Description

Technical Field

[0001] The present invention belongs to the field of preventing accidental touch of a pressure plate of a control panel cabinet of a substation, and particularly relates to a method and a system for preventing accidental touch of a pressure plate of a control panel cabinet of a substation. Background Art

[0002] The main purpose of the anti-accidental touch method of the pressure plate of the substation control panel cabinet is to prevent operators from accidentally touching or operating the control panel cabinet, thereby ensuring the safety and stability of the system. A protective cover or baffle is installed on the pressure plate area to ensure that key control components are not accidentally touched during operation. Physical protection structures are added around important control buttons, such as increasing the protruding design of the button, or using spring-loaded buttons that can only be triggered after pressing a certain force; in the control panel cabinet, multiple confirmation steps are set, such as pressing multiple buttons continuously before triggering key operations, or requiring the input of an operation password, etc., to prevent accidental operations; for those using The touch screen control cabinet is equipped with a virtual area lock to prevent activation of unrelated accidental touch areas. A hierarchical authority management system is adopted, and only personnel with specific permissions can perform key operations. In this way, even if the operator accidentally touches a button that should not be operated, harmful instructions cannot be executed; obvious warning signs are posted on the panel cabinet or near the buttons to remind operators to operate with caution and avoid accidental touches, ensure that the pressure plate and other key electrical components are well grounded, and avoid the risk of electric shock due to improper operation. Key components such as circuit breakers or transformer control switches can be designed with self-locking functions to ensure that the operator must follow the correct steps to release the locked state.

[0003] However, the existing substation control panel cabinet pressure plate anti-accidental touch method has made many improvements in ensuring safety, but there are still some potential defects and room for improvement. Due to the dense arrangement of operation panels and buttons in the panel cabinet, operators can easily inadvertently touch areas that should not be touched. Especially in high voltage and high current environments, incorrect operation may lead to serious safety accidents. There are currently some anti-accidental touch design methods, such as physical protective covers, permission management, touch screen sensitivity adjustment, etc., but there are still problems such as complex operation, high latency, and inability to adapt to changing environments. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a method and system for preventing accidental touch of the pressure plate of the substation control panel cabinet, effectively improving the accuracy and flexibility of preventing accidental touch, and solving the deficiencies of the prior art through intelligent means.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] The method for preventing accidental touch of the pressure plate of the substation control panel cabinet includes the following steps:

[0007] Step 1: By setting up an infrared sensing area and gesture recognition system, the operator's hand approach position is automatically detected. When the operator's hand moves in front of the control panel cabinet, the system uses infrared sensors and gesture recognition technology to judge the operator's movement and determine whether it is a valid operation;

[0008] Step 2: When the system detects changes in the environmental conditions of the control panel cabinet, it automatically adjusts the touch screen sensitivity and operation feedback mechanism of the panel cabinet. In the case of high humidity or high temperature, the touch screen sensitivity is automatically reduced;

[0009] Step 3: Before a critical operation, the system automatically triggers a multiple confirmation mechanism. The operator confirms the operation intention by clicking the pop-up option button on the touch screen and using voice recognition. For special or high-risk operations, the system pops up a warning message and asks the operator for a second confirmation.

[0010] Step 4: The system dynamically adjusts permissions based on the operator's identity and task requirements. If the operator is a low-privilege person, the system automatically limits their operating permissions to key control components and provides only operating options within the scope of their permissions based on the task type.

[0011] As a preferred method, an infrared sensing area and a gesture recognition system are set up to automatically detect the proximity of the operator's hand. When the operator's hand moves in front of the control panel cabinet, the system uses infrared sensors and gesture recognition technology to judge the operator's action and determine whether it is a valid operation. The method is as follows:

[0012] The infrared sensing system uses a sensor to detect the distance between the hand and the cabinet. The closer the distance, the greater the possibility of triggering the operation. The working principle of the infrared sensor involves the photoelectric sensor detecting the reflection or obstruction of the object, which is expressed by the following formula:

[0013] d hand =f(I received ,I cmitted )

[0014] Among them, d hand is the distance between the hand and the screen cabinet;

[0015] I received is the intensity of the received infrared light;

[0016] I cmitted is the intensity of the emitted infrared light;

[0017] f is the function for calculating distance based on reflection or obstruction;

