Description

Technical Field

[0001] This invention relates to the field of energy-saving operation and maintenance control technology for electromechanical equipment, specifically an integrated management and control system for energy-saving operation and maintenance of electromechanical equipment based on edge computing. Background Technology

[0002] In industrial production, building power, energy stations, and continuously operating equipment scenarios, multiple electromechanical devices typically operate together according to process flow, spatial arrangement, heat dissipation direction, and cooling resource allocation. Each device generates varying degrees of heat output during operation, and heat transfer may occur between devices due to proximity in installation location, interconnected airflow channels, and consistent heat dissipation directions. To ensure stable equipment operation, existing maintenance methods typically deploy temperature acquisition components, cooling execution components, and edge computing units on the equipment side to collect and process equipment temperature, cooling execution status, and operating load, and perform cooling adjustments and operation maintenance based on the collected results. In the existing energy-saving operation and maintenance control of electromechanical equipment, the common approach is to judge the temperature status of a single device based on a threshold and increase the cooling output when the temperature approaches the boundary of the set range. Some operation and maintenance methods will also adjust the cooling execution amount in conjunction with the operating load of the device. The above methods can meet the basic temperature control requirements of a single device and can also reduce the workload of manual inspection to a certain extent. However, in the scenario of collaborative operation of a group of devices, the heat output change of a certain device may be transmitted to adjacent devices along the thermal correlation direction between devices. The temperature change and cooling enhancement of the subsequent devices are not necessarily caused by their own load changes. It is difficult to distinguish the relationship between the local thermal change, the transmission of upstream heat influence, and the interference of adjustment actions by simply judging based on the temperature of a single point or the cooling execution status of a single device. Furthermore, in multi-device thermal interconnection scenarios, the cooling adjustment action itself will also change the local thermal state change process. If global cooling enhancement is directly performed without clarifying the cross-device thermal impact transmission path, it is easy for subsequent diagnostic objects to be mixed with the influence of the adjustment action, making it difficult to determine whether the thermal impact continues to be transmitted along the original node association direction. Energy-saving operation and maintenance management of electromechanical equipment needs to form periodic state nodes under a unified detection cycle at the edge side to further identify thermal impact events of equipment groups, limit the time window that can be used for diagnosis, read the thermal impact retention state after cooling response, and form a segmented intervention control basis for the thermal impact transmission path between devices. Therefore, this invention proposes an integrated energy-saving operation and maintenance management system for electromechanical equipment based on edge computing. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated management and control system for energy-saving operation and maintenance of electromechanical equipment based on edge computing, so as to solve the problems mentioned in the background art.

[0004] This invention can be achieved through the following technical solution: an integrated management and control system for energy-saving operation and maintenance of electromechanical equipment based on edge computing, comprising: The node module is used to enable the edge computing units on each device side to read the thermal operation status and the thermal correlation parameters between devices, form periodic status nodes according to a unified detection cycle, form state transition quantities based on adjacent periodic status nodes, and establish node associations based on the thermal correlation parameters between devices. The event module is used to read state transition data and node associations. When the thermal output of the state node in the previous cycle is enhanced and the state node in the subsequent cycle continues to be heated and the cooling execution is enhanced in the subsequent unified detection cycle, a device group thermal impact event is formed. The window locking module is used to form a diagnostic locking window based on the thermal impact events of the equipment group, retain the adjustment actions that maintain the preset safe thermal state range, and restrict the adjustment actions that change the direction of thermal impact transmission corresponding to the node association. The developing module is used to read the cooling response status of the cycle status node within the diagnostic locking window, form a cooling and developing node containing the cooling response location and developing retention amount, and form a cooling and developing chain based on the node association. The path module is used to determine the current heat-affected zone transfer path between devices based on the extension of the cooling response position along the node and the connection of the developing retention along the node in the cooling and developing chain, and to form the cooling margin occupancy based on the developing retention in the current heat-affected zone transfer path between devices. The joint control module is used to generate path segmentation intervention commands based on the current heat impact transmission path between devices and the cooling margin occupancy, and to update the device group heat impact events based on the periodic status nodes after execution.

[0005] A further technical improvement of the present invention is that the step of forming a periodic state node by the node module includes: Each device's edge computing unit determines the entry and exit sides of the corresponding electromechanical equipment based on the inter-equipment thermal correlation parameters; Within the same unified testing cycle, the entry-side hot operation status, exit-side hot operation status, and machine cooling execution status are read according to the acquisition time sequence. When entering the side-heating operation state and forming a change in the heating direction, and leaving the side-heating operation state and forming a change in the same direction of heating within the preset number of port transmission cycles, the sampling position where the change in the same direction of heating is formed when leaving the side-heating operation state is taken as the starting position to determine the preset response belonging cycle range. Within the preset response attribution period, when the local cooling execution state forms cooling execution enhancement and the departure side thermal operation state maintains the same direction of heating change, the entry side thermal operation state, the departure side thermal operation state and the local cooling execution state are written into the same period status node. When the thermal operation status on the departure side does not change in the same direction of heating within the preset number of port transmission cycles, the status read within the unified detection cycle will not be written into the periodic status node used to form the state transition quantity. When the local cooling execution status does not form a cooling execution enhancement within the preset response attribution period, the status read within the unified detection period will not be written into the periodic status node used to form the state transition amount. When the thermal operation state on the departure side does not maintain the same direction of heating change within the preset response assignment period, the state read within the unified detection period will not be written into the periodic state node used to form the state transition quantity.

[0006] A further technical improvement of the present invention is that the step of the node module forming state transition quantities based on adjacent periodic state nodes includes: Read the preceding and following cycle status nodes formed by the same electromechanical equipment in adjacent unified detection cycles, and read the entry-side hot operation status, exit-side hot operation status, and machine cooling execution status in the preceding and following cycle status nodes respectively. The difference between the thermal operation state of the entry side in the subsequent cycle state node and the thermal operation state of the entry side in the previous cycle state node is processed to form the progressive value of the entry side state. The difference between the thermal operation state of the departure side in the state node of the subsequent cycle and the thermal operation state of the departure side in the state node of the previous cycle is processed to form the progressive value of the departure side state. When the local cooling execution state in the subsequent cycle state node forms a cooling execution enhancement relative to the local cooling execution state in the previous cycle state node, read the departure side thermal operation state before the cooling execution enhancement and the departure side thermal operation state after the cooling execution enhancement in the subsequent cycle state node, and subtract the latter from the former to form the cooling decrease difference. The incremental correction value of the departure side state is formed by incrementally correcting the temperature drop difference. When the local cooling execution state in the subsequent cycle state node does not form a cooling execution enhancement relative to the local cooling execution state in the preceding cycle state node, the departure side state progression value is determined as the departure side correction progression value. Write the state progression value on the entry side, the correction progression value on the departure side, and the state change result of the local cooling execution into the state transition value of the corresponding electromechanical equipment.

[0007] A further technical improvement of the present invention is that the step of forming a diagnostic lock window in the lock window module includes: Read the node associations in the thermal impact event of the device group, and determine the periodic state node located between the previous periodic state node and the next periodic state node in the node association as the inheriting periodic state node. The unified detection period for enhancing thermal output is formed by the previous period status node is used as the window start period, and the successor period status node and the subsequent period status node are read in the order of the unified detection period. When the thermal operation state corresponding to the receiving cycle state node progresses along the heating direction between adjacent unified detection cycles, and the subsequent cycle state node forms heating continuation and cooling execution enhancement, the adjustment action between the start cycle of the reading window and the unified detection cycle in which the subsequent cycle state node forms heating continuation and cooling execution enhancement is read. When the adjustment action keeps the periodic status node within the preset safe thermal state range, continue to read the periodic status node of the unified detection cycle after the adjustment action. When the adjustment action is not used to keep the periodic state node within the preset safe thermal state range and changes the direction of thermal influence transmission associated with the node, the previous unified detection cycle corresponding to the unified detection cycle of the adjustment action is determined as the window termination cycle. If no adjustment action is read that changes the direction of heat transfer corresponding to the node association, the window termination period is taken as the unified detection period for the heating continuation and cooling execution enhancement of the subsequent periodic state node. A diagnostic lock window is formed based on the window start cycle and the window end cycle.

