that uses the sound, light and electromagnetic field characteristics of lightning radiation to remotely measure lightning discharge parameters, and sends the preprocessed lightning data in real time through the communication system to the central data processing station for real-time processing. It can be continuously operated and record the time, location, intensity and polarity of lightning occurrence. The device can accurately locate the lightning after it occurs, that is, it cannot predict, but can monitor in real time. But its monitoring data can be used to feedback the accuracy of the lightning prediction system, because the location of lightning occurrence is included in the area where the weather radar judges that lightning may occur, so the geographical position judged by the weather radar belongs to set A, and the geographical position detected by the lightning locator belongs to the subset of set A. Through many verifications, the prediction model can be adjusted to improve its accuracy.

[0015] But through the lightning locator can only verify the prediction information occurred, but can not be directly applied in the prediction work, and many weather radar and prediction equipment are mostly set in the area where the personnel density is large, for some outdoor facilities or areas, in the position without setting weather radar, only through the satellite or the nearby weather radar to make a rough prediction and judgment, and the inaccurate early warning will affect the normal operation of some special facilities in the area, because once it is determined that lightning may occur, but the accurate occurrence position and time are not known, all facilities in the area need to be regulated, especially some oil production or transportation equipment, which need to be shut down and take strict lightning protection measures, and can resume normal operation after the lightning warning is eliminated.

[0016] The present application provides a mobile outdoor lightning comprehensive detection system, which has higher precision than the existing atmospheric electric field instrument, and can accurately obtain the position and size of the lightning cloud, so as to make accurate judgment. The atmospheric electric field detection module contained therein is an inductor which measures the characteristic value of the electric field by using the principle that a conductor generates induced charge in an electric field. In the present device, the characteristic value A of the lightning cloud is detected, which necessarily contains the electric field value in the region.

[0017] The weather radar module is a small radar antenna assembly which can scan a circular area of a certain radius value in a cycle after starting, mainly in the air, and constantly changes the elevation angle during the ring scanning, so as to rotate a ring-shaped scanning space with a fan-shaped scanning surface. In the space, a data packet is formed with the characteristic values of the cloud layer position, density, size, etc., that is, the characteristic value B, and is sent to the system module, which merges it with the detection value of the atmospheric electric field detection module, so as to obtain more accurate lightning prediction information.

[0018] That is, the atmospheric electric field detection module obtains a relatively rough regional lightning cloud electric field value, and once the electric field value exceeds the threshold value, it means that lightning may form, so that the position information and other information of the lightning cloud scanned by the superimposed weather radar are obtained, so as to accurately locate and obtain a more accurate lightning occurrence probability through multiple parameter references for early warning.

[0019] It is worth noting that the characteristic value A and the characteristic value B are two characteristic value sets containing a variety of different parameter values. For example, the weather radar module obtains the characteristic value B after a cycle, which contains the cloud density, cloud volume size, cloud flow rate, and spatial position of the cloud in a certain area, while the characteristic value A obtained by the atmospheric electric field detection module contains not only the electric field strength, but also the electric field strength change rate and other values, which can be accurately detected by multiple modules at the same time.

[0020] Further, the weather radar module covers C-band, X-band, K-band and U-band.

[0021] Further, the weather radar module is K-band.

[0022] The device in the application is mainly applied outdoors, and the size of the detection antenna is different due to the different wave bands. Common radio wave bands include U-band, Ka-band, K-band, Ku-band, X-band, C-band and S-band, each of which corresponds to different wavelength and frequency ranges. Taking C-band as an example, the frequency range is 4-8GHz, and the wavelength range is 37.5-76.0mm, and the commonly used antenna diameter is 2-5m. If the antenna size of the S-band and L-band radar commonly used by the weather station is large, although the detection accuracy is high, it is not suitable for the application, so according to the experiment, K-band is the most suitable, which can ensure good detection range and detection accuracy in a suitable size.

[0023] Further, when the electric field data detected by the atmospheric electric field detection module exceeds the threshold value, the system module controls the weather radar module to start and scan for at least one period.

