[0037] At present, non-lightning-terminal lightning protection equipment is widely used in lightning protection systems in many fields. The working principle of non-lightning-terminal lightning protection equipment is to use the multi-pin tip effect to realize the potential trap, capture the lightning leader of the thundercloud through the TV trap, and in the process of accumulating the charge of the lightning leader, a certain intensity of dissipative current is generated through strong ionization at room temperature to discharge the charge in the captured lightning leader, inhibit the breakdown discharge of the lightning leader, thereby terminating the formation process of lightning strikes and achieving effective lightning protection and lightning avoidance. It realizes the early prevention of lightning strikes before the lightning strike occurs, so it is relatively "quiet" during the working process, so it is difficult to judge the working status of the equipment by direct observation.

[0038] However, it is difficult to monitor non-lightning protection equipment, mainly due to the following reasons: First, in order to avoid introducing interference, the working current of non-lightning protection equipment cannot be monitored by direct series measurement. Secondly, since the working current of non-lightning protection equipment is relatively small, usually only a dozen milliamperes, and it is directly connected to the grounding system, it is also difficult or costly to measure by electromagnetic induction. Finally, during the operation of non-lightning protection equipment, serious electric field distortion will occur within its protection range. This electric field distortion makes it impossible to perform indirect detection by measuring the changes in the surrounding electric field strength, and it is impossible to judge the working status of non-lightning protection equipment based on the measurement results.

[0039] To solve the above problems, this application provides a monitoring device, please refer to Figure 1 and Figure 2 , Figure 1 FIG. 1 shows a schematic diagram of the structure of a monitoring device in an embodiment of the present application. Figure 2 The data management mechanism 50 of the monitoring device in one embodiment of the present application is shown in the structural diagram.

The control box 60 is arranged on the support 10, and the data management mechanism 50 is arranged in the control box 60. The data management mechanism 50 includes a data processing component 53 electrically connected to the sound source collection mechanism 20, and the data processing component 53 is used to receive the audio signal output by the sound source collection mechanism 20, form a voiceprint model based on the audio signal, and compare the formed voiceprint model with the pre-stored standard voiceprint model to obtain the working state of the non-lightning protection device.

[0041] The monitoring device provided in the present application collects the audio signal of the non-lightning protection equipment, forms a voiceprint model based on the audio signal, and compares the formed voiceprint model with the pre-stored standard voiceprint model to obtain the working status of the non-lightning protection equipment, thereby realizing real-time monitoring of the working status of the non-lightning protection equipment. There is no need to rely on electrical characteristic indicators as a basis for monitoring, which can reduce the risk of lightning caused by the failure of non-lightning protection equipment and ensure the safe and stable operation of important infrastructure such as buildings, communications, and electricity.

[0063] In some embodiments, the data receiving component 51 is electrically connected to the sound source acquisition mechanism 20 and the data storage component 52 respectively. The data receiving component 51 is used to receive the audio signal output by the sound source acquisition mechanism 20, convert the audio signal into audio data, and store the audio data in the data storage component 52.

[0064] In some embodiments, the data storage component 52 is electrically connected to the data processing component 53; the data processing component 53 is used to analyze and process the unprocessed audio data in the data storage component 52, and mark the audio data as processed. The data storage component 52 is used to receive and store the monitoring result data output by the data processing component 53 in chronological order.

[0065] In some embodiments, the data transmission component 54 is electrically connected to the data storage component 52, and is used to send the monitoring result data in the data storage component 52 to the monitoring management device in the order in which the data is generated, and mark the data that has been transmitted as transmitted. In some embodiments, the data transmission component 54 uses the fourth generation mobile communication technology (4G) or the fifth generation mobile communication technology (5G) for data transmission to achieve efficient and stable data transmission.

Among them, these data include but are not limited to time data, standard voiceprint model and communication basic data.

[0067] In some embodiments, the integrated management component 55 transmits the working status information of the battery component, power management component, data receiving component 51, data storage component 52, data processing component 53, data transmission component 54 and integrated management component 55 in the control box 60 to the monitoring management device through the data transmission component 54, which helps to improve the monitoring efficiency of the monitoring device and improve the reliability of the monitoring device. In some embodiments, the integrated management component 55 can upload the sound samples of the non-lightning protection equipment through the data transmission component 54, and receive the pre-stored standard voiceprint model that has not yet been issued by the system.