[0008] A further technical improvement of the present invention is that the step of forming the cooling development node in the developing module includes: Within the diagnostic locking window, read the periodic status nodes associated with the same node in the same detection cycle order, and read the departure side correction increment value in the state transition amount corresponding to the periodic status node. When the departure side correction increment value in an adjacent unified detection cycle changes from a value greater than zero to a value less than zero, the unified detection cycle in which the cycle state node corresponding to the value less than zero is located is determined as the cooling response position. Using the cooling response location as the boundary, continue reading the departure side correction increment value corresponding to the cycle status node in the subsequent unified detection cycle associated with that node; When the departure-side correction increment value after the cooling response position becomes greater than zero again, the developing retention amount is determined based on the departure-side correction increment value that is greater than zero. Write the cooling response location, development retention amount, and corresponding node association into the same cooling and development node; If no positive zero value is read from the departure side correction progression value after the cooling response position, a cooling development node will not be formed under the corresponding node association.

[0009] A further technical improvement of the present invention is that the step of forming a cooling and developing chain based on node association in the developing module includes: Read the node associations in the thermal impact events of the same device group, and read the already formed cooling and developing nodes according to the thermal impact transmission direction corresponding to the node associations; The cooling and developing node that is the first in the direction of heat effect transmission along the node association and has formed a cooling and developing node is taken as the starting cooling and developing node, and the next cooling and developing node is read bit by bit along the node association. When the cooling response position of the next cooling and developing node is later than the cooling response position of the previous cooling and developing node, and the interval between the cooling response position of the previous cooling and developing node and the cooling response position of the next cooling and developing node is within the preset node transmission response cycle, the developing retention amount of the previous cooling and developing node and the developing retention amount of the next cooling and developing node are read. When the ratio between the amount of development retention at the next cooling and development node and the amount of development retention at the previous cooling and development node is within the preset development acceptance ratio range, the previous cooling and development node and the next cooling and development node are written into the same cooling and development chain according to the node association. If any of the following conditions are not met: the cooling response position of the subsequent cooling and developing node is later than the cooling response position of the previous cooling and developing node, the interval is within the preset node transmission response cycle range, or the ratio is within the preset developing acceptance ratio range, the subsequent cooling and developing node will not be written into the same cooling and developing chain.

[0010] A further technical improvement of the present invention is that the step of forming the cooling margin occupancy in the path module includes: Read the electromechanical equipment corresponding to the last cooling and developing node in the current heat effect transmission path between devices along the corresponding heat effect transmission direction, and take it as the affected electromechanical equipment. Read the maximum cooling execution value of the affected electromechanical equipment and the current cooling execution value of the unified detection cycle before the start cycle of the diagnostic locking window. Subtract the current cooling execution value from the maximum cooling execution value to form the baseline cooling margin. Read the development retention amount of the corresponding cooling and developing node of the affected electromechanical equipment in the current heat-affected transfer path between devices, and read the cooling execution increase value of the cooling and developing node from the cooling response position to the development retention formation position; The corresponding value for retention cooling is formed based on the ratio between the increase in cooling performance and the corresponding development retention amount; The initial cooling margin occupancy is calculated by multiplying the developing retention amount of the corresponding cooling node of the affected electromechanical equipment by the corresponding cooling retention value. When the initial cooling margin occupancy is not greater than the baseline cooling margin, the initial cooling margin occupancy is determined as the cooling margin occupancy. When the initial cooling margin occupied is greater than the reference cooling margin, the reference cooling margin is determined as the cooling margin occupied.

[0011] A further technical improvement of the present invention is that the path segmentation intervention command includes a heat output reduction command and an affected compensation cooling command; The heat output reduction command corresponds to the electromechanical equipment corresponding to the cooling and developing node along the heat transfer direction associated with the node in the current inter-device heat transfer path. The affected compensation cooling command corresponds to the electromechanical equipment corresponding to the cooling and developing node along the heat transfer direction associated with the node in the current inter-device heat transfer path. When there is a cooling and developing node between the foremost and the last cooling and developing node in the current heat-affected zone transfer path between devices, the path segmentation intervention instruction also includes a path heat-affected zone reduction instruction, which corresponds to the position of the cooling and developing node between the foremost and the last cooling and developing node.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention enables edge computing units on each device side to read thermal operating status and inter-device thermal correlation parameters within a unified detection cycle through node modules, and to form periodic state nodes, state transition amounts, and node associations. This allows the thermal operating status of the entering side, the thermal operating status of the leaving side, and the local cooling execution status to be bound and processed under the same time boundary. As a result, the judgment of thermal impact transmission between devices no longer depends solely on the temperature value of a single device, but can form a group of device thermal impact events with temporal and locational attribution based on the node association direction and the state transition relationship between the preceding and following periodic state nodes. Furthermore, this invention uses a window locking module to form a diagnostic locking window based on the thermal impact events of the equipment group, and distinguishes between adjustment actions that maintain a preset safe thermal state range and adjustment actions that change the direction of thermal impact transmission corresponding to the node association, so that the subsequent cooling response status reading is limited to the periodic range in which the original thermal impact transmission direction is not destroyed; thus, the developing module can read the cooling response status of the periodic status node within the diagnostic locking window, forming a cooling and developing node that includes the cooling response position and the developing retention amount, and forming a cooling and developing chain based on the node association, so that the heat progression amount that still exists after cooling can be continuously recorded and chained. On the other hand, the present invention determines the current heat impact transmission path between devices based on the cooling and developing chain through the path module, and forms the cooling margin occupancy based on the developing retention in the path, so that the cooling margin occupancy corresponds to the developing retention at the end of the heat impact transmission path and the reference cooling margin; the joint control module further generates path segment intervention commands based on the current heat impact transmission path between devices and the cooling margin occupancy, and updates the device group heat impact event based on the periodic status node after execution, so that heat output reduction, path-bearing heat impact reduction and affected compensation cooling can be executed according to different path positions, thereby forming a closed-loop control process from device group heat impact identification, diagnosis and locking, cooling and developing, path determination to segment intervention and event update. Attached Figure Description

[0013] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0014] Figure 1 This is a schematic diagram of the system logic of the present invention. Detailed Implementation

[0015] To further illustrate the technical means and effects of the present invention in achieving the intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0016] Please see Figure 1 As shown, this invention provides an integrated management and control system for energy-saving operation and maintenance of electromechanical equipment based on edge computing, including: The node module is used to enable the edge computing units on each device side to read the thermal operation status and the thermal correlation parameters between devices, form periodic status nodes according to a unified detection cycle, form state transition quantities based on adjacent periodic status nodes, and establish node associations based on the thermal correlation parameters between devices. Specifically, in this embodiment, the node module enables the edge computing units on each device side to read the thermal operating status and inter-device thermal correlation parameters. The thermal operating status includes the device thermal state value, the direction of thermal state change, the sampling position, the sampling sequence, and the state source position. The device thermal state value is the Celsius temperature value read by the temperature acquisition component at the corresponding sampling position; the sampling position is the first sampling point, the second sampling point to the last sampling point arranged in the order of sampling within a unified detection period; the sampling sequence is the arrangement order of each sampling position within a unified detection period; the state source position is used to write one of the position records in the entry-side position record and the exit-side position record. When the device thermal state value at the later sampling position is greater than the device thermal state value at the previous sampling position, the corresponding adjacent sampling position is written with a change in the heating direction; when the device thermal state value at the later sampling position is less than the device thermal state value at the previous sampling position, the corresponding adjacent sampling position is written with a change in the cooling direction.

