[0002] Thermal power plants typically have multiple generating units, each with multiple production buildings. These buildings can be equipped with windows for ventilation. The main production equipment inside the buildings includes boilers, steam turbines, and generators. This equipment releases heat during operation; for example, the heat generated by fuel combustion in the boiler causes the water inside to condense into high-temperature steam. When the temperature inside the production buildings is high and cooling is required, windows need to be opened manually, which is costly in terms of labor and inefficient in terms of cooling efficiency.

[0016] If the temperature inside the plant is less than a predetermined second temperature threshold, and the determined target opening value is less than a predetermined second opening threshold, then the fan unit is adjusted to a stopped state, where the first temperature threshold is greater than the second temperature threshold, and the first opening threshold is greater than the second opening threshold.

[0034] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0035] The accompanying drawings are provided to further illustrate the present disclosure and form part of the specification. They are used together with the following detailed description to explain the present disclosure, but do not constitute a limitation thereof. In the drawings:

[0036] Figure 1 This is a flowchart of a factory heat dissipation method provided in an exemplary embodiment.

[0037] Figure 2 This is a block diagram of a factory heat dissipation device provided in an exemplary embodiment. Detailed Implementation

[0038] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0039] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0040] Figure 1 This is a flowchart illustrating a factory heat dissipation method provided in an exemplary embodiment. The factory is equipped with louvers. Figure 1 As shown, the method includes the following steps.

[0041] In step S101, meteorological parameters outside the factory building and the current opening value of the louvers are obtained.

[0042] Thermal power plants typically consist of multiple generating units, each comprising multiple production buildings. Meteorological parameters can be acquired using miniature weather instruments mounted on the roofs of these buildings. If multiple miniature weather instruments are installed, the average value of the meteorological parameters acquired from these instruments can be used to determine the final meteorological parameter. For example, rainfall can be a meteorological parameter. A louver consists of multiple adjustable slats; the opening degree of the louver is related to the opening angle of the slats.

[0043] In step S102, the target opening value of the venetian blinds is determined based on the acquired meteorological parameters.

[0044] The production equipment inside the factory is greatly affected by external meteorological parameters. For example, when severe weather occurs, if the opening value of the louvers is not adjusted in time according to the meteorological parameters, the production equipment may be at risk of damage. Therefore, it is necessary to adjust the opening value of the louvers in a timely and accurate manner. In step S102, after obtaining the meteorological parameters outside the factory, the target opening value of the louvers can be determined based on the obtained meteorological parameters.

[0045] Specifically, the target opening value of the venetian blinds corresponding to the acquired meteorological parameters can be found from a predetermined correspondence, and this correspondence is used as the determined target opening value. The correspondence includes the correspondence between meteorological parameters and target opening values.

[0046] 5G base stations can be set up within the premises of a thermal power plant, enabling 5G communication between various production equipment, thus shortening data transmission time and reducing control latency. For example, after determining the target opening value of a louver, the determined target opening value can be sent to the louver via 5G communication.

[0047] In step S103, the difference between the target opening value and the current opening value is determined.

[0048] After determining the target opening value of the blinds based on the acquired meteorological parameters, the difference between the current opening value and the determined target opening value can be determined. For example, if the current opening value is 30% and the determined target opening value is 40%, then the difference is determined to be 10%.

[0049] In step S104, based on the determined difference, the opening value of the venetian blinds is adjusted using a proportional-integral-differential (PID) algorithm so that the opening value of the venetian blinds reaches the target opening value.

[0050] PID control algorithm is a control algorithm that combines proportional, integral and derivative elements into one. It can effectively correct the deviation of the controlled object and achieve precise control.

[0051] After determining the difference, the target opening value of the blinds can be used as the setpoint for the PID algorithm, and the determined difference can be used as the input value for the PID algorithm. The PID algorithm controls the opening value of the blinds to gradually approach the target opening value over multiple adjustment cycles until the opening value is reached. Within each adjustment cycle, the blind opening value output by the PID algorithm can be used as the data basis for the next adjustment cycle. That is, the difference between the blind opening value output in that cycle and the target opening value (the setpoint for the PID algorithm) is used as the input value for the next adjustment cycle. The setpoint for the PID algorithm remains unchanged within each adjustment cycle.

[0052] Specifically, for example, if the target opening value is 70% and the current opening value is 50%, the difference is 20%. This 20% difference can be used as the input value for the PID algorithm, and the target opening value of 70% can be used as the setpoint for the PID algorithm. If the opening value of the blinds adjusted using the PID algorithm in this adjustment cycle is 55%, then the difference of 15% between the adjusted opening value of 55% and the target opening value of 70% can be used as the input value for the next adjustment cycle of the PID algorithm. The PID algorithm can then be used to adjust the opening value of the blinds until the opening value reaches the target opening value of 70%.

