The invention discloses a portable wireless static strain measuring system. The portable wireless static strain measuring system comprises a handheld wireless receiver and a plurality of wireless static strain sensors; the sensors are used for collecting strain information at a measuring point and wirelessly transmit the processed information to the handheld wireless receiver; and the receiver isresponsible for organizing and establishing a wireless sensor network and collecting, displaying and storing strain data. The portable wireless static strain measuring system has the advantages that by adopting a new chip technology, a low power consumption strategy and portable design, the characteristics of high resolution, a wide range, portability and a long battery service life of strain detection are realized, and the arrangement of the sensors is flexible, the number is adjustable, only short wires need to connect the strain measuring point and the sensors, and the receiver can displayand store information without relying on an external computer; and the measuring efficiency is improved, the labor intensity is reduced, and the system is suitable for applying to distributed strain detection occasions such as health monitoring of a port mechanical metal structure.
