The utility model provides an online monitoring device of operating states of cantilevers of an overhead contact system. The online monitoring device, with the introduction of signal transmitters, signal receivers and a corresponding data processing unit, realizes precise positioning of structural components of the cantilevers, thereby realizing real-time monitoring of a running state anomaly of a corresponding cantilever. The online monitoring device has no electrical connection at two ends of an insulator of the cantilever, does not affect an insulating requirement of a cantilever system. The online monitoring system is small in size, and does not influence the operation of the cantilever system. In addition, a preferable scheme of taking advantage of an ultrasonic signal has the following prominent technical advantages: the ultrasonic wave is not sensitive to colors or illuminance; the ultrasonic wave is not sensitive to external light or an electromagnetic field and thus can be applied to severe environments such as a dark environment, an environment having dust, smog or strong electromagnetic interference, or a poisonous environment; an ultrasonic sensor is simple in structure, small in size, low in cost and simple and reliable in information processing, facilitating small side and integration of the online monitoring device.
