This equipment has greatly promoted the flow of information around the world, making instant communication, data acquisition and online activities possible.

[0003] As an important part of power equipment, the box-type transformer measurement, control and protection device effectively ensures the safety of power equipment by continuously monitoring and controlling the operating status and electrical parameters of power equipment. Once an abnormal situation is detected, it can automatically disconnect the circuit according to the set parameters to avoid equipment damage due to overload, short circuit and other reasons. At the same time, adjusting the operating status of power equipment helps to maintain the stable operation of the power grid. Since the box-type transformer measurement, control and protection device can reduce the probability of failures and accidents, its inspection link before leaving the factory is particularly important. This inspection process aims to verify whether the various functions of the box-type transformer measurement, control and protection device are normal through calibration operations. However, the existing calibration method mainly relies on manual operation, that is, the operator needs to calibrate each function one by one and judge its normality, but this manual-dependent method has the risk of operating errors, which affects the accuracy of the calibration results.

The method detects the box-type transformer measurement, control and protection device through a fully automatic process, thereby solving the problem of poor accuracy of calibration results caused by operational errors during manual calibration, thereby improving the accuracy of the calibration results.

[0006] In the first aspect, the present application provides a calibration method for a box-type transformer measurement and control protection device, which is applied to a host computer, and the method includes: receiving a detection request sent by a user, the detection request is used to request to detect the box-type transformer measurement and control protection device; if the host computer and the box-type transformer measurement and control protection device are in normal communication state, a control instruction is sent to the relay, and the relay is controlled to close according to the control instruction, and the box-type transformer measurement and control protection device includes a relay; if the relay is in a closed state, the detection data corresponding to the box-type transformer measurement and control protection device is obtained; it is determined whether the detection data meets preset conditions, and the preset conditions include input data, output data, and multiple calibration conditions in current and voltage data; when the detection data meets the preset conditions, it is confirmed that the calibration of the box-type transformer measurement and control protection device is in a normal state, and a detection pass information is sent to the user, so that the user can perform subsequent operations according to the detection pass information.

[0007] By adopting the above technical solution, the detection request sent by the user is received, and the upper computer and the box-type transformer measurement, control and protection device are in normal communication status, and a control instruction is sent to the relay to control the relay to be in a closed state. The automated operation reduces manual intervention and reduces the problems caused by human operational errors.

This timely feedback allows the user to understand the calibration results in time and perform subsequent operations according to the calibration results. The entire calibration process is completed automatically, reducing the manual operation links, reducing the risk of inaccurate calibration results due to human operational errors, and improving the accuracy of calibration.

[0009] By adopting the above technical solution, the input detection signal of the target input port is automatically obtained, and it is determined whether the input detection signal exists in the preset input detection signal table. Compared with manual detection, automated detection can reduce human errors and ensure that each input port is correctly detected. When the input detection signal exists in the preset input detection signal table, multiple input ports of the box-type transformer measurement, control and protection device are obtained, and the multiple input ports are comprehensively detected to ensure that all input ports are in a normal input state, thereby improving the comprehensiveness and accuracy of the detection.

[0010] Optionally, the detection data satisfies the output data calibration conditions, specifically including: obtaining an output detection signal corresponding to a target output port, the box-type transformer measurement, control and protection device includes multiple output ports, the target output port is any one of the multiple output ports, and the detection data also includes an output detection signal; determining whether there is an output detection signal in a preset output detection signal table; when there is an output detection signal in the preset output detection signal table, confirming that the target output port is in a normal output state; obtaining detection states corresponding to multiple output ports, one output port corresponds to one detection state; if the detection states corresponding to multiple output ports are all normal output states, confirming that the detection data meets the output data calibration conditions.

[0011] By adopting the above technical solution, the output detection signal of the target output port is automatically obtained, and it is determined whether the output detection signal exists in the preset output detection signal table.

