[0001] This invention relates to the field of heating supply equipment technology, and in particular to a heating system and heating control method. Background Technology

[0002] To meet the heating needs of multiple rooms, it is currently common practice to install a heating unit or heating sub-unit in each room, and each heating unit or heating sub-unit is controlled by a separate room thermostat. This results in a large number of heating sub-units in the heating system, which on the one hand makes the installation of the heating system cumbersome and the equipment bulky, and on the other hand, it also leads to poor flexibility in the control and scheduling of the heating system, making it impossible to quickly adjust the temperature of each room.

[0025] Compared with the prior art, the heating control method of the present invention has the following advantages: it uses a room controller to control the heating of all heating areas, simplifies the system structure of the heating system, and improves the flexibility of the heating system control and scheduling; at the same time, the main thermostat serves as a relay station for information transmission and communication between the auxiliary thermostat and the room controller. The main thermostat can filter the information transmitted by the auxiliary thermostat and only send the data required by the room controller, that is, the data related to the heating adjustment request, to the room controller, thereby improving the data processing efficiency and response efficiency of the room controller to the heating adjustment request, enabling the room controller to quickly adjust the temperature of each heating area.

[0026] In one embodiment, the primary and secondary temperature controllers establish a communication connection based on the order in which they enter the pairing state, including:

[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "multiple" means two or more.

[0055] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0056] As described in the background section above, in order to meet the heating needs of multiple rooms, a heating grading device and a corresponding room thermostat are set up for each room in the heating system. This results in cumbersome installation of the heating system, bulky equipment, poor control and scheduling flexibility of the heating system, and inability to quickly adjust the temperature of each room.

[0057] Based on this, the present invention provides a heating system and a heating control method, which uses a room controller to control the heating of all heating areas, simplifying the system structure of the heating system and improving the flexibility of the heating system control and scheduling; at the same time, the main thermostat acts as a relay station for information transmission and communication between the auxiliary thermostat and the room controller. The main thermostat can filter the information transmitted by the auxiliary thermostat and only send the data required by the room controller, that is, the data related to the heating adjustment request, to the room controller, thereby improving the data processing efficiency and response efficiency of the room controller to the heating adjustment request, enabling the room controller to quickly adjust the temperature of each heating area.

[0058] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0059] According to an embodiment of the present invention, a heating system is provided. Figure 1 This is a schematic diagram of the structure of a heating system according to this embodiment, as shown below. Figure 1 As shown, the system includes: a heating device 1, a room controller 2, and a thermostat cluster 3. The heating device 1 is used to supply heat to multiple heating zones; it is equipped with multiple water pumps, each corresponding to one of the heating zones. The room controller 2 is connected to each of the water pumps; it controls the start and stop of the water pumps to control the heating of the corresponding heating zone.

[0060] In this embodiment, the thermostat cluster 3 includes a main thermostat 31 and auxiliary thermostats 32. All auxiliary thermostats 32 are communicatively connected to the main thermostat 31, and the main thermostat 31 is communicatively connected to the room controller 2. Simultaneously, the main thermostat 31 and auxiliary thermostats 32 correspond one-to-one with multiple heating zones, respectively regulating the temperature of their respective zones. The main thermostat 31 is used to receive heating adjustment requests from the auxiliary thermostats 32 and to send heating adjustment requests from the main thermostat 31 and / or auxiliary thermostats 32 to the room controller 2. Therefore, the main thermostat 31 serves as a relay station for communication and information transmission between the auxiliary thermostat 32 and the compartment controller 2. The main thermostat 31 can filter the information transmitted by the auxiliary thermostat 32, select the relevant data required by the compartment controller 2, such as data related to heating adjustment requests, and send only this data to the compartment controller 2. This reduces the amount of data received by the compartment controller 2, allowing it to directly control the start and stop of the water pump based on the received data. This improves the data processing efficiency and response efficiency of the compartment controller 2 to heating adjustment requests, enabling it to quickly adjust the temperature of each heating zone.