[0024] The weather radar module belongs to an active microwave atmospheric remote sensing device, which is essentially a Doppler radar. Although it has good detection effect and detection range, the power consumption is high. The device disclosed in the application is mainly used outdoors, and if a battery is used for power supply in order to improve the mobile convenience, it cannot support continuous work. In order to improve the practicability, under normal conditions, the system module only controls the atmospheric electric field detection module to start working, which has low power consumption and can work stably for a long time. When the electric field data detected exceeds the threshold value, the weather radar module is started to scan, and a complete weather data information in the region can be obtained in one scanning period of 1-10min, and then a precise prediction information is obtained by the system module to give a warning.

[0025] Further, the atmospheric electric field detection module and the weather radar module form an integrated structure through the support provided, the support is provided with a mounting seat, and the mounting seat is provided with a plurality of atmospheric electric field detection modules.

[0026] Further, the system module comprises a control assembly provided on the support and a server in remote communication connection with the control assembly, and the atmospheric electric field detection module, the weather radar module and the control assembly are powered by a solar cell group provided on the support.

[0027] Further, the atmospheric electric field detection module and the weather radar module are each provided with an insulating protective shell outside.

[0028] Further, the support is further provided with a wind speed and direction testing module, a temperature detection unit, a humidity detection unit, a haze detection unit, a thunder and lightning sound detection unit and a thunder and lightning electromagnetic field detection unit connected with the control assembly.

[0029] A thunder and lightning detection method using the above-mentioned thunder and lightning comprehensive detection and early warning system, and the specific steps are as follows:

[0030] G1. First, assume the support in a specific area A, and set a map module with a coordinate system of the specific area A in the server;

[0031] G2. Then, control the atmospheric electric field detection module to perform real-time monitoring through the control assembly, and when at least one value in the characteristic value A exceeds a preset threshold value, the weather radar module is started to work;

[0032] G3. When the weather radar module completes a cycle of scanning and sends the characteristic value B to the control assembly, the control assembly sends the real-time characteristic value A and the characteristic value B to the server;

[0033] G4. The server first synthesizes an electric field coverage map of the characteristic value A and the map module, converts the characteristic value A into a cloud layer image and superimposes the cloud layer image in the electric field coverage map, and takes the overlapping area in the electric field coverage map and the cloud layer image as a warning area to perform early warning.

[0034] The detection radius of the radar in the embodiment exceeds 100 kilometers, because K wave band is used, the antenna is small, the detection distance is 30km, and the radar can be embedded and installed on the stand column, and has strong detection thunder cloud capacity.

[0035] The current mainstream radar is a dual-polarization Doppler weather radar, and common wave bands include S, C and X three wave bands, and the detection effect of the S wave band is the best, the C wave band is the second, and the X wave band is slightly poor. The construction cost of the S wave band is the most expensive, the X wave band is the cheapest, and the price of the C wave band is medium. The advantages of using the radar to detect thunder and lightning are that the radar can monitor the strength and movement of a large range of thunderstorms, and thus the radar has the ability to predict a "thunder and lightning occurrence area", which is superior to a lightning locator.

[0036] The beneficial effects of the present application are,

[0037] The present application combines a weather radar and an atmospheric electric field device, and embeds the weather radar device into the atmospheric electric field instrument, radar detection echo data is converted into an echo intensity color map superimposed on a map, and a thunder and lightning detection and early warning radar system is formed.

[0048] Embodiment 1,

[0049] The present embodiment discloses a lightning comprehensive detection and early warning system, comprising an atmospheric electric field detection module 1, a weather radar module 2 and a system module.

[0050] Among them, the atmospheric electric field detection module 1 is used to detect the characteristic value A of the lightning cloud in a specific area, which at least contains the electric field data; the weather radar module 2 is used to detect the characteristic value B of the lightning cloud in a specific area, which at least contains the geographic position data; the system module is used to connect the atmospheric electric field detection module 1 and the weather radar module 2, and form lightning warning information by combining the received characteristic value A and characteristic value B.

[0051] Among them, the characteristic value A and the characteristic value B are two characteristic value sets, containing a variety of different parameter values. For example, the weather radar module 2 contains the cloud layer density, cloud layer volume size, cloud layer flow rate, cloud layer space position, etc. in a specific area in the characteristic value B obtained after detection in a period, while the characteristic value A obtained by the atmospheric electric field detection module 1 contains not only the electric field intensity, but also the electric field intensity change rate and other values, which can be accurately detected synchronously by setting multiple modules.

