[0027] Reference Figure 4, the relay output control circuit 3 is divided into two groups of control outputs which are respectively connected to two power sockets. The first group consists of triode Q1, relay REL1, resistors R61 and R71; the second group consists of triode Q2, relay REL2, resistors R62 and R72. The HC32F176KATA chip of the single-chip microcomputer control circuit 1 controls the conduction or disconnection of triode Q1 or triode Q2 by pulling high or pulling low the base of triode Q1 or triode Q2, so that the coil of relay REL1 or relay REL2 is energized / de-energized, achieving the effect of attracting or disconnecting relay REL1 or relay REL2. When relay REL1 or relay REL2 is attracted, the neutral wire of the power socket output circuit is energized, and the external charging device can be powered; when relay REL1 or relay REL2 is disconnected, the neutral wire of the power socket output circuit is open-circuited and cannot be externally powered.

[0028] Reference Figure 8 , the voltage detection circuit 7 consists of resistors R44, R45, R46, R47, R48, R49 and capacitor C21. Resistors R44, R45, R46, R47 and R48 are connected in series, and resistor R49 is connected to resistor R48 for voltage division to the ground, obtaining a voltage and transmitting it to the metering detection chip U6 of the power detection circuit 8. The metering detection chip U6 of the power detection circuit 8 calculates the current AC voltage obtained and transmits it to the HC32F176KATA chip of the single-chip microcomputer control circuit 1 through the serial port.

[0029] Reference Figure 10 , the power detection circuit 8 is divided into two paths to detect power. The first path consists of resistors R1, R2, R21, capacitors C1, C2 and the third and fourth pin IO ports of the metering detection chip U6; the second path consists of resistors R3, R4, R22, capacitors C3, C4 and the fifth and sixth pin IO ports of the metering detection chip U6. When the charging port of the power socket connected to the first path is externally powered, a voltage will be generated at both ends of resistor R21 and transmitted to the third and fourth pin IO ports of the metering detection chip U6 respectively. The metering detection chip U6 calculates the real-time current passing through resistor R21 at present, thereby obtaining the corresponding power, and communicates with the HC32F176KATA chip of the single-chip microcomputer control circuit 1 through the serial port to transmit the real-time charging power and the total charging power. The principle of the second path is the same as that of the first path.

[0030] Reference Figure 5, the plug detection circuit 12 is divided into two detection paths. The first detection path consists of diode D6, triode Q9, resistors R7, R8, R9, R10, R15, R16, and capacitor C11; the second detection path consists of diode D7, triode Q10, resistors R23, R24, R25, R26, R27, R28, and capacitor C12. When the power socket is not plugged with a plug, there is no voltage at the base of triode Q9 or triode Q10, triode Q9 or triode Q10 is not conducting, and the collector is at a high level. The IO port of the HC32F176KATA chip in the single-chip microcomputer control circuit 1 connected is also at a high level; when the power socket is plugged with a plug, the base voltage of triode Q9 or triode Q10 is high, triode Q9 or triode Q10 conducts, and the collector is at a low level. The IO port of the HC32F176KATA chip in the single-chip microcomputer control circuit 1 connected is also at a low level. The HC32F176KATA chip in the single-chip microcomputer control circuit 1 determines that the power socket has been plugged with a charging plug for the device to be charged.

[0031] Reference Figure 6 , the anti-disassembly detection circuit 13 consists of resistor R5 and microswitch K1. When the device shell is closed, the microswitch K1 presses against the back cover of the shell to make both ends conduct, and the IO port of the HC32F176KATA chip in the single-chip microcomputer control circuit 1 is at a low level. When the shell is opened, the microswitch K1 pops up and both ends are short-circuited, and the IO port of the HC32F176KATA chip in the single-chip microcomputer control circuit 1 is at a high level.

[0032] Reference Figure 9 , the AC-DC circuit 2 consists of resistors R80, R81, R82, R83, capacitors C101, C102, C103, C10, C60, C61, diodes D3, D4, D8, inductors L1, L2, varistor RV1, square fuse F1, glass tube fuse F2, safety capacitor C110, and dedicated AC-DC integrated chip U7. After the alternating current passes through the square fuse F1 and the glass tube fuse F2, it passes through a filtering circuit composed of capacitors C101, C102, and inductor L1, and then enters the dedicated AC-DC integrated chip to be converted into DC12V output to supply power to the whole machine.

