Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The component dynamic management method provided by the embodiment of the invention can be applied to the modularized product shown in the figure 1; the coordinate (0, 0) module is defined as a main control module, and the main control module comprises a CPU, a memory, a power supply and an expansion port; the coordinate (0, 2) module is a first component, comprising an IoT (THE INTERNET of Things, internet of things) module, such as bluetooth, zigBee, etc.; the coordinate (1, 1) module is a second component and comprises a Wi-Fi module; the coordinate (-1, 1) module is a third component, comprising a WWAN (wireless wide area network) module, such as LTE,5G, etc. In addition, the modular design can remove the coupling among components, so that a user can conveniently customize, replace and upgrade according to favorite functions; the main control modules (0, 0) are physically coupled with the components through electrical interfaces, the main control modules are used as necessary modules in the modularized product architecture, and other components can be freely added and deleted according to requirements; for example, the master control module (0, 0) is coupled with the second component (1, 1) to form a wireless Wi-Fi router; the main control module (0, 0) is coupled with the second component (1, 1) and the third component (-1, 1) to form a Wi-Fi gateway with wireless broadband access. It should be noted that, the main control module and the components may be various combined functional modules, and the components may be expanded to superimpose functions according to functional requirements, which is not limited herein.
In the modularized product provided in this embodiment, the components are managed in the main control module in a plug-in loading manner, so that a component information list is stored in the main control module, the component information list includes each component successfully identified by the main control module and component information corresponding to each component successfully identified by the main control module, and any piece of component information includes a component unique ID, a Base address+offset size of a component mirror image, and a component state (see fig. 2); the Base address+offset size of the component image refers to an address space for storing the component image correspondingly; component state refers to the current state of a defined component, e.g., a component that is identified as successful and loaded may be defined as a "connect successful" state; components that are identified as successful but unloaded may be defined as "disconnected" states; components that are identified as successful and loaded, but removed by the user, may also be defined as "disconnected" states. In addition, the arrangement order of the components in the component information list may be determined according to the definition of the modular product, the use occasion, and other factors, which is not particularly limited in this embodiment.
Referring to fig. 3, a flow chart of a method for dynamically managing components according to an embodiment of the present invention includes the following steps:
S11, acquiring a first component information list;
S12, loading a component mirror image according to the first component information list, and performing heartbeat monitoring on the current component on which the mirror image is being loaded;
S13, judging whether the first component information list needs to be updated according to the heartbeat monitoring result;
s14, acquiring a second component information list after loading of all components is completed;
S15, when the components to be removed exist in the second component information list, the mirror image space of the components to be removed is tidied;
S16, adjusting the master control Boot image according to the arrangement result.
In this embodiment, the master control mirror image loads the components in sequence according to the information of the first component information list, and under the condition that any component is not accessed, the first component information list may be empty. When a plurality of components are accessed, corresponding component information items are added into a first component information list, and the loading sequence of each component is determined by the system design according to the factors of modular product definition, use occasions and the like.
By arranging the mirror image space of the component to be removed and adjusting the master control Boot mirror image according to the arrangement result, the condition that the component is wasted in the system storage space due to the actual requirement of a user or the internal damage of the component can be effectively relieved, and the flexibility of expanding the function of the component and the utilization rate of the expanded component in the communication equipment are improved.
Referring to fig. 4, a flow chart of a method for managing a component loading stage according to an embodiment of the present invention is shown;
The step of judging whether the first component information list needs to be updated according to the heartbeat monitoring result specifically comprises the following steps:
When the current component which is loading the mirror image does not have a heartbeat signal, stopping loading the current component, and updating the first component information list;
When the heartbeat signal exists in the current component which is loading the image, the current component is continuously loaded.
