Description

Technical Field

[0001] This invention relates to the field of heating control technology, and in particular to a method for evaluating the reliability of metering in multi-source out-of-synchronous heating terminals. Background Technology

[0002] Currently, in existing heating systems using hot water storage tanks, hydraulic separators, and floor radiant heating terminals, the flow rates on the heat source side and the terminal side are separated from the actual heat release process in the room by the heat storage component. Even after the intelligent control valve is closed, the hot water storage tank can continue to supply heat to the floor coils; after the heat source-side circulation pump starts, the additional heat may also be stored in the tank initially, temporarily not causing changes in the terminal return water temperature or the indoor temperature. Simultaneously, temperature stratification forms inside the tank, and the lag in heat accumulation and release varies with the remaining stored heat.

[0003] Therefore, the sequential relationship of "valve action, flow rate change, return water temperature change, and room temperature response" that the existing heating system relies on is no longer fixed, which makes it easier for the true thermal inertia to be identified as equipment time out of step, thus resulting in low accuracy of the reliability assessment of heating terminal metering. Summary of the Invention

[0004] In view of this, in order to solve the problems caused by the existing technology, this application provides a method for evaluating the reliability of metering in multi-source out-of-step heating terminals.

[0005] In a first aspect, the present invention provides a method for evaluating the reliability of metering in multi-source out-of-synchronization heating terminals, the method comprising:

[0006] Obtain the heating parameters and heating connection relationships of the water storage tank, and arrange the heating parameters and heating connection relationships of the water storage tank according to the heat flow path to construct a heat storage decoupled heating state;

[0007] The heat storage decoupled heating state is processed in layers according to the temperature change of the water storage tank, and the heat transfer relationship of each layer of heat storage state is determined to generate a heat storage state inheritance package.

[0008] According to different heat storage states, the heat storage state inheritance package establishes a corresponding time period for heating time, determines the offset characteristic time difference that exceeds the corresponding time period for heating time, and constructs a separation package for out-of-step and heat storage hysteresis based on the offset characteristic time difference.

[0009] Multiple metering windows are established for the separation of the loss of synchronization and heat storage hysteresis, and the heat transfer relationship is verified to generate a metering reliability assessment package corresponding to each metering window.

[0010] The reliability assessment packages are summarized in chronological order, and the data is divided into different measurement windows to output the reliability assessment results.

[0011] Furthermore, the step of acquiring the heating parameters and heating connection relationships of the water storage tank, and arranging the heating parameters and heating connection relationships of the water storage tank according to the heat flow path to construct a heat storage decoupled heating state, includes:

[0012] Obtain the sensor installation locations within the heating system and establish a mapping relationship between the sensor installation locations and the heat flow path;

[0013] Based on the mapping relationship between the sensor installation location and the heat flow path, sensor measurement data is acquired according to the set sampling period, and the sensor measurement data is bound with the corresponding device local time and the data acquisition unit receiving time to construct a dual-time measurement data packet.

[0014] Furthermore, the step of acquiring the heating parameters and heating connection relationships of the water storage tank, and arranging the heating parameters and heating connection relationships of the water storage tank according to the heat flow path to construct a heat storage decoupled heating state, also includes:

[0016] The state units of the heat flow path are arranged according to the heat flow path to construct the heat storage decoupled heating state.

[0017] Furthermore, the step of stratifying the heat storage decoupled heating state based on the temperature change of the water storage tank and determining the heat transfer relationship of each layer of heat storage state to generate a heat storage state inheritance package includes:

[0018] The temperature of each measuring point is arranged according to the installation height of the sensors in the water tank, and the intensity of temperature change between adjacent measuring points is calculated, so as to determine the center height of the temperature transition layer by the intensity of temperature change.

[0019] The center height of the temperature transition layer at adjacent sampling times is compared to determine the direction of movement of the temperature transition layer, and the layer operation status is marked according to the direction of movement of the temperature transition layer.

[0020] Furthermore, the step of stratifying the heat storage decoupled heating state based on the temperature change of the water storage tank and determining the heat transfer relationship of each layer of heat storage state to generate a heat storage state inheritance package also includes:

[0021] Extract the heat storage range of the water body in the high-temperature heat storage layer and the temperature transition layer that exceeds the minimum water supply temperature at the end, and determine the remaining heat release based on the heat storage range of the water body;

[0022] Under different stratified operating conditions, the change in water tank heat and the heat dissipation of water tank are extracted from the remaining released heat, and a heat storage receiving state is generated according to the proportional relationship between the change in water tank heat and the heat dissipation of water tank.

[0023] The temperature transition layer boundary and the effective volume of the water storage tank are read, and the hysteresis range is determined based on the temperature transition layer boundary and the effective volume of the water storage tank, so as to write the operating status of each layer, the heat storage acceptance status and the hysteresis range into the heat storage status inheritance package.

[0024] Furthermore, the step of establishing corresponding time periods for heating time according to different heat storage states in the heat storage state inheritance package, determining the offset characteristic time difference exceeding the corresponding time period for heating time, and constructing a desynchronization and heat storage hysteresis separation package based on the offset characteristic time difference, includes:

[0025] Extract the water tank operating status from the heat storage state inheritance package, and establish a heat receiving sequence for the water tank operating status, so as to construct a sub-state response inheritance package according to the heat receiving sequence;

[0026] Based on the sub-state response inheritance package and the heat storage state inheritance package, the upper and lower limits of the corresponding time period of the heating time are calculated, and the offset characteristic time difference of the local time of the device corresponding to each heating event is determined.

