BRIEF DESCRIPTION OF THE DRAWINGS

[0067] Figure 1 A flow chart of a secondary side heat supply adaptive regulation method according to the present invention is shown;

[0068] Figure 2 A block diagram of a secondary side heat supply adaptive regulation system of the present invention is shown. DETAILED DESCRIPTION

[0069] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0070] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0071] Figure 1 A flow chart of a secondary side heat supply adaptive regulation method of the present invention is shown.

[0072] like Figure 1 As shown, the present invention discloses a secondary side heat supply adaptive regulation method, comprising:

[0073] S102, obtaining the heating temperature value of the farthest end of the secondary side pipe network;

[0074] S104, comparing and analyzing the heating temperature value at the farthest end of the secondary side pipe network with the preset target temperature value to obtain a heating temperature difference;

[0075] S106, determining whether the heating temperature difference is within a preset temperature difference range, and if not, obtaining a distance value from the farthest end of the secondary side pipe network to the heating point;

[0076] S108, obtaining a temperature adjustment level corresponding to the secondary side heating according to the heating temperature difference and the distance from the farthest end of the secondary side pipe network to the hot spot;

[0077] S110, regulating the heat supply of the secondary side pipe network according to the temperature adjustment level of the secondary side heat supply.

[0078] It should be noted that the closer the secondary pipe network is to the heating station, the higher its temperature. When the heating temperature value at the farthest end of the secondary pipe network meets the standard, the heating port temperature of the entire secondary pipe network will reach the predetermined standard. Subtract the preset target temperature value from the heating temperature value at the farthest end of the secondary pipe network to obtain the heating temperature difference. If the preset temperature difference range is Celsius, when the heating temperature difference is within the corresponding preset temperature difference range, the heating temperature value at the farthest end of the secondary side heating network is normal; if the heating temperature difference is less than the preset temperature difference range, it may cause insufficient heating and the temperature adjustment level of the secondary side heating needs to be increased; if the heating temperature difference is greater than the preset temperature range, it means that the corresponding secondary side network heating is sufficient and there is waste, and the temperature adjustment level of the secondary side heating needs to be lowered; the higher the temperature adjustment level, the higher the corresponding secondary side network heating temperature value.

[0079] According to an embodiment of the present invention, the further embodiment includes:

[0080] Obtain the thermal reflux cycle at the farthest end of the secondary side pipe network;

[0081] Determine whether the heat reflux period at the farthest end of the secondary side pipe network is less than a preset time period, and if so, increase the temperature adjustment level of the primary secondary side heating;

[0082] The temperature adjustment level information for increasing the primary secondary side heating is sent to the preset management terminal and displayed.

[0083] It should be noted that when the secondary side pipe network heating port is not used by users, the secondary side heating pipe network does not need to continue to supply heat. When the heating temperature value of the secondary side pipe network heating port drops to the preset temperature threshold, the thermal reflux of the secondary side pipe network will be triggered to increase the temperature value of the heating in the secondary side pipe network. For example, if the preset time period is 10 minutes, when the thermal reflux cycle at the farthest end of the secondary side pipe network is less than 10 minutes, the temperature adjustment level of the secondary side heating is increased to achieve the effect of increasing the thermal reflux cycle. The preset time period varies according to different heating time points.

[0084] According to an embodiment of the present invention, the step of obtaining the thermal recirculation period at the farthest end of the secondary side pipe network specifically includes:

[0085] Determine whether the heating temperature value at the farthest end of the secondary side pipe network is lower than a preset temperature threshold. If so, start the thermal reflux system for secondary side heating to increase the heating temperature in the secondary side pipe network, and record the time when the corresponding system is started, which is recorded as the first time;

[0086] Obtain the time when the thermal reflux system for secondary side heating was last started, and record it as the second time;

[0087] According to the first time and the second time, the thermal reflux period at the farthest end of the secondary side pipe network is obtained.

[0088] It should be noted that the thermal reflux period of the farthest end of the secondary side pipe network is equal to the first time minus the second time. When the heating supply at the farthest end of the secondary side pipe network is guaranteed, the heating supply ports of other secondary side pipe networks will also be guaranteed.

