[0054] As can be seen from the above description, the embodiment of the present utility model provides a railway catenary pole inclination monitoring system. By installing the monitoring slave station on the catenary pole, the change of the pole inclination is monitored in real time, and the pole inclination situation is reported to the operation unit through the wireless transmission mode, so that the operation personnel can observe the inclination situation of all poles in real time, and timely process the poles with excessive inclination to avoid accidents such as the interruption of railway operation or casualties caused by the pole collapse. Compared with the original manual measurement method, it reduces the manpower and material resources. The low-power wireless transmission mode not only saves the communication cable, but also reduces the power consumption. Only relying on the battery and solar power generation can meet the normal operation of the slave station, so the power cable is also saved at the same time. Since the real-time monitoring improves the timeliness of the data, the fault is exposed in the early stage, and the occurrence of accidents is reduced.