[0018] The gesture recognition system analyzes the operator's hand movements to determine whether they are valid operations. Gesture recognition technology uses image processing and machine learning methods to determine hand movements, and is described by the following formula:

[0019] gesture valid =g(ΔP,Δt)

[0020] Among them, gesture valid The result of judging whether the gesture is valid, if it is valid, it is 1, if it is invalid, it is 0;

[0021] ΔP is the change in the hand position, indicating whether the hand moves within a certain area;

[0022] Δt is the time interval, indicating the speed of hand movement;

[0023] g is the gesture judgment function based on the dynamic changes of the hand;

[0024] Based on the results of infrared sensing area and gesture recognition, the system uses the following formula to determine whether it is a valid operation:

[0025]

[0026] Among them, operation valid The result of judging whether the operation is valid, if it is valid, it is 1, if it is invalid, it is 0;

[0027] d thrcshold is the trigger threshold of the infrared sensing area;

[0028] gesture valid The result of judging whether the gesture is valid.

[0029] As a preferred method, when the system detects changes in the environmental conditions of the control panel cabinet, it automatically adjusts the touch screen sensitivity and operation feedback mechanism of the panel cabinet. In the case of high humidity or high temperature, the touch screen sensitivity is automatically reduced in the following manner:

[0030] The sensitivity S of the touch screen is set as a function of humidity and temperature, and the formula is:

[0031] S=f(H,T)

[0032] Where S is the touch screen sensitivity;

[0033] H is the current ambient humidity;

[0034] T is the current ambient temperature;

[0035] f is the influence function of environmental conditions on sensitivity;

[0036] Under high temperature and humidity conditions, the touch screen sensitivity will decrease. Adjust the sensitivity according to the following formula:

[0037] S=S base×(1-αH-βT)

[0038] Among them, S base is the basic sensitivity, which is the default sensitivity under normal environmental conditions;

[0039] α and β are adjustment factors, which respectively indicate the degree of influence of humidity and temperature changes on sensitivity;

[0040] α represents the percentage of sensitivity reduction when humidity increases by 1%;

[0041] β represents the reduction ratio of sensitivity when the temperature increases by 1°C;

[0042] H is the current humidity, T is the current temperature;

[0043] The specific operation process is set up as follows:

[0044] Basic sensitivity S base =1.0;

[0045] Adjustment factor α = 0.005;

[0046] Adjustment factor β = 0.01;

[0047] If the current ambient humidity is 80% and the current temperature is 35°C, then:

[0048] S=1.0×(1-0.005×80-0.01×35)

[0049] S=1.0×(1-0.4-0.35)

[0050] S = 1.0 × 0.25 = 0.25

[0051] To avoid excessive reduction in sensitivity, the system sets a minimum sensitivity value S min ,for:

[0052] S=max(S,S min )

[0053] Among them, S min is the minimum acceptable value of sensitivity to prevent abnormal operation due to low sensitivity. The formula is:

[0054] S min =0.1

[0055] If the calculated S is less than S min , the sensitivity is limited to S min .

[0056] As a preference, before a critical operation, the system automatically triggers a multiple confirmation mechanism, and the operator confirms the operation intention through the pop-up option button on the touch screen and through voice recognition. For special or high-risk operations, the system pops up a warning message and asks the operator for a second confirmation. The method is as follows:

[0057] The system triggers a series of confirmation steps before key operations. The confirmation process for setting up an operation includes the following steps:

[0058] The operator performs preliminary confirmation by pressing the button on the touch screen. The validity of the touch screen confirmation is expressed by the following formula:

[0059] touch_confirm=f(button_press,T timcout )

[0060] touch_confirm is the result of touch screen confirmation, if valid, it is 1, if invalid, it is 0;

[0061] button_press is the pressing action of the touch screen button;

[0062] T timcout The timeout parameter for touch screen confirmation, that is, the time after the operator presses the button;

[0063] The voice recognition system confirms the operator's voice. If the operator's voice matches the preset confirmation command, the voice confirmation is valid. The formula is as follows:

[0064] voice_confirm=g(voice_input,command_list)

[0065] voice_confirm is the result of voice confirmation, which is 1 if valid and 0 if invalid;

[0066] voice_input is the operator's voice input;

[0067] command_list is the preset voice command list;

[0068] For special or high-risk operations, the system will pop up a warning message and require secondary confirmation. The formula is as follows:

