Description

Technical Field

[0001] This application relates to the field of air conditioning equipment control technology, and in particular to a control method, control equipment and computer storage medium for a multi-zone control system. Background Technology

[0002] Currently, in partition control systems with multiple partition controllers, the usual approach to any communication failure is to either shut down the entire partition control system or maintain the operating state as it was before the communication failure.

[0003] However, shutting down the entire zone control system would directly interrupt the user's original temperature control needs, causing inconvenience. If the operating status before the communication failure is maintained, the total air volume may be too large or too small due to failure to adjust according to the real-time situation, which may affect the user's comfort or lead to unnecessary energy consumption.

[0004] Therefore, optimizing the communication fault response strategy of the partition control system to improve the user experience is an urgent problem to be solved. Summary of the Invention

[0012] If the time interval between the last communication time of the partition controller and the current time exceeds a preset offline time, the partition controller is determined to be in an offline state, and the partition controller is designated as the target partition controller.

[0013] In one embodiment, after the step of recording the last communication time of the partition controller, the method further includes:

[0014] If the time interval between the last communication time of the partition controller and the current time does not exceed the preset offline time, the partition controller is determined to be in a normal state.

[0015] In one embodiment, the step of periodically obtaining the offline duration of the target partition controller includes:

[0018] When the offline time of the target zone controller is within a preset first time interval, the air conditioning equipment is maintained to operate according to the current operating parameters.

[0019] In one embodiment, the step of determining the operating parameters of the air conditioning equipment based on the offline duration of the target zone controller further includes:

[0020] When the offline time of the target zone controller is within a preset second time interval, the weight of the opening degree of each air valve under the target zone controller is continuously adjusted according to a preset time function, and the air volume requirement is calculated according to the new weight. The start time of the second time interval is greater than the end time of the first time interval.

[0021] The airflow speed of the air conditioning device is determined based on the airflow requirement.

[0022] In one embodiment, the step of determining the operating parameters of the air conditioning equipment based on the offline duration of the target zone controller includes:

[0023] When the offline time of the target zone controller is within the preset third time interval, the opening of each air valve under the target zone controller operates at the default opening. The start time of the third time interval is greater than the end time of the second time interval.

[0024] Calculate the air volume requirement based on the opening degree of each air valve under the target zone controller;

[0025] The airflow speed of the air conditioning device is determined based on the airflow requirement.

[0026] In one embodiment, the step of determining the operating parameters of the air conditioning equipment based on the offline duration of the target zone controller includes:

[0027] When the offline duration of the target partition controller is within the third duration interval, a new global temperature limit condition is determined;

[0028] The target temperature of the air conditioning equipment is determined based on the new global temperature constraints.

[0036] This application provides a control method for a multi-zone control system. First, the target zone controller that is offline is identified. Then, the offline duration of the target zone controller is periodically acquired. Finally, the operating parameters of the air conditioning equipment are determined based on the offline duration of the target zone controller, so as to ensure that the multi-zone control system can still maintain a relatively reasonable and efficient working state even when some zone controllers are offline.

[0037] Therefore, this application achieves dynamic perception and adjustment of the system status by identifying the offline zone controller and periodically monitoring its offline duration. When the zone controller is offline, the operating parameters of the air conditioning equipment can be automatically adjusted to ensure that the system can optimize energy efficiency while ensuring the user's basic temperature control needs. This improves the flexibility and stability of the zone control system in the face of communication failures, thereby bringing a better user experience. Attached Figure Description

[0046] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0047] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0048] Currently, in partition control systems with multiple partition controllers, the usual approach to any communication failure is to either shut down the entire partition control system or maintain the operating state as it was before the communication failure.

[0049] However, shutting down the entire zone control system would directly interrupt the user's original temperature control needs, causing inconvenience. If the operating status before the communication failure is maintained, the total air volume may be too large or too small due to failure to adjust according to the real-time situation, which may affect the user's comfort or lead to unnecessary energy consumption.

[0050] Therefore, optimizing the communication fault response strategy of the partition control system to improve the user experience is an urgent problem to be solved.

[0051] The main solution of this application embodiment is: to determine the target zone controller that is offline; to periodically obtain the offline duration of the target zone controller; and to determine the operating parameters of the air conditioning equipment based on the offline duration of the target zone controller.

