Abstract

The invention relates to a data processing system in industrial wireless sensor network. The invention comprises a data converging unit, a data repeater and a data acquisition unit. The invention alsorelates to a data processing method, which comprises the following steps: the data converging unit sends a meter-reading command frame to the data repeater; the data repeater sends the meter-readingcommand frame to the data acquisition unit; after the data acquisition unit receives the meter-reading command frame, the data acquisition unit sends a fixed time request frame and applies for the fixed time thereof; after receiving the fixed time request frame, the data repeater determines a superframe time through setting the synchronizing time parameter and the active time parameter, broadcasts a time synchronizing frame, adjusts each time slot of superframe, and returns to the confirmed frame; the data acquisition unit determines the fixed time in the time synchronizing frame with reset synchronizing time parameters and active time parameters, and sends the data frame formed by the collected data within the fixed time; the data repeater sends the data frame to the data converging unit. Accordingly, the data processing system and the processing method provided by the invention are cheap and process data precisely.

Description

technical field [0001] The invention relates to the electronic field and the industrial field, in particular to a data processing system and processing method for time synchronization of an industrial wireless sensor network information table. Background technique [0002] With the development of the times, industrial automation is becoming more and more common, and at the same time, the consumption of various public supply meters such as water, electricity, and gas in the industrial environment is also increasing. Therefore, there are more and more meter reading methods for counting the information of these meters. The existing traditional and most common meter reading method is mainly manual meter reading. Therefore, this manual meter reading method has poor flexibility, inaccurate meter reading, and very low efficiency, high time and economic costs, and a large workload for data aggregation. [0003] The intelligent chemical factory workshops that have emerged have also ...