[0068] In some embodiments, the integrated management component 55 is used to monitor the power of the battery component; when the power of the battery component is lower than a specific value and the charging component 40 cannot be started, the integrated management component 55 controls all components in the monitoring device that require electricity except the integrated management component 55 to stop working and enter a dormant state; when the power of the battery component is higher than a specific value or the charging component 40 can be started, the integrated management component 55 starts all previously stopped components; this helps to improve the stability of the monitoring device and data security. In this embodiment, the specific value is 8%; in other embodiments, the specific value can also be set to 5%, 10%, 15%, etc., so it is not limited to this.

[0069] In some embodiments, the integrated management component 55 is used to control the start and stop of the data transmission module according to whether there is untransmitted data in the data storage component 52, so as to reduce the energy consumption of the monitoring device. In some embodiments, the integrated management component 55 is used to monitor the storage space usage of the data storage component 52, and when the unused space is lower than the threshold, the data marked as processed and transmitted in the data storage component 52 is cleared. In this embodiment, the threshold is 25%; in other embodiments, the threshold can also be set to 20%, 30%, 35%, etc., so it is not limited to this.

[0070] When in use, the monitoring device provided by the present application does not need to be physically connected to the non-lightning protection equipment, and has no effect on the non-lightning protection equipment. The monitoring device can collect the audio signal of the non-lightning protection equipment in real time through the sound source collection mechanism 20, and receive the audio signal through the data processing component 53, analyze and process the audio signal and output the monitoring result data, thereby realizing real-time monitoring of the working status of the non-lightning protection equipment, which can effectively reduce the lightning risk caused by the failure of the non-lightning protection equipment and ensure the safe and stable operation of important infrastructure such as buildings, communications, and electricity.

[0071] The present application also provides a monitoring method for non-lightning-termination lightning protection equipment, comprising the following steps:

[0072] S1. Install the monitoring device at intervals on one side of the non-lightning protection equipment.

[0073] S2. The audio signal of the non-lightning-connection lightning protection device is collected in real time through the sound source collection mechanism 20.

[0074] S3. Receive an audio signal through the data processing component 53, and form a voiceprint model based on the audio signal.

[0075] S4. The formed voiceprint model is compared with the pre-stored standard voiceprint model through the data processing component 53 to obtain the working status of the non-lightning protection device and output the monitoring result data.

[0076] In some embodiments, step S3 further includes the following steps:

[0077] S31, normalize the audio signal, limit the sample amplitude of the audio signal to the range of [-1, 1]; use a first-order digital filter with 6dB / octave to perform pre-emphasis processing, and perform windowing and framing on the audio signal.

[0078] S32, performing fast Fourier transform (FFT) on the normalized data to calculate the frequency parameters of each frame of data.

[0079] S33, performing convolution operation on the spectrum parameters of each frame of data through a Mel frequency filter composed of a triangular bandpass filter, and then taking the logarithm of the output of each frequency band to calculate the logarithmic energy of each output.

[0080] S34, performing discrete cosine transform to obtain Mel-frequency cepstral coefficients (MFCC) as voiceprint feature parameters.

[0081] S35. After extracting the voiceprint feature parameters, a Gaussian mixture model (GMM) is used to model the voiceprint feature parameters, and the voiceprint feature parameters are transformed into a voiceprint model that can be used for comparison.

[0082] In some embodiments, in step 31, the frame length of windowing and framing the audio signal is 30 ms.

[0083] In some embodiments, the monitoring result data in step S4 includes but is not limited to comparison results, sound energy intensity and other data.

[0084] In some embodiments, the working state of the non-lightning protection device in step S4 includes but is not limited to normal working state, overvoltage state, fault state, maintenance state, etc. The pre-stored standard voiceprint model includes but is not limited to normal working state voiceprint model, overvoltage state voiceprint model, fault state voiceprint model, maintenance state voiceprint model, etc. The data processing component 53 compares the real-time formed voiceprint model with the pre-stored standard voiceprint model. If the real-time voiceprint model has the highest similarity with a certain standard voiceprint model, it is considered that the non-lightning protection device is in the working state corresponding to a certain standard voiceprint model.

[0085] The monitoring method for non-lightning protection equipment provided in the present application can monitor and warn the working status of the non-lightning protection equipment in real time, has high monitoring efficiency, and helps to promptly discover and handle abnormal conditions of the non-lightning protection equipment, improve the reliability and stability of the non-lightning protection equipment, and effectively reduce the lightning risk caused by the failure of the non-lightning protection equipment.