[0017] By adopting the above technical solution, a parameter setting data packet is sent to the box-type transformer measurement, control and protection device, and a first confirmation message sent by the box-type transformer measurement, control and protection device is received, so as to ensure that the parameter setting has been correctly executed. After receiving the first confirmation message, the parameter setting data packet is parsed to obtain the second confirmation message, and the first confirmation message is compared with the second confirmation message. When the first confirmation message is consistent with the second confirmation message, it is confirmed that the parameter setting is successful. Through the automated parameter setting and confirmation process, the need for manual intervention is reduced, the operation process is simplified, and work efficiency is improved.

[0038] In order to enable technicians in this field to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

For example, multiple systems refer to two or more systems, and multiple screen terminals refer to two or more screen terminals. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. The terms "include", "comprise", "have" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.

[0041] Electricity is the foundation of the development of communication and Internet technologies, and plays an indispensable role in the continuous operation of electronic devices such as mobile phones and computers. This equipment has greatly promoted the flow of information around the world, making instant communication, data acquisition and online activities possible.

[0042] As an important part of power equipment, the box-type transformer measurement, control and protection device effectively ensures the safety of power equipment by continuously monitoring and controlling the operating status and electrical parameters of power equipment. Once an abnormal situation is detected, it can automatically disconnect the circuit according to the set parameters to avoid equipment damage due to overload, short circuit and other reasons. At the same time, adjusting the operating status of power equipment helps to maintain the stable operation of the power grid. Since the box-type transformer measurement, control and protection device can reduce the probability of failures and accidents, its inspection link before leaving the factory is particularly important. This inspection process aims to verify whether the various functions of the box-type transformer measurement, control and protection device are normal through calibration operations. However, the existing calibration method mainly relies on manual operation, that is, the operator needs to calibrate each function one by one and judge its normality, but this manual-dependent method has the risk of operating errors, which affects the accuracy of the calibration results.

[0043] Therefore, how to solve the problem of poor accuracy of calibration results caused by operational errors during manual calibration is an urgent problem to be solved. The present application provides a calibration method for a box-type transformer measurement and control protection device, which is applied to a host computer. The host computer of the present application can be a platform for calibrating the box-type transformer measurement and control protection device. Figure 1 This is a first flow chart of a calibration method for a box transformer measurement and control protection device provided in an embodiment of the present application, with reference to Figure 1 The method includes the following steps S101-S105.

[0044] S101: receiving a detection request sent by a user, where the detection request is used to request to detect a box-type transformer measurement, control and protection device.

[0045] In the above S101, the host computer receives a detection request sent by a user, and the user refers to a person who calibrates the box-type transformer measurement, control and protection device. The host computer can receive the detection request sent by the user through an interface, an API interface or a dedicated client software. The detection request sent by the user is parsed to confirm that it is a request for safety detection of the box-type transformer measurement, control and protection device. The calibration method provided in this application is applicable to the calibration of all box-type transformer measurement, control and protection devices.

[0046] S102: If the host computer and the box-type transformer measurement, control and protection device are in normal communication state, a control instruction is sent to the relay, and the relay is controlled to close according to the control instruction. The box-type transformer measurement, control and protection device includes a relay.

[0047] In the above S102, after confirming that the host computer is in working state, the host computer is connected to the box transformer measurement and control protection device, and it is ensured that the configuration information and detection parameters of the box transformer measurement and control protection device have been loaded. Then check the connection status of the communication line, that is, whether the host computer and the box transformer measurement and control protection device are in a connected state. The host computer and the box transformer measurement and control protection device can be connected through a network cable or RS485. After the connection, check the connection status to ensure that the host computer and the box transformer measurement and control protection device are in a normal communication state. Since the box transformer measurement and control protection device includes a relay, the relay is found in the box transformer measurement and control protection device, and then a control instruction is sent to the relay according to the communication protocol. The content of the control instruction is to close the relay, that is, the communication line sends an instruction to the relay output module so as to control the relay to close according to the control instruction. The closure of the relay proves that the relay is in working state, and the disconnection of the relay proves that the relay is in non-working state.

