[0002] The power station data acquisition system is a key technical system for real-time monitoring and management of the operation state of the power station. It usually includes multiple subsystems, such as a data acquisition communication subsystem, a data processing and human-machine contact subsystem, a remote communication subsystem, and a time synchronization subsystem. These subsystems work together to ensure efficient, safe, and reliable operation of the power station. For some distributed power stations, the power station data acquisition system is usually set in an industrial personal computer located outside the distributed power station, so as to realize data acquisition, forwarding, and control of power equipment inside the power station. However, the external working environment is relatively harsh, especially in the summer when the temperature is high. The temperature of the industrial personal computer rises rapidly and easily reaches the upper limit of the working temperature, causing the industrial personal computer to run abnormally or even crash.

[0003] The prior art generally expands the hardware structure of the industrial personal computer to improve its heat dissipation, such as replacing or adding new heat exchange equipment. This improvement method has high cost and occupies a large volume. SUMMARY

[0064] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0065] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0066] This invention provides a control method for an industrial control computer (ICC), applicable to situations where the internal ambient temperature of the ICC is high, requiring heat dissipation and cooling. This method can be executed by a control device integrated within the ICC. Figure 1 A flowchart illustrating a control method for an industrial control computer provided in an embodiment of the present invention. (See reference) Figure 1 The method includes:

[0067] S110: Obtain the internal ambient temperature of the industrial computer and the operating parameters of at least two functional control units of the industrial computer.

[0068] Different functional control units control the industrial computer to perform various functions. These control units work together to enable the industrial computer to monitor and manage the power station. The temperature rise of the industrial computer is mainly caused by the heat generated by each functional control unit during operation; the higher the operating frequency of the functional control unit, the more heat it generates. When the internal temperature of the industrial computer becomes too high, it indicates that the functional control unit is operating at a high frequency. If this frequency is not reduced in time, the heat generated will continue to rise due to the high operating frequency, potentially burning out some functional control units and causing the industrial computer to malfunction.

[0069] By detecting the internal ambient temperature of the industrial control computer, it can be determined whether the computer needs heat dissipation or cooling. The operating parameters of the function control unit can characterize its operating status, such as its power consumption, data processing volume, and decoding rate.

[0070] This step can be performed by the data acquisition module.

[0071] S120. When the industrial control computer is determined to be in the primary warning mode based on the internal ambient temperature, the redundancy rate of each functional control unit is calculated based on the operating parameters of each functional control unit; wherein, the redundancy rate is used to reflect the ineffective power consumption of each functional control unit.

[0072] The primary warning mode indicates that the internal ambient temperature of the industrial control computer (ICC) is about to reach its rated operating temperature limit. If the temperature reaches the upper limit and remains there for an extended period, the ICC will malfunction due to overheating and may even fail. Therefore, when the primary warning mode is reached, cooling measures are needed to lower the internal ambient temperature of the ICC. Specifically, the redundancy rate of each functional control unit is calculated. This redundancy rate identifies which functional control units are consuming unnecessary power. By adjusting the redundancy rate of each functional control unit, the power consumption of each unit can be adaptively reduced to minimize unnecessary losses and reduce heat generation, thereby lowering the internal ambient temperature of the ICC.

[0073] This step can be performed by the data acquisition module.

[0074] S130. Based on the redundancy rate of each functional control unit, generate the frequency reduction amount for each functional control unit, and control the corresponding functional control unit to reduce its operating frequency based on the frequency reduction amount.

[0075] By independently calculating the frequency reduction amount for each functional control unit, the operating frequency of the corresponding functional control unit can be reduced according to the frequency reduction amount. For example, when the redundancy rate of a functional control unit is 30%, the operating frequency of that functional control unit is reduced by a certain amount according to the 30% redundancy rate; when the redundancy rate of another functional control unit is 40%, the operating frequency of that functional control unit is reduced by a certain amount according to the 40% redundancy rate.

