Description

Technical Field

[0001] This invention relates to the field of power equipment inspection technology, and in particular to an inspection device for teaching and inspection purposes. Background Technology

[0002] Electricity goes through stages such as power generation, transmission, and distribution from production to use. Significant energy loss occurs during transportation, and potential hazards exist, such as weather conditions, which can lead to material losses. Therefore, minimizing energy loss while ensuring the reliability and security of the power grid makes regular inspections a top priority for power personnel.

[0003] Traditional power line inspection methods suffer from drawbacks such as high labor intensity, low work efficiency, fragmented inspection quality, and limited methods. Furthermore, data from manual inspections cannot be accurately and promptly integrated into the management information system.

[0004] Furthermore, power companies have very high requirements for employee skills because many work positions involve certain dangers. If power company employees are not skilled enough, it may lead to power accidents and affect the stability of power operation. Therefore, it is necessary to continuously carry out employee training to comprehensively improve the overall level and strength of power employees, ensure the stable operation of power transmission, and ensure the safety of life and equipment. Power inspection, power maintenance, and the education and training of new trainees are important components of safe production.

[0005] In the prior art, VR equipment / systems used for power training, such as VR systems for high-voltage substation simulation training (e.g., CN112991506B A VR-based high-voltage substation simulation training operating system), typically have the following problems:

[0006] 1. VR devices provide a completely virtual three-dimensional space, and the gap between virtual images and actual scenes can lead to a decrease in the learning efficiency of trainees.

[0007] 2. The system cannot achieve human-computer interaction and cannot select and control the images presented by the system according to the actual needs or learning direction of the trainees. Summary of the Invention

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions and features of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0070] Example 1

[0071] This invention provides an inspection device for teaching and patrol purposes, such as... Figure 1 , Figure 2 As shown, it includes:

[0072] AR frame 1, AR display lens 9 and interactive ring 15. AR frame 1 is equipped with power module 3 and health monitoring device. AR frame 1 is also equipped with audio device. On both sides of AR display lens 9, AR frame 1 is equipped with control signal monitoring device, visual tracking camera 8 and video interactive camera 14.

[0073] Preferably, the control signal monitoring device includes:

[0074] Visible light detection cameras 12, microphones 10, and feature points 19 are included. Two visible light detection cameras 12 are mounted on the AR frame 1, and the two visible light detection cameras 12 are located on the left and right sides of the AR display lens 9, respectively. The microphone 10 is fixedly connected to the temple on the side of the AR frame 1 via a conduit. The feature points 19 are irregularly arranged on the main interface of the interactive ring 15. The feature points 19 are controlled to light up by the feature diode module 28. The main interface of the interactive ring 15 also has an OLED display screen 20 and a ring switch button 21. An interactive button 18 is provided on the side of the interactive ring 15.

[0075] The working principle and beneficial effects of the above technical solution are as follows:

[0076] The visible light detection camera 12 can identify feature points 19 on the interactive ring 15. When an employee wears the interactive ring 15 and makes a corresponding interactive action, appearing in the AR glasses' field of vision, the visible light detection camera 12 transmits the current position of the interactive ring 15 and the action of the interactive button 18 to the processing module. After processing, the output analog signal is converted into a digital signal and then transmitted to the AR display module. At this time, the employee can control the display mode of the virtual image in the AR display lens 9. In actual use, a guide line will appear in the direction pointed by the interactive ring 15 seen in the AR display lens 9, making it convenient for the employee to select the content displayed by the AR glasses. For example, when the interactive ring 15 is moved to control the guide line in the AR display lens 9 to move to the inspection equipment and the interactive button 18 is clicked, the AR display lens 9 will display detailed information such as the relevant parameters, internal structure, and precautions of the equipment. When the employee wears the interactive ring 15 and presses and slides the interactive button 18 upwards, the displayed virtual image will be magnified.

[0077] By controlling the signal monitoring device, the interaction between the staff and AR technology can be realized. Through the movement of the interactive ring 15, the staff can control the level of detail of the equipment instructions and the structure of any component displayed in the AR display lens 9 according to their own preferences and their understanding of the inspection equipment. Whether for training or inspection, this will improve the work efficiency of the staff.

