It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] Please see Figure 1 This is a schematic diagram of a charging control system for a traffic light according to the first embodiment of this application. The system is used to charge the power module of the traffic light. The power module includes a signal light source 101 and a white light source 102. The charging control system includes a charging power module 103 and a driving module 104. The output terminal of the charging power module 103 is connected to the input terminal of the driving module 104, and the output terminal of the driving module 104 is connected to the input terminals of the signal light source 101 and the white light source 102. The charging power module 103 supplies power to the driving module 104. The driving module 104 receives a first charging signal from an external source to supply power to the signal light source 101, or receives a second charging signal from an external source to supply power to the white light source 102.

[0027] Specifically, the input terminal of the driver module 104 can also be connected to an external power supply 105 via a TYPE-C interface. The external power supply 105 supplies power to the driver module 104, and the driver module 104 charges the charging power module 103. The charging power module 103 can be a rechargeable battery, such as a lithium battery. During use, the charging power module 103 supplies power to the driver module 104, and the driver module 104 outputs electrical energy to the signal light source 101 or the white light source 102, thereby illuminating the signal light source 101 or the white light source 102. Furthermore, the white light source 102 in this embodiment can be replaced according to actual needs, such as using other colored light source boards for illumination.

[0028] Specifically, the parameters of the driver module 104 are shown in Table 1.

[0029] Serial Number Parameter name unit numerical values 1 TYPE-C interface input voltage VDC 5 2 Input voltage range VDC 5(±5％) 3 Charging power supply charging end output VDC 2.5-4.2 4 Maximum output current at the charging end of the charging power supply A(DC) 2 5 White light source 102 output voltage VDC 2-3 6 White light source 102 output current A(DC) 0.2

[0030] Table 1: Parameters of the driver module

[0031] The drive module 104 inputs a DC5V peripheral power supply 105 through the TYPE_C interface, outputs a DC4.2V voltage to charge the charging power supply module 103, and outputs a DC2-3V power supply to power the light source board. Electrical connections are made through leads, which is convenient and highly reliable.

[0032] In this embodiment, the charging power module 103 supplies power to the driving module 104; the driving module 104 supplies power to the signal light source 101 by receiving the first charging signal sent from the outside, or supplies power to the white light source 102 by receiving the second charging signal sent from the outside, thereby achieving both power supply to the signal light source 101 and power supply to the white light source 102.

[0033] Specifically, the drive module 104 and the white light source 102 are separate. The drive module 104 is installed inside the cavity, while the light source board is installed inside the top transparent cavity. When the power switch of the drive module 104 is briefly pressed, the drive module 104 outputs a control signal to power the signal light source 101. When the power switch of the drive module 104 is pressed and held for 1 second, the drive module 104 outputs a control signal to power the white light source 102. The charging power module 103 is powered by a lithium battery. The top white light uses a single 3030 white LED. The signal light source 101 board uses a 75-parallel connection to connect the red, green, and yellow LEDs.

[0034] Specifically, the signal light source 101 and the white light source 102 are distinguished by control.

[0035] Signal: Solid on → Flashing → Off;

[0036] White light: Press and hold the button to activate the white light on the ceiling light (usually for about 1 second), press and hold once to turn it off (usually for about 1 second). Regardless of the operating state, a long press will directly turn the white light on or off; the signal function will only cycle when the white light is off.

[0037] In a specific embodiment, the driving module 104 is further configured to control the charging mode for charging the signal light source 101 and the white light source 102 according to the charging voltage of the charging power supply; the charging mode includes constant current charging and constant voltage charging. Specifically, constant current charging emphasizes efficiency and speed, while constant voltage charging focuses more on safety and battery protection. During the charging process, a suitable charging method can be selected according to the actual condition of the battery and charging requirements to achieve the best charging effect.

[0038] In a specific embodiment, the charging mode for charging the signal light source 101 and the white light source 102 according to the charging voltage of the charging power supply includes: when the charging voltage is less than a first preset threshold, the charging mode is constant current charging; when the charging voltage is greater than or equal to the first preset threshold and less than a second preset threshold, the charging mode is constant voltage charging.

[0039] Specifically, the first and second preset thresholds can be set according to actual conditions. Different charging methods are used depending on the charging voltage. When the charging voltage is below 3V, a 100mA constant current power supply is used to trickle charge the battery. When the charging voltage is between 3V and 4.2V, a constant voltage power supply is used for charging, with a maximum charging current of 2A, and it takes about 4 hours to fully charge the battery.

