Description

Energy-saving data slicing method and networking system based on time-sensitive network Technical Field The invention relates to the technical field of data processing, in particular to an energy-saving data slicing method and a networking system based on a time-sensitive network. Background Emerging technologies such as industrial internet, autonomous car networking, and intelligent health systems are all important Time Sensitive Network (TSN) applications. Time sensitive control loops have begun to be implemented in industrial automation equipment to cope with stringent delay constraints. With the development of industry 4.0, intelligent manufacturing is a goal for leading the development of the next generation of industrial technology, the scale of the industrial internet is larger and larger, the generation equipment used in the industrial manufacturing is controlled by a network system controlled by a computer, sensors and actuators integrated in the network are also more and more, and the systems form physical control systems, wherein the physical control systems are key components of the intelligent manufacturing, the normal operation of the physical control systems needs the support of the corresponding network, and new challenges of how to manage time-sensitive congestion in the industrial internet are quite remarkable. Many of these physical control systems have high demands on the transmission speed of the network, e.g. the motion control of the cooperative robot is highly time-sensitive, requiring a low-latency transmission network for its operation. To address the requirements for real-time communications in the above applications, the IEEE time sensitive network task group developed a set of standards called IEEE 802.1Qbv, which includes a time aware shaper (TIME AWARE SHAPER, TAS) that relies on synchronization time periods and feature gate time periods for high priority pre-congestion. TAS aims at providing instant packet services, and in order to cope with dynamic network scenarios, it is considered to dynamically allocate network resources using a variety of reassembly mechanisms. In particular, for a given boundary of network capacity, it is desirable to maximize the traffic flow that is allowed in the network. In the last decades, in order to maximize network resource allocation, the method of maximizing network utility has become a common strategy. At present, when energy-saving data are acquired and transmitted, as the energy-saving field end relates to a plurality of data acquisition nodes, the acquisition frequency (period) of the energy-saving data and the size of a data block for acquiring the data once by each node are different, the data acquisition, transmission and processing efficiency can be greatly influenced, and the high-speed low-delay operation of a transmission network is not facilitated. Disclosure of Invention The invention provides an energy-saving data slicing method and a networking system based on a time-sensitive network, which solve the problem of low data acquisition, transmission and processing efficiency in the prior art. The technical scheme of the invention is realized as follows: According to an aspect of the present invention, there is provided a time-sensitive network-based energy-saving data slicing method, including the steps of: determining a standard time slice according to the acquisition period of each acquisition node; Determining a standard data block according to the size of the data block acquired by each acquisition node; Slicing the time slices with the acquisition period being greater than the standard time slices, and accumulating the time slices with the acquisition period being less than the standard time slices, so that the acquisition period of the time slices after slicing and accumulating is consistent with the acquisition period of the standard time slices; Slicing the data blocks with occupied memories larger than the standard data blocks, and accumulating the data blocks with occupied memories smaller than the standard data blocks, so that the occupied memories of the data blocks after slicing and accumulating are consistent with the occupied memories of the standard data blocks. The invention mainly starts from two dimensions of time and data, and respectively starts from the thought of calculating a standard time slice and a standard data block, so that the time slice segmentation of energy-saving data of different industrial field acquisition nodes in the time dimension and the data block size splitting in the data block dimension are realized, and meanwhile, the time slice and data block recombination technology of a time sensitive network in a data link layer is utilized, thereby realizing the efficient transmission of the energy-saving data, further achieving the purposes of simplifying the acquisition process of monitoring data, shortening the time of data processing and analysis and further optimizing the energy saving of t