[0033] Reference Figure 7, the battery charging circuit 6 consists of resistors R50, R52, R88, R89, capacitor E1, diode D12, field effect transistor Q12, and dedicated charging chip U12. When the AC power supply is normal, the device is powered by the DC 12V converted from AC. The dedicated charging chip U12 generates a voltage to charge the battery 5 BATT. At this time, due to the cutoff of the field effect transistor Q12, the battery 5 only charges and does not supply power. When the AC power is cut off, the field effect transistor Q12 conducts forward, and the battery 5 supplies power to the device, ensuring that the device can transmit the AC power-off information to the HC32F176KATA chip of the microcontroller control circuit 1 and notify the user of the AC power-off information through the LTE module, so as to promptly troubleshoot faults and restore AC power.

[0034] Working principle: The mains power is converted into a DC voltage through the AC-DC output circuit to provide the working voltage required for the power socket, battery charging circuit, microcontroller control circuit, and LTE module. The battery charging circuit charges the backup battery. When the user charges the electric vehicle, they only need to scan the QR code or swipe the card to connect to the microcontroller control circuit. The microcontroller control circuit controls the relay output control circuit to close, so that the mains power supplies power to the electric vehicle charger plug on the power socket through the relay output control circuit, and then charges the battery of the electric vehicle; the power detection circuit detects the power consumption of each power socket and sends it to the metering chip, communicates with the microcontroller control circuit through the serial port, and monitors the charging situation in real time. The plug detection circuit detects whether the charging plug is inserted into the power socket in real time and sends it to the microcontroller control circuit. The voltage detection circuit detects the voltage of the battery charging circuit in real time, and after being metered by the power detection circuit, it is sent to the microcontroller control circuit. When the plug detection circuit detects that the charging plug is inserted into the power socket, but the metering detection circuit collects no voltage information, it will remind the user to swipe the card or scan the code to charge. When the microcontroller control circuit can accurately judge the mains power-off fault of the charging pile according to the battery power supply status combined with the detection information of the plug detection circuit and the voltage detection circuit, when the AC power of the device is cut off, the internal backup battery will maintain the operation of the device and promptly notify the administrator of the AC power-off information to troubleshoot faults in the device or the AC circuit. When the anti-tamper detection circuit is triggered or the plug detection circuit does not detect the charging plug, and the voltage detection circuit detects no voltage and the battery supplies power to the microcontroller control circuit, it is inferred that there may be a fault warning such as power-off or charging seat damage caused by the charging seat being damaged or stolen. When the microcontroller control circuit determines a power-off fault alarm or fault warning, it immediately sends the power-off fault alarm or fault warning information of the charging seat to the LTE module, and then the LTE module sends the power-off fault alarm or fault warning information to the platform server through the cloud server for alarm or warning, so that the background maintenance personnel can immediately repair the charging pile with a power-off fault or eliminate the generated fault warning, so that the background maintenance personnel can immediately repair the charging pile with a fault.

[0035] In the above embodiments, the voltage value detected by the voltage detection circuit can also be directly transmitted to the single-chip microcomputer control circuit to collect the voltage value data. The micro switch of the anti-disassembly detection circuit can also directly press against the mounting bracket of the charging base, and detection can also be triggered when the charging base is separated from the mounting bracket of the charging base. One power socket can be provided on the charging base, or three, four or more power sockets can be provided. Only one plug detection circuit needs to be configured for each power socket for detection. At the same time, the relay output control circuit also correspondingly matches the number of control output terminals according to the number of power sockets. A smartphone APP can also be added, that is, the platform server communicates with the smartphone APP to transmit power-off warning information, so that the alarm can be quickly sent to the relevant responsible person of the charging pile to immediately handle the alarm and quickly handle the power-off fault of the charging pile. A fault indicator light can also be added, and the output terminal of the single-chip microcomputer control circuit is connected to the fault indicator light for displaying power-off faults.

[0036] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all of them fall within the protection scope of the present invention.