Specifically, if the heartbeat monitoring result of the current component is that the heartbeat signal is not monitored, updating the component state in the component information corresponding to the current component to a state such as "disconnection"; if the heartbeat monitoring result of the current component is that the heartbeat signal is monitored, the current component is continuously loaded. The heartbeat signal is output by the component and is physically connected to the main control module through the coupling interface, the heartbeat signal can be a square wave signal with the period of 0.5s and the duty ratio of 50%, and the heartbeat signal is output by the oscillating circuit of the component and is connected to the GPIO input pin of the CPU of the main control module. The type, amplitude, frequency, etc. of the heartbeat signal in this embodiment are not particularly limited.
Further, heartbeat monitoring is periodically carried out on the current component which is loading the mirror image, and once the heartbeat monitoring result is that the heartbeat signal is not monitored, loading of the current component is stopped, and the first component information list is updated. By periodically performing heartbeat monitoring on the current component which is loading the mirror image, the phenomenon that the current component is removed in the loading process to cause component loading to hang up can be effectively avoided, and therefore system stability is improved.
In this embodiment, after loading of the current component is completed, it is further required to determine whether the current component is the last component, and if not, loading the next component according to the conditional order until all components are loaded.
Referring to fig. 5, a flow chart of a management method of a component after a loading stage according to an embodiment of the present invention is shown;
After the second component information list after all the components are loaded is obtained, the method further comprises the following steps:
judging whether a disconnected component exists in the second component information list;
If yes, judging whether a heartbeat signal exists in the disconnected component;
when no heartbeat signal exists, taking the disconnected component as a component to be removed;
when a heartbeat signal is present, the disconnected component is reloaded.
Specifically, according to each component state in the second component information list, judging whether a component with disconnected component state exists in the second component information list; if yes, judging whether the disconnected component has a heartbeat signal, and if not, taking the disconnected component as a component to be removed; when a heartbeat signal is present, the disconnected component is reloaded. In addition, after the disconnected component finishes loading, the state of the component corresponding to the disconnected component is changed into the successful connection, and the second component information list is updated. By performing heartbeat monitoring on the disconnected component, the phenomenon that the disconnected component is unloaded due to loosening of the coupling interface during loading can be effectively prevented, and therefore the utilization rate of the component is improved.
Furthermore, when the heartbeat signal exists in the disconnected component, the component can be immediately restarted and changed, or the disconnected component can be reloaded when the system is restarted next time, so that the phenomenon of deadlock caused by repeated restarting can be effectively avoided, and the system stability is improved.
Further, the component dynamic management method further comprises the following steps:
When the disconnected component does not exist in the second component information list, monitoring a heartbeat signal of the component in the second component information list;
when a heartbeat signal exists, monitoring whether an access detection signal exists or not;
if yes, the component corresponding to the access detection signal is identified.
Further, referring to fig. 6, when a heartbeat signal exists, whether an access detection signal exists is monitored, when the access signal is detected, a first component in the access signal is determined, the first component is identified by an ID, and whether the ID information of the first component is legal is determined; when the ID information of the first component is legal information, loading a first Boot image corresponding to the first component onto the main control module according to the ID information of the first component; the master control module is controlled to adjust the master control Boot image of the master control module according to the first Boot image; and restarting the system of the communication equipment after the master control Boot image is adjusted, and loading the master control module and the adjusted master control Boot image. If the access detection signal does not exist, continuing to monitor whether the access detection signal exists. The method has the advantages that by detecting the accessed component and carrying out ID identification, the Boot image corresponding to the component is loaded on the main control module, and the main control module adjusts the main control Boot image of the main control module according to the loaded Boot image, so that a new main control Boot image of the main control module is loaded after a system of the communication equipment is restarted, the discovery, identification and access of the component in the communication equipment are realized, the usability and flexibility of expanding the function of the component in the communication equipment are improved, and the cost is low; in addition, the components can be added and deleted according to actual demands, and the main control module is combined with different components, so that customization, replacement and upgrading of different functions are realized.
