Abstract
Description
Technical Field
[0001] This invention relates to the field of preventing misoperation of secondary power equipment, and more specifically, to a method and system for preventing misoperation by pressure plate interlocking. Background Technology
[0002] Secondary power supply circuit breakers are core operating components of substation relay protection. Their on / off status directly determines the logical validity of grid fault diagnosis, protection actions, and equipment start-up and shutdown. The standardization and accuracy of circuit breaker on / off operations are directly related to the safe and stable operation of the power system. In the process of power operation and maintenance, problems such as erroneous on / off operation, missed on / off operation, and delayed updates of operation logs are important causes of relay protection failure to operate, erroneous operation, expansion of grid faults, and abnormal equipment operation. Therefore, the prevention and control of erroneous operation of secondary power supply circuit breakers is a core link in the safe operation and maintenance of power secondary circuit breakers.
[0003] Currently, the traditional operation of secondary pressure plates relies entirely on manual completion and confirmation. The overall operation process lacks automated and intelligent verification and monitoring methods, resulting in many inherent technical defects. Under the existing operation mode, maintenance personnel rely entirely on manual experience and paper and electronic operation tickets to carry out pressure plate operation. During the execution process, the computer key and intelligent management host cannot verify in real time whether the on-site operation matches the preset anti-misoperation logic and standardized operation steps, nor can they determine the compliance and accuracy of the operation behavior in real time. At the same time, after the on-site pressure plate operation is completed, the back-end upper computer ledger system cannot synchronously complete the status alignment and data update. The actual status of the pressure plate on-site and the back-end ledger data have long been inconsistent. The entire operation process has great human operation risks, status control blind spots and safety hazards, making it difficult to meet the control requirements of refined and safe operation and maintenance of the power system.
[0004] Therefore, it is necessary to propose a pressure plate anti-misoperation interlocking control method and system to solve the above problems. Summary of the Invention
[0005] To overcome at least one of the defects (deficiencies) of the prior art described above, the present invention provides a pressure plate anti-misoperation locking control method and system.
[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: a pressure plate anti-misoperation interlocking control method, comprising the following steps: Step 1: After the intelligent management host reads the operation ticket information issued by the host computer, it confirms the status of the pressure plate mentioned in the operation ticket through the pressure plate anti-misoperation interlocking device, and sends the status of the pressure plate to the host computer. If the current status of the pressure plate is correct, the corresponding pressure plate anti-misoperation interlocking device will give an indication of the current pressure plate's open / closed status. If the status of the pressure plate is incorrect, the corresponding pressure plate anti-misoperation interlocking device will give an indication of the current pressure plate's abnormal status. Step 2: The pressure plate anti-misoperation locking device, which displays an indication that the current pressure plate is in an abnormal state, prohibits further operation until the abnormal state indication is cleared. If the pressure plate is in a correct state, the pressure plate anti-misoperation locking device will prompt the intelligent management host or the operator holding the computer key to continue operation. Step 3: The intelligent management host or the operator holding the computer key unlocks the pressure plate according to the instructions issued by the host computer, and sends the unlocking status of the pressure plate after unlocking. The intelligent management host confirms the unlocking status of the pressure plate. Step 4: After the operator controls the pressure plate to open or close according to the instructions on the operation ticket, the pressure plate anti-misoperation locking device sends the current status of the pressure plate, and the intelligent management host or the computer key held by the operator confirms the current status of the pressure plate. Step 5: After the intelligent management host or the operator with the computer key locks the pressure plate, the pressure plate anti-misoperation locking device confirms the locking status of the pressure plate and sends the current status of the pressure plate to the host computer.
[0007] Furthermore, in step 1, the pressure plate anti-misoperation interlocking device is equipped with a closed position indicator light, a closed position indicator light, and an abnormal status indicator light. If the initial state of the pressure plate on the operation ticket is consistent with the actual state of the pressure plate, the current state of the pressure plate is determined to be correct. The pressure plate anti-misoperation interlocking device illuminates the corresponding closed position indicator light or the closed position indicator light according to the current closed or open state of the pressure plate. If the initial state of the pressure plate on the operation ticket is inconsistent with the actual state of the pressure plate, the current state of the pressure plate is determined to be incorrect, and the abnormal status indicator light illuminates in the corresponding pressure plate anti-misoperation interlocking device.
