Description

Technical Field

[0001] The invention relates to the technical field of power equipment data processing, and in particular to a miniature portable personal protection sensing alarm device. Background Art

[0002] Inductive electric shock is one of the high-risk hidden dangers during the maintenance and inspection of electrical equipment in power plants. Currently, common insulating tools to avoid electric shock include insulating boots, insulating gloves, insulating mats, etc., but insulating tools cannot determine whether the induced electricity exists in the area. The inductive device detects the induced electricity and supplies it to the alarm device, which triggers an audible and visual alarm to remind the operation and maintenance personnel that there is an inductive belt in this area, and remind the staff around them to pay attention to insulation safety measures to protect personal safety. Therefore, a micro-portable personal protection inductive alarm device will be particularly important, directly or indirectly improving the reliability of personal safety.

[0003] The insulating tools currently available on the market can only prevent electric shock injuries, but cannot determine whether there is real induced electricity in the electrical equipment maintenance and inspection areas. If the operation and maintenance personnel forget to wear insulating tools due to carelessness at work, or if they have been working normally with insulating tools before, they mistakenly believe that there is no induced electricity in the area, and take off the insulating tools for ease of operation, then the probability of induced electric shock accidents will increase significantly.

[0004] The design of a micro portable personal protection induction alarm device now needs to overcome the following technical problems: the micro portable personal protection induction alarm device includes an induction electric detection device, an audible and visual alarm device, and an "inspection" and "patrol" gear adjustment switch, and a set of algorithms are designed on this basis. When switching to the "inspection" position, the induction electric detection device of the "inspection" gear should react more sensitively because it involves the operation of electrical equipment and the distance between the human body and the electrical equipment is relatively close; when switching to the "patrol" position, the inspection after the electrical equipment fails should follow the requirements listed in the power safety work regulations that "when high-voltage electrical equipment is grounded, indoor personnel shall not approach the fault point within 4m, and outdoor personnel shall not approach the fault point within 8m". The "patrol" gear induction electric detection device should be set for distance sensing. The difficulty lies in that the micro portable personal protection induction alarm device body is not charged, the purpose is to prevent the misjudgment of the induction electricity, but by detecting the existence of real induction electricity in the area, the induction electricity in the range is supplied to the detection device, so that the alarm device emits an audible and visual alarm, and the distance monitoring of the "patrol" gear should also be accurate and sensitive.

[0039] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The technical solutions provided by the embodiments of the present invention are described in detail below in conjunction with the drawings.

[0040] In order to better understand the purpose of the present invention, the present invention is described in further detail below.

[0041] A data acquisition module acquires historical data of the device, including historical induced electricity data, historical distance data between human body and electrical equipment, historical gear adjustment data and historical alarm triggering data, pre-processes the historical data of the device, and uses the pre-processed historical data of the device to train the model to obtain an induced electricity detection model;

[0042] The data acquisition module is first responsible for collecting the historical data of the device. These data include historical induced electrical data, historical human-electrical distance data, historical gear adjustment data, and historical alarm trigger data. These data are the basis for model training and subsequent induced electrical detection.

[0043] The collected raw data may contain noise, missing values ​​or inconsistent formats, so preprocessing is required. The preprocessing steps may include data cleaning (such as removing duplicate values, handling missing values), data transformation (such as data formatting, normalization or standardization), feature selection or feature extraction, etc.

[0044] For historical induced electrical data, it may be necessary to convert it into a format that the model can understand, such as normalizing continuous values ​​such as voltage and current.

[0045] For historical data on the distance between human bodies and electrical equipment, it may be necessary to ensure the consistency and accuracy of the data, and it may also be necessary to perform unit conversion or range limitation based on specific application scenarios.

[0046] The historical gear adjustment data reflect the working parameters of the inductive electrical detection device under different working modes, and these data are crucial for subsequent model training and parameter adjustment.

[0047] Historical alarm triggering data records the specific circumstances and conditions that triggered alarms in the past, and can provide the model with examples of when an alarm is needed.

[0048] Features useful for induced electricity detection are extracted from the preprocessed data. These features may include induced electricity intensity, distance between human body and electrical equipment, working mode (maintenance or inspection), etc.

[0049] A training data set is constructed based on the extracted features and the corresponding alarm triggering conditions, and a label is assigned to each sample (such as "real induced electricity exists" or "real induced electricity does not exist").