[0048] S103: If the relay is in a closed state, the detection data corresponding to the box-type transformer measurement, control and protection device is obtained.

[0049] In the above S103, after confirming that the relay executes the control instruction, it is determined that the relay is in a closed state. After the relay is in a working state, the box-type transformer measurement, control and protection device can be monitored, and then the detection data corresponding to the box-type transformer measurement, control and protection device can be obtained. The detection data includes status data corresponding to the input port, status data corresponding to the output port, and voltage data and current data.

[0050] S104: Determine whether the detection data meets preset conditions, where the preset conditions include multiple calibration conditions in input data, output data, and current and voltage data.

[0051] In the above S104, after obtaining the detection data corresponding to the box-type transformer measurement, control and protection device, it is necessary to determine whether the detection data meets the preset conditions, which include multiple calibration conditions in the input data, output data and current and voltage data. When the detection data is the status data corresponding to the input port, the preset condition is confirmed to be the input data calibration condition. When the detection data is the status data corresponding to the output port, the preset condition is confirmed to be the output data calibration condition. When the detection data is voltage data and current data, the preset condition is confirmed to be the current film data calibration condition.

[0052] S105: When the detection data meets the preset conditions, it is confirmed that the calibration of the box-type transformer measurement, control and protection device is in a normal state, and a detection pass message is sent to the user so that the user can perform subsequent operations according to the detection pass message.

[0053] In the above S105, when the detection data meets the preset conditions, since the preset conditions include multiple calibration conditions in the input data, output data and current and voltage data, it is judged in turn whether the detection data meets the preset conditions corresponding to the preset first number, and the preset first number represents the number corresponding to the three calibration conditions, that is, the preset first number is 3.

[0054] First, when the preset condition is an input data calibration condition, determine whether the detection data meets the input data calibration condition. When the detection data meets the input data calibration condition, it specifically includes: obtaining the input detection signal corresponding to the target input port, the box-type transformer measurement and control protection device includes multiple input ports, the target input port is any one of the multiple input ports, and the detection data includes the input detection signal; determine whether there is an input detection signal in the preset input detection signal table; when the input detection signal exists in the preset input detection signal table, confirm that the target input port is in a normal input state; obtain the detection states corresponding to multiple input ports, one input port corresponds to one detection state; if the detection states corresponding to multiple input ports are all normal input states, confirm that the detection data meets the input data calibration condition. Specifically, the input port corresponding to the box-type transformer measurement and control protection device is monitored. Since the box-type transformer measurement and control protection device includes multiple input ports, each input port needs to be detected in turn. The detection of one of the input ports is used as an example for explanation. Get the target input port, which is any one of the multiple input ports. According to the communication interface of the box-type transformer measurement and control protection device, read the input detection signal on the target input port. The input detection signal can be understood as the current data or voltage data corresponding to the box-type transformer measurement and control protection device in the path state when the relay is in the working state. Since the relay was previously in the disconnected state, the relay is in the non-working state, and the box-type transformer measurement and control protection device does not have current data or voltage data in the open circuit state. Then determine whether there is an input detection signal in the preset input detection signal table. The preset input detection signal table is based on different factory settings of the box-type transformer measurement and control protection device, and then summarizes it into a table containing all possible normal input detection signals. Search for the read input detection signal in the preset input detection signal table. The search process can be accelerated by traversing the table, using database queries, or using data structures such as hash values. Then, according to the search process, determine whether there is a read input detection signal in the preset input detection signal table. When the input detection signal exists in the preset input detection signal table, it is confirmed that the detection state of the target input port is the normal input state. The normal input state means that all input ports are in a normal state and can work normally. In order to detect multiple input ports, multiple input ports can be marked in turn, with one mark corresponding to one input port. Get the input mark corresponding to the target input port, that is, input the first mark, and record the detection status corresponding to the input first mark in the log for subsequent analysis. Repeat the above detection steps and detect other input ports in the box-type transformer measurement, control and protection device in turn. It is necessary to traverse all input ports in the box-type transformer measurement, control and protection device. For each input port, read its corresponding detection status, which is obtained through the above detection method, and then store the detection status of each input port read in the log for subsequent processing.The detection status corresponding to multiple input ports is obtained. When the detection status corresponding to multiple input ports are all in normal input status, it is confirmed that the input port data in the box-type transformer measurement, control and protection device meets the input data calibration condition, that is, the detection data meets the input data calibration condition.

