However, research is lacking on the pipe layout of medium-deep buried pipe heat exchanger groups and the control of the outlet water temperature of the heat exchanger tubes. Therefore, current medium-deep buried pipe heat exchanger groups suffer from poor water temperature control performance and low accuracy. Summary of the Invention

[0071] Figure 3 This is a schematic diagram of the structure of an electronic device for implementing the heat exchanger remote control method based on covert communication, according to an embodiment of the present invention.

[0072] The objectives, features, and advantages of this invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0073] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0074] This application provides a method for remote control of a heat exchanger based on covert communication. The executing entity of this method includes, but is not limited to, at least one of the following electronic devices that can be configured to execute the method provided in this application: a server, a terminal, etc. In other words, the method for remote control of a heat exchanger based on covert communication can be executed by software or hardware installed on a terminal device or a server device. The server includes, but is not limited to, a single server, a server cluster, a cloud server, or a cloud server cluster.

[0075] Example 1:

[0076] Reference Figure 1 The diagram shown is a flowchart illustrating a remote control method for heat exchangers based on covert communication according to an embodiment of the present invention. In this embodiment, the remote control method for heat exchangers based on covert communication includes:

[0077] S1. Calculate the geothermal characteristic value of the target geothermal area using the pre-constructed geothermal characteristic calculation formula, and calculate the pipe group spacing value using the pre-constructed geothermal pipe group spacing formula based on the geothermal characteristic value.

[0078] Explained, the target geothermal area is the area where a medium-deep buried pipe heat exchanger system is planned to be constructed, and the medium-deep buried pipe heat exchanger system is a coaxial tube-insertion type heat exchanger.

[0079] In detail, the formula for calculating the geothermal characteristics is as follows:

[0080]

[0081] Among them, T z Represents geothermal characteristic value, t d ε represents the surface temperature, q represents the geothermal heat flow, ε represents the convective heat transfer coefficient between air and the surface, i represents the stratigraphic sequence number in the hierarchical geothermal region, n represents the total number of stratigraphic layers, and k represents the surface temperature. i H represents the thermal conductivity of the soil and rock in the i-th stratum. i H represents the coordinate depth of the i-th stratum. i-1 k represents the coordinate depth of the (i-1)th stratum. n H represents the thermal conductivity of the soil and rock in the nth stratum, z represents the pipe burial depth, and H represents the thermal conductivity of the soil and rock in the nth stratum. n This represents the coordinate depth of the nth stratum.

[0082] Understandably, for ease of calculation, the following assumptions are made: the influence of underground seepage is ignored, and heat transfer in the soil and rock is regarded as a simple heat conduction problem; the influence of surface temperature fluctuations is ignored; the internal circulation of the coaxial tube heat exchanger mainly uses convection heat transfer, and axial heat conduction is ignored.

[0083] In detail, the formula for the spacing of the geothermal pipe group is as follows:

[0084] l=δ×T z

[0085] Where l represents the pipe group spacing value, δ represents the calorific value conversion coefficient, and T z This represents the geothermal characteristic value.

[0086] Understandably, when the geothermal resources of the target geothermal area are relatively abundant, it means that the geothermal value of the area is relatively large, so the spacing between adjacent buried pipes can be appropriately increased; when the geothermal value of the target geothermal area is relatively small, the spacing between adjacent buried pipes can be appropriately decreased.

[0087] In this embodiment of the invention, calculating the geothermal characteristic values ​​of the target geothermal area using a pre-constructed geothermal characteristic calculation formula includes:

[0088] The target geothermal area is divided into stratigraphic layers to obtain hierarchical geothermal areas;

[0089] The geothermal characteristic value at a preset buried pipe depth in the hierarchical geothermal region is calculated using the aforementioned geothermal characteristic calculation formula.

[0090] Explained, the hierarchical geothermal region refers to an area containing multiple geothermal levels (strata) obtained by dividing the target geothermal region into strata based on factors such as heat fluid transport methods, temperature ranges, and rock types. The preset buried pipe depth refers to the maximum buried depth of the buried pipe in the medium-deep buried pipe heat exchanger system. The geothermal characteristic value refers to the geothermal value at the preset buried pipe depth.

