摘要： A wireless communication device, a wireless information collection system, and a wireless communication method are provided. The wireless communication device is configured to wirelessly transmit predetermined information provided therein to its master device in a predetermined transmission cycle and executes the wireless transmission in a time slot of itself according to a predetermined time division multiple access scheme together with one or more wireless slave devices including at least a reference wireless slave device. First unrelated transmission information including reference transmission time information wirelessly transmitted from the reference wireless slave device to its master device in the predetermined time division multiple access scheme is acquired during the wireless transmission and a time counted by an internal timer unit is corrected based on an amount of correction calculated from an acquisition time of the first unrelated transmission information and the reference transmission time information included in the first unrelated transmission information.

摘要： A controller performs a control operation associated with a control target. The controller includes a communication interface that electrically connects at least one function unit to the controller through a data transmission path, a writing unit that writes an observation value obtained through the function unit into a database, and a delay obtaining unit that obtains a delay time taken from when a signal indicating an observation value is input into the function unit to when data representing the observation value becomes usable in the controller, and stores information indicating the obtained delay time.

摘要： A controller includes a control operation unit that cyclically performs a control operation for controlling a control target, a data generator that generates data showing a chronological change in a value associated with a control target, and an analyzer that analyzes the data and outputs an analysis result in a predetermined analysis target period. The analysis target period includes a plurality of sections. The data generator sequentially outputs section data showing a chronological change in a value for each of the plurality of sections in the analysis target period. The analyzer analyzes the sequentially output section data for each section. When an analysis of section data for a section in the analysis target period shows a predefined result, the analyzer eliminates an analysis of section data for one or more sections in the analysis target period that are subsequent to the section for which the analysis shows the predefined result.
