[0046] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model more clear, the technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are some embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0047] In the prior art, data burning of Micro SD cards is usually carried out by single-port or a small number of multi-port burners. Such burning methods usually have the following characteristics:

[0048] 1. Single-port burner: only one Micro SD card can be burned at a time, and the operator needs to frequently change the card, resulting in low efficiency;

[0049] 2. Small multi-port burner: usually has 2-4 burning ports, can burn a small number of Micro SD cards at the same time, but still cannot meet the needs of large-scale production;

[0050] 3. Power supply method: mostly dependent on USB interface power supply, which may not be stable in long-time high-load work.

[0051] 4. Expandability: most existing burners lack expansion interfaces and cannot increase the burning capacity by serial connection. In addition, each burning port usually needs to be operated separately, and there is a lack of unified batch burning management software.

[0052] The current burning method has the following main shortcomings:

[0053] 1. Low burning efficiency: single-port or small multi-port design cannot meet the needs of large-scale production, resulting in prolonged production cycle;

[0054] 2. High labor cost: the operator needs to frequently change the Micro SD card, increasing the labor consumption.

[0055] 3. Unstable power supply: dependent on USB power supply may cause power supply problems in high-load work.

[0056] 5. Poor expandability: cannot flexibly adjust the burning capacity according to production needs.

[0057] 6. Complex management: lack of unified batch management software, increasing the operation difficulty and error risk.

[0058] These problems are particularly prominent in large-scale Micro SD card production, seriously affecting production efficiency and product quality. Therefore, there is an urgent need for a multi-port Micro SD card parallel burning system that can solve the above problems.

[0059] In order to solve the above problems, a multi-port Micro SD card parallel burning system is provided in the present specification. Please refer to Figure 1 , which includes:

[0060] Substrate 10: used to install other components in the system, such as the memory card slot mentioned later and various interfaces. In this embodiment, an outer shell is provided outside the substrate to accommodate and protect the internal components (including the substrate).

[0061] In the embodiment, the unit area burning capacity is improved by the compact design of integrating the core components on the substrate 10, which is particularly suitable for the production environment with limited space.

[0062] A plurality of memory card slots 20 are arranged on the substrate 10, and each memory card slot is used to insert a Micro SD card to be burned. Such intelligent fault detection and isolation mechanism makes the failure of a single burning unit not affect the whole system operation.

[0063] The host computer signal interface 30 is arranged on the substrate 10 and is used to connect the PC host computer to transmit the data and control signals of the host computer. For example, the USB interface is used as the host computer signal interface 30.

[0064] The external power supply interface 40 is arranged on the substrate 10 and is used to connect the external power supply to ensure stable power supply of the whole system. In the embodiment, the direct current power supply can be used for power supply.

[0065] The serial interface 50 is arranged on the substrate 10 and is used to connect a plurality of external devices to expand the burning capacity of the system. The arrangement of the serial interface 50 makes it easy for multiple devices to be cascaded and supports unlimited expansion. In actual test, through the stable connection of multiple devices, it is equivalent to burning multiple Micro SD cards at the same time, which greatly improves the parallel burning processing capacity. The design of the serial interface 50 makes the system easily adapt to new Micro SD cards or other storage media in the future, prolongs the life cycle of the device, and allows the production line to flexibly adjust the scale according to the order quantity, from small batch production to large-scale manufacturing, only by simply increasing or decreasing the number of devices, without changing the overall architecture.

[0066] It should be noted that if the burning capacity needs to be expanded, a plurality of devices can be connected through the serial interface 50, and corresponding configuration can be made in the host computer software.

[0067] In some cases, the serial interface 50 can also greatly reduce the number of necessary connection lines, reducing the wiring complexity by about 80%. This not only simplifies the installation process, but also makes daily maintenance and troubleshooting easier.

[0068] A plurality of multi-channel burning controllers 60 are arranged on the substrate 10 and equal to the number of memory card slots 20, and each memory card slot 20 corresponds to an independent multi-channel burning controller 60. Parallel burning is realized through the arrangement of the memory card slot 20, the serial interface 50 and the multi-channel burning controller 60.

[0069] Main controller: set on the substrate 10, the main controller is responsible for coordinating the work of the whole system, including data transmission, burning control and state monitoring, etc., the above-mentioned memory card slot 20, host computer signal interface 30, external power supply interface 40, series interface 50 and multi-channel burning controller 60 are electrically connected with the main controller.

