In a substation, the protection control panel is a fundamental secondary component, a type of relay protection device that correctly activates the opening and closing circuits to disconnect large loads and faults. The protection control panel is a crucial component for protecting the safety of power grid equipment. Therefore, improving the control accuracy of intelligent remote control panels in substations is a technical problem that needs to be studied in this field. Summary of the Invention

[0004] This invention provides a method and device for controlling a substation intelligent remote control pressure plate, which can solve at least one of the above-mentioned technical problems.

[0005] According to one aspect of the present invention, a method for controlling a substation intelligent remote control pressure plate is provided, comprising:

[0006] In response to the control command for the operation of the substation operation switch, the following position verification operations are performed before and after the operation of the operation switch corresponding to the control command is executed:

[0007] The detection switch position of the pressure plate rotation limit switch and the detection resistance of the pressure plate rotation resistance in the substation's engagement / disengagement pressure plate are obtained;

[0008] The mechanical position of the pressure plate is determined based on the difference between the position of the detection switch and the position of the reference switch corresponding to the pressure plate engagement / disengagement operation.

[0009] The electrical position of the pressure plate is determined based on the difference between the detection resistor and the reference resistor corresponding to the pressure plate engagement / disengagement operation.

[0010] When the mechanical position of the pressure plate is consistent with the electrical position of the pressure plate, the current pressure plate position of the substation activation / deactivation pressure plate is determined based on the mechanical position of the pressure plate, and it is verified whether the current pressure plate position matches the position requirement before or after the execution of the activation / deactivation control command.

[0011] According to another aspect of the present invention, a substation intelligent remote control pressure plate control device is provided. The device is configured to, in response to a control command for engaging or disengaging a substation pressure plate, perform position verification operations using the following modules before and after controlling the substation pressure plate to execute the pressure plate engaging or disengaging operation corresponding to the control command:

[0012] The information acquisition module is used to acquire the detection switch position of the pressure plate rotation limit switch and the detection resistance of the pressure plate rotation resistance in the substation activation / deactivation pressure plate;

[0013] The mechanical position determination module is used to determine the mechanical position of the pressure plate based on the difference between the position of the detection switch and the reference switch position corresponding to the pressure plate engagement / disengagement operation.

[0014] An electrical position determination module is used to determine the electrical position of the pressure plate based on the difference between the detection resistor and the reference resistor corresponding to the pressure plate engagement / disengagement operation.

[0015] The pressure plate position verification module is used to determine the current pressure plate position of the substation activation / deactivation pressure plate based on the mechanical position of the pressure plate when the mechanical position of the pressure plate is consistent with the electrical position of the pressure plate, and to verify whether the current pressure plate position matches the position requirements before or after the execution of the activation / deactivation control command.

[0016] According to one aspect of the present invention, an electronic device is provided, comprising: at least one processor, and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the processor, and the processor is configured to retrieve the instructions from the memory and execute the instructions to enable the processor to execute the substation intelligent remote control pressure plate control method according to any embodiment of the present invention.

[0017] According to one aspect of the present invention, a non-transitory computer-readable storage medium storing computer instructions is provided, the computer instructions being provided to a computer to instruct the computer to execute the substation intelligent remote control pressure plate control method according to any one of the embodiments of the present invention.

[0018] By employing the technical solution of this invention, in response to the control command for the engagement / disengagement of a substation engagement / disengagement plate, the following position verification operations are performed before and after the engagement / disengagement operation corresponding to the control command is executed: The detection switch position of the plate rotation limit switch and the detection resistance of the plate rotation resistance are obtained; the mechanical position of the plate is determined based on the difference between the detection switch position and the reference switch position corresponding to the engagement / disengagement operation; the electrical position of the plate is determined based on the difference between the detection resistance and the reference resistance corresponding to the engagement / disengagement operation; if the mechanical and electrical positions of the plate are consistent, the current plate position of the substation engagement / disengagement plate is determined based on the mechanical position to verify whether the current plate position matches the position requirements before or after the execution of the engagement / disengagement control command. Therefore, only when the mechanical position of the pressure plate corresponding to the detection switch position of the pressure plate rotation limit switch is consistent with the electrical position of the pressure plate corresponding to the detection resistance of the pressure plate rotation resistance, is the current pressure plate position of the substation's engagement / disengagement pressure plate determined using the mechanical position of the pressure plate. This ensures the reliability of verifying whether the current pressure plate position of the substation's engagement / disengagement pressure plate matches the position requirements before or after the execution of the engagement / disengagement control command. Consequently, the control reliability of the substation's engagement / disengagement pressure plate can be ensured subsequently.

