Description

Technical Field

[0001] The present invention relates to the field of parallel control technology, and in particular to a fault handling method and device for a combined process. Background Art

[0002] In the field of special vehicle control, in order to improve the simplicity, safety and reliability of user operation, a combined process is usually designed. The combined process is triggered by one-click operation to form a series of control processes, and the controlled object is controlled to complete a series of corresponding actions. The combined process consists of several serial and parallel steps. For the controlled entity or network element, each step includes execution status data such as control object identification, step sequence number, step name, step status, and execution control data such as execution conditions, control requirements, abnormal identification, and fault alarm. During the execution of the combined process, each step implements different control functions according to the execution order, execution conditions, and control requirements. When an abnormality occurs during the execution process, the pause fault mode is entered, and the corresponding fault judgment and fault handling are performed to ensure the safety of users and controlled objects. At present, in the execution of the combined process, once the abnormality of the step execution is detected, the pause fault mode will be triggered, and the step execution will be suspended for fault handling, so that the complete combined process often cannot be terminated normally, and the control purpose cannot be achieved.

[0019] When the same process step is a critical process step in the first combined sub-process, after the preceding critical process step is executed, it is determined whether the same process step triggers a suspension fault mode due to a fault.

[0038] Figure 3 FIG. 1 is a schematic diagram of the architecture of a fault handling device for a combined process according to an embodiment of the present invention. DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the present invention clearer and more understandable, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. 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 creative work are within the scope of protection of the present invention.

[0040] An embodiment of the present invention provides a method for handling a fault in a combined process. Figure 1 As shown. Figure 1 In this embodiment, the present invention comprises:

[0041] Step 100: forming a response classification for the pause failure mode of each step in the combined process and forming an alarm code corresponding to the response classification.

[0042] Those skilled in the art can understand that the work step definition can be performed in the form of a function, and the complete content of the input, output, processing conditions and processing logic of the corresponding control process can be formed through the function form definition, and then the combined process definition can be formed in the form of a function. The same work step can be reused in the combined process, including repeated execution at a certain frequency or multiple deployments in different control stages. The same work step appearing in the combined process can be determined according to objective needs and objective influences. The priority or importance level of the control node can be determined. Then, the judgment level is assigned to the graded alarm code, which is a specific working condition state of the work step to form an additional control dimension of the work step processing process, which can effectively reflect the priority or importance of the work step in different control steps or control logic of the combined process. The work step response state code is formed for the graded alarm code, and the graded state of the current work step is distinguished by the work step execution state code. For example, the pause fault mode of a work step can be assigned a graded alarm code to form different grades of the fault handling process. The pause fault mode includes the fault state and fault handling process that cause the work step to pause.

[0043] Step 200: setting the alarm code of the corresponding pause fault mode according to the priority attribute division of each step in the combined process.

[0044] The priority attribute of the work step is determined according to the priority level set or assigned to the current work step in the combined process. The priority level can be the key work step, main work step and secondary work step divided for the final realization of the combined process control purpose, or the key work step, main work step and secondary work step divided for the degree of influence on the final realization of the combined process control purpose. Setting the alarm code for the work step priority attribute can be used to initialize the processing level when the current work step appears in the corresponding control state.

[0045] Step 300: When the work step pause fault mode is triggered during the execution of the combined process, pause fault processing is performed according to the alarm code.

[0046] The pause fault mode will cause the pause fault processing to be suspended, resulting in the execution process of the work step being suspended. The real-time classification of the pause fault processing process is formed through the alarm code, and the specific execution status and execution process of the work step are marked and controlled according to the alarm code. For example, when the pause fault mode of the work step is triggered, the criticality of the work step is judged according to the default alarm code, and the execution, delay or neglect of the pause fault processing is formed. For example, the real-time classification can be changed by changing the alarm code.

[0047] In one embodiment of the present invention, the alarm code setting rules for the same process step include:

[0048] A two-level alarm code is set for the pause failure mode of the same work step, and the two-level alarm code is set as the second-class alarm code and the third-class alarm code in the system alarm system.

[0049] The fault handling method for the combined process of the embodiment of the present invention forms control optimization for the handling process of the pause fault mode by associating the pause fault mode of a single step with the importance of the single step in the local control process. It is achieved that the failure of a minor step in the combined process does not affect the execution of the key step, and the differentiated handling of the same step failure in different combined processes is achieved.

