Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The embodiment of the invention provides an execution method of a carrier rocket measurement and control flow engine, as shown in fig. 1, comprising the following steps:
s110, constructing a data table for measurement and control flow information of the carrier rocket based on the configuration file.
In order to better understand the technical solution of the present application, the concept of the following flow engine is first introduced here. The flow engine is an important component of the test launch control software, belongs to a general processing module, is responsible for the scheduling control command or the test flow of the carrier rocket, and has no requirement on the execution content of specific services. The flow engine has the functions of analyzing and scheduling the test flow of the carrier rocket, executing a command or a calculation program according to a certain rule according to a control logic defined by a user, monitoring the execution state and timely performing exception handling.
The test instruction is generally triggered by an interaction event on the software interface (for example, a user sends a certain operation instruction), or can be triggered by a background periodic task at fixed time, and the executed result data and state data are written into a corresponding memory in real time and can be fed back to the software interface as required.
The functions that the flow engine may provide include: providing a function of executing a service, providing a data access function, providing a function of executing a periodic flow, and providing a function of supporting execution of a nested flow:
the function of providing executive service is mainly called by external interface, and a flow item is started and executed according to the input parameters. The execution process comprises the following steps: and according to the analyzed flow steps, sequentially executing the steps in sequence, judging the category of the flow step for each specific flow step, and selecting a corresponding execution branch. After each step is executed, judging the execution state, if the step is passed, continuing to execute the next step, if the step is not passed, stopping the flow, and prompting an error.
The flow engine may provide data access functionality:
in the execution process of the flow steps, data needs to be acquired from outside, and after the execution is finished, the data or the execution state needs to be updated, so that the flow engine module has the function of reading and writing the external data. Such as querying and reading the latest value of the specified data via the interface.
For example, assuming that the designated data is a stand-alone power distribution state, when the stand-alone power distribution is successful, the value of the power distribution state may be changed from 0 to 1, then the latest value is 1, and the latest value is returned.
The function of writing data is: and calling a write data interface, converting the appointed data into binary data of a corresponding data type, and storing the binary data into an appointed data storage area.
The flow engine has a function of executing a periodic flow:
in an actual application scenario, there are tasks that need to be periodically executed at certain time intervals, and the flow engine can support the periodic tasks. The periodic tasks are divided into two types, namely, the periodic tasks are triggered by an external command and repeatedly executed according to a set period after being started; and secondly, starting by default, automatically starting a task after the module is loaded, and repeatedly executing according to a set period.
The flow engine starts the thread executed on time, and the function of the thread is periodically called to execute by the functional module according to the set time interval.
To facilitate flow multiplexing, the flow engine also supports execution of nested flows:
the nested process means that the process step is also a sub-process step, and the process engine needs to analyze the situation, so as to ensure the normal execution of the process step.
For example, when the launch vehicle performs the testing and launching process, there are many process steps, such as when performing the launching task, the overall process steps include: distribution, performing inspection, interpretation of data results, and the like. The power distribution flow comprises the following steps: the power distribution of the single machine A, the power distribution of the single machine B, the power distribution of the single machine C and the checking of the power distribution state of each single machine are carried out, so that the total flow step and the power distribution flow step are a nested flow, and when the power distribution flow step is executed, the configuration file still needs to be analyzed to obtain the sub-flow steps contained in the power distribution flow step, thereby executing the flow steps in sequence.
When the test flow item changes or the test flow item is newly added, in order to avoid modifying a large number of codes, a configuration file is preset, and the configuration file contains measurement and control flow information when the carrier rocket executes the test and launch tasks. Each test flow item may correspond to a separate configuration file, or may correspond to a total configuration file.
When executing the test item or the launching item, in order to realize the calling and execution of the flow information, the configuration file needs to be analyzed to obtain various measurement and control flow information of the carrier rocket, and a corresponding data table is constructed for the measurement and control flow information.
In one embodiment, constructing a data table for measurement and control flow information based on a configuration file includes:
analyzing the configuration file to obtain each flow item contained in the measurement and control flow information, the flow step contained in the flow item, the function module called by the flow step, the execution condition of each flow step and the data information required after executing the flow step;
creating a corresponding data table for the flow item, the flow step, the function module called by the flow step, the execution condition of the flow step and the data information required after the flow step is executed respectively; wherein the data table comprises: field name, data type, field meaning, and remark information.
Specifically, after the configuration file is parsed, all measurement and control flow information in the configuration file can be obtained, including: the method comprises a flow item, flow steps contained in the flow item, a function module called by the flow steps, execution conditions of each flow step and data information needed after the flow steps are executed. The process item comprises the following steps: the names of the flow items, whether the flow items are periodic flow tasks, the execution period of the periodic tasks, whether default starting and the like, and the data tables corresponding to the flow items are shown in table 1:
TABLE 1
The flow steps comprise: step number, the number of the process item to which the process step belongs, step category, step information, etc., and the corresponding data table is shown in table 2:
TABLE 2
The functional module called by the flow step comprises: the number of the functional module, the number of the process step to which the functional module belongs, input parameters and the like, and the corresponding data table is shown in table 3:
TABLE 3 Table 3
The execution conditions of the flow steps include: the corresponding data table is shown in table 4, including the condition number, the sequence number of the flow step, the condition type, the data number, the data type number, the expression, etc.:
TABLE 4 Table 4
The data information required after executing the flow steps includes: the sequence numbers of the flow steps, the sequence numbers of the data, the corresponding data values and the like, and the data table is shown in table 5:
TABLE 5
S111, when the measurement and control task of the carrier rocket needs to be executed, determining a flow item mapping table based on the data table.