[0027] Based on the offset characteristic time difference, each evaluation segment is marked with heat storage hysteresis events, time out-of-synchronization events, and non-separation events, and the heat storage hysteresis events, time out-of-synchronization events, and non-separation events are written into the out-of-synchronization and heat storage hysteresis separation package according to the heating event sequence.

[0028] Furthermore, the step of establishing multiple metering windows for the separation of the out-of-step and heat storage hysteresis packages, and verifying the heat transfer relationship, generates a metering reliability assessment package corresponding to each metering window, including:

[0029] Metering windows are established for the heat storage hysteresis event, time out-of-step event, and non-separation event, respectively, and the heat change corresponding to each metering window is accumulated to check the heat closure deviation of each metering window;

[0030] Based on the results of verifying the heat closure deviation of each measurement window, different types of confidence windows are established for each measurement window, and the confidence windows are sorted in chronological order to generate the measurement confidence assessment package.

[0031] Furthermore, the process of summarizing the measurement reliability assessment packages in chronological order and dividing the data into different measurement windows to output reliability assessment results includes:

[0032] Extract the start and end boundaries corresponding to each confidence window, and arrange the start and end boundaries according to a unified time axis to summarize the reliable heating range and metering confidence.

[0033] Extract the time period to be audited from the measurement reliability assessment package, and set a specified flag for the time period to be audited to generate an audit processing package;

[0034] The reliable heating range, metering reliability, and pending verification packages are written into the reliability assessment results in a unified time sequence, and the reliability assessment results are output.

[0035] In a second aspect, the present invention provides a device for evaluating the reliability of metering in multi-source out-of-synchronous heating terminals, used to implement the method for evaluating the reliability of metering in multi-source out-of-synchronous heating terminals as described in any one of the first aspects, the device comprising:

[0037] The inheritance package generation module is used to perform layered processing of the heat storage decoupled heating state according to the temperature change of the water storage tank, and determine the heat transfer relationship of each layer of heat storage state in order to generate the heat storage state inheritance package.

[0038] The separation package construction module is used to establish a corresponding time period for heating time for the heat storage state inheritance package according to different heat storage states, so as to determine the offset characteristic time difference that exceeds the corresponding time period for heating time, and construct the out-of-step and heat storage hysteresis separation package according to the offset characteristic time difference.

[0039] The reliability assessment module is used to establish multiple metering windows for the separation package of out-of-step and heat storage hysteresis, and to verify the heat transfer relationship in order to generate a metering reliability assessment package corresponding to each metering window.

[0040] The evaluation result output module is used to summarize the measurement reliability evaluation package in chronological order and divide the data into different measurement windows to output the reliability evaluation results.

[0043] The beneficial effects of the present invention are as follows: Compared with the prior art, the present invention has the following advantages:

[0044] (1) This invention obtains the heating parameters and heating connection relationships of the water storage tank, and arranges the heating parameters and heating connection relationships of the water storage tank according to the heat flow path to construct a decoupled heating state for heat storage. Then, the decoupled heating state for heat storage is processed in layers according to the temperature change of the water storage tank, and the heat transfer relationship of each layer of heat storage state is determined to generate a heat storage state inheritance package. Subsequently, a corresponding time period for heating time is established for the heat storage state inheritance package according to different heat storage states to determine the offset characteristic time difference exceeding the corresponding time period for heating time, and a separation package for out-of-step and heat storage hysteresis is constructed according to the offset characteristic time difference, thereby realizing the effective distinction between actual heat storage hysteresis and equipment time out-of-step.

[0045] (2) Based on the distinction between actual heat storage hysteresis and equipment time synchronization failure, this invention establishes multiple metering windows for the separation of synchronization failure and heat storage hysteresis, and verifies the heat transfer relationship to generate a metering reliability assessment package corresponding to each metering window. Finally, the metering reliability assessment packages are summarized in chronological order, and data is divided for different metering windows to output the reliability assessment results. This effectively avoids the technical problem of response sequence failure in the decoupling scenario of hot water storage tank and hydraulic separator, and improves the accuracy of metering reliability assessment of heating terminal.

[0056] like Figure 1 As shown, in one embodiment, a method for assessing the reliability of metering in a multi-source out-of-synchronization heating terminal includes the following steps:

[0057] Step S110: Obtain the heating parameters and heating connection relationships of the water storage tank, and arrange the heating parameters and heating connection relationships of the water storage tank according to the heat flow path to construct a heat storage decoupled heating state.

[0058] In some embodiments, the multi-source out-of-synchronous heating terminal metering reliability assessment method provided by the present invention includes the following steps in step S110:

[0059] Step S111: Obtain the sensor installation location within the heating system and establish a mapping relationship between the sensor installation location and the heat flow path.

[0060] Step S112: Based on the mapping relationship between the sensor installation location and the heat flow path, sensor measurement data is acquired according to the set sampling period, and the sensor measurement data is bound with the corresponding device local time and the data acquisition unit receiving time to construct a dual-time measurement data packet.

[0061] In some embodiments, the multi-source out-of-synchronous heating terminal metering reliability assessment method provided by the present invention further includes the following steps in step S110:

[0062] Step S113: Calculate the heat input from the heat source side and the heat taken out from the end side for each sampling interval in the dual-time measurement data packet, and write the heat input from the heat source side and the heat taken out from the end side into the heat flow path state unit.

[0063] Step S114: Arrange the state units of the heat flow path according to the heat flow path to construct the heat storage decoupled heating state.

