Zusammenfassung:PROBLEM TO BE SOLVED: To provide a monitoring system and a monitoring device which can establish a time synchronization between devices at an early stage, in a configuration collecting measurement results concerning a solar cell panel by the respective devices.SOLUTION: A monitoring system has a single or a plurality of monitoring devices performing a measurement concerning a solar cell panel, and a collection device. Each of the monitoring devices transmits a time synchronization request to the collection device, which receives the time synchronization request transmitted from each of the monitoring devices and transmits a time synchronization response including a current time to each of the monitoring devices. Each of the monitoring devices receives the time synchronization response transmitted from the collection device, sets a current time of the self device on the basis of the current time included in the time synchronization response, and transmits the time synchronization request to the collection device at a timing based on identification information of the self device.SELECTED DRAWING: Figure 7 【課題】各装置による太陽電池パネルに関する計測結果を収集する構成において、各装置間での時刻同期を早期に確立することのできる監視システムおよび監視装置を提供する。【解決手段】監視システムは、太陽電池パネルに関する計測を行う1または複数の監視装置と、収集装置とを備え、各前記監視装置は、時刻同期要求を前記収集装置へ送信し、前記収集装置は、前記各監視装置から送信された前記時刻同期要求を受信して、現在時刻を含む時刻同期応答を前記各監視装置へ送信し、前記各監視装置は、前記収集装置から送信された前記時刻同期応答を受信して、前記時刻同期応答に含まれる前記現在時刻に基づいて自己の現在時刻を設定し、前記各監視装置は、自己の識別情報に基づくタイミングで、前記時刻同期要求を前記収集装置へ送信する。【選択図】図7