[0078] The present invention solves the following problems raised in the background art: In the prior art, VR systems used for high voltage substation simulation training (such as CN112991506B A VR-based high voltage substation simulation training operating system) usually have the following problems: the system cannot realize human-computer interaction and cannot select and control the images presented by the system according to the actual needs or learning direction of the trainees.

[0079] Example 2

[0080] Based on Example 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the health monitoring device includes:

[0081] Electrode patch 7, emitter 16 and receiver 17 are installed on the ear rest of AR frame 1. Emitter 16 is located directly above the inner wall of interactive ring 15 and receiver 17 is located directly below the inner wall of interactive ring 15. Emitter 16 and receiver 17 are electrically connected through ring monitoring module.

[0082] Preferably, the audio device includes:

[0083] The device includes an earphone 6, a speaker hole 4, and a video interactive camera 14. The earphone 6 is embedded in the earphone slot 2, which is fixed to the temple on the side of the AR frame 1. An AR glasses switch button 5 is provided on the side of the earphone slot 2 near the AR display lens 9. A speaker hole 4 is provided between the AR glasses switch button 5 and the AR display lens 9.

[0084] The working principle and beneficial effects of the above technical solution are as follows:

[0085] The health monitoring device consists of two parts: one part is the electrode patch 7 installed on the ear cup of the AR frame 1, and the other part is installed on the inside of the interactive ring 15. The two parts complement each other. The electrode patch 7 is actually a collection of multiple sensors used to receive physiological signals from the wearer's body and has the function of monitoring the wearer's blood pressure, heart rate, etc.

[0086] By calibrating the health data of two parts of the worker's body, errors in the detection or environmental influences can be avoided, thus preventing the worker from misjudging their current physical condition. The electrode patch 7 is actually a collection of multiple sensors used to receive physiological signals from the wearer's body, and has functions such as monitoring the worker's blood pressure and heart rate. The emitter 16 and receiver 17 measure the absorption rate of light during the capillary pulsation at the point where the worker wears the interactive ring 15, thereby monitoring the human body's blood oxygen saturation, heart rate, and other functions. At the same time, the physical condition data obtained by the health monitoring device will also be displayed on the AR display lens 9. If the data is abnormal, an alarm will be issued through the audio device.

[0087] By installing health monitoring devices, staff can avoid accidents caused by hypoxia, overwork, and abnormal heart rate. The AR glasses also have a GPS positioning module, which allows monitoring personnel to know the real-time location of staff on site, thus maximizing staff safety.

[0088] Example 3

[0089] Based on any one of Examples 1-2, such as Figure 1 , Figure 5 , Figure 6 As shown, it also includes an automatic monitoring and identification system, which includes:

[0090] The identification module is used to identify equipment to be identified during power inspections; such equipment includes transformers, frequency converters, and high and low voltage switchgear.

[0091] The control signal monitoring module is used to monitor the position of the interactive ring and the voice signals emitted by the staff.

[0092] The health monitoring module is used to monitor the staff's monitoring status parameters, including heart rate, blood pressure, and blood oxygen saturation.

[0093] The processing module is electrically connected to the recognition module, the control signal monitoring module, and the AR display module. Its function is to generate a first display parameter based on input data from the recognition module, a second display parameter based on input data from the control signal monitoring module, and a third display parameter based on input data from the health monitoring module. It then analyzes and processes these three parameters, transmitting the digital signals to the analog-to-digital signal conversion module. The analog-to-digital signal conversion module converts the analog signals into digital signals and outputs the digital signals to the AR display module. The AR display module then displays relevant device descriptions and the user's own health status on the AR display lens 9 based on the input digital signals.

[0094] Preferably, the identification module includes:

[0095] The image acquisition unit is used to acquire images of the equipment to be identified during power line inspection.