[0055] In addition, when there is no input detection signal in the preset input detection signal table, it is confirmed that the target input port is in an abnormal input state, the input first mark corresponding to the target input port is obtained, and the first warning prompt information is sent to the user. The first warning prompt information indicates that the target input port corresponding to the input first mark is in an abnormal input state, and the target input port needs to be checked in time so as to repair the fault corresponding to the target input port. When the user completes the repair, the target input port is re-judged to determine whether the target input port is in a normal input state.

[0056] Secondly, when the preset condition is the output data calibration condition, determine whether the detection data meets the output data calibration condition. When the detection data meets the output data calibration condition, it specifically includes: obtaining the output detection signal corresponding to the target output port. The box-type transformer measurement, control and protection device includes multiple output ports. The target output port is any one of the multiple output ports. The detection data also includes the output detection signal; determine whether there is an output detection signal in the preset output detection signal table; when there is an output detection signal in the preset output detection signal table, confirm that the target output port is in a normal output state; obtain the detection states corresponding to multiple output ports, one output port corresponds to one detection state; if the detection states corresponding to multiple output ports are all normal output states, confirm that the detection data meets the output data calibration condition. Specifically, the output port corresponding to the box-type transformer measurement, control and protection device is monitored. Since the box-type transformer measurement, control and protection device includes multiple output ports, each output port needs to be detected in turn. The detection of one of the output ports is used as an example for explanation. Obtain the target output port. The target output port is any one of the multiple output ports. Through the output interface of the box-type transformer measurement and control protection device, the output detection signal on the target output port is read. The output detection signal can be understood as the current data and voltage data in the open circuit state, that is, the signal input into the relay by other modules. It is judged whether there is an output detection signal in the preset output detection signal table. The preset output detection signal represents different parameters set by the box-type transformer measurement and control protection device at the factory, and then summarized into a table containing all possible normal output detection signals. The output detection signal read in the preset output detection signal table can be searched by traversing the table, using database query or using data structures such as hash tables to accelerate the search process. According to the search process, it is judged whether there is a read output detection signal in the preset output detection signal table. When the read target output detection signal exists in the preset output detection signal table, it is confirmed that the detection state of the target output port is the normal output state. The normal output state indicates that all relay output ports are working normally. In order to detect multiple output ports, multiple output ports can be marked in turn, and one mark corresponds to one output port. The output mark corresponding to the target output port, that is, the first output mark, is obtained, and the detection state corresponding to the first output mark is recorded in the log for subsequent analysis. Repeat the above detection steps and detect the other output ports in the box-type transformer measurement and control protection device in turn. It is necessary to traverse all the output ports in the box-type transformer measurement and control protection device. For each output port, read its corresponding detection status, which is obtained through the above detection method. The detection status of each output port read is then stored in the log for subsequent processing. Obtain the detection status corresponding to multiple output ports. When the detection status corresponding to multiple output ports is all in the normal output state, it is confirmed that the output port data in the box-type transformer measurement and control protection device meets the output data calibration conditions, that is, the detection data meets the output data calibration conditions.

