All of the above are existing technologies. The power supply control board uses 12V power supply and RS485 communication. It provides RS485 communication with the fixed column screens and power management module in the mobile shelving unit, RS232 communication with the touch screen 2, and CAN communication with the control module in the mobile shelving unit. This is existing technology. The CAN communication module is a communication interface module based on the CAN bus protocol, used to realize real-time data transmission and control between devices. In addition to connecting to the mains power, the power supply also includes a UPS battery, which can support UPS online power supply. The power management module provides power to the fixed column screens in the mobile shelving unit after conversion through a 12V adapter and exchanges information through RS485 communication. The power supply is supported by the cabinet 3 and the door 1. The power management module converts the mains power into a suitable voltage and then supplies power to the mobile shelving unit and the power supply control board, while also protecting the circuit. The power supply control board and the touch screen 2 are electrically connected to supply 12V power to the touch screen 2. The power supply control board monitors the current and voltage at the input terminals of the mobile shelving unit in real time and collects information such as the status (moving / idle) of the mobile shelving unit through the mobile shelving unit. This information is then transmitted to the power supply control board for storage, processing, and analysis via the CAN communication module, and finally transmitted to the touch screen 2 for display. This achieves the function of real-time monitoring of the power supply and reduces the complexity of power management. The power supply control board, mobile shelving units, and power management module interact via a CAN communication module, enabling collaborative operation.

The temperature and humidity of the power supply's operating environment are measured in real time through a temperature and humidity sensor. Data interaction between the microprocessor, the mobile shelving unit, and the power management module is achieved through a CAN communication module. The above information is then transmitted to the microprocessor for storage, processing, and analysis, and displayed on the touch screen 2. This enables the power supply control board to collect and display the power supply data.

[0030] Reference Figure 3 , Figure 4 and Figure 5 The power management module includes a power management circuit board, an electricity meter, an air switch, and a surge protector. The surge protector and the air switch are electrically connected. The air switch and the electricity meter are electrically connected. The power management circuit board is electrically connected to the CAN communication module, the mobile shelving unit, the electricity meter, and the microprocessor. The microprocessor is electrically connected to the electricity meter. Specifically, the power management circuit board can use a PLC controller or a microcontroller; the surge protector is the LEEYEE LY1-B60 surge protector; the air switch can be the Schneider C32 air switch; and the energy meter is the Chint Kunlun DDSU666 series single-phase electronic energy meter (DIN rail), which adopts standard DIN35mm DIN rail mounting and communicates with the microprocessor via RS485. Communication supports ModBus-RTU and DL / T645-2007. The power management circuit board is electrically connected to a 12V adapter, which converts the voltage to power the fixed column screens in the mobile shelving unit. The information of the mobile shelving unit, the power management circuit board and the microprocessor are transmitted through RS485 communication between the fixed column screens, the power management circuit board and the microprocessor, and through the CAN communication module. By connecting the mains power to a surge protector, damage to downstream equipment caused by surge voltages such as lightning strikes can be prevented. Through the electrical connection between the surge protector and the air switch, the air switch automatically trips and disconnects the circuit when the current in the circuit exceeds the rated value or a short circuit fault occurs. Through the electrical connection between the air switch and the electricity meter, the electricity meter can measure the power consumption, current, and voltage in the circuit and transmit the information to the microprocessor for storage, processing, and analysis, thereby realizing the safe power supply function of the power management module.

[0031] Reference Figure 5 The power management circuit board is electrically connected to a switching power supply, which is electrically connected to the mobile shelving unit. The power management circuit board is also electrically connected to an electronic button lock, which is electrically connected to the mobile shelving unit. Specifically, the switching power supply is a Mornsun LMF1000-20B24 1000W metal-cased power supply. There are multiple switching power supplies, and the input terminals of each switching power supply are connected to the power management circuit board. The output terminal of each switching power supply is connected to a mobile shelving unit. The electronic button lock is powered by a power management circuit board, and the electronic button lock and the control module in the mobile shelving unit are bidirectionally connected. Relevant commands are input through the fixed column screen in the mobile shelving unit, and then controlled by the control module in the mobile shelving unit. The mobile shelving can be locked, unlocked, and its status can be viewed. The signal transmission of the CAN communication module can also be used to view and input commands through the touch screen 2 to control the locking and unlocking status of the mobile shelving, thereby helping to realize the control function of the mobile shelving. The power management circuit board transmits electrical energy to the switching power supply, which converts the 220V voltage to 24V to power the mobile shelving unit, thus realizing the function of powering the mobile shelving unit.

