[0004] The above technology has the following problems: the above remote-controlled electrical control cabinet system has preset control logic operations, user interface operations and remote server operations at the same time, but does not verify the operating identities of the three and does not perform conflict detection on the operating information. It is impossible for the control personnel to master all the operating precautions of the electrical control cabinet at the same time, and it is easy to make wrong operations that cause the electrical control cabinet to malfunction.

[0005] In view of this, a remote-controlled electrical control cabinet system is designed to solve the above problems. Summary of the Invention

[0006] In order to solve the problems raised in the above background technology, the present invention provides a remote control electrical control cabinet system, which has the characteristics of effectively avoiding the occurrence of erroneous operation of the electrical control cabinet and ensuring the control accuracy of the electrical control cabinet.

[0007] To achieve the above object, the present invention provides the following technical solution: a remotely controlled electrical control cabinet system, comprising:

[0008] The logic control module stores the control logic flow of the electrical control cabinet and controls the operation of the electrical control cabinet based on the stored control logic flow without external interaction. The operation includes operation execution.

[0009] The interface control module controls the operation of the electrical control cabinet based on the human-machine interface interaction, and the operation includes operation execution;

[0010] Remote control module, which controls the operation of the electrical control cabinet based on remote server communication interaction, including operation execution;

[0011] The control switching rationality judgment module receives the human-machine interface control signal or remote control signal, and judges the conflict between the control signal and the current electrical control cabinet operation control logic based on the constructed control switching rationality judgment model. If there is no conflict, the human-machine interface control signal or remote control signal is judged to be reasonable, otherwise it is judged to be unreasonable;

[0012] The control switching module switches to respond to the human-machine interface control signal or remote control signal if the control switching judgment is reasonable, otherwise it does not switch and continues to respond to the logic control signal;

[0013] Electrical control cabinet module, the electrical control cabinet responds to logic control signals, human-machine interface control signals or remote control signals to operate, and the operation includes operation execution.

[0014] Furthermore, the interface control module includes:

[0015] A first control personnel identity information storage module, which inputs and saves the identity information of the controllable personnel based on the human-machine interface;

[0016] The first control personnel identity authentication module, before operating the human-machine interface to interactively control the electrical control cabinet, the human-machine interface pops up identity authentication information, the control personnel enters the identity information, the human-machine interface performs verification, if the verification fails, the pop-up "Authentication Failed" appears, if the verification succeeds, the pop-up "Authentication Successful" appears;

[0017] Human-machine interface interaction module, after successful authentication of the control personnel, inputs control instructions based on the human-machine interface, and performs control based on the control instructions.

[0018] Furthermore, the remote control module includes:

[0019] The second control personnel identity information storage module is configured to input and save the identity information of the controllable personnel based on the remote server page;

[0020] The second control personnel identity authentication module operates the remote server page to interactively control the electrical control cabinet. The remote server page pops up identity authentication information. The control personnel enters the identity information and the remote server performs verification. If the verification fails, the pop-up "Authentication Failed" appears. If the verification succeeds, the pop-up "Authentication Successful" appears.

[0021] In the remote server interaction module, the control personnel successfully authenticates and inputs control instructions based on the remote server page, and performs control based on the control instructions.

[0022] Furthermore, in the control switching rationality judgment module, the specific steps of judging the conflict between the control switching rationality judgment model and the current electrical control cabinet operation control logic include:

[0023] Obtain historical operating data of electrical control cabinets, including operation execution data;

[0024] Acquire operation execution instruction input data and operation execution result data from the operation execution data;

[0025] obtaining conflicting operation execution instruction input data based on the operation execution result data;

[0026] Taking the conflicting operation execution instruction input data as the independent variable and the corresponding operation execution result data as the dependent variable, a control switching rationality judgment model is constructed, and the expression is:

[0027] Y=a0+a1X1+a2X2+ε

[0028] Where: Y is the result of the operation execution, a0, a1 and a2 are the conflict coefficients, X1 and X2 are the two operation execution instruction inputs, and ε is the error term;

[0029] The operation execution result is predicted based on the human-machine interface control signal or the remote control signal and the logic control signal. If the operation execution result is correct, the signal is reasonable, otherwise it is unreasonable.

[0030] Furthermore, the logic control module controls the operation of the electrical control cabinet and also includes status monitoring. When a fault is detected in the operating status of the electrical control cabinet, the operation control related to the fault in the logic control process is suspended, and the human-machine interface and the remote server are notified at the same time for timely maintenance. The human-machine interface control signals or remote control signals involved in the maintenance process are saved in the logic control process. When the same fault occurs subsequently, the same human-machine interface control signals or remote control signals sent by the human-machine interface and the remote server are exempted from rationality judgment, and the electrical control cabinet responds directly.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The present invention judges the rationality of logic control, interface control and remote control instructions and sets priorities. When there is no external interaction, logic control is optimal. When there is external interaction, the rationality between interface control and remote control and current logic control is judged. If reasonable, the interface control and remote control are responded to. If unreasonable, the logic control is responded to. This can effectively avoid the occurrence of erroneous operations of the electrical control cabinet and ensure the control accuracy of the electrical control cabinet. At the same time, the rationality is judged based on the operation execution results predicted by the model, with high accuracy.