[0040] In a specific embodiment, please refer to Figure 2The driving module 104 includes: a charging management chip U1, a first resistor R9, a second resistor R10, a third resistor R3, a fourth resistor R19, a fifth resistor R4, a first capacitor C1, a second capacitor C2, a third capacitor C3, a fourth capacitor C4, a fifth capacitor C5, a sixth capacitor C6, a seventh capacitor C7, a first light-emitting diode D1, a second light-emitting diode D2, a third light-emitting diode D3, a fourth light-emitting diode D4, and a first inductor L1; one end of the third resistor R3, one end of the third capacitor C3, and the first pin of the charging management chip U1 are all connected to the external power supply 105 charging chip J7. The first port is connected to the second port of the peripheral power supply 105 charging chip J7, one end of the second resistor R10 is connected to the third port of the peripheral power supply 105 charging chip J7, and the other ends of the first resistor R9, the second resistor R10, the second capacitor C2, the third capacitor C3, and the first capacitor C1 are all connected to the fourth port of the peripheral power supply 105 charging chip J7. The other end of the second capacitor C2 is connected to the other end of the third resistor R3. The positive terminal of the first light-emitting diode D1 and the second light-emitting diode D1 are connected to the fourth port of the peripheral power supply 105 charging chip J7. The negative terminals of D2 are all connected to the second pin of the charging management chip U1. The positive terminals of the third LED D3 and the negative terminals of the fourth LED D4 are all connected to the third pin of the charging management chip U1. The negative terminals of the first LED D1, the positive terminals of the second LED D2, the third LED D3, and the fourth LED D4 are all connected to the fourth pin of the charging management chip U1. The fifth pin of the charging management chip U1 is connected to the other end of the first capacitor C1 and one end of the fifth resistor R4. The seventh pin of the charging management chip U1 is connected to the first capacitor C1. One end of inductor L1 is connected to one end of the fifth capacitor C5, one end of the sixth capacitor C6, and one end of the seventh capacitor C7. The other ends of the fifth capacitor C5, the sixth capacitor C6, and the seventh capacitor C7 are connected to one end of the fourth capacitor C4, one end of the first capacitor C1, the fourth port of the peripheral power supply 105 charging chip J7, and the charging power module 103 and grounded. The other end of the fourth capacitor C4 is connected to the other end of the fifth resistor R4, the other end of the first inductor L1, and the charging power module 103.

[0041] Specifically, Figure 2In the diagram, VBAT+ represents the network name, BAT represents the charging power module 103, the first resistor R9 and the second resistor R10 are used to monitor the USB port of the peripheral power supply 105J7, and the third capacitor C3 and the second capacitor C2 constitute a surge protection circuit. A surge protection circuit limits the peak voltage, preventing excessive voltage from damaging the circuit. This is typically achieved by connecting voltage-limiting components (such as varistors, gas discharge tubes, etc.). When the voltage exceeds a set value, these components conduct and shunt current, thereby reducing the voltage. At the moment of power-on, the surge current may be much greater than the steady-state input current. The surge protection circuit, through the connection of resistors, inductors, and other components, can limit the peak current, protecting the circuit from the impact of surge current. In some cases, the surge protection circuit can also act as an isolation device, isolating the surge signal from the main circuit, thus preventing the surge from directly affecting the circuit.

[0042] The third capacitor C3 is a coupling capacitor. The first LED D1, second LED D2, third LED D3, and fourth LED D4 are power indicator lights for the charging power module 103. Specifically, when the charging power module 103 is fully charged, all four indicator lights are on; when it is 75% charged, three indicator lights are on; when it is between 75% and 25% charged, two indicator lights are on; when it is less than 25% charged, one indicator light is on; and when the power module 103 is 0%, all indicator lights are on. The correspondence between the percentage of charge and the number of indicator lights can be set according to actual conditions. Furthermore, Figure 2 The first inductor L1 is the charging inductor, the fifth resistor R4 and the first capacitor C1 are used to detect the voltage of the charging power module 103, the fourth resistor R19 is used to output the button signal, and the fourth capacitor C4, the fifth capacitor C5, the sixth capacitor C6 and the seventh capacitor C7 are filter capacitors.

