Description

Technical Field

[0001] The present invention relates to the technical field of intelligent monitoring and the Internet of Things, and specifically to a high-temperature grading warning method for electrical equipment based on ceramic temperature measurement. Background Art

[0002] Temperature sensors are the most direct and basic devices in the high-temperature warning of electrical equipment. In the prior art, it is usually directly installed at the key parts of electrical equipment, which can collect temperature data in real time and transmit the data to the control system for analysis.

[0003] The control system realizes the real-time monitoring and warning of the high-temperature state of electrical equipment by integrating multiple components such as a data transmission module, a data processing module, and a warning output module. The control system receives sensor data through the integrated data transmission module and uses the data processing module for analysis and judgment. When the temperature exceeds the preset threshold, the warning output module will issue an audible and visual alarm signal or a remote notification to remind relevant personnel to take measures in time.

[0004] However, the prior art has the following defects: Disadvantage 1: Temperature sensors are not suitable for extreme environments Temperature sensors are suitable for working in dry environments, usually with a narrow temperature measurement range, and need to avoid too high or too low temperatures and voltage fluctuations. After high temperature or long-term use, the performance of temperature sensors may change, and their corrosion resistance is weak, and they cannot work stably in strongly corrosive media for a long time; Disadvantage 2: There are problems of missed alarms and false alarms in high-temperature warnings Due to the fact that the control system fails to accurately capture the change of high-temperature signals in some cases, or there are errors in data processing, the situations of missed alarms and false alarms occur: 1. When the equipment reaches or exceeds the critical temperature, the warning system does not issue an alarm in time; 2. When the equipment does not reach the critical temperature, the warning system wrongly issues a high-temperature alarm; In the case of missed alarms, the equipment may be damaged due to being in a high-temperature state for a long time, and even more serious failures may be caused. Due to the failure to discover and handle in time, these potential risks may gradually accumulate and eventually cause unpredictable consequences. False alarms will cause waste of human and equipment resources. Staff may rush to the scene due to false alarms for unnecessary inspections and repairs, which will not only disrupt the normal work order, but also consume a large amount of human, material and time costs.

[0005] To this end, the present invention provides a high-temperature graded early warning method for electrical equipment based on ceramic temperature measurement. The method realizes real-time monitoring and graded early warning of the temperature of electrical equipment by installing temperature-sensitive color-changing ceramics on the electrical equipment and monitoring it with an intelligent camera integrated with an advanced recognition algorithm. This method greatly improves the safety and reliability of electrical equipment and is an indispensable part of a modern intelligent monitoring system. Summary of the invention

[0006] The purpose of the present invention is to provide a high temperature graded early warning method for electrical equipment based on ceramic temperature measurement to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-temperature graded warning method for electrical equipment based on ceramic temperature measurement, comprising a temperature measuring element, an intelligent monitoring device containing an intelligent camera, and a main control unit, wherein the temperature measuring element is a high-temperature color-changing ceramic having a unique thermosensitive color-changing property, the intelligent camera captures color changes in real time and transmits data to the main control unit, and an advanced recognition algorithm is integrated in the intelligent monitoring device. When the camera captures a change in the color of the ceramic, the system automatically triggers a warning mechanism; The method specifically comprises the following steps: Step 1. Fix the high-temperature color-changing ceramics at the key parts of the transformer or other electrical equipment to ensure that they are fully exposed to the ambient temperature; these parts are usually the bottleneck of equipment heat dissipation and the places where the temperature is most likely to rise. By installing color-changing ceramics at these parts, the temperature status of the equipment can be monitored more accurately; Step 2: Use the smart camera to monitor the color change of ceramics in real time and identify the captured images. The AI ​​recognition algorithm can accurately identify the color change of temperature-dependent ceramics and transmit the data to the main control unit. Step 3. The main control unit determines the temperature status of the equipment based on the degree of color change. The system is graded according to the color. Once it detects that the ceramic reaches the preset warning color, the system will immediately trigger a high temperature warning notification and send it to relevant personnel via wireless communication. Ensure that the notification content includes the temperature level and specific location, so that maintenance personnel can quickly locate and take corresponding measures; Step 4: After receiving the warning notification, the maintenance personnel will quickly conduct an on-site inspection, determine the temperature level based on the warning information, and take corresponding measures, such as cooling or replacing parts, to prevent further overheating of the equipment; Step 5. The system records each warning and processing situation, generates reports for management analysis, optimizes equipment operation and maintenance strategies, and improves the overall safety management level.

[0008] Preferably, in Step 3, when the smart camera detects that the color of the ceramic is white, no high temperature warning is issued.

[0009] Preferably, in Step 3, when the ceramic color is detected to be orange, a first-level warning is issued, indicating that the temperature of the equipment has increased and requires continuous attention from personnel.

[0010] Preferably, in Step 3, when the ceramic color is detected to be red, a second-level warning is issued, indicating that the equipment is in a high temperature state and needs to be handled in time.

[0011] The present invention provides a high temperature classification warning method for electrical equipment based on ceramic temperature measurement. It has the following beneficial effects: (1) The present invention adopts a ceramic material that can change color with temperature as a temperature measuring element, which is directly installed on the electrical equipment to construct a temperature sensing solution for electrical equipment. This solution can not only realize the real-time and accurate monitoring of the equipment temperature, but also significantly enhance the high temperature resistance and corrosion resistance of the temperature measuring device. During operation, it can maintain stable performance output, effectively resist the interference and influence of various adverse external factors, and ensure the continuous reliability of the temperature measurement function.