[0069] risk_warning=h(operation_type,risk_threshold)

[0070] risk_warning is the pop-up result of the warning message, which is 1 if the warning is triggered and 0 if it is not triggered;

[0071] operation_trpe is the operation type;

[0072] risk_threshold is the risk threshold. When the operation type belongs to the high-risk category, a warning pops up;

[0073] After the system pops up a warning, the operator performs a second confirmation:

[0074] secondary_confirm=f(button_press,voice_input,T timcout )

[0075] secondart_confirm is the result of the second confirmation, which is 1 if valid and 0 if invalid;

[0076] T timcout is the timeout threshold for secondary confirmation;

[0077] The entire confirmation process is represented by the following comprehensive formula to ensure multiple verifications before key operations:

[0078]

[0079] Among them, operation_valid is the final confirmation result of whether the operation is valid, which is 1 if it is valid and 0 if it is invalid.

[0080] As a preferred method, the system dynamically adjusts permissions based on the operator's identity and task requirements. If the operator is a low-privilege person, the system automatically limits their operating permissions to key control components and provides only operating options within the scope of their permissions based on the task type. The method is as follows:

[0081] The authority level P of each operator is defined based on their identity. The range of authority levels is divided into several levels. The formula is:

[0082] P = f(operator_role)

[0083] operator_role represents the identity role of the operator;

[0084] P is the operator's permission level, and its value is defined as:

[0085] Low permissions: P low ;

[0086] Medium authority: P medium ;

[0087] High authority: P high ;

[0088] The system determines the scope of the operator's authority based on the current task type T. Each task type corresponds to a permission P. rcquired :

[0089] P required =g(T)

[0090] P required Indicates the minimum permission level required for the current task;

[0091] T is the type of the current task;

[0092] When the operator performs a task, the system dynamically adjusts the scope of the operation according to the operator's authority level and the authority requirements of the task. If the operator's authority level P is lower than the authority required by the task P, the system will automatically adjust the scope of the operation according to the operator's authority level and the authority requirements of the task. required , the system will restrict its access rights to key control components, the formula is as follows:

[0093]

[0094] access_granted is a flag indicating whether the operator is allowed to perform the current task. If the operation is allowed, it is 1; if not, it is 0.

[0095] If the operator's authority is insufficient to perform the current task, the system will restrict the operation of key components and only provide operation options that are within the scope of their authority. The system generates an operation option list O based on the authority level P and task type T. allowed :

[0096] O allowed =h(P,T)

[0097] O allowed A set of operation options generated by the system for the operator;

[0098] h(P, T) is a function that generates operation options based on operator authority and task type;

[0099] For a low-privilege operator, if the task type is a high-risk operation and the operator's permission P low Lower than the required authority P for the task required , the system limits its access to key control components and provides options for granting operations to low-privilege operators;

[0100] The task is set to be a high-risk operation: T = high_risk_operation;

[0101] Operator authority: P low ;

[0102] Task authority requirements: P required =P high ;

[0103] At this time, P low <P required ,therefore:

[0104] access_granted=0

[0105] The system is implemented by formula O alowed =h(P low ,T high_risk_opcration ) Restrict operators to perform operations with low permissions;

[0106] For a high-authority operator, the task type is high-risk operation, and its authority P high Higher than the task required authority P required , the system authorizes the operator to perform the operation and provides complete operation options;

[0107] Set the task as a high-risk operation: T = high_risk_operation;

[0108] Operator authority: P high ;

[0109] Task authority requirements: P required =P high ;

[0110] At this time, P high ≥P required ,therefore:

[0111] access_granted=1

[0112] The system will be based on O allowed =h(P high ,T high_risk_operation ) Provide a complete set of high-risk operation options and authorize the operator to perform the operation;

[0113] In special cases, the system grants temporary enhanced permissions to low-privilege operators to complete tasks. Based on the operator's request and the approval of the superior, the system temporarily increases the permissions and generates a new permission level P temp :

[0114] P temp =P low +ΔP

[0115] ΔP represents the temporary increase in privileges;

[0116] The system is based on the new permission level P temp Reassess the scope of operator authority;

[0117] Before a task is executed, the system will determine whether the operation can be performed based on the operator's permissions and task requirements:

[0118]

[0119] The substation control panel cabinet pressure plate anti-accidental touch system includes:

[0120] Infrared sensing modules are placed around the cabinet panel to detect the proximity and position of the operator's hand in real time. When the operator's hand approaches, the system enables or disables the touch area according to the preset operating conditions.