[0064] In a specific embodiment, the multi-source out-of-synchronization heating terminal metering reliability assessment method provided by the present invention includes steps 1 to 5:

[0065] Step 1: Construct a thermal storage decoupled heating state sequence.

[0066] The system collects data on water temperature at different heights in the hot water storage tank, supply and return water temperatures and flow rates on the heat source side and the terminal side, intelligent control valve opening, circulation pump status on the heat source and terminal sides, floor surface temperature, and indoor temperature. Simultaneously, it records the local time of each device, the time the data acquisition unit receives the data, power outage recovery, sleep / wake-up, restart, and time synchronization events. Combining the tank volume, pipe height, hydraulic separator connection direction, and floor coil connection relationship, the measured values ​​are arranged according to the actual heat flow path, forming a sequence of heat storage decoupled heating states that retains the tank's stratification location, heat flow direction, and device time. This sequence includes the following sub-steps:

[0067] Sub-step 1.1: Establish the mapping between the sensor and the heat flow path.

[0068] Specifically, platinum resistance water temperature sensors are installed at 10%, 30%, 50%, 70%, and 90% of the height of the hot water storage tank; paired platinum resistance pipe temperature sensors are installed on the supply and return pipes on the heat source side, and the supply and return pipes on the terminal side; time-difference ultrasonic flow sensors are installed on the heat source side and the terminal side; Hall effect valve position sensors are installed on the intelligent control valve; AC current sensors and Hall effect speed sensors are installed on both circulating pumps; thin-film surface temperature sensors are installed on the floor surface; digital room temperature sensors are installed at representative indoor locations; and AC voltage sensors are installed in the power supply circuit to identify power outages and restore power. Furthermore, sleep / wake-up, device restart, and background time synchronization are directly read as device event records and not presented as sensor measurements.

[0069] Sub-step 1.2 generates a dual-time measurement data packet.

[0070] Specifically, the system collects measurements from each sensor at a uniform sampling period of 10-12 seconds, and adds the device's local time and the data acquisition unit's receiving time to each measurement record. During execution, the system uses the relative difference between the two clocks for the same sampling interval to identify changes in timing continuity. When the changes in timing continuity exceed the time segmentation threshold, or when events such as power outage recovery, sleep wake-up, device restart, or background time synchronization occur, a timing segment boundary is set at that sampling point.

[0071] Sub-step 1.3 generates the state unit of the heat flow path.

[0072] Specifically, the heat input at the heat source side and the heat output at the terminal side are calculated separately within each sampling interval, as expressed by:

[0073]

[0074] In the formula, For the first The heat in each sampling interval, in joules; Number the pipeline, either the heat source side pipeline or the end side pipeline; The density of water is obtained by referring to a table based on the actual water temperature, and is taken as 971-996 kg per cubic meter within the range of 30-80 degrees Celsius; The specific heat capacity of water is obtained by referring to a table based on the actual water temperature, and is taken as 4178-4197 joules per kilogram of Kelvin. The sampling interval length is expressed in seconds. This refers to the volumetric flow rate of the pipeline, expressed in cubic meters per second. The temperature difference between the supply and return water in the same pipeline is expressed in Kelvin; the three sampling locations mentioned above represent the start, mid, and end points of the interval, respectively. This formula uses a weighted integral of the start, mid, and end points, and its core is to transform the continuously changing flow rate and temperature difference within the interval into a path state with a definite heat dimension.

[0075] Sub-step 1.4: Arrange the thermal storage decoupled heating state sequence.

[0076] Specifically, firstly, each state unit is arranged according to the actual heat flow sequence: "heat source side water supply, heat source side flow rate, water tank inlet, water tank five-layer temperature, water tank end-side outlet, end-side flow rate, intelligent control valve, floor coil, floor surface, and indoor environment." Then, within each state unit, the following information is retained: heat in the heat source side interval, heat in the end-side interval, five-layer water temperature, valve opening, circulating pump current and speed, floor surface temperature, indoor temperature, local equipment time, data acquisition time, and timing segment boundaries. This ultimately forms a heat storage decoupled heating state sequence that can be used to identify the water tank's stratification location and heat reception direction.

[0077] Step S120: Based on the temperature change of the water storage tank, the heat storage decoupled heating state is processed in layers, and the heat transfer relationship of each layer of heat storage state is determined to generate a heat storage state inheritance package.

[0078] In some embodiments, the multi-source out-of-synchronous heating terminal metering reliability assessment method provided by the present invention includes the following steps in step S120:

[0079] Step S121: Arrange the temperature of each measuring point according to the installation height of the sensors in the water storage tank, and calculate the intensity of temperature change between adjacent measuring points, so as to determine the center height of the temperature transition layer by the intensity of temperature change.

[0080] Step S122: Compare the center height of the temperature transition layer corresponding to adjacent sampling times to determine the moving direction of the temperature transition layer, and mark the layer operation status according to the moving direction of the temperature transition layer.

[0081] In some embodiments, the multi-source out-of-synchronous heating terminal metering reliability assessment method provided by the present invention further includes the following steps in step S120:

[0082] Step S123: Extract the water heat storage range in the high-temperature heat storage layer and temperature transition layer that exceeds the minimum water supply temperature at the end, and determine the remaining heat release based on the water heat storage range.

[0083] Step S124: Under different stratified operation states, extract the change in water tank heat and the heat dissipation of water tank from the remaining released heat, and generate the heat storage receiving state according to the proportional relationship between the change in water tank heat and the heat dissipation of water tank.

