To provide an on-vehicle monitoring system that can improve reading accuracy of an RF tag in a vehicle.SOLUTION: An on-vehicle monitor system 1 comprises a first reader units 10A to a third reader unit 10C that radiate a radio wave radiation range 12 in a car compartment 201 with a radio wave, conduct wireless communication with an RF tag 51 held by a monitoring object 50 in the radio wave radiation range 12, using an RFID, and receive monitoring object information based on the RF tag 51. Out of the first reader units 10A to the third reader unit 10C, the second reader unit 10B serving as a slave with respect to the first reader unit 10A is arranged in a radio wave radiation range 12 of the first reader unit 10A, and is configured to start in accordance with the radio wave radiated from the first reader unit 10A. The second reader unit 10B is configured to, when receiving the monitoring object information, transmit the monitoring object information to the first reader unit 10A.SELECTED DRAWING: Figure 3 【課題】車両内のＲＦタグの読み取り精度を向上させることができる車載監視システムを提供する。【解決手段】車載監視システム１は、車室２０１内の電波放射範囲１２に電波を放射し、電波放射範囲１２内の監視対象物５０が保持するＲＦタグ５１との間でＲＦＩＤを利用して無線通信を行い、ＲＦタグ５１に基づいた監視対象物情報を受信する第１リーダ部１０Ａ〜第３リーダ部１０Ｃを備える。第１リーダ部１０Ａ〜第３リーダ部１０Ｃのうち、第１リーダ部１０Ａに対して従となる第２リーダ部１０Ｂは、第１リーダ部１０Ａの電波放射範囲１２に配置され、第１リーダ部１０Ａから放射された電波に応じて起動する。第２リーダ部１０Ｂは、監視対象物情報を受信した場合、監視対象物情報を第１リーダ部１０Ａに向けて送信する。【選択図】図３
