System for quality control and operations management
First Claim
1. A quality control system for commodities, comprising:
- at least one sensor node which is attached to a commodity, which has at least one sensor, and which transmits data collected by the sensor; and
a management server which stores information obtained from the sensor node, wherein the sensor node changes a state thereof from a sleep state to an operative state responding to one of a first interruption caused by a clock signal and a second interruption caused by a trigger resulting from an external change, and wherein a period of the clock signal is made different between before and after the second interruption is made.

Abstract
A conventional problem with commodity quality control in a traceability system is inability to appropriately change settings for quality measurement according to environmental changes. The present invention provides a system which solves the problem and realizes real-time quality control with low power consumption. In the system for commodity quality control and operations management according to the present invention, an IC tag and a sensor node for quality measurement are attached to each commodity. The system has a mechanism for detecting either one or both of a change in the location of the commodity and a change in the work performed for the commodity. The sensor node for quality measurement can appropriately change settings for quality measurement according to a change in the location of the commodity or in the work performed for the commodity.
