[0076] In this embodiment, the air cooling unit includes:
[0077] The temperature monitoring module is used to install temperature sensors on the surface of the laser and key components, collect temperature data of the laser and key components in real time through the temperature sensors, and compare the temperature data with the preset temperature threshold to determine whether the temperature of the laser and key components is normal;
[0078] The heat dissipation control module is used to start the air-cooling heat dissipation system when the temperature data exceeds the preset threshold, cool the laser and key components through the heat dissipation fan, and monitor the temperature change data until the temperature drops to a safe range.
[0079] In this embodiment, the temperature data of the laser and key components are monitored in real time based on the installed temperature sensors. When the temperature exceeds the set threshold, heat is dissipated based on air cooling, and temperature feedback data is obtained to determine whether the temperature of the laser and key components is within the normal working range, thereby preventing overheating damage and ensuring that the equipment can continue to operate stably in a high temperature environment.
[0080] Specifically, the heat dissipation control module includes:
[0081] The indicator temperature data acquisition module is used to retrieve the temperature data corresponding to the preset threshold value as the indicator temperature data when the temperature data exceeds the preset threshold value;
[0082] A reference temperature data acquisition module is used to extract temperature data from historical operation records as reference temperature data;
[0083] A starting speed acquisition module, used to acquire the starting speed of the cooling fan when it is started according to the index temperature data and the reference temperature data;
[0084] The starting speed of the cooling fan when it is started is obtained by the following formula:
[0085]
[0086] Among them, N s Indicates the starting speed of the cooling fan when it is started; N c represents the preset initial reference value of the speed; n represents the number of reference temperature data; T i represents the temperature value corresponding to the i-th reference temperature data; T i+1 Indicates the temperature value corresponding to the i+1th reference temperature data; T b Indicates the standard deviation of the temperature values corresponding to n reference temperature data; T x Indicates the temperature value corresponding to the indicator temperature data; T e Indicates the temperature data obtained in the previous data collection corresponding to the index temperature data; T y Indicates the preset threshold corresponding to the temperature data; T max Indicates the maximum value of the temperature data corresponding to the reference temperature data;
[0087] The speed adjustment module is used to monitor the cooling speed of the indicator temperature data in real time, and adjust the speed of the cooling fan in real time according to the cooling speed.
[0088] The technical effect of the above technical solution is: through the index temperature data acquisition module, the key temperature data can be accurately obtained when the temperature exceeds the preset threshold, which helps the system to respond to temperature anomalies in a timely manner, thereby avoiding possible damage caused by overheating. The reference temperature data acquisition module uses the temperature data in the historical operation record, which helps the system understand the temperature change trend in the past and provide a more accurate reference for the startup speed of the cooling fan. Through the formula, the system can calculate a more reasonable startup speed by comprehensively considering multiple historical temperature data points, the standard deviation of the temperature data, the maximum temperature value, and the index temperature data at the current and previous moments, which reflects the intelligent decision-making ability based on historical data. The speed adjustment module can dynamically adjust the speed of the cooling fan according to the cooling speed monitored in real time, which means that the system can respond flexibly according to the actual situation, neither over-consuming energy nor putting the equipment at risk of overheating. Through the combined effect of the above modules, the system can control the temperature more effectively, reduce equipment failures or performance degradation caused by overheating, thereby improving the stability and reliability of the entire system. Dynamic adjustment of the speed of the cooling fan means that the system can adjust energy consumption according to actual needs and avoid unnecessary energy waste, which is of great significance for improving energy efficiency. Through sophisticated temperature control and dynamic adjustment strategies, the system can maintain the optimal operating state of the device, reduce performance fluctuations or failures caused by overheating, and thus improve the user experience.
[0089] In summary, this technical solution achieves many technical effects in terms of the performance indicators of the heat dissipation control module, such as precise temperature control, intelligent decision-making based on historical data, dynamic speed adjustment, improved system stability and reliability, optimized energy use, and enhanced user experience.