[0033] 2. After a fault occurs in the electrical control cabinet of the present invention, the maintenance logic is saved in the logic control path. If the same situation occurs later, if the corresponding interface control and remote control signals exist in the saved maintenance logic, the rationality judgment is eliminated when sending the same interface control and remote control signals, thereby improving the response speed of the electrical control cabinet during maintenance and improving the maintenance efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] Interface control module 2, which controls the operation of the electrical control cabinet based on human-machine interface interaction, including operation execution;

[0046] The control process of human-computer interface interaction is input instructions, which are understood and controlled by the built-in processor;

[0047] Remote control module 3, which controls the operation of the electrical control cabinet based on remote server communication interaction, including operation execution;

[0048] The remote control process of the remote server is to input instructions through the server page. The input instructions are input through the communication protocol between the electrical control cabinet and the remote server, and the input instructions are understood and controlled by the built-in processor;

[0049] The control switching rationality judgment module 4 receives the human-machine interface control signal or the remote control signal, and judges the conflict between the human-machine interface control signal or the remote control signal and the current electrical control cabinet operation control logic based on the constructed control switching rationality judgment model. If there is no conflict, the human-machine interface control signal or the remote control signal is judged to be reasonable, otherwise it is judged to be unreasonable;

[0050] Control switching module 5, if the control switching judgment is reasonable, it switches to respond to the human-machine interface control signal or the remote control signal, otherwise it does not switch and continues to respond to the logic control signal;

[0051] The electrical control cabinet module 6 operates in response to logic control signals, human-machine interface control signals or remote control signals, and the operation includes operation execution.

[0052] Specifically, the interface control module 2 includes:

[0053] The first control personnel identity information storage module 201 is configured to input and save the identity information of the control personnel based on the human-machine interface;

[0054] It is convenient for subsequent identity information comparison and verification to prevent irrelevant personnel from operating the human-machine interface and inputting wrong instructions, as well as control personnel from accidentally touching the human-machine interface and inputting wrong instructions;

[0055] The first control personnel identity authentication module 202, before operating the human-machine interface to interactively control the electrical control cabinet, the human-machine interface pops up identity authentication information, the control personnel enters the identity information, the human-machine interface performs verification, if the verification fails, the pop-up "Authentication Failed" appears, if the verification succeeds, the pop-up "Authentication Successful" appears;

[0056] Identity authentication to prevent irrelevant personnel from operating the human-machine interface and inputting erroneous instructions, as well as control personnel from accidentally touching the human-machine interface and inputting erroneous instructions;

[0057] The human-machine interface interaction module 203 controls the personnel to successfully pass identity authentication, input control instructions based on the human-machine interface, and perform control based on the control instructions.

[0058] Specifically, the remote control module 3 includes:

[0059] The second control personnel identity information storage module 301 is configured to input and save the identity information of the controllable personnel based on the remote server page;

[0060] Facilitates subsequent identity information comparison and verification to prevent unrelated personnel from entering erroneous instructions through the remote server;

[0061] The second control personnel identity authentication module 302 operates the remote server page to interactively control the electrical control cabinet. The remote server page pops up identity authentication information. The control personnel enters the identity information and the remote server performs verification. If the verification fails, the pop-up message "Authentication failed" appears. If the verification succeeds, the pop-up message "Authentication successful" appears.

[0062] Identity authentication to prevent irrelevant personnel from entering erroneous instructions through the remote server;

[0063] In the remote server interaction module 303 , the control personnel successfully passes the identity authentication, inputs the control instruction based on the remote server page, and performs control based on the control instruction.

[0064] Specifically, in the control switching rationality judgment module 4, the specific steps of judging the conflict between the control switching rationality judgment model and the current electrical control cabinet operation control logic include:

[0065] Obtain historical operating data of electrical control cabinets, including operation execution data;

[0066] Acquire operation execution instruction input data and operation execution result data from the operation execution data;

[0067] obtaining conflicting operation execution instruction input data based on the operation execution result data;

[0068] Taking the conflicting operation execution instruction input data as the independent variable and the corresponding operation execution result data as the dependent variable, a control switching rationality judgment model is constructed, and the expression is:

[0069] Y=a0+a1X1+a2X2+ε

[0070] Where: Y is the result of the operation execution, a0, a1 and a2 are the conflict coefficients, X1 and X2 are the two operation execution instruction inputs, and ε is the error term;

[0071] The control switching rationality judgment model here takes two signals among the human-machine interface control signal or remote control signal and the logic control signal as an example. However, it can be expanded according to actual conditions during implementation. For example, if the rationality of the human-machine interface control signal, remote control signal and logic control process signal needs to be judged simultaneously, the expression is:

[0072] Y=a0+a1X1+a2X2+a3X3+ε

[0073] Similarly, if multiple signals are judged at the same time, the expression is:

[0074] Y=a0+a1X1+a2X2+…+a n X n +ε

[0075] Where: n is the number of signals to be judged;

[0076] The operation execution result is predicted based on the human-machine interface control signal or the remote control signal and the logic control signal. If the operation execution result is correct, the signal is reasonable, otherwise it is unreasonable.

[0077] Example 2

[0078] This embodiment differs from the first embodiment in that:

[0079] Specifically, the logic control module 1 controls the operation of the electrical control cabinet and also includes status monitoring. When a fault is detected in the operating status of the electrical control cabinet, the operation control related to the fault in the logic control process is suspended, and the human-machine interface and the remote server are notified at the same time for timely maintenance. The human-machine interface control signals or remote control signals involved in the maintenance process are saved in the logic control process. When the same fault occurs subsequently, the same human-machine interface control signals or remote control signals sent by the human-machine interface and the remote server are exempted from rationality judgment, and the electrical control cabinet responds directly.

[0080] Maintenance-related processes are saved in the logic control process. When the same fault occurs in the status, the logic control process can respond quickly and predict which processes will be carried out. If the process involves control signals from the human-machine interface and the remote server, the judgment step can be directly exempted, so that the electrical control cabinet can respond quickly, shorten the maintenance time of the electrical control cabinet, and minimize the impact on the operation of the electrical control cabinet.

[0081] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
