[0028] The embodiment of the present invention provides a smart charging cabinet with power management and charging protection functions, such as Figure 1 、 Figure 2 and Figure 3 As shown, the smart charging cabinet includes a tool cabinet and a power management terminal.

[0029] The tool cabinet includes a cabinet body and a door. The cabinet body is equipped with sensors such as an RFID antenna and a weighing module. Furthermore, the cabinet body is divided into multiple charging compartments for charging devices by multiple supporting partitions. Each charging compartment is equipped with a power management terminal on the front. In this embodiment, the tool cabinet adopts an independent compartment design, with a total of eight charging compartments.

[0030] The smart charging cabinet has functions such as overheating alarm, leakage protection, and automatic power-off upon full charge. It has built-in temperature sensors, leakage protection devices, power detection chips and other structures or components. They are connected through circuits and work together under the coordination of the control system. The details are as follows:

[0031] (1) Overheat alarm and power-off function

[0032] Structural components: temperature sensor, temperature control system, sound and light alarm and power control circuit are set.

[0033] Connection method: The temperature sensor is installed in the charging grid and connected to the temperature control system through a line. The temperature control system is electrically connected to the sound and light alarm and the power control circuit.

[0034] Working Principle: A temperature sensor monitors the temperature inside the charging compartment in real time. When the temperature exceeds a preset value, it transmits a signal to the temperature control system. Upon receiving the signal, the temperature control system controls the sound and light alarm to sound an audible and visual alarm, simultaneously triggering the power control circuit to cut off power to the charging device in the corresponding charging compartment. The system also records and transmits abnormal information to the operation terminal, displaying it on the main interface.

[0035] (2) Smoke alarm function:

[0036] Structural components: smoke sensor, sound and light alarm and power control circuit are set.

[0037] Connection method: The smoke sensor is installed at a suitable position in the cabinet and connected to the sound and light alarm and power control circuit through lines.

[0038] Working principle: The smoke sensor monitors the smoke concentration in the cabinet in real time. When it detects that the smoke concentration exceeds the set value, it transmits the signal to the power control circuit and the sound and light alarm. The sound and light alarm sounds an sound and light alarm. At the same time, the power control circuit cuts off the entire charging power supply and records the abnormal information and uploads it to the operation terminal for display.

[0039] (3) Anti-leakage and electric shock protection function:

[0040] Structural components: Equipped with a leakage protection device, usually an electronic circuit breaker system or a leakage switch, and an AC220V AC socket is reserved in each charging grid.

[0041] Connection method: The leakage protection device is connected in series in the charging circuit and electrically connected to the AC220V AC socket.

[0042] Working principle: The leakage protection device monitors the circuit status in real time. When it detects that the leakage current or abnormal current exceeds the set value, it will cut off the circuit in a very short time (such as 0.02 seconds), thereby preventing electric shock accidents and ensuring user safety.

[0043] (4) Automatic full power off and charging time setting function:

[0044] Structural components: including power detection chip, intelligent control system and power control switch.

[0045] Connection method: The power detection chip is connected to the charging device to monitor the power in real time. At the same time, it is electrically connected to the intelligent control system, and the intelligent control system is connected to the power control switch.

[0046] Working Principle: The power detection chip monitors the charging device's charge level in real time and transmits this data to the intelligent control system. When the charge level reaches the preset full charge threshold, the intelligent control system controls the power control switch to cut off the power. For the charging duration setting function, the user sets the charging time through the terminal. The intelligent control system records the set value and counts the time. When the set time is reached, the power control switch is controlled to cut off the power.

[0047] (5) Lighting function:

[0048] Structural components: Equipped with lighting and infrared sensors, some may also be equipped with light control sensors.

[0049] Connection method: The infrared sensor, light control sensor and light lamp are connected through a circuit and powered by the charging cabinet power system.

[0050] Working principle: The light control sensor senses the brightness of the external light. When the external light is dim, if the infrared sensor detects that someone is approaching the charging cabinet, it will automatically control the light to turn on, which is convenient for user operation. After the person leaves, the light will automatically turn off after the set time.

[0069] Multifunctional charging grid: Each charging grid is equipped with multiple protection functions. A temperature control system is installed within the grid, and the internal temperature of the cabinet can be set through the screen. When a grid is charging, if the temperature exceeds the preset value, the tool cabinet will immediately sound an audible and visual alarm and automatically cut off the power supply to the charging device in the grid. The system also records the abnormal information and displays it on the main interface of the operation terminal, allowing management personnel to understand the situation in a timely manner. In addition, the charging grid has comprehensive protection against leakage and electric shock. Each grid is equipped with a reserved AC220V AC socket for convenient charging of equipment.
