Temperature measuring cable based on USB interface and application system

The invention provides a temperature measuring cable based on a USB interface and an application system. The temperature measuring cable mainly comprises a sheath and a plurality of temperature sensors packaged in the sheath, wherein one end of the sheath is closed, and the other end is provided with a USB interface; and the plurality of temperature sensors are arranged at intervals along the length direction of the sheath, and the temperature sensors are connected through a wire and then electrically connected with the USB interface finally. The application system comprises the temperature measuring cable based on the USB interface and electronic equipment connected with the temperature measuring cable through a USB. The electronic equipment is pre-stored with identification information and corresponding position information of each temperature sensor of the temperature measuring cable, thereby being convenient for querying position information of each temperature monitoring point according to the identifica