[0017] The inter-equipment thermal correlation parameters include the direction of heat transfer, associated electromechanical equipment, entry position, exit position, node correlation direction, and cooling effect attribution position. The direction of heat transfer is determined by the installation position of the electromechanical equipment and the recorded heat dissipation flow direction; associated electromechanical equipment refers to the electromechanical equipment corresponding to both ends of the heat transfer direction; the entry position is the side where the heat transfer direction points to the corresponding electromechanical equipment; the exit position is the side where the heat transfer continues from the corresponding electromechanical equipment to the next electromechanical equipment; the node correlation direction is used to determine the arrangement order of the previous and subsequent cycle state nodes; the cooling effect attribution position is used to determine the cooling execution position corresponding to the local cooling execution state. After reading the cooling effect attribution position, the node module writes the cooling execution value generated by the corresponding electromechanical equipment at the cooling effect attribution position into the local cooling execution state, ensuring that the local cooling execution state shares the same electromechanical equipment attribution with the entry-side thermal operation state and the exit-side thermal operation state.

[0018] The unified detection cycle is a time processing unit for synchronous reading performed by the edge computing units on each device side. Each unified detection cycle includes a unified detection cycle number, a cycle start sampling position, a cycle end sampling position, and a sampling sequence within the cycle. The unified detection cycle number increments sequentially according to the order in which detections occur. The sampling cycle is a time measurement unit between two adjacent sampling positions within the same unified detection cycle. The number of sampling cycles is obtained by counting adjacent sampling positions according to the sampling sequence within the unified detection cycle. Taking a unified detection cycle containing six sampling positions as an example, the cycle start sampling position is the first sampling point, the cycle end sampling position is the sixth sampling point, and the sampling sequence within the cycle is the arrangement order of the first to sixth sampling points.

[0019] The machine's cooling execution status includes the cooling execution value, the direction of cooling execution change, the cooling execution sampling location, and the execution assignment cycle. The cooling execution value is the equivalent cooling output value read from the corresponding electromechanical equipment at the designated cooling action location. The equivalent cooling output value is expressed as a percentage, ranging from 0% to 100%. When the cooling execution value at a later sampling location is greater than that at a previous sampling location, the corresponding adjacent sampling location is written as "cooling execution enhancement"; when the cooling execution value at a later sampling location is less than that at a previous sampling location, the corresponding adjacent sampling location is written as "cooling execution weakening". The cooling execution sampling location is the sampling location where the cooling execution value changes, and the execution assignment cycle is the unified detection cycle to which that cooling execution sampling location belongs.

[0020] When a node module forms a periodic state node, the edge computing units on each device side determine the entry and exit sides of the corresponding electromechanical equipment based on the inter-device thermal correlation parameters. Specifically, the node module reads the heat transfer direction and the associated electromechanical equipment, designating the side where the heat transfer direction points to the corresponding electromechanical equipment as the entry side, and the side where the heat transfer continues outward from the corresponding electromechanical equipment as the exit side. When multiple heat transfer directions exist for the same electromechanical equipment, the node module forms corresponding entry and exit sides according to different heat transfer directions, and executes the periodic state node formation process for each.

[0021] After determining the entry and exit sides, the node module reads the entry-side thermal operation status, exit-side thermal operation status, and local cooling execution status according to the acquisition sequence within the same unified detection cycle, and writes them into the same temporary processing area according to the unified detection cycle number. The node module reads the device thermal status values ​​of adjacent sampling positions in the entry-side thermal operation status. When the device thermal status value of the later sampling position is greater than the device thermal status value of the previous sampling position, it is determined that the entry-side thermal operation status has formed a change in heating direction, and the sampling position corresponding to the change in heating direction is recorded.

[0022] After the node module enters the side-heating operation state and forms a change in the heating direction, it reads the departure side-heating operation state and determines whether the departure side-heating operation state forms a change in the same heating direction within a preset number of port transmission cycles. The preset number of port transmission cycles is determined as follows: During the commissioning phase, the node module reads historical detection data of the same electromechanical equipment, recording the sampling positions where the change in heating direction occurs upon entering the side-heating operation state and the sampling positions where the change in the same heating direction occurs upon leaving the side-heating operation state; according to the sampling sequence within a unified detection cycle, the number of sampling cycles between the two sampling positions is calculated; the maximum value of the number of sampling cycles obtained from at least five historical detection data is taken, and this maximum value is determined as the preset number of port transmission cycles. In this embodiment, the number of sampling cycles corresponding to the five historical detection data are 1, 2, 2, 1, 2 respectively, so the preset number of port transmission cycles is determined to be two sampling cycles. Within two sampling cycles after the node module enters the side thermal operation state and forms a change in the heating direction, it reads the departure side thermal operation state. When the thermal state value of the device at the next sampling position in the departure side thermal operation state is greater than the thermal state value of the device at the previous sampling position, it is determined that the departure side thermal operation state has formed a change in the same heating direction within a preset number of port transmission cycles.

[0023] When a change in heating direction occurs during the entry into the side-heating operation state, and a change in the same heating direction occurs within the preset number of port transmission cycles after leaving the side-heating operation state, the node module uses the sampling position where the change in the same heating direction occurs during the leaving side-heating operation state as the starting position to determine the preset response assignment cycle range. The preset response assignment cycle range is determined as follows: the node module reads the sampling positions where the change in the same heating direction occurs during the leaving side-heating operation state and the sampling positions where the cooling execution is enhanced during the local cooling execution state from historical detection data; it calculates the number of sampling cycles between the two sampling positions according to the sampling sequence within a unified detection cycle; it takes the maximum value of the number of sampling cycles obtained from at least five historical detection data, and determines the sampling cycle range corresponding to the maximum value as the preset response assignment cycle range. In this embodiment, the number of sampling cycles corresponding to the five historical detection data are 2, 3, 2, 3, and 1 respectively, so the preset response assignment cycle range is three sampling cycles from the starting position.

[0024] Within the preset response attribution period, the node module reads the local cooling execution status and the departure-side thermal operation status. When the cooling execution value at the next sampling position in the local cooling execution status is greater than the cooling execution value at the previous sampling position, it is determined that the local cooling execution status has formed enhanced cooling execution. When the difference in the device thermal state values ​​at all adjacent sampling positions within the preset response attribution period of the departure-side thermal operation status is greater than zero, it is determined that the departure-side thermal operation status maintains the same direction of heating change. When the local cooling execution status forms enhanced cooling execution and the departure-side thermal operation status maintains the same direction of heating change, the node module binds the departure-side thermal operation status, the departure-side thermal operation status, and the local cooling execution status with the corresponding electromechanical equipment and a unified detection cycle number, and writes them into the same cycle status node.

[0025] When the thermal operation status on the departure side does not exhibit a change in the same direction of heating within the preset port transmission cycle, the node module will not write the status read within that unified detection cycle into the periodic status node used to form the state transition quantity. When the local cooling execution status does not exhibit enhanced cooling execution within the preset response attribution cycle, the node module will not write the status read within that unified detection cycle into the periodic status node used to form the state transition quantity. When the thermal operation status on the departure side has at least one adjacent sampling location with a thermal state value difference not greater than zero within the preset response attribution cycle, the node module will not write the status read within that unified detection cycle into the periodic status node used to form the state transition quantity.

