It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example one
Fig. 1 is a flowchart of a method for dynamically loading a configuration file according to an embodiment of the present invention, where the embodiment is applicable to a virtual machine in an industrial control operating system, and detects an update condition of the configuration file in real time during a running process, and dynamically loads a condition of an updated virtual machine configuration file, the method may be executed by a dynamic loading device of the configuration file, the dynamic loading device of the configuration file may be implemented in a form of hardware and/or software, and the dynamic loading device of the configuration file may generally be configured in a virtual machine having a data processing function. As shown in fig. 1, the method includes:
s110, after the industrial control operating system is triggered and started, the currently stored first virtual machine configuration file is loaded from the target storage area in an initialization mode, and the file identification of the first virtual machine configuration file is stored as a reference identification.
Optionally, in a hardware platform running the industrial control operating system and the virtual machine at the same time, the virtual machine may be loaded in the industrial control operating system to run, and the industrial control operating system triggers the start or stop of the virtual machine. If the configuration information of the virtual machine needs to be updated, a new virtual machine configuration file can be constructed by using an industrial system development tool through another terminal device (typically, a PC), and the virtual machine configuration file is downloaded to the hardware platform.
In one specific example, if the industrial control operating system is an Intewell operating system, the industrial system development tool may be an Intewell Developer tool. Further, the hardware platform comprises a target storage area used for storing the configuration file of the virtual machine. If the industrial system development tool in the industrial control operating system generates a new configuration file, the industrial system development tool can download the new configuration file to be stored in the target storage area and cover the original configuration file.
The first virtual machine configuration file may refer to a configuration file for configuring the virtual machine when the virtual machine is triggered to start. The file identifier of the first virtual machine configuration file may be a hash function value of a password in the first virtual machine configuration file, or information used for uniquely identifying one virtual machine configuration file, such as update time of the virtual machine configuration file.
It should be further noted that when the password hash function value in the virtual machine configuration file is selected as the reference identifier, the password hash function value cannot be directly obtained from the virtual machine configuration file, and the password hash function value may be obtained only by calculating the relevant parameters in the virtual machine configuration file.
And S120, in the running process of the virtual machine, when the updating and checking condition of the configuration file is detected, acquiring the identification mark of the second virtual machine configuration file currently stored in the target storage area as a comparison mark.
Preferably, a timer with a preset time duration (e.g., timing for 10 minutes, thirty minutes, etc.) may be set in the virtual machine, and the timer may work cyclically in the operating state of the virtual machine, that is, after the time duration reaches the preset time duration, it is determined that the configuration file update check condition is detected, and then a new round of time duration may be started, so as to achieve the technical effect of periodically satisfying the configuration file update check condition.
Correspondingly, each time the configuration file update checking condition is detected, the method may specifically include:
the detected profile update check condition is determined every time a preset check waiting time period is reached.
The update check condition of the configuration file may be understood as a condition for triggering an update check of the configuration file of the virtual machine. Of course, it is understood that, in addition to the periodic profile update check by using the timer, the profile update check condition may be set according to the current operating state of the virtual machine, for example, the profile update check condition is determined to be satisfied every time the number of tasks running in the virtual machine is less than or equal to the preset task number threshold, or the profile update check condition is determined to be satisfied every time the CPU occupancy rate of the virtual machine is less than or equal to the preset occupancy rate threshold, and the like, which is not limited in this embodiment.
Further, the preset duration in the timer and the preset check waiting duration may be the same duration, and the duration when the timer reaches the preset check waiting duration may be used as a configuration file update check condition of the virtual machine.
The obtaining of the identification identifier of the second virtual machine configuration file currently stored in the target storage area as the comparison identifier may specifically include:
and calculating a second password hash function value of the second virtual machine configuration file as a comparison identifier.
The second virtual machine configuration file may refer to a currently stored configuration file obtained from the target storage area when the configuration file update check condition is detected, and if the configuration file is updated, the second virtual machine configuration file is different from the first virtual machine configuration file and is changed into an updated configuration file, and if the configuration file is not updated, the second virtual machine configuration file is the same as the original first virtual machine configuration file; the second password hash function value may refer to a password hash function value obtained by performing calculation using a relevant parameter in the second virtual machine configuration file.
