[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0027] Example 1, reference Figure 1 , as an embodiment of the present invention, provides an electrical control cabinet door abnormal opening alarm monitoring method, comprising:

[0028] S1: Collect first status information of the first object.

[0029] The first state information includes a signal sent by a sub-part of the first object in a current real-time state.

[0030] In this embodiment, the first object is an electrical control cabinet, its sub-part refers to the cabinet door, and the real-time state refers to the switch state of the cabinet door. The first state information is a physical or electronic signal generated and collected by the cabinet door of the electrical control cabinet (i.e., the sub-part of the first object) in its real-time state, which is used to reflect the switch state of the cabinet door. Specifically, the signal can be one or more of the following forms:

[0031] 1. Mechanical switch signal

[0032] Use a mechanical switch (such as a limit switch or travel switch) installed on the cabinet door to detect the open or closed state of the cabinet door.

[0033] When the cabinet door is in a closed or open state, the switch will generate a corresponding signal output (such as a high level or a low level).

[0034] 2. Magnetic induction signal

[0035] The door position is detected by a magnetic sensor (such as a Hall sensor) and a magnet assembly.

[0036] When the cabinet door is opened or closed, the sensor detects the change in magnetic field and outputs a corresponding signal.

[0037] 3. Optical signal

[0038] Use photoelectric sensors to detect the state of the cabinet door by emitting and receiving changes in light.

[0039] If the door blocks or removes the light beam, the sensor outputs a different signal.

[0040] 4. Wireless signal

[0041] The door is detected by a radio frequency tag (RFID) or a Bluetooth module.

[0042] A signal is generated corresponding to a change in tag state (such as a change in distance or position).

[0043] 5. Circuit status signal

[0044] The opening and closing of the cabinet door may change the circuit connection state (such as short circuit or disconnection), and a signal is generated by monitoring the circuit state change.

[0045] In this embodiment, the signal of the first status information is finally transmitted to the acquisition unit in the form of voltage, current, pulse or digital code, for further analysis and judgment of whether the real-time status of the cabinet door meets the standard status.

[0046] In an optional embodiment, if a vehicle is used as the first object and a sub-part is selected as the design object, such as a vehicle door, the first state information may also be a door switch state signal. Signal description: Whether the door is open or closed is detected by the installed limit switch or magnetic induction sensor. The signal output is a digital signal (for example: 1 indicates that the door is open, and 0 indicates that the door is closed).

[0047] S2: Parse the first status information and acquire first standard information of the first object.

[0048] The analysis includes converting the signal of the first state information to obtain the real-time state of the first object sub-part, including but not limited to open and closed states.

[0049] Furthermore, the first standard information includes current standard status information of each sub-part of the first object. The standard status includes but is not limited to the authority control of the central control unit on the status of each sub-part. If the authority is passed, it is a standard status.

[0050] In this embodiment, the first standard information is the permission status of the current cabinet door switch. The permission status determines whether the operation is allowed. The cabinet door is only allowed to be opened by authorized users or under specific conditions. For example: After the maintenance personnel swipes a card, enters a password or biometric authentication (such as fingerprint, facial recognition), the cabinet door is authorized to open. In the running state, the cabinet door operation is limited to the locked state.

[0051] In an optional embodiment, the first standard information can be extended to multiple reference states under vehicle operation scenarios, rather than being limited to authority control. The first standard information is presented in the form of a feasible domain range, covering a reasonable range of door states. The first standard information defines the standard state of the door, and the feasible domain range can be set according to different operation scenarios and functional requirements of the door. For example: Description of the feasible domain of the in-vehicle state: The standard state of the door is determined based on other in-vehicle states (such as seat belts, number of passengers, etc.).

[0052] Feasible domain range:

[0053] Seat belt status:

[0054] When the seat belt is not fastened, the door is closed but not locked, reminding the user to fasten the seat belt.

[0055] After the seat belt is fastened, the door will automatically lock (while driving).

[0056] Seat occupancy sensor:

[0057] If the seat is occupied but the door is open, it may indicate that the door is not closed properly.