[0043] In a specific embodiment, the driving module 104 is further configured to power off when the charging voltage of the charging power supply is lower than a third preset threshold; the third preset threshold is lower than the first preset threshold. Specifically, the charging voltage of the charging power supply is monitored, and when the charging voltage is lower than 2.7V, the output is automatically turned off and the power supply enters a sleep state to prevent the charging power supply from entering an over-discharge state.

[0044] In a specific embodiment, please refer to Figure 3The driving module 104 further includes a main control chip U3, a switching chip K1, an eighth capacitor C11, a ninth capacitor C12, a tenth capacitor C9, and a sixth resistor R17. One end of the eighth capacitor C11, one end of the ninth capacitor C12, and the second pin of the main control chip U3 are connected to the charging power module 103. The other ends of the eighth capacitor C11 and the ninth capacitor C12 are connected to the ground pin of the main control chip U3, one end of the tenth capacitor C9, the first pin of the switching chip K1, and the second pin of the switching chip K1. The other end of the tenth capacitor C9 is connected to the seventh pin of the main control chip U3, the third pin of the switching chip K1, the fourth pin of the switching chip K1, and one end of the sixth resistor R17. The other end of the sixth resistor R17 is connected to the charging power module 103.

[0045] Specifically, VBAT+ connects to the charging power supply, the eighth capacitor C11 is a rectifier capacitor, the ninth capacitor C12 is a coupling capacitor, the tenth capacitor C9 and the sixth resistor R17 constitute a reset circuit, and the key is a switching chip. When the system is powered on, the reset circuit sends a reset signal to correctly initialize all system components and registers. This ensures that the system is in a known state at startup, avoiding unknown problems caused by power-on. For microcomputer circuits, the primary function of the reset circuit is power-on reset; the reset signal is removed only after the power supply has stabilized, allowing the circuit to begin normal operation.

[0046] In a specific embodiment, this application has two light source boards: one is a top white light source board 102, and the other is a signal light light source board. The top light source board uses a 3030 packaged white light source 102 with a forward voltage (150mA): 2.9V-3.3V; the signal light uses a 0603 packaged light source with a forward voltage (200mA): 2V-3V. Three light sources are available according to product requirements: red, green, and yellow.

[0047] Battery parameters are as follows: Battery specifications: 21700, open circuit voltage 2.5V~4.2V, battery capacity ≥5000mAh, over-discharge protection voltage: 2.5±0.1V, overcharge protection voltage 4.28±0.05V. Charging principle explanation:

[0048] The charging system uses the mature domestic IP5306 solution. It supports 4 LEDs for power display. It features output overcurrent, overvoltage, and short-circuit protection. It also features input overvoltage, overcharge, over-discharge, and overcurrent discharge protection. Over-temperature protection is supported. The TYPE-C interface receives a DC 5V power input and outputs a DC 4.2V power supply to charge the lithium battery. Different charging methods are used depending on the battery voltage. When the battery voltage is below 3V, a 100mA constant current power supply is used for trickle charging. When the battery voltage is between 3V and 4.2V, a constant voltage power supply is used for charging. The maximum charging current is 2A, and it takes approximately 4 hours to fully charge.

[0049] This application features high reliability and environmental adaptability, and can operate normally in environments ranging from -20℃ to +40℃. It adopts a commercially available TYPE-C charging interface, has a power display and low power warning function, and the command signal illumination mode can be switched between constant light and flashing state, providing an ultra-long battery life of more than 24 hours.

[0052] Step 202: When the charging voltage is less than the first preset threshold, the driving module charges the signal light source or the white light source using a constant current charging mode.

[0053] Step 203: When the charging voltage is greater than or equal to the first preset threshold and less than the second preset threshold, the driving module charges the signal light source or the white light source using a constant voltage charging mode.

[0054] Specifically, the first and second preset thresholds can be set according to actual conditions. Different charging methods are used depending on the charging voltage. When the charging voltage is below 3V, a 100mA constant current power supply is used to trickle charge the battery. When the charging voltage is between 3V and 4.2V, a constant voltage power supply is used for charging, with a maximum charging current of 2A, and it takes about 4 hours to fully charge the battery.

[0055] In a specific embodiment, the method further includes: powering off the drive module 104 when the charging voltage of the charging power supply is lower than a third preset threshold; the third preset threshold is lower than the first preset threshold. Specifically, the charging voltage of the charging power supply is monitored, and when the charging voltage is lower than 2.7V, the output is automatically turned off and the system enters sleep mode to prevent the charging power supply from entering an over-discharge state.