[0091] S2. Obtain the unit structure shape of the buried heat exchange pipe group, and determine the system distribution structure of the buried heat exchange pipe group based on the pipe group spacing value and the unit structure shape.

[0092] Optionally, the shape of the unit structure refers to the shape of the area where each buried pipe is located. It can be a rhombus, because the distance between the center points of multiple spliced ​​rhombuses is equal, which allows each buried pipe to obtain geothermal resources equally.

[0093] In this embodiment of the invention, determining the system distribution structure of the buried heat exchanger pipe group based on the pipe group spacing value and the unit structure shape includes:

[0094] The tube group spacing value is used as the side length of the unit structure shape, wherein the unit structure shape is a rhombus;

[0095] Construct a set of underground unit areas based on the side length of the unit structure shape and the preset number of underground pipe groups;

[0096] By splicing together each unit buried area in the unit buried area set, a buried pipe group zoning map is obtained;

[0097] Extract the center point of each unit of the underground pipe group zoning map, and use the center point as the underground location of the underground pipe;

[0098] The system distribution structure of the buried heat exchanger pipe group is obtained by summarizing the underground locations of all buried pipes in the buried heat exchanger pipe group.

[0099] S3. Construct a buried heat exchanger pipe group system according to the system distribution structure, and use pre-constructed covert communication technology to sequentially obtain the current inlet temperature, current outlet temperature and current inlet flow rate of the working fluid for each heat exchanger pipe in the buried heat exchanger pipe group system.

[0100] Explained, the aforementioned covert communication technology refers to a communication technology that enables the hidden transmission of information between communicating parties to prevent the communication signal from being discovered by malicious eavesdroppers; it is also known as low probability of detection (LPD) communication technology.

[0101] Furthermore, the current inlet temperature of the working fluid refers to the temperature at which the working fluid enters the heat exchange tube inlet, the current outlet temperature of the working fluid refers to the temperature at which the working fluid flows out of the heat exchange tube outlet, and the current inlet flow rate of the working fluid refers to the flow rate of the working fluid entering the heat exchange tube inlet per unit time. The working fluid refers to a liquid heated using geothermal resources, which can be water.

[0102] In this embodiment of the invention, the step of sequentially acquiring the current inlet temperature, current outlet temperature, and current inlet flow rate of the working fluid for each heat exchanger tube in the buried heat exchanger tube group system using pre-built covert communication technology includes:

[0103] Randomly select a target communication time slot from the pre-built set of communication time slots;

[0104] The communication symbol period is independently selected in the target communication time slot with random probability p;

[0105] Based on the target communication time slot and communication symbol period, the current inlet temperature, current outlet temperature, and current inlet flow rate of the working fluid for each heat exchanger tube in the buried heat exchanger tube group system are extracted and transmitted to the pre-constructed working fluid flow control platform.

[0106] Explained, the working fluid flow control platform refers to a platform that controls the current inflow rate of the working fluid in the buried heat exchanger pipe group system and monitors various operating parameters of the buried heat exchanger pipe group system. The covert communication technology is existing technology and will not be described in detail here.

[0107] S4. Based on the pre-constructed energy balance formula and the expected outlet temperature of the working fluid, calculate the target inlet flow rate of the working fluid using the current inlet temperature, current outlet temperature, and current inlet flow rate of the working fluid.

[0108] Understandably, the target inlet flow rate of the working fluid refers to the working fluid flow rate that the working fluid ultimately needs to be adjusted to enter the heat exchange tube inlet per unit time.

[0109] In detail, the energy balance formula is as follows:

[0110]

[0111] Where m represents the mass of the working fluid, c represents the specific heat capacity of the working fluid, and T y-out T represents the expected outlet temperature of the working fluid. d-out The current outlet temperature of the working fluid is represented by t, and time is represented by f. m-in f represents the target inlet flow rate of the working fluid. d-in T represents the current inflow rate of the working fluid into the pipe. o T represents the current inlet temperature of the working fluid. y-iout The expected outlet temperature of the working fluid is represented by K, the heat transfer coefficient is represented by A, the heat conduction area is represented by T′, and the average geothermal value at the location of the heat exchange tube is represented by T′.