[0052] This application embodiment achieves dynamic perception and adjustment of the system status by identifying the offline zone controller and periodically monitoring its offline duration. When the zone controller is offline, the operating parameters of the air conditioning equipment can be automatically adjusted to ensure that the system can optimize energy efficiency while ensuring the user's basic temperature control needs. This improves the flexibility and stability of the zone control system in the face of communication failures, thereby bringing a better user experience.

[0053] The executing entity in this embodiment can be a control device, which can be a control terminal in a multi-zone control system that controls air conditioning equipment such as air conditioners, such as a main controller. This embodiment does not specifically limit this. Air conditioning equipment refers to equipment that processes the air in a workspace to maintain a set temperature and humidity, and to control the levels of dust and harmful gases in the workspace. Air conditioning equipment can be air conditioners, dehumidifiers, humidifiers, etc., and this embodiment does not specifically limit this either. The following description uses the main controller in a multi-zone control system as the executing entity to illustrate this embodiment and the subsequent embodiments.

[0054] Based on this, this application proposes a control method for a multi-zone control system according to the first embodiment. Please refer to [link / reference]. Figure 1 The control method for a multi-zone control system includes steps S10 to S30:

[0055] Step S10: Determine the target partition controller that is offline;

[0056] It should be noted that a multi-zone control system refers to a system that divides the overall system into multiple independent but interconnected control zones, and manages and controls each zone separately. Each zone is equipped with a corresponding zone controller for control, and the zone controller communicates with the main controller of the multi-zone control system.

[0057] The main controller detects the status of each partition controller in the system and identifies the target partition controller that is currently offline. The offline partition controller may be due to communication interruption caused by network failure, equipment failure or other reasons.

[0058] In one feasible implementation, step S10 may include steps S101 to S102:

[0059] Step S101: Record the last communication time of the partition controller;

[0060] The main controller continuously communicates with each partition controller and records the last communication time with each partition controller. This time represents the moment when the partition controller last successfully communicated with the main controller.

[0061] Step S102: When the time interval between the last communication time of the partition controller and the current time exceeds the preset offline time, the partition controller is determined to be in an offline state, and the partition controller is selected as the target partition controller.

[0062] The main controller periodically or in real time checks the time interval between the last communication time of each partition controller and the current time. This time interval is used as the basis for determining whether the partition controller is offline. By comparing the time interval with a preset offline time threshold, if the time interval exceeds the preset offline time threshold, the partition controller is determined to be offline. The offline time threshold can be set based on the actual application scenario, and this embodiment does not impose specific limitations on it.

[0063] It is worth mentioning that, in one feasible implementation, the main controller periodically sends status query information to the partition controller. Under normal communication conditions, the partition controller will reply to the information sent by the main controller. If the main controller does not receive a reply from the partition controller within a preset response time, the main controller starts timing. That is, in this embodiment, the current time is determined when the partition controller does not respond to the status query information. When this timing time exceeds the preset offline time, the main controller determines that the partition controller is in an offline state.

[0064] In another feasible implementation, the main controller sets a separate timer that triggers cyclically. Whenever the timer triggers, the main controller calculates the time interval between the timer trigger time and the last communication time of the partition controller. In this embodiment, the time when the timer triggers is taken as the current time. If this time interval exceeds the preset offline time, the partition controller is determined to be in an offline state.

[0065] The above are just two feasible implementation methods for determining the current time provided in this embodiment. This embodiment does not specifically limit the specific implementation method of step S102.

[0066] In one possible implementation, step S101 may be followed by step S103:

[0067] Step S103: If the time interval between the last communication time of the partition controller and the current time does not exceed the preset offline time, the partition controller is determined to be in normal state.

[0068] Obtain the last communication time of the partition controller and compare it with the current time to calculate the time interval between the two. Then compare this time interval with the preset offline time. If the time interval is less than or equal to the preset offline time, it is determined that the partition controller is currently in a normal state, that is, the partition controller can maintain effective communication with the main controller within the preset offline time range.

