Long data processing method based on far infrared data transmission system

Abstract

The invention provides a long data processing method based on a far infrared data transmission system, which is applied to the far infrared data transmission system at least comprising an infrared data transmitting device and an infrared data receiving device. The long data processing method specifically comprises the following steps: presetting a first data length threshold value and a transmission suspension time threshold value based on hardware characteristics limited by a received data length of an infrared data receiving head; the method comprises the following steps: segmenting first data based on to-be-sent first data, a preset data length first threshold and a transmission suspension time threshold, and sending the first data to an infrared data receiving head by an infrared tube; according to the long data processing method based on the far infrared data transmission system, the defects of hardware of the infrared receiving head are overcome through a software method, the long data processing efficiency is improved, and the long data processing efficiency is improved. The method has the advantages of high expansibility, simplicity in implementation and high engineering practicability.

Description

technical field [0001] The invention relates to the field of infrared signal data processing, in particular to a long data processing method based on a far-infrared data transmission system. Background technique [0002] In the prior art, an infrared receiving head is generally used to collect far-infrared data. The infrared receiving head is a device that integrates receiving, amplifying and demodulating. The internal IC has already completed the demodulation, and the output is a digital signal. [0003] At present, most infrared receiving tubes, especially pulsed infrared receiving heads, due to their own performance, in the receiving process, when the number of consecutively received bytes reaches more than 150-200, the number of bytes received will be higher than the number of bytes sent. The number of bytes is short, or abnormal phenomena such as bit errors. [0004] For example, the common infrared receiving head IRM-3638T, when this type of infrared receiving tube re...

Problems solved by technology

[0004] For example, the common infrared receiving head IRM-3638T, when the infrared receiving tube of this type receives the data transmitted by far infrared, when the transmission character exceeds 200 bytes, the reception of the infrared receiving tube becomes unstable, namely The length of the received data is shorter than the length of the data we send through far infrared, and the received data also has bit errors

[0005] IRM-3638T products using infrared receivers, such as smart meters with infrared receivers, in the process of production inspection, in order to improve production efficiency, factory parameters need to be set through a private protocol of 250 bytes or more , but under the existing technical conditions, due to the hardware performance defect of the infrared receiving head itself, at least twice the parameter instructions are required to set the factory parameters, and the production efficiency is not high
