Low-latency redundancy communication protocol based on improved PRP protocol

The invention provides a low-latency redundancy communication protocol based on an improved PRP protocol, which is compatible with a PRP protocol standard of IEC 62439-3-2016 and works on a link layer. The dual-redundancy port is connected to an upper-layer protocol through a link redundancy entity and is transparent to the upper-layer protocol; the network end nodes are provided with dual-redundancy or triple-redundancy network ports which are respectively connected to networks which are mutually independent and have the same topological structure, and the networks work in parallel; and the same IP address and MAC address are set for each network port to which the end node supporting the PRP protocol belongs. The method is characterized in that a redundancy discarding algorithm is changed into a mode of directly uploading a first communication frame to an application layer; taking {a source IP address, a source MAC address and a frame sequence number} as a judgment condition of a redundant frame; the method comprises the following steps: writing a single-network-port node IP address in a network into a configuration file in advance in a node by adopting a pre-configuration file mode; and network port link on-off frequency statistics, super receiving window statistics, frame number discontinuous statistics and redundant frame asynchronous frequency statistics are added.

An absolute grating position calculation method based on an adaptive error correction sliding window

PendingCN122670722AAvoid direct reference toavoid position
This invention belongs to the field of high-precision position detection technology, and particularly relates to an absolute grating position calculation method based on an adaptive error-correcting sliding window. A photodetector array, in conjunction with an error-correcting sliding window, collects photoelectric signals of symbols, converting them into a symbol amplitude sequence. Abnormal erased symbols are identified through symbol confidence levels. If erased symbols are found, the window length is gradually expanded, and the process is repeated iteratively until a qualified target error-correcting sliding window is obtained. After removing erased symbols within the target error-correcting sliding window, grating position calculation is performed. After detecting a single acquisition position, the process is repeated for subsequent acquisition positions until the task is completed. This invention relies on adaptive iteration of the window to achieve signal error correction, reducing the interference of bad symbols on the calculation results and effectively improving the overall performance of grating position detection.