[0050] Choose an appropriate machine learning model for training, such as random forest, etc. These models can learn the relationship between features and labels from the training data.

[0051] The selected model is trained using the preprocessed device historical data (i.e., training data set), and its performance on the training data is optimized by adjusting the model parameters.

[0052] The trained inductive electrical detection model is deployed into a miniature portable personal protection inductive alarm device.

[0053] Use some historical data that was not involved in training or newly collected data to verify the model and improve the accuracy of the model in practical applications.

[0054] The induction electricity detection module collects the induction electricity data in the inspection area, substitutes the induction electricity data in the inspection area into the induction electricity detection model, outputs the induction electricity detection result in the inspection area, and if there is induction electricity in the inspection area, the induction electricity in the inspection area is supplied to the detection device;

[0055] After the induction electricity detection module is started, it starts to collect the induction electricity data in the inspection area in real time. These data may include voltage, current intensity and other electrical parameters, which are important bases for judging whether there is induction electricity in the area.

[0056] The collected induction electrical data is preliminarily processed to ensure that the data format is consistent with the input format required by the induction electrical detection model. This may include steps such as data formatting, outlier processing, and data smoothing.

[0057] The pre-processed induction electricity data is input into the pre-trained induction electricity detection model. This model is trained based on the historical data of the device and can identify whether there is real induction electricity in the inspection area.

[0058] The model calculates and analyzes the input data and outputs the results of the induction electricity detection in the inspection area. This result is a judgment indicating whether there is induction electricity in the area.

[0059] If there is induced electricity in the inspection area, the induced electricity detection module supplies the induced electricity in the inspection area to the detection device for further analysis or processing.

[0060] At the same time, the induction electricity detection module may also transmit the detection results to other modules (such as a data processing module or an audio-visual alarm module) so that corresponding safety measures or alarm operations can be taken.

[0061] The inductive electrical detection module continuously collects inductive electrical data within the inspection area and updates the detection results in real time.

[0062] If a change in the state of the induced electricity is detected (such as from presence to absence, or from absence to presence), the induced electricity detection module will update the information in a timely manner and notify the relevant modules to perform corresponding processing.

[0063] The gear adjustment module is used to receive the working mode instruction, which includes maintenance and inspection, and match the preset induction electric detection gear control parameter library according to the working mode instruction to adjust the working parameters of the induction electric detection device;

[0064] Data processing flow of the gear adjustment module:

[0065] The gear adjustment module first receives the working mode instruction from the system or the user. This instruction clearly points out the current working mode, that is, "maintenance" or "inspection".

[0066] The gear adjustment module analyzes the working mode instruction and determines which working mode the induction electric detection device needs to be adjusted to at present.

[0067] According to the analyzed working mode, the gear adjustment module matches in a preset inductive electric detection gear control parameter library. This parameter library pre-stores the working parameters required by the inductive electric detection device under different working modes.

[0068] After matching the corresponding working mode, the gear adjustment module obtains the corresponding working parameters from the control parameter library. These parameters may include sensing sensitivity, detection range, etc., to ensure that the induction electrical detection device can work normally in different working modes.

[0069] The gear adjustment module sends the acquired working parameters to the inductive electrical detection device, which instructs the inductive electrical detection device to adjust its working state to adapt to the current working mode.

[0070] The gear adjustment module confirms that the inductive electrical detection device has successfully received and adjusted the working parameters. This can be verified through communication with the inductive electrical detection device to ensure the correctness and effectiveness of the parameter adjustment.

[0071] Finally, the gear adjustment module feeds back the result of parameter adjustment to the system or user, which helps the system or user understand the current working mode and the working status of the induction electrical detection device.

[0072] Through the above steps, the gear adjustment module can flexibly adjust the working parameters of the inductive electrical detection device according to the working mode instructions, ensuring that it can work effectively in different working environments, thereby improving the work efficiency of the operation and maintenance personnel.

[0073] The data processing module receives the data from the induction electricity detection device, processes the data according to the working mode instruction of the gear adjustment module, and determines whether there is real induction electricity through a preset data processing algorithm;

[0074] The data processing module first receives data from the inductive electrical detection device. These data are the inductive electrical data collected by the inductive electrical detection device in real time in the inspection area, which may include electrical parameters such as voltage and current intensity. At the same time, the data processing module also receives the working mode instruction from the gear adjustment module. This instruction indicates the current working mode, that is, "maintenance" or "inspection", which will affect the subsequent data processing algorithm selection.

