[0046] See also Figure 1-Figure 3 , a heating configuration and control method, comprising the following steps:

[0047] Step A: Obtain the temperature data of the heating season and select the lowest sampled temperature, and then calculate the control quantity of the air heat source pump according to the lowest sampled temperature;

[0048] Step A1: Obtain daily outdoor temperature data during a heating season in the area where the building is located;

[0049] Step A2: Divide the heating season into the early cold period, the severe cold period and the late cold period;

[0050] Step A3: Select the lowest outdoor temperature during the first cold period and the last cold period in the period and mark it as T 低；

[0051] Step A4: According to the outdoor temperature T 低 Calculate the maximum hourly steam consumption for the day and mark it as L max , where L max Can L max To calculate the degree of dispersion, we can count all samples of temperature T collected on that day and calculate the variance, as follows:

[0052]

[0053] Among them, LS² is the variance of steam consumption on that day, T is the average temperature on that day, and x is the temperature sample on that day.

[0054] Therefore, the discrete degree of steam consumption on that day can be calculated according to the LS² formula, and then the T 低 The calculated L max Compare with LS²;

[0055] If L maxThe difference with LS² is large, which is indicated by the temperature and temperature difference of the day, indicating that the T 低 There may be problems with inaccurate collection, so you can reselect another time to collect and keep L max Maintained within normal range with LS².

[0056] In fact, L max The difference with LS² is that the objective conditions when taking the comprehensive daily temperature and temperature difference include

[0057] Geographical factors: For the vast plateau and the temperate continental climate regions associated with the plateau (including deserts, forests, basins and other geographical environments), the difference between the highest and lowest temperatures of the day is large, and the temperature data taken is highly random, so there is L max The problem of large difference with LS² calculation can be solved by collecting more temperature samples, and then performing staged sampling according to a certain period (such as 4-6 am in the morning, 6-8 am in the morning, 8-10 am in the morning, 10-12 pm, 12-2 pm, 2-4 pm in the afternoon, 4-6 pm in the evening, 6-8 pm, 8-10 pm at night, 10-12 pm, 12-4 am), and then performing L² calculation within the staged sampling interval. max Calculate with LS² and finally select one or more L in each interval max Merge with LS² result to the L of the day max Calculate with LS² to reduce L max Difference range from LS², improve L max Accuracy with LS²;

[0058] Step A5: According to the size of the steam consumption L max Calculate the air heat source pump configuration load and mark it as Q. The calculation formula for Q is Q=L max *2.51*277.8;

[0059] Step A6: Collect the equipment heating performance coefficient according to the air heat source pump manufacturer's manual and mark it as COP 样本 ;

[0060] Step A7: Configure the load Q and equipment heating performance coefficient COP according to the air heat source pump 样本 Determine the number of air heat source pumps;

[0061] Step B: The intelligent control module calculates the optimal cost selection scheme based on the control quantity of the air heat source pump and determines the selection of the air heat source and / or municipal thermal steam heat source mode;

[0062] Step B1: Collect physical data of each module through the intelligent control module and calculate the unit GJ heat of the air heat source pump and the unit GJ heat of the municipal steam;

[0063] Step B2: Calculate the cost per GJ of heat from the air heat source pump and express it as A;

[0064] Step B3: Calculate the municipal steam unit GJ heat and express it as B;

[0065] Step B4: Calculate and compare the usage costs of A and B. Since Q = Lmax*2.51*277.8, the steam consumption can be calculated as Lmax=697.278 / Q. Figure 5 The heat consumption can be calculated from the steam consumption, specifically:

[0066] At room temperature, the specific heat capacity of water vapor is 43.4m³ / kg. From the relationship between specific heat capacity and heat, Q=CMδT, the heat Q of the same mass (i.e. the same steam volume) can be obtained as:

[0067] Qa=43.4*M*697.278 / Q, Qb=43.4*M*697.278 / Q,

[0068] Among them, M is the same, and step A7: Determine the number of air heat source pumps according to the air heat source pump configuration load Q and the equipment heating performance coefficient COP sample. It can be seen that LMAXA and LMAXB are different, so the calculated results of A and B are different.

