Description

Technical Field

[0001] The present invention relates to the technical field of power cabinets, and in particular to an intelligent door opening system for a power cabinet and a power cabinet. Background Art

[0002] As a core component of the power system, the safety of the power cabinet plays a vital role in ensuring the stable operation of the power grid and protecting personal safety. In order to effectively manage the access rights of the power cabinet and prevent unauthorized personnel from operating, the power industry has adopted a variety of access control technologies, but each technology has its limitations and potential security risks. For example, mechanical locks are the most common access control method. The power cabinet is opened by a physical key. Although it is simple and easy to use, the key is easy to lose or steal. Once it falls into the hands of criminals, it will pose a serious threat to power facilities. In addition, mechanical locks cannot record the time of unlocking and the information of the operator, which brings great difficulties to subsequent tracking and responsibility definition. A specific case is that during an emergency maintenance of a power company, the maintenance personnel forgot to bring the key and were unable to open the power cabinet in time, resulting in maintenance delays, which eventually caused a larger-scale power outage.

[0003] Electronic password locks provide a certain degree of security improvement. Users need to enter a pre-set password to unlock the lock. However, the password may be guessed or leaked by others, or even cracked by brute force. Therefore, in scenarios with high security requirements, the protection capabilities of electronic password locks are insufficient. Biometric technologies, such as fingerprint recognition and facial recognition, have greatly improved the security of the system because everyone's biometrics are unique, but biometrics also face challenges. On the one hand, biometric data may be illegally copied; on the other hand, in specific working environments (such as when workers wear gloves or have hand injuries), biometrics may not work properly, thus affecting work efficiency. For example, during the maintenance of a power cabinet, unauthorized personnel entered the power cabinet by copying fingerprints, causing damage to the equipment and causing serious economic losses.

[0004] In summary, the security of the power cabinet access control system is extremely important. It is not only related to the normal operation of the power system, but also an important line of defense to protect the lives of workers. In the face of many shortcomings of traditional access control methods, the power industry should actively explore more advanced and reliable solutions to cope with increasingly complex security challenges and ensure the safety and stability of the power system.

[0032] Example 1: Please refer to Figure 1-Figure 5 The power cabinet of this embodiment includes a cabinet body 100 and a cabinet door 200. The cabinet door 200 is hinged to the cabinet body 100 through a hinge shaft, the hinge shaft is horizontally arranged, the upper end of the cabinet door 200 is hinged to the cabinet body 100 through the hinge shaft, and the lower end of the cabinet door 200 is provided with a door handle 201. The hinge shaft is detachably connected to a motor 300, so that the cabinet door 200 can be opened and closed by controlling the motor 300, and after the motor 300 is removed, the cabinet door 200 can be opened and closed by the door handle 201.

[0033] The end of the articulated shaft is connected to an articulated shaft wheel 400, and the end of the motor 300 is connected to a motor wheel 301. The articulated shaft wheel 400 and the motor wheel 301 are connected through a transmission belt 500 and a belt-pressing roller 501. The belt-pressing roller 501 acts on the transmission belt 500 to enable the articulated shaft wheel 400 and the motor wheel 301 to be connected through the transmission belt 500. If the belt-pressing roller 501 does not act on the transmission belt 500, the articulated shaft wheel 400 and the motor wheel 301 cannot be connected through the transmission belt 500, and it is convenient to remove the motor 300 and the motor wheel 301. In practice, if the position space of the articulated shaft is limited, a pair of gear sets can be used for intermediate transmission and finally connected to the articulated shaft wheel 400.

[0034] In order to facilitate the removal of the motor 300 and the motor wheel 301, the pinch roller 501 is connected with a clamping mechanism. When the clamping mechanism is in a clamping state, the pinch roller 501 abuts against the transmission belt 500 and causes the articulated shaft wheel 400 and the motor wheel 301 to be connected by the transmission belt 500. At this time, the motor wheel 301 is bound by the transmission belt 500 and is not easy to remove the motor 300 and the motor wheel 301. When the clamping mechanism is in a non-clamping state, the pinch roller 501 is separated from the transmission belt 500 and causes the articulated shaft wheel 400 and the motor wheel 301 to be unable to be connected by the transmission belt 500. At this time, the motor wheel 301 is no longer bound by the transmission belt 500 and is easy to remove the motor 300 and the motor wheel 301. A motor box 101 is provided on the top of the cabinet body 100, and an emergency panel 102 is connected to the front side of the motor box 101. The emergency panel 102 covers the motor 300 in the motor box 101, and the motor 300 is specifically clamped in the motor box 101. When the clamping mechanism is in a non-clamping state, the motor wheel 301 is no longer constrained by the transmission belt 500. At this time, after opening the emergency panel 102, it is convenient to remove the motor 300 from the motor box 101, and then the hinge shaft and the hinge shaft wheel 400 are no longer constrained by the motor wheel 301 and the motor 300, so that the operator can manually operate the cabinet door 200 through the door handle 201 at the lower end of the cabinet door 200.

