Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0061] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0062] Example 1, with reference to Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides a method for intelligent operation and remote monitoring of an electric door of a flameproof switch cabinet, comprising the following steps:

[0063] S1. Collect environmental data through the multimodal sensor on the electric door of the flameproof switchgear.

[0064] Monitor the temperature changes around the switch cabinet through the temperature sensor to obtain temperature data;

[0065] The temperature sensor uses a highly sensitive short-wave infrared sensor, which can accurately capture small changes in temperature in the surrounding environment;

[0066] Combined with a gas sensor (using a combustible gas detection sensor, such as the MQ series gas sensor) to detect changes in the concentration of combustible gas and obtain combustible gas data;

[0067] Preprocess temperature data and combustible gas data;

[0068] Specifically, high-frequency noise is removed by applying a low-pass filter to the infrared sensor signal;

[0069] By applying a sliding window to the raw data of the gas sensor for averaging, instantaneous abnormal fluctuations are removed;

[0070] The Max-Min method is used to normalize temperature data and combustible gas data and map them to the standard range of 0 to 1, making it easier to integrate the two types of sensor data;

[0071] The pre-processed temperature data is integrated with the combustible gas data to obtain a comprehensive environmental perception value;

[0072] The pre-processed temperature data and combustible gas data are fused by weighted averaging to obtain a comprehensive environmental perception value, which is expressed as:

[0073] ;

[0074] in, is the environmental perception value, is the temperature data weight coefficient, is the temperature data value after preprocessing, Indicates temperature, is the combustible gas data weight coefficient, is the combustible gas concentration value after pretreatment, Indicates flammable gas;

[0075] Based on the sensitivity and reliability of temperature sensors and gas sensors, calculate and ;

[0076] Specifically, sensitivity refers to the degree to which a sensor responds to environmental changes. The sensitivity evaluation formula for temperature sensors and gas sensors is:

[0077] , ;

[0078] in, and are the sensitivities of the temperature sensor and gas sensor, and They are the maximum and minimum values of the temperature change detected by the temperature sensor, and They are the maximum and minimum values of the combustible gas concentration change detected by the gas sensor;

[0079] The reliability of the sensor is expressed by the standard deviation, which is expressed as follows:

[0080] , ;

[0081] in, and are the reliability values of the temperature sensor and gas sensor respectively, and are the standard deviations of temperature data and combustible gas data, respectively;

[0082] Greater weight should be given to data detected by sensors with higher sensitivity and reliability. and The calculation expression is as follows:

[0083] , ;

[0084] By integrating real-time data from infrared sensors and gas sensors, the ambient temperature and combustible gas concentration can be comprehensively assessed, providing a basis for subsequent safety judgments and control operations.

[0085] S2. Evaluate the safety status of the environment based on the environmental data, and issue control instructions to the electric door of the flameproof switchgear according to the evaluation results.

[0086] Set the dangerous temperature threshold according to the safety instructions for the flameproof switchgear and internal equipment;

[0087] Generally speaking, the operating temperature range of flameproof switchgear should be between 30°C and 50°C. Exceeding this range will affect the service life and safety of the equipment.

[0088] Set the combustible gas dangerous concentration threshold according to the combustible gas type and lower explosion limit (LEL) concentration in the environment where the flameproof switchgear is located;

[0089] For lower hazard levels, 10%LEL is set as the combustible gas warning concentration threshold, and when the combustible gas concentration reaches 20%LEL, it is set as the combustible gas danger concentration threshold;

[0090] Normalize the dangerous temperature threshold and the dangerous flammable gas concentration threshold, and calculate the comprehensive safety threshold based on the environmental perception calculation formula. The expression is as follows:

[0091] ;

[0092] in, is the comprehensive safety threshold, is the normalized dangerous temperature threshold, is the combustible gas data weight coefficient, is the normalized combustible gas dangerous concentration threshold;

[0093] Evaluate the environmental safety status by comparing the environmental perception value and the comprehensive safety threshold;

[0094] ;

[0095] Based on the evaluation results, control instructions are issued to the electric doors of the flameproof switchgear;

[0096] When the evaluation result is When , it means the current environment status is safe and the operation continues according to the previous control instructions;

[0097] When the evaluation result is When the alarm is on, it indicates that there is a safety hazard in the current environment (high temperature or high concentration of combustible gas). The electric door of the explosion-proof switch cabinet is ordered to close and the maintenance unit is notified to conduct an inspection.