[0008] Furthermore, in step 2, the pressure plate anti-misoperation locking device is assigned an RFID code value for each of the pressure plate's closed locking state, closed unlocking state, open unlocking state, and open locking state. The pressure plate anti-misoperation locking device sends the RFID code value to the intelligent management host and the computer key inserted into the pressure plate anti-misoperation locking device, respectively, or the intelligent management host and the computer key actively read the RFID code value. The intelligent management host and the computer key inserted into the pressure plate anti-misoperation locking device interpret the RFID code value to obtain the current status of the pressure plate.
[0009] Furthermore, in step 3, the intelligent management host unlocks the pressure plate using remote control. The host computer sends a remote control command to open or close the pressure plate. After receiving the remote control command, the intelligent management host sends an unlocking command to the pressure plate anti-misoperation locking device. After the pressure plate anti-misoperation locking device automatically unlocks the pressure plate, it sends the unlocking status of the pressure plate to the intelligent management host, which then confirms the unlocking status of the pressure plate.
[0010] Furthermore, in step 3, when unlocking the pressure plate using the computer key, the operator turns the computer key to perform the unlocking operation. After unlocking, the computer key confirms the current unlocking status of the pressure plate and provides a voice prompt to continue the operation. At the same time, the pressure plate anti-misoperation locking device sends the current unlocking status, and the operator then reverses the key to remove it.
[0011] Furthermore, in step 4, when the operator holding the computer key controls the pressure plate to open or close according to the instructions on the operation ticket, the illumination status of the close status indicator and the open status indicator on the pressure plate anti-misoperation locking device switches, the pressure plate anti-misoperation locking device sends the current status of the pressure plate, and the intelligent management host or the computer key held by the operator confirms the current status of the pressure plate.
[0012] Furthermore, in step 5, when the intelligent management host locks the pressure plate via remote control, after confirming that the pressure plate has been operated to the open or closed position according to the instructions on the operation ticket, the intelligent management host issues a locking command to the pressure plate anti-misoperation locking device. After the pressure plate anti-misoperation locking device automatically locks, it confirms the locking status of the pressure plate and sends the current status of the pressure plate to the host computer.
[0013] Furthermore, in step 5, when locking the pressure plate using the computer key, the operator inserts the computer key to read the current status of the pressure plate and confirms the status of the pressure plate. After the operator locks the pressure plate using the computer key, the pressure plate anti-misoperation locking device confirms the locking status of the pressure plate and sends the current status of the pressure plate to the host computer. The operator then removes the computer key.
[0014] Furthermore, in step 6, after the operation of the pressure plate and the pressure plate anti-misoperation interlocking device is completed, the intelligent management host sends an extinguishing command to the current pressure plate anti-misoperation interlocking device, and the closed and open status indicator lights on the pressure plate anti-misoperation interlocking device are turned off.
[0015] In this invention, a pressure plate anti-misoperation locking control system is also disclosed, comprising a host computer, an intelligent management host, a computer key, a pressure plate anti-misoperation locking device, a pressure plate, and a pressure plate detector for detecting the opening and closing position of the pressure plate. The host computer communicates with the pressure plate anti-misoperation locking device through the intelligent management host and computer key; The pressure plate is designed to open and close to control the on / off state of the circuit. The pressure plate anti-misoperation locking device limits the rotation of the pressure plate after locking. The pressure plate detector is connected to the pressure plate anti-misoperation locking device; The pressure plate detector is connected to the pressure plate anti-misoperation locking device.
[0016] Compared with the prior art, the beneficial effects of the technical solution of the present invention are: The pressure plate anti-misoperation interlocking control method disclosed in this invention effectively solves many technical defects and safety hazards in traditional manual operation of secondary pressure plates, such as unmonitorable status, weak anti-misoperation constraints, loose operation control, and poor system linkage. It significantly improves the safety, intelligence, and standardization of secondary pressure plate operation. The system can accurately collect and transmit four working states of the pressure plate in real time: closed-position interlocking, closed-position unlocking, open-position unlocking, and open-position interlocking. It dynamically tracks changes in the pressure plate status, completely solving the problems of unreal-time perception of pressure plate status, untimely alignment of back-end ledgers, and inconsistent status of diagrams in the traditional mode. It achieves full-time visual control of the pressure plate status. Furthermore, this system comprehensively incorporates the four operating states of the pressure plate into the real-time verification system of anti-misoperation logic, abandoning the weak constraint anti-misoperation mode that relies solely on audible and visual prompts. It achieves physical mandatory interlocking of the pressure plate operation, and, in conjunction with a computer key, completes multi-dimensional... The system confirms the status and verifies the anti-misoperation logic in real time throughout the entire process. Coupled with intelligent operation guidance and real-time result confirmation, it eliminates the risk of incorrect operation of the pressure plate from the technical root. At the operation control level, the system strictly implements a closed-loop operation process of "confirmation-unlocking-confirmation-operation-confirmation-locking-confirmation," making the pressure plate engagement and disengagement operation process standardized, controllable, and traceable. In addition, the system supports a remote control operation mode for pressure plate locking, forming a dual guarantee mechanism of "human-machine dual confirmation" combined with manual verification. It also establishes a two-way operation result transmission channel between the host computer and the computer key, completing a closed-loop dual confirmation for the entire operation process. This not only makes up for the shortcomings of traditional manual operation—no verification, no feedback, and no closed loop—but also achieves deep integration of pressure plate misoperation prevention with the monitoring backend, one-click sequential control, and programmed anti-misoperation logic, comprehensively improving the safety control level and intelligent operation and maintenance level of substation secondary equipment.

