Description

Technical Field

[0001] The present invention relates to the field of power conversion and control technology, and in particular to a method and system for controlling power conversion across multiple voltage levels. Background Art

[0002] Power conversion control across multiple voltage levels refers to the technology that achieves efficient and stable conversion between power supplies of different voltage levels in application scenarios such as power systems and electronic equipment.

[0003] In modern society, with the widespread application of new energy power generation (such as solar energy and wind energy), the construction of smart grids and the popularization of diversified electronic devices, the demand for power supply voltage of electrical equipment has become more diverse and complex.

[0004] In the traditional power distribution industry, high voltage, medium voltage, and low voltage are all independent components, each with its own independent central control system. When a power source transition occurs in the upper-level distribution system, the lower-level distribution system cannot detect it and initiate a switchover, causing critical equipment to shut down and further reducing the stability of the power supply ecosystem. This situation needs improvement. Summary of the Invention

[0071] The processor is configured to load, execute, and implement the program stored in the memory.

[0072] In summary, this application includes at least one of the following beneficial technical effects:

[0073] 1. By understanding the conversion omen signal of the upper-level power distribution system, potential information on power conversion can be obtained in advance. Then, in response to the omen signal, the overall load capacity is collected, and based on this, the system load state is generated to achieve accurate grasp of the overall power load situation. When the system load state is in a high-load state, the real-time power parameters of the lower-level distribution system are collected in a timely manner, and the load parameters of the lower-level circuit are further obtained. The bus switch state is generated according to the lower-level circuit load parameters, making the control of the bus switch more accurate. Finally, the opening and closing conditions of each bus are adjusted in response to the bus switch state. On the basis of ensuring the stable operation of the lower-level distribution system, the upper-level distribution system is controlled to perform power conversion, thereby improving the stability of the entire power supply ecosystem;

[0074] 2. First, control the cable connection device to drive the circumferential shaking of the connected cable according to the preset parameters and collect the information. If the shaking fails, immediately report the equipment loss alarm to timely discover potential equipment failures. If the cable shaking is normal, control the data acquisition module to continuously collect the overall load capacity and output the shaking collection signal. Use this signal to determine whether the collection is completed. If not, report the equipment loss alarm to ensure the integrity of the data collection. If the collection is completed, stop shaking and maintain the current posture. At the same time, execute the subsequent steps and report the cable abnormality prompt to achieve accurate monitoring and timely processing of the cable status. This not only avoids data anomalies caused by loose or lost equipment, but also can timely discover potential cable problems, providing double protection for the stable operation of the power system;

[0075] 3. When more than one person is simultaneously setting parameters, the system first collects the parameter setting account number, matches the parameter setting identity based on the account number, and obtains the corresponding identity setting parameters to ensure the rationality and pertinence of the parameter setting. The identity and corresponding parameters are then displayed on the preset display terminal, providing a clear reference for parameter selection. After collecting the parameter selection signal, the selected setting parameters are generated based on the signal, and the parameter setting module is controlled to fill the selected parameters into the parameter setting box. This completes the process from identity recognition to parameter selection and setting, thereby avoiding parameter confusion when multiple people are setting parameters and improving parameter setting efficiency.

[0083] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0084] Reference Figure 1 The present invention discloses a method for controlling power conversion across multiple voltage levels, including the following steps:

[0085] S1: Collect the preset conversion omen signal of the upper-level power distribution system.

[0086] The upstream power distribution system refers to a higher-level system in the power distribution network that supplies and controls power to the lower-level power distribution system. The specific upstream power distribution system is pre-defined by those skilled in the art and will not be described in detail here. The pre-switching signal is a status signal indicating that the upstream power distribution system is about to initiate a power switching operation. This pre-switching signal is generated by a pre-set signal transceiver within the upstream power distribution system.

[0087] S2: Responding to the switching precursor signal to collect the overall load capacity.

[0088] Overall load capacity refers to the total power consumed by all downstream power distribution systems and load devices at the current moment, as well as the maximum design power limit that the system can safely carry. Overall load capacity is collected in real time using power sensors. A downstream power distribution system is a lower level in the power distribution network, relative to the upper-level power distribution system. It receives power from the upper-level distribution system and distributes it to specific electrical devices or users.

[0089] When a conversion premonition signal is received, the overall load capacity needs to be collected for subsequent steps.

[0090] S3: Generates system load status based on overall load capacity.