[0057] In addition, when there is no output detection signal in the preset output detection signal table, it is confirmed that the target output port is in an abnormal output state, the first output mark corresponding to the target output port is obtained, and a second warning prompt information is sent to the user, the second warning prompt information indicates that the target output port corresponding to the first output mark is in an abnormal output state, and the target output port needs to be processed in time. After completing the processing of the target output port, the first output detection signal corresponding to the target output port is re-acquired, and the first output detection signal is judged to determine whether the target output port is in a normal output state.

[0058] Finally, when the preset condition is the current and voltage data calibration condition, it is determined whether the detection data meets the current and voltage data calibration condition. When the detection data meets the current and voltage data calibration condition, it specifically includes: receiving the control instruction sent by the standard voltage and current source, obtaining the first voltage data and the first current data corresponding to the target calibration point, and the standard voltage and current source is connected to the box-type transformer measurement and control protection device; the detection data also includes the first voltage data and the first current data; judging whether the first voltage data is less than or equal to the preset voltage calibration threshold, and judging whether the first current data is less than or equal to the preset current calibration threshold; when the first voltage data is less than or equal to the preset voltage calibration threshold, and the first current data is less than or equal to the preset current calibration threshold, it is confirmed that the target calibration point is in a normal detection state; obtaining the second voltage data and the second current data corresponding to the target verification point, the detection data also includes the second voltage data and the second current data; judging that the second voltage data is less than or equal to the preset voltage verification threshold, and the second current data is less than or equal to the preset current verification threshold, it is confirmed that the target verification point is in a normal detection state; when the target calibration point and the target verification point are both in a normal detection state, it is confirmed that the detection data meets the current and voltage detection data. Specifically, the box-type transformer measurement, control and protection device can be connected to a standard voltage and current source, and then the standard voltage and current source can be controlled through a communication line. The standard voltage and current source can be understood as a signal generator. Ensure that the connection between the standard voltage and current source and the box-type transformer measurement, control and protection device is stable. The box-type transformer measurement, control and protection device receives control instructions from the standard voltage and current source and processes according to the control instructions. In order to better judge whether the current and voltage output by the box-type transformer measurement, control and protection device are within the normal range. A target calibration point can be reserved in the output line of the box-type transformer measurement, control and protection device. The position of the target calibration point can be set based on actual conditions. The target calibration point is used to detect whether the output current and voltage are in a normal state. According to the control instruction, the box-type transformer measurement, control and protection device starts the detection of the target calibration point, and the first voltage data and the first current data corresponding to the target calibration point can be obtained through the built-in voltage or current sensor. Determine whether the first voltage data is less than or equal to the preset voltage calibration threshold, and determine whether the first current data is less than or equal to the preset current standard threshold. The preset voltage calibration threshold and the preset current calibration threshold are set based on the target calibration point. The preset voltage calibration threshold and the preset current calibration threshold are a range, which is a reasonable calibration range based on the parameter setting of the box-type transformer measurement, control and protection device. When the first voltage data is less than or equal to the preset voltage calibration threshold, and the first current data is less than or equal to the preset current standard threshold, it is confirmed that the target calibration point is in a normal detection state. Since a target check point is also reserved on the output line of the box-type transformer measurement, control and protection device, the target check point can be set based on actual conditions. The target check point is used to detect whether the output current and voltage are in a normal state.According to the control instruction, the box-type transformer measurement and control protection device starts the detection of the target check point, and obtains the second voltage data and the second current data corresponding to the target check point through the built-in voltage or circuit sensor again. It is judged whether the second voltage data is less than or equal to the preset voltage check threshold, and whether the second current data is less than or equal to the preset current check threshold. The preset voltage check threshold and the preset current check threshold are set based on the target check point. The preset current check threshold and the preset current check threshold are a range, which is a reasonable verification range based on the parameter setting of the box-type transformer measurement and control protection device. When the second voltage data is less than or equal to the preset voltage check threshold, and the second current data is less than or equal to the preset current check threshold, it is confirmed that the target check point is in a normal detection state. Check the detection status of the target calibration point and the target check point to ensure that they are both in a normal detection state. When the target calibration point and the target check point are both in a normal detection state, it is confirmed that the detection data meets the current and voltage calibration conditions. When the detection data all meet the preset conditions, it can be confirmed that the box-type transformer measurement and control protection device is in a normal state.

