Description

Technical Field

[0001] This invention relates to the field of power equipment monitoring technology, and in particular to a configuration method based on parameter coding and a transformer temperature controller. Background Technology

[0002] As a core piece of equipment in the power system, transformers generate heat in key components such as windings and cores during operation. The temperature of these components directly affects the insulation aging rate, operational safety, and service life of the transformer. Therefore, transformer temperature controllers are crucial devices for ensuring the safe and stable operation of transformers.

[0003] Existing transformer temperature controllers mostly adopt a fixed configuration design, meaning that a single temperature controller is developed only for a specific type of sensor and a specific monitoring function. This design has significant drawbacks: when users need to expand monitoring requirements, such as adding NTC thermistor temperature measurement, ambient humidity monitoring, or fan fault diagnosis via CT current transformers, the entire temperature controller hardware must be replaced, or specialized technicians must reconfigure it through complex and cumbersome modifications to low-level software parameters. This results in extremely poor adaptability of the temperature controller, failing to meet the diverse and customized equipment monitoring needs of power systems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a configuration method and a transformer temperature controller that can achieve multiple sensor adaptation and complex control requirements through simple operation.

[0005] To solve the above-mentioned technical problems, the first technical solution adopted by the present invention is as follows: A configuration method based on parameter encoding includes the following steps: S1. Establish coding configuration rules, predefine multiple codes, and associate each code with a configuration set, wherein the configuration set includes at least display control identifier, sensor type and function classification; S2, Receive the target code assigned to the physical input channel; S3. Based on the target code, find and determine the configuration set associated with the target code from the encoding configuration rules; S4. Based on the sensor types in the configuration set determined in step S3, the original electrical signals of the sensors connected to the physical input channel are collected and converted to obtain physical quantity measurement values. S5. Based on the display control identifier in the configuration set determined in step S3, perform display decision processing on the physical quantity measurement values ​​obtained in step S4. Based on the functional classification in the configuration set determined in step S3, the physical quantity measurement values ​​obtained in step S4 are logically judged and processed, and control commands or alarm statuses are generated.

[0006] The beneficial effects of this invention are as follows: This solution establishes a correlation between codes and configuration sets, integrating key configuration elements such as display control identifiers, sensor types, and functional classifications. This breaks the traditional hardware and function binding limitations of temperature controllers, allowing for rapid switching between different configurations through code selection. This enables the same device to meet diverse monitoring needs, significantly improving the product's flexibility and adaptability. Simultaneously, it standardizes the configuration process, forming a closed-loop processing mechanism from code reception, configuration lookup, signal processing to display control decisions and logical judgments.

[0008] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0009] Please refer to Figure 1 The first technical solution adopted in this invention is: A configuration method based on parameter encoding includes the following steps: S1. Establish coding configuration rules, predefine multiple codes, and associate each code with a configuration set, wherein the configuration set includes at least display control identifier, sensor type and function classification; S2, Receive the target code assigned to the physical input channel; S3. Based on the target code, find and determine the configuration set associated with the target code from the encoding configuration rules; S4. Based on the sensor types in the configuration set determined in step S3, the original electrical signals of the sensors connected to the physical input channel are collected and converted to obtain physical quantity measurement values. S5. Based on the display control identifier in the configuration set determined in step S3, perform display decision processing on the physical quantity measurement values ​​obtained in step S4. Based on the functional classification in the configuration set determined in step S3, the physical quantity measurement values ​​obtained in step S4 are logically judged and processed, and control commands or alarm statuses are generated.

[0010] As can be seen from the above description, the beneficial effects of the present invention are as follows: This solution establishes a correlation between codes and configuration sets, integrating key configuration elements such as display control identifiers, sensor types, and functional classifications. This breaks the traditional hardware and function binding limitations of temperature controllers, allowing for rapid switching between different configurations through code selection. This enables the same device to meet diverse monitoring needs, significantly improving the product's flexibility and adaptability. Simultaneously, it standardizes the configuration process, forming a closed-loop processing mechanism from code reception, configuration lookup, signal processing to display control decisions and logical judgments. This ensures the accuracy and efficiency of configuration operations and achieves automatic matching of sensor signal processing and functional logic, eliminating the need for manual intervention in underlying parameter settings, reducing the risk of operational errors, and improving the ease of use of the temperature controller.