[0050] like Figure 1 As shown, in one embodiment of the present invention, based on the above embodiment, step 300 includes the following fault handling method:

[0051] Step 410: In a single-step process, when the work step (its priority attribute) is a critical work step, a second-class alarm code is set; when the work step triggers a suspend fault mode due to a fault, the single-step process is suspended; when the work step (its priority attribute) is a secondary work step, a second-class alarm code is set, and when the work step triggers a suspend fault mode due to a fault, the single-step process is suspended.

[0052] The fault handling method for the combined process in the embodiment of the present invention associates the work step processing level with the system alarm system through the alarm code, so that the alarm code will not cause processing differences of the pause fault mode during the serial control process, thereby ensuring a unified processing process for the pause fault mode.

[0053] like Figure 1 As shown, in one embodiment of the present invention, based on the above embodiment, step 300 also includes the following fault handling method:

[0054] Step 510: In the (multi-step) combined process, when the step (priority attribute) is a secondary step, a third-category alarm code is set; when the step triggers the pause fault mode for the first time due to a fault, a third-category alarm code is reported, and only the control output of the step to the controlled object is stopped; when the step triggers the pause fault mode for the second time, a second-category alarm code is reported, and the control output of the step to the controlled object is stopped.

[0055] The fault handling method for the combined process of the embodiment of the present invention associates the work step processing level with the system alarm system through the alarm code, so that the fault handling of the work step can form dynamic feedback with the system, and the control requirements of the complex process can be effectively responded to by modifying the alarm code.

[0056] like Figure 1 As shown, in one embodiment of the present invention, based on the above embodiment, step 300 also includes the following fault handling method:

[0057] Step 610: In the (multi-step) combined process, when there is a critical step (with a priority attribute) in the parallel steps, a second-class alarm code is set for the critical step. When the critical step triggers a pause fault mode due to a fault, the second-class alarm code is reported and the combined process is immediately paused, and the control output of the parallel steps to all controlled objects is stopped.

[0058] Step 620: In the (multi-step) combined process, when there is a secondary step (with a priority attribute) in the parallel step, three types of alarm codes are set for the secondary step. When the secondary step triggers the pause fault mode due to a fault, the three types of alarm codes are reported while only the control output of the controlled object of this secondary step is stopped, and other steps in the parallel step continue to be executed. The control of the key step is not affected.

[0059] The fault handling method for the combined process of the embodiment of the present invention, based on associating the process step processing level with the system alarm system through the alarm code, distinguishes the degree and direction of influence between the parallel process steps in the combined process through the alarm code, so that the influence of the suspension fault on the complete execution of the combined process and the reliability of the key control execution can be effectively balanced.

[0060] like Figure 1 As shown, in one embodiment of the present invention, based on the above embodiment, step 300 also includes the following fault handling method:

[0061] Step 710: In the combined process, determine the combined sub-process in which the same work step is located; when the same work step is in different combined sub-processes, determine the priority attribute in the corresponding sub-process, and the same work step is set to three types of alarm codes by default.

[0062] Step 720: When the same work step is a critical work step in the first combined sub-process, after the execution of the preceding critical work step, determine whether the same work step triggers a pause fault mode due to a fault. When it is determined that the pause fault mode is triggered, upgrade the third-category alarm code of the same work step to a second-category alarm code and report it, and stop immediately suspending the first combined sub-process.

[0063] Step 730: When the same process step is a minor process step in the second combined sub-process, after the preceding critical process step is completed, it is not determined whether the same process step triggers a pause failure mode due to a fault, and the subsequent critical process steps are continued to complete the second combined sub-process.

[0064] The fault handling method for the combined process in the embodiment of the present invention associates the work step processing level with the system alarm system through alarm codes, and identifies the priority level of the same work step in each combined sub-process through alarm codes, thereby forming flexible processing timing and processing logic for the pause fault mode of the same work step, thereby meeting the fault handling requirements and efficiency of complex combined processes.

[0065] The application process of the fault handling method for the combined process according to the embodiment of the present invention is as follows: Figure 2 As shown. Figure 2 In the process, for the parallel steps in the combined process, the key steps and secondary steps are determined. When the key step triggers a pause fault, all parallel steps in the combined process are paused until the user sends a process continuation instruction. When a secondary step triggers a pause fault, only the secondary step is terminated to keep the combined process going. Furthermore, when a key step (necessary sub-step) in the subsequent steps of the parallel step triggers a pause fault, even if the previous step of the subsequent step is a secondary step, the key step will also raise the alarm code, causing all steps in the combined process to pause. The control of the combined process is achieved through the step classification and the alarm code classification of the pause fault to form a regulation mechanism for secondary feedback in the key control purpose.

[0067] A memory, used to store program codes of the fault handling method for the combined process in the above embodiment during the processing;