[0052] Among them, the weather radar module 2 can detect the position, density and height of the cloud layer through electromagnetic waves, and can also detect the flow rate, movement direction and movement track of the cloud layer. Its main principle is to scan through the antenna rotating around the circumference and at a certain elevation angle. When the electromagnetic wave encounters the cloud layer and is scattered, the data is analyzed through the scattered signal, so as to form a cloud layer simulation diagram with the background of the regional map with coordinate system.

[0053] The weather radar cannot know the actual state of the cloud layer in the region, but the system can judge the possibility of the occurrence of lightning cloud according to the density and size, and give an early warning when it reaches the set threshold. Many weather radars and prediction devices are mostly set in areas with high population density. For some outdoor facilities or areas, in the position without setting weather radar, only satellite or nearby weather radar can be used for rough prediction and judgment, and inaccurate early warning will affect the normal operation of some special facilities in the region.

[0054] Because once it is determined that lightning may occur, but the exact location and time of occurrence is unknown, the need to regulate all facilities in the region, especially some oil production or transportation equipment, need to stop and take strict lightning protection measures, when the lightning warning is eliminated, it can resume normal operation. The embodiment provides a mobile outdoor lightning comprehensive detection system, compared with the existing atmospheric electric field instrument, its precision is higher, and the position and size of the lightning cloud can be accurately obtained, so that accurate judgment can be made. The atmospheric electric field detection module 1 contained therein is an inductor, which measures the characteristic value of the electric field by using the principle that the conductor generates induced charge in the electric field. In the device, the characteristic value A of the lightning cloud is detected, which necessarily contains the electric field value in the region.

[0055] In the embodiment, the weather radar module 2 covers C-band, X-band, K-band and U-band.

[0056] Embodiment 2:

[0057] The embodiment discloses a lightning comprehensive detection and early warning system, which comprises a support 3 and an atmospheric electric field detection module 1, a weather radar module 2 and a system module arranged on the support 3.

[0058] The atmospheric electric field detection module 1 and the weather radar module 2 form an integrated structure through the support 3, the support 3 is provided with a mounting seat 4, and a plurality of atmospheric electric field detection modules 1 are arranged on the mounting seat 4.

[0059] The support 3 structure in the embodiment is as shown in Figure 1 and Figure 2 The weather radar module 2 is arranged at the top, protected by a disc-shaped insulating protective shell, a wind direction and wind speed detection sensor module is arranged below the weather radar module 2, and a mounting seat 4 with four connecting holes is further arranged below.

[0060] The system module comprises a control assembly 5 arranged on the support 3 and a server in remote communication connection with the control assembly 5, and the atmospheric electric field detection module 1, the weather radar module 2 and the control assembly 5 are powered by a solar cell group 6 arranged on the support 3.

[0061] The mounting seat 4 is sleeved on the rod of the support 3, and one mounting hole is arranged in each of the four 90°-divided directions in the circumferential direction, and an L-shaped connecting rod is inserted in the mounting hole. An atmospheric electric field detection module 1 is arranged at the end of the L-shaped connecting rod, and the atmospheric electric field detection module 1 is smaller than the weather radar module 2, wherein an antenna is integrated for signal transmission and reception, and the connecting line is built in the L-shaped connecting rod to connect with the control assembly 5 below.

[0062] The control component 5 is arranged in the electrical box and is fixed on the bottom plate of the support 3 through the mounting frame, and a solar cell panel is arranged on the other side of the electrical box to provide power for the entire device. That is, the device in the embodiment is a movable modular device completely arranged outdoors, and various functional modules can be arranged on the support 3 according to requirements.

[0063] It is worth noting that the weather radar module 2 in the embodiment is a K-band.

[0064] And because the weather radar of K-band is used, and the solar cell group 6 is used for power supply, when the electric field data detected by the atmospheric electric field detection module 1 exceeds the threshold value, the system module controls the weather radar module 2 to start and perform at least one cycle of scanning

[0065] The support 3 is further provided with a wind speed and direction test module, a temperature detection unit, a humidity detection unit, a haze detection unit, a lightning sound detection unit and a lightning electromagnetic field detection unit connected with the control component 5.