[0012] (2) The present invention can realize high-temperature graded warning, and adopts intelligent camera equipment to carry out real-time monitoring of ceramics with temperature-sensitive color-changing characteristics. The equipment integrates accurate recognition algorithms and significantly improves the accuracy of high-temperature warning through graded warning, greatly reducing the incidence of missed alarms and false alarms. Once the system detects any abnormal condition, it can quickly trigger the response mechanism to effectively prevent the occurrence of safety accidents caused by overheating of equipment.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0015] Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals designate like or similar elements or elements having like or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0016] A preferred embodiment of an electrical equipment high-temperature grading early warning method based on ceramic temperature measurement provided by the present invention is as Figure 1-3 follows: An electrical equipment high-temperature grading early warning method based on ceramic temperature measurement includes a temperature measurement element, an intelligent monitoring device containing an intelligent camera, and a main control unit. The temperature measurement element is a high-temperature discoloring ceramic, which has unique thermochromic properties. According to different ambient temperatures, the ceramic will change color. This change is not only obvious but also easily captured by the intelligent camera. The ceramic material itself has excellent high-temperature resistance and corrosion resistance. In the working environment of electrical equipment, high temperature and corrosive gases or substances are common challenges. However, this high-temperature discoloring ceramic can remain stable under these harsh conditions, will not be damaged or lose its discoloring performance due to high temperature, and is not easily eroded by corrosive substances. This makes it an ideal choice for high-temperature early warning of electrical equipment. The intelligent camera captures the color change in real time and transmits the data to the main control unit. Advanced recognition algorithms are integrated in the intelligent monitoring device. When the camera captures a change in the color of the ceramic, the system will automatically trigger the early warning mechanism. Through methods such as sound, light signals, or wireless communication, the system can quickly send high-temperature early warning notifications to relevant personnel in a graded manner. This enables equipment maintenance personnel to timely understand the high-temperature situation of the equipment and take corresponding measures for handling, thereby avoiding equipment failures and safety accidents; The method specifically includes the following steps: Step1: Fix the high-temperature discoloring ceramic at key parts of the transformer or other electrical equipment to ensure that it is fully in contact with the ambient temperature; these parts are usually the bottlenecks of equipment heat dissipation and the places where the temperature is most likely to rise. By installing the discoloring ceramic at these parts, the temperature state of the equipment can be monitored more accurately; Step2: Real-time monitor the color change of the ceramic through the intelligent camera, identify the captured images, and through the AI recognition algorithm, accurately identify the color change of the temperature-changing ceramic and transmit the data to the main control unit; Step 3. The main control unit determines the temperature status of the equipment according to the degree of color change. The system is graded according to the color. Once the ceramic is detected to reach the preset warning color, the system will immediately trigger a high temperature warning notification and send it to relevant personnel through wireless communication to ensure that the notification content contains the temperature level and specific location, so that maintenance personnel can quickly locate and take corresponding measures. For example, when the smart camera detects that the ceramic color is white, no high temperature warning is issued; when the ceramic color is detected to be orange, a first-level warning is issued, indicating that the temperature of the equipment has risen and personnel need to continue to pay attention; when the ceramic color is detected to be red, a second-level warning is issued, indicating that the equipment is in a high temperature state and needs to be handled in time; Step 4: After receiving the warning notification, the maintenance personnel will quickly conduct on-site inspections, determine the temperature level based on the warning information, and take corresponding measures, such as cooling or replacing components, to prevent further overheating of the equipment; Step 5. The system records each warning and processing situation, generates reports for management analysis, optimizes equipment operation and maintenance strategies, and improves the overall safety management level.

[0017] The graded warning system can more accurately monitor and identify different levels of high temperature conditions by setting different color thresholds. This refined management method helps to accurately judge the severity and urgency of temperature changes, so as to make more appropriate responses. For lower-level high temperature warnings, milder preventive measures can be taken; while for higher-level high temperature warnings, more urgent and comprehensive response plans can be quickly initiated. Through this reasonable graded setting, unnecessary false alarms can be reduced while ensuring that important high temperature conditions are not missed. Each level of warning has clear standards and corresponding response measures, making the entire warning system more reliable and efficient. The high temperature graded warning system issues a warning before the temperature reaches a dangerous level, thereby providing enterprises or individuals with enough time to take preventive measures, which can more reasonably allocate emergency resources and avoid or reduce the damage caused by high temperatures.

[0018] In summary, the present invention uses a unique high-temperature color-changing ceramic material as the core temperature measurement component, which can keenly sense and respond to subtle changes in ambient temperature, followed by a distinct color change. This change is intuitive and can be easily captured and recorded accurately by smart surveillance cameras; temperature-changing ceramics rely on the intuitiveness of color changes with temperature, and can quickly judge the temperature state without any additional equipment, greatly facilitating user operation and judgment. No external power supply is required, allowing it to work stably in a variety of complex or difficult-to-power-supply environments, demonstrating its high degree of autonomy and adaptability. In addition, temperature-changing ceramics also have excellent high-temperature and corrosion resistance, and can maintain stable performance in extremely harsh working environments, ensuring the accuracy and reliability of temperature monitoring; The present invention uses intelligent camera equipment to monitor ceramics with temperature-sensitive color-changing characteristics in real time. The equipment combines a high-precision recognition algorithm and implements a graded warning mechanism, which significantly improves the accuracy of high-temperature warnings and significantly reduces the probability of missed reports and false alarms. When the system detects any abnormal situation, it will immediately activate the rapid response mechanism to effectively prevent safety accidents that may be caused by overheating of the equipment; It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
