Abstract: A detection system and a wind driven generator. The detection system includes: a plurality of passive wireless sensors respectively provided at the corresponding positions to be detected, which are used for obtaining detection signals of the positions to be detected; and a leaky coaxial cable provided along the position to be detected, wherein the leaky coaxial cable can emit electromagnetic waves to drive the plurality of passive wireless sensors, and can receive the detection signal sent by the passive wireless sensors. The detection system can save installation space, as well as reduce maintenance costs since there is no need to replace a battery regularly, and when conducting multi-point measurements, costs are reduced and the number of passive wireless sensors that the system can configure is increased.