[0121] The gesture recognition module is used to identify the operator's hand posture and movements through cameras and image recognition technology, and trigger the corresponding operation instructions only when a valid gesture is detected;

[0122] Intelligent adjustment module, which is used to integrate environmental monitoring sensors to sense the humidity, temperature and light intensity of the environment and automatically adjust parameters such as touch screen sensitivity and button response time;

[0123] The voice recognition and feedback module is used to combine voice recognition technology to provide voice confirmation to the operator, ensuring that each operation of the operator is clearly confirmed. The operator initiates control instructions through voice commands, and the system uses voice feedback to ensure that the instructions have been received and executed;

[0124] The permission management module is used to integrate the authentication-based permission management system. All operators confirm their identities through fingerprint recognition, facial recognition or password verification. After identity confirmation, the system automatically sets different permissions according to roles and tasks.

[0125] Another technical problem to be solved by the present invention is to provide an electronic device, including a memory, a processor, and a computer program stored in the memory and runnable on the processor. When the processor executes the program, it implements a method and system for preventing accidental touch of the pressure plate of a substation control panel cabinet as described in any of the above.

[0126] Another technical problem to be solved by the present invention is to provide a computer-readable storage medium on which a computer program is stored. When the program is executed by a processor, a method and system for preventing accidental touch of a pressure plate of a control panel cabinet of a substation is implemented.

[0127] The beneficial effects of the present invention are:

[0128] By automatically detecting the operator's hand approach position, the system ensures that operations are performed only when the operator effectively touches the device; through infrared sensing and gesture recognition technology, the system can dynamically adjust the operation mode according to the operator's movements and environmental changes, allowing the equipment to respond flexibly in different environments and operating scenarios; through gesture recognition, the operator does not have to touch the screen directly, which improves the intuitiveness and convenience of interaction, especially when the environment is not suitable for direct contact with the screen; the system automatically restricts the operation of key control components by low-authority personnel based on the operator's authority, ensuring that only personnel with corresponding authority can perform high-risk operations, thereby reducing potential operational errors and system safety hazards; through the system's automatic sensing and intelligent adjustment, the operator does not need to manually adjust the device or interface, reducing human interference during operation and improving overall work efficiency and operational accuracy; due to the automatic adjustment of the touch screen sensitivity and operation feedback mechanism, the system can adapt to environmental changes such as humidity and temperature, so that it can still operate stably in various unstable or extreme environments, enhancing the reliability of the system.

[0130] The principles and features of the present invention are described below. The examples provided are intended to illustrate the present invention only and are not intended to limit the scope of the present invention. The following paragraphs describe the present invention in more detail by way of example. The advantages and features of the present invention will become more apparent from the following description and claims.

[0131] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0132] Example

[0133] The technical solution adopted by the present invention to solve its technical problem is:

[0134] The method for preventing accidental touch of the pressure plate of the substation control panel cabinet includes the following steps:

[0135] Step 1: By setting up an infrared sensing area and gesture recognition system, the operator's hand approach position is automatically detected. When the operator's hand moves in front of the control panel cabinet, the system uses infrared sensors and gesture recognition technology to judge the operator's movement and determine whether it is a valid operation;

[0136] Step 2: When the system detects changes in the environmental conditions of the control panel cabinet, it automatically adjusts the touch screen sensitivity and operation feedback mechanism of the panel cabinet. In the case of high humidity or high temperature, the touch screen sensitivity is automatically reduced;

[0137] Step 3: Before a critical operation, the system automatically triggers a multiple confirmation mechanism. The operator confirms the operation intention by clicking the pop-up option button on the touch screen and using voice recognition. For special or high-risk operations, the system pops up a warning message and asks the operator for a second confirmation.

[0138] Step 4: The system dynamically adjusts permissions based on the operator's identity and task requirements. If the operator is a low-privilege person, the system automatically limits their operating permissions to key control components and provides only operating options within the scope of their permissions based on the task type.

