The invention relates to a firmware upgrading technology of embedded equipment, and discloses an enhanced OTA (over the air) upgrading method based on the Internet of Things, which ensures the reliability of data, the stability of a data carrier and the recoverability after firmware upgrading fails in the OTA upgrading operation process of the embedded equipment. According to the OTA upgrading data processing method, when OTA upgrading data are received, data verification is conducted on each frame, Hash value verification is conducted on the whole data after the data are received, so that theintegrity and uniqueness of the data are guaranteed, and therefore the reliability of the data is improved; when the received data is written into the flash, the received data is not directly writteninto the flash, but is cached to a certain length through the flash writing interface and then written into the flash, so that the read-write frequency of the Flash can be reduced, and the operationstability of the Flash is e