[0084] Step S125: Read the temperature transition layer boundary and the effective volume of the water storage tank, and determine the hysteresis range based on the temperature transition layer boundary and the effective volume of the water storage tank, so as to write the operating status of each layer, the heat storage acceptance status and the hysteresis range into the heat storage status inheritance package.

[0085] In a specific embodiment, the multi-source out-of-synchronous heating terminal metering reliability assessment method provided by the present invention includes step 2, identifying the layered state and heat transfer relationship of the hot water storage tank. The heat storage decoupled heating state sequence formed in step 1 is divided into a high-temperature heat storage layer, a temperature transition layer, and a low-temperature waiting-to-heat layer according to the temperature changes at different heights of the water tank. The movement direction of the temperature transition layer is determined, and combined with the heat input from the heat source side and the heat extracted from the terminal side, the state of the water tank being identified as charging, releasing, simultaneously charging and releasing, or static heat preservation is identified. Further, the remaining releaseable heat in the water tank, the proportion of heat input received by the water tank, the proportion of heat extraction at the terminal undertaken by the water tank, and the hysteresis range required for the temperature transition layer to reach the terminal outlet are determined for each state, forming a heat storage state inheritance package containing the original heating state sequence, including the following sub-steps:

[0086] Sub-step 2.1: Divide the water tank into temperature layers and locate the temperature transition layer.

[0087] Specifically, based on the installation height of the five platinum resistance water temperature sensors, the temperature measurement points are arranged from the bottom to the top of the water tank, and the intensity of temperature change between adjacent measurement points is calculated. During execution, a temperature gradient weighted method is used to determine the center height of the temperature transition layer, expressed as:

[0088]

[0089] In the formula, For the first The temperature transition layer center height at each sampling time is expressed in meters. Number the water temperature measuring points; This represents the total number of water temperature measuring points, and is set to 5. and The first The and the first The height of each measuring point from the bottom of the water tank is in meters. and These are the water temperatures at two adjacent measuring points, in degrees Celsius. The highest water temperature among the five measuring points; The lowest water temperature among the five measuring points; The temperature gradient enhancement index is dimensionless and ranges from 1.8 to 2.0. When the water tank is tall or the temperature stratification is clear, a value close to 2.0 is used. In addition, the height range where the temperature change intensity of adjacent measuring points reaches 70-82% of the maximum change intensity is designated as the temperature transition layer. The area above the temperature transition layer is designated as the high-temperature heat storage layer, and the area below it is designated as the low-temperature waiting-to-heat layer.

[0090] Sub-step 2.2: Determine the direction of movement of the temperature transition layer and the operating status of the water tank.

[0091] Specifically, firstly, the center height of the temperature transition layer is compared between adjacent sampling times. When the increase in center height exceeds 0.18% to 0.22% of the water tank height, the temperature transition layer is determined to have moved upwards; when the decrease in center height exceeds this range, the temperature transition layer is determined to have moved downwards; if it does not exceed this range, the temperature transition layer is determined to remain stationary. This range is used to exclude false movements caused by fluctuations in platinum resistance temperature measurement; 0.22% is used when there is significant internal disturbance in the water tank.

[0092] Subsequently, the direction of temperature transition layer movement is used in conjunction with the heat in the heat source side and the heat in the end side. When the heat input from the heat source side is greater than the heat output from the end side and the average temperature of the water tank rises, it is marked as a charging state; when the heat output from the end side is greater than the heat input from the heat source side and the average temperature of the water tank decreases, it is marked as a releasing state; when heat flows on both the heat source side and the end side, and temperature rises and falls occur near different pipes, it is marked as a charging and releasing state; when the heat in both sides is lower than the effective measurement lower limit of their respective heat meters, and the temperature transition layer is maintained, it is marked as a static heat preservation state. Finally, all four water tank operating states are written into the stratified operating state package.

[0093] Sub-step 2.3: Calculate the remaining releaseable heat and the heat receiving ratio.

[0094] Specifically, water bodies in the high-temperature heat storage layer and temperature transition layer that are above the minimum available water supply temperature at the end are included in the available heat storage range. The minimum available water supply temperature at the end is obtained from the floor radiant heating design parameters or the current water supply temperature control curve.

[0095] In this embodiment, the expression for the remaining releaseable heat after deducting the expected heat loss is:

[0096]

[0097] In the formula, Remaining flammable heat, measured in joules; The effective heat extraction coefficient is set at 0.90-0.94, with 0.90 used when there is a small amount of stagnant water near the water tank connection. The density of water; The specific heat capacity of water; A set of water layer numbers within the available thermal storage range; For the first The effective volume of each water layer is expressed in cubic meters. For the first The temperature of each water layer; The lowest available water supply temperature at the end; The total heat transfer coefficient of the water tank is expressed in watts per square meter Kelvin and is obtained from the parameters of the water tank insulation layer or from a shutdown cooling test. This refers to the outer surface area of ​​the water tank, in square meters. This represents the average temperature of the water tank. The temperature of the equipment room where the water tank is located; This represents the upper limit of the hysteresis between the temperature transition layer and the final outlet, expressed in seconds. It should be noted that in extreme cases, if... If the value is less than 0, it should be considered as 0.