[0069] Step B5: Compare the relationship between A and B and the usage cost and select the air heat source and / or municipal thermal steam heat source mode accordingly.

[0070] As another embodiment of the present invention: the present application can also perform dual heat source heating, specifically,

[0071] The operation mode includes steps

[0072] Step S1: According to the air heat source pump under different outdoor environments and indoor temperature requirements during the heating season, the economic efficiency of air heat source pump heating and municipal steam is divided into air heat source pump heating mode, municipal steam heating mode, and air heat source pump and municipal steam dual heat source heating mode;

[0073] Step S2: Obtain the heating performance coefficient of the air heat source pump under different outdoor environments from the heat pump manufacturer's sample manual;

[0074] Step S3: input the heating coefficient COP sample in the air heat source pump sample manual into the intelligent control module;

[0075] Step S4: inputting the steam unit price into the intelligent control module;

[0076] Step S5: inputting the electricity price of the area where the building is located into the intelligent control module;

[0077] Step S6: Determine the target indoor temperature T of the building 室内 .

[0079] Indoor target temperature T 目标 It is the temperature value recommended by the national standard, generally 20 degrees;

[0080] Outdoor ambient temperature T 室外 Acquired through outdoor weather stations;

[0081] Actual indoor temperature T 实际 Acquired through indoor temperature sensor;

[0082] Air heat source pump sample heating coefficient COP 样本 Obtained from the manufacturer's catalog brochure;

[0083] Theoretically, the cost of air heat source pump per GJ of heat is A 计算 It is automatically calculated by the intelligent control module, and the calculation formula is the theoretical amount of electricity required for the air heat pump to heat 1GJ of heat multiplied by the corresponding electricity price;

[0084] In fact, the cost of air heat source pump per GJ of heat is A 实际 It is automatically calculated by the intelligent control module, and the calculation formula is the power required by the air heat pump to heat 1GJ of heat multiplied by the corresponding electricity price;

[0085] The cost of municipal steam per GJ of heat is represented by B, which is automatically calculated by the intelligent control module using the steam price divided by 2.51;

[0086] Operation Mode:

[0087] Under the outdoor ambient temperature Toutdoor, compare the costs of A and B, and then select the corresponding heating mode according to the cost, specifically:

[0088] Case 1: When A calculated > B, the air heat source pump heating mode is enabled. When the system is running and the indoor temperature remains stable, if T actual > T target, and A actual > A calculated > B, the air heat source pump heating mode continues to run and ensures continuous and stable heating. Even after T actual > T target, continuous heating needs to be guaranteed because heat will continue to be lost due to seasons and temperature reasons during the actual working process. External energy must be supplemented to ensure the normal operation of the heating, so continuous heating is required.

[0089] Case 2: When A calculated > B, the air heat source pump heating mode is enabled. When the system is running and the indoor temperature remains stable, if T actual < T target, and A actual > A calculated > B, the air heat source pump heating mode is switched to the air heat source pump and municipal steam dual heat source heating mode.

[0090] Case 3: When Acalculated < B, and Aactual < Acalculated < B or Acalculated < Aactual < B, maintain the municipal steam heating mode.

[0091] Case 4: When Acalculated < B, and Acalculated < B < Aactual, after the system operation and indoor temperature remain stable, if Tactual > Ttarget, the air heat source pump heating mode continues to operate.

[0092] Case 5: When A calculated < B, and A calculated < B < A actual, the air heat source pump heating mode is enabled. When the system operation and indoor temperature remain stable, if T actual < T target, the air heat source pump heating mode is switched to the air heat source pump and municipal steam dual heat source heating mode.

