The invention discloses an absolute grating ruler multi-track encoding method. In order to solve problems, such as the accumulative error of incremental encoding and the hardware complexity of absolute encoding, etc., in the micro-nano machining measurement process, the invention adopts an absolute encoding method based on p-element M-sequence pseudo-random codes suitable for single track and multiple tracks. The encoding method is suitable for a straight line absolute position encoder, and a disk absolute angle encoder, locating can be performed at any time, and the boot back-to-zero operation does not needed. Moreover, an incremental encoding strip is provided, so measurement accuracy can be improved by suing the phase segmentation method. The encoding method is an absolute position encoding method has advantages of easy generation, replication and processing, large encoding capacity, low decoding cost and macro-micro composite performance. The encoding method comprises ordinary single-track binary M-sequence absolute grating ruler straight-line encoding, a M-sequence disk encoder, code expanding method multi-code-channel pseudo-random code straight-line encoding and code expanding method p-element M-sequence pseudo-random codes, and the maximum encoding method is obtained by combing the above the encoding methods.

The embodiment of the invention discloses coding method, device and equipment, and a storage medium, and belongs to the field of natural language processing. The coding method comprises the steps: obtaining a target paragraph and a context statement of the target paragraph, and inputting the target paragraph and the context statement into a memory coding model; and obtaining an original vector setand a memory vector set in an input layer, obtaining a first target statement matrix of the original vector set in a memory layer according to the original vector set and the memory vector set, obtaining a paragraph vector of a target paragraph according to the first target statement matrix in an output layer, and carrying out processing based on the paragraph vector. And each statement is codedby taking the target paragraph as a unit, so that the coding speed is increased. Moreover, in the coding process, the target paragraph itself is considered; the context statement of the target paragraph is also considered; the paragraph vector for accurately describing the target paragraph can be obtained according to the association relationship between the statement in the target paragraph and the context statement; and the coding accuracy is improved.

The invention discloses a pre-coding method and a pre-coding device for multi-point coordinated transmission.
