[0006] Further, in step S2, the base station sends a sleep instruction to the weighing sensor module, and the steps of entering the sleep mode include: A1, the base station enters the sleep state, and sets the time to T0; A2, sets the base station operation status query time T1; A3, determines whether the motion query time T1 has arrived, if it has arrived, proceeds to step A4, otherwise, proceeds to step A1; A4, the base station wakes up the weighing module and performs information query.

[0007] Further, in step S2, the base station turns on the scanning channel and connects to the device via Bluetooth. The steps of waking up the weighing sensor module include: B1, the base station turns on the scanning channel and sets the time to T2; B2, detects whether the electronic scale has a detection instruction, and if so, proceeds to step B3, otherwise, the electronic scale is still in sleep state; B3, the base station connects to the electronic scale via Bluetooth to wake up the weighing sensor module.

[0008] Secondly, when the weighing module actively feeds back the base station, if there is commodity information arriving, the base station immediately exits the sleep mode. The following steps are included: C1, the main control sends a weighing command to the weighing module, and sets the reaction time to T3; C2, judging whether the base station gets weighing information feedback at time T3, if so, proceed to step C3, otherwise, proceed to step C1; C3, weighing information feedback is fed back to the base station via Bluetooth.

[0009] This solves the technical problem of reducing the complexity of manual weighing operations by transmitting information via Bluetooth on electronic scales in related technologies. BRIEF DESCRIPTION OF THE DRAWINGS