[0076] This step can be performed by the analysis and control module.

[0077] Current technologies for cooling industrial PCs typically address the issue by increasing the size of the heatsink or the heatsink itself, or by employing active cooling methods such as adding fans or water cooling. These approaches require additional cooling equipment, thus occupying significant internal space within the industrial PC. Furthermore, the installation of this cooling equipment is complex, leading to unnecessary increases in labor and equipment costs.

[0078] The technical solution provided by this invention calculates the redundancy rate of each functional control unit in the primary warning mode, and can generate independent frequency reduction amounts for each functional control unit in a targeted manner, and control the frequency reduction of each functional control unit according to the frequency reduction amount. This setting method has high controllability, achieves independent adjustment of each functional control unit, and performs frequency reduction according to the redundancy rate of each functional control unit, which can achieve a good frequency reduction effect while ensuring the normal operation of the industrial control computer. Therefore, this invention helps to avoid affecting the normal operation of each functional control unit by directly adjusting the frequency of each functional control unit with a fixed value. Furthermore, the heat dissipation control method provided by this invention through frequency adjustment of each functional control unit can be implemented in software in the main controller without adding new heat dissipation equipment, thus having a smaller size and helping to avoid unnecessary increases in equipment costs.

[0079] Based on the above embodiments, optionally, controlling the corresponding functional control unit to reduce its frequency includes: obtaining the adjustment granularity and determining the frequency reduction gradient based on the adjustment granularity. Based on the frequency reduction gradient, controlling the corresponding functional control unit to gradually reduce its operating frequency.

[0080] The adjustment granularity can be set by the user as needed, and the frequency reduction gradient is used to represent the degree of frequency reduction. A larger adjustment granularity results in a larger frequency reduction gradient and a better frequency reduction effect; a smaller adjustment granularity results in a smaller frequency reduction gradient and a more stable frequency reduction process. By reducing the frequency of each functional control unit with a certain gradient, sudden frequency changes during the frequency reduction process can be prevented, thus avoiding instability in the functional control unit. Therefore, this embodiment of the invention makes the frequency reduction process smoother, preventing the functional control units from being impacted by sudden frequency changes, and thus ensuring high reliability.

[0081] Based on the above embodiments, optionally, the industrial control computer can be divided into different control modes, including a primary warning mode, according to the internal ambient temperature. In one embodiment, the control modes include:

[0082] Normal mode: The internal ambient temperature in normal mode is lower than that in the initial warning mode.

[0083] Warning mode: The internal ambient temperature in warning mode is between that in normal mode and primary warning mode.

[0084] Primary warning mode: The internal ambient temperature in primary warning mode is between that in early warning mode and secondary warning mode.

[0085] Level 2 warning mode: The internal ambient temperature corresponding to Level 2 warning mode is higher than that of Level 1 warning mode.

[0086] In normal mode, the monitoring frequency for internal ambient temperature and operating parameters of each functional control unit is the first frequency; in early warning mode, primary warning mode and secondary warning mode, the monitoring frequency for internal ambient temperature and operating parameters of each functional control unit is the second frequency; the second frequency is higher than the first frequency.

[0087] In the normal mode, the internal ambient temperature of the industrial control computer is within a relatively safe operating environment. In this mode, redundancy calculations are unnecessary, and frequency reduction of individual functional control units is not required. Therefore, in this mode, the internal ambient temperature and operating parameters of each functional control unit can be monitored at a lower monitoring frequency. The normal mode can be stored in the normal mode model.

[0088] When the internal ambient temperature rises to near the level of the primary warning mode, the industrial control computer enters warning mode. This mode indicates that the internal ambient temperature is high, but this temperature will not affect the normal operation of the industrial control computer. If the temperature continues to rise, it may affect the operation of the industrial control computer. Therefore, in this state, it is necessary to increase the monitoring frequency of the internal ambient temperature so that a timely response can be received when the internal ambient temperature reaches the primary warning mode. The warning mode can be stored in the warning mode model.