[0061] In one embodiment, the heating device 1 includes a heating module and heating pipes, with multiple water pumps respectively installed on the heating pipes; optionally, the heating module can be a wall-mounted boiler. The heating pipes are connected to the heating module and also to each heating zone, thereby delivering the heating from the heating module to each heating zone. The water pumps are used to control the heating from the heating module to the corresponding heating zone; when the water pump is turned on, the heating device is connected to the heating pipe connected to the heating zone corresponding to the water pump, and the heating device can provide heating to that heating zone; when the water pump is turned off, the heating pipe is disconnected from the heating pipe connected to the heating zone corresponding to the water pump, and the heating device cannot provide heating to that heating zone. Thus, by controlling the water pumps, the heating from the heating device 1 to each heating zone can be controlled, eliminating the need to install separate heating grading devices in each heating zone, thereby simplifying the structure of the heating system.

[0062] In one embodiment, the water pump can be installed near the heating device and the room controller 2. This eliminates the need to install corresponding water pumps in each heating area, making installation convenient. It also facilitates troubleshooting and maintenance of the heating system.

[0063] In one embodiment, the main temperature controller 31, the auxiliary temperature controller 32, and the compartment controller 2 are all equipped with radio frequency communication units. The main temperature controller 31 and the auxiliary temperature controller 32, as well as the main temperature controller 31 and the compartment controller 2, are all connected via radio frequency communication units, thereby making the main temperature controller 31 a relay station for information transmission and communication between the auxiliary temperature controller 32 and the compartment controller 2. Simultaneously, the main temperature controller 31 is also equipped with a WIFI communication unit, which connects the main temperature controller 31 to the cloud, thereby synchronizing the data of each temperature controller in the temperature control room cluster to the cloud. This avoids the situation where multiple auxiliary temperature controllers 32 might consume excessive router resources when the main temperature controller 31 and the auxiliary temperature controller 32 communicate via WIFI, potentially causing control delays or failures and resulting in poor control performance.

[0064] In one embodiment, the heating device 1 may also be equipped with a WIFI communication unit, through which the heating device 1 communicates with the cloud, thereby synchronizing the working status and related data of the heating device 1 to the cloud.

[0065] In one embodiment, after synchronizing the data of each thermostat and heating device 1, the cloud can display this data to the user in the form of application software, etc. The user can adjust the data of the thermostat and heating device 1 through the application software, such as adjusting the heating temperature of the heating area corresponding to a certain thermostat, turning off the heating of the heating area corresponding to a certain thermostat, etc.

[0066] In one embodiment, Figure 2This is a schematic diagram of the structure of a room controller in a heating system according to this embodiment, as shown below. Figure 2 As shown, the compartment controller 2 includes a control unit 21, an RF communication unit, and a switching unit 22. The control unit 21 is communicatively connected to both the RF communication unit and the switching unit 22 in the compartment controller 2. The control unit 21 receives heating adjustment requests sent by the main thermostat 31 through the RF communication unit, thereby generating corresponding switching commands to control the operation of the switching unit 22. The switching unit 22 includes multiple water pump switches 221, each connected to a water pump. Each water pump corresponds to a heating zone, and thus each water pump switch 221 also corresponds to a heating zone. By controlling the action of the water pump switches 221, the opening and closing of the water pumps are controlled, thereby controlling the heating supply to the corresponding heating zone.

[0067] In one embodiment, Figure 3 This is a schematic diagram of the structure of a switching unit in a heating system according to this embodiment, as shown below. Figure 3 As shown, in addition to the water pump switch 221, the switch unit 22 also includes a driver chip 222. The input terminal of the driver chip 222 is connected to the control unit 21 and is used to receive the switch command sent by the control unit 21; the output terminal of the driver chip 222 is connected to multiple water pump switches 221 respectively and is used to control the operation of multiple water pump switches 221 based on the received switch command.

[0068] In one embodiment, the driver chip 222 has multiple input pins at its input terminal and multiple output pins at its output terminal; the multiple input pins correspond one-to-one with the multiple output pins. The driver chip 222 controls the operation of the water pump switch 221 by connecting the output pin corresponding to the input pin to the switch received from the input pin, based on the switching command received from the input pin.