[0069] Step S20: Periodically obtain the offline duration of the target partition controller;

[0070] Based on a pre-set time interval, the offline duration of the target partition controller is periodically checked and recorded, thereby obtaining the total duration of the target partition controller from the start of its offline state to the current moment.

[0071] In one possible implementation, step S20 may include step S201:

[0072] Step S201: Periodically calculate the time interval between the last communication time of the partition controller and the current time to obtain the offline duration of the target partition controller.

[0073] The master controller periodically calculates the time interval between the last communication time of the partition controller and the current time. This time interval represents the offline duration of the target partition controller.

[0074] For example, after the main controller determines that the target partition controller is offline, it will still periodically send a new status query message to the target partition controller. If the target partition controller cannot respond while offline, the main controller will determine the time when the target partition controller does not respond to the new status query message as the new current time, and determine the time interval between the new current time and the last communication time of the target partition controller as the offline duration of the target partition controller.

[0075] In one feasible implementation, if the target partition controller replies to the master controller with a new status query, the master controller can update the last communication time of the target partition controller. If it is determined that the time interval between the current time and the last communication time does not exceed the preset offline duration, the master controller can determine that the target partition controller has recovered from the offline state to the normal state and clear the recorded offline duration of the target partition controller.

[0076] Step S30: Determine the operating parameters of the air conditioning equipment based on the offline duration of the target zone controller.

[0077] After obtaining the offline duration of the target zone controller, the operating parameters of the air conditioning equipment are adjusted according to the offline duration. These operating parameters include the target temperature and fan speed of the air conditioning equipment, ensuring that the air conditioning equipment can still maintain a reasonable operating state even when the zone controller is offline, so as to minimize the impact on user comfort.

[0078] Therefore, this embodiment achieves dynamic perception and adjustment of the system status by identifying the offline zone controller and periodically monitoring its offline duration. When the zone controller is offline, the operating parameters of the air conditioning equipment can be automatically adjusted to ensure that the system can optimize energy efficiency while ensuring the user's basic temperature control needs. This improves the flexibility and stability of the zone control system in the face of communication failures, thereby bringing a better user experience.

[0079] Based on the first embodiment described above, a second embodiment of the control method for the multi-zone control system of this application is proposed. In the second embodiment, step S30 may include step S301:

[0080] Step S301: When the offline time of the target zone controller is within the preset first time interval, maintain the air conditioning equipment operating according to the current operating parameters.

[0081] When the offline time of the target zone controller is within the preset first time interval, it means that the offline time of the target zone controller is still relatively short. At this time, the air conditioning equipment can continue to operate according to the current operating parameters to avoid frequent adjustment of the operating parameters of the air conditioning equipment due to the short-term offline of the controller, maintain the stability of the system and reduce unnecessary energy consumption. The first time interval can be set according to the actual application scenario, and this embodiment does not make a specific limitation on it.

[0082] For example, if the first time interval is set to three minutes to one hour, the main controller will not adjust the operating parameters of the air conditioning equipment when the offline time of the target zone controller is within the first time interval.

[0083] In one feasible implementation, step S30 may further include steps S302 to S303:

[0084] Step S302: When the offline time of the target zone controller is within the preset second time interval, the weight of the opening degree of each air valve under the target zone controller is continuously adjusted according to the preset time function, and the air volume requirement is calculated according to the new weight. The start time of the second time interval is greater than the end time of the first time interval.

[0085] It should be noted that each zone controller can be wired to multiple air valves in the controlled zone and control the opening degree of the air valves. The operating parameters of the air conditioning equipment include air speed.

[0086] When the offline time of the target partition controller is within the preset second time interval, the main controller begins to take measures to deal with the potential system performance degradation caused by the offline of the partition controller. The start time of the second time interval is greater than the end time of the first time interval. Usually, the first time interval and the second time interval are continuous in time, that is, the end of the first time interval is immediately followed by the start of the second time interval, without any time interval or break.

[0087] When the offline time of the target zone controller is within the preset second time interval, the main controller continuously adjusts the weight of the opening degree of each air valve under the target zone controller according to the preset time function. By adjusting the weight of the air valve opening degree, the air volume of the air conditioning equipment can be set and allocated more flexibly to meet the air volume requirements of different zones.

