[0002] In modern society, mining lamp technology is developing rapidly. As an important safety equipment in coal mines, mines and other underground workplaces, the performance of mining lamps directly affects the life safety and work efficiency of miners.

[0003] In the field of mining lamp control technology, mining lamp control systems are generally developed based on the Android system to control the on and off of mining lamps and monitor the status of mining lamps. For mining lamp control systems, memory management is one of the key factors to ensure its stable operation. Once a memory leak occurs, the available memory may be reduced, affecting the performance and stability of the system.

[0004] At present, the traditional solution for memory management is mainly to monitor the garbage collection status through JVMTI (Java Virtual Machine Tool Interface) callbacks, and to monitor the callbacks created by the Activity according to the Activity life cycle. However, although this solution can monitor memory leaks, it cannot effectively deal with the memory leak body itself, resulting in poor results in solving the memory leak problem, and may result in misjudgment or missed judgment, resulting in untimely or unnecessary memory cleanup, thus making memory management inefficient.

[0055] The server 105 may be a server that provides various services, such as a background server that provides support for web pages displayed on the terminal devices 101 , 102 , and 103 .

[0056] It should be noted that the memory management method of the mining lamp control system provided in the embodiment of the present application is generally executed by a terminal device, and accordingly, the memory management device of the mining lamp control system is generally arranged in the terminal device.

[0057] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to the implementation requirements.

[0058] Continue to refer Figure 2 , shows a flow chart of an embodiment of a memory management method for a mining lamp control system according to the present application. The memory management method for a mining lamp control system comprises the following steps:

[0059] Step S201, obtaining life cycle change information of a preset component.

[0060] In this embodiment, the memory management method of the mining lamp control system is run on the electronic device (for example Figure 1 The terminal device shown in the figure can send or receive data through a wired connection or a wireless connection. It should be noted that the above wireless connection methods may include but are not limited to 3G / 4G / 5G connection, WiFi connection, Bluetooth connection, WiMAX connection, Zigbee connection, UWB (ultra wideband) connection, and other wireless connection methods currently known or to be developed in the future.

[0061] In this embodiment, in the mining lamp control system, Activity and Fragment are the core components for controlling and monitoring the mining lamp. The system monitors the status of the component (such as creation, destruction, etc.) in real time by registering the component's life cycle callback. Exemplarily, when the user interface of the mining lamp system (such as the mining lamp switch operation interface) is started, the system will call onCreate(), and when the interface is closed, it will call onDestroy(), and monitor memory usage through these callbacks. Of course, in addition to the Activity controlled by the mining lamp, the system can also monitor the life cycle of the Service running in the background (such as the monitoring service of the mining lamp status) to ensure that the background tasks will not cause memory leaks.

[0062] It should be noted that Activity is a basic component in Android applications, representing a screen or a page of an application. Each Activity is responsible for interacting with the user and displaying a user interface. Activity is the entry point for the application to interact with the user. It usually contains UI elements such as buttons, text boxes, pictures, etc.; Activity has a complete life cycle management. The system will call different methods in different states (such as start, pause, and destroy) so that developers can handle related events. For example, the onCreate() method is called when the Activity is created, and the onDestroy() method is called when the Activity is destroyed. Each Activity is usually an independent screen. When the user switches screens in the application, they usually switch to different Activities. Fragment is a more flexible and modular component, usually nested in Activity, used to create reusable UI modules. An Activity can contain multiple Fragments, which can run independently, be added or removed. Fragment provides more fine-grained control and can manage multiple Fragments in an Activity to achieve a dynamic and flexible user interface. For example, part of a screen can be managed by one Fragment and the other part by another Fragment. The life cycle of a Fragment is dependent on the life cycle of the Activity in which it resides. Similar to an Activity, a Fragment also has its own life cycle management methods, such as onCreateView() for creating the Fragment interface and onDestroyView() for destroying the Fragment interface. Fragments can be dynamically added, removed, or replaced while the Activity is running, making the application interface more flexible. It is very suitable for use on tablet devices to help manage complex layouts. A Fragment must be nested in an Activity to run, it cannot exist alone, and the life cycle of a Fragment is determined by the Activity in which it resides.

[0063] Step S202: determining a target component according to the lifecycle change information.

[0064] In this embodiment, the specific component that currently needs to be memory managed (for example, the currently running Activity) is determined based on the acquired lifecycle information. For example, if an Activity is about to be destroyed, the system can use it as the target component for subsequent memory management. The system can also dynamically determine whether to release the memory of certain components in advance based on the memory usage to optimize the overall memory utilization.

[0065] Step S203: Monitor the reference of the target component through a reference queue to obtain the reference status of the target component.

[0066] In this embodiment, a weak reference and a reference queue are created, and weak references are used to monitor whether the target component is processed by garbage collection (GC). Specifically, when the Activity is destroyed, weak references will not prevent it from being recycled by GC, and the system can monitor whether these weak references are cleared from the memory through the reference queue; different reference types (such as soft references or phantom references) can also be used for monitoring according to the type and priority of the target component to improve the flexibility of memory management.

[0067] Step S204, performing memory management according to the reference situation and the current garbage collection state to obtain a memory management result.

[0068] In this embodiment, the system decides whether to clean up the memory based on the situation in the reference queue and the current GC status. Specifically, if the target component has been recycled by GC, no cleanup is required; if it has not been recycled and the GC status is valid, the relevant memory is cleaned up. A custom garbage collection strategy can also be introduced to automatically start memory management when the system memory is tight, without relying on the system GC.