[0069] In one embodiment, Figure 4 This is a circuit diagram of a water pump switch in a heating system according to this embodiment, as shown below. Figure 4As shown, a water pump switch 221 includes a relay KM1, a light-emitting diode D1, and a first resistor R1. One end of the drive coil of relay KM1 is connected to a power supply, and the other end is connected to the output terminal of the driver chip 222. Each contact switch of relay KM1 is connected to a corresponding water pump. When the input pin of the driver chip 222 receives a switch command indicating "on," the corresponding output pin outputs a high level, driving the drive coil of relay KM1 to generate current, attracting the contacts in the contact switches, causing the contact switches to close, thereby turning on the water pump and supplying heat to the corresponding heating area. When the input pin of the driver chip 222 receives a switch command indicating "off," the corresponding output pin outputs a low level, no current is generated in the drive coil of relay KM1, the contacts in the contact switches spring open, causing the contact switches to open, thereby turning off the water pump and stopping the supply of heat to the corresponding heating area.

[0070] In one embodiment, such as Figure 4 As shown, one end of the first resistor R1 is connected to the power supply and one end of the drive coil of relay KM1, and the other end of the first resistor R1 is connected to one end of LED D1. The other end of LED D1 is connected to the output terminal of driver chip 222 and the other end of the drive coil of relay KM1. The first resistor R1 acts as a protective resistor to protect LED D1 from breakdown. LED D1 is used to indicate the on / off status of the corresponding relay KM1 and water pump; when the output pin of driver chip 222 outputs a high level, LED D1 is forward-biased, indicating that relay KM1 is on and the water pump is on; when the output pin of driver chip 222 outputs a low level, LED D1 is reverse-biased, indicating that relay KM1 is off and the water pump is off.

[0071] In one embodiment, such as Figure 3 As shown, the switching unit 22 may include multiple driver chips 222. The number of driver chips 222 is configured according to the number of heating zones set in the heating system and the number of water pump switches 221 that the driver chips 222 can control. Figure 3 For example, in a heating system there are 8 water pumps, which means there are 8 heating zones. One driver chip 222 can control 7 water pump switches 221. Therefore, the switch unit 22 needs to be configured with 2 driver chips 222 to control 8 water pumps.

[0072] In one embodiment, such as Figure 3As shown, the switch unit 22 may also include a linkage switch; one end of the linkage switch is connected to the output terminal of the driver chip 222, and the other end of the linkage switch is connected to the heating device 1 in the heating system; the linkage switch is used to send a switching command to the heating device 1 to instruct the heating device 1 to turn on or off. Similarly, a relay is connected between the linkage switch and the output terminal of the driver chip 222. The control method of the linkage switch is the same as the control method of the water pump, and will not be described again here.

[0073] In one embodiment, such as Figure 3 As shown, the switching unit 22 may also include a three-way valve switch. One end of the three-way valve switch is connected to the output terminal of the drive chip 222, and the other end is connected to the three-way valve corresponding to the water valve. The three-way valve corresponding to the water valve is installed near the water valve in the heating system. Similarly, the three-way valve switch can be a relay. The control of the three-way valve switch and the three-way valve is the same as the control of the water pump switch 221 and the water pump, and will not be described again here.

[0074] In one embodiment, the compartment controller 2 may further include a function switching unit connected to the control unit 21. Figure 5 This is a circuit diagram of a function switching unit in a heating system according to this embodiment, as shown below. Figure 5 As shown, the function switching unit is equipped with a mode switching button SW1 and a function switching button SW2.

[0075] The mode switching button SW1 can switch the operating modes of the heating system, including automatic mode, fully open mode, and fully closed mode. Automatic mode controls the water pump switch 221 based on heating adjustment requests sent by the main thermostat 31 and the auxiliary thermostat 32. Fully open mode operates with the water pump, interlock switch, and three-way valve all open. Fully closed mode operates with the water pump, interlock switch, and three-way valve all closed. The fully open and fully closed modes are typically used during heating system commissioning and troubleshooting to check if the water pump, interlock switch, and three-way valve are functioning correctly. One end of the mode switching button SW1 is grounded. The other end of the button is connected to one end of the second resistor R2 and one end of the third resistor R3. The other end of the third resistor R3 is connected to the power supply. The other end of the second resistor R2 is connected to the control unit 21, sending the KEY1 signal corresponding to the mode switching button SW1 to the control unit 21. The second resistor R2 serves as a protection resistor to ensure circuit safety; the third resistor R3 serves as a pull-up resistor, pulling the signal output to the control unit 21 to a high level when the mode switch button SW1 is not pressed.

