Those skilled in the art can realize that the units and algorithm steps of each example described in conjunction with the embodiments disclosed herein can be implemented by electronic hardware, or a combination of computer software and electronic hardware. Whether these functions are performed in hardware or software may depend on the specific application and design constraints of the technical solution. Skilled artisans may use different methods for implementing the described functionality for each particular application, but such implementations should not be considered beyond the scope of the disclosed embodiments. The skilled person can clearly understand that, for the convenience and brevity of description, the specific working process of the above-described systems, devices and units can refer to the corresponding processes in the foregoing method embodiments, and details are not repeated here.

In the embodiments disclosed herein, the disclosed methods and products (including but not limited to apparatuses, devices, etc.) may be implemented in other ways. For example, the apparatus embodiments described above are only illustrative. For example, the division of the units may only be a logical function division. In actual implementation, there may be other division methods, for example, multiple units or components may be combined Either it can be integrated into another system, or some features can be omitted, or not implemented. In addition, the shown or discussed mutual coupling or direct coupling or communication connection may be through some interfaces, indirect coupling or communication connection of devices or units, and may be in electrical, mechanical or other forms. The units described as separate components may or may not be physically separated, and components displayed as units may or may not be physical units, that is, may be located in one place, or may be distributed to multiple network units. This embodiment may be implemented by selecting some or all of the units according to actual needs. In addition, each functional unit in the embodiment of the present disclosure may be integrated into one processing unit, or each unit may exist physically alone, or two or more units may be integrated into one unit.

The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to embodiments of the present disclosure. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code that contains one or more functions for implementing the specified logical function(s) executable instructions. In some alternative implementations, the functions noted in the blocks may occur out of the order noted in the figures. For example, two blocks in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. In the descriptions corresponding to the flowcharts and block diagrams in the accompanying drawings, operations or steps corresponding to different blocks may also occur in different sequences than those disclosed in the description, and sometimes there is no specific relationship between different operations or steps. order. For example, two consecutive operations or steps may, in fact, be performed substantially concurrently, or they may sometimes be performed in the reverse order, depending upon the functionality involved. Each block of the block diagrams and/or flowchart illustrations, and combinations of blocks in the block diagrams and/or flowchart illustrations, can be implemented in special purpose hardware-based systems that perform the specified functions or actions, or special purpose hardware implemented in combination with computer instructions.
