Description

Technical Field

[0001] This invention relates to the field of central range hood technology, and in particular to a network verification method and system for central range hoods. Background Technology

[0002] The central range hood system uses a main unit on the rooftop as the exhaust power source for the entire building. It creates negative pressure in the central flue and the branch flues entering each user's home. Each user's home is equipped with a power distribution valve (or damper). By adjusting the opening angle of the power distribution valve, the suction power of the user's kitchen is adjusted. When the air volume required by each user in the building exceeds the air volume provided by the main unit, the fan frequency of the rooftop main unit is adjusted to regulate the air volume. The damper controller adjusts the opening angle of the dampers based on the on / off status of the dampers in other users' homes to achieve balanced air volume.

[0003] Before formal delivery, the entire central range hood system requires functional testing and verification to ensure proper interaction between each terminal and the main unit. The status of the exhaust ducts within the system also needs to be verified. Each terminal of the central range hood has a unique device code and must be assigned a corresponding and correct floor number. Incorrect floor numbering will cause network anomalies, preventing the main unit from controlling the terminals and thus hindering proper exhaust. Furthermore, abnormal exhaust duct status will also affect the exhaust performance of the central range hood. Summary of the Invention

[0013] In one embodiment, the method further includes:

[0015] After outputting the result that the target floor network is normal, the following is also included:

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Figure 1 This is a flowchart illustrating a network verification method for a central range hood provided in an embodiment of the present invention, as shown below. Figure 1 As shown, this embodiment of the invention provides a network verification method for a central range hood, including:

[0045] Step S1: When the network verification signal is detected, the host starts and controls the air valves of the terminals on the target floor to maintain the same angle, and continuously detects the air volume of each terminal.

[0046] Specifically, in this embodiment, the specific structural diagram of the central range hood system can be as follows: Figure 2 As shown, the exhaust duct can be divided into floor-level exhaust ducts and a common exhaust duct. Floor-level exhaust ducts can be further categorized as first-floor, second-floor, third-floor, etc., depending on the floor level. The main exhaust unit is located at the top of the common exhaust duct to extract and remove smoke. Upon detecting network verification information for the central range hood system, the main unit can be controlled to start at a fixed frequency to extract smoke, while simultaneously controlling the air valves of the terminals on the target floor to maintain the same angle. The target floor can be the verification sequence in the network verification signal. For example, if the verification sequence is from top to bottom or bottom to top within the floor, the target floor would be the top or bottom floor. The target floor can also be a specific floor; no further limitations are specified here. During the extraction process, the airflow of each terminal is continuously monitored. The specific structural diagram of the terminal can be shown below. Figure 3 As shown, the system includes a range hood 100, a damper 200, a damper controller 300, and an airflow detection device 400. The damper controller 300 is connected to the damper 200 and the airflow detection device 400. The range hood 100 is also connected to the damper 200 and the damper controller 300. The airflow detection device 400 consists of a sampling tube 402 and a detection box 401. The damper controller 300 determines the operating status of the range hood 100, thereby controlling the opening angle of the damper 200. The airflow detection device 400 acquires the terminal airflow through the sampling tube 402 and forwards the acquired airflow to the exhaust fan via the damper controller 300 through the detection box 402.

[0047] Step S2: Detect the floor flue air volume of the target floor, obtain the sum of the air volume of the terminal air volume of the target floor, and determine whether the difference between the sum of the air volume and the floor flue air volume exceeds a preset threshold.

[0048] Specifically, the air volume of the target floor's flue is detected by the corresponding air volume detection module on each floor, and the air volume of all terminals on the target floor is calculated based on the terminal air volume received by the smoke exhaust host. The difference between the sum of the air volume and the floor flue air volume is also calculated. The difference can be reasonable errors such as the loss of air volume transmission in the flue, air volume acquisition error, etc.