[0011] Furthermore, the encoding in step S1 is a four-digit code, wherein the thousands digit of the code is configured to determine the display control identifier, the hundreds digit of the code is configured to determine the sensor type, and the tens and units digits of the code are configured together to determine the function classification.

[0012] As can be seen from the above description, the coding rules are concise and clear, making them easy for users to understand and remember. At the same time, the standardized coding structure is conducive to unified management and quality control in the production and manufacturing process, realizing the accurate mapping between coding and configuration elements. The corresponding configuration information can be quickly identified by different numbers of bits in the code, improving the efficiency of configuration lookup and parsing. Furthermore, sufficient space is reserved for the expansion of the coding. The coding value can be expanded on the basis of the existing coding structure according to the new sensor type or functional requirements, ensuring the compatibility and scalability of the coding system.

[0013] Furthermore, in step S5, the decision processing specifically includes the following steps: S51. Determine whether the display control indicator indicates that display is allowed; S52. If display is allowed, combine the measured value of the physical quantity and the corresponding channel identification information to generate the data to be displayed; If display is not allowed, the display processing flow for the measured physical quantity value is skipped.

[0014] As described above, this display decision processing controls whether or not to display measured values ​​based on display control identifiers. This design achieves automated management of display control logic, eliminating the need for manual configuration of display parameters and simplifying the operation process. It distinguishes between measurement data for user viewing and data for internal logic calculations, avoiding irrelevant data from occupying display resources, improving the intuitiveness and readability of the interface, while ensuring the accuracy and relevance of the displayed data. Only the key measurement values ​​needed by the user are displayed, protecting the privacy and exclusivity of the internal logic calculation data.

[0015] Furthermore, step S51 specifically includes: Read the value of the display control identifier; When the value is the first preset value, it is determined that display is allowed; When the value is a second preset value that is different from the first preset value, it is determined that the display is not allowed.

[0016] As described above, the rules for determining the display control identifier are clearly defined. By using a first preset value and a second preset value, the rules distinguish between allowed and disallowed display states. This provides a simple and clear display determination standard, enabling the microprocessor to quickly identify the encoded display attributes and improve the response speed of display decisions. It also enhances the flexibility of encoding configuration, allowing preset values ​​to be set according to actual needs (such as using the thousands digit 1 as the allowed display identifier) ​​to adapt to display requirements in different scenarios. Furthermore, it reduces the complexity of encoding parsing, enabling display state control through a single numerical determination, thus optimizing the operating efficiency of the microprocessor.

[0017] Furthermore, step S4 also includes a channel status diagnosis step, which specifically includes the following steps: The measured value of the physical quantity is compared with the preset lower limit, lower-lower limit, upper limit, and upper-upper limit of the range, respectively. The lower limit is greater than the lower-lower limit, the upper limit is greater than the lower limit, and the upper-upper limit is greater than the upper limit. If the measured value of the physical quantity is less than the preset lower limit of the range, the physical input channel is determined to be in a short-circuit state. If the measured value of the physical quantity is greater than or equal to the preset lower limit of the range and less than the preset lower limit of the range, then the physical input channel is determined to be in an over-limit state. If the measured value of the physical quantity is greater than the preset upper limit of the range and less than or equal to the preset upper limit of the range, then the physical input channel is determined to be in an over-limit state. If the measured value of the physical quantity is greater than the preset upper limit of the range, it is determined that the physical input channel is in the sensor open circuit state. Otherwise, the physical input channel is determined to be in a normal state.

[0018] As described above, a channel status diagnosis step has been added. The channel status is determined by comparing the measured value of the physical quantity with the preset range. This function enables real-time monitoring of sensor and circuit faults, and can promptly identify abnormal states such as exceeding the lower limit, exceeding the upper limit, and open circuit, providing early warning of potential risks and ensuring the safe operation of the temperature controller and transformer. It also provides maintenance personnel with accurate fault location information, facilitating quick troubleshooting of problems such as sensor damage and poor circuit contact, improving maintenance efficiency, and enhancing the reliability of the temperature controller, avoiding problems such as distorted measurement data and malfunctioning control logic caused by sensor or circuit faults.