[0053] The above technical solution acquires external meteorological parameters and the current opening value of the louvers. Based on the acquired meteorological parameters, a target opening value for the louvers is determined. The difference between the target opening value and the current opening value is calculated. Based on this difference, a proportional-integral-derivative (PID) algorithm is used to adjust the louver opening value to achieve the target opening value. This allows for adaptive, precise, and reliable adjustment of the louver opening, saving manpower and improving the factory's heat dissipation efficiency.

[0054] In yet another embodiment, the meteorological parameters mentioned above include ambient temperature and / or rainfall.

[0055] The opening degree of the louvers determines the size of the "aperture" through which air circulates inside and outside the factory, thus determining the heat dissipation effect.

[0056] When the acquired meteorological parameter is ambient temperature, the target opening value of the venetian blinds corresponding to the acquired ambient temperature can be found from a predetermined correspondence and used as the determined target opening value. Based on the difference between the determined target opening value and the acquired current opening value, a PID algorithm is used to adjust the opening value of the venetian blinds so that the opening value of the venetian blinds reaches the target opening value.

[0057] This design can balance heat dissipation needs with the impact of dust and insects after the window is opened, by pre-determining the correlation between ambient temperature and the target opening degree of the blinds. There doesn't necessarily need to be a positive correlation between ambient temperature and blind opening degree; matching can be done based on experience.

[0058] When the acquired meteorological parameter is rainfall, the target opening value of the venetian blinds corresponding to the acquired rainfall can be found from a predetermined correspondence and used as the determined target opening value. Based on the difference between the determined target opening value and the acquired current opening value, a PID algorithm is used to adjust the opening value of the venetian blinds to achieve the target opening value. When the rainfall outside the factory is high, the corresponding target opening value of the venetian blinds can be set to a smaller value; when the rainfall outside the factory is low, the corresponding target opening value of the venetian blinds can be set to a larger value.

[0059] When the acquired meteorological parameters are ambient temperature and rainfall, the final target opening value of the blinds can be determined by combining two target opening values ​​based on a predetermined strategy. For example, if the target opening value of the blinds determined based on ambient temperature is 80%, and the target opening value determined based on rainfall is 10% (e.g., heavy rainfall outside the factory), there is a significant difference between the target opening value determined by rainfall and the target opening value determined by ambient temperature. In this case, priority can be given to ensuring that the equipment inside the factory is not at risk of being damaged by moisture, and the target opening value of the blinds can be set at 10%. As another example, if the target opening value of the blinds determined based on ambient temperature is 50%, and the target opening value determined based on rainfall is 40%, the difference between the target opening value determined by rainfall and the target opening value determined by ambient temperature is not significant, and the target opening value of the blinds can be set to the average value of 45%.

[0060] In this embodiment, the influence of ambient temperature and rainfall was considered when determining the target opening value of the louvers, so that the determined louver opening not only met the heat dissipation requirements, but also avoided unnecessary damage from external dust and rain.

[0061] In another embodiment, the factory building is further equipped with a fan unit, which is used to blow air into or out of the factory building through louvers. The above method also includes:

[0062] Obtain the temperature inside the factory and the wind direction outside the factory;

[0063] Adjust the start-up and shutdown status of the fan units according to the temperature inside the factory and the determined target opening value;

[0064] Adjust the rotation direction of the wind turbine unit according to the obtained wind direction.

[0065] Fan units can be installed inside the factory to blow air into or out of the factory through louvers. These fan units can be located on the side closest to the factory interior, adjusting the airflow speed by blowing air in and out, thereby regulating the factory's heat dissipation capacity. When the internal temperature is high, the airflow speed can be increased to improve heat dissipation. However, since the air blown by the fan units must pass through the louvers, when the louvers are closed, the airflow cannot circulate between the inside and outside of the factory. Therefore, even when the fan units are running, the heat dissipation effect is limited. Thus, after obtaining the internal temperature of the factory, the start / stop status of the fan units can be adjusted based on the temperature and the determined target louver opening value.

[0066] The rotation direction of the fan unit determines the direction of the airflow it blows out. When the wind outside the factory flows into the factory through the louvers, if the fan unit blows the air out through the louvers, it conflicts with the natural wind direction, and the wind outside the factory cannot effectively flow into the factory, resulting in low heat dissipation efficiency. When the wind outside the factory flows into the factory through the louvers, if the fan unit blows the air out through the louvers, it will have the same wind direction as the wind outside the factory. The wind outside the factory can flow into the factory at a greater flow rate, increasing the air circulation speed inside the factory and improving heat dissipation efficiency. Therefore, after obtaining the wind direction outside the factory, the rotation direction of the fan unit can be adjusted accordingly.

[0067] In this embodiment, the start-stop status of the fan unit can be accurately and reliably adjusted according to the temperature inside the factory and the determined target opening value, avoiding energy waste. At the same time, the rotation direction of the fan unit can be adjusted in a timely and effective manner according to the obtained wind direction, ensuring the heat dissipation efficiency of the factory.

[0068] In another embodiment, adjusting the start / stop status of the fan unit based on the internal temperature of the plant and the determined target opening value includes:

[0069] If the temperature inside the factory building is greater than the predetermined first temperature threshold, and the determined target opening value is greater than the predetermined first opening threshold, then the fan unit will be adjusted to be in operation.

