Method and system for resetting, restarting and locking power of Bluetooth sound system

The invention discloses a method and a system for resetting, restarting and locking power of a Bluetooth sound system, which are used for performing power failure, restarting and locking power during a product test, and the method comprises the following steps: resetting a Bluetooth sound entering a test mode, and clearing all pairing information; during resetting, the main control module transmits a power locking instruction to the power locking module; and after receiving the power locking instruction, the power locking module locks power supply of the power supply within a specified time until the power supply stably supplies power. A power locking module is arranged in a system of the Bluetooth sound equipment, and a low-cost power locking MCU chip is arranged in the power locking module, so that resetting can be performed on a main control module of the system and an SOC unit for power locking, power supply of a power supply is locked, power supply stability is kept, and power locking is quitted after re
