To provide a remote confirmation system capable of remotely confirming a state of a mobile body that is suitable for use of LPWA communication having restrictions on communication frequency and transmission data capacity.SOLUTION: A remote confirmation system includes: a wireless communication device provided in a mobile body; a server for receiving mobile body information indicating a state of the mobile body from the wireless communication device via a first communication network; and a communication terminal for receiving notification information based on the mobile body information from the server via a second communication network. When setting a first mode, the wireless communication device wirelessly transmits the mobile body information in a first cycle that does not exceed a predetermined transmission frequency. When setting a second mode, the wireless communication device wirelessly transmits the mobile body information including abnormality information when a detection unit detects the abnormality to set a third mode from the second mode. During a period of setting the third mode, the wireless communication device wirelessly transmits the mobile body information in a second cycle that may exceed a predetermined transmission frequency.SELECTED DRAWING: Figure 6
【課題】通信回数、送信データ容量に制約があるLPWA通信を用いる場合に適した、移動体の状態を遠隔確認することができる遠隔確認システムを提供する。【解決手段】本発明に係る遠隔確認システムは、移動体に備わる無線通信装置と、無線通信装置から第1通信網を介して移動体の状態を示す移動体情報を受信するサーバと、サーバから第2通信網を介して移動体情報に基く通知情報を受信する通信端末とを含む。無線通信装置は、第1モードを設定する場合、移動体情報を所定の送信回数を超えない第1周期で無線送信し、第2モードを設定する場合、検知部が異常を検知したときに異常情報を含む移動体情報を無線送信して第2モードから第3モードに設定し、第3モードを設定している期間に移動体情報を所定の送信回数を超える可能性がある第2周期で無線送信する。【選択図】図6
