For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] The present application relates to an image processing board and an image processing device. Figure 1-2 As shown, the image processing board includes: a power supply switching circuit 10, a micro switch 20, an erasing module 30 and an embedded control module 40, and the embedded control module 40 is electrically connected to the power supply switching circuit 10, the micro switch 20 and the erasing module 30 respectively; it can achieve a good electrical connection effect, thereby ensuring a good electrical signal transmission effect between modules.

[0032] The power supply switching circuit 10 is used for power supply and power switching, so that the embedded control module 40 can operate normally; and can achieve good power supply and power switching effects.

[0033] The micro switch 20 detects the low level state and feeds back the low level state to the embedded control module 40. The embedded control module 40 sends a control signal according to the fed-back low level state to control the action of the erasing module 30 so that the image processing board is powered on and runs the erasing instruction.

[0034] Specifically, one end of the micro switch 20 is connected to the erase signal in the image processing board, and the other end is connected to the signal ground in the image processing board. At this time, when the micro switch 20 is closed, the signal is a low level, and when it is disconnected, it is a high level signal.

[0035] The micro switch 20 is initially in the disconnected state, and the erase signal on the image processing board is at a high level. If there is a disassembly action, the micro switch 20 is closed and the erase signal is at a low level. After the image processing board receives the low level signal, the system program starts to erase.

[0036] The erase signal is monitored by the embedded control module 40 (MCU) in the image processing board. The MCU is powered by TypeC and a battery. The MCU works when either of the two power supplies is powered. In both power supply states, the MCU can erase when it detects that the erase signal is in a low level state.

[0037] It should be noted that the embedded control module 40 (Microcontroller Unit, MCU) is a microcomputer system that integrates functions such as a processor core, memory, input and output interfaces, and timers, etc. It is usually used to control operations in various electronic devices and systems and is one of the core components of embedded systems.

[0038] The main components include: Processor core: Usually a microprocessor such as the ARM Cortex-M series, which is used to execute programs and control logic.

[0039] The memory includes, but is not limited to: Flash Memory: used to store program code. RAM (Random Access Memory): used to store runtime data and temporary variables. EEPROM (Electrically Erasable Programmable Read-Only Memory): used to store non-volatile data, such as configuration settings and calibration data.

[0040] Input and output interfaces include but are not limited to: Digital input and output (GPIO): used to connect external sensors, actuators and other devices. Analog input and output (ADC / DAC): used to collect and output analog signals. Serial communication interface (UART, SPI, I2C, etc.): used to communicate with other devices. Timers and counters: used to generate precise time delays, pulse width modulation (PWM) and event counting. Clock and power management unit: provides clock source and power management functions to ensure system stability and power consumption optimization.

[0041] From the above description, it can be seen that the present application achieves the following technical effects:

[0042] In the embodiment of the present application, a micro switch 20 and a power supply switching circuit 10 are added, and a low level state is detected by the micro switch 20, and the low level state is fed back to the embedded control module 40. The embedded control module 40 sends a control signal according to the fed-back low level state to control the action of the erasing module 30, so that the image processing board is powered on and runs the erasing instruction, thereby achieving the purpose of automatic detection and control, thereby realizing the technical effect that the system can run the erasing instruction by itself, and further solving the problem in image processing applications, especially involving sensitive data or scenarios with high security requirements, that the data stored in the device needs to be automatically erased when the device is illegally disassembled to prevent data leakage. The current common solution is to achieve data erasure through software or complex hardware circuits, but these methods are often costly and complex to implement; and the image processing board cannot obtain a reliable power supply system, resulting in a technical problem that its normal operation cannot be guaranteed.

[0043] Further, the power supply switching circuit 10 includes: a power supply unit and a power switching unit, and the power supply unit and the power switching unit are electrically connected to the embedded control module 40 respectively;

[0044] The embedded control module 40 sends control signals to control the power supply unit and the power switching unit according to the detection signals detected and fed back by the power detection unit. It can be understood that stable power supply and power switching effects can be achieved.

[0045] Further, the power supply unit includes: a Type C power supply 101 and a battery power supply 102, and the Type C power supply 101 and the battery power supply 102 are respectively electrically connected to the embedded control module 40. It can be understood that a plurality of power supply modes can be implemented to ensure the normal operation of the embedded control module 40.

[0046] like Figure 3 As shown, the power supply switching circuit 10 uses a TPS2121 chip for two inputs and one output. It is understandable that the use of the TPS2121 chip has functions including but not limited to the following: Power selection and switching: TPS2121 can automatically select two different power inputs (such as the main power supply and the backup power supply) and switch when necessary to ensure continuous power supply of the device.

[0047] Low voltage drop switches: have low resistance switching characteristics that enable fast switching between power sources, minimizing power consumption and voltage drops when switching between power sources.

[0048] Overvoltage protection: It can provide overvoltage protection for the input power supply and protect the circuit from abnormal voltage.

[0049] Thermal shutdown protection: In overload or overheating conditions, the TPS2121 can automatically shut down the output to protect devices and circuits.

[0050] Small packages: Often available in small packages (such as QFN packages) to facilitate integration and layout in compact circuit board designs.

[0051] Low power design: Suitable for applications requiring low power consumption and efficient energy management, such as portable devices and battery-powered 102 systems.

[0052] Those skilled in the art should be familiar with the electrical schematic diagram of the TPS2121 chip.

[0053] Furthermore, when the power detection unit detects that the Type C power supply 101 is powered, the embedded control module 40 sends a control signal to turn off the battery power supply 102 and control the Type C power supply 101, so that the image processing board is in a normal working mode and all functional modules are powered on normally.

[0054] Further, when the power detection unit detects that the Type C power supply 101 is powered off, the embedded control module 40 sends a control signal to turn off the Type C power supply 101 and control the battery power 102 to the embedded control module 40 on the image processing board.

[0055] Specifically, the MCU in the image processing board monitors the TypeC power supply. When the TypeC power supply has power, the internal small battery is turned off to power the image processing board. The TypeC power supply is used to power 101. The image processing board works in normal mode and all functional modules are powered on normally. When the MCU detects that the TypeC has no power, the TypeC power supply is turned off and the internal small battery is selected to power the image processing board. At this time, the image processing board turns off all power supplies except the MCU. When the erase signal is detected, the MCU powers on the image processing board and the system starts to erase.

[0056] Furthermore, the micro switch 20 is a normally open micro switch 20. It is understandable that the normally open micro switch 20 is an electrical switch, which is usually used to control the current flow state in a circuit. When it is not pressed or triggered, it is in an open state (i.e., the circuit is not conducting), and when it is pressed or triggered, the switch is closed (i.e., the circuit is conducting).

[0057] The present application also relates to an image processing device, comprising the image processing board as described above.

[0058] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical scheme of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
