To provide a communication system that ensures simultaneity of a plurality of sensor values transmitted via a plurality of communication paths with a simple configuration.SOLUTION: A first receiving unit 501 of a microcomputer 70 has a plurality of signal acquisition units 61A, 61B and one transmission trigger signal generator 63B. The plurality of signal acquisition units 61A and 61B are connected to sensor elements 31A and 31B of a corresponding sensor device 301 via individual communication paths 41A and 41B, and acquire sensor values S1A and S1B transmitted via the communication paths 41A and 41B when the communication paths 41A and 41B are ready for transmission. The one transmission trigger signal generator 63B generates a common transmission trigger signal Trc1 so that the plurality of communication paths 41A and 41B become ready for transmission simultaneously. In the first receiving unit 501, the plurality of signal acquisition units 61A and 61B can simultaneously acquire the plurality of sensor values S1A and S1B by the common transmission trigger signal Trc1.SELECTED DRAWING: Figure 1 【課題】複数の通信路を経由して送信される複数のセンサ値の同時性を簡易な構成で確保する通信システムを提供する。【解決手段】マイコン７０の第１受信部５０１は、複数の信号取得部６１Ａ、６１Ｂと、一つの伝送トリガ信号生成部６３Ｂと、を有する。複数の信号取得部６１Ａ、６１Ｂは、対応するセンサ装置３０１のセンサ素子３１Ａ、３１Ｂと個別の通信路４１Ａ、４１Ｂを介して接続されており、通信路４１Ａ、４１Ｂが伝送可能な状態になったとき、通信路４１Ａ、４１Ｂを経由して送信されたセンサ値Ｓ１Ａ、Ｓ１Ｂを取得する。一つの伝送トリガ信号生成部６３Ｂは、複数の通信路４１Ａ、４１Ｂを同時に伝送可能な状態にするように共通の伝送トリガ信号Ｔｒｃ１を生成する。第１受信部５０１において、複数の信号取得部６１Ａ、６１Ｂは、共通の伝送トリガ信号Ｔｒｃ１により、複数のセンサ値Ｓ１Ａ、Ｓ１Ｂを同時に取得可能である。【選択図】図１
