[0046] In this embodiment, the first MOS tube Q1 and the second resistor R2 form a level conversion circuit, and when the high level of the serial port of the first interface is 3.3v, the high level transmitted to the first signal receiving terminal PA13 of the first control chip U3 is guaranteed to be 2.5v. And when the first interface voltage of the mobile lighting device is charged is 2.5-4.2v, the voltage between the gate terminal and the source terminal of the first MOS tube Q1 does not meet the conduction condition, so the first MOS tube Q1 is turned off to protect the I / O port voltage of the first control chip U3 from being too high.

After being processed by the second control chip U7, the program is transmitted to the first control chip U3 of the mobile lighting device through the second interface circuit and the first interface circuit, thereby realizing the program upgrade of the mobile lighting device.

[0049] It should be noted that the second signal sending end PA14 and the second signal receiving end PA13 of the second control chip U7 of the auxiliary device and the first signal sending end PA14 and the first signal receiving end PA13 of the first control chip U3 of the mobile lighting device transmit data through a half-duplex serial port protocol. When the auxiliary device sends data to the mobile lighting device, the second signal sending end PA14 of the second control chip U7 serves as the sending end, and the first signal receiving end PA13 of the first control chip U3 of the mobile lighting device serves as the receiving end. When the second signal sending end PA14 sends a high level, the second diode D4 is not turned on, the first MOS tube Q1 of the mobile lighting device is not turned on, and the second resistor R2 and the first resistor R1 form a series connection to pull the first signal receiving end PA13 to a high level; when the second signal sending end PA14 of the second control chip U7 sends a low level, the second diode D4 is turned on, the first MOS tube Q1 of the mobile lighting device is turned on, and the first signal receiving end PA13 is pulled down to a low level.

When the first signal sending end PA14 sends a high level, the first diode D2 is not turned on, the first MOS tube Q1 is not turned on, and the second signal receiving end PA13 of the second control chip U7 of the auxiliary device is pulled up to a high level; when the first signal sending end PA14 sends a low level, the first diode D2 is turned on, the first MOS tube Q1 is turned on, and the second signal receiving end PA13 of the second control chip U7 of the auxiliary device is pulled up Low level; wherein, the function of the first diode D2 and the second diode D4 is mainly that when the signal received by the first signal receiving end PA13 or the second signal receiving end PA13 on one side is a low level, the first signal sending end PA14 or the second signal sending end PA14 on the same side can still maintain a high level; when the first signal sending end PA14 or the second signal sending end PA14 sends a signal, the first signal receiving end PA13 or the second signal receiving end PA13 on the same side will also receive the signal. Therefore, during the upgrade, it is necessary to set that when the sending end sends a signal, the signal of the receiving end on the same side will not be processed, and the communication process uses half-duplex serial port communication.