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The technical solution of this invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] like Figure 1 As shown, a method for preventing misoperation and interlocking of a pressure plate includes the following steps: Step 1: After the intelligent management host reads the operation ticket information issued by the host computer, it confirms the status of the pressure plate mentioned in the operation ticket through the pressure plate anti-misoperation interlocking device, and sends the status of the pressure plate to the host computer. If the current status of the pressure plate is correct, the corresponding pressure plate anti-misoperation interlocking device will give an indication of the current pressure plate's open / closed status. If the status of the pressure plate is incorrect, the corresponding pressure plate anti-misoperation interlocking device will give an indication of the current pressure plate's abnormal status. Step 2: The pressure plate anti-misoperation locking device, which displays an indication that the current pressure plate is in an abnormal state, prohibits further operation until the abnormal state indication is cleared. If the pressure plate is in a correct state, the pressure plate anti-misoperation locking device will prompt the intelligent management host or the operator holding the computer key to continue operation. Step 3: The intelligent management host or the operator holding the computer key unlocks the pressure plate according to the instructions issued by the host computer, and sends the unlocking status of the pressure plate after unlocking. The intelligent management host confirms the unlocking status of the pressure plate. Step 4: After the operator controls the pressure plate to open or close according to the instructions on the operation ticket, the pressure plate anti-misoperation locking device sends the current status of the pressure plate, and the intelligent management host or the computer key held by the operator confirms the current status of the pressure plate. Step 5: After the intelligent management host or the operator with the computer key locks the pressure plate, the pressure plate anti-misoperation locking device confirms the locking status of the pressure plate and sends the current status of the pressure plate to the host computer.
[0023] In step 1 of this invention, the pressure plate anti-misoperation interlocking device is equipped with a closed position indicator light, a closed position indicator light, and an abnormal status indicator light. If the initial state of the pressure plate on the operation ticket is consistent with the actual state of the pressure plate, the current state of the pressure plate is determined to be correct. The pressure plate anti-misoperation interlocking device illuminates the corresponding closed position indicator light or the closed position indicator light according to the current closed or open state of the pressure plate. If the initial state of the pressure plate on the operation ticket is inconsistent with the actual state of the pressure plate, the current state of the pressure plate is determined to be incorrect, and the abnormal status indicator light illuminates in the corresponding pressure plate anti-misoperation interlocking device.
[0024] In step 2 of this invention, the pressure plate anti-misoperation locking device assigns an RFID code value to each of the pressure plate's closed-lock state, closed-unlock state, open-unlock state, and open-lock state. The pressure plate anti-misoperation locking device sends the RFID code value to the intelligent management host and the computer key inserted into the pressure plate anti-misoperation locking device, or the intelligent management host and the computer key actively read the RFID code value. After the intelligent management host and the computer key inserted into the pressure plate anti-misoperation locking device interpret the RFID code value, they know the current state of the pressure plate.
[0025] In step 3 of this invention, the intelligent management host unlocks the pressure plate using remote control. The host computer sends a remote control command to open or close the pressure plate. After receiving the remote control command, the intelligent management host sends an unlocking command to the pressure plate anti-misoperation locking device. After the pressure plate anti-misoperation locking device automatically unlocks the pressure plate, it sends the unlocking status of the pressure plate to the intelligent management host. The intelligent management host confirms the unlocking status of the pressure plate.