[0098] In this embodiment, under the charging state, the ratio of the sum of the increase in heat in the water tank and the heat dissipation of the water tank to the heat input on the heat source side is used as the heat source input acceptance ratio; under the heat release state, the ratio of the decrease in heat in the water tank minus the heat dissipation of the water tank to the heat taken out on the end side is used as the end heat take-out acceptance ratio; under the simultaneous charging and releasing state, two ratios are calculated based on the actual heat flow path between the heat source inlet, water tank stratification, and end outlet; under the static heat preservation state, both ratios are recorded as zero, and the remaining releaseable heat is retained for inheritance in subsequent heat release states.

[0099] Sub-step 2.4: Determine the hysteresis range of the temperature transition layer and form the inheritance package.

[0100] Specifically, based on the effective volume of the water tank between the upper and lower boundaries of the temperature transition layer and the terminal outlet pipe, the lower and upper limits of the hysteresis are obtained by dividing them by the upper and lower boundaries of the effective flow rate at the terminal side within the most recent 5-6 sampling intervals. In the heat charging state, the heat transfer path from the heat source inlet to the temperature transition layer is used; in the heat release state, the release path from the temperature transition layer to the terminal outlet is used; in the simultaneous charging and releasing state, the hysteresis ranges of the heat source input and terminal release are retained respectively; in the static heat preservation state, the current position of the temperature transition layer is retained, and the hysteresis range is extended until the terminal circulating pump restarts and is recalculated. Finally, the four water tank operating states, the two heat transfer ratios, and their respective hysteresis ranges are all written into the heat storage state inheritance package.

[0101] Step S130: Establish heating time corresponding time periods for the heat storage state inheritance package according to different heat storage states, determine the offset characteristic time difference exceeding the corresponding time period of heating time, and construct the out-of-step and heat storage hysteresis separation package based on the offset characteristic time difference.

[0102] In some embodiments, the multi-source out-of-synchronous heating terminal metering reliability assessment method provided by the present invention includes the following steps in step S130:

[0103] Step S131: Extract the water tank operating status from the heat storage state inheritance package, and establish a heat receiving sequence for the water tank operating status, so as to construct a sub-state response inheritance package according to the heat receiving sequence.

[0104] Step S132: Based on the sub-state response inheritance package and the heat storage state inheritance package, calculate the upper and lower limits of the corresponding time period of the heating time, and determine the offset characteristic time difference of the local time of the device corresponding to each heating event.

[0105] Step S133: Mark the heat storage hysteresis event, time out-of-synchronization event, and non-separation event for each evaluation segment according to the offset characteristic time difference, and write the heat storage hysteresis event, time out-of-synchronization event, and non-separation event into the out-of-synchronization and heat storage hysteresis separation package according to the heating event sequence.

[0106] In a specific embodiment, the multi-source out-of-synchronous heating terminal metering reliability assessment method provided by the present invention, step 3, establishes the heating response inheritance relationship that changes with the heat storage state, such as... Figure 2 As shown. The heat storage state inheritance package formed in step 2 is processed separately according to different heat storage states. When in the charging state, the changes in flow and temperature on the heat source side are first attributed to the heat storage increase process of the water tank, and the immediate response of the terminal return water temperature is not required. When in the heat release state, the continuous heating after the control valve is closed or the circulation pump on the heat source side stops is attributed to the release process of the remaining heat in the water tank. When in the simultaneous charging and releasing state, the share of heat source input and water tank storage in the terminal heating is determined respectively. When in the static heat preservation state, only the hysteresis caused by the natural heat dissipation of the water tank and the slow migration of stratification is retained. Finally, the dynamic response time period allowed for each heating event is formed, and the time difference that can be explained by the response time period is attributed to the heat storage hysteresis. The time difference that exceeds the response time period and meets the continuous offset characteristics of the equipment clock is attributed to the time out of step, forming a separation package of out of step and heat storage hysteresis, including the following sub-steps:

[0107] Sub-step 3.1: Establish the sub-state thermal response inheritance chain.

[0108] Specifically, firstly, a heat transfer sequence is established according to the water tank operating status in the heat storage state inheritance package. For the charging state, the following are recorded sequentially: the operation of the circulation pump on the heat source side, the change in flow rate on the heat source side, the change in water supply temperature on the heat source side, the expansion of the high-temperature heat storage layer in the water tank, the movement of the temperature transition layer, the change in outlet water temperature on the terminal side, and the change in return water temperature on the terminal side. All heat source input before the temperature transition layer reaches the terminal outlet is inherited into the water tank heat storage increase process. For the heat release state, the heat release inheritance starts at the moment the control valve closes or the moment the circulation pump on the heat source side stops. The remaining releaseable heat in the water tank, the continuous flow rate on the terminal side, the continuous heat release from the floor surface, and the delayed change in indoor temperature are arranged into a heat release response inheritance chain.

[0109] For simultaneous charging and discharging, based on the heat source input acceptance ratio and the terminal heat extraction acceptance ratio, the heat source input is allocated to the water tank storage branch and the terminal immediate heating branch, while the terminal heat extraction is allocated to the heat source immediate acceptance branch and the water tank storage acceptance branch. Each branch retains its own start time and heat share. For static insulation, the mandatory inheritance relationship from valve action to terminal temperature change is eliminated; only the natural heat dissipation from the water tank, the slow stratification and migration of the water tank, and the release of residual heat from the floor are retained. All four inheritance chains carry the inheritance package from the original heat storage state, and the deletion of heat source-side events that do not immediately generate a terminal response is prohibited.

[0110] Sub-step 3.2: Determine the dynamic response period for each heating event.