[0035] The clamping mechanism includes a first clamping rod 601, a second clamping rod 602 and a pressure rod 603. The second clamping rod 602 and the first clamping rod 601 can be detachably hooked together. The pressure rod 603 is hinged to the first clamping rod 601 or the second clamping rod 602, and can lock the hooked second clamping rod 602 and the first clamping rod 601. The belt-push roller 501 is connected to the belt-push roller plate 502 and is connected to the clamping mechanism through the belt-push roller plate 502. One end of the belt-push roller plate 502 is hinged to the cabinet 100, and the other end is hinged to the first clamping rod 601. The second clamping rod 602 is hinged to the cabinet 100 and is opposite to the position of the first clamping rod 601, that is, the second clamping rod 602 and the first clamping rod 601 are arranged on both sides of the motor 300. In this way, after the second clamping rod 602 and the first clamping rod 601 are hooked with each other and in place, the positions of the two are locked by the pressure rod 603. At the same time, the two drive the belt-push roller plate 502 to drive the belt-push roller 501 to abut against the transmission belt 500 and promote the transmission connection between the articulated shaft wheel 400 and the motor wheel 301 through the transmission belt 500, that is, the clamping mechanism is in a clamping state. On the contrary, when the pressure rod 603 is unlocked and the second clamping rod 602 is separated from the first clamping rod 601, the first clamping rod 601 will drive the belt pressure roller plate 502 to drive the belt pressure roller 501 to disengage from the abutment with the transmission belt 500 and make it impossible for the articulated shaft wheel 400 and the motor wheel 301 to be connected through the transmission belt 500, that is, the clamping mechanism is in a non-clamping state.

[0036] The intelligent door opening system of the power cabinet includes a data receiving unit, a data decryption unit, a verification unit and an execution unit. The data receiving unit is used to receive communication data encrypted based on gesture recognition results, wherein the key used for encrypted communication is generated by a quantum key distribution system based on the principle of quantum mechanics. The data decryption unit is used to decrypt the communication data to generate gesture recognition results, wherein the key used for decrypted communication is the same key as the encryption key generated by the quantum key distribution system based on the principle of quantum mechanics, and the quantum key distribution system uses the BB84 protocol to generate quantum keys, and after verifying the integrity of the key through quantum state measurement, the verified key is distributed to the gesture recognition sensor and the power cabinet control center, so that the gesture recognition sensor uses the quantum key to encrypt the gesture recognition result to form encrypted communication data, and the power cabinet control center uses the quantum key to decrypt the encrypted communication data to form the gesture recognition result. The verification unit is used to verify whether the decrypted gesture recognition result is an authorized gesture. The execution unit is used to control the motor to drive the power cabinet door to open after the verification is passed, and trigger the emergency manual mode when the motor fails or the power supply has problems, prompting the operator to manually open the cabinet door after further verification is successful.

[0037] The operating principle of the intelligent door opening system of the power cabinet is introduced in detail below.

[0038] 1. Accept the operator's gestures: The gesture recognition sensor installed on the power cabinet captures the operator's gestures and converts them into digital signals. Specifically, the gesture recognition sensor is activated, the sensor captures the operator's gestures, generates a gesture data stream, and transmits the gesture data stream to the gesture recognition module.

[0039] 2. Gesture recognition: A gesture recognition algorithm based on deep learning recognizes preset authorized gestures through training models. Specifically, ① Data preprocessing: Normalize the collected gesture data to remove noise. Generally, the mean value of the data, the standard deviation of the data, etc. are used for normalization to eliminate the differences between the data and improve the robustness of the model. ② Feature extraction: Use convolutional neural network (CNN) to extract the feature vector of the gesture. CNN extracts key features from the gesture image through multi-layer convolution and pooling operations. ③ Classifier: Use support vector machine (SVM) or other classifiers to classify the feature vector to determine whether it is an authorized gesture. SVM separates gesture data of different categories by finding the optimal hyperplane to achieve classification. ④ Threshold judgment: Set the threshold. If the classification probability is greater than the threshold, the gesture recognition is considered successful. The threshold is adjusted according to the actual application scenario and security requirements to ensure the accuracy and security of the system.