After the data table of the measurement and control flow information is built, when the measurement and control task of the carrier rocket needs to be executed, a flow engine is started, and then the flow engine initializes (analyzes) the data table to obtain each flow entity object, and the flow entity objects are stored in a flow item mapping table.
The process entity object can be understood as each process step, and for each process step in the process item mapping table, the process entity object can be executed as one process entity object, and if the execution is successful, the next process entity object is continued; if the execution fails, the execution is terminated. And the execution process can be paused, resumed or terminated according to the user's requirements during the execution of the process steps.
In one embodiment, determining a flow item mapping table based on a data table includes:
reading flow item data from a data table corresponding to the flow item information;
storing the names of the flow items in the flow item data into key value items in the flow item mapping table;
traversing each flow item name in the flow item mapping table, and searching a flow step contained in each flow item name in a data table corresponding to the flow step based on the flow item name;
storing the flow steps contained in each flow item name into the value item in the flow item mapping table; wherein key and value are a key-value pair.
In one embodiment, the method further comprises:
traversing all value items in the flow item mapping table to obtain corresponding flow steps;
if the type of the flow step is determined to be the service type, searching for input parameters in a data table corresponding to the function module called in the flow step, and storing the service output parameters as attribute information in a flow item mapping table;
if the type of the flow step is determined to be the condition type, searching the execution condition information in a data table corresponding to the execution condition of the flow step, and storing the execution condition information as attribute information in the flow item mapping table;
if the type of the flow step is determined to be a storage type, searching a corresponding data object in a data table corresponding to the data information required after the flow step, and storing the data object as attribute information in a flow item mapping table; the data object includes: data type, data value, and data sequence number.
In one embodiment, the method further comprises:
acquiring task types of flow items in measurement and control flow information;
and saving the flow item with the task type being the periodic task into a periodic flow list, and adding a corresponding execution state into the periodic flow list.
In this embodiment, the task types of some flow items are periodic, and the task types can be automatically and periodically executed without external triggering conditions; some of the process items are non-periodic in task type and require an external trigger condition (e.g., satisfying a certain execution condition or receiving a trigger instruction from an external user). Therefore, the process items of the periodic tasks need to be screened out, and errors in the follow-up measurement and control process are avoided.
The method is equivalent to connecting each flow item, the used flow step, the execution condition corresponding to the flow step, the functional module used by the flow step and the data required to be acquired after the flow step is executed in series, and the required information is conveniently searched in the flow item mapping table when the test task is executed in the follow-up.
S112, obtaining a target flow item name to be executed, and searching a flow entity object contained in the target flow item in a flow item mapping table according to the target flow item name.
When executing the measurement and control flow, the flow engine is a specific implementation for providing functional services externally, so that the target flow item name to be executed needs to be obtained from the input parameters, and the flow entity object contained in the target flow item is searched in the flow item mapping table according to the target flow item name.
It can be understood that, because the names of the flow items are stored in the flow item mapping table, the flow steps corresponding to the flow items; therefore, after the names of the flow items are determined, the corresponding flow entity objects can be searched in the flow item mapping table according to the names of the flow items.
S113, executing each flow entity object.
In one embodiment, executing each flow entity object includes:
when the flow entity object is a non-periodic flow, acquiring an object type of the flow entity object;
if the object type is the service type, calling a service function module corresponding to the flow entity object, and transmitting parameters required by the service function module;
if the object type is the nested type, continuing to analyze the streaming entity object, and executing corresponding operation according to the analysis result;
if the object type is a delay type, executing a waiting command;
if the object type is the condition type, acquiring corresponding state information after executing the flow entity object, and continuing to execute the subsequent flow according to the state information;
and if the object type is the storage type, storing the data information obtained after the execution of the flow step.
In one embodiment, executing each flow entity object includes:
when the process entity object is a periodic process, traversing a periodic process list to obtain each periodic process;

Specifically, when executing each aperiodic flow entity object, the following five object types are included:
1. service type
At this time, the corresponding service function module needs to be called, and parameters needed by the service function module book are transmitted.
2. Nested measurement type
If the flow entity object is of a nested type, the flow entity object is described as a nested flow, and the flow entity object needs to be parsed at this time, which refers to the specific implementation process in step S110.
3、waitTime
And if the delay type is the delay type, performing delay processing and executing a waiting command.
4. Condition type condition
At this time, the subsequent specific execution operation needs to be determined according to the execution condition, wherein the execution condition comprises a plurality of computing functions, which are mainly used for obtaining the condition determination result and are classified into more than, more than or equal to, not equal to, less than or equal to, and further comprise computing functions such as computing expressions, expression conversion and the like.
After the execution of a certain step of the process is completed, the corresponding result or state information needs to be acquired to determine how to execute the next step.
5. Storage type save
Executing the data storage flow, and sequentially writing each data to be stored into the corresponding data area.
When the periodic flow entity object is executed, after the flow engine is loaded, the periodic flow list is traversed, and an independent thread is created for each periodic flow entity object to schedule and execute.
In the execution function of the thread, task information of the process entity object is firstly obtained, and then the process task is periodically executed according to a set time interval. Before each period is executed, the start-stop state of the flow entity object is judged according to the state data of the data area.
According to the embodiment of the invention, the measurement and control flow information in the running process of the carrier rocket measurement and control software is generalized and abstracted, the measurement and control flow information is summarized into the flow items, the steps included in the flow, the functional modules called in the steps, the execution conditions, the data storage and other data tables, and the data tables are analyzed and processed, so that the unified and standardized processing of the test flow is realized.