[0139] This method effectively avoids accidental touches or unnecessary operations. For example, when the operator is just standing near the control panel cabinet without intending to operate, the system will not mistake it for an operation instruction, thereby improving the safety of operation; through multiple confirmation mechanisms, it ensures that each operation of the operator is carefully verified, reducing the risk caused by operator negligence or misunderstanding, especially in high-risk operation links; in environments with high humidity or high temperature, the touch screen sensitivity is automatically reduced, effectively avoiding accidental touches and operational errors caused by environmental factors (such as moisture, dust, etc.); this mechanism can effectively prevent unauthorized personnel from accessing key control components, reduce potential safety risks, and at the same time, through precise authority allocation, ensure the operator's Operators can only perform operations that are consistent with their tasks, thereby improving operational safety and management efficiency; the combination of voice confirmation and gesture recognition technology allows operators to complete operations without a touch screen, which is especially suitable for situations where hands are dirty or protective equipment is worn, improving the convenience and accuracy of interaction; the system can intelligently adapt to environmental changes and does not require operators to make manual adjustments, thus avoiding the impact of human negligence or improper adjustments; when direct touch screen access is not possible or operation is difficult, voice control provides an efficient, contactless operation method, enhancing user experience and operational convenience; double verification reduces the risk of accidental touch operations and ensures that the system only responds to valid and confirmed operation instructions.

[0140] By setting up infrared sensing areas and gesture recognition systems, the operator's hand approach position is automatically detected. When the operator's hand moves in front of the control panel cabinet, the system uses infrared sensors and gesture recognition technology to judge the operator's movements and determine whether they are valid operations. The method is as follows:

[0141] The infrared sensing system uses a sensor to detect the distance between the hand and the cabinet. The closer the distance, the greater the possibility of triggering the operation. The working principle of the infrared sensor involves the photoelectric sensor detecting the reflection or obstruction of the object, which is expressed by the following formula:

[0142] d hand =f(I received ,I cmitted )

[0143] Among them, d hand is the distance between the hand and the screen cabinet;

[0144] I received is the intensity of the received infrared light;

[0145] I cmitted is the intensity of the emitted infrared light;

[0146] f is the function for calculating distance based on reflection or obstruction;

[0147] The gesture recognition system analyzes the operator's hand movements to determine whether they are valid operations. Gesture recognition technology uses image processing and machine learning methods to determine hand movements, and is described by the following formula:

[0148] gesture valid =g(ΔP,Δt)

[0149] Among them, gesture valid The result of judging whether the gesture is valid, if it is valid, it is 1, if it is invalid, it is 0;

[0150] ΔP is the change in the hand position, indicating whether the hand moves within a certain area;

[0151] Δt is the time interval, indicating the speed of hand movement;

[0152] g is the gesture judgment function based on the dynamic changes of the hand;

[0153] Based on the results of infrared sensing area and gesture recognition, the system uses the following formula to determine whether it is a valid operation:

[0154]

[0155] Among them, operation valid The result of judging whether the operation is valid, if it is valid, it is 1, if it is invalid, it is 0;

[0156] d thrcshold is the trigger threshold of the infrared sensing area;

[0157] gesture valid The result of judging whether the gesture is valid.

[0158] The combination of infrared sensing and gesture recognition can accurately determine whether there is a valid operating intention, thereby reducing misoperations caused by carelessness or environmental factors (such as dust, moisture, etc.); by combining gesture recognition and infrared sensing, the system can intelligently determine whether the operator has a valid operating intention; the sensitivity of the infrared sensing system can automatically adjust according to different environmental conditions (such as humidity, temperature, etc.), further enhancing the adaptability of the system; through gesture recognition technology, operators can perform contactless operations more conveniently, especially suitable for environments where gloves are required or there are other operating restrictions; the system can not only accurately sense the operator's hand approach, but also further verify the operating intention through gesture recognition technology, ensuring that the system operates under high-precision control; when comprehensively judging whether the operation is valid, dynamic restrictions can be made in combination with the operator's identity and authority control. Before key operations, the system can use gestures and infrared sensing to double-verify whether the operator has sufficient authority, thereby improving the security of the system and the accuracy of management.