[0040] 3. Quantum key distribution: The quantum key distribution system generates and distributes keys for encrypted communications based on the principles of quantum mechanics. Specifically, ① Key generation: The quantum key K is generated using the BB84 protocol. The BB84 protocol ensures that the key generation process is secure by sending quantum state photons, and any eavesdropping will be detected. ② Key verification: The integrity of the key is verified through quantum state measurement. Key verification ensures that the key has not been tampered with by comparing the measurement results of the receiver and the sender. ③ Key distribution: The verified key K is distributed to the gesture recognition sensor and the power cabinet control center to ensure that the key is securely distributed to each component for subsequent encryption and decryption operations.

[0041] 4. Secure communication protocol: Use quantum keys to encrypt gesture recognition results to ensure that data is not stolen during transmission. Specifically, ① Data encryption: Use the AES algorithm to encrypt gesture recognition results, that is, encrypt gesture recognition results and quantum key K. AES is a symmetric encryption algorithm that ensures data confidentiality and integrity. ② Data transmission: Send the encrypted data to the power cabinet control center.

[0042] 5. Intelligent door opening mechanism: After receiving the encrypted data, the power cabinet control center uses the same key to decrypt and verify the gesture recognition result. If the verification is successful, the power cabinet door is automatically unlocked and opened. Specifically, ① Data reception: The control center receives the encrypted communication data. ② Data decryption: Use the same key K to decrypt the data and restore the gesture recognition result. ③ Verification result: Check whether the gesture recognition result after decryption is an authorized gesture to ensure the legitimacy of the operator. ④ Normal door opening: The control center sends a command to the motor, which drives and opens the door of the power cabinet. ⑤ Emergency manual door opening: The control center detects the motor status. If the motor fails or the power supply has problems, the emergency manual mode is triggered, and the operator is prompted to enter the emergency manual mode through the display screen or voice. Identity verification is performed during the process. For example, the operator uses the authorized key to open the emergency panel 102, unlocks it through the pressure rod 603, and separates the second clamping rod 602 from the first clamping rod 601. The first clamping rod 601 will drive the belt pressure roller plate 502 to drive the belt pressure roller 501 out of contact with the transmission belt 500 and prevent the articulated shaft wheel 400 and the motor wheel 301 from being connected through the transmission belt 500, so that the motor 300 can be removed from the motor box 101. Then, the articulated shaft and the articulated shaft wheel 400 are no longer constrained by the motor wheel 301 and the motor 300, so that the operator can manually operate the cabinet door 200 through the door handle 201 at the lower end of the cabinet door 200. Of course, biometric verification can also be used. The operator puts his finger on the fingerprint identifier and the system verifies the fingerprint information. A one-time verification code may also be used, where the system generates a one-time verification code and sends it to the operator via a mobile phone or a dedicated device, and the operator inputs the verification code to complete the verification. Of course, the emergency panel 102 may be automatically opened after the verification is passed.

[0043] 6. Security feedback mechanism: The system records the results of each operation, and adjusts the parameters of the gesture recognition algorithm and the quantum key distribution strategy according to the success or failure of the operation to improve the accuracy and security of the system. Specifically, ① Log recording: After each operation is completed, the system records the operation log, including information such as operation time, operator, and operation results. ② Data analysis: Regularly analyze the operation log and count the number of successful and failed operations. ③ Parameter adjustment: According to the analysis results, adjust the parameters of the gesture recognition algorithm and the quantum key distribution strategy, such as through the gradient descent method, continuously optimize the gesture recognition model and improve the recognition accuracy. These are conventional technical means and will not be repeated here. ④ Strategy update: According to the operation results, adjust the frequency and key length of quantum key distribution to improve the security of the system.

[0044] Embodiment 2: Based on the embodiment 1, the belt-pressing roller plate 502 of this embodiment is provided with an adjusting member 503, which is a screw structure and can finely adjust the position of the belt-pressing roller 502. Specifically, the belt-pressing roller 502 is rotatably connected to a wheel frame, and the wheel frame is slidably connected to the belt-pressing roller plate 502 and is adjusted and locked by the adjusting member 503, so that the position of the belt-pressing roller 501 can be easily adjusted so that after the belt-pressing roller 501 acts on the transmission belt 500, the articulated shaft wheel 400 and the motor wheel 301 can be connected through the transmission belt 500. The other structures of this embodiment are consistent with those of the embodiment 1 and will not be described in detail here.