[0026] In step 3 of this invention, when the pressure plate is unlocked using the computer key, the operator turns the computer key to perform the unlocking operation. After the unlocking is complete, the computer key confirms the current unlocking status of the pressure plate and provides a voice prompt to continue the operation. At the same time, the pressure plate anti-misoperation locking device sends the current unlocking status, and the operator then reverses the key to remove it.
[0027] In step 4 of this invention, when the operator controls the pressure plate to open or close according to the instructions on the operation ticket, the lighting status of the close status indicator and the open status indicator on the pressure plate anti-misoperation locking device switches, the pressure plate anti-misoperation locking device sends the current status of the pressure plate, and the intelligent management host or the computer key held by the operator confirms the current status of the pressure plate.
[0028] In step 5 of this invention, when the intelligent management host locks the pressure plate through remote control, after confirming that the pressure plate is operated to the open or closed position according to the operation ticket, the intelligent management host issues a locking command to the pressure plate anti-misoperation locking device. After the pressure plate anti-misoperation locking device automatically locks, it confirms the locking status of the pressure plate and sends the current status of the pressure plate to the host computer.
[0029] In step 5 of this invention, when locking the pressure plate with the computer key, the operator inserts the computer key to read the current status of the pressure plate and confirms the status of the pressure plate. After the operator locks the pressure plate with the computer key, the pressure plate anti-misoperation locking device confirms the locking status of the pressure plate and sends the current status of the pressure plate to the host computer. The operator then takes out the computer key.
[0030] In step 6 of this invention, after the operation of the pressure plate and the pressure plate anti-misoperation interlocking device is completed, the intelligent management host sends an extinguishing command to the current pressure plate anti-misoperation interlocking device, and the closed and open status indicator lights on the pressure plate anti-misoperation interlocking device are extinguished.
[0031] like Figure 2 As shown, this invention also discloses a pressure plate anti-misoperation interlocking control system, including a host computer 1, an intelligent management host 2, a computer key 3, a pressure plate anti-misoperation interlocking device 4, a pressure plate 5, and a pressure plate detector 6 for detecting the opening and closing position of the pressure plate 5; the host computer 1 communicates with the pressure plate anti-misoperation interlocking device 4 through the intelligent management host 2 and the computer key 3; the pressure plate 5, through its openable and closable setting, is used to control the on / off state of the circuit; after locking, the pressure plate anti-misoperation interlocking device 4 limits the rotation of the pressure plate 5; the pressure plate detector 6 is connected to the pressure plate anti-misoperation interlocking device 4. Example
[0032] After the intelligent management host reads the operation ticket information issued by the host computer, it confirms the status of the pressure plate mentioned in the operation ticket through the pressure plate anti-misoperation interlocking device and sends the status of the pressure plate to the host computer. If the current pressure plate status is correct, the corresponding pressure plate anti-misoperation interlocking device will give an indication of the current pressure plate's open / closed status. If the pressure plate status is incorrect, the corresponding pressure plate anti-misoperation interlocking device will give an indication of the current pressure plate's abnormal status. In this invention, the pressure plate anti-misoperation interlocking device is equipped with an open / closed status indicator, an open / closed status indicator, and an abnormal status indicator. If the initial status of the pressure plate on the operation ticket is consistent with the actual status of the pressure plate, the current pressure plate status is determined to be correct. The pressure plate anti-misoperation interlocking device will light up the corresponding open / closed status indicator or the open / closed status indicator according to the current pressure plate's open / closed status. If the initial status of the pressure plate on the operation ticket is inconsistent with the actual status of the pressure plate, the current pressure plate status is determined to be incorrect, and the corresponding pressure plate anti-misoperation interlocking device will light up the abnormal status indicator.
[0033] In this embodiment, the pressure plate anti-misoperation locking device, which indicates that the current pressure plate is in an abnormal state, prohibits further operation until the abnormal state indication is eliminated. If the pressure plate is in a correct state, the anti-misoperation locking device then prompts the intelligent management host or the operator holding the computer key to continue operation. In this invention, the pressure plate anti-misoperation locking device assigns an RFID code value to each of the pressure plate's closed-lock state, closed-unlock state, open-unlock state, and open-lock state. The anti-misoperation locking device sends this RFID code value to the intelligent management host and the computer key inserted into the device, or the intelligent management host and the computer key actively read the RFID code value. After interpreting the RFID code value, the intelligent management host and the computer key can determine the current state of the pressure plate. In this invention, the RFID code value can be read by the intelligent management host or the operator holding the computer key through active or passive means, via contact or network connection.