[0066] The specific detection and early warning method of the system is as follows:

[0067] First, the support 3 is assumed in a specific area A, and a map module with a coordinate system of the specific area A is arranged in the server. According to the actual size and terrain of the specific area A, the specific area A can be divided into multiple detection blocks, and the support 3 with the atmospheric electric field detection module 1 is arranged on each block, and the data is transmitted to the server at the same time. Only one system with the weather radar module 2 can be arranged in multiple areas.

[0068] Then, the control component 5 arranged on each support 3 controls the atmospheric electric field detection module 1 to perform real-time monitoring, and when at least one value of the characteristic value A exceeds the preset threshold value, the weather radar module 2 is started to work; after the weather radar module 2 completes one cycle of scanning and sends the characteristic value B to the control component 5, the control component 5 sends the real-time characteristic value A and the characteristic value B to the server.

[0069] It is worth noting that because one weather radar module 2 is arranged in multiple blocks, the server determines that once the characteristic value A of the atmospheric electric field detection module 1 on any block in the entire specific area A exceeds the threshold value, the closest weather radar module 2 is started to detect, and the synthesized coverage map with the terrain background is sent to the client for early warning.

[0070] The server first synthesizes the characteristic value A and the map module to form an electric field coverage map, converts the characteristic value A into a cloud image and superimposes the cloud image on the electric field coverage map, and takes the overlapping area in the electric field coverage map and the cloud image as a warning area for early warning.

[0071] The detection radius of the radar in this embodiment exceeds 100 kilometers. Since the K-band is used, the antenna is small, the detection distance is 30 km, and the radar can be embedded on the column of the support 3, and has strong detection ability for thunderstorm clouds.

[0072] The mainstream radar at present is a dual-polarization Doppler weather radar. Commonly used wave bands include S, C, and X wave bands. The detection effect of the S wave band is the best, the C wave band is the second, and the X wave band is slightly worse. The construction cost of the S wave band is the most expensive, the X wave band is the cheapest, and the price of the C wave band is medium. The advantages of using the radar to detect lightning are that the radar can monitor the strength and movement of a large range of thunderstorms, and thus the radar has the ability to predict the “lightning occurrence area”, which is superior to a lightning locator.

[0073] The specific radar identification method is to identify thunderstorms by using the DBSCAN (Density-Based Spatial Clustering of Applications with Noise) algorithm. This method has the following characteristics:

[0074] Radar data gridding processing: form three-dimensional grid echo data in a rectangular coordinate system, with a spatial resolution of 1 km x 1 km x 1 km;

[0075] Based on the automatic threshold technology proposed by Gonzalez et al., suitable seven-layer identification thresholds are selected:

[0076] Initial threshold (30 dBZ), and the last six-layer thresholds (35, 40, 45, 50, 55, and 60 dBZ)

[0077] Among them, the extraction of the feature core is mainly to retain the thunderstorm components identified by the internal highest reflectivity factor threshold, and all lower reflectivity factor thunderstorm components containing the highest reflectivity factor core thunderstorm component are discarded.

[0078] Vertically associate all two-dimensional thunderstorm components to construct a three-dimensional thunderstorm monomer. Calculate the horizontal distance between the centroid of a thunderstorm extraction component on the contour surface H and the centroid of each thunderstorm component on the contour surface H-1, and associate the two thunderstorm components with the smallest centroid horizontal distance and the horizontal distance less than 7.5 km. After associating all the thunderstorm components on the contour surface H that meet the conditions with the thunderstorm components on the contour surface H-1, the remaining false thunderstorm components are removed. Calculate the characteristic quantity of all thunderstorm monomers, and perform vertical projection on each thunderstorm monomer and store it as a reflectivity factor polygon area. The area is the cloud layer image of the lightning cloud.

[0079] The application is not limited to the above-mentioned optional embodiments, and anyone can derive other various forms of products under the inspiration of the application. The above-mentioned specific embodiments should not be understood as limiting the protection scope of the application, and the protection scope of the application should be defined by the claims, and the specification can be used to explain the claims.