[0091] The system load status refers to a comprehensive quantitative description of the operating status of the power distribution network. It covers the comparison results of the real-time power consumption values ​​of all current lower-level distribution systems and load equipment with the system's safe load limit, and intuitively presents whether the system is in a light load, normal, heavy load or overload state through the load rate.

[0092] By understanding the overall load capacity, we can know the real-time power consumed by all load devices in the current lower-level distribution system and the maximum design power limit that the system can safely carry. Next, the real-time power consumption value is divided by the system's safe load limit and multiplied by 100% to calculate the load factor. Finally, based on the pre-set standard range, such as a load factor of 0 to 60% is considered light load, 60 to 80% is normal, 80 to 90% is heavy load, and over 90% is overload, the calculated load factor is compared with the above standards to clarify the load status of the system. The load factor value is then integrated with the corresponding light load, normal, heavy load, or overload status to form a comprehensive quantitative description of the operating status of the power distribution network, namely the system load status.

[0093] The specific standard range is set by technical personnel in this field based on the actual situation on site and will not be elaborated here.

[0094] S4: When the system load state is a preset high load state, real-time power parameters of a preset lower-level power distribution system are collected.

[0095] In this embodiment, a high load state refers to a load factor exceeding 80%. Real-time power parameters include voltage parameters reflecting power supply quality, current parameters reflecting load size, and power parameters such as active power, reactive power, and apparent power. Real-time power parameters are collected by power monitoring equipment. The specific power monitoring equipment used is common knowledge in the art and is not described here.

[0096] When the system load state is high, it is necessary to first collect the real-time power parameters of the lower-level power distribution system for subsequent steps.

[0097] S5: Obtaining lower-level circuit load parameters based on the real-time power parameters.

[0098] The lower-level circuit load parameters refer to a set of key parameters used to reflect the load characteristics of the lower-level distribution system (such as power factor), power utilization (such as demand coefficient), load balance status of each branch (such as current imbalance) and future load change trends.

[0099] The lower-level circuit load parameters corresponding to the real-time power parameters can be found using a preset lower-level load comparison table. This comparison table records the different lower-level circuit load parameters corresponding to different real-time power parameters. The lower-level load comparison table is generated by those skilled in the art by sequentially testing and recording the different lower-level circuit load parameters corresponding to different real-time power parameters, and is not further described here.

[0100] S6: Generate bus switch status according to the load parameters of the lower circuit.

[0101] The busbar switch status refers to the state of the busbar switch, whether closed, open, or ready for action. The busbar switch status corresponding to the lower-level circuit load parameters can be queried using a preset switch comparison table. This comparison table records the different busbar switch states corresponding to different lower-level circuit load parameters. The switch comparison table is generated by those skilled in the art through sequential testing of different busbar switch states corresponding to different lower-level circuit load parameters, and is not detailed here.

[0102] S7: Responding to the busbar switch status to adjust the opening and closing conditions of each busbar, and after the adjustment is completed, controlling the upper-level power distribution system to perform power conversion.

[0103] The switches on each bus are opened and closed according to the bus switch status. Once the bus switches have been opened and closed, the upper-level distribution system is controlled to switch power. This pre-adjusts the bus switch status based on actual conditions, allowing the lower-level distribution system to sense and switch in advance. After the lower-level distribution system has switched in advance, the upper-level distribution system is controlled to switch power, thus avoiding downtime of critical equipment.

[0104] Reference Figure 2 The method for collecting and detecting the overall load capacity includes the following steps:

[0105] S20: Receive a capacity acquisition signal.

[0106] The capacity acquisition signal is the signal emitted by the data acquisition module after it collects the overall load capacity. After collecting the overall load capacity, the data acquisition module emits a digitally encoded signal, known as the capacity acquisition signal. The data acquisition module is used in power systems to collect and process various power-related data.

[0107] S21: Determine whether the collection of the overall load capacity is completed based on the capacity collection signal.

[0108] By understanding the capacity acquisition signal, it is determined whether the acquisition operation of the overall load capacity is successful, so as to know whether subsequent operations can be performed.

[0109] In this example, the capacity acquisition signal includes signal 1 and signal 2. When the capacity acquisition signal is signal 1, it indicates that the acquisition is complete. When the capacity acquisition signal is signal 2, it indicates that the acquisition is not complete.