[0034] When the intelligent management host unlocks the pressure plate remotely, the host computer sends a remote control command to open or close the pressure plate. Upon receiving the command, the intelligent management host sends an unlocking command to the pressure plate anti-misoperation interlocking device. The anti-misoperation interlocking device automatically unlocks the pressure plate and then sends the unlocking status information back to the intelligent management host. The intelligent management host confirms the unlocking status. When the operator controls the pressure plate to open or close according to the operation ticket, the illumination status of the close and open indicator lights on the anti-misoperation interlocking device switches, and the pressure plate anti-misoperation interlocking device... The misoperation prevention interlocking device sends the current status of the pressure plate. The intelligent management host confirms the current status of the pressure plate. After confirming that the pressure plate has been operated to the open or closed position according to the operation ticket instructions, the intelligent management host issues a locking command to the pressure plate misoperation prevention interlocking device. After the pressure plate misoperation prevention interlocking device automatically locks, it confirms the locking status of the pressure plate and sends the current status of the pressure plate to the host computer. After the operation of the pressure plate and the pressure plate misoperation prevention interlocking device is completed, the intelligent management host sends an extinguishing command to the current pressure plate misoperation prevention interlocking device, and the closed and open position status indicator lights on the pressure plate misoperation prevention interlocking device are turned off. Example
[0035] In this embodiment, after the intelligent management host reads the operation ticket information issued by the host computer, it confirms the status of the pressure plate mentioned in the operation ticket through the pressure plate anti-misoperation interlocking device and sends the pressure plate status to the host computer. If the current pressure plate status is correct, the corresponding pressure plate anti-misoperation interlocking device will provide an indication of the current pressure plate's open / closed status. If the pressure plate status is incorrect, the corresponding pressure plate anti-misoperation interlocking device will provide an indication of the current pressure plate's abnormal status. The pressure plate anti-misoperation interlocking device is equipped with an open / closed status indicator, an open / closed status indicator, and an abnormal status indicator. If the initial status of the pressure plate on the operation ticket matches the actual status of the pressure plate, the current pressure plate status is determined to be correct. The pressure plate anti-misoperation interlocking device will illuminate the corresponding open / closed status indicator or the open / closed status indicator according to the current pressure plate's open / closed status. If the initial status of the pressure plate on the operation ticket does not match the actual status of the pressure plate, the current pressure plate status is determined to be incorrect, and the corresponding pressure plate anti-misoperation interlocking device will illuminate an abnormal status indicator. In this embodiment, the pressure plate anti-misoperation locking device, which indicates that the current pressure plate is in an abnormal state, prohibits further operation until the abnormal state indication is eliminated. If the pressure plate is in a correct state, the anti-misoperation locking device then prompts the intelligent management host or the operator holding the computer key to continue operation. In this invention, the pressure plate anti-misoperation locking device assigns an RFID code value to each of the pressure plate's closed-lock, closed-unlock, open-unlock, and open-lock states. The anti-misoperation locking device sends this RFID code value to the intelligent management host and the computer key inserted into the device, or the intelligent management host and the computer key actively read the RFID code value. After interpreting the RFID code value, the intelligent management host and the computer key determine the current state of the pressure plate. In this invention, the RFID code value can be read by the intelligent management host or the operator holding the computer key through active or passive means, via contact or network connection.
[0036] When unlocking the pressure plate using the computer key, the operator turns the key to unlock it. Once unlocked, the computer key confirms the current unlock status of the pressure plate and provides a voice prompt to continue. Simultaneously, the pressure plate anti-misoperation locking device transmits the current unlock status. The operator then reverses the key to retrieve it. When the operator controls the pressure plate to open or close according to the instructions on the operation ticket, the indicator lights for the open and closed positions on the pressure plate anti-misoperation locking device switch between illumination. The anti-misoperation locking device transmits the current status of the pressure plate, and the intelligent management host and the computer key held by the operator are activated. The current status of the pressure plate is confirmed. When locking the pressure plate using the computer key, the operator inserts the computer key to read and confirm the current status of the pressure plate. After the operator locks the pressure plate using the computer key, the pressure plate anti-misoperation locking device confirms the locking status of the pressure plate and sends the current status of the pressure plate to the host computer. The operator removes the computer key. After the operation of the pressure plate and the pressure plate anti-misoperation locking device is completed, the intelligent management host sends an extinguishing command to the current pressure plate anti-misoperation locking device, and the closed and open status indicator lights on the pressure plate anti-misoperation locking device turn off.
