Wind energy measuring system

The utility model discloses a wind energy measuring system, which relates to the technical field of wind energy monitoring and comprises a captive balloon, a cable, a tension sensor, an A/D (analog/digital) converter chip, an ATK-IMU901 angle sensor, an ARM (advanced RISC machine) processor, a communication module, a power module and ground processing equipment. The tension sensor is arranged at one end, close to the captive balloon, of the mooring rope; the A/D converter chip can convert an analog signal output by the tension sensor into a digital signal; the ATK-IMU901 angle sensor is used for being arranged at the end, close to the captive balloon, of the mooring rope. The ARM processor is used for being in communication connection with the A/D converter chip and the ATK-IMU901 angle sensor, and the ARM processor can receive information output by the A/D converter chip and the ATK-IMU901 angle sensor; the communication module is used for being in communication connection with the ARM processor and ground p