[0110] S22: When the collection of the overall load capacity is completed, the preset data collection module is controlled to adjust the data units in the overall load capacity to corresponding preset data units, and store them in a preset capacity storage terminal.

[0111] The capacity storage terminal refers to a terminal for storing various capacity data collected by the data collection module. The specific capacity storage terminal is set in advance by those skilled in the art and will not be described in detail here.

[0112] When the overall load capacity is collected, the capacity collection signal is signal 1. The data collection module is then controlled to adjust the data units in the overall load capacity to the corresponding preset data units for subsequent viewing and use. Finally, the overall load capacity is stored in a preset capacity storage terminal for subsequent steps.

[0113] The specific data units that need to be adjusted are set in advance by those skilled in the art and will not be described in detail here.

[0114] S220: After the capacity storage is completed, the preset display terminal is controlled to display the overall load capacity data.

[0115] The display terminal is used to display various data in the power system. After the capacity storage is completed, the display terminal needs to be controlled to display the overall load capacity data for viewing.

[0116] S23: When the collection of the overall load capacity is not completed, controlling the preset data collection module to continue collecting the overall load capacity and collecting the number of data collection times.

[0117] The number of data collection attempts refers to the number of times the data collection module attempts to collect the overall load capacity if it fails to complete the collection. The overall load capacity is calculated using a virtual counter preset within the data collection module. Each time the data collection module collects data, the virtual counter increments by one.

[0118] When the collection of the overall load capacity is not completed, it indicates that the capacity collection signal is signal 2, and the data collection module needs to be controlled to continuously collect the overall load capacity and collect the data collection times.

[0119] S230: When the number of data collection times exceeds the preset warning collection times, a device loss alarm is reported.

[0120] The number of early warning collection times refers to the maximum number of times the data collection module can repeatedly attempt to collect the overall load capacity. The number of early warning collection times is set in advance by those skilled in the art and will not be described in detail here.

[0121] When the number of data collection times exceeds the warning collection times, it means that the number of continuous collection times is too many and the overall load capacity cannot be collected, and a device loss alarm needs to be reported.

[0122] When the data collection times have not exceeded the warning collection times and the overall load capacity has been collected, steps S22 to S220 may be executed.

[0123] Reference Figure 3 , the device loss detection method includes the following steps:

[0124] S231: Collect cable image information.

[0125] Cable image information refers to the images of cables used for data transmission on devices related to the overall load capacity collected by the data acquisition module. Cable image information is obtained by taking pictures with a camera.

[0126] S232: Determine whether the preset connection cable is inserted into the interface based on the cable image information, the preset cable characteristics, and the interface characteristics.

[0127] Cable characteristics refer to the external contours of the connecting cable. Interface characteristics refer to the external contours of the interface used to connect to the connecting cable on the device related to the overall load capacity collected by the data acquisition module. The connecting cable refers to the cable used for data transmission. Both cable characteristics and interface characteristics are pre-determined by those skilled in the art and are not detailed here.

[0128] By determining whether the connection cable is inserted into the interface, you can know whether the device is lost due to a loose cable.

[0129] By scanning and identifying the cable features and interface features in the cable image information, it is possible to determine whether the connected cable has been removed from the interface. Image recognition technology is common knowledge in this field and will not be described in detail here.

[0130] S233: When the connection cable is not inserted into the interface, control the preset cable connection device to raise the connection cable at a preset raising height value, and collect raising image information.

[0131] The cable connection device is a device used to connect a connection cable to an interface. The elevation height value refers to the height at which the cable connection device raises a dislodged connection cable back to the same level as the interface. The elevation height value is pre-set by those skilled in the art and is not detailed here. The elevation image information refers to the image of the connection cable after it has been raised. The elevation image information is captured by a camera.

[0132] When the connecting cable is not inserted into the interface, it means that the cable has come out of the interface and fallen to the ground. It is necessary to control the cable connection device to raise the connecting cable to the raising height value and collect the raising image information for subsequent steps.

[0133] S2330: Generate an interface distance value based on the elevation image information, cable characteristics, interface characteristics, and a preset reference object.

[0134] A reference object refers to an object used to assist in comparing the actual size and position of each feature in the image. The size and position of the reference object are set in advance by those skilled in the art and will not be described in detail here. The interface distance value refers to the distance between the connecting cable and the interface. The position and size of the reference object in the image, as well as the distance between the cable features and the interface features in the image, can be identified from the elevated image information. Combined with the actual size and position of the reference object, the proportion of the elevated image information can be known, and the actual interface distance value can be compared with the distance between the cable features and the interface features in the image.