[0070] If the temperature inside the plant is less than the predetermined second temperature threshold, and the determined target opening value is less than the predetermined second opening threshold, then the fan unit is adjusted to be in a stopped state, the first temperature threshold is greater than the second temperature threshold, and the first opening threshold is greater than the second opening threshold.

[0071] The first temperature threshold can be preset by the designer, for example, it can be 45℃. The first opening threshold can also be preset by the designer, for example, it can be 70%. When the temperature inside the factory exceeds the preset first temperature threshold and the determined target opening value exceeds the preset first opening threshold, the louver opening value is larger, and the air blown out by the fan unit can flow through the louvers to the inside or outside of the factory. Furthermore, the temperature inside the factory is high, so the fan needs to be turned on to accelerate the air circulation speed inside the factory and improve the heat dissipation capacity inside the factory. Therefore, the fan unit can be adjusted to be in operation.

[0072] When the temperature inside the factory exceeds the predetermined first temperature threshold and the determined target opening value is less than the predetermined first opening threshold, the opening value of the louvers is small. Under these circumstances, even if the fan unit is turned on, the heat dissipation efficiency inside the factory is very limited, so the fan unit is not adjusted to be in operation.

[0073] The second temperature threshold can be preset by the designer, for example, it can be 40℃. The second opening threshold can also be preset by the designer, for example, it can be 5%. When the temperature inside the factory is lower than the preset second temperature threshold and the determined opening value is lower than the preset second opening threshold, it can be considered that the louvers are basically closed and the temperature inside the factory is low, the heat dissipation demand inside the factory is low, and the fan unit can be adjusted to be stopped.

[0074] In this embodiment, the start-up and shutdown status of the wind turbine can be easily adjusted based on the threshold comparison results, and the reliability is high.

[0075] In another embodiment, the fan unit includes a first fan and a second fan, which are respectively disposed on opposite sides of the factory building. The aforementioned adjustment of the fan rotation direction based on the acquired wind direction includes:

[0076] If the wind direction is obtained as flowing into the factory building from the first fan, then the rotation direction of the first fan is controlled to blow air into the factory building, and the rotation direction of the second fan is controlled to blow air out of the factory building.

[0077] The fan unit may include a first fan and a second fan respectively located on opposite sides of the factory building. For example, the first fan and the second fan may be located on the north and south sides of the factory building, or on the east and west sides of the factory building, respectively. Both the first fan and the second fan are equipped with corresponding louvers.

[0078] When the wind direction is from the first fan flowing into the factory building, the rotation direction of the first fan can be controlled to blow air into the factory building, which is the same as the wind direction outside the factory building, thus accelerating the efficiency of air flowing into the factory building. At the same time, the rotation direction of the second fan, which is located on the opposite side of the first fan, can be controlled to blow air out of the factory building. In this way, the air blown into the factory building through the louvers and the first fan can be quickly blown out of the factory building through the second fan, improving the air circulation speed inside the factory building and enhancing the convective heat transfer effect.

[0079] Similarly, when the wind direction is obtained as flowing into the factory from the second fan, the rotation direction of the second fan can be controlled to blow air into the factory, and the rotation direction of the first fan can be controlled to blow air out of the factory.

[0080] In this embodiment, by adjusting the rotation direction of the fans located on opposite sides of the factory building, the air circulation speed inside the factory building can be accelerated, thereby improving heat dissipation efficiency.

[0081] In yet another embodiment, the method further includes:

[0082] If the ambient temperature inside the factory exceeds a predetermined third temperature threshold when the first fan blows air into the factory building, a steam leak accident is determined to have occurred in the factory building.

[0083] If a steam leak is confirmed to have occurred in the plant, the first fan is controlled to blow air out of the plant, and the third temperature threshold is greater than the first temperature threshold.

[0084] The third temperature threshold can be preset by the designer, for example, it can be 80℃. When the first fan is blowing air into the plant, if the ambient temperature inside the plant exceeds the preset third temperature threshold, the temperature inside the plant is too high and exceeds the normal temperature range during normal production, indicating a steam leak. After confirming a steam leak, the first fan can be switched to blowing air out of the plant, allowing the leaked steam to flow out of the plant quickly.

[0085] In this embodiment, it is possible to easily determine whether a steam leak has occurred based on the threshold comparison result, and after determining that a steam leak has occurred, the fan is controlled to blow air to the outside of the plant, which can dissipate heat from the plant in a timely and effective manner, thereby improving safety.

[0086] In yet another embodiment, the method further includes:

[0087] If a steam leak is confirmed to have occurred in the plant, an alarm message will be output.

[0088] When a steam leak is detected in the plant, an alarm message can be output. For example, a pop-up message can be displayed on the control room's display screen: "A steam leak has occurred. Please handle it promptly."

[0089] In this embodiment, by outputting alarm messages, staff can take timely corresponding measures, thereby improving safety.