[0029] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0030] Figure 1 This is a flowchart of a substation intelligent remote control pressure plate control method according to an embodiment of the present invention.

[0031] like Figure 1 As shown, the intelligent remote control method for the substation includes:

[0032] S110, in response to the control command for the operation of the substation control plate, performs the following position verification operations before and after controlling the substation control plate to perform the control plate operation corresponding to the control command:

[0033] S111, obtain the detection switch position of the pressure plate rotation limit switch and the detection resistance of the pressure plate rotation resistance in the substation's pressure plate;

[0034] S112, Determine the mechanical position of the pressure plate based on the difference between the position of the detection switch and the reference switch position corresponding to the pressure plate engagement / disengagement operation;

[0035] S113, Determine the electrical position of the pressure plate based on the difference between the detection resistor and the reference resistor corresponding to the pressure plate engagement / disengagement operation;

[0036] S114, when the mechanical position and electrical position of the pressure plate are consistent, determine the current pressure plate position of the substation's power-on / power-off pressure plate based on the mechanical position of the pressure plate, and verify whether the current pressure plate position matches the position requirements before or after the execution of the power-on / power-off control command.

[0037] Understandably, before controlling the substation's engagement / disengagement pressure plate to execute the pressure plate engagement / disengagement operation corresponding to the engagement / disengagement control command, steps S111 to S114 are performed. Step S114 includes verifying whether the current pressure plate position matches the position requirement before the execution of the engagement / disengagement control command. If it is determined that the current pressure plate position matches the position requirement before the execution of the engagement / disengagement control command, the substation's engagement / disengagement pressure plate is controlled to execute the pressure plate engagement / disengagement operation corresponding to the engagement / disengagement control command.

[0038] Understandably, after the substation's control plate performs the control command to activate or deactivate the corresponding plate, steps S111 to S114 are executed. Step S114 includes verifying whether the current plate position matches the post-execution position requirement of the control command. If it is determined that the current plate position matches the post-execution position requirement of the control command, the operation of the control plate corresponding to the control command is considered a successful operation.

[0039] Understandably, the method of this invention can be applied to the control system of substation switching on / off switch plates, which may include multiple different switch plates for controlling different power grid paths or power grid equipment.

[0040] Understandably, the engagement / disengagement control command may include the position number of the target pressure plate, as well as the pressure plate engagement command or pressure plate disengagement command.

[0041] For example, the working process of a substation intelligent remote control pressure plate may include the following:

[0042] First, the substation maintenance personnel control the activation and deactivation of the pressure plate on the substation's back-end computer. The substation's back-end computer sends the activation and deactivation control command to the integrated control module of the target cabinet through the communication module.

[0043] Then, the integrated control module checks whether the current pressure plate position meets the engagement / disengagement conditions, i.e., the pre-execution position requirements, using steps S111 to S114. If it does, the integrated control module selects the corresponding target pressure plate according to the pressure plate position number in the engagement / disengagement control command, and outputs the control command (pressure plate engagement command or pressure plate disengagement command) in the engagement / disengagement control command to drive the servo motor of the target pressure plate. Thus, it can control the target pressure plate to move according to the pressure plate engagement command or pressure plate disengagement command in the engagement / disengagement control command.

[0044] Next, after the controlled target pressure plate completes the above-mentioned engagement / disengagement operation, the integrated control module uses steps S111 to S114 of this invention to determine whether the current pressure plate position meets the post-execution position requirements, thereby determining whether the pressure plate engagement / disengagement operation is in a normal operating state. This ensures the reliability of the substation's pressure plate engagement / disengagement control.

[0045] For example, an electromagnetic encoder can be installed in the pressure plate rotation limit switch to detect the switch position. When the pressure plate rotation limit switch rotates, the switch position detected by the electromagnetic encoder will change accordingly. The switch position detected by the electromagnetic encoder can be represented by a numerical value.

