Abstract

The invention provides an APL-based signal edge acquisition method and system, and relates to the field of signal acquisition. The method is applied to an edge server, and comprises the following steps: acquiring a first signal data stream of machine equipment in an industrial automation scene; determining a working condition state based on the first signal data stream in combination with a context sensing method, and adjusting the working mode and sampling frequency of each sensor node according to the working condition state to obtain an adjusted operation instruction set; generating a system operation state report based on the first signal data stream and the adjusted operation instruction set to obtain a second signal data stream; constructing a trust framework of the industrial automation scene, and based on the trust framework, transmitting the second signal data stream to the central control system by adopting a standardized communication protocol; the standardized communication protocol is a communication protocol determined based on an adaptive protocol conversion gateway method. According to the technical scheme provided by the invention, the reliability of signal acquisition and processing is improved.
