Adaptive network data coding-decoding device

Abstract

The invention discloses an adaptive network data coding-decoding device, which is characterized in that a main shaft of the adaptive network data coding-decoding device passes through a base in the axial direction and can rotate relative to the base, a magnetic source body and a grating disk are arranged at the inner end of the main shaft, the magnetic source body is located at the axis of the main shaft, and the grating disk is coaxially connected with the main shaft; an optical signal emitted by a light emitting element passes through the grating disk and is then received by a light collector; a magnetic collector is arranged opposite to the magnetic source body and used for receiving a magnetic signal emitted by the magnetic source body, the light collector and the magnetic collector are connected with a circuit board, the light emitting element is connected to a first power supply through a first controller, and the first controller controls the connection and disconnection betweenthe light emitting element and the first power supply; and the magnetic source body is composed of an electromagnet device, the electromagnet device comprises an electromagnet core and a coil, the coil is wound on the electromagnet core and connected to a second power supply through a second controller, and the second controller controls the connection and disconnection between the coil and the second power supply, thereby being capable of eliminating a problem of signal errors caused by inertia errors generated by rotation of the main shaft.

Description

technical field [0001] The invention relates to a codec, in particular to an adaptive network data codec. Background technique [0002] A codec, also known as an encoder, is a device that compiles and converts signals (such as bit streams) or data into signal forms that can be used for communication, transmission, and storage. The encoder converts angular displacement or linear displacement into an electrical signal, the former is called a code disc, and the latter is called a yardstick. A rotary encoder is a rotary sensor that converts angular displacement into a series of digital pulses, such as an encoder disclosed in application publication number CN105157734A. The main problem of this type of encoder is that the inertial error generated by the spindle rotation cannot be eliminated, and the existence of this inertial error directly leads to the error of the signal collected and output by the collector. Contents of the invention [0003] The object of the present inve...