[0089] According to an embodiment of the present invention, the step of obtaining the preset temperature threshold specifically includes:

[0090] Get the ambient temperature value at the farthest end of the secondary side pipe network;

[0091] Based on the preset ambient temperature range within which the ambient temperature value at the farthest end of the secondary pipe network falls, determining an influence coefficient of the ambient temperature at the farthest end of the secondary pipe network on the preset temperature threshold, and setting the influence coefficient as a first influence coefficient;

[0092] Obtain the historical heat usage value of the user at the farthest end of the secondary side pipe network;

[0093] Based on the preset heat usage value range within which the historical heat usage value of the user at the farthest end of the secondary side pipe network falls, determining the influence coefficient of the heat usage value of the user at the farthest end of the secondary side pipe network on the preset temperature threshold, and setting it as the second influence coefficient;

[0094] A preset temperature threshold is obtained according to the first influence coefficient, the second influence coefficient and the preset minimum heating temperature.

[0095] It should be noted that each preset ambient temperature range corresponds to a first influence coefficient, set as a. For example, the ambient temperature value at the farthest end of the secondary side pipe network falls into the preset ambient temperature range of , then the corresponding first influence coefficient is ; Each preset range of heat usage value corresponds to a second influence coefficient, and the influence coefficient of the heat usage value of the user at the farthest end of the secondary side pipe network on the preset temperature threshold will be set to ; If the default minimum heating temperature is set to , then the corresponding preset temperature threshold The influence coefficient of the ambient temperature at the farthest end of the secondary side pipe network on the preset temperature threshold, the influence coefficient of the user's heat value at the farthest end of the secondary side pipe network on the preset temperature threshold, and the preset minimum heating temperature are all set by technical personnel in this field according to actual needs.

[0096] According to an embodiment of the present invention, the step of obtaining the preset time period specifically includes:

[0097] Obtain the total heat usage information of the user at the farthest end of the secondary side pipe network;

[0098] Dividing the total heat value of the historical user at the farthest end of the secondary side pipe network according to time, to obtain the heat value of the historical user at the farthest end of the secondary side pipe network at different time points;

[0099] Compare and analyze the historical heat usage values ​​of the farthest end user of the secondary pipe network at different time points and the total heat usage values ​​of the farthest end user of the secondary pipe network at different time points to obtain the historical heat usage ratio of the farthest end user of the secondary pipe network at different time points;

[0100] The length of the corresponding preset time period is matched according to the historical heat usage ratio of the user at the farthest end of the secondary side pipe network at different time points.

[0101] It should be noted that the total heat usage value of the farthest end of the secondary pipe network is divided according to time, and the heat usage value of the farthest end of the secondary pipe network at different time points is obtained. The length of the preset time period is set as , set the time period at different time points to , whose formula is ,in Indicates the corresponding time point The historical heat value of the user at the farthest end of the secondary side pipe network, Indicates the total heat consumption of the farthest end user in the secondary pipe network. Indicates the preset initial time period, and sets the minimum time period of the time period at different time points in the heat return cycle at the farthest end of the secondary side pipe network as the preset time period, that is, the preset time period is .

[0102] According to an embodiment of the present invention, the step of obtaining the temperature adjustment level corresponding to the secondary side heating according to the heating temperature difference and the distance from the farthest end of the secondary side pipe network to the hot spot specifically includes:

[0103] According to the temperature difference range that the heating temperature difference falls into, the influence coefficient of the corresponding heating temperature difference on the temperature adjustment level of the secondary side heating is matched and set as the third influence coefficient;

[0104] According to the distance range within which the distance value from the farthest end of the secondary side pipe network to the hot spot falls, the influence coefficient of the distance value from the farthest end of the secondary side pipe network to the hot spot on the temperature adjustment level of the secondary side heating is matched, and set as the fourth influence coefficient;

[0105] According to the heating temperature value of the farthest end of the secondary side pipe network, the temperature level number corresponding to the heating temperature value of the farthest end of the secondary side pipe network is obtained;

[0106] The temperature regulation level corresponding to the secondary side heating is obtained according to the third influence coefficient, the fourth influence coefficient and the temperature level number corresponding to the heating temperature value at the farthest end of the secondary side pipe network.

