[0038] like Figure 1 As shown, this utility model provides an intelligent heat dissipation electronic bus stop sign system, including:

[0039] Temperature acquisition module 1 is used to collect the ambient temperature around the electronic bus stop sign in real time.

[0040] Heat dissipation module 2 is used to dissipate heat from the electronic bus stop sign;

[0041] The controller 3 is connected to the temperature acquisition module 1 and the heat dissipation module 2 respectively. It is used to receive the ambient temperature collected in real time by the temperature acquisition module 1 and compare the real-time ambient temperature with the preset temperature threshold to adjust the operating parameters of the heat dissipation module 2.

[0042] In the embodiments of this utility model, through the above-mentioned settings, the intelligent heat dissipation electronic bus stop system can control the operating parameters of the heat dissipation module 2 according to the environment around the electronic bus stop through intelligent temperature management and heat dissipation functions, so as to ensure that the electronic bus stop can maintain the best working state under different ambient temperatures.

[0043] Temperature acquisition module 1: Real-time acquisition of ambient temperature around the electronic bus stop sign; by sensing the ambient temperature, it provides the system with the necessary data support so that it can make corresponding adjustments according to changes in ambient temperature.

[0044] Heat dissipation module 2: This module dissipates heat from the electronic bus stop sign, ensuring it operates within a normal temperature range. By adjusting the heat dissipation efficiency, it prevents damage or performance degradation due to overheating. Specifically, heat dissipation module 2 may include heat dissipation components such as a cooling fan 21 and heat sinks. By adjusting parameters such as the speed of the cooling fan 21 and the area of ​​the heat sink, effective heat dissipation from the inside of the electronic bus stop sign is achieved.

[0045] Controller 3: As the "brain" of the system, controller 3 is responsible for receiving real-time ambient temperature data transmitted by temperature acquisition module 1 and comparing it with preset temperature thresholds. Based on the comparison results, controller 3 automatically adjusts the operating parameters of heat dissipation module 2, such as fan speed and heat sink area, to keep the electronic bus stop sign operating within a suitable temperature range.

[0046] This intelligent heat dissipation electronic bus stop system achieves real-time monitoring and intelligent heat dissipation of the ambient temperature around the electronic bus stop through the close collaboration of temperature acquisition module 1, heat dissipation module 2, and controller 3. This ensures stable operation and a long service life for the electronic bus stop in high-temperature environments. Simultaneously, through the intelligent adjustment and self-learning functions of controller 3, the system can automatically adjust its heat dissipation strategy according to environmental changes, improving the overall performance and energy efficiency of the system.

[0047] For example, when the ambient temperature is low, the controller 3 reduces the speed of the cooling fan 21 to reduce energy consumption and noise. When the ambient temperature is high, the controller 3 increases the speed of the cooling fan 21 to enhance the heat dissipation effect.

[0048] Furthermore, the controller 3 includes a microcontroller 31;

[0053] In this embodiment of the invention, when the real-time ambient temperature reaches a preset temperature threshold, the microcontroller 31 drives the cooling fan 21 to start working; when the temperature reaches the preset maximum temperature threshold of the cooling fan 21, the cooling fan 21 operates at full speed. As the ambient temperature changes, the microcontroller 31 dynamically adjusts the speed of the cooling fan 21 to maintain the ambient temperature within a safe range. If the ambient temperature continues to rise, the microcontroller 31 may increase the speed of the cooling fan 21 to enhance the heat dissipation effect; conversely, if the ambient temperature drops, the microcontroller 31 may reduce the speed of the cooling fan 21 to save energy, thereby maintaining the electronic bus stop sign within a suitable temperature range.

[0054] In this embodiment of the present invention, the storage module 4 is connected to the microcontroller 31 and is used to locally store the preset temperature threshold.

[0055] The microcontroller 31 controls the speed of the cooling fan 21 offline based on the preset temperature threshold stored in the storage module 4.

[0056] In this embodiment of the present invention, the storage module 4 is used to locally store preset temperature thresholds; these preset values ​​serve as the basis for the microcontroller 31 to control the speed of the cooling fan 21; when the system starts or resets, the microcontroller 31 reads the preset temperature thresholds from the storage module 4.