[0046] For example, such as Figure 2 and Figure 3 As shown, the substation activation / deactivation pressure plate may include a pressure plate base 20, and the pressure plate 7 includes an upper conductive sheet 7-1, a lower conductive sheet 7-2, an insulating medium 7-3 located between the upper and lower conductive sheets, an upper stationary contact 4, a lower stationary contact 6, an upper moving contact 9, and a lower moving contact 10.

[0047] The substation activation / deactivation pressure plate also features an insulated knob 5 and a manual operation cross-threaded hole 8, allowing for manual operation to rotate the pressure plate.

[0048] The substation power control plate may also include a power-operated power-on button 11 and a power-operated power-off button 12. During the power control plate operation, pressing button 11 or button 12 will execute the corresponding power control plate operation according to the power control plate operation command corresponding to that button.

[0049] The substation activation / deactivation switch can also include a power indicator light 1, a normal status indicator light 2, and an abnormal status indicator light 3 to indicate the working status of the switch.

[0050] The substation activation / deactivation pressure plate may also include an LCD digital display 13, which is used to display the voltage values ​​at both ends of the pressure plate.

[0051] The substation activation / deactivation pressure plate may also include a cable protection sleeve 14 and a spring 15.

[0052] The substation engagement / disengagement pressure plate also includes a servo motor 17 for performing the engagement / disengagement operation of the pressure plate. The servo motor is equipped with an electromagnetic encoder that records the pressure plate position. The servo motor 17 is mounted with a motor shaft 18, an external gear 16, and an internal gear 19. The external gear 16 is connected to the motor shaft 18. The servo motor 17 drives the internal gear 19 to rotate, and the external gear 16 meshes with the internal gear 19, causing the pressure plate connecting rod to rotate.

[0053] For example, such as Figure 4 and Figure 5 As shown, the rotation of the pressure plate causes a change in the resistance of the resistance wire connected in series with the resistance measurement circuit, including the upper resistance measurement end 31, the lower resistance measurement end 32, and the resistance wire 33 that rotates with the pressure plate. Among these, Figure 4 The position of the resistance wire 33 relative to the upper end 31 of the resistance measurement is shown when the pressure plate is engaged. Figure 5The position of the resistance wire 33 relative to the upper end 31 of the resistance measurement is shown when the pressure plate is in the withdrawn state.

[0054] Understandably, the resistance wire 33 is the pressure plate rotation resistor in this embodiment of the invention.

[0055] For example, the resistance value of the resistance wire in the resistance measuring circuit can be detected when the pressure plate rotates. Here, the resistance wire is the resistance of the pressure plate during rotation.

[0056] Understandably, if the engagement / disengagement control command is an engagement control command, the corresponding plate engagement / disengagement operation is a plate engagement operation. If the engagement / disengagement control command is a disengagement control command, the corresponding plate engagement / disengagement operation is a plate disengagement operation.

[0057] For example, the difference between the detection switch position and the reference switch position corresponding to the pressure plate engagement / disengagement operation is calculated, and the difference is normalized to obtain the mechanical position of the pressure plate.

[0058] For example, the electrical position of the pressure plate can be obtained by calculating the difference between the detection resistor and the reference resistor corresponding to the pressure plate engagement / disengagement operation, and normalizing the difference.

[0059] For example, if the numerical difference between the mechanical position and the electrical position of the pressure plate is less than a preset threshold, then the mechanical position and the electrical position of the pressure plate are determined to be consistent. If the numerical difference between the mechanical position and the electrical position of the pressure plate is greater than the preset threshold, then the mechanical position and the electrical position of the pressure plate are determined to be inconsistent, and corresponding alarm information needs to be generated.

[0060] Understandably, assuming the mechanical and electrical positions of the pressure plate are consistent, the mechanical position is used as the current pressure plate position for the substation's engagement / disengagement control. The current pressure plate position is then verified to match the pre- or post-execution position requirements of the engagement / disengagement control command. For example, if the engagement / disengagement control command is executed before execution, the current pressure plate position is verified to match the pre-execution position requirements. If the engagement / disengagement control command is executed after execution, the current pressure plate position is verified to match the post-execution position requirements.