[0019] Furthermore, the normal measurement range is set according to the functional classification, and the normal measurement range is wider than the display and alarm measurement range defined by the lower limit and the upper limit of the range.

[0020] As described above, the relationship between the normal measurement range and the display alarm range is clearly defined: the normal measurement range is wider than the display alarm range. This design provides a more reasonable judgment interval for channel status diagnosis, effectively distinguishing fluctuations within the normal measurement range from abnormal faults in sensors and circuits, thus improving the accuracy of fault diagnosis. It also avoids false alarms triggered by minor fluctuations in measured values, ensuring the stability of display and alarm functions, while ensuring that abnormal states can be captured in a timely manner. Furthermore, it provides sufficient redundancy for data measurement, adapting to slight drifts in sensor signals under different environments, and improving the stability and reliability of measurements.

[0021] Furthermore, in step S5, the measured values ​​of the physical quantities obtained in step S4 are subjected to logical judgment processing, specifically including the following steps: The measured value of the physical quantity is compared with the alarm threshold corresponding to the functional category; Based on the comparison results of the two and the predetermined control logic function, the corresponding control command or alarm status is generated.

[0022] As described above, the logical judgment process compares alarm thresholds corresponding to functional categories and generates control commands or alarm states. This design achieves precise matching between functional categories and alarm logic, with different functions corresponding to specific alarm thresholds and judgment criteria, thus improving the pertinence and accuracy of the control logic. It standardizes the logical judgment process, ensuring efficient and consistent generation of control commands and alarm states through threshold comparison and control logic function calls. Furthermore, it enhances the customization capabilities of the temperature controller, allowing for flexible configuration of alarm thresholds according to different functional requirements, thus meeting diverse monitoring and control needs.

[0023] Furthermore, the alarm thresholds include at least one of the following: fan start value, over-temperature alarm value, over-temperature trip value, humidity alarm value, and fault trigger value, and different functional categories are associated with different combinations of alarm thresholds.

[0024] As described above, the specific types and combinations of alarm thresholds are clearly defined. This design covers the core needs of transformer monitoring, including alarm settings for key parameters such as temperature, humidity, and fault detection, achieving comprehensive safety monitoring. Different functional categories are associated with different alarm threshold combinations, avoiding confusion in threshold settings, ensuring the clarity and rationality of alarm logic, and providing users with flexible threshold configuration space. Different threshold values ​​can be adjusted according to the specific operating conditions and safety requirements of the transformer, improving the adaptability of the temperature controller.

[0025] Furthermore, after generating the control command or alarm status, the following steps are also included: The corresponding relay is driven to operate according to the control command, or an audible and visual alarm is triggered and the event is recorded according to the alarm status.

[0026] As described above, by adding subsequent steps for control command execution and alarm recording, a closed-loop processing of alarm status and control commands is achieved. From logical judgment to relay action, audible and visual alarms, and event recording, a complete response mechanism is formed to ensure the effectiveness of monitoring functions. The event recording function provides an important basis for fault tracing and equipment maintenance, making it easier for maintenance personnel to analyze the cause of faults and optimize operating parameters. Moreover, the audible and visual alarms can promptly remind on-site personnel to pay attention to equipment abnormalities, and the relay action can quickly trigger protection measures (such as tripping and shutdown) to minimize fault losses.

[0027] Please refer to Figure 2 The second technical solution adopted in this invention is: A transformer temperature controller based on parameter coding, comprising: Microprocessor 1 serves as the control core; The memory 2, connected to the microprocessor 1, is used to store encoding configuration rules, configuration sets, and computer programs; Human-machine interface 3, connected to the microprocessor 1, is used to receive target codes input by the user and display information; Multiple physical input channels 4 are connected to the microprocessor 1 and are used to receive raw electrical signals from different types of sensors; Display unit 5 is connected to the microprocessor 1 and is used to display measurement values ​​and status information according to the control instructions of the microprocessor. The alarm relay output unit 6 is connected to the microprocessor 1 and is used to drive the corresponding relay to act according to the control instructions or alarm status generated by the microprocessor 1. When the computer program is executed by the microprocessor 1, it implements the above-described configuration method based on parameter encoding.