[0098] When the evaluation result is When the alarm is on, it indicates that the current environment is in a dangerous state, and the electric door of the flameproof switch cabinet is instructed to close at the maximum speed. At the same time, nearby personnel are notified to evacuate through broadcasting.

[0099] S3. Use quantum key distribution method to encrypt and transmit all control instructions.

[0100] Deploy a quantum key distribution (QKD) device between the electric door control terminal and the control center, including a quantum light source, quantum light detectors, and a fiber-optic communication network;

[0101] Transmission over fiber-optic networks using quantum bits (qubits), which are encoded based on the polarization states of photons (e.g., vertical and horizontal polarization);

[0102] Quantum key exchange protocols (such as the BB84 protocol) will be used to generate shared quantum keys, ensuring the uniqueness and anti-eavesdropping of the keys through quantum entanglement;

[0103] The control end of the electric door and the control center each generate a quantum key and exchange them through quantum bits in optical fiber communication;

[0104] After the quantum key exchange is successful, both parties will generate the same key. The key length is determined according to the security requirements of the system. Each encryption will use a new key to encrypt the data and exchange it through the quantum channel to ensure that both parties obtain the new key and stop using the old key.

[0105] The control end of the electric door encrypts the environmental assessment results and sends them to the control center. The control center decrypts them using the same quantum key and feeds back the newly encrypted control instructions.

[0106] The control end of the electric door decrypts and executes the encrypted control instructions using the same new quantum key;

[0107] After each decryption operation, the integrity of the control instruction is verified. For example, by checking whether the hash value of the control instruction before encryption is consistent with the hash value of the control instruction after decryption, it is confirmed that the data has not been tampered with during transmission. If inconsistency occurs during quantum key exchange or data decryption (such as data loss, decryption failure, etc.), a warning will be issued immediately, the operation will be stopped, and further investigation will be carried out.

[0108] S4. Based on digital twins, remote monitoring is carried out by building a virtual model of the explosion-proof switchgear electric door.

[0109] According to the structure, control unit and sensor deployment of the flameproof switch cabinet electric door, a simulation physical model of the flameproof switch cabinet electric door is constructed using MATLAB simulation software;

[0110] Specifically, the structural dimensions and operating status of the flameproof switch cabinet electric door simulation physical model are defined according to the structural dimensions and operating status of the flameproof switch cabinet electric door;

[0111] Define the operating parameters of the flameproof switchgear electric door simulation physical model according to the operating parameters of the flameproof switchgear electric door, such as door position, opening and closing speed, etc.

[0112] Based on the control instructions of the control center for the electric door of the flameproof switch cabinet, the opening and closing actions of the electric door are mapped to the simulation physical model, so that the simulation physical model dynamically displays the operation of the electric door, and a virtual model of the electric door of the flameproof switch cabinet is obtained;

[0113] Specifically, the control algorithm converts the switch command into an action input of the simulated physical model. For example, the "open door" command specifies a target position (such as the maximum position of the fully opened door), and the motion path and speed from the current state to the target position are calculated through the dynamic equations of the simulated physical model.

[0114] Based on the real-time collected temperature and combustible gas data, the system evaluates the environmental safety status and issues control instructions to the electric door of the explosion-proof switchgear in real time based on the evaluation results.

[0115] The real-time control instructions for the flameproof switchgear electric door are mapped to the virtual model, allowing operators to remotely monitor the opening and closing status of the flameproof switchgear electric door in real time.

[0116] When the command is executed, the virtual model will immediately feedback the state changes of the electric door (such as position changes, speed changes, etc.), and the operator can confirm whether the control command is successfully executed through the feedback information.
