Abstract
A power tool system includes a power tool; a battery pack detachably connected to the power tool, and a cloud server capable of wirelessly communicating with the power tool. The power tool includes a wireless communication unit configured to establish a wireless communication link with an external device and a file storage unit coupled to the wireless communication unit and configured to store content data in a preset data structure. The preset data structure includes a packet header configured for information transmission, a packet tail including a check bit, and a data packet body including a data length, a data type, a packet serial number, data content and an electronic serial number. A simple and efficient method of deduplicating data is used to release the memory space of the memory and improve data transmission efficiency.