[0059] In addition, when the first voltage data is greater than the preset voltage calibration threshold, and the first current data is greater than the preset current calibration threshold, it is confirmed that the target calibration point is in a detection abnormality state. When the second voltage data is greater than the preset voltage verification threshold, and the second current data is greater than the preset current verification threshold, it is confirmed that the target verification point is in a detection abnormality state. If there is a detection abnormality state in the target calibration point and the target verification point, it is confirmed that the calibration of the box-type transformer measurement, control and protection device is in a detection abnormality state, and it is further determined whether the target calibration point is in a detection abnormality state or the target verification point is in a detection abnormality state. Different third warning prompt information is sent according to the judgment result, so that the user can process according to the third warning prompt information.

[0060] Further, when the detection data does not meet the preset conditions, it is confirmed that the calibration of the box-type transformer measurement, control and protection device is in an abnormal state, and an abnormal prompt message is sent to the user, so that the user can process the box-type transformer measurement, control and protection device according to the abnormal prompt message. Specifically, when any one of the detection data does not meet the preset verification conditions, it is confirmed that the calibration of the box-type transformer measurement, control and protection device is in an abnormal state. When the detection data meets any one of the following three situations, it is confirmed that the box-type transformer measurement, control and protection device is in an abnormal state. In the first case, when the detection data does not meet the input data calibration conditions, it is confirmed that the box-type transformer measurement, control and protection device is in an abnormal state. In the second case, when the detection data does not meet the output data calibration conditions, it is confirmed that the box-type transformer measurement, control and protection device is in an abnormal state. In the third case, when the detection data does not meet the current and voltage detection data, it is confirmed that the box-type transformer measurement, control and protection device is in an abnormal state. Different abnormal states are output according to different situations, and different abnormal prompt messages are generated based on different abnormal states, so that the user can process the location where the abnormality or fault occurs in the box-type transformer measurement, control and protection device according to the abnormal prompt message. After receiving the abnormal prompt information, the user should analyze the cause of the abnormal calibration of the box-type transformer measurement and control protection device according to the key information in the abnormal prompt information, and take corresponding measures to deal with the box-type transformer measurement and control protection device according to the analysis results. After the processing is completed, the processing results can be fed back to the relevant personnel for subsequent recording.

[0061] In a possible implementation, when it is confirmed that the detection data meets the preset conditions, the factory parameters of the box-type transformer measurement, control and protection device are set. Specifically, it includes: after confirming that the box-type transformer measurement, control and protection device is in a normal state, sending a parameter setting data packet to the box-type transformer measurement, control and protection device; receiving a first confirmation message sent by the box-type transformer measurement, control and protection device, the first confirmation message is the parameter information that has been successfully set; judging whether the first confirmation message is consistent with the second confirmation message, the second confirmation message is the parameter information obtained by parsing the parameter setting data packet; when the first confirmation message is consistent with the second confirmation message, it is confirmed that the parameters of the box-type transformer measurement, control and protection device are in a successfully set state. Specifically, after the detection is completed, after confirming that the box-type transformer measurement, control and protection device is in a normal state, the factory parameter setting link can be entered. Since the above calibration is performed before the factory setting of the box-type transformer measurement, control and protection device, after the calibration is correct, the factory parameters of the box-type transformer measurement, control and protection device can be set. A parameter setting data packet can be sent to the box-type transformer measurement, control and protection device through a communication line. The parameter setting data packet is composed of multiple preset parameters, and the multiple preset parameters include communication parameters, communication address parameters, communication interface parameters, rated voltage parameters, and rated current parameters. Communication parameters (such as baud rate, data bit, stop bit, etc.), communication address parameters (such as IP address, port number, etc.), communication interface parameters (such as serial port type, USB interface, etc.), rated voltage parameters (such as voltage range when the device is working normally), rated current parameters (such as current range when the device is working normally). After the box-type transformer measurement and control protection device receives the parameter setting data packet, it adjusts the corresponding preset parameters in the parameter setting data packet, and then completes the corresponding settings. The host computer receives the first confirmation information sent by the box-type transformer measurement and control protection device. The first confirmation information indicates that the box-type transformer measurement and control protection device has successfully set the corresponding information of the parameters. When judging whether the first confirmation information is consistent with the second confirmation information, the second confirmation information is the parameter information obtained by parsing the parameter setting data packet. When the first confirmation information is consistent with the second confirmation information, it is confirmed that the factory parameters are in a successful setting state. The setting success status is sent to the user so that the user can promptly confirm that the factory parameters of the box-type transformer measurement and control protection device have been set. In addition to sending multiple preset parameters to the box-type transformer measurement, control and protection device at one time, the preset parameters can also be sent to the box-type transformer measurement, control and protection device in sequence, so that the box-type transformer measurement, control and protection device can set the factory parameters in sequence according to the sent preset parameters.