[0075] According to the received working mode instruction, the data processing module pre-processes the data provided by the induction power detection device. The pre-processing step may include data cleaning (such as noise removal, outlier processing), format conversion, etc., to ensure data quality and meet subsequent processing requirements.

[0076] The data processing module selects a suitable data processing algorithm from a preset data processing algorithm library. These algorithms are pre-set according to the requirements of different working modes, aiming to extract useful information from the pre-processed data and determine whether there is real induced electricity.

[0077] For the "maintenance" mode, a more sensitive algorithm may be selected to quickly respond to possible induced electrical risks; while for the "patrol" mode, more emphasis may be placed on data stability and accuracy.

[0078] Apply the selected data processing algorithm to conduct in-depth analysis on the pre-processed data. The algorithm will calculate and analyze the electrical parameters in the data to determine whether there is a real induced electrical signal.

[0079] If the algorithm determines that there is real induced electricity, the data processing module will prepare to trigger the alarm process; if there is no real induced electricity, it will continue to monitor and receive new induced electricity data.

[0080] The data processing module outputs the analysis results to the sound and light alarm module and other related components. If the judgment result is that there is real induced electricity, the sound and light alarm module will respond and send out a sound and light alarm signal.

[0081] At the same time, the data processing module may also record the analysis results in the system log for subsequent analysis and tracking.

[0082] Through the above process, the data processing module can effectively process and analyze the data provided by the induced electricity detection device, accurately determine whether there is real induced electricity, and trigger the alarm mechanism in time to ensure the safety of operation and maintenance personnel.

[0083] The sound and light alarm module, when the working mode instruction is in patrol inspection, the induction electricity detection module detects real induction electricity or the distance between the human body and the electrical equipment is too close, and the data processing module determines whether there is real induction electricity, the sound and light alarm device responds and sends out a sound and light alarm.

[0084] The working process of the sound and light alarm module:

[0085] The sound and light alarm module first receives the working mode instruction from the gear adjustment module to confirm whether the current device is in the "patrol" mode. Only in the "patrol" mode will the sound and light alarm module decide whether to trigger the alarm based on the induction electrical detection results and the distance data between the human body and the electrical equipment.

[0086] When the device is in the "patrol" mode, the sound and light alarm module receives the induction electricity detection results in the patrol area from the induction electricity detection module. These results include information on whether there is real induction electricity.

[0087] If the micro portable personal protection sensing alarm device has a distance detection function, the sound and light alarm module will also receive real-time distance data between the human body and the electrical equipment.

[0088] The sound and light alarm module receives the processing result of the induced electricity detection data from the data processing module, that is, determines whether there is real induced electricity.

[0089] The sound and light alarm module combines the induction electricity detection results, distance data (if available) and data processing results to determine whether the alarm triggering conditions are met. Specifically, if the induction electricity detection module detects real induction electricity, or the distance between the human body and the electrical equipment is too close (if the device has a distance detection function), and the data processing module also confirms the existence of real induction electricity, then the alarm triggering conditions are met.

[0090] When the alarm triggering conditions are met, the sound and light alarm module will immediately respond and send out sound and light alarm signals. The sound and light alarm signals are designed to quickly attract the attention of people around and alert them to potential safety risks.

[0091] The sound and light alarm module also records the alarm event in the log. The alarm event information may include detailed information such as the alarm time, induction alarm, too close distance alarm (if applicable), and alarm duration. These records are of great significance for subsequent accident analysis, responsibility tracing, and continuous optimization of equipment performance.

[0100] The gear adjustment module receives the working mode instruction from the system, and the working mode instruction indicates the current working mode, i.e., maintenance or inspection;

[0101] After receiving the working mode instruction, the gear adjustment module analyzes the working mode. According to the analyzed working mode, the gear adjustment module matches in a preset inductive electric detection gear control parameter library. The preset inductive electric detection gear control parameter library includes working parameters required by the inductive electric detection device under different working modes. After matching the working parameters, the gear adjustment module sends these parameters to the inductive electric detection device.

[0102] The induction electric detection device adjusts the working state of the induction electric detection device according to the received parameters, and the parameters of the induction electric detection device include induction sensitivity and detection range;

[0103] After the gear adjustment module confirms that the inductive electrical detection device has successfully received and adjusted the working parameters, it feeds back the adjustment results to the system or the user.
