The invention provides an integrated monitoring system based on a power tower. The integrated monitoring system comprises a power tower network, a monitoring module, a pre-processing module, a communication and positioning module and a monitoring data center platform, wherein the monitoring module, the pre-processing module, the communication and positioning module and the monitoring data center platform are arranged on the power tower. The monitoring platform comprises an evaluation module, a warning alarm module and a display module. The monitoring module is an optical fiber sensor arranged on the power tower. The pre-processing module is used to carry out threshold filtering on each parameter collected by the optical fiber sensor. The communication and positioning module is a Beidou positioning device arranged on the power tower to provide communication and positioning functions. The warning alarm module is used to give out warning or alarm according to a received digital signal from the evaluation module. The display module is used to display the power tower network in a panoramic map and highlight the power tower which sends valid information. The integrated monitoring system provided by the invention relies on the mature management mode of the power industry and the existing tower network, which greatly reduces the initial construction cost and the subsequent operation and maintenance cost.
