A data acquisition method using an ultra-low power consumption industrial wireless data acquisition system

Abstract

The invention discloses a data acquisition method applied to an industrial wireless data acquisition system with ultra-low power consumption. The industrial wireless data acquisition system comprises a wireless data acquisition unit, a wireless cluster head unit, a wireless alarm unit, a redundancy cluster head unit, a wireless aggregation unit and a redundancy aggregation unit, wherein the wireless data acquisition unit is used for transmitting data to the wireless aggregation unit through the wireless cluster head unit, and transmitting an alarm value to the wireless aggregation unit through the wireless alarm unit if the data abnormality occurs, and the wireless aggregation unit is used for transmitting the data to an upper computer. According to the data acquisition method provided by the invention, the conflict can be reduced by using a dual-band radio frequency identification module, therefore the system is more stable; furthermore, parts of external units are powered by an I / O (Input / Output) pin of a single-chip microcomputer and are controlled to match with the sleep and operation of the units by the on and off of the I / O pin, therefore the power consumption of the system can be reduced.

Description

technical field [0001] The invention belongs to the technical field of data acquisition, and in particular relates to a data acquisition method using an ultra-low power consumption industrial wireless data acquisition system. Background technique [0002] Industrial data acquisition is the information link between on-site automation control equipment and management. Establishing and perfecting an automatic data acquisition system has become the focus of information construction in manufacturing industrial enterprises. [0003] At present, many enterprises usually use wireless sensors to collect data in various aspects of data collection, and judge whether the data is abnormal through the host computer, without real-time alarm function; there is no backup mechanism, which makes the data collection system lack of stability. [0004] In addition, due to the limited installation conditions of industrial data acquisition equipment, power lines cannot be used everywhere for power ...

Problems solved by technology

[0003] At present, many enterprises usually use wireless sensors to collect data in all aspects of data collection. The upper computer judges whether the data is abnormal, and does not have real-time alarm function; there is no backup mechanism, which makes the data collection system lack of stability.

[0004] In addition, due to the limited installation conditions of industrial data acquisition equipment, power lines cannot be used everywhere for power supply, so data acquisition equipment is usually powered by batteries, and the limitations of installation conditions will make it very difficult to replace batteries, so this is a problem for data The power consumption of acquisition equipment puts forward higher requirements
