The invention discloses a main/standby power supply circuit, a communication device, equipment and a computer readable storage medium. The main and standby power supply circuit comprises a system power supply, a standby power supply, a charging unit, a detection unit and a main control unit, the charging unit and the detection unit are connected with the system power supply, the main control unit is connected with the detection unit, and the system power supply supplies power to the charging unit, the detection unit and an external functional unit; the standby power supply independently supplies power to the functional unit or supplies power to the functional unit together with the system power supply; the charging unit provides charging power for the standby power supply according to the system power supply; the detection unit detects the power supply state of the system power supply; and the main control unit determines that the system power supply independently supplies power to the functional unit or supplies power to the functional unit together with the standby power supply according to the power supply state. According to the invention, an effective and stable main and standby power supply scheme is realized, normal operation of other equipment functions of the vehicle-mounted communication device when the power supply of the whole vehicle system is abnormal is ensured, and the vehicle use experience of a user is enhanced.

    本发明公开了一种主备供电电路、通讯装置、设备及计算机可读存储介质。其中,该主备供电电路包括系统电源和备用电源、与系统电源连接的充电单元和检测单元、以及与检测单元连接的主控单元,其中:系统电源向充电单元、检测单元以及外部的功能单元供电;备用电源单独地向功能单元供电,或与系统电源共同向功能单元供电;充电单元根据系统电源向备用电源提供充电电能;检测单元检测系统电源的供电状态;主控单元根据供电状态确定由系统电源单独地向功能单元供电,或与备用电源共同向功能单元供电。本发明实现了一种有效且稳定的主备电供电方案,确保了车载通讯装置在整车系统电源异常时其它设备功能能够正常运行,增强了用户的用车体验。
