PROBLEM TO BE SOLVED: To provide a component measuring device and a component measuring system of cultivated crops which are capable of collecting measurement data of a predetermined component amount of cultivated crops in an easily usable mode for data management or data analysis of a farm field.SOLUTION: A component measuring system (1) comprises component measuring devices (10A,10B) having: a component sensor which measures a predetermined component amount contained in a cultivated crop an identification information acquisition part which acquires identification information identifying cultivated crops in a farm field individually or by a group a control part which transmits a component amount measured by the component sensor and identification information acquired by the identification information acquisition part in an associated manner. Furthermore, the system comprises: a server device (30) which stores information transmitted from the component measuring devices (10A,10B) and display devices (40A,40B) which display information of a component amount of cultivated crops in the farm field by individual cultivated crop or by a group of cultivated crops.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】栽培作物の所定の成分量の計測データを、圃場のデータ管理またはデータ分析に利用しやすい形態で収集することのできる栽培作物の成分計測装置および成分計測システムを提供する。【解決手段】この成分計測しシステム(1)は、栽培作物に含まれる所定の成分量を計測する成分センサと、圃場の栽培作物を個々に或いは一群ごとに識別する識別情報を取得する識別情報取得部と、成分センサにより計測された成分量と、識別情報取得部により取得された識別情報とを対応づけて送信する制御部と、を有する成分計測装置(10A,10B)を備えている。さらに、成分計測装置(10A,10B)から送信された情報を記憶するサーバ装置(30)と、圃場の栽培作物の成分量の情報を、個々の栽培作物ごと、或いは、一群の栽培作物ごとに表示する表示装置(40A,40B)とを備えている。【選択図】図1