[0089] When the internal ambient temperature continues to rise to the level of the primary warning mode, the industrial control computer enters primary warning mode. This mode indicates that the industrial control computer is in a relatively high-temperature operating environment, and if it is not cooled in time or the cooling effect is ineffective, the temperature may continue to rise. In this state, it is necessary to calculate the redundancy rate of each functional control unit based on its operating parameters. Then, based on the redundancy rate of each functional control unit, the corresponding functional control unit is controlled to reduce its frequency for cooling. The primary warning mode can be stored in the primary warning mode model.

[0090] When the internal ambient temperature continues to rise and exceeds the primary warning mode, the industrial PC enters the secondary warning mode. This mode indicates that the frequency reduction strategy in the primary warning mode is insufficient to effectively lower the internal ambient temperature. If the industrial PC maintains a sustained high temperature, it may damage its internal functional control units or other electronic components. For example, when the industrial PC enters the secondary warning mode, it can reduce the operating frequency of each functional control unit to the minimum operating frequency, minimizing the heat generated by each functional control unit and thus lowering the internal ambient temperature. The secondary warning mode can be stored in a secondary warning mode model.

[0091] In the above embodiments, the basis for determining which control mode the industrial control computer is in is the internal ambient temperature. The higher the internal ambient temperature, the higher the warning level of the control mode, in the order of normal mode, early warning mode, primary warning mode and secondary warning mode.

[0092] Optionally, the industrial control computer is in normal mode as determined by the internal ambient temperature, specifically including: the difference between the upper limit of the rated operating temperature of the industrial control computer and the internal ambient temperature is greater than a first temperature threshold.

[0093] The industrial control computer is in a warning mode based on the internal ambient temperature. Specifically, this includes situations where the difference between the rated operating temperature limit of the industrial control computer and the internal ambient temperature is less than or equal to the first temperature threshold.

[0094] The industrial control computer is in a primary warning mode based on the internal ambient temperature. Specifically, this includes situations where the difference between the rated operating temperature limit of the industrial control computer and the internal ambient temperature is less than or equal to the second temperature threshold.

[0095] The industrial control computer is in a level 2 warning mode based on the internal ambient temperature, specifically when the internal ambient temperature reaches the upper limit of the industrial control computer's rated operating temperature.

[0096] The first temperature threshold is greater than the second temperature threshold. Normal mode, early warning mode, primary warning mode, and secondary warning mode each correspond to different internal ambient temperatures. For example, the upper limit of the rated operating temperature can be set to 70 degrees Celsius, the first temperature threshold can be set to 30 degrees Celsius, and the second temperature threshold can be set to 10 degrees Celsius. The industrial computer's normal mode operates within an internal ambient temperature range below 40 degrees Celsius; its early warning mode operates within an internal ambient temperature range of 40-60 degrees Celsius; its primary warning mode operates within an internal ambient temperature range of 60-70 degrees Celsius; and its secondary warning mode operates within an internal ambient temperature range greater than or equal to 70 degrees Celsius. By defining different first and second temperature thresholds, the industrial computer can be divided into different adjustment modes, allowing it to execute different cooling methods in different modes, providing high flexibility and controllability.

[0097] Based on the above embodiments, the control method of the industrial control computer may optionally include: in the secondary warning mode, controlling the operating frequency of the functional control unit in the industrial control computer to be lower than the minimum operating frequency in the primary warning mode.

[0098] If the frequency reduction strategy in the primary warning mode fails to effectively lower the internal ambient temperature of the industrial control computer, the temperature will rise to the secondary warning mode. In this mode, the primary task is to ensure the safe operation of the industrial control computer. Therefore, the minimum operating frequency of each functional control unit can be obtained and directly reduced to that minimum. For example, the operating frequency of each functional control unit can be controlled to a frequency sufficient to perform only its basic functions. This setting allows each functional control unit to operate at an extremely low frequency, resulting in lower heat generation and effectively reducing the internal ambient temperature.