[0058] S3: Compare the parsed first status information with the first standard information to generate an alarm control instruction.

[0059] The control instructions include issuing an alarm suppression instruction if the verification results are consistent; and issuing an alarm execution instruction if the verification results are inconsistent.

[0060] Specifically, the permission information of the current user or system for operating the cabinet door is obtained from the central control unit.

[0061] Parse real-time status information and convert sensor signals into readable status: Is the door completely closed? Is unauthorized operation detected? Does the lock status meet the requirements (such as locked or unlocked). For example, obtain the standard status that meets the current operating conditions from the system standard information library. Standard = {door open: 0, locked: 1}, that is, the door must be closed and locked.

[0062] The parsed real-time status information is compared with the standard information item by item, and the following logical judgments are performed:

[0063] Exactly the same:

[0064] The real-time status fully complies with the standard status, is recognized as a normal status, and an alarm suppression instruction is issued.

[0065] example:

[0066] Real-time status: {Door open: 0, locked: 1}

[0067] Standard status: {door open: 0, locked: 1}

[0068] Verification result: consistent, suppress alarm.

[0069] There are inconsistencies:

[0070] If there is a deviation between the real-time status and the standard status, it is identified as an abnormal state and an alarm execution instruction is issued.

[0071] example:

[0072] Real-time status: {Door open: 1, locked: 0}

[0073] Standard status: {door open: 0, locked: 1}

[0074] Verification result: inconsistent, alarm executed.

[0075] S4: After obtaining the control instruction, analyzing the first control element of the first object, and re-correcting the control instruction according to the analysis result.

[0076] The first control factor includes a key condition for performing an analysis of whether the state of each sub-part of the first object is abnormal.

[0077] In this embodiment, the key condition refers to whether an abnormality occurs in each working unit inside the electrical cabinet. If an abnormality occurs, it is reasonable to open it, and the original instruction is corrected at this time.

[0078] The first control factor is the operating status of each working unit inside the electrical cabinet (such as circuit breakers, relays, transformers, control modules, etc.), whether a fault or abnormality occurs (such as overload, overtemperature, short circuit, etc.).

[0079] If the working unit is normal: the opening of the cabinet door is usually unreasonable and the alarm execution instruction should be maintained.

[0080] If the working unit is abnormal: the opening of the cabinet door may be reasonable (such as maintenance needs), and it should be re-corrected to an alarm suppression instruction.

[0081] Among them, abnormal judgment conditions:

[0082] An internal unit failure is detected (such as overtemperature, short circuit, abnormal voltage, etc.).

[0083] It is detected that some internal components are in non-standard working conditions (such as circuit breaker tripping, equipment power failure, etc.).

[0084] S5: Using the re-corrected control instructions, the alarm system is controlled.

[0085] Embodiment 2 is an embodiment of the present invention. This embodiment also provides an abnormal opening alarm monitoring system for an electrical control cabinet door, which is characterized by:

[0086] The collecting unit collects the first state information of the first object; analyzes the first state information, and acquires the first standard information of the first object.

[0087] The analyzing unit compares the parsed first status information with the first standard information and generates an alarm control instruction.

[0088] The correction unit analyzes the first control element of the first object after receiving the control instruction, and re-corrects the control instruction according to the analysis result.

[0089] The execution unit controls the alarm system using the re-corrected control instructions.

[0090] If the above functions are implemented in the form of software functional units and sold or used as independent products, they can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, or the part that contributes to the prior art or the part of the technical solution, can be embodied in the form of a software product. The computer software product is stored in a storage medium, including several instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to perform all or part of the steps of the method described in each embodiment of the present invention.

For the purposes of this specification, "computer-readable medium" can be any device that can contain, store, communicate, propagate or transmit a program for use by an instruction execution system, device or apparatus, or in conjunction with such instruction execution systems, devices or apparatuses.

In addition, the computer-readable medium may even be a paper or other suitable medium on which the program is printed, since the program may be obtained electronically, for example, by optically scanning the paper or other medium, followed by editing, deciphering or, if necessary, processing in another suitable manner, and then stored in a computer memory.

