Method for improving transmission efficiency of low-precision floating-point number

Abstract

The invention discloses a method for improving the transmission efficiency of a low-precision floating-point number. Precision retention and classification are carried out on low-precision floating-point data collected by a sensor in the Internet of Things, and a method for dividing every three bits of collected decimal integers into one group is adopted; data with every three decimal integers as one group is converted into binary data and then converted into hexadecimal data, and the method has the advantages of being high in compression rate, few in redundant bits, small in storage amount, free of constraint of compression formats and the like, is particularly suitable for low-precision floating-point number transmission and can be widely applied to the fields of data processing of the Internet of Things and the like.

Description

Technical field [0001] The present invention relates to the field of Internet of Things, and more particularly to a method for improving low-precision floating point number transmission efficiency. Background technique [0002] Information transmission technology is widely used in various fields, and in the field of control engineering, data transmission has a vital role in communication. In the Internet of Things, due to wireless transmission relative to the wired transmission relative to external electromagnetic interference, how to quickly and efficiently transmit data, which is critical to the transmission of data of the Internet of Things. For example, monitor the information collected by the mobile robot, or detect the operational state of the drone. [0003] Publication No. CN111404907A's Chinese invention patent application discloses a data compression transmission method based on IEEE754 format, which is converted to 8-byte data based on IEEE754 bid-precision floating-po...