[0061] Alternatively, by utilizing the mechanical position of the pressure plate, the current pressure plate position of the substation's engagement / disengagement pressure plate can be verified in multiple different ways before outputting the current pressure plate position of the successfully verified substation engagement / disengagement pressure plate.

[0062] According to the above implementation method, in response to the control command for the operation of the substation operation plate, before and after controlling the substation operation plate to perform the operation corresponding to the control command, the following position verification operations are performed respectively: obtaining the detection switch position of the plate rotation limit switch and the detection resistance of the plate rotation resistance in the substation operation plate; determining the mechanical position of the plate based on the difference between the detection switch position and the reference switch position corresponding to the operation of the plate operation; determining the electrical position of the plate based on the difference between the detection resistance and the reference resistance corresponding to the operation of the plate operation; if the mechanical position and the electrical position of the plate are consistent, determining the current plate position of the substation operation plate based on the mechanical position of the plate, so as to verify whether the current plate position matches the position requirement before or after the execution of the control command. Therefore, only when the mechanical position of the pressure plate corresponding to the detection switch position of the pressure plate rotation limit switch is consistent with the electrical position of the pressure plate corresponding to the detection resistance of the pressure plate rotation resistance, is the current pressure plate position of the substation's engagement / disengagement pressure plate determined using the mechanical position of the pressure plate. This ensures the reliability of verifying whether the current pressure plate position of the substation's engagement / disengagement pressure plate matches the position requirements before or after the execution of the engagement / disengagement control command. Consequently, the control reliability of the substation's engagement / disengagement pressure plate can be ensured subsequently.

[0063] In one embodiment, determining the mechanical position of the pressure plate based on the difference between the position of the detection switch and the reference switch position corresponding to the pressure plate engagement / disengagement operation includes: calculating a first difference between the position of the detection switch and the reference switch position corresponding to the pressure plate engagement / disengagement operation; dividing the first difference by the reference position to obtain the mechanical position of the pressure plate, wherein the pressure plate engagement / disengagement operation is a pressure plate engagement operation or a pressure plate disengagement operation.

[0064] For example, the mechanical position of the pressure plate is obtained by subtracting the detection switch position detected by the electromagnetic encoder from the first reference switch position detected by the electromagnetic encoder when the pressure plate is engaged, and then dividing the difference by the first reference switch position. Alternatively, the mechanical position of the pressure plate is obtained by subtracting the detection position detected by the electromagnetic encoder from the second reference switch position detected by the electromagnetic encoder when the pressure plate is disengaged. This mechanical position of the pressure plate can be understood as the relative mechanical position of the pressure plate.

[0065] For example, Mech_Result = |Position_Ref - Position_Mech| / Position_Ref, where Mech_Result represents the mechanical position of the pressure plate, Position_Ref represents the first reference switch position or the second reference switch position, and Position_Mech represents the detection switch position.

[0066] For example, after obtaining the mechanical position of the pressure plate, the following operations can be performed:

[0067] For example, the mechanical position Mech_Result of the pressure plate is compared with the position of the first reference switch corresponding to the pressure plate engagement operation. If the difference between the two is within 0.1, the current pressure plate position is determined to be the pressure plate engagement position; for example, the mechanical position judgment flag Position_MechJudge=1. Otherwise, the current pressure plate position is determined to be the pressure plate disengagement position; for example, the mechanical position judgment flag Position_MechJudge=0.

[0068] For example, the mechanical position Mech_Result of the pressure plate is compared with the position of the second reference switch corresponding to the pressure plate exit operation. If the difference between the two is within 0.1, the current pressure plate position is determined to be the pressure plate exit position; for example, the mechanical position judgment flag Position_MechJudge=0. Otherwise, the current pressure plate position is determined to be the pressure plate engagement position; for example, the mechanical position judgment flag Position_MechJudge=1.

[0069] According to the above implementation method, the numerical representation of the mechanical position of the pressure plate can be accurately determined.

[0070] In one embodiment, determining the electrical position of the pressure plate based on the difference between the detection resistor and the reference resistor corresponding to the pressure plate engagement / disengagement operation includes: calculating a second difference between the detection resistor and the first reference resistor corresponding to the fully engaged position of the pressure plate; calculating a third difference between the second reference resistor and the first reference resistor corresponding to the fully disengaged position of the pressure plate; and determining the ratio of the second difference to the third difference as the electrical position of the pressure plate.

