Description of the Related Art Conventionally, a bearing typified by an axle of a railway vehicle requires measures such as stopping the operation of the vehicle when an abnormality occurs in the bearing. In order to avoid such an unexpected stoppage of operation during traveling, it is necessary to constantly monitor the state of the bearing such as whether or not the bearing is abnormal. Conventionally, the state of the bearing has been monitored by attaching a thermo label that changes color with temperature rise to the axle box and allowing a worker to visually check the color change of the thermo label when the vehicle is stopped.

This belt conveyor is often installed in steep mountainous areas with a total length of several kilometers. Conventionally, the inspection of the bearings used for this belt conveyor has been performed by a worker who regularly patrols on foot.

Since the sensor means is provided in each bearing of a structure such as a railway vehicle, it is possible to detect information about the temperature, load, vibration, rotational speed, etc. of the bearing. Then, the detection signal is once transmitted to the relay means, and then transmitted from the relay means to the monitor means. By thus passing the relay means, when the transmission line is wired, it is not necessary to lay a signal line directly to the monitor means for each sensor means, so the cost and labor for laying the signal line is reduced. In addition, even in the case of an abnormality such as a disconnection, the restoration process is simplified. When the transmission path is wireless, a transmitter with low power consumption and low output can be used for signal transmission, and resource saving and cost reduction can be achieved. Then, by monitoring the monitor means, information from each bearing can be easily and quickly grasped collectively. The monitor means may be provided with an abnormality display means for performing a predetermined process on the received signal and for displaying the fact when it is determined that there is an abnormality. Thus, the bearing abnormality can be detected even while the vehicle is traveling.

ことができる。Belt conveyors are often used not only in ordinary civil engineering sites but also in mines and the like. Especially when it is used in a mine, it is installed over a long distance on a steep sloping land or in a tunnel, but according to this embodiment, the transmission signal V
Since a, Vb, and Vc are transmitted in a relay manner between the adjacent belt conveyors 21, signal transmission can be reliably performed. Further, the relays 8a, 8b, 8c may have a small output, and the relays can be downsized, and the connection and replacement work of the conveyors 21 can be easily performed. The transmission paths of the transmission signals Va, Vb, Vc are not limited to wireless and may be wired. In this case, wiring can be performed along the power cord for driving the conveyor.
