The master device transmits the fixed-period signal through the signal line regularly at a transmission period, and transmits start time information indicating a transmission start time at which transmission of the fixed-period signal is started and transmission period information indicating the transmission period for the fixed-period signal through the data bus. The slave device counts a number of times the fixed-period signal is received and calculates, as a current time in the master device, a transmission time at which the master device transmits the fixed-period signal based on the number of times the fixed-period signal is received. The slave device corrects the time to the calculated current time in the master device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Time synchronization system, master device, slave device, and program","description":"A time synchronization system includes a master and slave devices connected to each other via a data bus and a signal line dedicated to transmission of a fixed-period signal.