[0111] Specifically, the starting point of the heat source-side circulating pump, the change in the heat source-side supply water temperature, the action of the intelligent control valve, and the stopping of the heat source-side circulating pump are taken as the starting points of the heating events. Based on the temperature transition layer hysteresis range, the effective volume of the terminal pipeline, the flow boundary of the terminal side, and the heat capacity of the floor and room, the upper limit of the allowable time period for changes in the terminal return water temperature, floor surface temperature, and indoor temperature is calculated. The expression is:

[0112]

[0113] In the formula, For the first The heating incident caused the first The upper limit of the response time period, in seconds; These represent the terminal return water temperature response, floor surface temperature response, or indoor temperature response, respectively. This represents the upper limit of the temperature transition layer hysteresis, in seconds. The effective volume of the pipeline from the water tank's outlet to the target temperature measurement location is expressed in cubic meters. This represents the lower boundary of the effective flow rate at the terminal side, expressed in cubic meters per second. Number the heat transfer links; For heat to reach the first The number of heat transfer stages before the response location; For the first The equivalent heat capacity of each heat transfer link, in joules per Kelvin; For the first The equivalent thermal conductivity of each heat transfer link is expressed in watts per Kelvin. For the first The threshold value for identifiable temperature change in each heat transfer stage is 0.18-0.22 Kelvin, with 0.18 Kelvin used when the platinum resistance sensor has high accuracy. The first after the heating incident continued to act The stable temperature change amplitude achievable at each heat transfer stage, measured in Kelvin, is determined by the supply and return water temperature difference and the heat transfer ratio. This formula is used to sequentially accumulate the water tank stratification migration time, pipeline transportation time, and the first-order thermal inertia time of the floor and room. The lower limit of the response time period is calculated using the lower limit of the temperature transition layer hysteresis and the upper boundary of the effective flow rate at the end side.

[0114] In this embodiment, the charging state uses the dynamic response time period from the heat source input event to each response location; the heat release state uses the remaining releaseable heat divided by the sum of the terminal heat extraction power and the water tank heat dissipation power to obtain the continuous release time period of the water tank; the simultaneous charging and discharging state forms the heat source instantaneous response time period and the water tank storage response time period respectively; the static heat preservation state only forms the natural heat dissipation time period and the stratified migration time period, and the last four types of time periods are all written into the dynamic response time period package.

[0115] Sub-step 3.3 separates heat storage hysteresis and equipment time synchronization failure.

[0116] Specifically, for each heating event, the response time difference represented by the device's local time is calculated. When the response time difference is between the lower and upper limits of the response period for that heating event, it is marked as the heat storage hysteresis time; when the response time difference exceeds the response period, the directional out-of-bounds time from the response time difference to the nearest response period boundary is calculated. For 5-6 consecutive out-of-bounds events of the same device, the continuous offset dispersion of the directional out-of-bounds time is calculated, expressed as:

[0117]

[0118] In the formula, For the first The device in the The continuous offset dispersion within each evaluation segment, in seconds; This is the set of event numbers for the device that exceeded the dynamic response period within the evaluation segment; Number the boundary crossing incidents; The weight of an out-of-bounds event is the reciprocal of the width of the dynamic response period of the event. The narrower the dynamic response period, the greater the weight of the out-of-bounds event. This refers to the time of directional boundary crossing, in seconds. This is the weighted average of all out-of-bounds times with directional deviations, expressed in seconds.

[0119] In this embodiment, when the continuous offset dispersion does not exceed 18-22% of the unified sampling period, and the positive and negative directions of all directional out-of-bounds times are consistent, the weighted average value and the dispersion range are marked as the continuous time out-of-step range. The aforementioned dispersion threshold is used to accommodate normal fluctuations in valve execution and data acquisition times; 18% is used when the repeatability of field equipment actions is high. Events that do not meet the heat storage hysteresis determination criteria or the continuous time out-of-step determination criteria are marked as temporarily inseparable events, and the original dynamic response period and directional out-of-bounds time are retained, without being forcibly classified into any category.

[0120] Sub-step 3.4 forms a separation package for step loss and heat storage hysteresis.

[0121] Specifically, firstly, according to the heating event number, heat storage lag events are written into the heat storage inheritance list, continuous time synchronization failure events are written into the clock correction list, and temporarily inseparable events are written into the interval retention list. The heat storage inheritance list retains the heat storage status, heat absorption share, lower and upper limits of the response time period; the clock correction list retains the equipment number, timing segment boundary, synchronization failure direction, and continuous time synchronization failure range; the interval retention list retains the dynamic response time period, directional boundary crossing time, and the reason for non-separation. Finally, the three lists are packaged together with the original heat storage status inheritance package and output.

[0122] Step S140: Establish multiple metering windows for the separation of out-of-step and heat storage hysteresis packages, and verify the heat transfer relationship to generate a metering reliability assessment package corresponding to each metering window.

[0123] In some embodiments, the multi-source out-of-synchronous heating terminal metering reliability assessment method provided by the present invention includes the following steps in step S140:

[0124] Step S141: Establish metering windows for heat storage hysteresis events, time out-of-synchronization events, and non-separation events respectively, and accumulate the heat change corresponding to each metering window to check the heat closure deviation of each metering window.

[0125] Step S142: Based on the results of verifying the heat closure deviation of each measurement window, establish different types of confidence windows for each measurement window, and sort the confidence windows in chronological order to generate a measurement confidence assessment package.