[0071] For example, the resistance being detected is the resistance value of the resistance wire in the resistance measurement circuit connected in series with the pressure rotation, i.e., for... Figure 4 or Figure 5 The resistance value detected by the resistance wire in the circuit.

[0072] For example, the electrical position of the pressure plate can be understood as the relative electrical position of the pressure plate, as follows:

[0073] Ele_Result=(R-R_min) / (R_max-R_min);

[0074] Where Ele_Result represents the electrical position of the pressure plate, R represents the detection resistor, R_min represents the first reference resistor corresponding to the fully engaged position of the pressure plate, and R_max represents the second reference resistor corresponding to the fully disengaged position of the pressure plate.

[0075] For example, after obtaining the electrical position of the pressure plate, the following operations can be performed:

[0076] For example, the electrical position Ele_Result of the pressure plate is compared with the first reference position corresponding to the pressure plate engagement operation. If the difference between the electrical position Ele_Result of the pressure plate and the first reference position corresponding to the pressure plate engagement operation is within 0.05, then the current pressure plate position is determined to be the pressure plate engagement position, and the electrical position judgment flag Position_EleJudge=1; otherwise, the current pressure plate position is determined to be the pressure plate disengagement position, and the electrical position judgment flag Position_EleJudge=0.

[0077] For example, the electrical position Ele_Result of the pressure plate is compared with the second reference position corresponding to the pressure plate exit operation. If the difference between the electrical position Ele_Result of the pressure plate and the second reference position corresponding to the pressure plate exit operation is within the range of 0.05, then the current pressure plate position is determined to be the pressure plate exit position, and the electrical position judgment flag Position_EleJudge=0; otherwise, the current pressure plate position is determined to be the pressure plate engagement position, and the electrical position judgment flag Position_EleJudge=1.

[0078] According to the above implementation method, the numerical representation of the electrical position of the pressure plate can be accurately determined.

[0079] In one embodiment, the consistency between the mechanical position and electrical position of the pressure plate can be determined by checking whether the electrical position determination flag and the mechanical position determination flag are consistent.

[0080] In one embodiment, the consistency between the mechanical position and the electrical position of the pressure plate can be determined by the following method. Specifically, the method further includes: calculating the product between the mechanical position and a preset first angle to obtain the mechanical angle of the pressure plate; calculating the product between the electrical position and the first angle to obtain the electrical angle of the pressure plate; determining that the mechanical position and the electrical position of the pressure plate are consistent if the angle difference between the mechanical angle and the electrical angle is less than a preset angle threshold; and determining that the mechanical position and the electrical position of the pressure plate are inconsistent if the angle difference between the mechanical angle and the electrical angle is greater than the angle threshold.

[0081] For example, since the range of the pressure plate rotation angle is to Therefore, the mechanical angle of the pressure plate can be The electrical angle of the pressure plate can be .

[0082] For example, when If the mechanical position of the pressure plate is inconsistent with its electrical position, then the mechanical position of the pressure plate is determined to be inconsistent with its electrical position; otherwise, the mechanical position of the pressure plate is determined to be consistent with its electrical position.

[0083] According to the above implementation method, the difference between the mechanical angle and the electrical angle of the pressure plate can be used to determine whether the mechanical position and the electrical position of the pressure plate are consistent.

[0084] In one embodiment, the method further includes: when the mechanical position and electrical position of the pressure plate are inconsistent, performing temperature compensation on the rotation resistance of the pressure plate and obtaining the temperature-compensated detection resistance; based on the temperature-compensated detection resistance, returning to the step of determining the electrical position of the pressure plate based on the difference between the detection resistance and the reference resistance corresponding to the pressure plate engagement / disengagement operation, to obtain an updated pressure plate electrical position; when the mechanical position and the updated pressure plate electrical position are consistent, determining the current pressure plate position of the substation engagement / disengagement pressure plate based on the mechanical position; when the mechanical position and the updated pressure plate electrical position are inconsistent, generating a first alarm message, wherein the first alarm message is used to indicate that the mechanical position and electrical position of the substation engagement / disengagement pressure plate are inconsistent.