[0135] S2331: Controlling the cable connection device to move toward the interface feature direction in response to the interface distance value, and inserting the cable connection device with a preset insertion force value after the movement is completed.

[0136] The insertion force value refers to the force used to secure the connecting cable into the interface. The insertion force value is pre-determined by those skilled in the art and will not be detailed here. The control cable connection device uses the interface distance value to drive the connecting cable toward the interface's characteristic direction. After the movement is completed, the insertion force value is used to insert the cable.

[0137] Reference Figure 4 , the device loss detection method further includes the following steps:

[0138] S234: When the connecting cable is inserted into the interface, the preset cable connecting device is controlled to insert the connecting cable into the characteristic direction of the interface with a preset insertion force value.

[0139] When the connecting cable is inserted into the interface, it means that the cable has not completely come out of the interface, and further looseness detection is required. Then, the cable connecting device needs to be controlled to insert the connecting cable into the characteristic direction of the interface with the insertion force value for subsequent steps.

[0140] S235: After the insertion is completed, the data acquisition module is controlled to collect the overall load capacity again and output a re-collection signal.

[0141] The re-collection signal is the signal sent by the data acquisition module when the data acquisition module re-collects the overall load capacity after the connecting cable is inserted into the interface characteristic direction with the insertion force value. The re-collection signal is similar to the capacity collection signal in S20 above and will not be described in detail here.

[0142] After the insertion is completed, the data acquisition module needs to be controlled to collect the overall load capacity again and output a re-collection signal for subsequent steps.

[0143] S236: Determine whether the collection of the entire load capacity is completed based on the re-collection signal.

[0144] This step is similar to the above-mentioned S21 and will not be described in detail here.

[0145] S237: When the collection of the overall load capacity is completed, execute S22 to S220.

[0146] When the collection of the overall load capacity is completed, it indicates that the recollected signal is signal 1, which further indicates that the reason for the device loss is a loose cable, and S22 to S220 can be executed.

[0147] S238: When the collection of the overall load capacity is not completed, the cable connection device is controlled to detect the cable using a preset surrounding detection method.

[0148] The surround detection method is a method for further detecting the connection cable. The specific surround detection method is described in detail in the subsequent S2380 to S23822 and will not be described in detail here.

[0149] When the collection of the overall load capacity is not completed, it indicates that the recollected signal is signal 2. To further detect the connected cables, the cable connection device needs to be controlled to detect the cables using a surround detection method.

[0150] Reference Figure 5 , the surround detection method comprises the following steps:

[0151] S2380: Control the cable connection device to drive the connecting cable to swing circumferentially at a preset swing intensity value and swing speed, and collect the cable swing conditions.

[0152] The "sway intensity value" refers to the force applied when the connecting cable is shaken circumferentially. The "sway speed" refers to the speed at which the connecting cable is shaken circumferentially. Both the "sway intensity value" and the "sway speed" are pre-determined by those skilled in the art and are not detailed here. The "cable shake condition" refers to the motion state, amplitude, frequency, and other related information exhibited by the connecting cable during circumferential shaking. The cable shake condition is measured by an acceleration sensor pre-installed on the cable connection device.

[0153] When the control cable connection device drives the connection cable to oscillate circumferentially at a swaying intensity and speed, the cable swaying situation needs to be collected synchronously for subsequent steps.

[0154] S2381: When the cable shaking condition is consistent with the preset non-shaking condition, a device loss alarm is reported.

[0155] The "no shaking condition" refers to a state in which the connecting cable does not shake when the connecting cable is driven by the cable connecting device to shake circumferentially. The "no shaking condition" is pre-set by those skilled in the art and will not be described in detail here.

[0156] If the cable shakes and cannot shake, it means that the connection cable and the interface are properly fixed. This means that the cause of device loss is not a connection problem between the connection cable and the interface. You need to report a device loss alarm.

[0157] S2382: When the cable shaking condition is inconsistent with the preset non-shaking condition, the data acquisition module is controlled to continuously collect the overall load capacity and output a shaking collection signal.

[0158] The sway acquisition signal refers to the signal sent by the data acquisition module when collecting the overall load capacity during the circumferential sway of the connecting cable. The sway acquisition signal is similar to the capacity acquisition signal in S20 above and will not be described in detail here.