[0076] The function switch button SW2 can switch the control functions of the relays, including relay state switching, delay switch, and last-path delay switch. The relay state switching function switches the control mode for relays in different modes. Since the switching commands for relay circuits in different modes are different (for example, some relay circuits give a signal "1" to open the relay, while others give a signal "1" to close the relay), the control mode of the relay is switched to adjust the switching command output to the relay circuit. The delay switch function corresponds to a control mode that opens or closes the relay after receiving a switch command and then delays for a preset time. The last-path delay switch function corresponds to a control mode that controls the last closed relay to close after a preset time. One end of the function switch button SW2 is grounded, and the other end is connected to one end of the fourth resistor R4 and one end of the fifth resistor R5. The other end of the fifth resistor R5 is connected to the power supply. The other end of the fourth resistor R4 is connected to the control unit 21, sending the KEY2 signal corresponding to the function switch button SW2 to the control unit 21. The fourth resistor R4 serves as a protective resistor to ensure circuit safety; the fifth resistor R5 serves as a pull-up resistor, pulling the signal output to the control unit 21 to a high level when the function switch button SW2 is not pressed.

[0077] In one embodiment, the room controller 2 may further include an indicator light unit connected to the control unit 21. The indicator light unit includes multiple indicator lights, each corresponding to a heating zone, used to indicate whether heating is on in its corresponding zone. Optionally, the indicator light unit may also include indicator lights indicating other states, such as indicators showing the pairing status between the main thermostat 31 and the auxiliary thermostat 32, and between the main thermostat 31 and the room controller 2, fault alarm lights, and mode selection lights, etc.; the specific functions of the included indicator lights can be adjusted according to actual needs and are not specifically limited here.

[0078] In one embodiment, the compartment controller 2 may further include a buzzer connected to the control unit 21, which emits a corresponding prompt tone when the user performs a key operation. Optionally, the buzzer may emit different sound effects for different key operations to indicate different user actions.

[0079] In one embodiment, the compartment controller 2 may further include a power supply unit for converting AC power to DC power. The power supply unit may be a combination of circuits such as a rectifier circuit, a step-up / step-down circuit, and a voltage regulator circuit. The rectifier circuit converts AC to DC, the step-up / step-down circuit boosts or bucks the DC voltage to obtain the voltage required by the compartment controller 2, and the voltage regulator circuit stabilizes the DC voltage to prevent fluctuations. The specific circuit structures used for the rectifier circuit, step-up / step-down circuit, and voltage regulator circuit are not specifically limited here.

[0080] In this embodiment, the heating system uses a room controller 2 to control the heating of all heating areas, simplifying the system structure and improving the flexibility of the heating system control and scheduling. At the same time, the main thermostat 31 serves as a relay station for information transmission and communication between the auxiliary thermostat 32 and the room controller 2. The main thermostat 31 can filter the information transmitted by the auxiliary thermostat 32 and only send the data required by the room controller 2, that is, the data related to heating adjustment requests, to the room controller 2. This improves the data processing efficiency and response efficiency of the room controller 2 to heating adjustment requests, enabling the room controller 2 to quickly adjust the temperature of each heating area.

[0081] According to an embodiment of the present invention, in another aspect, a heating control method is also provided, which can be applied to any of the heating systems described above. Figure 6 This is a flowchart illustrating a heating control method according to this embodiment, as shown below. Figure 6 As shown, the method may include the following steps:

[0082] Step 610: The main temperature controller 31 and the auxiliary temperature controller 32 establish a communication connection based on the order in which they enter the code pairing state, and the main temperature controller 31 and the compartment controller 2 establish a communication connection based on the order in which they enter the code pairing state.