[0085] For example, the temperature compensation for the rotational resistance of the pressure plate can be achieved in the following manner:

[0086] ;

[0087] in, This indicates the detection resistor for the rotation resistance of the pressure plate after temperature compensation. This indicates the detection resistor for the rotation resistance of the pressure plate at an ambient temperature of 25℃. Indicates the current ambient temperature. This indicates that the ambient temperature is 25℃, where, This is the temperature coefficient, for example, it can be 0.0039 / ℃.

[0088] In this example, the resistance value detected for the pressure plate rotation resistor at an ambient temperature of 25°C is corrected to obtain the actual resistance value of the pressure plate rotation resistor at the actual ambient temperature.

[0089] For example, the electrical position of the pressure plate is re-determined based on the difference between the temperature-compensated detection resistor and the reference resistor corresponding to the pressure plate engagement / disengagement operation, resulting in an updated electrical position of the pressure plate. The method for re-determining the electrical position of the pressure plate is the same as the initial determination, as detailed in the aforementioned example.

[0090] For example, after obtaining the updated electrical position of the pressure plate, it can be determined whether the mechanical position of the pressure plate is consistent with the updated electrical position of the pressure plate, based on the aforementioned example of determining whether the mechanical position of the pressure plate is consistent with the electrical position of the pressure plate.

[0091] For example, after temperature compensation, if the mechanical position of the pressure plate is still inconsistent with its electrical position, it indicates an abnormality in the pressure plate rotation mechanism, and a first alarm message can be generated. This first alarm message indicates that the mechanical position of the pressure plate in the substation's engagement / disengagement mechanism is inconsistent with its electrical position. Simultaneously, the position indicator on the pressure plate device can flash yellow to indicate an abnormality in the pressure plate rotation mechanism.

[0092] According to the above implementation method, when it is initially determined that the mechanical position and electrical position of the pressure plate are inconsistent, temperature compensation is performed on the rotation resistance of the pressure plate, and then the electrical position of the pressure plate is recalculated. The mechanical and electrical positions of the pressure plate are then checked again to see if they are consistent. If they are consistent, the current pressure plate position for the substation's on / off pressure plate is determined based on the mechanical position. This provides a reliable current pressure plate position. Furthermore, if an inconsistency is again determined, corresponding alarm information is generated to provide maintenance personnel with information for pressure plate inspection.

[0093] In one embodiment, determining the current position of the substation engagement / disengagement engagement plate based on the mechanical position of the engagement plate includes: if the difference between the mechanical position of the engagement plate and the first reference switch position corresponding to the fully engaged position of the engagement plate is less than a preset first difference threshold, initially determining the current position of the engagement plate as the engagement position; if the current position of the engagement plate is initially determined to be the engagement position, detecting the first conduction resistance between the upper and lower contacts of the lower conductive sheet of the engagement plate; if the first conduction resistance is less than a preset first resistance threshold, again determining the current position of the engagement plate as the engagement position; if the first conduction resistance is greater than the first resistance threshold, generating a first alarm message, wherein the first alarm message is used to indicate that the mechanical position and electrical position of the engagement plate of the substation engagement / disengagement engagement plate are inconsistent.

[0094] Understandably, the upper and lower contacts can be upper stationary contacts and lower stationary contacts, or upper moving contacts and lower moving contacts.

[0095] For example, the mechanical position Mech_Result of the pressure plate is compared with the position of the first reference switch corresponding to the pressure plate input operation. If the difference between the two is within the range of 0.1, the current pressure plate position is determined to be the pressure plate input position, for example, the mechanical position judgment flag Position_MechJudge=1; otherwise, the current pressure plate position is determined to be the pressure plate exit position, for example, the mechanical position judgment flag Position_MechJudge=0.

[0096] In this example, the value of the mechanical position judgment flag can be used to determine whether the difference between the mechanical position of the pressure plate and the first reference switch position corresponding to the fully engaged position of the pressure plate is less than a preset first difference threshold. Thus, it can be preliminarily determined whether the current pressure plate position of the substation's engagement / disengagement pressure plate is the pressure plate engaged position.