[0107] It should be noted that the heating temperature value at the farthest end of the secondary pipe network is divided into levels according to the preset temperature range. For example, with 50 degrees Celsius as the benchmark, each increase of 5 degrees Celsius is divided into one level. If the heating temperature value at the farthest end of the secondary pipe network is 57 degrees Celsius, the temperature level number corresponding to the heating temperature value is 2. The actual heating temperature level at the farthest end of the secondary pipe network is the product of the third influence coefficient, the fourth influence coefficient and the temperature level number corresponding to the heating temperature value at the farthest end of the secondary pipe network. The temperature adjustment level number of the secondary heating is equal to the actual heating temperature level at the farthest end of the secondary pipe network minus the temperature level number corresponding to the heating temperature value at the farthest end of the secondary pipe network, and only rounding up is performed. For example, the temperature adjustment level number of the secondary heating is , then the temperature adjustment level is 3. The third influence coefficient, the fourth influence coefficient and the temperature level corresponding to the heating temperature value at the farthest end of the secondary side pipe network are all set by those skilled in the art according to actual needs.

[0108] According to an embodiment of the present invention, the further embodiment includes:

[0109] Obtain the flow value consumed per unit time by the secondary side pipe network heating port and the corresponding heating temperature value;

[0110] According to the flow value consumed by the secondary side pipe network heating port in unit time and the corresponding heating temperature value, the heat used by the corresponding secondary side pipe network heating port in unit time is obtained;

[0111] Determine whether the heat used by the secondary side pipe network heating port in unit time exceeds the heat threshold consumed by the corresponding secondary side pipe network heating port in unit time, and if so, trigger a prompt message;

[0112] Send the reminder information to the preset management terminal for reminder.

[0113] It should be noted that the heat threshold consumed per unit time by the secondary side pipe network heating port is proportional to the heating area of ​​the corresponding secondary side pipe network heating port. If the heat consumed per square area per unit time is set to , the heating area corresponding to the secondary side pipe network heating port is set to , then the heat threshold consumed per unit time by the corresponding secondary side pipe network heating port is set to ,in It represents the floating coefficient. When the heat used by the secondary side pipe network heating port in unit time exceeds the heat threshold consumed by the corresponding secondary side pipe network heating port in unit time, it indicates that the corresponding secondary side pipe network heating port has an abnormal heating situation. A corresponding prompt message will be generated for the corresponding abnormal heating situation and sent to the preset management terminal.

[0114] According to an embodiment of the present invention, the further embodiment includes:

[0115] Get the actual flow value of the secondary side pipe network heating port;

[0116] Compare and analyze the actual flow value of the secondary side pipe network heating port with the preset flow value to obtain the heating efficiency of the secondary side pipe network heating port;

[0117] Determine whether the heating efficiency of the secondary side pipe network heating port is less than a preset efficiency threshold. If so, trigger a prompt message.

[0118] It should be noted that the heating efficiency of the secondary side heating pipe network heating port is the ratio of the actual flow value of the corresponding secondary side heating pipe network heating port to the preset flow value. If the heating efficiency of the secondary side heating pipe network heating port is less than the preset efficiency threshold, it means that the heating of the corresponding secondary side heating pipe network heating port cannot meet people's needs, and thus triggers a prompt message, and sends the prompt message to the preset management end for corresponding maintenance processing, etc. The preset efficiency threshold is set by technical personnel in this field according to actual needs.

[0119] According to an embodiment of the present invention, the further embodiment includes:

[0120] Get the pressure value of the secondary side pipe network heating port;

[0121] Determine whether the pressure value of the secondary side pipe network heating port is within the preset pressure range, if so, it is displayed as normal; otherwise, it is abnormal;

[0122] The abnormal pressure value of the secondary side pipe network heating port is sent to the preset control management terminal for prompting.

