There are provided an automatic inspection system and an automatic inspection method capable of suppressing power consumption of a measurement device. A measurement device includes a sensor unitthat measures an inspection target, a parameter management unitthat determines a predetermined parameter set for the sensor unit based on parameter determination information received from a data collection device, and a measurement data generation unitthat generates measurement data by analyzing data obtained by the sensor unit measuring the inspection target by using the predetermined parameter. The data collection device includes a parameter determination information generation unitthat generates parameter determination information, and a measurement data acquisition unitthat specifies the parameter determination information for the measurement device, requests the measurement device to acquire the measurement data, and stores the measurement data acquired from the measurement device.

Automated inspection system and automated inspection method including a data collection device that generates exposure parameter determination information

An inspection target reading device includes a wireless slave station that performs communication via a wireless network, a measurement unit that measures a state of an inspection target, and an analysis unit that generates measurement data, and transmits the measurement data from the wireless slave station via the wireless network. An automatic inspection system includes a wireless master station that communicates with each inspection target reading device via the wireless network, a data acquisition unit that acquires the measurement data from each inspection target reading device through a wireless master station, a data storage unit that stores the measurement data, a determination condition storage unit that stores determination conditions related to the measurement data, and an inspection unit that outputs predetermined measurement data selected from the stored measurement data and a predetermined determination condition corresponding to the predetermined measurement data among the stored determination conditions in association with each other.

Automatic inspection system and method for controlling automatic inspection system

A reading device includes wireless slave devices that communicate via a multihop wireless network, a measuring unit that measures the state of an inspection target to generate measurement data, a measurement data analysis unit, and a failure cause analysis unit that analyzes a failure cause when the analysis of the failure cause analysis unit fails. The reading device transmits the measurement data to the data collecting device by associating the measurement data with failure cause information. The data collecting device includes a wireless master device, a measurement data acquisition unit that acquires measurement data from each reading device, a recording unit that records the measurement data when the measurement data is not associated with failure cause information, and a retry control unit that retries data acquisition according to the type of the failure cause when the measurement data is associated with the failure cause information.

Automatic inspection system, inspection target reading device for automatic inspection system, and control method for automatic inspection system

A data collection apparatus collecting data from a terminal device connected through a communication path, comprising a schedule managing unit determining a schedule transmitting a data acquisition request to the terminal device according to managed timing data, a transmission amount adjusting unit adjusting a transmission amount of the data acquisition request, and a collected data managing unit managing the data collected from the terminal device, in which the schedule managing unit manages a start point time that is a time at which a data collection from each terminal device starts, a collection period that is an interval of the data collection from each terminal device, a retransmission interval that is a time until the data acquisition request is retransmitted when the data collection from the terminal device fails, and a retransmission number that is the number of times to retransmit the data acquisition request as the timing data.

Data collection apparatus and data collection method

An automatic inspection system, which includes a wireless slave device having a reading device that acquires a physical quantity to be inspected and a wireless master device that receives measurement data of the physical quantity from the wireless slave device, is provided with a data collection device that collects the measurement data from the wireless slave device via the wireless master device in a constant cycle and detects a time zone in which the measurement data is non-acquirable by the reading device based on a result of the collection. The wireless master device performs control to avoid the wireless slave device from re-acquisition of the measurement data in the non-acquirable time zone based on a result of the detection of the non-acquirable time zone.

Automatic inspection system and automatic inspection method

A ring network system is a ring network system in which a plurality of nodes including a blocking node that blocks transfer of a predetermined frame are connected in a ring shape, and when, any one of the plurality of nodes detects a change in a link state with an adjacent node, the node detecting the change transmits a collision frame for inquiring a collision of a blocking node to a current blocking node, and in accordance with a response from the current blocking node, a determination is made which of the nodes is to be a new blocking node, and in a case where the link state with the adjacent node has a higher priority level of blocking than a link state between the current blocking nodes, the node having detected the change transmits a collision frame for inquiring a collision of the blocking node.
