[0038] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0039] The following is a reference appendix. Figure 1-6 This application describes a subroutine resource quota management method, apparatus, and system for smart meters according to embodiments of the present application.

[0040] Figure 1 This is a flowchart of a subroutine resource quota management method for a smart meter according to the first embodiment of this application.

[0041] It should be noted that the subroutine resource quota management method for smart meters in this embodiment is applied to the host computer. By writing subroutines for each function in the host computer, the written subroutines are sent to the smart meter to realize the multi-functionality of the smart meter.

[0042] like Figure 1 As shown, the subroutine resource quota management method for this smart meter may include the following steps:

[0043] S110, Obtain the executable subroutine, wherein the executable subroutine is written using a preset resource quota during development.

[0044] Specifically, in the host computer, developers write code according to preset resource quotas when developing subroutines. After the code is written, it is compiled and the compiled executable subroutines are submitted to the administrator. The administrator can view the resource quotas occupied by each executable subroutine through the resource management tool in the host computer.

[0045] It should be noted that administrators can set preset resource quotas according to actual needs. When developing executable subroutines, developers should use the preset resource quota as the upper limit and ensure that the code does not exceed the preset resource quota.

[0046] S120, determine the target resource quota, and update the executable subroutine according to the target resource quota, wherein the resource quota occupied by the updated executable subroutine is less than or equal to the target resource quota.

[0047] Specifically, after obtaining the executable subroutine, the relationship between the resource quota occupied by the executable subroutine and the target resource quota is compared. If the resource quota occupied by the executable subroutine is greater than the target resource quota, the executable subroutine is updated so that the resource quota occupied by the updated executable subroutine is less than or equal to the target resource quota.

[0048] For example, the target resource quota can be the fixed resource quota allocated to each executable subroutine in the smart meter. After the developers write the executable subroutine based on the preset resource quota, if the resource quota occupied by the executable subroutine is greater than the target resource quota, the executable subroutine needs to be adjusted so that the resource quota occupied by the adjusted executable subroutine is less than or equal to the target resource quota. This allows multiple executable subroutines to work together as more and more subroutines are installed in the smart meter.

[0049] For example, the default memory allocation for the executable subroutine corresponding to the alarm function in a smart meter is set to 30MB. The developer writes an executable subroutine of 25MB based on this 30MB. In practical applications, assuming the target resource allocation is 20MB (meaning the user-specified alarm function occupies 20MB of memory on the smart meter), the executable subroutine can be adjusted and updated so that the updated 25MB subroutine occupies less than or equal to 20MB of memory on the smart meter. This means that writing the subroutine within the default resource allocation limits subsequent updates, ensuring a smaller adjustment range and thus guaranteeing the reliability and integrity of the subroutine's functionality.

[0050] S130, the updated executable subroutine is sent to the smart meter so that the smart meter can load and run the updated executable subroutine according to the target resource quota.

[0051] Specifically, after updating the executable subroutine according to the target resource quota, the updated executable subroutine is sent to the smart meter, which then loads and runs the updated executable subroutine upon receiving it.

[0052] In some embodiments, Figure 2 This is a flowchart of step S120 in the subroutine resource quota management method for a smart meter according to the first embodiment of this application. Figure 2 As shown, updating an executable subroutine may include the following steps:

[0053] S210, determine the code compilation file for the executable subroutine.

[0054] Specifically, the developer writes the subroutine source code in the host computer, compiles it to generate assembly code, and converts the assembly code into machine instructions to generate the target binary file, which is the compiled code file of the executable subroutine.

[0055] S220 modifies the code compilation file to reduce the resource quota used by the executable subroutine.

[0056] Specifically, the target binary file is modified to reduce the resource quota occupied by the executable subroutine, so that the resource quota occupied by the modified executable subroutine is less than or equal to the target quota.

[0057] As one possible implementation, when the target resource quota is greater than or equal to the preset resource quota, the executable subroutine is directly sent to the smart meter.

[0058] It is understandable that when the target resource quota is greater than or equal to the preset resource quota, if the resource quota occupied by the executable subroutine written according to the preset resource quota is less than or equal to the preset resource quota, that is, if the resource quota occupied by the executable subroutine is less than or equal to the target resource quota, then there is no need to update the executable subroutine, and the executable subroutine can be directly sent to the smart meter.

[0059] As an example, before distributing the executable subroutine to the smart meter, the process also includes signing the executable subroutine.

[0060] Specifically, when the target resource quota is less than the preset resource quota, the executable subroutine is modified and updated, and the updated executable subroutine is signed; when the target resource quota is greater than or equal to the preset minimum resource quota, the executable subroutine is directly signed. After signing the executable subroutine, the signed executable subroutine is sent to the smart meter.

[0061] It should be noted that an executable subroutine is in a development state before being signed, and in a signed state after being signed. An executable subroutine in the signed state cannot be modified.

[0062] In some embodiments, before determining the target resource quota, the method further includes responding to a subroutine loading request from the smart meter.

[0063] Understandably, upon receiving a subroutine loading request from a smart meter, the target resource quota is determined, and the executable subroutine is updated and loaded according to the target resource quota.

[0064] Figure 3 This is a flowchart of a subroutine resource quota management method for a smart meter according to a second embodiment of this application.