[0159] When the cable shaking condition is inconsistent with the condition of being unable to shake, it means that the connecting cable is shaking when it is driven by the cable connecting device to shake circumferentially. It is necessary to control the data acquisition module to continuously collect the overall load capacity during the period of circumferential shaking of the connecting cable and output a shaking collection signal for subsequent steps.

[0160] S23820: Determine whether the collection of the overall load capacity is completed based on the shaking collection signal.

[0161] This step is similar to the above-mentioned S21 and will not be described in detail here.

[0162] S23821: When the collection of the overall load capacity is not completed, the device loss alarm is reported.

[0163] When the collection of the overall load capacity is not completed, it indicates that the shaking collection signal is signal 2, which means that the cause of the device loss is not a connection problem between the connecting cable and the interface, and a device loss alarm needs to be reported.

[0164] S23822: When the collection of the overall load capacity is completed, the cable connection device is controlled to stop shaking and maintain the current posture, and S22 to S220 are executed at the same time, and a cable abnormality prompt is reported.

[0165] When the collection of the overall load capacity is completed, it means that the shaking collection signal is signal 1, which means that the reason for the loss of the equipment is the connection problem between the connecting cable and the interface. The cable connection device needs to be controlled to stop shaking and maintain the current posture so that the connecting cable and the interface can be temporarily used. At the same time, S22 to S220 need to be executed, and the cable abnormality prompt must be reported to prompt the staff to carry out maintenance.

[0166] The system parameter setting method includes the following steps:

[0167] S80: Collecting the parameter setting signal of the preset parameter setting box.

[0168] The parameter setting box is a text box in the power system used by personnel to set various threshold parameters. The parameter setting box is pre-configured by those skilled in the art and will not be described in detail here. The parameter setting signal is the signal generated when a person enters parameters in the parameter setting box. The parameter setting signal is collected by embedding an event listener in the front-end interface of the parameter setting box.

[0169] S81: Responding to the parameter setting signal to match the parameters and set the number of people.

[0170] The number of people concurrently setting parameters refers to the number of people currently setting parameters in the parameter setting box. The number of people concurrently setting parameters corresponding to the parameter setting signal can be matched using a preset number of people database. This database stores different numbers of people concurrently setting parameters corresponding to different parameter setting signals. The number of people database is created by those skilled in the art by sequentially recording different numbers of people concurrently setting parameters corresponding to different parameter setting signals, and is not further described here.

[0171] For example, when the parameter setting signal is A, the corresponding parameter in the number of people database is set to 1 at the same time. When the parameter setting signal is B, the corresponding parameter in the number of people database is set to 2 at the same time.

[0172] S82: When the number of people setting the parameters at the same time is not greater than 1, the parameter setting content is collected and the parameter setting box is filled in based on the parameter setting content.

[0173] The parameter setting content refers to the content of the parameter setting box when the staff sets the parameters. The parameter setting content is collected through front-end interactive capture. Front-end interactive capture is common knowledge in the field and will not be described in detail here.

[0174] When the number of people setting parameters at the same time is not more than 1, it means that only one staff member is setting parameters in the parameter setting box. The parameter setting content of the staff member can be directly collected and filled in the parameter setting box based on the parameter setting content.

[0175] S83: When the number of people setting the parameters at the same time is greater than 1, the preset parameter setting module is controlled to determine the parameters using a preset parameter determination method, and fills in the parameter setting box based on the determined parameter content.

[0176] The parameter setting module refers to a functional component for receiving, processing, and determining various parameter setting-related operations. The parameter setting module is pre-configured by those skilled in the art and is not described in detail here. The parameter determination method refers to the method used to determine the specific input content required for the parameter setting box when multiple people are simultaneously entering parameters into the parameter setting box. The specific parameter determination method is described in detail in subsequent steps S830 to S835 and is not described in detail here.

[0177] When the number of people setting parameters at the same time is greater than 1, it means that multiple people are inputting parameters into the parameter setting box at the same time. The parameter setting module needs to be controlled to determine the parameters using the parameter determination method and fill in the parameter setting box based on the determined parameter content.

[0178] Reference Figure 6 , the parameter determination method comprises the following steps:

[0179] S830: When the number of people setting parameters at the same time is greater than 1, collect parameter setting accounts.

