Description

Technical Field

[0001] The utility model relates to the technical field of temperature control, in particular to a heating temperature control device and equipment. Background Art

[0002] The heating problem in northern winter is closely related to people's lives. The heating area in the north is wide, and the reasonable control of the heating temperature is not only related to whether residents can be given a warm indoor environment, but also directly related to energy and environmental issues.

[0003] At present, the water supply temperature of the heating system in each community is constant. At the beginning, end and cold season of heating, the hot water regulating valve needs to be manually adjusted to control the water supply temperature. In other time periods, no matter how the outdoor ambient temperature changes, the same water supply temperature is used for heating. This will cause the indoor temperature to be too high when the outdoor ambient temperature is high during the day, and the indoor temperature to be too low when the outdoor ambient temperature is low at night. The problem of uneven indoor temperature will occur because the heating temperature cannot adapt to the changes in the outdoor temperature. This will not only affect the comfort of residents, but also greatly reduce the utilization rate of energy. Utility Model Content

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The utility model provides a heating temperature control device, referring to Figure 1 As shown, the heating temperature control device 100 comprises at least: a main temperature control module 110 and at least one subsidiary temperature control module 120;

[0037] The main temperature control module 110 is in communication connection with at least one auxiliary temperature control module 120; the control ends of the main temperature control module 110 and at least one auxiliary temperature control module 120 are respectively connected to the control ends of the hot water regulating valves of different heating pipelines; wherein the heating pipelines are distributed in different indoor areas;

[0038] The temperature acquisition modules of the main temperature control module 110 and at least one auxiliary temperature control module 120 are arranged at different positions in the outdoor environment;

[0039] The main temperature control module 110 is used to collect the outdoor temperature and receive the outdoor temperature sent by at least one auxiliary temperature control module 120, and determine the outdoor average temperature based on each outdoor temperature, so that the main temperature control module 110 and at least one auxiliary temperature control module 120 adjust the opening of the hot water regulating valve according to the outdoor average temperature and the water supply temperature of the corresponding heating pipeline.

[0040] exist Figure 1In the heating temperature control device 100 shown, the temperature acquisition modules of the main temperature control module 110 and at least one auxiliary temperature control module 120 can be evenly distributed in different positions in the external environment. Taking the heating temperature control device 100 as an example of heating temperature control for different buildings in a region, the temperature acquisition modules of the main temperature control module 110 and at least one auxiliary temperature control module 120 can be evenly distributed in the outdoor environment, and the temperature acquisition modules of the main temperature control module 110 and at least one auxiliary temperature control module 120 can also correspond to the external settings of different buildings. The temperature acquisition modules of the main temperature control module 110 and at least one auxiliary temperature control module 120 are used to collect outdoor temperature. Based on the communication connection between the main temperature control module 110 and at least one auxiliary temperature control module 120, the auxiliary temperature control module 120 transmits the collected outdoor temperature to the main temperature control module 110. The main temperature control module 110 calculates the outdoor average temperature based on the collected indoor temperature and the received indoor temperature, and then transmits the calculated outdoor average temperature to at least one auxiliary temperature control module 120. The hot water regulating valve is located on the primary side of the heating end. The control end of the main temperature control module 110 can be connected to the control end of the hot water regulating valve of the corresponding heating pipeline. The main temperature control module 110 compares the outdoor average temperature with the preset temperature upper limit and temperature lower limit. When the outdoor average temperature is lower than the temperature lower limit, the opening of the connected hot water regulating valve is increased; when the outdoor average temperature is higher than the temperature upper limit, the opening of the connected hot water regulating valve is reduced; similarly, the control end of the auxiliary temperature control module 120 can be connected to the control end of the hot water regulating valve of the corresponding heating pipeline. After receiving the outdoor average temperature transmitted by the main temperature control module 110, the auxiliary temperature control module 120 compares the outdoor average temperature with the preset temperature upper limit and temperature lower limit. When the outdoor average temperature is lower than the temperature lower limit, the opening of the connected hot water regulating valve is increased; when the outdoor average temperature is higher than the temperature upper limit, the opening of the connected hot water regulating valve is reduced.