[0097] For example, if the first on-resistance R1 is less than 30mΩ, the current position of the substation engagement / disengagement pressure plate is determined again as the engagement position. If the first on-resistance R1 is greater than 30mΩ, a first alarm message is generated, which indicates that the mechanical position and electrical position of the substation engagement / disengagement pressure plate are inconsistent.

[0098] In one embodiment, determining the current position of the substation engagement / disengagement engagement plate based on the mechanical position of the engagement plate includes: if the numerical difference between the mechanical position of the engagement plate and the second reference switch position corresponding to the fully disengaged position of the engagement plate is less than a preset second difference threshold, initially determining the current position of the engagement / disengagement engagement plate as the engagement plate disengagement position, and detecting the voltage difference between the upper and lower contacts of the upper layer of the engagement / disengagement engagement plate; if the voltage difference between the upper and lower contacts of the upper conductive sheet of the engagement / disengagement engagement plate is less than a preset voltage difference threshold, detecting the second conduction resistance between the upper and lower contacts of the lower conductive sheet of the engagement / disengagement engagement plate; if the second conduction resistance is greater than a preset second resistance threshold, again determining the current position of the engagement / disengagement engagement plate as the engagement plate disengagement position; if the second conduction resistance is less than the second resistance threshold, generating a first alarm message, wherein the first alarm message is used to indicate that the mechanical position and electrical position of the engagement / disengagement engagement plate are inconsistent.

[0099] Understandably, the upper contact and the lower contact are the upper moving contact and the lower moving contact.

[0100] For example, the mechanical position Mech_Result of the pressure plate is compared with the position of the second reference switch corresponding to the pressure plate exit operation. If the difference between the two is within the range of 0.1, the current pressure plate position is determined to be the pressure plate exit position, for example, the mechanical position judgment flag Position_MechJudge=0; otherwise, the current pressure plate position is determined to be the pressure plate entry position, for example, the mechanical position judgment flag Position_MechJudge=1.

[0101] In this example, the value of the mechanical position judgment flag can be used to determine whether the difference between the mechanical position of the pressure plate and the first reference switch position corresponding to the fully retracted position of the pressure plate is less than a preset second difference threshold. Thus, it can be preliminarily determined whether the current pressure plate position of the substation's pressure plate is the pressure plate retracted position.

[0102] For example, while determining the current position of the substation engagement / disengagement plate as the plate disengagement position, the voltage difference between the upper and lower moving contacts of the upper conductive sheet of the substation engagement / disengagement plate is detected. If the voltage difference is less than a preset voltage difference threshold, it is determined that the voltage at both ends of the plate meets the voltage requirements for the plate disengagement operation, and thus, the next step of the operation can be continued.

[0103] For example, if the second on-resistance R2 is greater than 1000Ω, the current position of the substation on / off switch is determined again as the switch-off position. If the second on-resistance R2 is less than 1000Ω, a first alarm message is generated, which indicates that the mechanical position and electrical position of the substation on / off switch are inconsistent.

[0104] According to the above implementation method, when the mechanical position and electrical position of the pressure plate are consistent, the current pressure plate position of the substation activation / deactivation pressure plate can be initially determined based on the mechanical position. Then, the current pressure plate position is determined again by the conduction resistance between the upper and lower contacts of the lower conductive sheet of the substation activation / deactivation pressure plate. Thus, by determining the current pressure plate position of the substation activation / deactivation pressure plate in a dual manner, the reliability of the current pressure plate position can be improved.

[0105] In one embodiment, the method further includes: generating a second alarm message when the voltage difference between the upper and lower contacts of the upper conductive sheet of the substation activation / deactivation pressure plate is greater than a voltage difference threshold, wherein the second alarm message is used to indicate that the voltage difference between the upper and lower contacts of the upper conductive sheet of the substation activation / deactivation pressure plate does not meet the voltage requirements for the pressure plate deactivation operation.

[0106] Understandably, the upper contact and the lower contact are the upper moving contact and the lower moving contact.

[0107] For example, if the voltage difference between the upper and lower moving contacts of the upper conductor plate of the substation activation / deactivation pressure plate is greater than the voltage difference threshold, a second alarm message is generated, and the abnormal status indicator light is controlled to flash simultaneously.