[0065] It should be noted that the subroutine resource quota management method for smart meters in this embodiment is applied to smart meters. Smart meters are advanced metering devices that collect, analyze, and manage electrical energy information data based on modern communication, computer, and measurement technologies. In addition to the basic electricity metering function of traditional meters, smart meters also possess intelligent functions such as bidirectional multi-rate metering, user-end control, bidirectional data communication with multiple data transmission modes, and anti-theft features to adapt to smart grids and the use of new energy sources. In this embodiment, the smart meter receives and runs executable subroutines from a host computer, thus realizing the multi-functionality of the smart meter.

[0066] like Figure 3 As shown, the subroutine resource quota management method for this smart meter may include the following steps:

[0067] S310, send a subroutine loading request to the host computer. The subroutine loading request is used to instruct the host computer to obtain the executable subroutine, determine the target resource quota, and update the executable subroutine according to the target resource quota so that the resource quota occupied by the updated executable subroutine is less than or equal to the target resource quota. The executable subroutine is written using the preset resource quota during development.

[0068] For example, the functions that need to be implemented in the smart meter can be selected according to actual needs. Based on the subroutines corresponding to the required functions, the target resource quotas corresponding to each subroutine are determined, and a subroutine loading request is sent to the host computer. The administrator determines the relationship between the target resource quota of the executable subroutine and the preset resource quota based on the subroutine request sent by the host computer. When the target resource quota is less than the preset resource quota, the executable subroutine is updated so that the resource quota corresponding to the updated executable subroutine is less than or equal to the target resource quota.

[0069] For example, the subroutines on a smart meter are used to implement various functions, such as automatic measurement, billing, and alarm functions. Each subroutine corresponds to a different resource quota after it is written.

[0070] S320 receives the updated executable subroutine from the host computer and loads and runs the updated executable subroutine according to the target resource quota.

[0071] Specifically, when the resource quota corresponding to the subroutine is less than or equal to the target resource quota, the updated executable subroutine sent by the host computer is received, and the updated executable subroutine is loaded and run based on the target resource quota.

[0072] As one possible implementation, when the target resource quota is greater than or equal to the preset resource quota, it also includes: receiving an executable subroutine sent by the host computer.

[0073] It is understandable that when the target resource quota is greater than or equal to the preset resource quota, it means that when the resource quota occupied by the executable subroutine is less than or equal to the target resource quota, the host computer will not modify or update the executable subroutine, but will directly send the executable subroutine to the smart meter.

[0074] It should be noted that after the host computer sends the signed executable subroutine to the smart meter, the status of the executable subroutine changes from the signed state to the installed state, and the status of the executable subroutine being run by the subroutine loader in the smart meter changes from the installed state to the running state.

[0075] To implement the above embodiments, this application also proposes a computer-readable storage medium storing a subroutine resource quota management program for a smart meter. When the subroutine resource quota management program for a smart meter is executed by a processor, it implements the subroutine resource quota management method for a smart meter according to any of the above embodiments of this application.

[0076] To implement the above embodiments, this application also proposes a host computer, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements the subroutine resource quota management method for smart meters described in the first embodiment of this application.

[0077] To implement the above embodiments, this application also proposes a smart meter, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements the subroutine resource quota management method for the smart meter described in the second embodiment of this application.

[0078] Corresponding to the subroutine resource quota management method for smart meters provided in the first embodiment above, an embodiment of this application also provides a subroutine resource quota management device for smart meters. Since the subroutine resource quota management device for smart meters provided in this embodiment corresponds to the subroutine resource quota management method for smart meters provided in the above embodiments, it will not be described in detail in this embodiment. Figure 4 This is a schematic diagram of the subroutine resource quota management device for a smart meter according to the first embodiment of this application.

[0081] Optionally, the update module is specifically used to: determine the code compilation file of the executable subroutine; and modify the code compilation file to reduce the resource quota occupied by the executable subroutine.

[0082] As an example, when the target resource quota is greater than or equal to the preset resource quota, the distribution module is specifically used to: directly distribute the executable subroutine to the smart meter.

[0083] As one possible implementation, before the executable subroutine is sent to the smart meter, the update module is specifically used to: sign the executable subroutine.

[0084] Optionally, before determining the target resource quota, the update module is specifically used to: respond to a subroutine loading request from a smart meter.

Figure 5 As shown, the subroutine resource quota management device 500 of the smart meter may include: a sending module 501, a receiving module 502, and a loading module 503.

[0087] Specifically, the sending module 501 is used to send a subroutine loading request to the host computer, wherein the subroutine loading request is used to instruct the host computer to obtain an executable subroutine, determine the target resource quota, and update the executable subroutine according to the target resource quota, wherein the resource quota occupied by the updated executable subroutine is less than or equal to the target resource quota, and the executable subroutine is written using a preset resource quota during development; the receiving module 502 is used to receive the updated executable subroutine sent by the host computer; and the loading module 503 is used to load and run the updated executable subroutine according to the target resource quota.

[0088] As one possible implementation, when the target resource quota is greater than or equal to the preset resource quota, the receiving module is specifically used to receive the executable subroutine sent by the host computer.

[0089] To implement the above embodiments, this application also proposes a subroutine resource quota management system for smart meters.
