[0024] It should be understood that the order of execution of the steps in the following embodiments does not necessarily mean the order of execution, and the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
[0025] First, as Figures 1 to 5 As shown, a cable fault early warning detection system based on RFID double-fuse technology is provided, and the cable fault early warning detection system includes an RFID double-fuse tag 2, an RFID reader and a data management system.
[0026] In this embodiment, the RFID double fuse tag includes a chip, a first antenna and a low melting point metal, wherein the low melting point metal includes a first melting point metal and a second melting point metal, and the chip includes a data processing unit. As an example, the data processing unit can be connected to the first melting point metal, the second melting point metal and the antenna respectively. Specifically, the data processing unit is used to obtain the state of the first melting point metal and the second melting point metal and the current operation state of the cable 1, and the antenna is used to receive the radio frequency signal sent by the RFID reader, or send the radio frequency signal to the RFID reader. Among them, the melting point of the first melting point metal is less than the melting point of the second melting point metal. For example, the melting point of the first melting point metal can be 100°C, and the melting point of the second melting point metal can be 200°C, which is not limited here. In practical applications, the maximum allowable operating temperature of cables of different models and types is different. For example, the long-term allowable operating temperature of cables insulated with polyvinyl chloride (PVC) is generally 70°C. However, in the case of a short circuit, its maximum temperature can reach 160°C; cables insulated with cross-linked polyethylene (XLPE) have higher heat resistance, and their long-term allowable operating temperature can reach 90°C. In the case of a short circuit, its maximum temperature can reach 250°C. The scientific and reasonable selection of different low-melting-point metals improves the applicability of the cable fault early warning detection system.
[0027] The data management system includes a data receiving module, a data processing module, a data visualization module, a communication interface and an early warning module. As an example, the data receiving module is used to receive the tag information sent by the RFID reader through the communication interface and transmit it to the data processing module; the data processing module is used to parse and analyze the tag information to identify the cable status and generate analysis results; the data visualization module is used to graph the analysis results to help users intuitively understand the cable status; the early warning module generates early warning information based on the analysis results and sends it to the target account.
[0028] Further, the RFID reader is used to obtain tag information sent by the RFID double-fuse tag and send the tag information to the data management system, the tag information including the first melting point metal state and the second melting point metal state; The data management system is used to send warning information to the target account according to the first melting point metal state and the second melting point metal state.
[0029] In this embodiment, the first melting point metal state and the second melting point metal state include blown and normal. Specifically, the first melting point metal state and the second melting point metal state are determined based on the cable operation state. As an example, when the temperature of the cable reaches or exceeds the melting temperature of the corresponding first melting point metal, the first melting point metal melts, and the corresponding first melting metal state is blown.
[0030] In some embodiments, the RFID reader is used to obtain the tag information sent by the RFID double-fuse tag, and send the tag information to the data management system. The data management system is used to receive the tag information sent by the RFID reader, and parse out the first melting point metal state and the second melting point metal state in the tag information. Specifically, the data management system can decode the received tag information through its built-in processor and parsing algorithm to obtain the first melting point metal state and the second melting point metal state. As an example, the states of the first melting point metal and the second melting point metal can be respectively corresponding to different codes. For example, the first melting point metal state corresponds to the code "00" indicating unfused, and "01" indicating fused; the second melting point metal state corresponds to the code "10" indicating unfused, and "11" indicating fused. The data management system determines the first melting point metal state and the second melting point metal state based on these coded information. Further, according to the parsed states of the first melting point metal state and the second melting point metal state, an early warning message is sent to the target account. Through the above method, when the cable is overheated or fails, an early warning can be effectively provided, which is convenient for maintenance personnel to respond and handle in time to ensure the safe operation of the high-voltage cable.
