Abstract

A railway condition monitoring device includes an acquirer structured to be attached to a railway vehicle bogie and acquire state information on one or more state of vibration, speed, acceleration, sound, reflected light, image, temperature, humidity, and a wheel diameter, a determiner structured to be attached to a bogie, perform a determination of a state of a track on which the bogie travels or a state of the bogie based on the state information acquired by the acquirer, and provide the determination result, a transmitter structured to be attached to the bogie and transmit the determination result to an outside of the bogie, and a power supplier structured to be attached to the bogie and supply power to the acquirer and the transmitter.

What is claimed is: 
     
         1 . A railway condition monitoring device, comprising:
 an acquirer structured to be attached to a railway vehicle bogie and acquire state information on one or more of vibration, velocity, acceleration, sound, reflected light, an image, temperature, humidity, and a wheel diameter;   a determiner structured to be attached to the bogie, perform a determination of a state of a track on which the bogie travels or a state of the bogie based on the state information acquired by the acquirer, and provide the determination result;   a transmitter structured to be attached to the bogie and transmit the determination result to an outside of the bogie; and   a power supplier structured to be attached to the bogie and supply power to the acquirer and the transmitter.   
     
     
         2 . The railway condition monitoring device according to  claim 1 , further comprising:
 a storage structured to temporarily store the information acquired by the acquirer.   
     
     
         3 . The railway condition monitoring device according to  claim 1 , further comprising:
 a position information acquirer structured to acquire position information on a position of the railway vehicle,   wherein the transmitter transmits the determination result to the outside of the bogie when the bogie is at a preset position based on the position information acquired by the position information acquirer.   
     
     
         4 . The railway condition monitoring device according to  claim 1 , wherein the transmitter transmits the determination result to the outside of the bogie when the determination result satisfies a predetermined condition. 
     
     
         5 . The railway condition monitoring device according to  claim 1 , wherein the power supplier includes a generator attached to the bogie and a battery charged by the generator, and
 the transmitter transmits the determination result to the outside of the bogie when a residual storage amount of the battery is greater than a preset level.   
     
     
         6 . The railway condition monitoring device according to  claim 1 , wherein the transmitter transmits the determination result to the outside of the bogie when a communication state with a communication partner is greater than the preset level. 
     
     
         7 . The railway condition monitoring device according to  claim 1 , wherein the transmitter is attached to a bogie frame, and the acquirer is attached to an unsprung part supported through a spring from the bogie frame. 
     
     
         8 . The railway condition monitoring device according to  claim 1 , wherein the determiner makes the determination using a learning model generated by using machine learning based on state information acquired in advance and the state of the track or the state of the bogie corresponding to the state information. 
     
     
         9 . The railway condition monitoring device according to  claim 8 , further comprising:
 a model generator structured to be attached to the bogie and generate the learning model,   wherein the model generator updates the learning model based on newly acquired state information and the state of the track or the state of the bogie corresponding to the state information.   
     
     
         10 . A railway vehicle bogie, comprising:
 an acquirer structured to acquires state information on one or more of vibration, speed, acceleration, sound, reflected light, an image, temperature, humidity, and a wheel diameter;   a determiner structured to make a determination of a state of a track on which the bogie travels or a state of the bogie based on the state information acquired by the acquirer and provide the determination result;   a transmitter structured to transmit the determination result to an outside of the bogie; and   a power supplier structured to supply power to the acquirer and the transmitter.   
     
     
         11 . A railway vehicle, comprising:
 a bogie;   an acquirer structured to be attached to the bogie and acquire state information on one or more of vibration, velocity, acceleration, sound, reflected light, an image, temperature, humidity, and a wheel diameter;   a determiner structured to be attached to the bogie, make a determination of a state of a track on which the bogie travels or a state of the bogie based on the state information acquired by the acquirer, and provide the determination result;   a transmitter structured to be attached to the bogie and transmit the determination result to an outside of the bogie; and   a power supplier structured to be attached to the bogie and supply power to the acquirer and the transmitter.