[0180] The parameter setting account refers to the account of the staff who enters parameters in the parameter setting box. The parameter setting account is collected from the user login interface.

[0181] When the number of people setting parameters at the same time is greater than 1, the parameter setting account number needs to be collected for subsequent steps.

[0182] S831: Match the parameter setting identity based on the parameter setting account, and collect the identity setting parameters corresponding to the parameter setting identity.

[0183] The parameter setting identity refers to the specific identity of the staff member who enters parameters in the parameter setting box. The parameter setting identity corresponding to the parameter setting account can be matched through a preset identity database, which stores different parameter setting identities corresponding to different parameter setting accounts. The identity database is formed by technicians in this field recording different parameter setting identities corresponding to different parameter setting accounts in sequence, and will not be described in detail here. The identity setting parameters refer to the parameters entered in the parameter setting box by the staff member corresponding to the parameter setting identity. The content entered by the parameter setting identity will be bound to the identity setting parameters through the front-end data, so the identity setting parameters corresponding to the parameter setting identity can be obtained by retrieving the front-end data.

[0184] After matching the parameter setting identity, the identity setting parameters corresponding to the parameter setting identity need to be collected for subsequent steps.

[0185] S832: Control the parameter setting module to display the parameter setting identity and the identity setting parameters corresponding to the parameter setting identity on a preset display terminal.

[0186] The control parameter setting module displays the parameter setting identity and the identity setting parameters corresponding to the parameter setting identity on the display terminal for viewing by all staff members who have participated in the parameter input so that the staff members can select the input parameters by themselves.

[0187] S833: Acquisition parameter selection signal.

[0188] A parameter selection signal is an electronic instruction used by a worker to express their final selection intention through a preset interactive control (such as a radio button, drop-down menu, or confirmation button) after viewing the various parameter setting identities and their corresponding identity setting parameters displayed on the display terminal. The specific interactive controls used are pre-defined by those skilled in the art and are not described in detail here. The parameter selection signal is collected by an event listener bound to the interactive control.

[0189] S834: Generate selected setting parameters based on the parameter selection signal.

[0190] Selecting a setting parameter refers to the operator's final selection of the parameters to be entered into the parameter setting box after viewing the various parameter setting identities and their corresponding identity setting parameters displayed on the display terminal. By understanding the parameter selection signal, the operator's specific identity setting parameters can be known, and the selected setting parameters can be obtained.

[0191] For example, suppose two workers, A and B, are simultaneously setting parameters in the same parameter setting box. A's setting is 1, and B's setting is 2. The parameter setting module will display the parameters set by A and B on the display terminal. When the final parameter selection is completed, the selected setting parameters can be determined by understanding the parameter selection signal. The parameter selection signal includes signal a, corresponding to the parameter selected by A, and signal b, corresponding to the parameter selected by B. Therefore, when the parameter selection signal is a, the selected setting parameter is 1; similarly, when the parameter selection signal is b, the selected setting parameter is 2.

[0192] S835: The control parameter setting module fills the parameter setting box with the selected setting parameters.

[0193] The control parameter setting module fills the parameter setting box with the selected setting parameters to complete the parameter setting.

[0194] The following steps are also included:

[0195] S90: Collect parameter detection signals.

[0196] Parameter detection signals are signals used to detect various parameters in the power system. These signals include real-time observation signals and virtual observation signals. Parameter detection signals are obtained through pre-set signal transceiver terminals in the power system. When personnel need to detect various parameters in the power system, they send parameter detection signals to the signal transceiver terminals. Signal transceiver terminals are terminals used to receive and transmit various signals. These terminals are pre-configured by those skilled in the art and are not described here.

[0197] Real-time observation signals refer to signals used when various parameters in the power system are observed in real time using a camera. Virtual observation signals refer to signals used when only online data observation of various parameters in the power system is required. Both real-time observation signals and virtual observation signals are pre-defined by those skilled in the art and are not described here.

[0198] S91: When the parameter detection signal is consistent with the preset real-time observation signal, the on-site image information is collected.

[0199] On-site image information refers to real-time images captured by display terminals that record various parameters in the power system. On-site image information is captured by cameras.

[0200] When the parameter detection signal is consistent with the real-time observation signal, it means that the staff needs to observe various parameters in the power system by viewing the on-site images and needs to collect on-site image information for subsequent steps.