[0031] The target account includes but is not limited to the user account and / or management platform account responsible for monitoring the operation status of the cable, for example, the mobile terminal account of the power system operation and maintenance personnel, the control platform account of the central monitoring room, or the early warning receiving terminal of other relevant management personnel, which can be set according to the needs of the actual application scenario to ensure that the relevant personnel or system can be notified in time in an emergency, which is not limited here. The early warning information can include but is not limited to the current RFID double-fuse tag's expiration time and / or specific location information, where the specific location can be determined using the spatial location information of the RFID double-fuse tag, the association between the various cable components (such as tags installed at the cable terminal head, middle head or other cable-dense areas) or other methods, which is not limited here. In summary, in a solution provided by an embodiment of the present invention, a cable fault early warning detection system includes an RFID double-fuse tag, an RFID reader and a data management system; the RFID reader is used to obtain the tag information sent by the RFID double-fuse tag, and send the tag information to the data management system, the tag information includes a first melting point metal state and a second melting point metal state; the data management system is used to send early warning information to the target account according to the first melting point metal state and the second melting point metal state. In this embodiment, the data management system automatically determines whether the cable has an overheating risk or a fault condition according to the first melting point metal state and the second melting point metal state in the tag information, and sends early warning information to the target account accordingly, which can promptly issue an alarm when the cable state is abnormal, reducing the potential risk of fire or power outage, improving the safety of the power system, and realizing efficient, real-time monitoring and automatic early warning of the cable.
[0032] In one embodiment, sending a warning message to a target account according to the first melting point metal state and the second melting point metal state includes: When the first melting point metal state and / or the second melting point metal state is melting, a warning message is sent to the target account; When the first melting point metal state and the second blown-melt metal state are both normal, no warning information is sent to the target account.
[0033] In this embodiment, the data management system detects whether the two metal states are normal through a preset judgment logic. Usually, the first melting point metal and the second melting point metal correspond to different temperature thresholds, and the melting point of the first melting point metal is lower than the melting point of the second melting point metal, which is used to monitor the temperature abnormality of the cable in a graded manner.
[0034] As an example, when the first melting point metal state and the second melting point metal state are both normal (i.e., neither is melted), it means that the temperature of the cable has not reached the warning threshold and the cable is in a safe operating state. Therefore, the data management system will not send warning information to the target account. This state helps to avoid excessive interference of the data management system on the normally operating cable, thereby reducing the number of unnecessary alarms.
[0035] However, when the first melting point metal state and / or the second melting point metal state is melted, it means that the cable temperature has exceeded the set safety threshold, and the cable may be at risk of overheating or has failed. In this case, the data management system will immediately send an early warning message to the target account to remind the operation and maintenance personnel or the management system to take necessary maintenance or repair measures. The early warning information may include details such as the specific cable location, the state of the melting metal, and the melting time, helping the operation and maintenance personnel to locate the problem in a timely and accurate manner and prevent the accident from further expanding.
[0036] In one embodiment, the warning information includes cable overtemperature information, fault information and tag fault information. When the first melting point metal state and / or the second melting point metal state is melting, the warning information is sent to the target account, including: When the first melting point metal is in the state of being melted, a cable over-temperature message is sent to the target account; When the first melting point metal state and the second melting point metal state are both melting, a cable fault message is sent to the target account; When the second fuse metal state is blown, a tag fault message is sent to the target account.
[0037] In this embodiment, when the data management system determines that the state of the first melting point metal is "fused", it indicates that the temperature of the cable has exceeded the melting point of the first melting point metal, and the data management system sends "cable overtemperature information" to the target account, indicating that the cable may have insulation aging, poor contact, discharge, etc., and reminds the user to check. The cable overtemperature information sent to the user can be displayed to the user in the form of a chart or dashboard.
[0038] If the data management system determines that the states of the first melting point metal and the second melting point metal are both "fused", this indicates that the temperature of the cable has abnormally risen to a level sufficient to melt the two melting point metals. At this time, the data management system sends "cable fault information" to the target account. This information indicates that the cable may have failed and needs to be repaired or replaced immediately to prevent power outages. The cable fault information sent to the user can also be displayed to the user in the form of a chart or dashboard.
[0039] When the data management system determines that the state of the second melting point metal is "blown" and the state of the first melting point metal is normal, the data management system sends "tag failure information" to the target account. This situation may indicate that the RFID tag itself is faulty or has a reading error, and the user needs to check or replace the tag. The tag failure information sent to the user can also be displayed to the user in the form of a chart or dashboard.
[0040] For example, a key position of the cable is equipped with an RFID double-fuse tag. Assume that the first melting point metal at this position is set to 150°C and the second melting point metal is set to 200°C. Under normal circumstances, both metals should remain in an unfused state.
[0041] Case 1: Normal state After the RFID reader obtains the tag information, it finds that the first melting point metal state and the second melting point metal state are both "normal". This indicates that the temperature of the cable is below 150°C, far from the melting point of 200°C. Therefore, the data management system will not send an early warning message to the target account. In this case, the operation status of the cable is normal and monitoring will continue without interference.
