Embodiment Construction
[0072] like figure 1 As shown, the data transmission method of an embodiment of the present invention includes the following steps:
[0073] Step S201: Establishing a cache step: creating a piece of shared memory as a data cache in a memory independent of the application system;
[0074] Step S203: data acquisition step: when the application system is started or running, the data cache is mounted, and the data cache is accessed to obtain the service data to be transmitted.
[0075] The step of establishing the cache in this embodiment is preferably performed based on an embedded Linux operating system.
[0076] The data cache in this implementation is an external cache independent of the application system. The size of the shared memory used as a data cache depends on the hardware configuration. On the premise of sufficient resources, the larger the shared memory, the more data it can hold, and the higher the reliability of the data. Since this shared memory does not depend...
