It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.

Example 1
Fig. 1 is a flowchart of a dynamic loading method of a configuration file according to an embodiment of the present invention, where the embodiment may be applied to a virtual machine in an industrial control operating system, and in the running process, the update condition of the configuration file is detected in real time, and the updated condition of the configuration file of the virtual machine is dynamically loaded. As shown in fig. 1, the method includes:
s110, after being triggered and started by the industrial control operating system, the first virtual machine configuration file stored currently is initialized and loaded from the target storage area, and a 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 and run in the industrial control operating system, and the industrial control operating system triggers starting or stopping of the virtual machine. If the configuration information of the virtual machine needs to be updated, a new virtual machine configuration file can be built 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 a specific example, if the industrial operating system is an Interwell operating system, the industrial system development tool may be a Intewell Developer tool. Further, the hardware platform comprises a target storage area for storing configuration files 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 triggers start-up. The file identifier of the first virtual machine configuration file may be a cryptographic hash function value in the first virtual machine configuration file, or information for uniquely identifying one virtual machine configuration file such as an update time of the virtual machine configuration file.
When the cryptographic hash function value in the virtual machine configuration file is selected as the reference identifier, the cryptographic hash function value cannot be directly obtained from the virtual machine configuration file, and the cryptographic hash function value can be obtained by calculating the relevant parameters in the virtual machine configuration file.
And S120, in the running process of the virtual machine, each time the configuration file updating checking condition is detected, acquiring the identification of the second virtual machine configuration file currently stored in the target storage area as a comparison identification.
Preferably, a timer (for example, timing 10 minutes, thirty minutes, etc.) with a preset duration may be set in the virtual machine, where the timer may work cyclically in the working state of the virtual machine, that is, after the timing reaches the preset duration, it is determined that the configuration file update checking condition is detected, and then a new round of timing may be started, so as to achieve the technical effect of periodically meeting the configuration file update checking condition.
Accordingly, each time a profile update check condition is detected, it may specifically include:
and determining the detected configuration file updating check condition every time the preset check waiting time is reached.
The update checking condition of the configuration file may be understood as a condition for triggering update checking of the configuration file of the virtual machine. Of course, it is understood that, in addition to the periodic configuration file update check by using a timer, the configuration file update check condition may be set according to the current running state of the virtual machine, for example, the configuration file update check condition is determined to be satisfied whenever the number of tasks running in the virtual machine is less than or equal to a preset task number threshold, or the configuration file update check condition is determined to be satisfied whenever the CPU occupancy of the virtual machine is less than or equal to a preset occupancy threshold, or the like, which is not limited in this embodiment.
Further, the preset time length and the preset checking waiting time length in the timer can be the same time length, and the timer reaches the preset checking waiting time length in a timing mode and can be used as a configuration file updating checking condition of the virtual machine.
The obtaining, as the comparison identifier, the identification identifier of the second virtual machine configuration file currently stored in the target storage area may specifically include:
and calculating a second password hash function value of the second virtual machine configuration file as an 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 checking condition is detected, if the configuration file is updated, the second virtual machine configuration file is different from the first virtual machine configuration file, and is changed to an updated configuration file, 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 cryptographic hash function value may refer to a cryptographic hash function value obtained by calculation of 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 identification is not consistent with the reference identification, dynamically loading a second virtual machine configuration file from the target storage area.
Dynamic loading may be understood as loading a second virtual machine configuration file from the target storage area by the virtual machine while the virtual machine remains operational.
If the comparison identifier is inconsistent with the reference identifier, the second virtual machine configuration file is dynamically loaded from the target storage area, which may specifically include:
by executing the configuration file checking function, if the comparison identifier is not consistent with the reference identifier, activating a configuration file updating task;
and dynamically loading the second virtual machine configuration file from the target storage area by executing the configuration file updating task.
Preferably, the virtual machine may further include a pre-built configuration file checking function, after the detected configuration file updating checking condition is determined, the configuration file checking function may be triggered, and the configuration file checking function may be used to determine whether the comparison identifier is consistent with the reference identifier, if so, it may be determined that the virtual machine configuration file does not need to be updated, and if not, it may be determined 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, and when the virtual machine needs to update the configuration file, the configuration file update task can be kept in a dormant state and exist in an operating environment of the virtual machine, and when the virtual machine needs to update the configuration file, the configuration file update task can be triggered through a corresponding checking result obtained by a configuration file checking function. The triggered configuration file updating task can be used for dynamically loading a new virtual machine configuration file from the target storage area under the working 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, a 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 implement updating of 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 take each start as a node for loading the current configuration file from the target storage area, so the invention provides a mode of checking the update condition of the configuration file of the virtual machine at fixed time and dynamically loading the new configuration file, and avoids the condition of interrupting the running state of the virtual machine because the configuration file of the virtual machine needs to be updated.