[0041] In this way, the outdoor average temperature is determined by collecting various outdoor temperatures, so that the main temperature control module and at least one auxiliary temperature control module adjust the opening of the hot water regulating valve in the heating pipeline according to the outdoor average temperature, thereby realizing the adjustment of the water supply temperature according to the outdoor average temperature, so that the water supply temperature adapts to the change of the outdoor temperature, and ensures the balance of the indoor heating temperature under any outdoor ambient temperature. In addition, the main temperature control module and at least one auxiliary temperature control module both adjust the opening of the hot water regulating valve based on the outdoor average temperature, avoiding the problem of excessively high local heating temperature and ensuring the uniformity of the heating temperature in the region. The heating temperature is controlled according to the change of the outdoor average temperature, and there is no need to manually adjust the valve to control the heating water temperature. No matter how the outdoor temperature changes, the indoor heating temperature can be guaranteed, which can reduce manual operations, save labor costs, and reduce energy waste.

[0042] In specific implementation, in the heating temperature control device 100 provided in the embodiment of the present application, the main temperature control module 110 has a variety of structures to realize its functions, such as Figure 2 As shown, the main temperature control module 110 at least includes: a first control module 111, a first communication module 112 and a first temperature acquisition module 113;

[0043] A first end of the first control module 111 is connected to the first temperature acquisition module 113, and a second end of the first control module 111 is connected to a first end of the first communication module 112;

[0044] A second end of the first communication module 112 is connected to at least one subsidiary temperature control module 120 .

[0045] exist Figure 2 In the heating temperature control device 100 shown, the first temperature acquisition module 113 is arranged at a corresponding light-proof and ventilated position in the outdoor environment, and the first temperature acquisition module 113 is used to collect the outdoor temperature at the location. The first communication module 112 is used to realize data interaction between the main temperature control module 110 and the auxiliary temperature control module 120. The first control module 111 may include a master station PLC, and the master station PLC uses an S7-1500 series module. The first control module 111 is used to receive the outdoor temperature collected by each auxiliary temperature control module 120 through the first communication module 112, filter the outdoor temperature collected by the first temperature acquisition module 113 and the outdoor temperature collected by each auxiliary temperature control module 120, obtain the filtered outdoor temperatures, calculate the average value of the filtered outdoor temperatures, use the average value as the outdoor average temperature, and send the outdoor average temperature to each auxiliary temperature control module 120 through the first communication module 112. Among them, the filtering process is to filter out the outdoor temperature outside the preset temperature range to reduce the error interference caused by environmental factors such as snow cover and strong sunlight. The first control module 111 is also used to compare the outdoor average temperature with the preset temperature upper limit and temperature lower limit. When the outdoor average temperature is lower than the temperature lower limit, the opening of the hot water regulating valve is increased; when the outdoor average temperature is higher than the temperature upper limit, the opening of the hot water regulating valve is reduced. When other comparison results are obtained, the valve opening is not adjusted.

[0046] In specific implementation, in the heating temperature control device 100 provided in the embodiment of the present application, the auxiliary temperature control module 120 has a variety of structures to realize its functions, such as Figure 2 As shown, the auxiliary temperature control module 120 at least includes: a second control module 121, a second communication module 122 and a second temperature acquisition module 123;

[0047] A first end of the second control module 121 is connected to the second temperature acquisition module 123 , and a second end of the second control module 121 is connected to a first end of the second communication module 122 ;

[0048] The second end of the second communication module 122 is connected to the second end of the first communication module.

[0049] exist Figure 2 In the heating temperature control device 100 shown, the second temperature acquisition module 123 is set at a corresponding light-proof and ventilated position in the outdoor environment, and is different from the setting position of the first temperature acquisition module 113. The second temperature acquisition module 123 is used to collect the outdoor temperature at the location. The second communication module 122 is used to realize the data interaction between the auxiliary temperature control module 120 and the main temperature control module 110. The second control module 121 may include a substation PLC. The second control module 121 is used to send the outdoor temperature collected by the second temperature acquisition module 123 to the main temperature control module 110 through the second communication module 122, and receive the outdoor average temperature transmitted by the main temperature control module 110 through the second communication module 122. The second control module 121 is also used to compare the outdoor average temperature with the preset temperature upper limit and temperature lower limit. When the outdoor average temperature is lower than the temperature lower limit, the opening of the hot water regulating valve is increased; when the outdoor average temperature is higher than the temperature upper limit, the opening of the hot water regulating valve is reduced. When other comparison results are obtained, the valve opening is not adjusted.