[0094] Example 3 is an embodiment of the present invention, which provides an abnormal opening alarm monitoring method for an electrical control cabinet door. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0095] The experimental platform includes: a standard industrial electrical control cabinet, equipped with switch sensors, magnetic induction sensors and lock status sensors, and contains common electrical components such as circuit breakers, relays and transformers. The test platform is connected to the monitoring system through a central control unit to collect the status signals of the cabinet door and the operating status of the internal equipment in real time.

[0096] The experimental setup is as follows:

[0097] Experimental object: Test the performance of the alarm monitoring system of the electrical cabinet door, including the monitoring capability of the cabinet door status, the internal working unit status and the alarm accuracy.

[0098] Test scenario: put the cabinet door into three states:

[0099] Normally closed and locked.

[0100] Unauthorized opening.

[0101] Opens when an internal device failure occurs.

[0102] Experimental parameters:

[0103] Real-time status signal: whether the cabinet door is closed or locked.

[0104] Permission status: whether the cabinet door is allowed to be opened.

[0105] Internal device status: whether a fault has occurred (such as circuit breaker tripping, transformer overheating).

[0106] Experimental steps:

[0107] Signal collection and analysis: The real-time status information of the cabinet door is collected through the switch sensor and magnetic induction sensor, and converted into digital signals; the permission status is recorded through the permission verification module to ensure the accuracy of real-time data.

[0108] Standard information setting: Set the standard status for different scenarios, for example: the cabinet door must be closed and locked in the running state, and the cabinet door is allowed to be opened when the internal equipment fails.

[0109] Verification and control instruction generation: Verify the collected real-time status with the standard status. If they are consistent, suppress the alarm. If they are inconsistent, issue an alarm execution instruction.

[0110] Internal unit status analysis: simulate internal equipment failure (such as transformer overheating to 90°C) to analyze whether the failure affects the alarm decision; re-correct the alarm instruction under abnormal circumstances.

[0111] Result recording: Record the cabinet door status, authority status, internal equipment status and alarm system response in each experiment.

[0113]

[0114]

[0115] The above experimental data show that the proposed electrical control cabinet door abnormal opening alarm monitoring method has significant advantages in accuracy, response speed and false alarm rate. The following is a specific analysis:

[0116] Experiments 1 and 2 verified the system's alarm capabilities in authorized and unauthorized states. When the cabinet door is normally closed and locked, the system can successfully suppress the alarm without false alarms; when the cabinet door is opened without authorization, the system quickly executes the alarm, and the response time is kept within 55ms, which is significantly better than traditional mechanical alarms (usually delayed by about 200ms).

[0117] Experiments 3 and 5 simulated scenarios when an abnormality occurred in an internal unit. The system corrected the original alarm instruction through the first control factor analysis, making the alarm suppression successful. This dynamic adjustment mechanism is not involved in the prior art and solves the problem of false alarms caused by internal faults.

[0118] Evaluation of system performance:

[0119] Experimental data show that the average response time of the system is 52.5ms, significantly better than traditional technologies (usually above 100ms).

[0120] In 6 experiments, the false alarm rate remained at 0%, indicating that the system has high accuracy in processing permission status and equipment failure analysis. The false alarm rate of traditional systems in complex scenarios is about 10%-15%.

[0121] This method implements dynamic correction alarm logic by analyzing real-time status and standard information and combining it with the first control factor (such as internal equipment failure status), ensuring the rationality of the alarm decision.

[0122] It provides multi-dimensional data support, such as real-time status, permission status and device status, making the system more intelligent and able to adapt to the needs of different application scenarios.

[0123] The data shows that the system can accurately handle alarm decisions in complex scenarios such as unauthorized opening and equipment failure, while existing technologies often fail to provide a dynamic adjustment mechanism when permissions conflict with device status.

[0124] Through experimental data and comparative analysis, it can be concluded that the alarm monitoring method of the present invention has significant advantages in accuracy, intelligence and response speed, especially its adaptability in complex industrial environments far exceeds that of existing technologies.

[0125] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