[0083] In this embodiment, the main temperature controller 31 and the auxiliary temperature controller 32, as well as the main temperature controller 31 and the compartment controller 2, establish communication connections by entering a pairing state. Since the main temperature controller 31 may establish communication connections with multiple auxiliary temperature controllers 32 sequentially, the order in which these auxiliary temperature controllers enter the pairing state relative to the main temperature controller 31 will differ. If only one pairing communication process is used, some auxiliary temperature controllers 32 may fail to pair with the main temperature controller 31 and thus fail to establish a communication connection. Therefore, different pairing communication processes are used according to the order in which the main temperature controller 31 and the auxiliary temperature controllers 32 enter the pairing state to establish communication connections. Similarly, the main temperature controller 31 and the compartment controller 2 also establish communication connections based on the order in which they enter the pairing state. Therefore, the pairing is performed according to the order in which the pairing state is entered, ensuring that the main temperature controller 31 and the auxiliary temperature controller 32, and the main temperature controller 31 and the compartment controller 2 can establish normal communication connections. At the same time, the user does not need to enter the pairing state of the main temperature controller 31 and the auxiliary temperature controller 32 or the compartment controller 2 in a specified order, which is convenient for the user.

[0084] In this embodiment, the order in which the main thermostat 31 establishes communication connections with the auxiliary thermostat 32, and the main thermostat 31 establishes communication connections with the compartment controller 2, is not limited. However, when the heating system is in use, the main thermostat 31 needs to establish a communication connection with the compartment controller 2 so that the compartment controller 2 can receive heating adjustment requests. The main thermostat 31 may not establish a communication connection with the auxiliary thermostat 32, or may only establish a communication connection with some of the auxiliary thermostats 32. That is to say, a communication connection can be established between the auxiliary thermostat 32 and the main thermostat 31 corresponding to a certain heating area only when the user needs to heat a certain heating area, thereby reducing the complexity of the heating system and improving the flexibility of the heating system configuration.

[0085] Step 620: When the temperature of the corresponding heating zone reaches the preset temperature, the secondary thermostat 32 sends the corresponding heating adjustment request to the primary thermostat 31.

[0086] In this embodiment, for each heating zone, the user can set the desired heating temperature and heating status on the corresponding secondary thermostat 32 or main thermostat 31, or modify the heating temperature and heating status of the corresponding secondary thermostat 32 or main thermostat 31 through the cloud; wherein, the heating status is the state indicating whether the heating of the heating zone corresponding to the main thermostat 31 or secondary thermostat 32 is turned on.

[0087] In this embodiment, the preset temperature is the temperature corresponding to triggering the heating adjustment request; the preset temperature includes a first preset temperature and a second preset temperature, wherein the first preset temperature corresponds to the heating adjustment request to turn on the heating, and the second preset temperature corresponds to the heating adjustment request to turn off the heating; that is, when the temperature of the heating area is detected to reach the first preset temperature, the secondary thermostat 32 generates a heating adjustment request corresponding to turning on the heating, and when the temperature of the heating area is detected to reach the second preset temperature, the secondary thermostat 32 generates a heating adjustment request corresponding to turning off the heating.

[0088] In this embodiment, the magnitudes of the first preset temperature and the second preset temperature are related to the heating temperature and the deviation temperature set in the auxiliary thermostat 32; when the deviation between the current temperature of the heating area and the heating temperature reaches the deviation temperature, a heating adjustment request is triggered. Specifically, the magnitude of the first preset temperature is equal to the difference between the heating temperature and the deviation temperature, and the magnitude of the second preset temperature is equal to the sum of the heating temperature and the deviation temperature.

[0089] In this embodiment, the steps for the main thermostat 31 to trigger and generate a heating adjustment request are the same as those for the secondary thermostat 32, and will not be described again here.

[0090] Step 630: The main thermostat 31 sends the heating adjustment request corresponding to the main thermostat 31 and / or the auxiliary thermostat 32 to the room controller 2.

[0091] In this embodiment, the main thermostat 31 acts as a data relay station for information transmission and communication between the secondary thermostat 32 and the room controller 2. It filters the data received from the secondary thermostat 32, identifies data related to heating adjustment requests, and sends the heating adjustment requests to the room controller 2. Simultaneously, if the main thermostat 31 also has its own heating adjustment request, it will also send its own heating adjustment request to the room controller 2.

[0092] In one embodiment, the main thermostat 31 also filters the data received from the secondary thermostat 32 and its own data, filters out the working data related to heating temperature and heating status, and synchronizes it to the cloud, so that users can view and adjust the relevant working data of all thermostats at the same time in the cloud.

[0093] Step 640: Based on the received heating adjustment request, the room controller 2 controls the start and stop of the water pump corresponding to the heating adjustment request.

