Field of the Invention The present invention relates to a hot-swap circuit, and more particularly to a circuit suitable for providing a hot-swap function in a mobile device to replace a battery. [Prior Art] Traditional mobile devices (such as laptops, personal digital assistants, 1 or walkmans) use a single battery to provide power. Therefore, in the process of the user turning the mobile device on, the device often encounters insufficient power in the device 10, causing the user to interrupt the current work and shut down the mobile device (turn 〇 ff). , then replace a new battery, in order to restart the mobile device to use. The other 4-knife mobile device does not have the function of a Warm swap battery. It is assembled in the mobile device 15 with a main battery and a spare battery to work when the user turns the mobile device on. During the process, when the mobile device encounters a battery power shortage, the user must also interrupt the current action, and operate the mobile device into a suspend mode, then replace a new battery, and then exit the pause mode. After (suspend mode), you can restart the mobile device. 2. As can be seen from the above, 'the known mobile device cannot achieve the function of directly hot swapping and replacing the battery when the system is powered on or not suspend'. Therefore, when the battery power is insufficient in the mobile device, use The user must interrupt the job and enter the suspend mode (suspend m〇de) 'or the line 5 1307991 thus causing the device to shut down (turn 0ff); then; after the updated battery is inconvenient And there is a need to improve. SUMMARY OF THE INVENTION The main purpose of the present invention is to provide a circuit for providing a hot-swappable battery function for a bamboo moving device, which can provide a user's mobile device at booting (10) η or non-suspended (sincere state) Immediately hot swap new battery. \ ^ ' 10 15 20 To achieve the above purpose, the mobile device of the present invention provides a hot-swappable battery - the circuit includes a main battery, a backup battery, a battery selection list a plurality of intrusion control units and a battery lock switch, wherein the battery lock switch is transferred to the main battery and an accidental control unit for locking the main battery on the mobile device; The battery selection unit is electrically connected to the battery 2 and the backup battery; the embedded control unit is electrically connected to the battery selection early π, and when the mobile device is powered on, monitors the battery lock switch=state, when the battery is locked When the switch locks the main battery, the control battery selection unit switches to supply power from the main battery to the mobile device, and when the battery lock switch has unlocked the main battery, the battery selection unit is controlled In turn, the battery is powered by the backup battery. The above-mentioned mobile device provides a hot-swappable battery function. The battery selection unit selects at least one of the main battery and the backup battery, and provides power to the mobile device. In the circuit that provides the hot-swappable battery function in the above-mentioned bamboo moving device, it also includes a DC power converter, which is electrically connected to the main battery and the backup battery to turn off a stable DC power. The above-mentioned mobile device provides a function of hot-swapping battery function. When the mobile device provides power for the backup battery, the human control unit: the system controls the parameters or preset parameters, and closes the basic functions of the component. In the circuit for providing the hot-swappable battery function in the above mobile device, when the binding device uses the backup battery to provide the power #, the new main battery can be directly replaced in the non-off state. The hot-swappable battery is provided in the above mobile device. In the function circuit, when the mobile device uses the backup battery to provide power, it can be in the non-sleep state: [Embodiment] 15 is a circuit system diagram for providing a hot-swappable battery function of the mobile device of the present invention, which is mainly composed of a main battery-backup battery 匕'-battery selection unit 3, An embedded control unit 4, a charging unit 5, a DC power converter 6, and a battery lock switch 7. The battery lock switch 7 is used to lock the main battery i in the mobile device, and the battery The lock 7 is coupled to the embedded control unit 4 to enable the embedded control unit 4 to sense the state in which the battery lock switch 7 is locked or released. The selection unit 3 is electrically connected to the main battery. With the backup battery 2. The input control; the early connection is connected to the battery selection unit 3 and the system component power supply 1 power-saving switch ··· etc. Among them, the system component power switch and the province 20 1307991 according to system parameters or presets The control of the parameter value controls the components of the two-knife system to achieve the purpose of power saving. For example, the function of reducing the brightness of the display device or the function of turning off the output of the taste meter, etc. 5 10 15 is electrically connected to the battery selection unit 3, the main battery 1 and the damage battery 2 by the lightning 兀5 system. The DC power converter 6 is electrically connected to the main battery! and the backup battery 2' is supplied to the mobile device with output-stable DC money. In this embodiment, the mobile device is a handheld wireless tablet PC). In order to achieve the purpose of hot-swapping the battery, the mobile device is provided with a primary battery and a backup battery 2, wherein the backup battery 2 has the same output power value as the main battery i, and the capacity backup battery is mainly used. The battery's - half' is based on the battery's charge and discharge characteristics, so that the backup battery can withstand the system load and provide the same power for the mobile device. In this embodiment, when the external power source is charged or the mobile device is activated, the preset priority in the charging unit 5 is to charge the backup battery 2. In addition, the invention can also modify the preset priority of the charging unit 5 by command according to the actual needs of the user, and correct it to preferentially charge the main battery. The battery selection unit 3 is electrically connected to the main battery pack and the backup battery 2, and the battery selection unit 3 is configured to switch one of the main battery pack or the backup battery 2 to supply power to the mobile device. The embedded control unit 4 internally presets a processing program for monitoring the power state of the main battery pack and the backup battery 2 when the mobile device is turned on, and detecting the state of the battery lock switch 7. 2 is a flow chart showing the use of the hot-swappable battery function of the mobile device according to the present invention, and referring to the system architecture diagram shown in FIG. 1. First, when the action is 1307991, as described above, the present invention is applied to the mobile device. The circuit for providing hot-swappable power is 'by locking the battery lock switch to the state of locking or releasing the battery control switch, and the towel is automatically switched to be replaced by the main battery. When the mobile device is turned on (_(10)) or not temporarily t (in the state of yelling, it is directly hot-swapped (4), please (4) replace the new battery*' without affecting the original action. The above embodiment is only for the party #j乃Let the 5 brothers give an example, the present invention