[0026] When the node module forms state transition quantities based on adjacent cycle state nodes, it reads the preceding and following cycle state nodes formed by the same electromechanical equipment within adjacent unified detection cycles. The preceding cycle state node is the cycle state node with the earlier unified detection cycle number, and the following cycle state node is the cycle state node with the later unified detection cycle number. The node module reads the entry-side hot operation state, departure-side hot operation state, and local cooling execution state from the preceding and following cycle state nodes, respectively.

[0027] The node module performs difference processing between the entry-side thermal operation status in the subsequent cycle state node and the entry-side thermal operation status in the preceding cycle state node to form an entry-side state progression value. The difference processing is performed by subtracting the thermal state value of the device at the cycle termination sampling position of the entry-side thermal operation status in the preceding cycle state node from the thermal state value of the device at the cycle termination sampling position of the entry-side thermal operation status in the subsequent cycle state node. Similarly, the node module performs difference processing between the departure-side thermal operation status in the subsequent cycle state node and the departure-side thermal operation status in the preceding cycle state node to form a departure-side state progression value. The departure-side state progression value is also performed by subtracting the thermal state value of the device at the cycle termination sampling position of the departure-side thermal operation status in the preceding cycle state node from the thermal state value of the device at the cycle termination sampling position of the departure-side thermal operation status in the subsequent cycle state node.

[0028] After generating the departure-side state progression value, the node module reads whether the local cooling execution state in the subsequent cycle state node results in cooling execution enhancement relative to the local cooling execution state in the preceding cycle state node. When the cooling execution value in the subsequent cycle state node is greater than the cooling execution value in the preceding cycle state node, the node module determines that the local cooling execution state has formed cooling execution enhancement and reads the cooling execution sampling position corresponding to the cooling execution enhancement in the subsequent cycle state node. The node module reads the departure-side thermal operation state corresponding to the sampling position before the cooling execution sampling position, and the departure-side thermal operation state corresponding to the sampling position after the cooling execution sampling position. The cooling drop difference is calculated by subtracting the device thermal state value corresponding to the sampling position after the cooling execution sampling position from the device thermal state value corresponding to the sampling position before the sampling position.

[0029] The node module incrementally corrects the departure-side state progression value based on the cooling drop difference, forming a departure-side corrected progression value. Specifically, the node module adds the departure-side state progression value to the cooling drop difference to obtain the departure-side corrected progression value. When the local cooling execution state in a subsequent cycle state node does not result in a cooling execution enhancement compared to the local cooling execution state in a previous cycle state node, the node module determines the departure-side state progression value as the departure-side corrected progression value. When the departure-side corrected progression value is greater than zero, the node module writes it as a heating direction progression; when the departure-side corrected progression value is less than zero, the node module writes it as a cooling direction progression; when the departure-side corrected progression value is zero, the node module writes it as no progression change.

[0030] After generating the entry-side state progression value, the departure-side corrected progression value, and the local cooling execution state change result, the node module writes these values ​​into the state transition quantity of the corresponding electromechanical equipment. The local cooling execution state change result is formed by subtracting the cooling execution value in the previous cycle's state node from the cooling execution value in the subsequent cycle's state node. The state transition quantity is bound to the corresponding electromechanical equipment, the previous cycle's state node, the subsequent cycle's state node, and the unified detection cycle number.

[0031] When establishing node associations based on inter-device thermal correlation parameters, the node module reads the periodic state nodes and inter-device thermal correlation parameters corresponding to different electromechanical devices. For two periodic state nodes, if the departure position of the electromechanical device corresponding to the preceding periodic state node and the entry position of the electromechanical device corresponding to the following periodic state node have the same thermal influence transmission direction in the inter-device thermal correlation parameters, and the unified detection cycle number of the following periodic state node is not earlier than the unified detection cycle number of the preceding periodic state node, the node module writes the two periodic state nodes into the same node association. In the node association, the periodic state node that is earlier along the thermal influence transmission direction is the preceding periodic state node, and the periodic state node that is later along the thermal influence transmission direction is the following periodic state node. When there is a periodic state node in the node association located between the preceding and following periodic state nodes, and the entry and departure positions of the corresponding electromechanical devices are both consistent with the node association direction, the node module uses this periodic state node as the successor periodic state node. The periodic state nodes, state transition quantities, and node associations thus form a data succession relationship that can be read by the event module.

[0032] The event module is used to read state transition data and node associations. When the thermal output of the state node in the previous cycle is enhanced and the state node in the subsequent cycle continues to be heated and the cooling execution is enhanced in the subsequent unified detection cycle, a device group thermal impact event is formed. Specifically, in this embodiment, the event module is used to read state transition quantities and node associations. When the thermal output of the preceding cycle state node in the node association is enhanced, and the subsequent cycle state node continues to be heated and cooling is enhanced in the subsequent unified detection cycle, a device group thermal impact event is formed. The event module reads the node associations already formed by the node module, and reads the preceding and subsequent cycle state nodes according to the thermal impact transmission direction corresponding to the node association; wherein, the cycle state node earlier along the thermal impact transmission direction is the preceding cycle state node, and the cycle state node later along the thermal impact transmission direction is the subsequent cycle state node.

[0033] The event module reads the state transition value corresponding to the previous cycle state node and retrieves the departure-side correction increment value and the local cooling execution state change result from this state transition value. If the departure-side correction increment value corresponding to the previous cycle state node is greater than zero, and the departure-side position corresponding to this correction increment value is consistent with the direction of heat transfer associated with the node, the event module determines that the heat output of the associated previous cycle state node is enhanced. If the departure-side correction increment value corresponding to the previous cycle state node is not greater than zero, the event module does not use this previous cycle state node as the source of heat output for the device group heat impact event.

[0034] After determining that the thermal output enhancement of the preceding cycle state node is associated with a node, the event module uses the unified detection period of the preceding cycle state node as the starting point for event reading and reads the state transition amount corresponding to the following cycle state node in an increasing direction of the unified detection period number. Subsequent unified detection periods are those with unified detection period numbers later than the unified detection period number corresponding to the event reading starting point. In this embodiment, the event module reads the following cycle state nodes within three unified detection periods after the event reading starting point; these three unified detection periods are implementation examples of subsequent unified detection periods, used to limit the event attribution reading range between the thermal output enhancement of the preceding cycle state node and the thermal continuation of the following cycle state node. In another embodiment, the event attribution reading range is determined based on the number of historical thermal impact response periods between the preceding and following cycle state nodes. The number of historical thermal impact response cycles is determined as follows: The event module reads the historical equipment group thermal impact events associated with the same node, records the unified detection cycle number of the previous cycle state node that forms enhanced thermal output, and the unified detection cycle number of the subsequent cycle state node that forms continued heating and enhanced cooling execution, and calculates the difference between the two unified detection cycle numbers; the maximum value of the number difference obtained from no less than five historical equipment group thermal impact events is taken, and this maximum value is determined as the number of historical thermal impact response cycles.

[0035] The event module reads the departure-side correction increment value from the state transition value corresponding to the subsequent cycle state node. Continued heating of the subsequent cycle state node within the subsequent unified detection cycle means that, within the event's assigned reading range, the departure-side correction increment value corresponding to the subsequent cycle state node is greater than zero, and the unified detection cycle containing this positive departure-side correction increment value is later than the unified detection cycle in which the preceding cycle state node exhibits enhanced thermal output. After the event module reads that the departure-side correction increment value corresponding to the subsequent cycle state node is greater than zero, it continues to read the machine cooling execution state change result corresponding to the same subsequent cycle state node.