[0123] It should be noted that the pressure value of the secondary side pipe network heating port is detected by a preset pressure sensor. If the pressure value of the secondary side pipe network heating port is within the preset pressure range, the corresponding pressure value of the secondary side pipe network heating port is normal, otherwise it is abnormal, and the abnormal pressure value is sent to the preset management end for display. The pressure value of the secondary side pipe network heating port is adjusted through the preset management end. The preset pressure range is set by technical personnel in this field according to actual needs.

[0124] Figure 2 A block diagram of a secondary side heat supply adaptive regulation system of the present invention is shown.

[0125] like Figure 2 As shown, the second aspect of the present invention provides a secondary side heat supply adaptive regulation system 2, including a memory 21 and a processor 22. The memory stores a secondary side heat supply adaptive regulation method program. When the secondary side heat supply adaptive regulation method program is executed by the processor, the following steps are implemented:

[0126] Obtain the heating temperature value at the farthest end of the secondary side pipe network;

[0127] Compare and analyze the heating temperature value at the farthest end of the secondary side pipe network with the preset target temperature value to obtain the heating temperature difference;

[0128] Determine whether the heating temperature difference is within a preset temperature difference range; if not, obtain the distance from the farthest end of the secondary side pipe network to the heating point;

[0129] According to the heating temperature difference and the distance from the farthest end of the secondary side pipe network to the hot spot, the temperature adjustment level corresponding to the secondary side heating is obtained;

[0130] The heat supply of the secondary side pipe network is adjusted according to the temperature adjustment level of the secondary side heat supply.

[0131] It should be noted that the closer the secondary pipe network is to the heating station, the higher its temperature. When the heating temperature value at the farthest end of the secondary pipe network meets the standard, the heating port temperature of the entire secondary pipe network will reach the predetermined standard. Subtract the preset target temperature value from the heating temperature value at the farthest end of the secondary pipe network to obtain the heating temperature difference. If the preset temperature difference range is Celsius, when the heating temperature difference is within the corresponding preset temperature difference range, the heating temperature value at the farthest end of the secondary side heating network is normal; if the heating temperature difference is less than the preset temperature difference range, it may cause insufficient heating and the temperature adjustment level of the secondary side heating needs to be increased; if the heating temperature difference is greater than the preset temperature range, it means that the corresponding secondary side network heating is sufficient and there is waste, and the temperature adjustment level of the secondary side heating needs to be lowered; the higher the temperature adjustment level, the higher the corresponding secondary side network heating temperature value.

[0132] According to an embodiment of the present invention, the further embodiment includes:

[0133] Obtain the thermal reflux cycle at the farthest end of the secondary side pipe network;

[0134] Determine whether the heat reflux period at the farthest end of the secondary side pipe network is less than a preset time period, and if so, increase the temperature adjustment level of the primary secondary side heating;

[0135] The temperature adjustment level information for increasing the primary secondary side heating is sent to the preset management terminal and displayed.

[0136] It should be noted that when the secondary side pipe network heating port is not used by users, the secondary side heating pipe network does not need to continue to supply heat. When the heating temperature value of the secondary side pipe network heating port drops to the preset temperature threshold, the thermal reflux of the secondary side pipe network will be triggered to increase the temperature value of the heating in the secondary side pipe network. For example, if the preset time period is 10 minutes, when the thermal reflux cycle at the farthest end of the secondary side pipe network is less than 10 minutes, the temperature adjustment level of the secondary side heating is increased to achieve the effect of increasing the thermal reflux cycle. The preset time period varies according to different heating time points.

[0137] According to an embodiment of the present invention, the step of obtaining the thermal recirculation period at the farthest end of the secondary side pipe network specifically includes:

[0138] Determine whether the heating temperature value at the farthest end of the secondary side pipe network is lower than a preset temperature threshold. If so, start the thermal reflux system for secondary side heating to increase the heating temperature in the secondary side pipe network, and record the time when the corresponding system is started, which is recorded as the first time;

[0139] Obtain the time when the thermal reflux system for secondary side heating was last started, and record it as the second time;

[0140] According to the first time and the second time, the thermal reflux period at the farthest end of the secondary side pipe network is obtained.