[0090] Specifically, the speed adjustment module includes:
[0091] A cooling speed monitoring module, used to monitor the cooling speed of the indicator temperature data in real time;
[0092] A speed keeping control module, used for keeping the current speed of the cooling fan at the starting speed when the index temperature data drops to no less than a preset threshold at the end of a preset time period after the cooling fan is started;
[0093] The observed temperature data acquisition module is used to retrieve the temperature value corresponding to the end of the preset time period as the observed temperature data when the index temperature data still exceeds the preset threshold at the end of the preset time period after the cooling fan is started;
[0094] A speed data acquisition module, used to adjust the speed of the cooling fan using the observed temperature data and the index temperature data to obtain the adjusted speed, wherein the index temperature data is the temperature data corresponding to the temperature exceeding the preset threshold;
[0095] The adjusted speed is obtained by the following formula:
[0096]
[0097] Among them, N t Indicates the adjusted speed; N s Indicates the starting speed of the cooling fan when it is started; T x Indicates the temperature value corresponding to the indicator temperature data; T y Indicates the preset threshold corresponding to the temperature data; T g represents the observed temperature data; t represents the duration corresponding to the preset time period; T fmax Indicates the maximum floating value of the temperature data corresponding to each two adjacent temperature collections in the preset time period; T fj represents the floating value of the temperature data of the jth temperature collection in the preset time period relative to the corresponding previous temperature collection; m represents the number of temperature data collections in the preset time period; T j Indicates the temperature value corresponding to the jth temperature data collection within the preset time period; T j+1 Indicates the temperature value corresponding to the j+1th temperature data collection within the preset time period;
[0098] The speed adjustment control module is used to control the operation of the cooling fan according to the adjusted speed.
[0099] The technical effect of the above technical solution is that the cooling speed monitoring module can monitor the cooling speed of the index temperature data in real time, which ensures the system's ability to respond quickly to temperature changes and helps to adjust the heat dissipation strategy in time. When the heat dissipation fan is started within a preset time period, if the index temperature data drops to no more than the preset threshold, the speed maintenance control module will keep the current heat dissipation fan speed at the startup speed. This strategy helps to maintain the stability of the system when the temperature is effectively controlled, while avoiding unnecessary energy consumption. When the index temperature data still exceeds the preset threshold within the preset time period, the observation temperature data acquisition module will obtain the observation temperature data, and use these data to adjust the speed through the speed data acquisition module. This strategy ensures that the system can flexibly adjust the speed of the heat dissipation fan when the temperature continues to be high to more effectively reduce the temperature. The speed adjustment formula takes into account multiple factors, including the startup speed, the index temperature data, the preset threshold, the observation temperature data, the duration corresponding to the preset time period, the maximum value of the temperature data floating, and the number of temperature data collection times within the preset time period. This adjustment method that comprehensively considers multiple parameters can more accurately reflect the actual heat dissipation needs of the system, thereby providing more accurate speed adjustment. By controlling the cooling fan to run at the adjusted speed through the speed adjustment control module, the system can more effectively control the temperature and reduce equipment failure or performance degradation caused by overheating. This helps to improve the stability and reliability of the entire system. The flexible speed adjustment strategy means that the system can adjust the speed of the cooling fan according to actual needs, thereby avoiding unnecessary energy waste. This helps to reduce the energy consumption of the system and improve energy efficiency. Through fine temperature control and speed adjustment strategies, the system can maintain the best operating state of the equipment and reduce performance fluctuations or failures caused by overheating. This helps to improve the user experience and enhance user satisfaction with the system.
[0100] In summary, this technical solution achieves many technical effects in terms of the performance indicators of the speed adjustment module, including real-time monitoring and response, stable speed maintenance, flexible speed adjustment, precise adjustment based on the above formula, efficient heat dissipation control, optimized energy use, and enhanced user experience.
