[0051] In one specific embodiment, the power supply module comprises a power supply circuit and a protection circuit.

[0052] The power supply circuit and the protection circuit are connected with the master control unit respectively.

[0053] Specifically, the power supply circuit is connected with an external power supply, and the power supply can be in various forms. The power supply module of the utility model supports various power supply modes, including a battery, solar charging and external DC power input, and is internally provided with a protection circuit.

[0054] Specifically, the power supply circuit is responsible for providing stable and reliable power support for the entire device. It includes:

[0055] The rectifier converts alternating current into direct current. Commonly used are bridge rectifiers.

[0056] The input filter is used to remove noise and transient interference in the power grid to prevent these disturbances from entering the subsequent circuit.

[0057] The output filter smoothes the pulsating direct current after rectification and provides purer direct current to the load.

[0058] The voltage stabilizer is used to ensure that the output voltage is constant and is not affected by input voltage fluctuations. Common voltage stabilization methods include linear voltage stabilizers and switch mode power supplies (SMPS). SMPS has higher efficiency but relatively complex structure; linear voltage stabilizers are simple and reliable, suitable for small current applications.

[0059] Specifically, the protection circuit is a series of measures designed to prevent safety hazards caused by electrical faults. It mainly includes the following types:

[0060] Overvoltage protection (OVP), when the input voltage exceeds the set threshold, automatically cuts off the power input to avoid damaging sensitive components. It can be realized by using special IC or simple Zener diode.

[0061] Under-voltage lockout (UVLO), prevents the system from starting until the input voltage is below a certain level, preventing operation under unstable voltage conditions and protecting internal circuits from damage.

[0062] Overcurrent protection (OCP), detects and limits the output current to a safe limit to prevent excessive current damage to the circuit caused by short circuits or other abnormal conditions. It can be realized by using a fuse, PTC thermistor or intelligent power management chip.

[0063] Short circuit protection, in response to possible short circuit conditions, quickly disconnects the power supply connection to ensure that no fire or other serious consequences will occur due to continuous high current.

[0064] Reverse voltage protection, to prevent damage caused by incorrect insertion of power plugs or reversed polarity of batteries. The common method is to install a Schottky diode or MOSFET at the power inlet.

[0065] Electrostatic discharge (ESD) protection, ESD protection devices are installed in places susceptible to static shock, such as interface pins, to absorb transient high voltage and protect internal circuits from damage.

[0066] Temperature protection, monitor the temperature of key parts, and take cooling measures (such as fan control) when the temperature is too high, or even shut down the power supply to prevent overheating damage.

[0067] Surge protection, using MOV (metal oxide varistor), gas discharge tube and other components to absorb transient high voltage surges from the power grid, protecting the back-end circuit from damage.

[0068] Specifically, the efficient and safe power supply module and energy-saving design prolong the working life of the device and reduce maintenance costs.

[0069] In one embodiment, the housing adopts a sealed structure, and specifically, according to the requirements of the application scene, a suitable IP protection level is selected, such as IP67 or higher standards, to ensure complete protection against dust and the ability to be immersed in water for a short time without damage.