[0028] As can be seen from the above description, the beneficial effects of the present invention are as follows: By using the microprocessor 1 as the control core, it coordinates functions such as encoding parsing, signal processing, and logical judgment. The memory ensures the stable storage of configuration data and programs, and the human-machine interface 3 improves the ease of operation. Multiple configurable physical input channels 4 support the simultaneous connection of various types of sensors, enabling synchronous monitoring of multiple parameters, which improves the functional integration of the device. Moreover, the hardware structure is deeply adapted to the above configuration method, ensuring that the various functions of the encoding configuration can be stably implemented. At the same time, the hardware platform has strong versatility, eliminating the need to design dedicated hardware for different functional requirements and reducing manufacturing costs.

[0029] Please refer to Figure 1 Embodiment 1 of the present invention is as follows: A configuration method based on parameter encoding includes the following steps: S1. Establish coding configuration rules, predefine multiple codes, and associate each code with a configuration set, wherein the configuration set includes at least display control identifier, sensor type and function classification; S2, Receive the target code assigned to the physical input channel; S3. Based on the target code, find and determine the configuration set associated with the target code from the encoding configuration rules; S4. Based on the sensor types in the configuration set determined in step S3, the original electrical signals of the sensors connected to the physical input channel are collected and converted to obtain physical quantity measurement values. S5. Based on the display control identifier in the configuration set determined in step S3, perform display decision processing on the physical quantity measurement values ​​obtained in step S4. Based on the functional classification in the configuration set determined in step S3, the physical quantity measurement values ​​obtained in step S4 are logically judged and processed, and control commands or alarm statuses are generated.

[0030] The encoding in step S1 is a four-digit code. The thousands digit of the code is configured to determine the display control identifier, the hundreds digit of the code is configured to determine the sensor type, and the tens digit and the units digit of the code are configured together to determine the function category.

[0031] In step S5, the decision processing specifically includes the following steps: S51. Determine whether the display control indicator indicates that display is allowed; S52. If display is allowed, combine the measured value of the physical quantity and the corresponding channel identification information to generate the data to be displayed; If display is not allowed, the display processing flow for the measured physical quantity value is skipped.

[0032] Step S51 is as follows: Read the value of the display control identifier; When the value is the first preset value, it is determined that display is allowed; When the value is a second preset value that is different from the first preset value, it is determined that the display is not allowed.

[0033] Step S4 also includes a channel status diagnosis step, which specifically includes the following steps: The measured value of the physical quantity is compared with the preset lower limit, lower-lower limit, upper limit, and upper-upper limit of the range, respectively. The lower limit is greater than the lower-lower limit, the upper limit is greater than the lower limit, and the upper-upper limit is greater than the upper limit. If the measured value of the physical quantity is less than the preset lower limit of the range, the physical input channel is determined to be in a short-circuit state. If the measured value of the physical quantity is greater than or equal to the preset lower limit of the range and less than the preset lower limit of the range, then the physical input channel is determined to be in an over-limit state. If the measured value of the physical quantity is greater than the preset upper limit of the range and less than or equal to the preset upper limit of the range, then the physical input channel is determined to be in an over-limit state. If the measured value of the physical quantity is greater than the preset upper limit of the range, it is determined that the physical input channel is in the sensor open circuit state. Otherwise, the physical input channel is determined to be in a normal state.

[0034] The normal measurement range is set according to the functional classification, and the normal measurement range is wider than the display and alarm measurement range defined by the lower limit and the upper limit of the range.

[0035] In step S5, the measured values ​​of the physical quantities obtained in step S4 are subjected to logical judgment processing, which specifically includes the following steps: The measured value of the physical quantity is compared with the alarm threshold corresponding to the functional category; Based on the comparison results of the two and the predetermined control logic function, the corresponding control command or alarm status is generated.

[0036] The alarm thresholds include at least one of the following: fan start value, over-temperature alarm value, over-temperature trip value, humidity alarm value, and fault trigger value, and different functional categories are associated with different combinations of alarm thresholds.