Point cloud filtering, also known as point cloud filtering, is one of the basic steps in point cloud processing. It is usually performed before advanced three-dimensional image processing. The main purpose of point cloud filtering is to remove noise, improve the quality of point clouds, and simplify point cloud data for subsequent processing. In this application, the IPC module is used to perform intelligent filtering of point clouds, select point cloud clusters about data, and then perform data analysis on the point cloud clusters; point cloud recognition, also known as point cloud target detection, aims to accurately detect and identify different objects from point clouds. Its principle can be divided into four steps: data preprocessing, feature extraction, target detection and recognition. In the data preprocessing stage, operations such as denoising, filtering and coordinate transformation are required to improve the quality of point clouds and adapt them to subsequent processing. In the feature extraction stage, meaningful features such as shape features, color features and normal features are extracted from point cloud data. Then, in the target detection stage, the extracted features are used to detect the target objects in the point cloud. Finally, in the target recognition stage, the detected target objects are identified and classified. Methods based on features such as the shape, texture, and color of the object can be used, or end-to-end recognition can be performed using a deep learning model. Therefore, in this application, the point cloud is processed through the above four steps of preprocessing, extraction, detection, and recognition of the point cloud. In the actual working process, the IPC module can be used to visually identify and collect the continuous irradiation of the steam flow meter, outdoor weather station, temperature sensor, air heat source pump heat metering, air heat source pump electricity metering, steam pipeline regulating valve, and air heat source pump. If any value changes, the IPC module will collect and record it in time, further liberating the monitoring work of personnel and realizing the automation of monitoring work.

The calculation formula for Q is Q=L max *2.51*277.8; Step A6: Collect the equipment heating performance coefficient according to the air heat source pump manufacturer's manual and mark it as COP 样本 ; Step A7: Configure the load Q and equipment heating performance coefficient COP according to the air heat source pump 样本 Determine the number of air heat source pumps; Step B: The intelligent control module calculates the optimal cost selection scheme based on the control quantity of the air heat source pump and determines the selection of the air heat source and / or municipal thermal steam heat source mode. Step B includes the following sub-steps: Step B1: Collect physical data of each module through the intelligent control module and calculate the unit GJ heat of the air heat source pump and the unit GJ heat of the municipal steam; Step B2: Calculate the cost per GJ of heat from the air heat source pump and express it as A; Step B3: Calculate the municipal steam unit GJ heat and express it as B; Step B4: Calculate and compare the usage costs of A and B; Step B5: Compare the relationship between A and B and the cost of use and select the air heat source and / or municipal thermal steam heat source mode. The operation mode is: Theoretically, the cost per GJ of heat required by the air heat source pump is A 计算 It is automatically calculated by the intelligent control module, and the calculation formula is the theoretical amount of electricity required for the air heat pump to heat 1GJ of heat multiplied by the corresponding electricity price; In fact, the cost of air heat source pump per GJ of heat is A 实际 It is automatically calculated by the intelligent control module, and the calculation formula is the power required by the air heat pump to heat 1GJ of heat multiplied by the corresponding electricity price; The cost of municipal steam per GJ of heat is represented by B, which is automatically calculated by the intelligent control module. The calculation formula is the steam price divided by 2.51; Under the outdoor ambient temperature Toutdoor, compare the costs of A and B, and then select the corresponding heating mode according to the cost, specifically: Case 1: When A calculated > B, the air heat source pump heating mode is enabled. After the system runs and the indoor temperature remains stable, if T actual > T target, and A actual > A calculated > B, the air heat source pump heating mode continues to run and ensures continuous and stable heating. Case 2: When A calculated > B, the air heat source pump heating mode is enabled. When the system is running and the indoor temperature remains stable, if T actual < T target, and A actual > A calculated > B, the air heat source pump heating mode is switched to the air heat source pump and municipal steam dual heat source heating mode; Case 3: When A calculated < B, and A actual < A calculated < B or A calculated < A actual < B, maintain the municipal steam heating mode; Case 4: When A calculated < B, and A calculated < B < A actual, after the system operation and indoor temperature remain stable, if T actual > T target, the air heat source pump heating mode continues to operate; Case 5: When A calculated < B, and A calculated < B < A actual, the air heat source pump heating mode is enabled. When the system operation and indoor temperature remain stable, if T actual < T target, the air heat source pump heating mode is switched to the air heat source pump and municipal steam dual heat source heating mode.