[0088] It is worth mentioning that the time function can be a time-related linear function, exponential function, or other form of function, depending on the system's expectations and coping strategies for performance degradation caused by the offline partition controller. In this embodiment, the time function is not specifically limited.

[0089] Step S303: Determine the airflow speed of the air conditioning equipment based on the airflow requirements.

[0090] After adjusting the weights of the opening degrees of each damper under the target zone controller, the main controller will calculate the air volume requirement of the air conditioning equipment based on the new weights. This air volume requirement reflects the total air volume required by the system to meet the needs of each zone when the target zone controller is offline. Then, the air speed of the air conditioning equipment is determined based on the calculated air volume requirement.

[0091] It should be noted that when the offline time of the target zone controller is in the second time interval, the main controller cannot obtain the opening status of each air valve under the target zone controller, and cannot determine whether the air valve is currently running and its opening. Therefore, in order to avoid the opening status of each air valve under the target zone controller affecting other zones in the system, the weight of each air valve opening under the target zone controller can be continuously reduced according to a preset time function. That is, the longer the offline time of the target zone controller, the smaller the impact of each air valve opening under the control of the target zone on the calculation of the air conditioning equipment wind speed, thereby ensuring that the multi-zone control system can still maintain stable operation and high efficiency even when the zone controller is offline.

[0092] In one feasible implementation, step S30 may further include steps S304 to S306:

[0093] Step S304: When the offline time of the target zone controller is within the preset third time interval, the opening of each air valve under the target zone controller is operated at the default opening. The start time of the third time interval is greater than the end time of the second time interval.

[0094] When the offline time of the target zone controller reaches the preset third time interval, it can be determined that the target zone controller has been offline for a long time. Based on the existing system mechanism, the opening degree of the air valve under the target zone controller can be determined to be the default opening degree. This default opening degree is usually preset according to the system's operating experience and actual needs, which can ensure that even when the target zone controller is offline, a certain air volume distribution can still be maintained in its workspace to meet the basic air volume requirements of the zone.

[0095] When the offline time of the target zone controller reaches the preset third time interval, the main controller determines the opening degree of each air valve under the target zone controller to be the default opening degree. The start time of the third time interval is greater than the end time of the second time interval. Usually, the second time interval and the third time interval are continuous in time, that is, the end of the second time interval is immediately followed by the start of the third time interval, without any time interval or break.

[0096] Step S305: Calculate the air volume requirement based on the opening degree of each damper under the target zone controller;

[0097] After the damper opening under the target zone controller is set to the default opening, the main controller calculates the air volume requirement of the air conditioning equipment based on the opening of each damper under the target zone controller and the actual damper opening under other zone controllers in normal conditions.

[0098] Step S306: Determine the airflow speed of the air conditioning equipment based on the airflow requirements.

[0099] Based on the calculated air volume requirements, the fan speed of the air conditioning equipment is further determined. By adjusting the fan speed, it can be ensured that the air conditioning equipment can output sufficient air volume to meet the air volume requirements of each zone, while maintaining the stability of the system.

[0100] In one feasible implementation, step S30 may further include steps S307 to S308:

[0101] Step S307: When the offline duration of the target partition controller is in the third duration interval, determine the new global temperature limit condition;

[0102] It should be noted that the operating parameters of air conditioning equipment also include the target temperature.

[0103] When the target zone controller is offline for an extended period of time, in addition to adjusting the airflow speed of the downflow valve of the target zone controller, the main controller can determine new global temperature limits. These global temperature limits may include maximum temperature limits, minimum temperature limits, or temperature fluctuation ranges, to ensure that the air conditioning equipment can still maintain a reasonable temperature environment when the target zone controller is offline.

[0104] Step S308: Determine the target temperature of the air conditioning equipment based on the new global temperature constraints.

[0105] The target temperature of the air conditioning equipment is determined based on the new global temperature limit conditions. Specifically, the new global temperature limit conditions do not take into account the target temperatures of the sub-controllers connected to the target zone controller.