[0099] Based on the above embodiments, optionally, the control method of the industrial control computer further includes: if the industrial control computer remains in the second-level warning mode after a set time, then the industrial control computer is controlled to stop.

[0100] When the industrial control computer remains in level two warning mode and cannot be switched to other modes after the set time, it may be due to the various functional control units of the industrial control computer operating at high frequency for an extended period, or it may be due to high ambient temperature or direct sunlight exposure. In this case, the temperature of the industrial control computer may not be effectively reduced in a short period of time. To ensure the safe operation of the industrial control computer, it can be shut down and restarted after the internal ambient temperature has decreased. Optionally, before shutting down, the industrial control computer will save the current operating data to prevent data loss and ensure the security of the operating data.

[0101] This step can be performed by the timed shutdown module.

[0102] Based on the above embodiments, optionally, the functional control unit includes at least one of a central control unit, a programmable unit, a communication unit, and an embedded neural processing unit.

[0103] The system includes a central control unit (CPU) for controlling the industrial computer to execute system commands. The programmable unit (CPLD) is used to execute different control algorithms according to different functions and may include a CPLD. The communication unit primarily handles network communication and may include a 4G communication module. The embedded neural processing unit (NPU) is used to decode image data and may include a neural processing unit (NPU).

[0104] Based on the above embodiments, the calculation method for redundancy rate varies for different functional control units.

[0105] In one implementation, optionally, for the central control unit, the redundancy rate of each functional control unit is calculated based on the operating parameters of each functional control unit, including: obtaining the overall utilization rate of the central control unit, where the overall utilization rate is the ratio of the operating power of the central control unit to the total power of the central control unit. The redundancy rate of the central control unit is then determined based on the overall utilization rate.

[0106] The overall utilization rate of the central control unit (CCU) can be defined as the ratio of its operating power to its maximum operating power, where maximum operating power is the total power of the CCU. The more system commands the CCU executes, the higher its operating power. Therefore, the overall utilization rate of the CCU can be collected by acquiring system commands, and the redundancy rate of the CCU can be calculated.

[0107] Optionally, the redundancy rate of the central control unit is determined based on the overall utilization rate, including: determining the unutilized rate of the central control unit based on the overall utilization rate; and performing a linear transformation on the unutilized rate to obtain the redundancy rate of the central control unit.

[0108] Directly reducing the frequency of the central control unit (CCU) based on its overall utilization rate could negatively impact its normal operation. Therefore, to obtain an accurate reduction, the unutilized rate of the CCU can be calculated from its overall utilization rate, and then converted into a redundancy rate using a linear relationship. The CCU's frequency is then reduced based on this redundancy rate. For example, if the overall utilization rate of the CCU is 40%, the unutilized rate is 60%. If an 80% linear relationship is set at this point, the redundancy rate is 48%.

[0109] In one embodiment, optionally, for the programmable unit, calculating the redundancy rate of each functional control unit based on the operating parameters of each functional control unit further includes: obtaining the output frequency of the programmable unit and a first required frequency; the first required frequency is the minimum value of the required frequency range of the programmable unit. The redundancy rate of the programmable unit is determined based on the output frequency and the minimum required frequency.

[0110] The higher the output frequency of a programmable unit, the greater its workload and the higher its operating frequency, resulting in greater heat generation. If the output frequency of a programmable unit is greater than the minimum value of its required frequency range, it indicates that the programmable unit has frequency redundancy, and even if the frequency is reduced, the normal operation of the programmable unit can still be guaranteed.

[0111] Based on the above embodiments, optionally, the redundancy rate of the programmable unit is determined according to the output frequency and the minimum required frequency, including: obtaining the computing power redundancy rate of the programmable unit according to the output frequency and the minimum required frequency, wherein the difference between the output frequency and the minimum required frequency is related to the computing power redundancy rate; and converting the computing power redundancy rate into the redundancy rate of the programmable unit according to a conversion factor.