[0069] This application monitors the Activity life cycle and reference status in real time, handles memory leaks in a timely manner, and ensures the long-term stable operation of the mining lamp control system. Especially in complex operation scenarios, it can effectively reduce system freezes or crashes caused by memory leaks, thereby improving the memory management efficiency of the mining lamp control system developed based on the Android system.

[0070] In some optional implementations of this embodiment, the step of performing memory management according to the reference situation and the current garbage collection state to obtain a memory management result includes:

[0071] If the garbage collection state is a valid state, a memory leak result is generated according to the reference situation;

[0072] Execute a memory management process according to the memory leak result to obtain the memory management result;

[0073] If the garbage collection state is an invalid state, wait until the garbage collection state is a valid state.

[0074] In this embodiment, when the GC state of the mining lamp control system is valid, it checks whether the target component in the reference queue is recycled and generates a memory leak judgment result. If the mining lamp control Activity is not recycled during the effective GC period, the system determines that a memory leak has occurred; based on the memory leak situation, the system decides whether to perform a memory cleanup operation. If the system detects that the mining lamp control interface has not been recycled, the system will immediately release the relevant memory; when the GC state is invalid, the system will not perform memory management to avoid invalid cleanup. It can be optimized to actively trigger GC when the system memory is tight, thereby improving memory management efficiency.

[0075] Through intelligent judgment of GC status, this application enables the system to clean up memory at appropriate times, reduce unnecessary memory consumption in the mining lamp control system, and maintain efficient operation of the system, which is especially suitable for device environments with limited resources.

[0076] In some optional implementations of this embodiment, the preset component includes a registered interface carrier activity, the target component includes a current activity, and if the garbage collection state is a valid state, the step of generating a memory leak result according to the reference situation specifically includes:

[0077] Determine whether the current activity exists in the reference queue;

[0078] If the current activity exists, determining that there is no memory leak is taken as the memory leak result;

[0079] If the current activity does not exist, it is determined that a memory leak exists as the memory leak result.

[0080] In this embodiment, the system determines whether the target Activity has been recycled by checking the reference queue. For example, if the Activity of the mining lamp control interface has been recycled, the system determines that no memory leak has occurred; if the Activity does not exist in the reference queue, a memory leak is determined and a memory leak result is generated.

[0081] This application can accurately determine the status of the Activity, effectively prevent misjudgment or missed judgment, ensure that the mining lamp control system can accurately identify memory leaks, and improve the accuracy and reliability of memory management.

[0082] In some optional implementations of this embodiment, the step of executing the memory management process according to the memory leak result to obtain the memory management result specifically includes:

[0083] If there is no memory leak, no memory cleanup operation is performed;

[0084] If there is a memory leak, a memory cleanup operation is performed on the current activity and the fragments nested in the current activity.

[0085] In this embodiment, if it is confirmed that there is no memory leak in the Activity, the system will not perform unnecessary memory cleaning operations. If there is a memory leak, the system will clean up the target Activity and its related Fragment memory. For example, multiple Fragments are nested in the mining lamp system to display different status information. If these Fragments are not recycled by GC, the system will clean them together.

[0086] This application ensures that the system performs cleanup operations only when an actual memory leak is detected, avoiding frequent invalid memory releases and maintaining stable performance of the mining lamp control system.

[0087] In some optional implementations of this embodiment, the step of monitoring the reference of the target component through the reference queue to obtain the reference status of the target component specifically includes:

[0088] Create a weak reference and a reference list corresponding to the target component, and start the reference queue;

[0089] The weak references and the reference list are monitored according to the reference queue to obtain the reference status.

[0090] In this embodiment, a weak reference is created for the target Activity or Fragment, and a reference queue is enabled for monitoring. When the mining lamp control interface or its nested Fragment is started, the system creates a weak reference and adds it to the reference queue for real-time monitoring. For mining lamp status images that occupy a large amount of memory (such as real-time monitoring data), a similar weak reference mechanism can also be used for memory management.

[0091] This application uses weak references to avoid strong references to components, and the system can effectively prevent memory leaks, especially for objects that occupy a large amount of memory, which can significantly reduce the memory burden and improve the stability of the mining lamp control system.

[0092] In some optional implementations of this embodiment, after the steps of creating the weak reference and reference list corresponding to the target component and opening the reference queue, the following steps are further included:

[0093] Obtaining recycling information of the target component;

[0094] The reference queue is configured according to the recycling information.

[0095] In this embodiment, the system obtains information on whether the target Activity or other components have been recycled by GC, which is further used for memory management. The system detects whether the mining lamp control interface has been released from the memory to decide whether additional cleanup operations are required. According to the recycling status of the component, the system dynamically configures the reference queue. The reference queue can be configured according to the priority of different components (such as core control components are retained first, and non-core components are recycled first) to optimize the memory usage strategy.

[0096] This application obtains and adjusts the reference queue in real time, so that the system can dynamically adapt to the memory status and ensure that the mining lamp control system maintains the best memory management strategy during operation.

[0097] In some optional implementations of this embodiment, the step of configuring the reference queue according to the recycling information specifically includes:

[0098] If the target component is recycled, the weak reference is added to the reference queue;

[0099] If the target component has not been recycled, the weak reference is not added to the reference queue.

[0100] In this embodiment, if the target component has been recycled by GC, the system adds its weak reference to the reference queue to indicate that the object has been processed; if the target component has not been recycled, the system continues to monitor it.

[0101] This application ensures that the system will process related memory release operations only after GC completes recycling, avoiding invalid cleanup steps and further improving the operating efficiency of the mining lamp control system.

[0102] The embodiments of the present application can acquire and process relevant data based on artificial intelligence technology. Among them, artificial intelligence (AI) is the theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results.