[0032] Reference Figure 4 and Figure 6 The microprocessor is electrically connected to the fan 4 and the audible and visual alarm light. The fan 4, the temperature and humidity sensor and the audible and visual alarm light are all located inside the housing 3. The air outlet of the fan 4 passes through one side of the housing 3. Specifically, fan 4 uses a counter-clockwise rotating Kowloon JL7025H12B fan and is bidirectionally connected to the microprocessor, which can provide feedback on its own operating status. The audible and visual alarm uses a Chint ND16-22FS buzzer. The temperature and humidity sensor monitors the internal temperature of the enclosure 3 in real time and transmits the signal to the microprocessor. When the internal temperature of the enclosure 3 exceeds the preset value, the power supply control board controls the fan 4 to start, which accelerates the air circulation inside and outside the enclosure 3, removes heat, and improves the heat dissipation capacity. When the temperature continues to exceed the preset value or there is an abnormality inside the power supply, the microprocessor controls the sound and light alarm light to issue a sound and light alarm, reminding relevant personnel to disconnect the power for maintenance.

For example, new sensors or other devices can be connected later according to actual needs to increase monitoring and control functions and improve the intelligence and adaptability of the power supply.

[0034] Reference Figure 5 and Figure 7 The power management circuit board is electrically connected to a power switch 6; Specifically, the power supply switch 6 transmits the signal to the power management circuit board, and the power management circuit board transmits the signal to the switching power supply, thereby enabling convenient control of the power supply for the mobile shelving unit.

[0035] Reference Figure 1 , Figure 4 and Figure 7 The interior of the enclosure 3 is equipped with a protective door 5. The power switch 6 is located on the side of the protective door 5 near the enclosure door 1. The power control board, power management module, fan 4 and audible and visual alarm lights are all located between the protective door 5 and the side wall of the enclosure 3. Specifically, the protective door 5 separates the enclosure 3 into two spaces, storing the power supply control board, power management module, fan 4, and audible and visual alarm lights in the inner layer of the enclosure 3. This reduces the possibility of electric shock and achieves physical isolation between personnel and internal electrical components during operation, thereby ensuring the safety of operators.

[0036] Working principle: When using this power supply, the mains power is connected to the surge protector, and the power supply is safely supplied through the air switch. The power consumption, current and voltage in the input terminal of the power management circuit board are measured in real time by the energy meter, and the information is transmitted to the microprocessor for storage, processing and analysis through RS485 communication. Then it is displayed on the touch screen 2, thus realizing the function of real-time monitoring and display of mains power input. The power supply measures the input current and voltage of the mobile shelving unit in real time using a current transformer, measures the temperature and humidity of the operating environment in real time using a temperature and humidity sensor, monitors the status of the mobile shelving unit using a detection sensor module, receives feedback on the status of fan 4, and achieves data interaction between the power supply control board, the mobile shelving unit, and the power management module through a CAN communication module. After the above information is transmitted to the microprocessor for storage, processing, and analysis, it is displayed on the touch screen 2. This enables the collection and display of information such as voltage, current, temperature and humidity, power consumption, status of cooling fan 4, status of mobile shelving, and alarms in the power supply, and also allows for long-term storage of historical data and alarm information. Commands can also be input via touchscreen 2 and transmitted to the power management module and mobile shelving unit via CAN communication module through the power box control board to adjust the power supply strategy, or to provide feedback on the power supply status for comprehensive judgment by the power box control board.