The comparison identifier may be used to compare with the reference identifier, so as to further determine whether the virtual machine needs to dynamically load the second virtual machine configuration file from the storage area, and a specific comparison manner will be described in detail later.
S130, if the comparison identifier is determined to be inconsistent with the reference identifier, dynamically loading a second virtual machine configuration file from the target storage area.
Dynamic loading may be understood as the virtual machine loading a second virtual machine configuration file from the target storage area while the virtual machine remains in an operational state.
If it is determined that the comparison identifier is inconsistent with the reference identifier, dynamically loading the second virtual machine configuration file from the target storage area may specifically include:
by executing a configuration file check function, if the comparison identifier is determined to be inconsistent with the reference identifier, activating a configuration file updating task;
the second virtual machine configuration file is dynamically loaded from the target storage area by performing a configuration file update task.
Preferably, the virtual machine may further include a pre-constructed configuration file check function, after determining the detected configuration file update check condition, the configuration file check function may be triggered, and the configuration file check function may be configured to determine whether the comparison identifier is consistent with the reference identifier, and if so, may determine that the virtual machine configuration file does not need to be updated, and if not, may determine that the virtual machine configuration file needs to be updated.
Optionally, the configuration file update task is a task created in advance in the virtual machine, when the configuration file of the virtual machine does not need to be updated, the configuration file update task may remain in a dormant state and exist in an operating environment of the virtual machine, and when the configuration file of the virtual machine needs to be updated, the configuration file update task may be triggered through a corresponding check result obtained by the configuration file check function. The triggered configuration file update task may be used to dynamically load a new virtual machine configuration file from the target storage area in the operating state of the virtual machine.
In a specific embodiment, after the configuration file checking function determines that the virtual machine configuration file needs to be updated, the configuration file updating task may be activated, and by executing the configuration file updating task, the second virtual machine configuration file may be dynamically loaded from the target storage area, so as to update the virtual machine configuration file.
It can be understood that, in the prior art, the virtual machine cannot detect the change of the configuration file, and only can use each startup as a node for loading the current configuration file from the target storage area, so the present invention proposes a manner of regularly checking the update condition of the virtual machine configuration file and dynamically loading a new configuration file, thereby avoiding the condition of interrupting the running state of the virtual machine due to the need of updating the virtual machine configuration file.
According to the technical scheme of the embodiment of the invention, the reference identifier in the currently stored virtual machine configuration file is compared with the comparison identifier in the latest updated virtual machine configuration file at regular time by the virtual machine running in the industrial control operating system, and the updating condition of the configuration file can be timely checked in the working state of the virtual machine in a mode of dynamically loading the currently stored virtual machine configuration file when the two identifiers are inconsistent, and the virtual machine configuration file can be effectively and dynamically loaded when the virtual machine configuration file needs to be updated, so that the continuous work of the virtual machine in the industrial control operating system can be ensured, the working efficiency of the virtual machine is effectively improved, and the real-time requirement of an industrial control scene is met to the greatest extent.
Example two
Fig. 2 is a flowchart of a dynamic loading method for a configuration file according to a second embodiment of the present invention, and the present embodiment further embodies the dynamic loading method for the configuration file on the basis of the above embodiment. As shown in fig. 2, the method includes:
s210, after the industrial control operating system is triggered and started, a configuration file updating task is created, and a timer with preset timing duration is started to start timing.
Further, after creating the configuration file update task, the method may further include:
and setting the configuration file updating task to be in a dormant state.
The configuration file updating task is only used for executing the task of updating the virtual machine configuration files, and the configuration file updating task is in a dormant state before being triggered or after the task of updating the virtual machine configuration files is successfully executed.
S220, calculating a first password hash function value of the first virtual machine configuration file, and storing the first password hash function value as a reference identifier.
In a specific embodiment, the cryptographic hash function value may be an MD5 (Message Digest Algorithm, fifth version of the Message Digest Algorithm 5) value, and the MD5 value of the calculated first virtual machine configuration file is stored as the reference identifier.
The advantages of such an arrangement are: because the MD5 value of a file changes after any data in the file is changed, the MD5 value can be used as a unique identification value of the file, and the MD5 value is used as a reference identifier of the virtual machine configuration file to accurately identify the change condition of the virtual machine configuration file.
And S230, in the running process of the virtual machine, controlling the timer to count again and triggering and executing a pre-constructed configuration file checking function when the timer is detected to count to the timing duration.