[0159] When the system detects changes in the environmental conditions of the control panel cabinet, it automatically adjusts the touch screen sensitivity and operation feedback mechanism of the panel cabinet. In the case of high humidity or high temperature, the touch screen sensitivity is automatically reduced in the following ways:

[0160] The sensitivity S of the touch screen is set as a function of humidity and temperature, and the formula is:

[0161] S=f(H,T)

[0162] Where S is the touch screen sensitivity;

[0163] H is the current ambient humidity;

[0164] T is the current ambient temperature;

[0165] f is the influence function of environmental conditions on sensitivity;

[0166] Under high temperature and humidity conditions, the touch screen sensitivity will decrease. Adjust the sensitivity according to the following formula:

[0167] S=S base ×(1-αH-βT)

[0168] Among them, S basc is the basic sensitivity, which is the default sensitivity under normal environmental conditions;

[0169] α and β are adjustment factors, which respectively indicate the degree of influence of humidity and temperature changes on sensitivity;

[0170] α represents the percentage of sensitivity reduction when humidity increases by 1%;

[0171] β represents the reduction ratio of sensitivity when the temperature increases by 1°C;

[0172] H is the current humidity, T is the current temperature;

[0173] The specific operation process is set up as follows:

[0174] Basic sensitivity S base =1.0;

[0175] Adjustment factor α = 0.005;

[0176] Adjustment factor β = 0.01;

[0177] If the current ambient humidity is 80% and the current temperature is 35°C, then:

[0178] S=1.0×(1-0.005×80-0.01×35)

[0179] S=1.0×(1-0.4-0.35)

[0180] S = 1.0 × 0.25 = 0.25

[0181] To avoid excessive reduction in sensitivity, the system sets a minimum sensitivity value S min ,for:

[0182] S=max(S,S min )

[0183] Among them, S min is the minimum acceptable value of sensitivity to prevent abnormal operation due to low sensitivity. The formula is:

[0184] S min =0.1

[0185] If the calculated S is less than S min , the sensitivity is limited to S min .

[0186] This solution automatically adjusts the touchscreen's sensitivity based on changes in humidity and temperature, preventing false touches or touch failures caused by changing environmental conditions and ensuring the system responds properly in all environments. It automatically reduces sensitivity in high-humidity or high-temperature environments to reduce the probability of misoperation, especially in industrial environments or during equipment operation, where temperature and humidity may fluctuate significantly. This solution effectively improves operational stability and reliability. By setting a minimum sensitivity value, it prevents sensitivity from being reduced to an unacceptable level, preventing normal operation from occurring and ensuring that the device always responds to valid touch input. The solution automatically adjusts touchscreen settings based on real-time environmental changes without manual intervention, enabling intelligent device management and saving the time and cost of manual adjustments. The solution adapts to a variety of environmental conditions, such as high humidity, high temperature, and low temperature, ensuring a good operating experience and reliability in all kinds of extreme environments. By ensuring touchscreen stability and responsiveness in various environments, users can enjoy a consistent and reliable experience when using the device, especially in unstable environments.

[0187] Before a critical operation, the system automatically triggers a multiple confirmation mechanism. The operator confirms the operation intention by pressing the pop-up option button on the touch screen and using voice recognition. For special or high-risk operations, the system pops up a warning message and asks the operator for a second confirmation. The method is as follows:

[0188] The system triggers a series of confirmation steps before key operations. The confirmation process for setting up an operation includes the following steps:

[0189] The operator performs preliminary confirmation by pressing the button on the touch screen. The validity of the touch screen confirmation is expressed by the following formula:

[0190] touch_confirm=f(button_press,T timeout )

[0191] touch_confirm is the result of touch screen confirmation, if valid, it is 1, if invalid, it is 0;

[0192] button_press is the pressing action of the touch screen button;

[0193] T timcout The timeout parameter for touch screen confirmation, that is, the time after the operator presses the button;

[0194] The voice recognition system confirms the operator's voice. If the operator's voice matches the preset confirmation command, the voice confirmation is valid. The formula is as follows:

[0195] voice_confirm=g(voice_input,command_list)

[0196] voice_confirm is the result of voice confirmation, which is 1 if valid and 0 if invalid;

[0197] voice_input is the operator's voice input;

[0198] command_list is the preset voice command list;

[0199] For special or high-risk operations, the system will pop up a warning message and require secondary confirmation. The formula is as follows:

[0200] risk_warning=h(operation_type,risk_threshold)

[0201] risk_warning is the pop-up result of the warning message, which is 1 if the warning is triggered and 0 if it is not triggered;