[0070] In this embodiment, the main controller adopts ESP32 chip. The powerful processing capability of ESP32 chip allows preliminary data analysis on site, which can provide real-time burning quality and efficiency report to help operators make optimization decisions quickly. The ESP32 chip also integrates Wi-Fi function, realizing completely wireless remote management and real-time monitoring. Operators can monitor the burning progress at any time and anywhere through mobile phones or tablet computers. This high degree of automation and remote management capability significantly improves management efficiency. At the same time, thanks to the low power consumption characteristics and intelligent power management of ESP32, the energy consumption per unit of data is reduced by about 75% compared with the USB burning scheme. In large-scale production, it can also bring significant energy-saving effect.

[0071] Unlike the traditional USB port burning scheme, in which each port can only burn one Micro SD card, in this embodiment, through the series interface 50 and the use of ESP32 chip as the main controller, parallel burning of multiple Micro SD cards is realized through a single physical interface. In the same physical space, the burning efficiency is significantly improved, and the required number of physical interfaces is also greatly reduced, which can reduce the hardware cost by about 60-70%, saving a lot of hardware cost for enterprises. This ultra-high parallelism and intelligent management can greatly shorten the burning time of large quantities of Micro SD cards, shorten the time from production to market by 40-50%, improve market response speed, and realize more strict access control and data encryption compared with dispersed USB interfaces.

[0072] Voltage conversion module: set on the substrate 10, electrically connected with the main controller, used for converting external power into various voltages required by the system. For example, DC-DC voltage conversion.

[0073] Power management module: set on the substrate 10, electrically connected with the main controller, used for monitoring and adjusting the power supply state of each part to ensure stable work.

[0074] The above-mentioned voltage conversion module and power management module jointly constitute the power supply module of the system, both of which are set on the substrate 10 and electrically connected with the main controller.

[0075] In the embodiment, an indication module is also provided for each memory card slot 20, which is electrically connected with the main controller and the corresponding memory card slot 20. Specifically, the indication module is composed of three LED indicators, including:

[0076] Power indication light: used for displaying whether the card reader device is normally powered.

[0077] Insertion indication light: used for displaying whether a Micro SD card is detected.

[0078] Read-write indication light: used for displaying the read-write state in the burning process.

[0079] In the embodiment, in order to better manage the signals transmitted by the host computer, the system is also provided with:

[0080] Host computer signal controller: provided on the substrate 10, which is electrically connected with the main controller and the host computer signal interface 30, and is used for managing the data transmission between the system and the host computer.

[0081] Buffer module: provided on the substrate 10, which is electrically connected with the main controller, and is used for temporarily storing the data to be burned, so as to improve the data transmission efficiency.

[0082] Correspondingly, the host computer can provide a burning management interface, which is used for controlling the burning process, monitoring the burning state and managing the burning task; a data preprocessing module, which is used for preprocessing and checking the data to be burned; and a device monitoring module, which is used for real-time monitoring the working state of multiple parallel burning devices.

[0083] When multiple Micro SD cards are burned in parallel, a large amount of heat will be generated in the whole system. In the embodiment, a heat dissipation module is also provided, which includes:

[0084] Heat dissipation fan: provided on the substrate 10, which is used for forcibly cooling the system to ensure stable operation for a long time.

[0085] Heat dissipation fin: provided on the substrate 10 and installed near the heat generating elements in the core, which is used for auxiliary heat dissipation.

[0086] The working process of the system is as follows:

[0087] Connect external power supply through external power supply interface 40, ensure stable power supply;Through the host computer signal interface 30, the system is connected to PC host computer;Start the host computer software, identify the connected burning device;Insert the Micro SD card to be burned into the corresponding storage card slot 20, the corresponding insertion indicator light is on;Select the data to be burned and the target storage card slot 20 in the host computer software;Start the burning process, the data is transmitted to the system through the host computer signal interface 30, and then written into the Micro SD card by the multi-channel burning controller 50 in parallel, and the read-write indicator light flashes during the burning process, indicating the data transmission state.After burning, the read-write indicator light is always on, indicating that the burning is successful.

[0088] Repeat the above steps until all Micro SD cards are burned.
