The utility model discloses a stress detection device which comprises an omega-shaped elastic structure, a strain gauge sensor is arranged on the outer surface of the elastic structure, and a fiber grating sensor is arranged on the inner surface of the elastic structure. Stress data generated in the operation process of the wind turbine generator can be monitored in real time through the strain gauge sensor and the fiber grating sensor on the omega-shaped elastic structure, and due to the fact that the two types of sensors have the anti-electromagnetic interference capacity, the stress data can be monitored in real time. The detection device is not interfered by electromagnetic signals in the process of monitoring the stress data of the wind turbine generator, so that the accuracy of the stress monitoring result of the wind turbine generator can be remarkably improved. And meanwhile, compared with a low-frequency sensor, the two types of sensors are low in manufacturing cost, so that the cost input required f