[0126] In a specific embodiment, the multi-source out-of-synchronization heating terminal metering reliability assessment method provided by the present invention, step 4, forms a metering reliability window that considers heat storage inheritance, such as... Figure 3As shown. The separation package for time loss and heat storage hysteresis formed in step 3 is processed according to the separation results. For time periods where the time loss can be clearly determined, the equipment time is corrected and a definite metering window is formed; for time periods where the time loss range and the heat storage hysteresis range partially overlap, the overlapping boundary is retained and an interval metering window is formed; for time periods where the two cannot be separated at all, no forced time correction is performed, and a metering window to be verified is formed. Subsequently, the connection between the heat source side input, water tank heat storage change, terminal side heat extraction and continuous floor heat release are verified respectively to form a metering reliability assessment package containing a definite reliability window, an interval reliability window and a window to be verified, including the following sub-steps:

[0127] Sub-step 4.1: Construct three types of measurement windows based on the time separation results.

[0128] Specifically, firstly, the heat storage inheritance list, clock correction list, and interval retention list in the separation package of out-of-step and heat storage hysteresis are read. For devices with continuous time out-of-step range in the clock correction list, the local time of the device is corrected using the center value of the continuous time out-of-step range, and the allowable error of the corrected time is limited by the continuous offset dispersion. The corrected heat source side input, water tank stratification change, terminal side heat extraction, and floor heat release records are assigned to a unified start and end time to form a defined metering window.

[0129] For records where the continuous time synchronization range and the heat storage hysteresis period partially overlap, a single correction value is not selected. Instead, the lower limit of the left boundary, the upper limit of the left boundary, the lower limit of the right boundary, and the upper limit of the right boundary are retained to form a boundary interval metering window. For records within the interval retention list where time synchronization and heat storage hysteresis cannot be separated, the local device time and the data acquisition time are maintained, and forced translation is not performed. An uncalibrated window is formed according to the time limit from the start of the heating event to the upper limit of the dynamic response period. In addition, all three types of metering windows carry the heat storage status, the remaining releaseable heat, and the heat reception ratio.

[0130] Sub-step 4.2: Verify the degree of heat reception closure within the metering window.

[0131] Specifically, for each metering window, the heat input from the heat source side and the heat taken out from the terminal side are accumulated. The change in heat storage in the water tank is calculated based on the temperature changes of each temperature layer in the water tank at the start and end of the window. The change in heat storage in the floor is calculated based on the equivalent heat capacity of the floor and the change in the floor surface temperature. The heat dissipation of the water tank and the heat released from the floor into the room are calculated using the total heat transfer coefficient of the water tank, the equivalent thermal conductivity from the floor to the room, and the response duration.

[0132] In this embodiment, the expression for the heat closure deviation rate of the metering window is:

[0133]

[0134] In the formula, The thermal closure deviation rate is dimensionless. Number the metering window; The heat input to the heat source side within the window is measured in joules. Heat is extracted from the inner end side of the window, measured in joules. This represents the change in heat storage in the water tank, expressed in joules. A positive value is taken when the heat storage in the water tank increases, and a negative value is taken when the heat storage in the water tank decreases. This refers to the heat lost from the water tank to the equipment room, measured in joules. This represents the change in floor heat storage, expressed in joules. A positive value is used when floor heat storage increases, and a negative value is used when floor heat storage decreases. This represents the heat released from the floor into the room, measured in joules.

[0135] In this embodiment, the heat closure judgment threshold is set at 8-9%. When the water tank temperature measurement points are dense and the floor structure parameters are clear, the threshold is set at 8%. When the floor's equivalent heat capacity is obtained from the design data, the threshold is set at 9%. The metering window is determined to calculate only one heat closure deviation rate. The boundary interval metering window traverses the sampling times within the four boundary ranges to form the lower limit of the heat closure deviation rate, the upper limit of the heat closure deviation rate, the lower limit of heat calculation, and the upper limit of heat calculation. The uncalibrated window only calibrates the heat receiving direction.

[0136] Sub-step 4.3 forms three types of confidence windows.

[0137] Specifically, firstly, for the determined metering window, if the heat closure deviation rate does not exceed the heat closure judgment threshold, the determined metering window will be transferred to the determined reliable window; if the heat closure deviation rate exceeds the heat closure judgment threshold, the determined metering window will be transferred to the pending verification window, and the location of the heat source side, water tank side, terminal side or floor side where the connection interruption occurred will be recorded.

[0138] For boundary interval measurement windows, if the upper limit of the heat closure deviation rate does not exceed the heat closure judgment threshold, both the lower and upper limits of heat calculation are written into the interval confidence window. If the lower limit of the heat closure deviation rate does not exceed the heat closure judgment threshold but the upper limit exceeds the heat closure judgment threshold, it is also included in the interval confidence window, but a boundary sensitivity marker is added. If the lower limit of the heat closure deviation rate exceeds the heat closure judgment threshold, the boundary interval measurement window is transferred to the verification window. Among them, the uncalibrated verification window is directly retained as the verification window, and a marker indicating that time out-of-sync and heat storage hysteresis are inseparable is added.

[0139] Sub-step 4.4: Form the measurement reliability assessment package.

[0140] Specifically, the reliable window, interval reliable window, and window to be verified are determined according to a unified time sequence. The reliable window records the start and end times after correction, the determined heat value, and the heat closure deviation rate; the interval reliable window records four time boundaries, the lower limit of heat calculation, the upper limit of heat calculation, and boundary sensitivity markers; the window to be verified records the range of uncalibrated times, the location of interruption, the reason for inseparability, and the equipment requiring verification. Finally, the three types of windows, along with the water tank's heat storage status, heat receiving ratio, remaining releasable heat, and heat storage hysteresis range, are packaged together to form a metrological reliability assessment package.