[0141] It should be noted that the thermal reflux period of the farthest end of the secondary side pipe network is equal to the first time minus the second time. When the heating supply at the farthest end of the secondary side pipe network is guaranteed, the heating supply ports of other secondary side pipe networks will also be guaranteed.

[0142] According to an embodiment of the present invention, the step of obtaining the preset temperature threshold specifically includes:

[0143] Get the ambient temperature value at the farthest end of the secondary side pipe network;

[0144] Based on the preset ambient temperature range within which the ambient temperature value at the farthest end of the secondary pipe network falls, determining an influence coefficient of the ambient temperature at the farthest end of the secondary pipe network on the preset temperature threshold, and setting the influence coefficient as a first influence coefficient;

[0145] Obtain the historical heat usage value of the user at the farthest end of the secondary side pipe network;

[0146] Based on the preset heat usage value range within which the historical heat usage value of the user at the farthest end of the secondary side pipe network falls, determining the influence coefficient of the heat usage value of the user at the farthest end of the secondary side pipe network on the preset temperature threshold, and setting it as the second influence coefficient;

[0147] A preset temperature threshold is obtained according to the first influence coefficient, the second influence coefficient and the preset minimum heating temperature.

[0148] It should be noted that each preset ambient temperature range corresponds to a first influence coefficient, set as a. For example, the ambient temperature value at the farthest end of the secondary side pipe network falls into the preset ambient temperature range of , then the corresponding first influence coefficient is ; Each preset range of heat usage value corresponds to a second influence coefficient, and the influence coefficient of the heat usage value of the user at the farthest end of the secondary side pipe network on the preset temperature threshold will be set to ; If the default minimum heating temperature is set to , then the corresponding preset temperature threshold The influence coefficient of the ambient temperature at the farthest end of the secondary side pipe network on the preset temperature threshold, the influence coefficient of the user's heat value at the farthest end of the secondary side pipe network on the preset temperature threshold, and the preset minimum heating temperature are all set by technical personnel in this field according to actual needs.

[0149] According to an embodiment of the present invention, the step of obtaining the preset time period specifically includes:

[0150] Obtain the total heat usage information of the user at the farthest end of the secondary side pipe network;

[0151] Dividing the total heat value of the historical user at the farthest end of the secondary side pipe network according to time, to obtain the heat value of the historical user at the farthest end of the secondary side pipe network at different time points;

[0152] Compare and analyze the historical heat usage values ​​of the farthest end user of the secondary pipe network at different time points and the total heat usage values ​​of the farthest end user of the secondary pipe network at different time points to obtain the historical heat usage ratio of the farthest end user of the secondary pipe network at different time points;

[0153] The length of the corresponding preset time period is matched according to the historical heat usage ratio of the user at the farthest end of the secondary side pipe network at different time points.

[0154] It should be noted that the total heat usage value of the farthest end of the secondary pipe network is divided according to time, and the heat usage value of the farthest end of the secondary pipe network at different time points is obtained. The length of the preset time period is set as , set the time period at different time points to , whose formula is ,in Indicates the corresponding time point The historical heat value of the user at the farthest end of the secondary side pipe network, Indicates the total heat consumption of the farthest end user in the secondary pipe network. Indicates the preset initial time period, and sets the minimum time period of the time period at different time points in the heat return cycle at the farthest end of the secondary side pipe network as the preset time period, that is, the preset time period is .

[0155] According to an embodiment of the present invention, the step of obtaining the temperature adjustment level corresponding to the secondary side heating according to the heating temperature difference and the distance from the farthest end of the secondary side pipe network to the hot spot specifically includes:

[0156] According to the temperature difference range that the heating temperature difference falls into, the influence coefficient of the corresponding heating temperature difference on the temperature adjustment level of the secondary side heating is matched and set as the third influence coefficient;

[0157] According to the distance range within which the distance value from the farthest end of the secondary side pipe network to the hot spot falls, the influence coefficient of the distance value from the farthest end of the secondary side pipe network to the hot spot on the temperature adjustment level of the secondary side heating is matched, and set as the fourth influence coefficient;

[0158] According to the heating temperature value of the farthest end of the secondary side pipe network, the temperature level number corresponding to the heating temperature value of the farthest end of the secondary side pipe network is obtained;

[0159] The temperature regulation level corresponding to the secondary side heating is obtained according to the third influence coefficient, the fourth influence coefficient and the temperature level number corresponding to the heating temperature value at the farthest end of the secondary side pipe network.

