Abstract
Description
Technical Field
[0001] The invention relates to the field of lightning early warning, and in particular to a lightning early warning monitoring device. Background Art
[0002] When thunderclouds form or approach, the electric field strength of the geostatic field will show significant changes. Therefore, the atmospheric electric field instrument that monitors the ground atmospheric electric field is used to detect and analyze thunderclouds, which can achieve lightning warning. Lightning warning means predicting that a lightning strike may occur at a very specific location (such as an oil depot) before the lightning strike occurs, thereby providing a basis for lightning protection for workers in open-air workplaces and flammable and explosive places. Therefore, lightning warning can greatly reduce the harm of lightning strikes to human society.
[0003] The current lightning warning system mainly uses an atmospheric electric field meter to monitor the atmospheric electric field. Its working principle is that the electric field meter monitors the atmospheric electric field value in real time and sends it to the computer. When the received atmospheric electric field value is greater than the preset value, the computer sends an alarm message to indirectly predict the lightning activity. The most critical condition for thunderclouds to discharge to the ground is that the electric field strength of the thundercloud to the earth must reach a certain value. Therefore, monitoring the electric field generated by thunderclouds can indirectly analyze the activity of lightning. The electric field meter monitors the atmospheric electric field 24 hours a day and records the electric field data at every moment. These data can be compared with normal data to analyze the possibility of lightning. Since the atmospheric electric field value may mutate due to changes in the surrounding environment, such as the passing of cars with static electricity, people or animals, etc., the measured value of the electric field meter may mutate, causing false alarms.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0052] The inventors have found that the existing lightning early warning monitoring device has certain shortcomings. For example, due to wireless connection or the lack of an alarm 2, there may be problems such as unclear alarm information and low alarm accuracy. Unclear alarm information and false alarms will lead to the inability to take timely countermeasures, seriously affecting the normal work of field workers. Taking measures after false alarms will also lead to waste of resources. In addition, some devices transmit through unstable wireless networks, which will cause delays in alarm information.
[0053] Based on this, an embodiment of the present invention provides a lightning early warning monitoring device, which is described below through specific embodiments.
[0054] Example
[0055] The embodiment of the present invention provides a lightning early warning monitoring device, referring to Figure 1-Figure 3As shown, it includes a MEMS atmospheric electric field meter 1, an alarm 2 and a storage terminal 3 which are electrically connected in sequence;
[0056] The MEMS atmospheric electric field instrument 1 is capable of monitoring the atmospheric electric field and transmitting atmospheric electric field data to the alarm 2;
[0057] The alarm device 2 includes an MCU control module 21 and a display module 22 and an alarm module 23 respectively connected to the MCU control module 21;
[0058] The MCU control module 21 can generate an electric field strength waveform based on the atmospheric electric field data, analyze the electric field strength waveform to remove abnormal information and generate alarm information, and send instructions to the alarm module 23 according to the intensity of the alarm information so that the alarm module 23 issues the alarm information;
[0059] The display module 22 can display alarm information;
[0060] The storage terminal 3 is used to store alarm information.
[0061] In an embodiment of the present invention, the MEMS atmospheric electric field instrument 1 is arranged in an open outdoor space, and the building height around the MEMS atmospheric electric field instrument 1 needs to be less than the distance between the building and the MEMS atmospheric electric field instrument 1 to ensure safe and accurate monitoring. The MEMS atmospheric electric field instrument 1 can monitor the atmospheric electric field in real time, thereby obtaining atmospheric electric field data, and the atmospheric electric field data may include atmospheric electric field intensity data and atmospheric electric field change rate data. The alarm 2 and the storage terminal 3 can be arranged in the integrated control room near the MEMS atmospheric electric field instrument 1.
[0062] In the embodiment of the present invention, the MCU control module 21 can extract the atmospheric electric field strength data within a period of time (for example, 5 minutes), and generate an electric field strength waveform based on the atmospheric electric field data during this period; the MCU control module 21 has a built-in artificial intelligence algorithm, which can analyze the characteristic value of the generated electric field strength waveform, thereby identifying and eliminating abnormal information and generating more accurate alarm information. The characteristic values of the electric field strength waveform can include rise time, waveform steepness and transient amplitude, etc., which can reflect the atmospheric electric field strength. Taking the rise time as an example, the rise time is generally defined as the time required to rise from 10% of the waveform to 90% of the waveform. The shorter the rise time, the faster the waveform changes. If the rise time of the electric field strength waveform is too short, it means that the electric field strength changes too fast in a short time, which is different from the electric field strength change of the general lightning warning. It can be determined that the electric field strength change during this period is abnormal. Correspondingly, the waveform steepness and transient amplitude of the electric field strength waveform can also reflect the abnormal information of the electric field strength. The specific relevant principles are well known to those skilled in the art, and can be referred to the detailed records in the prior art. Here, no further description is given. The artificial intelligence algorithm built into the MCU control module 21 can identify and eliminate such abnormal information when generating alarm information. The specific process of generating alarm information may include:
[0063] Obtain the rise time, waveform steepness and transient amplitude of the electric field strength waveform;
[0064] The rise time, waveform steepness and transient amplitude of the acquired electric field strength waveform are respectively compared with the preset rise time threshold, waveform steepness threshold and transient amplitude threshold;
[0065] Assign values according to the obtained rise time comparison result, waveform steepness comparison result and transient amplitude comparison result, respectively, to obtain rise time assignment, waveform steepness assignment and transient amplitude assignment;
[0066] Based on the rise time assignment, waveform steepness assignment, transient amplitude assignment and the corresponding preset weights, the alarm intensity value is determined, the alarm intensity value is compared with the preset alarm intensity threshold, and an alarm message is generated.