[0036] The event module determines cooling performance enhancement based on the change in the local cooling performance status in the state transition value corresponding to the subsequent cycle state node. Cooling performance enhancement means the change in the local cooling performance status is greater than zero; the change in the local cooling performance status is formed by subtracting the cooling performance value in the preceding cycle state node from the cooling performance value in the subsequent cycle state node. When the departure-side correction increment value corresponding to the same subsequent cycle state node is greater than zero, and the change in the local cooling performance status corresponding to that subsequent cycle state node is also greater than zero, the event module determines that the subsequent cycle state node continues to be heated and cooling performance is enhanced in the subsequent unified detection cycle.

[0037] When a node associated with a preceding cycle state node experiences enhanced thermal output, and a subsequent cycle state node experiences continued heating and enhanced cooling execution simultaneously within a later unified detection cycle, the event module writes the preceding cycle state node, the subsequent cycle state node, the corresponding node association, the unified detection cycle in which the preceding cycle state node experiences enhanced thermal output, and the unified detection cycle in which the subsequent cycle state node experiences continued heating and enhanced cooling execution into the same device group thermal impact event. The device group thermal impact event records the cross-device thermal impact process caused by enhanced thermal output from a preceding cycle state node under the same node association, resulting in continued heating and enhanced cooling execution in the subsequent cycle state node.

[0038] When the current periodic state node does not generate a thermal output enhancement, the event module does not generate a device group thermal impact event associated with that node. Similarly, when the subsequent periodic state node does not generate a thermal continuation within a subsequent unified detection cycle, the event module does not generate a device group thermal impact event associated with that node. Furthermore, when the subsequent periodic state node generates a thermal continuation but does not generate a cooling execution enhancement, the event module does not generate a device group thermal impact event associated with that node. Through this process, device group thermal impact events are generated only when there is a clear temporal sequence among the previous thermal output, subsequent thermal continuation, and subsequent cooling execution enhancement within the same node association.

[0039] The window locking module is used to form a diagnostic locking window based on the thermal impact events of the equipment group, retain the adjustment actions that maintain the preset safe thermal state range, and restrict the adjustment actions that change the direction of thermal impact transmission of the node association. Specifically, in this embodiment, the window locking module forms a diagnostic locking window based on the thermal impact events of the device group. After being written by the event module, the thermal impact events of the device group include at least the preceding cycle state node, the following cycle state node, node associations, a unified detection cycle where the preceding cycle state node forms enhanced thermal output, and a unified detection cycle where the following cycle state node forms a cycle where heating continues and cooling execution is enhanced. The window locking module reads the node associations in the thermal impact events of the device group and reads the preceding and following cycle state nodes according to the corresponding thermal impact transmission direction; wherein, the cycle state node preceding the thermal impact transmission direction is the preceding cycle state node, and the cycle state node following the thermal impact transmission direction is the following cycle state node.

[0040] The window locking module reads the node associations in the thermal impact events of the equipment group and identifies the periodic state nodes located between the preceding and following periodic state nodes as the successor periodic state nodes. Specifically, the window locking module reads the node association direction, the departure position of the electromechanical equipment corresponding to the preceding periodic state node, the entry position of the electromechanical equipment corresponding to the following periodic state node, and the periodic state nodes located between the preceding and following periodic state nodes in the node association. When the entry position of the electromechanical equipment corresponding to the periodic state node located between the preceding and following periodic state nodes has the same thermal impact transmission direction as the departure position of the electromechanical equipment corresponding to the preceding periodic state node, and the departure position of the electromechanical equipment corresponding to the following periodic state node also has the same thermal impact transmission direction, this periodic state node is identified as the successor periodic state node. Thus, the successor periodic state node is jointly determined by the entry position, departure position, and thermal impact transmission direction in the node association.

[0041] The window locking module uses the unified detection cycle for enhanced thermal output formed by the previous cycle state node as the window start cycle. Specifically, the window locking module reads the unified detection cycle number for enhanced thermal output formed by the previous cycle state node recorded in the thermal impact event of the equipment group and writes this unified detection cycle number into the window start cycle. Subsequently, the window locking module reads the successor cycle state node and the subsequent cycle state node in ascending order of the unified detection cycle number. The thermal operation state corresponding to the successor cycle state node progresses along the heating direction between adjacent unified detection cycles, meaning that the departure side correction progression value in the state transition amount corresponding to the successor cycle state node is greater than zero. The subsequent cycle state node forms heating continuation and cooling execution enhancement, meaning that the departure side correction progression value in the state transition amount corresponding to the subsequent cycle state node is greater than zero, and the change result of the local cooling execution state is greater than zero.

[0042] As the thermal operating state corresponding to the receiving cycle state node progresses along the heating direction, and the subsequent cycle state node forms a heating continuation and cooling execution enhancement, the window locking module reads the adjustment actions between the window's initial cycle and the unified detection cycle in which the subsequent cycle state node forms a heating continuation and cooling execution enhancement. The adjustment actions include cooling execution value adjustment, equipment operating load adjustment, and heat dissipation flow direction adjustment. Each adjustment action is recorded with an adjustment action number, the corresponding unified detection cycle, the adjustment action's location, and the equipment thermal state values ​​before and after the adjustment action. The adjustment action's location is used to determine whether the adjustment action corresponds to the preceding cycle state node, the receiving cycle state node, or the subsequent cycle state node.

[0043] In this embodiment, the preset safe thermal state range is the range of equipment thermal state values ​​that the corresponding electromechanical equipment at the periodic state node is allowed to maintain. The preset safe thermal state range includes a lower limit and an upper limit. The lower limit is determined based on the lowest permissible thermal state value after the corresponding electromechanical equipment enters a stable operating state, while the upper limit is determined based on the highest permissible thermal state value under rated operating conditions. In this embodiment, the lower limit is 35°C, and the upper limit is 65°C. When, within a unified detection cycle after the adjustment action is executed, the equipment thermal state value at the corresponding periodic state node is not less than the lower limit and not greater than the upper limit, the window locking module determines that the adjustment action keeps the periodic state node within the preset safe thermal state range. The window locking module does not determine the window termination period for this adjustment action and continues to read the periodic state node in the unified detection cycle after the adjustment action, ensuring that the adjustment action maintaining the safe thermal state remains within the diagnostic locking window.

[0044] The window locking module continues to read the adjustment actions between the window's initial cycle and the subsequent cycle's state nodes, forming a unified detection cycle for enhanced heating and cooling execution, and determines whether the adjustment actions change the direction of heat transfer associated with the node. The window locking module reads the direction of heat transfer from the previous cycle's state node to the receiving cycle's state node, and the direction of heat transfer from the receiving cycle's state node to the subsequent cycle's state node within the unified detection cycle after the adjustment action is executed. If the direction of heat transfer from the previous cycle's state node to the receiving cycle's state node is inconsistent with the node association direction in the equipment group's heat impact event, it is determined that the adjustment action has changed the direction of heat transfer associated with the node. Similarly, if the direction of heat transfer from the receiving cycle's state node to the subsequent cycle's state node is inconsistent with the node association direction in the equipment group's heat impact event, it is determined that the adjustment action has changed the direction of heat transfer associated with the node.

[0045] When an adjustment action is not used to keep the periodic status node within the preset safe thermal state range and changes the direction of thermal impact transmission associated with the node, the window locking module determines the previous unified detection cycle corresponding to the adjustment action as the window termination cycle. Specifically, the window locking module reads the unified detection cycle number corresponding to the adjustment action, subtracts one from the unified detection cycle number, and writes the resulting unified detection cycle number into the window termination cycle. If the unified detection cycle corresponding to the adjustment action is the window start cycle, the window locking module determines the window start cycle as the window termination cycle. Through this process, the diagnostic locking window ends before the direction of thermal impact transmission associated with the node is changed, and the periodic status nodes read by the subsequent development module still belong to the original thermal impact transmission direction corresponding to the thermal impact event of the equipment group.