S240, acquiring the identification mark of the second virtual machine configuration file currently stored in the target storage area as a comparison mark by executing the configuration file check function.
And S250, by executing the configuration file check function, if the comparison identifier is determined to be inconsistent with the reference identifier, triggering and executing a pre-constructed configuration file activation sub-function.
The configuration file activating sub-function may be a sub-function in the configuration file checking function, and when the configuration file checking function detects that the comparison identifier is inconsistent with the reference identifier, the configuration file activating sub-function may be triggered to run, and the configuration file activating sub-function may be used to activate a configuration file updating task.
In a specific embodiment, the identification identifier of the second virtual machine configuration file may also be an MD5 value, and by comparing the MD5 value of the second virtual machine configuration file with the MD5 value of the first virtual machine configuration file, it may be simply and intuitively determined whether the comparison identifier is consistent with the reference identifier, and if the comparison identifier is not consistent with the reference identifier, it may be determined that the configuration file of the virtual machine needs to be updated, so as to trigger execution of a pre-constructed configuration file activation subfunction.
And S260, activating a configuration file updating task by executing a configuration file activating sub-function.
And S270, dynamically loading the second virtual machine configuration file from the target storage area by executing the configuration file updating task.
Further, after dynamically loading the second virtual machine configuration file from the target storage area, the method may further include:
and updating and storing the identification mark of the second virtual machine configuration file as a new reference mark.
The purpose of this is to: in the running process of the virtual machine, the configuration file may need to be updated more than once, so that the identification identifier of the second virtual machine configuration file can be stored as a new reference identifier, and the configuration file can be ensured to be updated normally next time.
Further, after dynamically loading the second virtual machine configuration file from the target storage area by performing the configuration file update task, the method may further include:
and resetting the configuration file updating task to be in a dormant state.
According to the technical scheme of the embodiment of the invention, the mode that the configuration file updating task is set to be in the dormant state when the configuration file is not updated, and the identification mark of the second virtual machine configuration file is used as the new reference mark after the second virtual machine configuration file is dynamically loaded from the target storage area is adopted, so that the virtual machine configuration file can be updated for many times in the running process of the virtual machine, the continuous work of the virtual machine is realized, and the working efficiency of the virtual machine is improved.
Application specific scenarios
The specific application scenario is a dynamic loading method of an optional configuration file, in the specific application scenario, an Intewell operating system is selected as an industrial control operating system, and an industrial system development tool is an Intewell Developer tool. The Intewell system and the virtual machine run in a hardware platform at the same time, and the virtual machine can be loaded in the Intewell operating system and run. If the configuration information of the virtual machine needs to be updated, a new virtual machine configuration file can be constructed by using an Intewell Developer tool through another PC, and the virtual machine configuration file is downloaded to the hardware platform.
Further, a task for updating the configuration file can be created in the virtual machine, and the task for updating the configuration file is set to be in a dormant state; a timer with preset time length can be set in the virtual machine, and the timer can reset the timing state and count time circularly after the timer counts time to the preset time length; the method can also create a function for detecting the configuration files in the virtual machine, the function for detecting the configuration files is triggered at intervals through timer control, and a sub-function for triggering a task of updating the configuration files can be further included in the function for detecting the configuration files.
After the Intewell operating system starts the virtual machine, the MD5 value in the current configuration file of the virtual machine may be calculated as a reference identifier, and a timer is started, and when a preset time duration of the timer is reached, a function for starting a detection configuration file may be triggered, and the function may acquire the MD5 value of the configuration file in the current target storage area as a comparison identifier, and compare the reference identifier with the comparison identifier, if the reference identifier is consistent with the comparison identifier, it may be determined that the configuration file of the virtual machine does not need to be updated, and if the reference identifier is inconsistent with the comparison identifier, it may be determined that the configuration file of the virtual machine needs to be updated.
If the configuration file of the virtual machine needs to be updated, a subfunction used for triggering a task of updating the configuration file in the functions of the detection configuration file can be called, and the task of updating the configuration file is triggered, so that the task of updating the configuration file loads a new configuration file, and the updating of the configuration file of the virtual machine is realized.
Further, after the virtual machine configuration file is updated, the MD5 value of the updated configuration file may be used as a new reference identifier, and the task of updating the configuration file may be reset to the sleep state.