[0037] After generating the control command or alarm status, the following steps are also included: The corresponding relay is driven to operate according to the control command, or an audible and visual alarm is triggered and the event is recorded according to the alarm status.

[0038] The specific implementation steps of the above-mentioned parameter-encoded configuration method are as follows: I. Preliminary Preparation Stage: (1) Constructing a coding configuration library: Establish coding configuration rules in the memory of the temperature controller, predefine multiple four-digit codes, and associate each code with a unique configuration set.

[0039] The configuration set includes display control identifiers (determined by the thousands digit, 1 for enabled display, 0 for disabled display), sensor types (determined by the hundreds digit, such as 1 corresponding to Pt100 sensor, 4 corresponding to voltage type, 5 corresponding to CT current sensor, etc.), function categories (determined by the tens and units digits, such as 01 corresponding to A1 winding temperature measurement, 02 corresponding to A2 winding temperature measurement, 01 corresponding to H1 ambient humidity monitoring, etc.), and associated parameters and logic (including ADC sampling mode, data conversion rules, measurement range (Cmin~Cmax is the display alarm range, Pmin~Pmax is the normal range), alarm thresholds, and control logic functions, etc.).

[0040] (2) Hardware connection: Connect the required sensors to the physical input channel of the temperature controller, such as connecting the Pt100 sensor to channel 1, the voltage-type humidity sensor to channel 5, and the CT current sensor to channel 8; ensure that the hardware modules such as the microprocessor, memory, human-machine interface, display unit, and alarm relay output unit are connected normally.

[0041] II. Encoding Configuration Phase: Target code reception: The user assigns target codes to each physical input channel through the human-machine interface (such as buttons, touch panel). For example, channel 1 is assigned code "1101" (representing display allowed, Pt100 sensor, A1 winding temperature measurement function), channel 5 is assigned code "1401" (representing display allowed, voltage sensor, H1 ambient humidity monitoring function), and channel 8 is assigned code "0501" (representing display not allowed, CT current sensor, fan fault detection function).

[0042] Matching Configuration Search: After receiving the target codes for each channel, the microprocessor searches the code configuration library in memory and determines the configuration set corresponding to each target code. For example, the configuration set corresponding to the code "1101" includes the display control identifier "Display Allowed", sensor type "Pt100", function category "A1 Winding Temperature Measurement", ADC sampling mode "Three-wire High-precision Sampling", data conversion rule "-40℃~200.0℃ Scale Transformation", display alarm range Cmin=-40.0℃, Cmax=200.0℃, normal range Pmin=-45.0℃, Pmax=205.0℃, alarm thresholds are winding over-temperature alarm value 130.0℃, over-temperature trip value 150.0℃, and corresponding hysteresis values, etc.

[0043] III. Signal Processing and Status Diagnosis Stage: 1. Signal Acquisition and Conversion: Based on the sensor type in the configuration set, the microprocessor calls the corresponding signal sampling and data processing module to acquire and convert the raw electrical signals of the sensors connected to the physical input channels to obtain physical quantity measurement values. For example, channel 1 enables Pt100 three-wire high-precision sampling to convert the raw electrical signal into a temperature measurement value of -40~200.0℃; channel 5 enables voltage sampling to convert the corresponding voltage signal into a humidity measurement value of 0%RH~100%RH; and channel 8 enables CT current sampling to convert the current signal into a measurement value of 0%~100%.

[0044] 2. Channel Status Diagnosis: The microprocessor compares the measured value of the physical quantity with the preset normal range (Pmin, Pmax) and the display alarm range (Cmin, Cmax) to determine the channel status. If the measured value of the physical quantity is within the range of Cmin to Cmax, it is determined to be in normal status; if the measured value of the physical quantity is greater than Pmax, it is determined that the physical input channel is in the upper limit state; if the measured value of the physical quantity is less than Pmin, it is determined that the physical input channel is in the lower limit state; if the measured value of the physical quantity exceeds the range of Pmin to Pmax, it is determined that the physical input channel is in the sensor open circuit state.