[0046] If no adjustment action changing the direction of heat impact transmission corresponding to the node association is read between the window start cycle and the unified detection cycle in which the subsequent cycle state node forms heat continuation and cooling execution enhancement, the window locking module uses the unified detection cycle in which the subsequent cycle state node forms heat continuation and cooling execution enhancement as the window termination cycle. Specifically, the window locking module reads the unified detection cycle number in the device group thermal impact event recorded for the subsequent cycle state node forming heat continuation and cooling execution enhancement, and writes this unified detection cycle number into the window termination cycle.

[0047] The window locking module forms a diagnostic locking window based on the window start period and window end period. Specifically, the window locking module writes the window start period, window end period, periodic status nodes between the window start period and window end period, adjustment actions retained within the window, corresponding equipment group thermal impact events, and corresponding node associations into the same diagnostic locking window. After the diagnostic locking window is formed, the periodic status nodes within the window are arranged according to a unified detection cycle number, and the adjustment actions within the window retain their adjustment action numbers and adjustment action positions. Thus, the diagnostic locking window limits the reading range of subsequent cooling response states and blocks adjustment actions that change the direction of thermal impact transmission corresponding to the node association from entering the subsequent cooling development judgment process.

[0048] The developing module is used to read the cooling response status of the cycle status node within the diagnostic locking window, form a cooling and developing node containing the cooling response location and developing retention amount, and form a cooling and developing chain based on the node association. Specifically, in this embodiment, the developing module is used to read the cooling response status of the periodic status nodes within the diagnostic locking window, forming cooling and developing nodes that include the cooling response location and developing retention amount, and forming a cooling and developing chain based on node associations. After being written by the window locking module, the diagnostic locking window includes the window start period, window end period, periodic status nodes between the window start period and window end period, corresponding device group thermal impact events, and corresponding node associations. The developing module reads the periodic status nodes within the diagnostic locking window in ascending order of the unified detection cycle number, and determines the arrangement order of each periodic status node according to the corresponding thermal impact transmission direction of the node association.

[0049] In this embodiment, the cooling response state is the state formed after the departure-side correction increment value in the state transition amount corresponding to the periodic state node changes from a heating direction to a cooling direction. When the departure-side correction increment value is greater than zero, the corresponding departure-side thermal operation state progresses along the heating direction; when the departure-side correction increment value is less than zero, the corresponding departure-side thermal operation state progresses along the cooling direction. When the developing module reads the cooling response state of the periodic state node, it reads the departure-side correction increment value in the state transition amount corresponding to the periodic state node and compares the departure-side correction increment values ​​in adjacent unified detection cycles.

[0050] When the developing module determines the cooling response position, it reads the periodic status nodes associated with the same node in the unified detection cycle sequence within the diagnostic locking window, and reads the departure-side correction increment value in the state transition amount corresponding to the periodic status node. When the departure-side correction increment value in an adjacent unified detection cycle changes from a value greater than zero to a value less than zero, the developing module determines the unified detection cycle containing the periodic status node with the value less than zero as the cooling response position. The cooling response position is used to record the unified detection cycle in which the departure-side thermal operation state transitions from a heating direction to a cooling direction.

[0051] After determining the cooling response location, the developing module continues to read the departure-side correction increment value corresponding to the periodic status node within the subsequent unified detection cycle associated with that node, using the cooling response location as the boundary. The subsequent unified detection cycle is the detection cycle number that is later than the unified detection cycle number corresponding to the cooling response location. When the departure-side correction increment value after the cooling response location becomes greater than zero again, the developing module generates a developing retention amount based on this greater-than-zero departure-side correction increment value. The developing retention amount is used to record the cumulative heating increment amount that continues to advance along the heating direction after the cooling response has occurred. When only one greater-than-zero departure-side correction increment value is read after the cooling response location, that departure-side correction increment value is determined as the developing retention amount. When multiple greater-than-zero departure-side correction increment values ​​are read after the cooling response location, these multiple greater-than-zero departure-side correction increment values ​​are added together to form the developing retention amount.

[0052] The developing module writes the cooling response location, developing retention amount, and corresponding node associations to the same cooling and developing node. When writing to the cooling and developing node, the developing module also writes the unified detection cycle number corresponding to the cooling response location, the unified detection cycle number that forms the developing retention amount, the developing retention amount, the corresponding cycle status node, the corresponding node association, and the arrangement position within the node association. If no departure-side correction increment value greater than zero is read after the cooling response location, the developing module does not form a cooling and developing node under the corresponding node association.

[0053] After a cooling and developing node is formed, the developing module creates a cooling and developing chain based on node associations. Specifically, the developing module reads the node associations within the same equipment group's thermal impact events and reads the already formed cooling and developing nodes according to the thermal impact transmission direction corresponding to the node associations. The developing module takes the earliest cooling and developing node along the thermal impact transmission direction in the node association that has already formed a cooling and developing node as the starting cooling and developing node, and reads the next cooling and developing node sequentially along the node association. Reading sequentially along the node association means reading the corresponding cooling and developing node according to the arrangement order of the previous cycle state node, the successor cycle state node, and the subsequent cycle state node.

[0054] The developing module determines whether the cooling response position delay condition is met for the previous and subsequent cooling developing nodes. Specifically, it reads the cooling response position of the previous and subsequent cooling developing nodes. When the cooling response position of the subsequent cooling developing node is later than that of the previous cooling developing node, and the interval between the cooling response positions of the previous and subsequent cooling developing nodes is within the preset node transmission response period, the developing module continues to read the developing retention amount of the previous and subsequent cooling developing nodes.

[0055] The preset node transmission response cycle range is a range of unified detection cycles used to determine whether the response delay between adjacent cooling and developing nodes belongs to the same heat-affected zone transfer process. In this embodiment, the preset node transmission response cycle range is two to five unified detection cycles. This range is determined through historical detection data: the developing module reads the cooling response positions of historical cooling and developing nodes associated with the same node, calculates the difference in unified detection cycle numbers between adjacent cooling and developing nodes; the minimum and maximum values ​​of the differences in unified detection cycle numbers obtained from at least five historical detection data are taken to form the preset node transmission response cycle range.

[0056] After the cooling response position delay condition is met, the developing module calculates the ratio between the developing retention amount of the subsequent cooling developing node and the developing retention amount of the previous cooling developing node. The preset developing acceptance ratio range is a range of ratios used to determine whether the developing retention amount has an acceptance relationship along the node association. In this embodiment, the preset developing acceptance ratio range is 0.5 to 1.5. This range is determined through historical detection data: the developing module reads the developing retention amount of historical cooling developing nodes under the same node association, calculates the historical ratio between the developing retention amount of the subsequent cooling developing node and the developing retention amount of the previous cooling developing node, and forms the preset developing acceptance ratio range based on the minimum and maximum values ​​of at least five historical ratios.

[0057] When the ratio of the development retention at the subsequent cooling and developing node to that at the previous cooling and developing node is within a preset development acceptance ratio range, the developing module writes the previous and subsequent cooling and developing nodes into the same cooling and developing chain according to node association. When writing into the cooling and developing chain, the developing module writes the corresponding equipment group thermal impact event, node association, previous cooling and developing node, subsequent cooling and developing node, the unified detection cycle number interval between the previous and subsequent cooling and developing nodes, and the ratio between the development retention amounts. Thus, the cooling and developing chain records the chained relationship of the cooling response position being deferred along node associations and the development retention amount being accepted along node associations.