[0050] In a possible implementation, the first temperature acquisition module includes at least one temperature sensor, and the second temperature acquisition module includes at least one temperature sensor, and the temperature sensors are arranged in a light-proof and ventilated position in an outdoor environment through a fixed bracket.

[0051] In practical applications, the temperature sensors in the first temperature acquisition module and the second temperature acquisition module can be PT100, whose range is 0-100°C, and the output signal can be converted into a two-wire 4-20mA current signal. Both the first temperature acquisition module and the second acquisition module can include at least one temperature sensor. When the first temperature acquisition module includes one temperature sensor, the temperature collected by the sensor is the outdoor temperature collected by the first temperature acquisition module; when the first temperature acquisition module includes multiple temperature sensors, the temperature collected by one of the temperature sensors can be used as the outdoor temperature collected by the first temperature acquisition module, or the average value of the temperatures collected by each temperature sensor can be used as the outdoor temperature collected by the first temperature acquisition module through the first control module. Similarly, when the second temperature acquisition module includes one temperature sensor, the temperature collected by the sensor is the outdoor temperature collected by the second temperature acquisition module; when the second temperature acquisition module includes multiple temperature sensors, the temperature collected by one of the temperature sensors can be used as the outdoor temperature collected by the second temperature acquisition module, and the average value of the temperatures collected by each temperature sensor can be used as the outdoor temperature collected by the second temperature acquisition module through the second control module. In this way, by respectively arranging a plurality of temperature sensors in the first temperature acquisition module and the second temperature acquisition module, it is possible to avoid the situation where the outdoor temperature cannot be collected due to damage of the temperature sensor, thereby improving the reliability of the heating temperature control device.

[0052] In a possible implementation, the first communication module and the second communication module are Internet of Things communication modules, and the first communication module and the second communication module exchange data through a communication base station. The communication base station is used to provide communication services for the Internet of Things communication module to realize data exchange between the first communication module and the second communication module.

[0053] In the embodiment of the present application, when the outdoor average temperature is lower than the preset lower temperature limit, the opening of the hot water regulating valve is increased; when the outdoor average temperature is higher than the preset upper temperature limit, the opening of the hot water regulating valve is reduced; when other comparison results are obtained, the valve opening is not adjusted. This not only saves energy, but also closely integrates the primary side of the heating end with the PLC and the Internet of Things communication module, thereby realizing dynamic intelligent heating control, improving heating effects, increasing energy utilization, and reducing heating costs.

[0054] In a possible implementation, the first end of the first control module is connected to the first temperature acquisition module through a flame-retardant shielded flexible cable, and the second end of the first control module is connected to the first end of the first communication module through a network cable; the first end of the second control module is connected to the second temperature acquisition module through a flame-retardant shielded flexible cable, and the second end of the second control module is connected to the first end of the second communication module through a network cable. The flame-retardant shielded flexible cable is a computer flame-retardant shielded flexible cable of model ZR-DJYPVPR.

[0056] The temperature monitoring module 130 is electrically connected to the main temperature control module 110 and at least one subsidiary temperature control module 120 .

[0057] exist Figure 3 In the heating temperature control device 100 shown, the temperature monitoring module 130 is connected to the main temperature control module 110 and the at least one auxiliary temperature control module 120 via a network cable. The temperature monitoring module 130 of the temperature monitoring platform is used to receive the outdoor temperature sent by the main temperature control module 110 and the at least one auxiliary temperature control module 120, and monitor the outdoor temperature. When the outdoor temperature exceeds a preset range, an early warning operation is performed. In addition, the temperature monitoring module is connected to an external temperature monitoring platform via a network cable, and information such as the outdoor temperature, the execution time of the early warning operation, and the number of early warnings are sent to the external temperature monitoring platform.

[0058] In one possible implementation, see Figure 4 As shown, the heating temperature control device 100 may further include: an early warning module 140;

[0059] The early warning module 140 is electrically connected to the main temperature control module 110 , at least one subsidiary temperature control module 120 , and the temperature monitoring module 130 , respectively.

[0060] exist Figure 4In the heating temperature control device 100 shown, the early warning module is used to warn in the form of sound and / or light under the control of the temperature monitoring module 130. The early warning module 140 includes a first early warning submodule and a plurality of second early warning submodules. The first early warning submodule is connected to the temperature monitoring module 130, and the first early warning submodule is arranged near the temperature monitoring module 130.