[0042] Case 2: The first melting point metal state is melted Assume that the temperature of the cable reaches 160°C, causing the first melting point metal to melt. At this time, the RFID reader will receive the tag information showing that the first melting point metal is "melted", but the second melting point metal is still "normal". The data management system will send "cable overtemperature information" to the target account based on this status.
[0043] Case 3: Both the first melting point metal state and the second melting point metal state are melted If the temperature of the cable further rises to 210°C, exceeding the melting point of the second melting point metal, both the first melting point metal state and the second melting point metal state will be fused. In this case, the data management system will send "cable fault information" to the target account. This information can not only include the specific location and fusing time of the cable, but also a detailed description of the serious fault of the cable to prevent risks such as cable damage or fire.
[0044] Case 4: The second melting point metal state is melted If the second melting point metal melts, while the first melting point metal is still normal, this may indicate that there is a problem with the RFID tag during reading, for example, a tag failure. At this time, the data management system will send a "tag failure message" to the target account to remind the operator to check the status of the RFID tag to ensure the overall monitoring effect of the system.
[0045] In one embodiment, the RFID reader is used to obtain tag information sent by the RFID double-fuse tag, including: The RFID reader is used to transmit a first radio frequency signal to the RFID double-fuse tag; After receiving the first radio frequency signal, the RFID double-fuse tag starts to collect the running status of the cable, generates tag information, and returns the tag information to the RFID reader through the second radio frequency signal.
[0046] In this embodiment, the RFID reader includes a transmitting module, a receiving module, a processor, an antenna and a power module. As an example, the transmitting module is used to generate a first radio frequency signal of a specific frequency, and send the radio frequency signal to the RFID double-fuse tag through the second antenna. After receiving the first radio frequency signal sent by the transmitting module, the RFID double-fuse tag begins to enter the operation state of the acquisition cable, and generates tag information, and further converts the tag information into a second radio frequency signal, and transmits it back to the receiving module of the RFID reader through the first antenna. The receiving module is used to receive the second radio frequency signal returned by the RFID double-fuse tag, and convert the second radio frequency signal into a processable electrical signal to obtain the tag information sent by the RFID double-fuse tag. Among them, the power module provides the necessary power for each component of the RFID reader.
[0047] In one embodiment, an RFID reader is used to obtain tag information sent by an RFID double-fuse tag and send the tag information to a data management system, including: When the RFID reader fails to obtain the tag information, an early warning message is sent to the target account.
[0048] In this embodiment, in some cases, the RFID reader may fail to obtain the tag information sent by the RFID double-fuse tag. This situation usually indicates that the RFID double-fuse tag may have expired, or there is a communication problem between the RFID reader and the tag. More seriously, this situation may indicate that the cable at the RFID double-fuse tag has been damaged or failed. To ensure the safety and stability of the cable, when the RFID reader fails to successfully obtain the tag information, the data management system will automatically send an early warning message to the target account based on the situation where the tag information is not obtained, to remind relevant personnel to check the cables in the area. Possible faults or damage problems need to be dealt with in a timely manner to prevent potential safety hazards or further cable failures.
[0049] In one embodiment, if Figures 1 to 5 As shown, the cable fault early warning detection system also includes an intelligent robot 3 and a circular track 4; The circular track is set in the cable trench where the cables are located, and the intelligent robot runs along the circular track; The RFID reader is installed on the intelligent robot, which drives the RFID reader to move along the circular track according to the control instructions sent by the data management system to realize automatic inspection of the cable; The control instructions include a preset inspection time interval and inspection frequency.
[0050] In this embodiment, the circular track is arranged in the cable trench where the cable is located to ensure that the intelligent robot can move smoothly in the narrow space in the cable trench. The design of the circular track allows the intelligent robot to repeatedly run within a certain range, thereby covering all detection points of the cable.
[0051] The intelligent robot is arranged on a circular track, and an RFID reader is arranged on it, for example, it can be arranged on the head or both sides of the intelligent robot, which is not limited here. The function of the RFID reader is to obtain the tag information sent by the RFID double-fuse tag, and the tag information is used to monitor the status and temperature of the cable. According to the control instructions sent by the data management system, including the preset inspection time interval and inspection frequency, the intelligent robot automatically inspects the cables in turn along the circular track. For example, the intelligent robot is instructed to inspect once every hour, and must pass through all areas of the cable trench in each inspection. After receiving these control instructions, the intelligent robot will automatically start to inspect along the circular track according to the set time interval and frequency. When the intelligent robot moves along the circular track, the RFID reader will scan the RFID double-fuse tags on the cables passing by in real time, obtain the tag information, and transmit the tag information to the data management system. The data management system analyzes the received information, monitors the status of the cable in real time, and ensures that potential faults or abnormal conditions are discovered in time. Among them, through the combination of the intelligent robot and the circular track, the automatic and systematic inspection of the cable is realized, which greatly reduces the workload of manual inspection and improves the inspection efficiency, coverage and accuracy. In addition, automated inspections can continuously monitor cable status at specified time intervals, thereby promptly identifying problems and taking corresponding measures, further improving the safety and stability of the power system.