[0058] The developing module will not write the subsequent cooling and developing node into the same cooling and developing chain if the cooling response position of the subsequent cooling and developing node is not later than that of the previous cooling and developing node. The developing module will also not write the subsequent cooling and developing node into the same cooling and developing chain if the interval between cooling response positions is not within the preset node transmission response cycle. Furthermore, the developing module will not write the subsequent cooling and developing node into the same cooling and developing chain if the ratio of developing retention amounts is not within the preset developing acceptance ratio.

[0059] The path module is used to determine the current heat-affected zone transfer path between devices based on the extension of the cooling response position along the node and the connection of the developing retention along the node in the cooling and developing chain, and to form the cooling margin occupancy based on the developing retention in the current heat-affected zone transfer path between devices. Specifically, in this embodiment, the path module determines the current inter-device heat transfer path based on the deferred cooling response position along the node association and the inherited development retention amount along the node association in the cooling and developing chain. The path module reads the cooling and developing chain already formed by the developing module, and reads each cooling and developing node in the cooling and developing chain, the node association corresponding to each cooling and developing node, the cooling response position in each cooling and developing node, and the development retention amount. The path module reads the first cooling and developing node, the middle cooling and developing node, and the last cooling and developing node in the cooling and developing chain according to the heat transfer direction corresponding to the node association; when each adjacent cooling and developing node in the cooling and developing chain has met the conditions of deferred cooling response position and inherited development retention amount, the path module determines the node association path corresponding to the cooling and developing chain as the current inter-device heat transfer path. The current inter-device heat transfer path includes at least the cooling and developing nodes arranged along the heat transfer direction corresponding to the node association, the electromechanical equipment corresponding to each cooling and developing node, and the cooling response position and development retention amount in each cooling and developing node.

[0060] When the path module determines the cooling margin occupancy, it first reads the electromechanical equipment corresponding to the latest cooling and developing node along the corresponding heat impact transmission direction in the current inter-device heat impact transmission path, and identifies it as the affected electromechanical equipment. The latest cooling and developing node along the corresponding heat impact transmission direction refers to the cooling and developing node located at the end of the heat impact transmission in the current inter-device heat impact transmission path, and which has already formed a developing retention amount. The affected electromechanical equipment is the electromechanical equipment corresponding to this latest cooling and developing node. Through this reading method, the affected electromechanical equipment is determined by the node arrangement position in the current inter-device heat impact transmission path, without separately determining it based on the individual machine temperature threshold.

[0061] After identifying the affected electromechanical equipment, the path module reads the maximum cooling execution value of the affected equipment and the current cooling execution value of the unified detection cycle preceding the diagnostic locking window start period. The maximum cooling execution value is the maximum equivalent cooling output value that the affected equipment is allowed to achieve at the cooling action location, expressed as a percentage in this embodiment, with the maximum cooling execution value being 100%. The current cooling execution value is the equivalent cooling output value read by the affected equipment at the cooling action location within the unified detection cycle preceding the diagnostic locking window start period. If there is no preceding unified detection cycle for the diagnostic locking window start period, the path module reads the cooling execution value corresponding to the first sampling position within the diagnostic locking window start period as the current cooling execution value. The path module subtracts the current cooling execution value from the maximum cooling execution value to form a baseline cooling margin. The baseline cooling margin is used to record the additional cooling execution space that the affected equipment can still increase before the diagnostic locking window begins.

[0062] The path module continues to read the development retention amount of the affected electromechanical equipment at the corresponding cooling and developing node in the current heat impact transfer path between devices, and reads the cooling execution increment value between the cooling response position and the development retention amount formation position of that cooling and developing node. The development retention amount formation position is the unified detection cycle in which the departure side correction increment value with a value greater than zero used to form the development retention amount is located; when multiple departure side correction increment values ​​with values ​​greater than zero jointly form the development retention amount, the unified detection cycle in which the last departure side correction increment value involved in forming the development retention amount is located is taken as the development retention amount formation position. The cooling execution increment value is formed by subtracting the cooling execution value corresponding to the cooling response position from the cooling execution value corresponding to the development retention amount formation position, and its unit is the same as the cooling execution value, which is a percentage.

[0063] The path module generates a corresponding cooling retention value based on the ratio between the cooling execution increase and the corresponding development retention. Specifically, the path module divides the cooling execution increase by the development retention at the corresponding cooling development node of the affected electromechanical equipment to obtain the corresponding cooling retention value. The development retention adopts the temperature difference caliber of the aforementioned departure-side correction increment value, and the unit is degrees Celsius; the unit of the cooling execution increase is a percentage, therefore the unit of the cooling retention value is a percentage per degree Celsius, used to record the cooling execution increase requirement corresponding to each unit of development retention.

[0064] The path module multiplies the development retention amount at the corresponding cooling and developing node of the affected electromechanical equipment with the corresponding retention cooling value to form the initial cooling margin occupancy. The initial cooling margin occupancy records the development retention amount reaching the affected electromechanical equipment in the current heat-affected zone transfer path, increasing the occupancy of cooling execution space for the affected equipment. Since the development retention amount is in degrees Celsius and the retention cooling value is in percentages per degree Celsius, the initial cooling margin occupancy formed by multiplying the two is in percentage units, consistent with the unit of the baseline cooling margin.

[0065] After establishing the initial cooling margin occupancy, the path module compares it with the baseline cooling margin. If the initial cooling margin occupancy is not greater than the baseline cooling margin, the path module determines the initial cooling margin occupancy as the actual cooling margin occupancy. This process indicates that the cooling execution space required for the development retention in the current inter-device heat-affected zone path does not exceed the additional cooling execution space that the affected electromechanical equipment can still accommodate; therefore, the initial cooling margin occupancy is used as the actual cooling margin occupancy.

[0066] When the initial cooling margin occupancy exceeds the baseline cooling margin, the path module determines the baseline cooling margin as the cooling margin occupancy. This process indicates that the cooling execution space required for the development retention in the current heat-affected zone path between devices exceeds the additional cooling execution space that the affected electromechanical equipment can still increase. Therefore, the baseline cooling margin is used as the upper limit of the cooling margin occupancy to avoid the cooling margin occupancy exceeding the actual additional cooling execution space that the affected electromechanical equipment can increase.

[0067] After the path module generates the cooling margin occupancy, it writes the current inter-device heat impact transmission path, affected electromechanical equipment, corresponding cooling and developing nodes of the affected electromechanical equipment, developing retention amount, baseline cooling margin, corresponding retention cooling value, initial cooling margin occupancy, and cooling margin occupancy into the same path analysis record. The path analysis record serves as a data writing carrier, allowing the control module to read the current inter-device heat impact transmission path and cooling margin occupancy, and generate path segmentation intervention commands.

[0068] The joint control module is used to generate path segmentation intervention commands based on the current heat impact transmission path between devices and the cooling margin occupancy, and to update the device group heat impact event based on the periodic status nodes after execution. Specifically, in this embodiment, the control module generates path segmentation intervention commands based on the current inter-device thermal impact transmission path and cooling margin occupancy, and updates the device group thermal impact events based on the periodic status nodes after execution. The control module reads the path analysis records written by the path module, which include the current inter-device thermal impact transmission path, affected electromechanical equipment, corresponding cooling and developing nodes for the affected electromechanical equipment, developing retention, baseline cooling margin, initial cooling margin occupancy, and cooling margin occupancy. The control module reads the foremost cooling and developing node along the corresponding thermal impact transmission direction in the current inter-device thermal impact transmission path, the last cooling and developing node along the corresponding thermal impact transmission direction, and the cooling and developing nodes located between the foremost and last cooling and developing nodes.