[0106] Therefore, in this embodiment, by identifying the offline zone controller and periodically monitoring its offline duration, different processing strategies are adopted for different offline durations. When the zone controller is briefly offline, the current operating parameters of the air conditioning equipment are maintained to avoid unnecessary adjustments. When the offline duration of the zone controller is prolonged, the operating parameters of the air conditioning equipment are gradually adjusted to ensure system stability and low energy consumption. When the zone controller is offline for a long time, the airflow distribution and temperature control of the air conditioning equipment are further adjusted to ensure that the system can optimize energy efficiency while ensuring the user's basic temperature control needs. This improves the flexibility and stability of the zone control system in the face of communication failures, thereby bringing a better user experience.

[0107] For example, to help understand the implementation flow of the control method for the multi-zone control system obtained by combining the above embodiments, please refer to... Figure 2 , specifically:

[0108] In a multi-zone control system, the main controller continuously communicates with each zone controller and records the last communication time with each zone controller. When the time interval between the last communication time of a zone controller and the current time exceeds a preset offline time, the zone controller is determined to be offline, and a prompt message is output to the user to indicate that the zone controller is offline. This zone controller is then designated as the target zone controller. The offline duration of the target zone controller is obtained. If the offline duration of the target zone controller falls within a first duration interval, the corresponding time period is designated as a maintenance period, during which the operating parameters of the air conditioning equipment are not adjusted. If the offline duration of the target zone controller falls within a second duration interval, the second time interval is designated as a maintenance period. The time period corresponding to the long interval is the gradual change zone. During this period, the weight of the opening degree of all air valves under the target zone controller in the air volume demand algorithm continuously decreases according to the time function. The main controller recalculates the air volume demand and changes the air speed of the air conditioning equipment every once in a while. If the offline time of the target zone controller is in the third time interval, the time period corresponding to the third time interval is the steady state zone. The opening degree of all air valves under the target zone controller is updated to the default opening degree. The target temperature of all sub-controllers connected to it is no longer used as the global air conditioning temperature limit condition. The main controller recalculates the operating parameters such as the air speed and target temperature of the air conditioning equipment and sends the new operating parameters to the air conditioning equipment so that the air conditioning equipment can operate according to the new operating parameters.

[0109] To better understand the implementation process of the control method for the multi-zone control system in this example, the following example is provided:

[0110] like Figure 3 As shown, the multi-zone control system has one main controller, three zone controllers (A, B, and C), and one air conditioner. The preset offline time is 3 minutes, the first time interval is 3 minutes to 1 hour, the second time interval is 1 hour to 4 hours, and the third time interval is more than 4 hours.

[0111] The main controller continuously communicates with zone controllers A, B, C and the air conditioning equipment, and records the last communication data response time with each zone controller, i.e. the last communication time. Let's assume the last communication time with zone controller A is Tp.

[0112] The current time Tc is 7:00, and the main controller has detected that the last communication time Tp of partition controller A was 6:56.

[0113] If Tc-Tp is greater than the preset offline time of 3 minutes, partition controller A is determined to be offline. The offline time ΔT1 = 7:00 is recorded, and partition controller A is confirmed to be the target partition controller A in an offline state.

[0114] When the current time is between 7:00 and 8:00, that is, when the offline time of the target zone controller A is within the first time interval, the main controller will not adjust the operating parameters such as the set temperature and fan speed of the air conditioner, and will maintain the current state.

[0115] The current time is between 8:00 and 11:00, meaning the offline time of target zone controller A falls within the second time interval. In the air conditioning air volume demand algorithm, the weight of the opening degree of all air valves under target zone controller A decreases linearly according to a time function. The main controller recalculates the air volume demand every minute and adjusts the air conditioning fan speed according to the new demand.

[0116] Since the current time is after 11:00, meaning the offline time of target zone controller A is in the third time interval, the main controller updates the opening degree of all air valves under target zone controller A to the default opening degree (e.g., 50%) in the air conditioning air volume demand algorithm. The target temperature of all sub-controllers connected to zone controller A is no longer used as a global air conditioning temperature limit condition. The main controller recalculates the air conditioning fan speed and the new air conditioning target temperature, and sends the new parameters to the air conditioning equipment.

[0117] It should be noted that this example is only for the purpose of assisting in understanding this application and does not constitute a limitation on the control method of the multi-zone control system of this application. Any simple modifications based on this technical concept are within the protection scope of this application.