[0112] For example, the computing power redundancy rate can be: (current output frequency - first required frequency) / maximum output frequency. Since the computing power redundancy rate represents the computing power redundancy of the programmable unit, it needs to be converted into the redundancy rate of the programmable unit according to the conversion factor in order to adjust the frequency. Specifically, the computing power redundancy rate is directly proportional to the redundancy rate of the programmable unit; the higher the computing power redundancy rate, the higher the redundancy rate of the programmable unit.

[0113] In one embodiment, optionally, for the communication unit, calculating the redundancy rate of each functional control unit based on the operating parameters of each functional control unit further includes: acquiring the data output quantity of the communication unit within one cycle and a first data output quantity; the first data output quantity is the maximum value among the data output quantities of the communication unit. The redundancy rate of the communication unit is determined based on the data output quantity and the first data output quantity.

[0114] The maximum data output is the maximum rated output of the communication unit within one cycle. The redundancy rate of the communication unit can be calculated as: data output / maximum rated output. Generally, the maximum rated output is a fixed parameter of the communication unit, and different communication units have different maximum rated output values. In other words, the larger the data output, the greater the redundancy rate of the communication unit, and the more energy it consumes.

[0115] In one embodiment, optionally, for the embedded neural processing unit, the redundancy rate of each functional control unit is calculated based on the operating parameters of each functional control unit, and the method further includes: obtaining the decoding rate of the embedded neural processing unit and the rated decoding rate of the embedded neural processing unit; the rated decoding rate is a requirement parameter of the embedded neural processing unit. The redundancy rate of the embedded neural processing unit is determined based on the decoding rate and the requirement parameter.

[0116] The higher the decoding rate of the embedded neural processing unit (NNUnit), the higher its operating frequency, and the more heat it generates. The redundancy rate of the NNUnit can be calculated as: (decoding rate - required parameters) / required parameters. If the decoding rate of the NNUnit is greater than its required parameters, it indicates a higher decoding rate and therefore a higher redundancy rate. This redundancy rate can be reduced by decreasing the operating frequency of the NNUnit.

[0117] Figure 2 A flowchart illustrating another industrial control computer control method provided in an embodiment of the present invention. (See reference...) Figure 2 Based on the above embodiments, optionally, in step S130, the frequency reduction amount of each functional control unit is generated according to the redundancy rate of each functional control unit, and the corresponding functional control unit is controlled to reduce its operating frequency based on the frequency reduction amount, including:

[0118] S131. Based on the redundancy rates of the central control unit, programmable unit, communication unit, and embedded neural processing unit, generate the frequency reduction amount of the central control unit, programmable unit, communication unit, and embedded neural processing unit, respectively.

[0119] To achieve frequency control of each functional control unit, the redundancy rate of each functional control unit can be calculated, and the corresponding frequency reduction amount can be generated based on the redundancy rate of each functional control unit.

[0120] S132. Based on the frequency reduction priority settings of the central control unit, programmable unit, communication unit, and embedded neural processing unit, control each functional control unit to reduce the frequency sequentially in descending order of the set frequency reduction priority.

[0121] When reducing the frequency based on the amount of frequency reduction, the frequency can be reduced sequentially according to the set frequency reduction priority. For example, the central control unit (CCU) is the core control unit of the industrial computer, and its reliable operation is crucial. Therefore, its frequency reduction priority is set to the lowest. The communication unit has a smaller impact on the industrial computer's functionality, so its frequency reduction priority is set higher than that of the CCU. When reducing the frequency, the communication unit must be reduced first. After reducing its frequency, if the internal ambient temperature can be lowered to normal or warning mode, there is no need to reduce the frequency of the CCU. If the temperature does not drop to normal or warning mode, the CCU continues to be reduced. By setting the frequency reduction priority, the impact on the industrial computer's operation can be reduced during the frequency reduction process.

[0122] This step can be performed by the frequency reduction strategy module.