[0201] When the parameter detection signal is consistent with the virtual observation signal, it means that the staff does not need to view the on-site image, and can directly transmit various parameters for the staff to view.

[0202] S92: Scan and identify the preset parameter setting position from the on-site image information to determine whether there is a preset screen reflection feature at the parameter setting position.

[0203] The parameter setting location refers to the location on the display terminal used to set parameters. This location displays the parameters that the operator needs to observe. The screen reflection characteristic refers to the characteristics of reflections on the display terminal screen. Both the parameter setting location and the screen reflection characteristic are pre-determined by those skilled in the art and are not described in detail here.

[0204] The parameter setting position is scanned and identified from the on-site image information to determine whether there is a screen reflective feature at the parameter setting position. Identifying reflective features from an image is common knowledge in the art and will not be described in detail here.

[0205] S93: When there is no screen reflection feature at the parameter setting position, the real-time observation is completed.

[0206] When there is no screen reflective feature at the parameter setting location, it means that the parameters on the screen can be directly observed and real-time observation can be completed directly.

[0207] S94: When a screen reflection feature exists at the parameter setting position, a preset reflection processing method is used to perform reflection processing on the preset display terminal.

[0208] The reflection processing method refers to a method for processing the reflection situation existing in the display terminal. The specific reflection processing method is described in detail in the subsequent S940 to S9430 and will not be described in detail here.

[0209] When there are screen reflective features at the parameter setting location, it means that the parameters on the screen cannot be observed. The display terminal needs to be reflectively processed using a reflective processing method to facilitate observation by staff.

[0210] Reference Figure 7 , the reflective processing method comprises the following steps:

[0211] S940: Selecting an available display area based on on-site image information, screen reflection characteristics, and preset screen display characteristics.

[0212] Screen display features refer to the appearance and contour features of the display terminal's screen. Screen display features are pre-determined by those skilled in the art and are not described in detail here. The usable display area refers to the area on the screen that is free of reflections and therefore visible. Areas with screen reflections are removed from the live image information and then combined with the screen display features to determine the usable display area. Image recognition technology is common knowledge in the art and is not described in detail here.

[0213] S941: Determine whether the available display area is larger than the preset required display area.

[0214] The required display area refers to the area size required to display the parameter setting box. The required display area is set in advance by those skilled in the art and will not be described in detail here.

[0215] By judging whether the available display area is larger than the required display area, the parameter setting box can be placed in the available display area for staff to observe.

[0216] S942: When the available display area is not larger than the required display area, control a preset anti-reflective device to be placed on the display terminal and rotate it at a preset rotation speed in real time.

[0217] An anti-reflective device refers to a polarizing plate used to reduce the degree of reflection on a display terminal. The rotation speed refers to the speed at which the anti-reflective device rotates after being placed on the display terminal. The rotation speed is set in advance by those skilled in the art and will not be detailed here.

[0218] When the available display area is not larger than the required display area, it means that the parameter setting box cannot be placed in the available display area. The anti-glare device needs to be controlled to be placed on the display terminal and rotated at a rotation speed in real time for subsequent steps.

[0219] S9420: When the anti-reflective device rotates, the preset shooting device is controlled to collect on-site image information in real time until the screen reflection feature no longer exists at the parameter setting position, thereby completing real-time observation.

[0220] The shooting device refers to a camera used to collect on-site image information.

[0221] When the anti-reflective device rotates, the camera is controlled to collect on-site image information in real time until there is no screen reflection feature at the parameter setting position, so that the staff can clearly observe the parameters and complete real-time observation.

[0222] S943: When the available display area is larger than the required display area, generate parameter box movement parameters based on the available display area and the parameter setting position.

[0223] The parameter box movement parameters refer to the direction and distance the parameter setting box moves on the screen. By understanding the relative position between the parameter setting location and the available display area, we can determine the movement direction. Then, using pixel counting, we can calculate the distance the parameter setting box moves from the available display area to the parameter setting location, thereby obtaining the parameter box movement parameters.

[0224] When the available display area is larger than the required display area, it means that the parameter setting box can be placed in the available display area. You need to generate the parameter box first to move the parameters for subsequent steps.

[0225] S9430: Move the parameters based on the parameter box to control the position movement of the parameter setting box.

[0226] The control parameter setting box moves the position by moving the parameters in the parameter box, and then collects the on-site image information again for the staff to observe the parameters.