[0094] In this embodiment, after receiving a heating adjustment request, the room controller 2 determines the target heating area corresponding to the request, as well as the specific adjustment type—whether to turn the heating on or off—and generates a corresponding on / off command. Based on the corresponding on / off command, it controls the start and stop of the water pump corresponding to the target heating area, thereby turning the heating on or off for that target heating area.

[0095] In a specific embodiment, taking the establishment of a communication connection between the main temperature controller 31 and the auxiliary temperature controller 32 as an example, the establishment of the communication connection in step 610 above, based on the order of entering the code pairing state, can include the following two cases:

[0096] In the first scenario, if the main temperature controller 31 enters the pairing state before the secondary temperature controller 32, then three pairing communication commands are executed. Specifically, after entering the pairing state, the secondary temperature controller 32 sends a pairing request command to the main temperature controller 31; upon receiving the pairing request command, the main temperature controller 31 sends an identification registration command to the secondary temperature controller 32; and upon receiving the identification registration command, the secondary temperature controller 32 sends a pairing success command to the main temperature controller 31 to establish a communication connection. This completes the three-way pairing process, confirming successful pairing between the main temperature controller 31 and the secondary temperature controller 32, and establishing a successful communication connection between them.

[0097] In the second scenario, if the main temperature controller 31 enters the pairing state after the secondary temperature controller 32, then two pairing communication commands are executed. Specifically, after entering the pairing state, the main temperature controller 31 sends an identification registration command to the secondary temperature controller 32; upon receiving the identification registration command, the secondary temperature controller 32 sends a pairing success command to the main temperature controller 31 to establish a communication connection. Thus, two handshake pairing operations are completed, confirming that the main temperature controller 31 and the secondary temperature controller 32 have successfully matched, and a communication connection has been successfully established between them.

[0098] In one embodiment, to facilitate the division controller 2 in determining the target heating area corresponding to the heating adjustment request, when the main thermostat 31 and the auxiliary thermostat 32 establish a communication connection, the auxiliary thermostat 32 is assigned a corresponding identifier or selected by the auxiliary thermostat 32. Specifically, during the aforementioned communication connection establishment process, after receiving the identifier registration instruction, the auxiliary thermostat 32 sends its corresponding identifier to the main thermostat 31. The identifier uniquely represents a auxiliary thermostat 32 and its corresponding heating area. Once an identifier is selected, it can no longer be selected by other auxiliary thermostats 32, thus ensuring a one-to-one correspondence between identifiers and heating areas. After receiving the identifier from the auxiliary thermostat 32, the main thermostat 31 sends the correspondence between the identifier of the auxiliary thermostat 32 and the corresponding heating area to the division controller 2. Correspondingly, the heating adjustment request may include the corresponding identifier, enabling the division controller 2 to determine the heating area corresponding to the heating adjustment request based on the identifier.

[0099] In one embodiment, the main thermostat 31 and the compartment controller 2 also have their corresponding identifiers; optionally, the identifiers corresponding to the main thermostat 31 and the compartment controller 2 can be assigned according to user settings or default settings during heating system initialization. Optionally, the selectable identifiers of the secondary thermostat 32 have an identifier selection list, and the identifiers corresponding to the main thermostat 31 and the compartment controller 2 are not in the identifier selection list corresponding to the secondary thermostat 32, thereby avoiding conflicts between the identifiers of the secondary thermostat 32 and the main thermostat 31 or the compartment controller 2.

[0100] In one embodiment, the identifier may be one or a combination of several forms such as numbers, letters, and symbols, without any specific limitation.

[0101] In one embodiment, in step 640 above, the compartment controller 2 includes a control unit 21 and a switching unit 22. The control unit 21 generates a corresponding switching command based on the received heating adjustment request, thereby controlling the start and stop of the water pump corresponding to the heating adjustment by switching the corresponding water pump switch 221 on and off, thus completing the heating adjustment of the target heating area. Specifically, Figure 7 This is a schematic diagram illustrating the process of controlling the start and stop of the water pump corresponding to the heating adjustment request in a heating control method according to this embodiment. Figure 7 As shown, step 640 above may include the following steps:

[0102] Step 710: The control unit 21 of the compartment controller 2 searches in the area correspondence based on the target identifier corresponding to the heating adjustment request to determine the target heating area.