FIG. 7 is a schematic flow chart of a method for managing a mirror image space of a component to be removed according to the present invention;
When the component to be removed exists in the second component information list, the sorting of the mirror image space of the component to be removed specifically includes:
positioning a mirror image space address area of the component to be removed;
The mirrored spatial address region of the component to be removed is reclaimed.
Specifically, the space address area of the component image to be removed can be located by the Base address+offset size of the component image in the component information corresponding to the component to be removed, and the image content of the component to be removed is erased and released according to the erase condition limitation of the memory (for example, some systems use NAND FLASH, have limitation on the minimum unit of erase, and at this time, the system is required to perform an algorithm to determine which blocks are specifically erased).
Further, the reclaiming of the mirrored spatial address area of the component to be removed further comprises:
Judging whether the recovered mirror image space address area is required to be fused with other idle address areas or not;
If yes, moving the mirror image space address areas corresponding to other components;
and updating the second component information list after the movement is completed.
Specifically, the Base address+offset size of the component image in the component information corresponding to the component to be removed can be used for positioning the component image space address area to be removed, judging whether the image space address area is located at the last section of the occupied address interval in the component image address space defined by the system, if not (that is, the rear section of the component image space address area to be removed also has the mirror image of other components), fusing the recovered image space address area with other idle address areas, and at the moment, moving the image space address area corresponding to other components, for example, in fig. 8, lifting up the mirror images of the subsequent other components, and updating the Base address+offset size address of the component image in the corresponding component information; if the mirrored space address region is located in the last segment of the occupied address space in the system-defined component mirrored address space (as shown in fig. 9), there is no need to merge the recovered mirrored space address region with other free address regions. By judging whether the recovered mirror image space address area is required to be fused with other idle address areas, the problem that the module mirror image space is too scattered and discontinuous to cause the difficulty in allocating storage space when the module mirror image is updated due to the fact that the module system is used for identifying and adding new modules subsequently can be effectively avoided, and therefore the reliability of the system is improved.
Referring to fig. 10, a schematic flow chart of adjusting a master Boot image provided by the invention;
the adjusting the master Boot image according to the arrangement result specifically comprises:
According to the arrangement result, adjusting a jump mechanism when the master Boot image is loaded;
Updating a verification strategy when the master Boot image is loaded according to the arrangement result;
and updating the master control Boot image exception handling strategy according to the arrangement result.
Specifically, according to the arrangement result, the jump mechanism, the verification strategy and the master Boot image exception handling strategy during master Boot image loading are adjusted, the influence of the removed component on the master Boot can be reduced to the minimum, and the stability of the system is improved.
And adjusting a jump mechanism when the master control Boot image is loaded: the Boot image of the removed component needs to be ignored in the Boot image loading process of the main control module, and the process is actually realized by adding a corresponding jump mechanism when the Boot image of the main control module runs, for example: the Boot image of the main control module runs to a certain code, a protection site (the code address pointer is pushed onto a stack), jumps to the Boot image code address of the component to continue to execute, after execution is completed, the code address pointer which is pushed onto the stack before is fetched, and jumps to the address to continue to execute the subsequent program of the Boot image of the main control module. No matter how the loading of the Boot image containing the new component is completed, the modification of the jump mechanism when the main control Boot image is loaded is not bypassed.
Updating a verification strategy of master control Boot image loading: because the Boot image of the main control module to be loaded changes, in the loading process, the codes of each block should be subjected to sectional verification, and if necessary, an independent verification strategy is carried out to ensure the robustness of the system operation.
Updating a master control Boot image exception handling strategy: the exception handling is the last defense line of the Boot image of the main control module, and the exception handling in the Boot image loading process of the removed component should be omitted, so that false alarm is avoided.
Further, after a jump mechanism, a check strategy and a master Boot image exception handling strategy during master Boot image loading are adjusted, a second component information list is updated, the removed component does not need to be reset to take effect immediately by updating the second component information list, and the loading of the removed component is automatically skipped in the next power-on starting process of the system.
