COMMUNICATION SYSTEM

摘要

A communication system includes at least one sensor apparatus including at least one sensing element and a transmission circuit, and a microcomputer including a reception circuit and a differential calculator. The sensing element detects a sensor value indicating a physical quantity of a detection target, and the transmission circuit transmits, as a digital signal, a sensor signal including information indicative of the sensor value at a predetermined transmission cycle. The reception circuit receives the sensor signal through a signal line and updates last time sensor value with present time sensor value. The differential calculator calculates, at a predetermined calculation cycle, a time differential value by performing a time differential calculation to the updated using time information provided separate from the sensor value.

1. A communication system comprising:
at least one sensor apparatus including at least one sensing element and a transmission circuit, wherein the at least one sensing element detects a sensor value indicating a physical quantity of a detection target, and the transmission circuit transmits, as a digital signal, a sensor signal including information indicative of the sensor value at a predetermined transmission cycle; and a microcomputer including a reception circuit and a differential calculator, wherein the reception circuit receives the sensor signal transmitted from the transmission circuit of the at least one sensor apparatus through a signal line and updates the sensor value received at last time with the sensor value received at present time, and the differential calculator calculates, at a predetermined calculation cycle, a time differential value by performing a time differential calculation to the sensor value that is updated using time information provided separate from the sensor value.