[0062] Furthermore, when the first confirmation information is inconsistent with the second confirmation information, it is confirmed that the factory parameters are in an unsuccessful setting state, and the unsuccessful setting state needs to be sent to the user so that the user can promptly discover the unsuccessful parameter setting and choose an appropriate method to handle it according to the unsuccessful setting.

[0063] like Figure 2As shown, the calibration process of the box-type transformer measurement and control protection device is automatically triggered. First, it is determined whether the host computer and the box-type transformer measurement and control protection device are in a communication state. When the connection relationship between the host computer and the box-type transformer measurement and control protection device is in a communication state, the control relay is in a closed state. After determining that the relay is in a closed state, the input port of the box-type transformer measurement and control protection device is detected to obtain an input detection signal. Then it is determined whether the input detection signal meets the input data calibration condition. When the input detection signal meets the input data calibration condition, the output port of the box-type transformer measurement and control protection device is detected to obtain an output detection signal. When the input detection signal does not meet the input data calibration condition, it is confirmed that it is in an abnormal state, the abnormal information is recorded, and the calibration process is terminated. Then it is determined whether the output detection signal meets the output data calibration condition. When the output detection signal meets the output data calibration condition, it is confirmed that the first voltage data and the first current data corresponding to the calibration point are obtained. When the output detection signal does not meet the output data calibration condition, it is confirmed that it is in an abnormal state, the abnormal information is recorded, and the calibration process is terminated. Then it is determined whether the first voltage data meets the preset calibration condition, and whether the first current data meets the preset calibration condition. When both the first voltage data and the first current data meet the preset calibration conditions, it is confirmed that the calibration point corresponds to the second voltage data and the second current data. When the first voltage data and the first current data do not meet the preset calibration conditions, it is confirmed that they are in an abnormal state, the abnormal information is recorded, and the calibration process is terminated. It is determined whether the second voltage data meets the preset verification conditions, and whether the second current data meets the preset verification conditions. When both the second voltage data and the second current data meet the preset verification conditions, it is confirmed that the detection of the box-type transformer measurement and control protection device is in a normal state, and the normal state indicates that it is qualified. When the second voltage data and the second current data do not meet the preset verification conditions, it is confirmed that it is in an abnormal state, the abnormal information is recorded, and the calibration process is terminated. After confirming that the box-type transformer measurement and control protection device is qualified in the detection, the factory parameters of the box-type transformer measurement and control protection device are set. After completing the corresponding parameter setting, it is confirmed that the calibration process of the box-type transformer measurement and control protection device is completed. The fully automatic calibration function greatly improves the calibration efficiency and significantly reduces the risk of calibration errors caused by equipment and human operation errors. It not only simplifies the calibration process, but also ensures the accuracy and reliability of the calibration results.