[0103] In this embodiment, as described above, after receiving the identifier of the secondary thermostat 32, the main thermostat 31 sends the correspondence between the identifier of the secondary thermostat 32 and the heating area corresponding to the secondary thermostat 32 to the room controller 2. After receiving the correspondence between the identifier and the heating area, the room controller 2 can establish a region correspondence to represent the correspondence between the identifier and the heating area. The region correspondence includes the correspondence between the identifiers of all secondary thermostats 32 that have established communication connections with the main thermostat 31 and the heating areas. Based on the target identifier contained in the received heating adjustment request, the control unit 21 finds the heating area corresponding to the target identifier in the region correspondence and determines the heating area as the target heating area.

[0104] Step 720: The control unit 21 generates a switching command based on the target heating area and the adjustment type of the heating adjustment request.

[0105] In this embodiment, the control unit 21 determines the instruction value corresponding to the switch command based on the adjustment type of the heating adjustment request, and sends the switch command to the input pin corresponding to the driver chip 222 in the switch unit 22 based on the target heating area corresponding to the heating adjustment request. Specifically, if the adjustment type of the heating adjustment request is to turn on the heating, the instruction value corresponding to the switch command is set to a first preset value; if the adjustment type of the heating adjustment request is to turn off the heating, the instruction value corresponding to the switch command is set to a second preset value.

[0106] In one embodiment, the setting of the first preset value and the second preset value are related to the driver chip 222 used in the switching unit 22. If the input signal and output signal of the driver chip 222 are out of phase, that is, when the input signal is low, the output signal is high, and when the input signal is high, the output signal is low, then the first preset value is 0 and the second preset value is 1; if the input signal and output signal of the driver chip 222 are in phase, that is, when the input signal is low, the output signal is low, and when the input signal is high, the output signal is high, then the first preset value is 1 and the second preset value is 0.

[0107] Step 730: Based on the switching command, the control unit 21 controls the on / off state of the water pump switch 221 corresponding to the target heating area, so as to control the start and stop of the water pump corresponding to the heating adjustment request.

[0108] In this embodiment of the invention, the control unit 21 sends a switch command to the input pin corresponding to the target heating area in the driver chip 222. After receiving the switch command, the driver chip 222 controls the on / off state of the water pump switch 221 connected to the corresponding output pin, thereby controlling the on / off state of the water pump switch 221 corresponding to the target heating area and completing the control of the corresponding water pump. Specifically, if the driver chip 222 receives a switch command indicating to turn on heating, it controls the water pump switch 221 connected to the corresponding output pin to turn on, thereby controlling the corresponding water pump to turn on and enabling the heating device to supply heat to the target heating area; if the driver chip receives a switch command indicating to turn off heating, it controls the water pump switch 221 connected to the corresponding output pin to turn off, thereby controlling the corresponding water pump to turn off and enabling the heating device to stop supplying heat to the target heating area.

[0109] In one embodiment, to improve the convenience of the heating system, the room controller 2 can also perform linkage adjustment on the heating device 1 based on received heating adjustment requests. The heating device 1 is turned on whenever there is a heating adjustment request indicating that heating should be turned on, so that the user does not need to manually turn on the heating device 1 when heating is needed. Conversely, the heating device 1 is turned off when all heating adjustment requests indicate that heating should be turned off, so that the user does not need to manually turn off the heating device 1 when heating is not needed. Specifically, if there is a switch command indicating that heating should be turned on, the linkage switch is controlled to close to send an on command to the heating device 1; if there is no switch command indicating that heating should be turned on, the linkage switch is controlled to open to send a off command to the heating device 1.

[0110] The heating control method of the present invention uses a room controller 2 to control the heating of all heating areas, simplifying the system structure of the heating system and improving the flexibility of the heating system control and scheduling. At the same time, the main thermostat 31 serves as a relay station for information transmission and communication between the auxiliary thermostat 32 and the room controller 2. The main thermostat 31 can filter the information transmitted by the auxiliary thermostat 32 and only send the data required by the room controller 2, that is, the data related to the heating adjustment request, to the room controller 2. This improves the data processing efficiency and response efficiency of the room controller 2 to the heating adjustment request, enabling the room controller 2 to quickly adjust the temperature of each heating area.

[0111] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0112] The specific embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
