The invention discloses an electronic scale system with a wireless transmission function. The electronic scale system with the wireless transmission function is characterized by comprising a weighing unit, a cloud part and a mobile terminal, wherein the weighing unit serves as a scale body and comprises a main control panel, a wireless communication module, a display screen, a power source, buttons, a BIA detecting unit and a weighing sensor, the wireless communication module, the display screen, the power source, the buttons, the BIA detecting unit and the weighing sensor are respectively connected with the main control panel, an electrode plate is connected on the BIA detecting unit, a stress mechanism is connected on the weighing sensor, the cloud part comprises a cloud server and a wireless access point connected with the cloud server, the weighing unit is provided with an independent internet protocol (IP) which is used for being identified by the cloud part and the mobile terminal, the scale body can measure the weight, fat percentage, water percentage, muscle percentage, human-body bone content, visceral fat percentage or body mass index (BMI) value of a human body, the data can be transmitted by the wireless communication module, and the data are received by the wireless access point of the cloud part. Management software is arranged inside the cloud server, independent management files are established as each IP is independently matched with the scale body, and the data are stored. A terminal account can receive data of the scale body with the corresponding IP from the cloud part through a server.