[0045] IV. Display, Control, and Logic Processing Stage: 1. Display Decision Processing: The microprocessor makes a display decision on the physical quantity measurement value based on the display control identifier (thousands digit) in the configuration set. Channel 1, with code "1101" and thousands digit 1 (display allowed), combines the temperature measurement value with the channel name "A1 winding" and sends it to the display unit for display. Channel 5, with code "1401" and thousands digit 1 (display allowed), combines the humidity measurement value with the channel name "H1 ambient humidity" and sends it to the display unit for display. Channel 8, with code "0501" and thousands digit 0 (display not allowed), skips the display processing flow, and the physical quantity measurement value is only used for internal logic calculation.

[0046] 2. Logic Judgment and Instruction Generation: Based on the functional categories in the configuration set, the microprocessor calls the corresponding alarm logic function, compares the measured physical quantity value with the associated alarm threshold, and generates control instructions or alarm status. For example, when the measured value of channel 1 (A1 winding temperature measurement) reaches 130.0℃ (over-temperature alarm value), a "winding over-temperature alarm" status is generated; when the measured value reaches 150.0℃ (over-temperature trip value), a "winding over-temperature trip" control instruction is generated. When the measured value of channel 5 (H1 ambient humidity monitoring) reaches 65.0% RH (high humidity alarm value), a "high ambient humidity alarm" status is generated. When the measured value of channel 8 (fan fault detection) exceeds the normal range (0%-100%), a "fan fault" alarm status and corresponding control instruction are generated.

[0047] V. Output and Recording Stage: 1. Output Operation: The alarm relay output unit drives the corresponding relay to operate according to the control instructions or alarm status generated by the microprocessor. At the same time, it can trigger the audible and visual alarm device (such as a buzzer or indicator light) to provide an alarm prompt. For example, when channel 1 generates the "winding over-temperature trip" command, it drives the trip relay to operate and cut off the relevant circuit; when channel 8 generates the "fan fault" status, it drives the fan fault relay to operate and prompt maintenance personnel to perform maintenance.

[0048] 2. Event logging: When the channel status changes (such as from normal to alarm, or from alarm to normal), the microprocessor records the channel's display data, relay status, and timestamp in the memory to form an operation log, which is convenient for subsequent querying and fault tracing.

[0049] VI. Cyclic Operation Phase: The temperature controller operates in a cyclical manner according to the above steps, collecting sensor signals in real time, processing data, updating the display, making logical judgments, and executing corresponding operations. Simultaneously, it continuously monitors the channel status to ensure real-time and effective monitoring of the transformer. If the user needs to adjust the configuration, the target code can be reassigned through the human-machine interface. The system will automatically repeat the above configuration and subsequent processes, enabling rapid function switching.

[0050] Please refer to Figure 2 Embodiment two of the present invention is as follows: A transformer temperature controller based on parameter coding, comprising: Microprocessor 1 serves as the control core; The memory 2, connected to the microprocessor 1, is used to store encoding configuration rules, configuration sets, and computer programs; Human-machine interface 3, connected to the microprocessor 1, is used to receive target codes input by the user and display information; Multiple physical input channels 4 are connected to the microprocessor 1 and are used to receive raw electrical signals from different types of sensors; Display unit 5 is connected to the microprocessor 1 and is used to display measurement values ​​and status information according to the control instructions of the microprocessor. The alarm relay output unit 6 is connected to the microprocessor 1 and is used to drive the corresponding relay to act according to the control instructions or alarm status generated by the microprocessor 1. When the computer program is executed by the microprocessor 1, it implements the above-described configuration method based on parameter encoding.

[0051] In summary, the present invention provides a parameter-encoded configuration method and a transformer temperature controller. By establishing an association between codes and configuration sets, it integrates key configuration elements such as display control identifiers, sensor types, and functional classifications. This breaks the traditional hardware and function binding limitations of temperature controllers, allowing for rapid switching between different configurations through code selection. This enables the same device to meet diverse monitoring needs, significantly improving the product's flexibility and adaptability. Simultaneously, it standardizes the configuration process, forming a closed-loop processing mechanism from code reception, configuration lookup, signal processing to display control decisions and logical judgments. This ensures the accuracy and efficiency of configuration operations and achieves automatic matching of sensor signal processing and functional logic, eliminating the need for manual intervention in underlying parameter settings, reducing the risk of operational errors, and improving the ease of use of the temperature controller.
