PROBLEM TO BE SOLVED: To provide a state monitoring device of a railroad vehicle that is configured to reduce the number of radio receivers in the whole of a train set and reduce costs of and installation work burdens for a carriage monitoring device, while keeping stable communication quality.SOLUTION: A state monitoring device 10, which is used for a train set 1 in which cars 11-14 comprising car bodies 21-24 and a pair of carriages 31F-34R arranged at both end parts in a longitudinal direction of the car bodies are connected, comprises: sensors 41F-44R, installed in the carriages respectively, which detect state information about equipment installed in the carriages; radio transmitters 51F-54R that transmit sensor signals including the detected state information; and at least one radio receiver that receives the sensor signals transmitted from the radio transmitters. The radio receiver, arranged between a carriage near a second car of a pair of first carriages and a carriage near a first car of a pair of second carriages, which includes first radio receivers 61F and 61R which receive first state information about the first carriage near the second car and second state information about the second carriage near the first car.SELECTED DRAWING: Figure 1 【課題】安定した通信品質を保ちながら、列車編成全体として無線受信機の数を削減し、台車監視装置のコスト及び設置作業負担を軽減する状態監視装置を提供する。【解決手段】車体２１〜２４と、車体の長手方向の両端部に配置された一対の台車３１Ｆ〜３４Ｒとを備えた車両１１〜１４が連結された列車編成１に用いられる状態監視装置１０であって、各台車に設けられ、台車に設けられた機器の状態情報を検知するセンサ４１Ｆ〜４４Ｒと、検知された状態情報を含むセンサ信号を送信する無線送信機５１Ｆ〜５４Ｒと、無線送信機から送信されたセンサ信号を受信する少なくとも１つの無線受信機と、を備える。無線受信機は、一対の第１台車のうち第２車両側の台車と、一対の第２台車のうち第１車両側の台車間に配置され、第２車両側第１台車の第１状態情報と、第１車両側第２台車の第２状態情報とを受信する第１無線受信機６１Ｆ、６１Ｒを含む。【選択図】図１