[0108] Understandably, while generating the corresponding alarm information, if the activation / deactivation control command is executed before it is executed, the execution of the activation / deactivation control command will be suspended. If the activation / deactivation control command is executed after it is executed, a corresponding alarm indication will be generated, indicating that the aforementioned pressure plate activation / deactivation operation is in an abnormal state.

[0109] According to the above implementation method, if the voltage difference between the upper and lower contacts of the upper conductive plate of the substation activation / deactivation pressure plate is greater than the voltage difference threshold, a second alarm message is generated to indicate that the voltage difference between the upper and lower contacts of the upper conductive plate of the substation activation / deactivation pressure plate does not meet the voltage requirements for the pressure plate deactivation operation, which can facilitate maintenance personnel to carry out maintenance.

[0110] like Figure 6 and Figure 7 As shown, the following position verification operations can be performed before or after the pressure plate deployment / retraction operation, as detailed below:

[0111] First, determine the quantization value Position_ref of the reference switch position corresponding to the pressure plate engagement / disengagement command. When engaging, the quantization value Position_ref of the reference switch position is 128, and when disengaging, the quantization value Position_ref of the reference switch position is 0.

[0112] Then, the quantized value Position_Mech of the electromagnetic encoder's detection switch position is read, and the mechanical position of the pressure plate, Mech_Result = (128 - Position_Mech) / 128, is calculated. The mechanical position of the pressure plate determines whether it is in the engaged or disengaged state. For example, it checks if 128 - Position_Mech is less than 10. If it is, the pressure plate is in the engaged state, and the mechanical position indicator Position_MechJudge = 1; otherwise, it is in the disengaged state, and the mechanical position indicator Position_MechJudge = 0. When the pressure plate is determined to be in the disengaged state, the voltage V_1th of the upper moving contact and the voltage V_2th of the lower moving contact on the upper conductive sheet of the pressure plate are detected, and the voltage difference between them is displayed on an LCD digital display. Determine the voltage difference between the upper and lower moving contacts of the upper conductive sheet on the pressure plate. Is it less than the set voltage difference threshold? If the voltage difference is less than the set voltage difference threshold, it is determined that the voltage across the pressure plate meets the voltage requirements for pressure plate exit operation. Otherwise, the abnormal status indicator light flashes, and an alarm message "The voltage across the pressure plate does not meet the voltage requirements for pressure plate exit operation" is output.

[0113] Next, if the mechanical position of the pressure plate determines that the pressure plate is in the engaged state or in the disengaged state, and the voltage across the pressure plate meets the voltage requirements for the pressure plate disengagement operation, then the resistance value R of the resistance wire in the resistance measurement circuit is read to proceed with the next step.

[0114] In the next step, such as Figure 7As shown, the resistance value of the resistance wire in the voltage measurement circuit is read, and the electrical position of the pressure plate is calculated as Ele_Result = (R - R_min) / (R_max - R_min). The electrical position of the pressure plate determines whether it is in the engaged or disengaged state. Judgment If the condition is met, the pressure plate is initially determined to be in the engaged state, and the pressure plate electrical position identifier Position_EleJudge=1; otherwise, the pressure plate is initially determined to be in the disengaged state, and the pressure plate electrical position identifier Position_EleJudge=0.

[0115] Next, it checks whether the mechanical position judgment flag Position_MechJudge is the same as the electrical position judgment flag Position_MechJudge. If the mechanical position judgment flag Position_MechJudge is different from the electrical position judgment flag Position_MechJudge, the temperature compensation program is started.

[0116] If the mechanical position judgment flag and the electrical position judgment flag are the same, continue measuring the continuity resistance between the upper and lower moving contacts of the lower conductive sheet of the pressure plate. If the pressure plate is in the engaged state and the continuity resistance R1 is less than 30mΩ, output the message "Pressure plate is indeed in the engaged position". If the pressure plate is in the engaged state, but the continuity resistance R1 is not less than 30mΩ, output the alarm message "Pressure plate mechanical position does not match pressure plate electrical position". If the pressure plate is in the disengaged state and the continuity resistance R2 is greater than 1000Ω, output the message "Pressure plate is indeed in the disengaged position". If the pressure plate is in the disengaged state and the continuity resistance R2 is not greater than 1000Ω, output the message "Pressure plate mechanical position does not match pressure plate electrical position".