[0112] Explainable This represents the derivative of the expected outlet temperature of the working fluid with respect to time. Once the expected outlet temperature of the working fluid is obtained, the corresponding target inlet flow rate of the working fluid can be calculated according to the energy balance formula. By adjusting the magnitude of the target inlet flow rate of the working fluid, the current outlet temperature of the working fluid can be adjusted until the expected outlet temperature of the working fluid is reached.

[0113] Furthermore, due to the different surrounding environments of buried pipes at different locations and the influence of the current inlet temperature of the working fluid in different ground pipes, for example, the geothermal value of buried pipes at the edge is less affected by the interference of adjacent buried pipes than that of buried pipes in the middle, which may lead to different outlet temperatures of the working fluid in different buried pipes. In order to ensure that the current outlet temperature of the working fluid in different buried pipes is the same, or to achieve controllability of the current outlet temperature of the working fluid in different buried pipes, the outlet temperature of the working fluid in different buried pipes can be adjusted by using the energy balance formula and the target inlet flow rate of the working fluid.

[0114] In this embodiment of the invention, the step of calculating the target inlet flow rate of the working fluid based on the pre-constructed energy balance formula and the expected outlet temperature of the working fluid, using the current inlet temperature, current outlet temperature, and current inlet flow rate of the working fluid, includes:

[0115] Obtain the axial length of the heat exchange tube and the radial length of the outer tube;

[0116] The heat transfer area of ​​the heat exchange tube is calculated using a pre-constructed heat transfer area calculation formula based on the axial length and the radial length of the outer tube.

[0117] Calculate the median geothermal value of each stratum in the hierarchical geothermal region according to the geothermal characteristic calculation formula;

[0118] Based on the pre-constructed geothermal mean calculation formula, the average geothermal value at the location of the heat exchanger pipe is calculated using the geothermal median value of each stratum.

[0119] Based on the pre-constructed energy balance formula and the expected outlet temperature of the working fluid, the target inlet flow rate of the working fluid is calculated using the current inlet temperature of the working fluid, the current outlet temperature of the working fluid, the current inlet flow rate of the working fluid, the average geothermal value, and the heat conduction area.

[0120] It should be understood that the heat exchange tube is a coaxial tube-insertion heat exchanger, therefore comprising an inner tube and an outer tube. The portion between the inner and outer tubes forms an external annular cavity. The working fluid flows into the external annular cavity and out through the inner tube. The working fluid is primarily heated within the external annular cavity. Therefore, the thermal conductivity area refers to the lateral area of ​​the outer tube. The median geothermal value refers to the average geothermal value of each stratum. For example, if the minimum geothermal value of a certain stratum is 65 degrees Celsius and the maximum geothermal value is 70 degrees Celsius, then the median geothermal value of that stratum is 67.5 degrees Celsius. The average geothermal value refers to the average geothermal value at the location of the heat exchange tube.

[0121] Furthermore, the formula for calculating the thermal conductivity area is as follows:

[0122] A=2πΔd r ×d l

[0123] Where, d r d represents the radial length of the outer tube of the heat exchanger. l This indicates the axial length of the heat exchange tube. The radial length of the outer tube refers to the radius of the outer tube circle.

[0124] In detail, the formula for calculating the average geothermal value is as follows:

[0125]

[0126] Among them, T i-mid This represents the median geothermal value of the i-th stratum.

[0127] S5. Calculate the target pump power based on the target inlet flow rate of the working fluid and the pre-constructed working fluid flow rate power formula.

[0128] Understandably, the inflow rate of different working fluids can be adjusted by the power of the water pump. When the power of the water pump is increased, the inflow rate of the working fluid will also increase.

[0129] In detail, the working fluid flow rate power formula is as follows:

[0130]

[0131] Where p represents the target pump power, ρ represents the working fluid density, g represents the gravitational constant, h represents the working fluid extraction height, and η represents the motor efficiency.

[0132] In this embodiment of the invention, the extracted working fluid can be stored in a water tank at a certain height, so the average height of the water tank is equivalent to the extraction height. The higher the extraction height, the greater the required target water pump power.