[0067] In the embodiment of the present invention, the MCU control module 21 can also automatically perform filtering after generating the electric field strength waveform to improve the accuracy of the electric field strength waveform.
[0068] In the embodiment of the present invention, the storage terminal 3 can store each alarm information and can retrieve the stored alarm information, so that the staff can obtain the alarm information of any time period.
[0069] In order to explain the embodiments of the present invention more clearly, taking the three-level alarm intensity as an example, the following embodiments are provided to introduce in detail the specific process of the artificial intelligence algorithm built into the MCU control module 21 generating alarm information. The specific process of the artificial intelligence algorithm built into the MCU control module 21 generating alarm information may include:
[0070] Obtaining the rise time, waveform steepness and transient amplitude of the electric field strength waveform, and determining the preset weights of the rise time, waveform steepness and transient amplitude respectively;
[0071] Determine a first rise time threshold, a second rise time threshold, a third rise time threshold, and a fourth rise time threshold, assign a rise time threshold range that is less than / equal to the first rise time threshold to 0, assign a rise time threshold range that is greater than the first rise time threshold and less than / equal to the second rise time threshold to 1, assign a rise time threshold range that is greater than the second rise time threshold and less than / equal to the third rise time threshold to 2, and assign a rise time threshold range that is greater than the third rise time threshold and less than / equal to the fourth rise time threshold to 3;
[0072] Determine a first waveform steepness threshold, a second waveform steepness threshold, a third waveform steepness threshold, and a fourth waveform steepness threshold, assign a waveform steepness threshold range greater than / equal to the first waveform steepness threshold to 0, assign a waveform steepness threshold range less than the first waveform steepness threshold and greater than / equal to the second waveform steepness threshold to 1, assign a waveform steepness threshold range less than the second waveform steepness threshold and greater than / equal to the third waveform steepness threshold to 2, and assign a waveform steepness threshold range less than the third waveform steepness threshold and greater than / equal to the fourth waveform steepness threshold to 3;
[0073] Determine a first transient amplitude threshold, a second transient amplitude threshold, a third transient amplitude threshold, and a fourth transient amplitude threshold, assign a transient amplitude threshold range greater than / equal to the first transient amplitude threshold to 0, assign a transient amplitude threshold range less than the first transient amplitude threshold and greater than / equal to the second transient amplitude threshold to 1, assign a transient amplitude threshold range less than the second transient amplitude threshold and greater than / equal to the third transient amplitude threshold to 2, and assign a transient amplitude threshold range less than the third transient amplitude threshold and greater than / equal to the fourth transient amplitude threshold to 3;
[0074] Compare the acquired rise time with each rise time threshold, determine the rise time threshold range that the rise time meets, and use the value of the rise time threshold range as the rise time value of the electric field strength waveform;
[0075] The acquired waveform steepness is compared with each waveform steepness threshold value, and a waveform steepness threshold range that the waveform steepness meets is determined, and the value of the waveform steepness threshold range is used as the waveform steepness value of the electric field intensity waveform;
[0076] The obtained transient amplitude is compared with each transient amplitude threshold value, and the transient amplitude threshold value range that the transient amplitude meets is determined, and the value of the transient amplitude threshold value range is used as the transient amplitude value of the electric field strength waveform;
[0077] The alarm intensity threshold range for the first level alarm is determined to be 0-1, the alarm intensity threshold range for the second level alarm is determined to be 1-2, and the alarm intensity threshold range for the third level alarm is determined to be 2-3;
[0078] The rise time value, the waveform steepness value and the transient amplitude value are multiplied by their respective preset weights and then added together to obtain the alarm intensity value;
[0079] Determine which level of the alarm intensity threshold range the alarm intensity value is in, and generate alarm information of different levels.
[0080] In this embodiment, a rise time that is too short, a waveform steepness that is too high, and a transient amplitude that is too large can all indicate that the electric field strength is abnormally fluctuating. Therefore, the rise time threshold range that is less than / equal to the first rise time threshold is assigned to 0, the waveform steepness threshold range that is greater than / equal to the first waveform steepness threshold is assigned to 0, and the transient amplitude threshold range that is greater than / equal to the first transient amplitude threshold is assigned to 0. This is to eliminate abnormal information and thus improve the alarm accuracy.
[0081] The above embodiment only illustrates the specific process of the artificial intelligence algorithm built into the MCU control module 21 to generate alarm information, and does not limit the implementation method of the specific process of the artificial intelligence algorithm built into the MCU control module 21 to generate alarm information. The characteristic values of the electric field strength waveform include but are not limited to rise time, waveform steepness and transient amplitude, and can also be other characteristic values that can reflect the change of electric field strength. It can be reasonably selected according to factors such as the environment in which the MEMS atmospheric electric field instrument 1 is located, and is not limited here. The number of alarm levels can be reasonably set according to actual needs. Correspondingly, the number of relevant threshold values of characteristic values such as rise time, waveform steepness, transient amplitude, etc. can be set accordingly according to the needs of the alarm level, and is not limited here.