[0096] An image preprocessing unit is used to preprocess the image of the device to be identified acquired by the image acquisition unit;

[0097] The image feature extraction unit is used to extract features from the image of the device to be identified in the power inspection work after the image preprocessing unit. The most basic feature of the device to be identified is its outline. The set of pixels with drastic changes in gray level around the device in the image of the device to be identified is connected to form an outline according to a certain strategy, thereby forming a segmented region. The image feature extraction unit also extracts basic features such as brightness value, texture and color in the image of the device to be identified.

[0098] The feature finding unit searches for models in the micro SD card database inserted in the card slot 11 that match each feature based on the feature simulation signal input by the image feature extraction unit. If a model exists in the database that matches the feature simulation signal input by the image feature extraction unit, the unit outputs an analog signal to the first instruction unit.

[0099] The first instruction unit outputs a first instruction signal to the processing module based on the analog signal output by the feature search unit. The first instruction signal is a high or low level signal of binary code.

[0100] Preferably, the control signal monitoring module includes:

[0101] The voice recognition unit is used to recognize the voice commands issued by the staff and output the first analog signal;

[0102] The ring status monitoring unit is used to monitor the current position of the interactive ring 15 and the action of the interactive button 18, and outputs a second analog signal;

[0103] The second instruction unit outputs a second instruction signal to the processing module based on the first analog signal and the second analog signal. The second instruction signal is a high or low level signal of binary code.

[0104] Preferably, the health monitoring module includes:

[0105] The first signal receiving unit is used to receive the third analog signal input from the electrode patch 7;

[0106] The second signal receiving unit is used to receive the fourth analog signal input to the receiving pole 17;

[0107] The difference comparison unit is used to acquire the difference signal between the third analog signal and the fourth analog signal, process the difference signal, and output it to the judgment unit.

[0108] The judgment unit is used to determine whether the difference signal exceeds the preset range. If it does not exceed the range, it transmits the third analog signal and the fourth analog signal to the signal processing unit; otherwise, it eliminates the third analog signal and the fourth analog signal.

[0109] The signal processing unit is used to combine and process the third analog signal and the fourth analog signal and then output the combined analog signal to the third instruction unit.

[0110] The third instruction unit is used to send a third instruction signal to the processing module based on the merged analog signal. The third instruction signal is a high or low level signal of binary code.

[0111] Preferably, the processing module includes:

[0112] The instruction receiving unit is used to receive the first instruction signal, the second instruction signal, and the third instruction signal, and to transmit the first instruction signal, the second instruction signal, and the third instruction signal to the data analysis and processing unit.

[0113] The data analysis and processing unit is used to analyze and process the analog signal output by the feature finding unit when it receives the first instruction signal, and output a fifth analog signal containing the features of the actual object; the data analysis and processing unit is also used to analyze and process the second analog signal output by the ring state detection unit and the first analog signal output by the speech recognition unit when it receives the second instruction signal, and output a sixth analog signal containing the ring movement state and speech features; the data analysis and processing unit is also used to analyze and process the health parameters output by the signal processing unit when it receives the third instruction signal, and output a seventh analog signal containing the current health characteristics of the staff.

[0114] The modeling unit analyzes the outline, color, and brightness features of the identified equipment based on the fifth analog signal containing the features of the actual object, creates relevant electrical equipment components with the outline, color, and brightness features of the identified equipment, and then assembles them into a physical model of the equipment containing all the features of the identified equipment, and outputs the analog signal of the physical model.

[0115] The positioning unit is used to locate the device to be identified. Based on the analog signal of the device entity model, it combines the coordinates of the device entity model with the actual location coordinates of the device. After superimposing the actual outline of the device with the device entity model, it outputs the eighth analog signal of the model to the AR display unit.

[0116] The AR command unit outputs command signals to the AR glasses based on the sixth, seventh, and eighth analog signals.