[0133] S6. Using the target water pump power, adjust the current inlet flow rate of the working fluid in the heat exchange tube to the target inlet flow rate of the working fluid, thereby completing the remote control of the heat exchanger based on covert communication.

[0134] In this embodiment of the invention, adjusting the current inlet flow rate of the working fluid in the heat exchange tube to the target inlet flow rate using the target water pump power includes:

[0135] Calculate the difference in working fluid inlet flow rate based on the target inlet flow rate and the current inlet flow rate of the working fluid.

[0136] The flow rate adjustment gradient is calculated based on the difference in the working fluid inlet flow rate and the preset adjustment cycle.

[0137] Calculate the power adjustment gradient based on the flow rate adjustment gradient and the working fluid flow rate power formula;

[0138] The current inlet flow rate of the working fluid in the heat exchange tube is adjusted to the target inlet flow rate of the working fluid according to the power adjustment gradient.

[0139] Explained, the difference in inlet flow rate of the working fluid refers to the difference between the target inlet flow rate of the working fluid and the current inlet flow rate of the working fluid. The adjustment period refers to the duration of adjusting the current inlet flow rate of the working fluid. For example, if the adjustment period is 5 minutes and the difference in inlet flow rate of the working fluid is 0.5 cubic meters per second, then the flow rate adjustment gradient is an increase of 0.1 cubic meters per minute. When the current inlet flow rate of the working fluid is 1 cubic meter per second, then the first second is 1.1 cubic meters per second and the second second is 1.2 cubic meters per second.

[0140] Compared to the background technology, current medium-deep buried heat exchanger pipe groups suffer from poor water temperature control performance and low accuracy. This invention calculates the geothermal characteristic values ​​of the target geothermal area using the geothermal characteristic calculation formula, and then calculates the pipe group spacing value using the geothermal pipe group spacing formula based on these characteristics. Once the pipe group spacing value is obtained, the system distribution structure of the buried heat exchanger pipe group can be determined based on the spacing value and the unit structure shape. After constructing the buried heat exchanger pipe group system based on the system distribution structure, to improve information confidentiality and security, covert communication technology can be used to sequentially obtain the working data of each heat exchanger pipe in the buried heat exchanger pipe group system. Given the current inlet temperature, outlet temperature, and flow rate of the working fluid, the target inlet flow rate can be calculated using the energy balance formula and the expected outlet temperature. This allows for the adjustment of the current outlet temperature to the expected outlet temperature. After obtaining the target inlet flow rate, the target pump power can be calculated using the working fluid flow rate power formula. Finally, the current inlet flow rate of the working fluid in the heat exchanger tubes is adjusted to the target inlet flow rate, completing remote control of the heat exchanger based on covert communication. Therefore, the remote control method, device, electronic equipment, and computer-readable storage medium for heat exchangers based on covert communication proposed in this invention can solve the problems of poor water temperature control performance and low accuracy in current medium-deep buried pipe heat exchanger groups.

[0141] Example 2:

[0142] like Figure 2 The diagram shown is a functional block diagram of a heat exchanger remote control device based on covert communication provided in an embodiment of the present invention.

[0143] The heat exchanger remote control device 100 based on covert communication described in this invention can be installed in an electronic device. Depending on the functions implemented, the heat exchanger remote control device 100 based on covert communication may include a system distribution structure determination module 101, a heat exchange tube operating parameter extraction module 102, a working fluid target inlet flow rate calculation module 103, a target water pump power calculation module 104, and a working fluid current inlet flow rate adjustment module 105. The module described in this invention can also be called a unit, which refers to a series of computer program segments that can be executed by the processor of an electronic device and can perform a fixed function, stored in the memory of the electronic device.

[0144] The system distribution structure determination module 101 is used to calculate the geothermal characteristic value of the target geothermal area using a pre-constructed geothermal characteristic calculation formula, and to calculate the pipe group spacing value based on the geothermal characteristic value using a pre-constructed geothermal pipe group spacing formula, wherein the geothermal pipe group spacing formula is as follows:
