Transmission tower on-line monitoring system

The invention provides a transmission tower on-line monitoring system and relates to the field of transmission tower on-line monitoring. The transmission tower on-line monitoring system solves the problems that an existing wired transmission tower on-line monitoring device is prone to being interfered by strong current signals on transmission lines and low in intellectualization degree. The transmission tower on-line monitoring system carries out multipoint data acquisition through N transmission tower monitoring units. Data comprise the tilt values, the microwave values, the wire tension values and the vibration values of transmission tower monitoring nodes. The tilt values, the microwave values, the wire tension values and the vibration values of the transmission tower monitoring nodes are transmitted to a transmission tower monitoring main unit in a wireless mode. The transmission tower monitoring main unit is used for monitoring the N transmission tower monitoring units, monitoring the temperature, the humidity, the wind speed, the wind direction, the rainfall, the air pressure and the sunlight illumination in the area where the transmission tower monitoring main unit is located, synthetically carrying out data processing and finally transmitting the processed data in a GPRS wireless communication mode to a monitoring center and mobile terminals capable of communicating with the monitoring center. The transmission tower on-line monitoring system is applicable to transmission tower on-line monitoring.
