Problems solved by technology

Distributed multi-scene sensor groups can obtain data information in different scenarios. Multi-scene sensor groups require nearly simultaneous data transmission. Data cross-transmission destroys the "time redundancy" feature of the data group, that is, time sparsity, thus reducing compression ratio

Abstract

The invention provides a sensor array common-channel data compression and transmission method and device. The device comprises a sensor array, a sensor array driving and storage address distributor, a multi-channel data register, a data capture compression and transmission module and a data decompression module. By utilizing the sparse characteristic of data in a register unit in the time dimension, a problem of low compression efficiency caused by heterogeneous data of multiple scenes is avoided on the premise of ensuring that a multi-channel sensor collects data at the same time, and the characteristic of high compression efficiency of continuous data collection of a single sensor in a single target scene is inherited; the same data compression rate as that of a single sensor in a single scene can be kept when high-time-resolution data transmission is carried out under multiple sensors and multiple scenes.

Description

technical field [0001] The invention belongs to the technical field of data compression and transmission, and in particular relates to a sensor array common-channel data compression method and compression transmission equipment. Background technique [0002] With the continuous development of sensor arrays, the scale of target data acquired by humans is increasing, which is mainly reflected in: 1. The data scale of a single sensor is constantly increasing, such as the sampling time resolution, spatial resolution, spectral resolution, The magnetic field resolution and other dimensional feature resolutions continue to improve; 2. From a single sensor to a sensor network, humans begin to deploy sensor networks for target scenarios to achieve multi-point high-precision data collection in space. These new changes have led to the continuous increase of data bandwidth, but the data transmission channel is limited by hardware conditions and will not increase indefinitely. Although n...
