1. A data acquisition method applied to an industrial device and comprising:
generating a first operation parameter according to a data acquisition protocol, wherein the data acquisition protocol comprises a device access sub protocol and a data format sub protocol;
performing data processing on the first operation parameter to obtain a second operation parameter;
uploading the second operation parameter to a server system; and
receiving a control instruction from the server system;
wherein the control instruction is generated by the server system according to the second operation parameter, the control instruction is configured to control operation state of the industrial device;
encapsulating compressed or encoded data element to obtain an encapsulated data element according to a network protocol, detecting communication state between the industrial device and the server system, caching the encapsulated data element in a local database of the industrial device if the communication state is unstable, and uploading the encapsulated data element to the server system if the communication state is stable;
establishing communication with the server system, wherein the data format sub protocol is configured to indicate format of the first operation parameter;
verifying the first operation parameter according to the data format sub protocol;
determining whether the format of the first operation parameter is consistent with the format indicated by the data format sub protocol; and
analyzing the first operation parameter according to the data format sub protocol, and extracting data element in the first operation parameter.