[0141] Step S150: Summarize the measurement reliability assessment packages in chronological order and divide the data into different measurement windows to output the reliability assessment results.

[0142] In some embodiments, the multi-source out-of-synchronous heating terminal metering reliability assessment method provided by the present invention includes the following steps in step S150:

[0143] Step S151: Extract the start and end boundaries corresponding to each confidence window, and arrange the start and end boundaries according to a unified time axis to summarize the reliable heating range and metering confidence.

[0144] Step S152: Extract the time period to be audited from the measurement reliability assessment package and set a specified flag for the time period to be audited to generate the processing package to be audited.

[0145] Step S153: Write the reliable heating range, metering reliability, and pending verification package into the reliability assessment results in a uniform time sequence, and output the reliability assessment results.

[0146] In a specific embodiment, the multi-source out-of-synchronization heating terminal metering reliability assessment method provided by the present invention includes step 5, outputting the heating terminal metering reliability assessment result. The metering reliability assessment package formed in step 4 is summarized in chronological order. For the determined reliable window, the corrected metering result is retained and included in the effective metering period; for the interval reliable window, the heating range defined by the time overlap boundary is output, and the uncertainty caused by water tank stratification changes is indicated; for the window to be verified, it is stopped for precise calculation, and the verification objects of water tank stratification status, circulating pump status, control valve status, and equipment clock are output. Finally, a multi-source out-of-synchronization heating terminal metering reliability assessment result is formed, consisting of a reliable metering period, an interval reliable period, a period to be verified, heat storage hysteresis, time out-of-synchronization range, anomaly source, and verification object, including the following sub-steps:

[0147] Sub-step 5.1: Establish a list of non-repeating measurement periods.

[0148] Specifically, firstly, the start and end boundaries of the determined confidence window, the interval confidence window, and the window to be verified are extracted and arranged according to the unified time axis of the data acquisition device. With the constraint that each measurement record should only be assigned to one time period, measurement records that have completed clock correction and passed the heat closure check are assigned to the determined confidence time period; measurement records whose affiliation can only be determined within the time overlap boundary are assigned to the interval confidence time period; and measurement records whose time synchronization loss and heat storage hysteresis cannot be separated, or which have not passed the heat closure check, are assigned to the period to be verified. Finally, adjacent time periods with the same category and heat storage status are merged, while adjacent time periods with different categories retain independent boundaries to prevent repeated accumulation of heat supply.

[0149] Sub-step 5.2: Summarize the reliable heating range and the reliability of the measurement.

[0150] Specifically, the determined reliable time period uses the corrected determined heating supply, the reliable time period of the interval uses the lower limit and upper limit of heating supply, and the heating supply of the period to be verified is not included in the accurate settlement.

[0151] In this embodiment, the expression for the terminal measurement reliability index is:

[0152]

[0153] In the formula, This is a dimensionless index representing the reliability of terminal measurements. Number the time period; For the first The duration of each time period, in seconds; and The first The lower and upper limits of heating supply for each reliable time period in each interval; A set of reliable time period numbers for the interval; To determine the set of reliable time period numbers; To determine the thermal closure deviation rate for a reliable time period; and These represent the lower and upper limits of the thermal closure deviation rate for the reliable time period of the interval, respectively. The interval confidence reduction factor has a value of 0.92-0.95, and is set to 0.92 when the time overlap boundary is wide. This is the set of time periods to be verified. The reliable time period within an interval is the average duration formed by four time boundaries. This formula simultaneously considers the proportion of effective measurement time, the degree of heat closure, and the width of heat supply within the interval. The time periods to be verified are only included in the total duration and do not contribute to the reliability.

[0154] Sub-step 5.3 generates a checklist for the period to be reviewed.

[0155] Specifically, a stop precise settlement mark is set for each pending verification period. When the water tank layer boundary cannot be determined, the five platinum resistance water temperature sensors, the water tank connection position, and the temperature transition layer movement record are listed as layer verification objects. When the circulation pump status and flow connection relationship are interrupted, the AC current sensor, Hall speed sensor, and circulation pump start / stop record are listed as pump status verification objects. When the intelligent control valve action and the terminal flow connection relationship are interrupted, the Hall valve position sensor, valve actuator, and valve position record are listed as valve status verification objects. When the continuous time offset cannot be determined, the equipment real-time clock, equipment local time, data acquisition receiver receiving time, and time synchronization record are listed as clock verification objects, and each verification object is bound to a unique pending verification period and anomaly source.

[0156] Sub-step 5.4 generates the reliability assessment results of multi-source out-of-synchronization heating terminal metering.

[0157] Specifically, firstly, the reliable time period and the determined heat supply, the reliable time period of the interval and the upper and lower limits of the heat supply, the time period to be verified and the stop settlement mark are written into the evaluation results in a unified time order; at the same time, the terminal metering reliability index, the range of water tank heat storage hysteresis, the range of equipment continuous time out of step, the uncertain part of the heat supply caused by the change of water tank stratification, the location of heat receiving interruption, the source of anomalies and the objects of on-site verification are written into the results, and finally, a multi-source out-of-step heating terminal metering reliability evaluation result can be directly used for heating settlement review, metering verification and equipment time calibration.

[0163] The reliability assessment module is used to establish multiple metering windows for the separation of out-of-step and heat storage hysteresis packages, and to verify the heat transfer relationship in order to generate a metering reliability assessment package corresponding to each metering window.