[0069] The path segmentation intervention commands include heat output reduction commands and affected compensation cooling commands. The heat output reduction command corresponds to the electromechanical equipment corresponding to the foremost cooling and developing node along the heat impact transmission direction in the current inter-device heat impact transmission path. The control module reads the current operating load value and the preset load reduction upper limit value of the electromechanical equipment corresponding to the foremost cooling and developing node. The current operating load value is the percentage of the operating load of the electromechanical equipment corresponding to the foremost cooling and developing node within the unified detection cycle corresponding to the command. The preset load reduction upper limit value is determined based on the percentage of the operating load that the electromechanical equipment is allowed to reduce to, but not fall below, the minimum operating load value within a single unified detection cycle. The minimum operating load value is determined based on the minimum percentage of the operating load required for the electromechanical equipment to maintain the current process task. In this embodiment, the preset load reduction upper limit value is 10%, and the minimum operating load value is 40%.

[0070] The control module reads the cooling margin occupancy, baseline cooling margin, and initial cooling margin occupancy from the path analysis record. When the baseline cooling margin is greater than zero, the cooling margin occupancy is divided by the baseline cooling margin to obtain the intervention ratio. The intervention ratio is multiplied by the preset load reduction upper limit to obtain the load reduction value. The current operating load value is subtracted from the load reduction value to form the target operating load value corresponding to the heat output reduction command. When the baseline cooling margin is zero and the initial cooling margin occupancy is greater than zero, the intervention ratio is set to 1. The intervention ratio is multiplied by the preset load reduction upper limit to obtain the load reduction value. The current operating load value is subtracted from the load reduction value to form the target operating load value corresponding to the heat output reduction command. When the baseline cooling margin is zero and the initial cooling margin occupancy is zero, the intervention ratio is not calculated, the load reduction value is set to zero, and the current operating load value is set as the target operating load value corresponding to the heat output reduction command. When the target operating load value is less than the minimum operating load value of the electromechanical equipment, the minimum operating load value is used as the target operating load value. The heat output reduction instruction is written to the first cooling and developing node corresponding to the electromechanical equipment, the target operating load value, and the instruction corresponding to the unified detection cycle.

[0071] The affected compensation cooling command corresponds to the electromechanical equipment corresponding to the last cooling and developing node along the heat impact transmission direction in the current inter-device heat impact transmission path. The control module reads the current cooling execution value and the maximum cooling execution value of the electromechanical equipment corresponding to the last cooling and developing node, and also reads the cooling margin occupancy from the path analysis record. The current cooling execution value is the equivalent cooling output value of the electromechanical equipment corresponding to the last cooling and developing node within the unified detection cycle corresponding to the command, and the maximum cooling execution value is the maximum equivalent cooling output value that the electromechanical equipment is allowed to reach. The control module adds the current cooling execution value to the cooling margin occupancy to form the compensation cooling execution value; when the compensation cooling execution value is not greater than the maximum cooling execution value, the compensation cooling execution value is written into the affected compensation cooling command; when the compensation cooling execution value is greater than the maximum cooling execution value, the maximum cooling execution value is written into the affected compensation cooling command. The affected compensation cooling command is written to the electromechanical equipment corresponding to the last cooling and developing node, along with the written cooling execution value and the unified detection cycle corresponding to the command.

[0072] When there is a cooling and developing node between the foremost and last cooling and developing nodes in the current heat impact transmission path between equipment, the path segmentation intervention command also includes a path heat impact reduction command. The path heat impact reduction command corresponds to the position of the cooling and developing node between the foremost and last cooling and developing nodes. The control module reads the current cooling execution value, maximum cooling execution value, and cooling margin occupancy of the electromechanical equipment corresponding to each intermediate cooling and developing node one by one according to the arrangement order in the current heat impact transmission path between equipment; it adds the cooling margin occupancy to the current cooling execution value of the electromechanical equipment corresponding to each intermediate cooling and developing node to form the corresponding intermediate cooling execution value; when the intermediate cooling execution value is not greater than the maximum cooling execution value of the electromechanical equipment corresponding to the intermediate cooling and developing node, the intermediate cooling execution value is written into the corresponding path heat impact reduction command; when the intermediate cooling execution value is greater than the maximum cooling execution value of the electromechanical equipment corresponding to the intermediate cooling and developing node, the maximum cooling execution value is written into the corresponding path heat impact reduction command. The path receives the thermal impact reduction instruction and writes it to the corresponding intermediate cooling and developing node at the corresponding position. The written cooling execution value and instruction correspond to the unified detection cycle.

[0073] The control module writes the heat output reduction command, the path-connected heat impact reduction command, and the affected compensation cooling command into the same path segment intervention command according to the order in the current inter-equipment heat impact transmission path. If there is no cooling / developing node between the foremost and last cooling / developing node in the current inter-equipment heat impact transmission path, the control module writes the heat output reduction command and the affected compensation cooling command into the same path segment intervention command according to the order in the current inter-equipment heat impact transmission path. The path segment intervention command includes the current inter-equipment heat impact transmission path, cooling margin occupancy, the corresponding electromechanical equipment for each segment command, the target value for each segment command, and the corresponding unified detection cycle.

[0074] After the path segmentation intervention command is executed, the joint control module reads the executed periodic status nodes and the corresponding state transition values ​​within the subsequent two unified detection cycles. The joint control module reads the departure-side correction increment value of the electromechanical equipment corresponding to the foremost cooling and developing node as the executed thermal output state; it also reads the departure-side correction increment value of the electromechanical equipment corresponding to the last cooling and developing node and the change in the local cooling execution state as the executed affected state. When there are intermediate cooling and developing nodes in the current inter-device thermal impact transmission path, the joint control module reads the departure-side correction increment value of the electromechanical equipment corresponding to each intermediate cooling and developing node as the corresponding executed path acceptance state.

[0075] The control module updates the thermal impact event of the equipment group based on the executed periodic status nodes. When there are no intermediate cooling and developing nodes in the current inter-equipment thermal impact transmission path, and the incremental value of the departure side correction in the executed thermal output state is not greater than zero, and the incremental value of the departure side correction in the executed affected state is not greater than zero, the control module writes the unified detection cycle after instruction execution into the equipment group thermal impact event as the event termination cycle. When there are intermediate cooling and developing nodes in the current inter-equipment thermal impact transmission path, and the incremental value of the departure side correction in the executed thermal output state is not greater than zero, the incremental value of the departure side correction in the executed affected state is not greater than zero, and the incremental value of the departure side correction in the path-accepting state corresponding to each intermediate cooling and developing node is not greater than zero, the control module writes the unified detection cycle after instruction execution into the equipment group thermal impact event as the event termination cycle. When the incremental value of the departure side correction in the executed thermal output state is still greater than zero, the control module writes the previous periodic status node, the corresponding state transition amount, and the unified detection cycle corresponding to the instruction into the equipment group thermal impact event. When the departure-side correction increment value in the affected state after execution is still greater than zero, and the result of the local cooling execution state change is still greater than zero, the control module writes the subsequent periodic state node, the corresponding state transition amount, and the cooling margin occupancy amount into the equipment group thermal impact event. If there is an intermediate cooling and development node in the current inter-equipment thermal impact transmission path, and the departure-side correction increment value in the path-accepting state corresponding to any intermediate cooling and development node is still greater than zero, the control module writes the corresponding periodic state node and the corresponding state transition amount into the equipment group thermal impact event. Through this update process, the equipment group thermal impact event can be updated based on the periodic state nodes after the execution of the path segment intervention command, forming a closed loop of event updates from thermal impact event identification, diagnostic locking window formation, cooling and development chain formation, current inter-equipment thermal impact transmission path determination, cooling margin occupancy formation to the execution of the path segment intervention command.