[0052] In one embodiment, the label information also includes operation information of key parts of the cable, and the data management system is further used for: Input the operation information into the AI big model to obtain the analysis results output by the AI big model, which include the remaining service life of the key parts of the cable, the time of potential fault occurrence and the severity of the fault; Among them, the AI big model is trained based on the historical operation information and degradation trend data of similar key parts of the cable.
[0053] In this embodiment, the key parts of the cable include the terminal head, the middle head and the dense area of the cable; the operation information of the key parts of the cable includes the temperature, load condition, operating environment, service life and the status of the RFID double fuse tag at the key parts. The data management system inputs the acquired operation information into the AI big model, and the AI big model processes the input operation information and outputs the analysis results, including the remaining service life of the key parts of the cable, the potential fault occurrence time and the fault severity. For example, the remaining service life of the terminal head of the AI big model is 6 months, the expected fault occurrence time is 3 months later, and the current fault severity is medium. These prediction results help maintenance personnel take measures in advance to carry out necessary maintenance and replacement to avoid sudden failure of the cable, provide accurate fault warning and maintenance suggestions, greatly improve the intelligence level of cable management and the accuracy of warning, and ensure the stable operation of the power system. Among them, the AI big model has been established through the training of historical operation data and degradation trend data. As an example, the historical operation data includes the temperature changes, load history and fault records of the key parts of the same type of cable in actual applications, and the degradation trend data includes the mode and speed of cable degradation during use.
[0054] For example, the temperature of the terminal head is 85°C, the load current is 150A, and no fuse signal is detected. Next, these operating information are input into the AI big model, which analyzes the input real-time operating information and generates analysis results. For example, based on the current temperature and load information, the AI big model predicts that the remaining service life of the cable terminal head is 12 months, the expected potential failure time is 8 months later, and the current fault severity is low. It should be noted that the above is only an example and does not constitute a limitation of the present invention.
[0055] In one embodiment, the cable fault early warning detection system includes a plurality of RFID double-fuse tags, which are arranged at equal intervals at different positions of the cable and / or key positions of the cable.
[0056] In this embodiment, multiple RFID double-fuse tags are deployed at equal intervals at different locations of the cable and / or key locations of the cable, such as the middle joints and terminal heads of the cable where failures or overheating may occur. Each RFID double-fuse tag monitors the temperature status of the location in real time, and regularly reads and transmits the tag information to the data management system through an RFID reader, thereby realizing automatic monitoring and early warning of the cable.
[0057] Second, as Figure 6As shown, a cable fault early warning detection method based on RFID double fuse technology is provided, which is applied to the cable fault early warning detection system based on RFID double fuse technology described in the first aspect above, wherein the cable fault early warning detection system comprises a plurality of RFID double fuse tags 2, an RFID reader / writer, an intelligent robot 3 and a circular track 4, and the method comprises the following steps: S10, obtaining tag information of an RFID double-fuse tag, the tag information including a first melting point metal state and a second melting point metal state; S20. Sending warning information to a target account according to the first melting point metal state and the second melting point metal state.
[0058] In summary, in a solution provided by an embodiment of the present invention, the method includes: obtaining tag information of an RFID double-fuse tag, the tag information including a first melting point metal state and a second melting point metal state; sending an early warning message to a target account according to the first melting point metal state and the second melting point metal state. In this embodiment, based on the first melting point metal state and the second melting point metal state in the tag information, it is automatically determined whether the cable has an overheating risk or a fault condition, and an early warning message is sent to the target account accordingly, so that an alarm can be issued in time when the cable state is abnormal, reducing the potential risk of fire or power outage, and improving the safety of the power system.
[0059] In one embodiment, step S20, that is, sending a warning message to a target account according to the first melting point metal state and the second melting point metal state, includes the following steps: S21.
