[0028] When the main power is turned on, if the protection circuit setting value is met, the SOM will be powered on.

[0029] The SOM board will output 3.3V to enable the peripheral circuits to start powering on.

[0030] After the peripheral circuit is powered, it is also controlled by the enable port of the SOM core board, which can control the power consumption of the device according to the application scenario.

[0031] By setting the power supply to start according to a set sequence, surge protection of the equipment can be avoided, thus ensuring the stability of the correct power supply.

[0032] Supports 6 are fixedly installed at the four corners of the bottom of the acquisition box body 1. The heat dissipation mechanism 5 consists of a copper heat-conducting plate 7, a heat pipe 8, a turbine centrifugal fan 9, and an L-shaped cover plate 10. The heat pipe 8 and the turbine centrifugal fan 9 are installed inside the acquisition box body 1. The copper heat-conducting plate 7 is fixedly connected to one end of the bottom of the heat pipe 8. The bottom surface of the copper heat-conducting plate 7 is in contact with the top surface of the chip 4. Thermal grease is filled between the copper heat-conducting plate 7 and the chip 4. The other end of the heat pipe 8 passes through the exhaust port of the turbine centrifugal fan 9. The L-shaped cover plate 10 passes through... The screw is connected to one end of the collection box body 1 and fits against the air inlet and outlet of the turbine centrifugal fan 9. The heat pipe 8 is composed of an evaporation section 11 and a condensation section 12. The evaporation section 11 is connected to the copper heat conduction plate 7. The condensation section 12 passes through the air outlet of the turbine centrifugal fan 9. Several heat dissipation fins 13 are fixedly installed on one end of the condensation section 12 near the turbine centrifugal fan 9. An air inlet 14 is opened at the bottom of the L-shaped cover plate 10. An air outlet 15 is opened on one side of the L-shaped cover plate 10.

[0033] During heat dissipation, the heat from chip 4 is transferred to copper heat-conducting plate 7. The contact gap is reduced by filling with thermal grease, which improves the heat conduction efficiency. The evaporation section 11 of heat pipe 8 absorbs heat, and the liquid inside evaporates and absorbs heat. The steam flows to the condensation section 12 and is dissipated by the turbine centrifugal fan 9. The steam condenses and dissipates heat. The condensed liquid flows back along the heat pipe 8, thus forming a circulating heat dissipation and improving the heat dissipation efficiency. The air inlet 14 and the air outlet 15 can cooperate with the turbine centrifugal fan 9 to realize air intake and exhaust.

[0034] In operation, the MX26631DL is configured to meet power protection functions, enabling a 4.5V to 40V, 5A electronic fuse function. Using back-to-back MOSFETs allows for bidirectional shutdown and provides overvoltage, undervoltage, short-circuit, current limiting, and reverse current blocking protection. By setting the power supply to start according to a predetermined sequence, surge protection can be avoided, ensuring a stable and accurate power supply. A heat dissipation mechanism consisting of a copper heatsink, heat pipes, a centrifugal fan, and an L-shaped cover plate enables efficient heat dissipation of the chip, preventing overheating that could affect operational stability and lifespan.