[0202] operation_type is the operation type;

[0203] risk_threshold is the risk threshold. When the operation type belongs to the high-risk category, a warning pops up;

[0204] After the system pops up a warning, the operator performs a second confirmation:

[0205] secondary_confirm=f(button_press,voice_input,T timcout )

[0206] secondary_confirm is the result of the secondary confirmation, which is 1 if valid and 0 if invalid;

[0207] T timcout is the timeout threshold for secondary confirmation;

[0208] The entire confirmation process is represented by the following comprehensive formula to ensure multiple verifications before key operations:

[0209]

[0210] Among them, operation_valid is the final confirmation result of whether the operation is valid, which is 1 if it is valid and 0 if it is invalid.

[0211] This solution uses multiple confirmation mechanisms (touch screen, voice recognition, warning messages, and secondary confirmation) to ensure that the operator's confirmation process is fully verified when performing critical operations. For high-risk operations, the system will pop up a warning and require secondary confirmation. This secondary confirmation mechanism effectively prevents operators from making incorrect operations without fully realizing the risks, thereby improving system safety. The touch screen's press confirmation and voice recognition confirmation mechanisms ensure that the operator's confirmation intention is multiply verified. Operators need to go through multiple confirmation processes before performing critical operations, allowing them to focus more when performing the operations and ensure that they can clearly understand and confirm the operation intentions at each step. This multiple confirmation mechanism not only improves system reliability, but also reminds operators to be cautious and avoid operational errors during high-risk operations. Through the combination of touch screen, voice, and secondary confirmation, the system avoids dependence on a single method. Even if a problem occurs in one method (such as voice recognition), other confirmation methods can still ensure the safety of the operation, thereby increasing the robustness of the system.

[0212] The system dynamically adjusts permissions based on the operator's identity and task requirements. If the operator is a low-privilege person, the system automatically limits their access to key control components and provides only the operating options within the scope of their permissions based on the task type. The method is as follows:

[0213] The authority level P of each operator is defined based on their identity. The range of authority levels is divided into several levels. The formula is:

[0214] P = f(operator_role)

[0215] operator_role represents the identity role of the operator;

[0216] P is the operator's permission level, and its value is defined as:

[0217] Low permissions: P low ;

[0218] Medium authority: P medium ;

[0219] High authority: P high ;

[0220] The system determines the scope of the operator's authority based on the current task type T. Each task type corresponds to a permission P. required :

[0221] P required =g(T)

[0222] P required Indicates the minimum permission level required for the current task;

[0223] T is the type of the current task;

[0224] When the operator performs a task, the system dynamically adjusts the scope of the operation according to the operator's authority level and the authority requirements of the task. If the operator's authority level P is lower than the authority required by the task P, the system will automatically adjust the scope of the operation according to the operator's authority level and the authority requirements of the task. required , the system will restrict its access rights to key control components, the formula is as follows:

[0225]

[0226] access_granted is a flag indicating whether the operator is allowed to perform the current task. If the operation is allowed, it is 1; if not, it is 0.

[0227] If the operator's authority is insufficient to perform the current task, the system will restrict the operation of key components and only provide operation options that are within the scope of their authority. The system generates an operation option list O based on the authority level P and task type T. allowed :

[0228] O allowed =h(P,T)

[0229] O allowed A set of operation options generated by the system for the operator;

[0230] h(P, T) is a function that generates operation options based on operator authority and task type;

[0231] For a low-privilege operator, if the task type is a high-risk operation and the operator's permission P low Lower than the required authority P for the task required , the system limits its access to key control components and provides options for granting operations to low-privilege operators;

[0232] The task is set to be a high-risk operation: T = high_risk_operation;

[0233] Operator authority: P low ;

[0234] Task authority requirements: P required =P high ;

[0235] At this time, P low <P required ,therefore:

[0236] access_granted=0

[0237] The system is implemented by formula O allowed =h(P low ,T high_risk_operation) Restrict operators to perform operations with low permissions;

[0238] For a high-authority operator, the task type is high-risk operation, and its authority P high Higher than the task required authority P required , the system authorizes the operator to perform the operation and provides complete operation options;

[0239] Set the task as a high-risk operation: T = high_risk_operation;

[0240] Operator authority: P high ;

[0241] Task authority requirements: P required =P high ;

[0242] At this time, P high ≥P required ,therefore:

