[0005] However, the above technical solution cannot determine the load protocol and cannot perform intelligent monitoring. Summary of the invention

[0006] In view of this, the present invention provides an intelligent voice fully compatible charger.

[0007] The technical solution adopted by the present invention is:

[0008] An intelligent voice fully compatible charger, comprising:

[0009] The rectifier circuit converts the AC power output of the power supply into a DC regulated voltage and inputs it into the microcontroller.

[0010] The single-chip microcomputer receives the DC regulated voltage signal, automatically identifies the load-side charging protocol, outputs the matching charging voltage to charge the battery, and triggers the voice conversion controller to broadcast the charging process through the speaker;

[0011] The temperature control circuit monitors the ambient temperature of the directional output DC regulated voltage process in the rectifier circuit. During the monitoring process, the temperature detection system of the U1 controller is triggered to detect and compare the ambient temperature, trigger the voice conversion controller to broadcast the charging process through the speaker, and trigger the intelligent safety protection system to start and close the automatic power-off protection;

[0012] The load-end detection circuit identifies and detects the charging status of the load end and triggers the single-chip protection system to protect the charging process of the load end, and triggers the voice conversion controller to voice broadcast the charging process through the speaker L1.

[0049] Furthermore, the rectification and filtering circuit is a voice conversion controller of the AM4FA type, the voice conversion controller AM4FA converts the voice into a voice signal, and the speaker voice broadcast protocol has been identified.

[0050] Furthermore, the temperature control of the U1 controller temperature detection system is as follows: when the charging temperature reaches 75-85 degrees due to unstable input voltage, load overload, device aging, high ambient temperature, etc. during charging, the U1 controller temperature detection system is triggered, and the signal is transmitted to the voice conversion controller and converted into a voice signal, which is broadcasted by the speaker. However, when the temperature reaches above 90 degrees, the intelligent safety protection system is triggered to automatically cut off the power for protection.

[0051] Furthermore, when the rated power is exceeded during the charging process, the single chip microcomputer protection system is triggered, and the signal is input into the voice conversion controller and converted into a voice signal, the speaker makes a voice announcement, and the power is automatically cut off within 3 seconds for safety protection.

[0052] During operation, 100V-240V AC power outputs DC voltage in a directional manner (positive and negative) through the BD1 bridge rectifier circuit, and outputs DC regulated voltage after voltage transformation through the main control transformer IC. After rectification and filtering by ICU2, it is input into the microcontroller (XPD636B) for protocol identification of the load-end charging protocol to start charging.