[0117] The working principle and beneficial effects of the above technical solution are as follows:

[0118] When staff wear AR glasses and the interactive ring 15 and move around the work area, electrical equipment entering the field of view of the AR display lens 9 will be automatically captured by the recognition module. After analysis and processing by the processing module, detailed parameters, internal structure, and inspection points of the electrical equipment will be projected onto the AR display lens 9. By setting up a voice recognition unit, staff can issue simple voice commands to control the AR glasses to close, flip pages, and provide explanations of relevant information about the recognized electrical equipment. For example, when a staff member issues the voice command "Detailed explanation of common-emitter amplifier circuit", the processing module will receive a second command signal from the control signal monitoring module. After the data analysis and processing unit inside the processing module analyzes and recognizes the command signal, it will control the AR glasses to generate a new window to display the detailed explanation of "common-emitter amplifier circuit" through the AR command unit. In addition, through the modeling and positioning units within the processing module, a physical model of the relevant electrical equipment appearing in the field of view of the AR glasses can be accurately generated, and the position of the electrical equipment information displayed on the AR display lens 9 can be adjusted in real time according to the relative position of the staff and the electrical equipment. This avoids the situation where the real scene and the virtual model are misaligned due to the staff moving or rotating, making the staff more comfortable to wear AR glasses.

[0119] The automatic monitoring and identification system can place staff in a work environment that combines virtual and reality, increasing their immersive experience, improving inspection efficiency, and reducing the occurrence of safety accidents.

[0120] The present invention addresses the following problems raised in the background art: In the prior art, VR systems used for high-voltage substation simulation training (such as CN112991506B, a VR-based high-voltage substation simulation training operating system) typically have the following problems: VR devices provide a completely virtualized three-dimensional space, and the gap between the virtual image and the actual scene will lead to a decrease in the learning efficiency of trainees.

[0121] Example 4

[0122] Preferably, the AR glasses also include a Bluetooth module, a WIFI module, and a voice recognition module. The WIFI module is selected as the ESP8266WIFI module, and the voice recognition module consists of a microphone and an audio signal processing module.

[0123] The beneficial effects of the above technical solution are as follows:

[0124] By setting up a Bluetooth module, 15 AR glasses of the interactive ring can be wirelessly connected, making it convenient for staff to work. Setting up a WIFI module, together with AR display lens 9, microphone 10 and earphone 6, can realize the function of visual intercom. For example, firstly, the staff inputs the voice command "call XX" through the voice recognition module. After the audio signal is recognized, the AR chip calls the relevant personnel through the WIFI module. After the other party answers, the image will be displayed on the AR display lens 9 through the AR display module, thereby achieving the purpose of visual intercom.

[0149] The working principle and beneficial effects of the above technical solution are as follows:

[0150] The interactive ring 15 incorporates a built-in health monitoring module, which includes an LED constant current drive module 25. By using this module, the LEDs are protected from burning out due to reduced resistance caused by heat generation within the interactive ring 15. Furthermore, the LED constant current drive module 25 ensures the stability of the current flowing through the diode at the emitter 16, preventing fluctuations and achieving the desired brightness. This significantly guarantees the accuracy of the health data monitored by the module. The emitter 16 of the LED constant current drive module 25 consists of two light-emitting diodes with specific wavelengths, and the receiver 17 consists of a photodiode. The health monitoring module amplifies the analog signal of the worker's blood oxygen saturation and converts it into a digital signal, which is then transmitted to the processing module of the AR glasses. Simultaneously, it... The LED module 28 is used to light up the LED at the feature point 19, enabling the visible light detection camera 12 of the AR glasses to accurately identify the position of the interactive ring 15. An interactive button module 29 is also provided. When the staff presses the button, a digital signal is generated and transmitted to the processing module of the AR glasses, thereby realizing the purpose of human-computer interaction. This allows the staff to carry out inspection work according to their own preferences and habits. An OLED display screen is set on the front of the interactive ring 15. The advantage of OLED screens over LED screens is that they can emit light themselves, so they do not need a backlight. It uses a very thin organic material coating and a glass substrate. When current passes through, the organic material will emit light. This avoids the situation where the staff cannot immediately observe the information such as battery level and signal strength on the display screen of the interactive ring 15 when they are in a dark working environment.