[0243] access_granted=1

[0244] The system will be based on O allowed =h(P high ,T high_risk_operation ) Provide a complete set of high-risk operation options and authorize the operator to perform the operation;

[0245] In special cases, the system grants temporary enhanced permissions to low-privilege operators to complete tasks. Based on the operator's request and the approval of the superior, the system temporarily increases the permissions and generates a new permission level P temp :

[0246] P temp =P low +ΔP

[0247] ΔP represents the temporary increase in privileges;

[0248] The system is based on the new permission level P temp Reassess the scope of operator authority;

[0249] Before a task is executed, the system will determine whether the operation can be performed based on the operator's permissions and task requirements:

[0250]

[0251] The system dynamically adjusts permissions based on the operator's identity and task requirements, effectively avoiding the risks caused by excessive or insufficient permissions. The system automatically limits the access rights of low-privilege operators to key control components based on the task type, ensuring that only operators who meet the permission requirements can perform high-risk operations. By limiting the execution of high-risk tasks by low-privilege operators, the system avoids the risk of unauthorized personnel operating key control components. The system uses an automated permission control mechanism to help regulate the behavior of operators, ensuring that they can only operate within the scope of their permissions, reducing the possibility of misoperation and abuse of permissions. The solution is highly flexible and adaptable and can be adjusted according to different task types, operator identities and tasks. The system dynamically adjusts the authority level according to business needs, making it able to adapt to different work scenarios. By dynamically generating operation options that meet the authority range, operators do not need to manually search for executable task items. The system automatically filters out eligible operation options, reducing the operator's workload and improving efficiency. In special circumstances, low-authority operators can obtain temporary authority upgrades through approval from their superiors. This management and approval function increases the detailed management of authority control and improves the flexibility of task completion. By providing different operation options for operators at different authority levels, the system ensures that operators will not perform tasks beyond their authority range, thereby effectively reducing the risk of misoperation and ensuring system stability and security.

[0252] The substation control panel cabinet pressure plate anti-accidental touch system includes:

[0253] Infrared sensing modules are placed around the cabinet panel to detect the proximity and position of the operator's hand in real time. When the operator's hand approaches, the system enables or disables the touch area according to the preset operating conditions.

[0254] The gesture recognition module is used to identify the operator's hand posture and movements through cameras and image recognition technology, and trigger the corresponding operation instructions only when a valid gesture is detected;

[0255] Intelligent adjustment module, which is used to integrate environmental monitoring sensors to sense the humidity, temperature and light intensity of the environment and automatically adjust parameters such as touch screen sensitivity and button response time;

[0256] The voice recognition and feedback module is used to combine voice recognition technology to provide voice confirmation to the operator, ensuring that each operation of the operator is clearly confirmed. The operator initiates control instructions through voice commands, and the system uses voice feedback to ensure that the instructions have been received and executed;

[0257] The permission management module is used to integrate the authentication-based permission management system. All operators confirm their identities through fingerprint recognition, facial recognition or password verification. After identity confirmation, the system automatically sets different permissions according to roles and tasks.

[0258] By real-time detecting the proximity and position of the operator's hand, the system can effectively distinguish valid contact from actual contact, preventing accidental touches or other improper operations. Using cameras and image recognition technology, the module triggers the corresponding operation command only when a valid gesture is recognized. This prevents unintentional hand movements from causing misoperations, further enhancing the system's anti-misoperation capabilities. Combined with voice recognition technology, the operator can initiate control commands through voice commands, and the system confirms whether the command has been received and executed through voice feedback. Through the intelligent adjustment module, the system not only senses changes in environmental conditions but also dynamically adjusts the operating state of the equipment based on actual conditions, further enhancing the system's adaptability. Through voice recognition, gesture recognition, and infrared sensing, operators no longer need to use touchscreens or other traditional methods for operation. The system's voice feedback function not only confirms the receipt and execution of commands, but also provides real-time prompts or warnings when necessary, enhancing the operator's understanding of system status and helping them to promptly identify and resolve potential problems. The system's modular design allows for future optimization or expansion of individual modules as needed. With the development of artificial intelligence and the Internet of Things, the system can also integrate more intelligent analysis and prediction functions, such as equipment failure prediction and automatic optimization of environmental changes, further enhancing the automation and intelligence of substation operations.
