Problems solved by technology

[0004] Although the existing Zigbee technology is very mature, when it transmits data with small values ​​and low precision, the data transmission volume under the fixed byte number is low, and the servo cycle is relatively low under the fixed distance and the number of floating point numbers. Insufficient high

Embodiment 1

[0042] 1. Data compression transmission:

[0043] 1) Collect N data, where N is a positive integer.

[0044] For example: The collected data are -169.224, 12.3014, 36.489, 53.2159, -462.364, -45.36, -99.3705, -365.24.

[0045] 2) Divide the N data into X groups according to specific conditions (reserved precision and sign bit processing need to be considered), and X is a positive integer.

[0046] Specifically, the N data are divided into two groups, then X=2, the first group is marked as a, and the second group is marked as b, as follows:

[0047] data a 1

[0048] 3) Initialize group number mark value i=1 and checksum C 0 =0.

[0049] 4) Take the first group of data, reserve the corresponding precision and process the sign for each data as needed, and then assemble it into a decimal integer D not exceeding 15 digits 1 (Default first time i=1).

[0050] As the following group 1 data:

[0051] data a 1

[0052] where a 1 is a negative value, and ...

Abstract

The invention discloses a data compression transmission method based on IEEE754 format. This method is to group the collected data first, and then assemble them into a decimal number of no more than 15 digits according to certain rules, and then convert it into 8-byte data according to IEEE754 double-precision floating-point format, and add data header and data tail to it. and the checksum; after receiving the data, the receiver first checks whether the data is complete and verifies whether it is correct. If the data is complete and correct, first filter the data header, data tail and checksum and then split the data , and then converted into decimal integers according to the IEEE754 double-precision floating-point format, and the resulting decimal integers are separated according to the assembly format before compression, and then the precision and sign are processed to obtain the data before compression. The method of the invention can remarkably improve the transmission efficiency when transmitting data with small value and low precision, and can autonomously clear wrong data and incomplete data.

Description

technical field [0001] The invention relates to a data compression transmission method based on the IEEE754 format, and belongs to the technical field of data compression processing. Background technique [0002] Information technology is widely used in various fields, and data transmission plays a vital role in the field of communication methods. Zigbee technology is a short-distance, low-complexity, low-power, low-speed, low-cost two-way wireless communication technology. Transmission, also suitable for typical applications with periodic data, intermittent data and data transmission with low latency. [0003] The invention patent with the publication number CN 105634499 A discloses a data conversion method based on new short floating-point data, including: determining the transformation form of data conversion and the transformation algorithm adopted, and the transformation form of data conversion includes but Not limited to compression, decompression, storage and transm...