According to the technical scheme, the reference mark in the currently stored virtual machine configuration file is compared with the comparison mark in the virtual machine configuration file updated last time at regular time by the virtual machine running in the industrial control operation system, the currently stored virtual machine configuration file is dynamically loaded when the two marks are inconsistent, the updating condition of the configuration file can be timely checked under the working state of the virtual machine, and when the virtual machine configuration file needs to be updated, the virtual machine configuration file can be effectively dynamically loaded, the continuous work of the virtual machine in the industrial control operation 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 of a configuration file according to a second embodiment of the present invention, where the dynamic loading method of the configuration file is further embodied on the basis of the foregoing embodiment. As shown in fig. 2, the method includes:
s210, after being triggered and started by the industrial control operating system, a configuration file updating task is created, and a timer with a preset time duration is started to start timing.
Further, after creating the configuration file update task, the method may further include:
the profile update task is set to a dormant state.
The configuration file updating task is only used for executing the task of updating the configuration file of the virtual machine, and the configuration file updating task is in a dormant state before being triggered or after successfully executing the task of updating the configuration file of the virtual machine.
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 selected from MD5 (Message Digest Algorithm, fifth version of message digest algorithm), and the calculated MD5 value of the first virtual machine configuration file is stored as the reference identifier.
The advantages of this arrangement are that: as the MD5 value of one file is changed 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 selected as a reference mark of the virtual machine configuration file, so that the change condition of the virtual machine configuration file can be accurately identified.
And S230, in the running process of the virtual machine, controlling the timer to count again every time the timer is detected to count the time duration, and triggering and executing a pre-constructed configuration file checking function.
S240, acquiring the identification of the second virtual machine configuration file currently stored in the target storage area as the comparison identification by executing the configuration file checking function.
S250, executing a configuration file checking function, and if the comparison identifier is not consistent with the reference identifier, triggering to execute a pre-built configuration file activation sub-function.
The configuration file activation sub-function may be a sub-function in the configuration file checking function, and may be triggered to run when the configuration file checking function detects that the comparison identifier is inconsistent with the reference identifier, and may be used to activate a configuration file update task.
In a specific embodiment, the identification identifier of the second virtual machine configuration file may also select an MD5 value, and by comparing the MD5 value of the second virtual machine configuration file with the MD5 value of the first virtual 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 inconsistent with the reference identifier, it may be determined that the configuration file of the virtual machine needs to be updated, thereby triggering execution of the pre-built configuration file activation sub-function.
S260, activating a configuration file update task by executing a configuration file activation subfunction.
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 taking the identification mark of the second virtual machine configuration file as a new reference mark for updating and storing.
The purpose of this arrangement is that: because the configuration file may need to be updated not only once in the running process of the virtual machine, the identification identifier of the configuration file of the second virtual machine can be stored as a new reference identifier, so that the configuration file can 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:
the profile update task is reset to the dormant state.
According to the technical scheme, the configuration file updating task is set to be in the dormant state when the configuration file is not updated, and after the configuration file of the second virtual machine is dynamically loaded from the target storage area, the identification mark of the configuration file of the second virtual machine is used as a new reference mark, so that the configuration file of the virtual machine can be updated for multiple 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.
Specific application scene
The specific application scenario is an optional dynamic loading method of configuration files, and in the specific application scenario, an industrial control operating system is selected from an Interwell operating system, and an industrial system development tool is a Intewell Developer tool. The Interwell system and the virtual machine run in one hardware platform at the same time, and the virtual machine can be loaded and run in the Interwell operating system. If the configuration information of the virtual machine needs to be updated, a new virtual machine configuration file can be constructed by using Intewell Developer tools through another PC, and the virtual machine configuration file is downloaded to the hardware platform.
Further, a task of updating the configuration file can be created in the virtual machine, and the task of updating the configuration file is set to be in a dormant state; a timer with preset time length can be arranged in the virtual machine, and after the timer reaches the preset time length, the timing state can be reset, and the time is circularly counted; a function for detecting the configuration file can also be created in the virtual machine, the function for detecting the configuration file is triggered at intervals by timer control, and a sub-function for triggering the task for updating the configuration file can also be included in the function for detecting the configuration file.
After the Interwell operating system starts the virtual machine, the MD5 value in the current configuration file of the virtual machine can be calculated as a reference mark, a timer is started, a function for starting the detection configuration file can be triggered every time the preset time length of the timer is reached, the function can acquire the MD5 value of the configuration file in the current target storage area as a comparison mark, the reference mark is compared with the comparison mark, if the reference mark is consistent with the comparison mark, the configuration file of the virtual machine can be judged to be not updated, and if the reference mark is inconsistent with the comparison mark, the configuration file of the virtual machine can be judged to be updated.
If the configuration file of the virtual machine needs to be updated, a sub-function for triggering the task for updating the configuration file in the function for detecting the configuration file can be called, and the task for updating the configuration file is triggered, so that the task for updating the configuration file loads a new configuration file, and the configuration file of the virtual machine is updated.
Further, after the configuration file of the virtual machine 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 dormant state.