[0160] It should be noted that the heating temperature value at the farthest end of the secondary pipe network is divided into levels according to the preset temperature range. For example, with 50 degrees Celsius as the benchmark, each increase of 5 degrees Celsius is divided into one level. If the heating temperature value at the farthest end of the secondary pipe network is 57 degrees Celsius, the temperature level number corresponding to the heating temperature value is 2. The actual heating temperature level at the farthest end of the secondary pipe network is the product of the third influence coefficient, the fourth influence coefficient and the temperature level number corresponding to the heating temperature value at the farthest end of the secondary pipe network. The temperature adjustment level number of the secondary heating is equal to the actual heating temperature level at the farthest end of the secondary pipe network minus the temperature level number corresponding to the heating temperature value at the farthest end of the secondary pipe network, and only rounding up is performed. For example, the temperature adjustment level number of the secondary heating is , then the temperature adjustment level is 3. The third influence coefficient, the fourth influence coefficient and the temperature level corresponding to the heating temperature value at the farthest end of the secondary side pipe network are all set by those skilled in the art according to actual needs.

[0161] According to an embodiment of the present invention, the further embodiment includes:

[0162] Obtain the flow value consumed per unit time by the secondary side pipe network heating port and the corresponding heating temperature value;

[0164] Determine whether the heat used by the secondary side pipe network heating port in unit time exceeds the heat threshold consumed by the corresponding secondary side pipe network heating port in unit time, and if so, trigger a prompt message;

[0165] Send the reminder information to the preset management terminal for reminder.

[0166] It should be noted that the heat threshold consumed per unit time by the secondary side pipe network heating port is proportional to the heating area of ​​the corresponding secondary side pipe network heating port. If the heat consumed per square area per unit time is set to , the heating area corresponding to the secondary side pipe network heating port is set to , then the heat threshold consumed per unit time by the corresponding secondary side pipe network heating port is set to ,in It represents the floating coefficient. When the heat used by the secondary side pipe network heating port in unit time exceeds the heat threshold consumed by the corresponding secondary side pipe network heating port in unit time, it indicates that the corresponding secondary side pipe network heating port has an abnormal heating situation. A corresponding prompt message will be generated for the corresponding abnormal heating situation and sent to the preset management terminal.

[0168] Get the actual flow value of the secondary side pipe network heating port;

[0170] Determine whether the heating efficiency of the secondary side pipe network heating port is less than a preset efficiency threshold. If so, trigger a prompt message.

[0171] It should be noted that the heating efficiency of the secondary side heating pipe network heating port is the ratio of the actual flow value of the corresponding secondary side heating pipe network heating port to the preset flow value. If the heating efficiency of the secondary side heating pipe network heating port is less than the preset efficiency threshold, it means that the heating of the corresponding secondary side heating pipe network heating port cannot meet people's needs, and thus triggers a prompt message, and sends the prompt message to the preset management end for corresponding maintenance processing, etc. The preset efficiency threshold is set by technical personnel in this field according to actual needs.

[0172] According to an embodiment of the present invention, the further embodiment includes:

[0173] Get the pressure value of the secondary side pipe network heating port;

[0174] Determine whether the pressure value of the secondary side pipe network heating port is within the preset pressure range, if so, it is displayed as normal; otherwise, it is abnormal;

[0175] The abnormal pressure value of the secondary side pipe network heating port is sent to the preset control management terminal for prompting.

[0176] It should be noted that the pressure value of the secondary side pipe network heating port is detected by a preset pressure sensor. If the pressure value of the secondary side pipe network heating port is within the preset pressure range, the corresponding pressure value of the secondary side pipe network heating port is normal, otherwise it is abnormal, and the abnormal pressure value is sent to the preset management end for display. The pressure value of the secondary side pipe network heating port is adjusted through the preset management end. The preset pressure range is set by technical personnel in this field according to actual needs.
