Apparatus for verifying identity of operation rules of sensor device

摘要

The first server device 12 transmits the detection result data received from the sensor devices 11-1 to 11-n in response to a request from the analysis device 13. Terminal devices 15-1 to 15-n are connected to the sensor devices 11-1 to 11-n, respectively. The terminal devices 15-1 to 15-n transmit to the third server device 16 a message digest of rule data such as programs and parameters stored in the connected sensor devices 11-1 to 11-n every time a predetermined time elapses. The third server device 16 determines the consistency of the detection result data generated in each of the sensor devices 11-1 to 11-n based on the message digests received from the terminal devices 15-1 to 15-n. When using the detection result data received from the first server device 12, the analysis device 13 receives, from the third server device 16, the determination result data indicating the determination result of the consistency of the detection result data, The analysis is performed by using the detection result data having the data.