[0049] In addition, when the difference between the air volume and the air volume of the floor flue exceeds the preset threshold, it indicates that the air volume loss between the terminal air volume and the floor flue air volume is not within the normal range when the smoke exhaust duct is ventilating. The smoke exhaust duct is in an abnormal state and may be malfunctioning. In this case, smoke exhaust duct abnormality information is generated and sent to the corresponding cloud platform or bound terminal so that relevant personnel can understand the corresponding abnormal situation and carry out timely maintenance of the smoke exhaust duct.

[0050] Step S3: When the difference between the air volume and the air volume of the floor flue does not exceed a preset threshold, the terminals are sorted based on the air volume of the terminals, the corresponding sorting number is determined, and it is determined whether the sorting number corresponds to the preset number of the terminal.

[0051] Specifically, when the difference between the air volume and the air volume in the floor smoke duct does not exceed a preset threshold, it indicates that the air volume loss between the terminal air volume and the floor smoke duct air volume is within the normal range during smoke exhaust duct operation, and the smoke exhaust duct is in normal condition, including the floor smoke duct and the common smoke exhaust duct. Then, the terminals are sorted based on their air volume, and corresponding sorting numbers are determined. For example, the terminals on the first floor are numbered 1-1, 1-2, 1-3, etc., based on their air volume. Here, the preceding "1" represents the target floor, and the following "1, 2, 3" represent the air volume. The sorting order can be from smallest to largest air volume. Then, it is determined whether the sorting number corresponds to the preset number of the terminal. The preset number can be determined based on the physical location of the terminal, for example, based on... Figure 3 The distance between the central terminal and the public smoke exhaust passage is set with a corresponding preset number.

[0052] Step S4: When the sorting number does not correspond to the preset number corresponding to the terminal, the preset number is updated based on the sorting number.

[0053] Specifically, when the sorting number does not correspond to the preset number of the terminal, it indicates that the terminal on that floor has a network abnormality and the floor number of the terminal is set incorrectly. In this case, the preset number is updated based on the sorting number to correct the preset number of the terminal.

[0054] In addition, after updating the preset number, the terminal air volume can be rechecked to obtain the terminal air volume again, i.e., the recheck air volume. Based on the air volume of the recheck air volume, the recheck number of the corresponding terminal is determined. It is then determined whether the recheck number corresponds to the updated preset number. When the recheck number corresponds to the updated preset number, it indicates that the network anomaly has been resolved, and the result of normal network connection of the target floor is output.

[0055] Additionally, when the sorting number corresponds to the preset number of the terminal, it indicates that there is no network abnormality on the target floor, and the result of normal network connection for the target floor is output. After outputting the result of normal network connection for the target floor (including cases where there is no network abnormality on the target floor and the result of normal network connection is output, or cases where there is a network abnormality on the target floor but the network abnormality has been resolved after updating the preset number and the result of normal network connection is output), the floor of the flue connected to the host is obtained, for example, such as... Figure 3 The system automatically checks other floors after the target floor has been checked.

[0056] This invention provides a network verification method for a central range hood. When a network verification signal is detected, the control host starts and controls the air valves of the terminals on the target floor to maintain the same angle, continuously detecting the airflow of each terminal; it also detects the airflow of the floor duct of the target floor and obtains the sum of the airflow of the terminals on the target floor, determining whether the difference between the sum of the airflow and the floor duct airflow exceeds a preset threshold; when the difference between the sum of the airflow and the floor duct airflow does not exceed the preset threshold, the terminals are sorted based on their airflow, a corresponding sorting number is determined, and it is determined whether the sorting number corresponds to a preset number corresponding to the terminal; when the sorting number does not correspond to the preset number corresponding to the terminal, the preset number is updated based on the sorting number. This allows the central range hood to detect the status of the exhaust duct while simultaneously determining the correctness of the system network through the terminal number settings.

[0057] In another embodiment, this embodiment provides a network verification method for a central range hood, and can also be as follows: Figure 4 As shown, it includes:

[0058] The verification process for the central range hood exhaust duct and network can be divided into two sub-processes: the first is the exhaust duct verification process, and the second is the floor network verification process.

[0059] Step S100: The main unit starts at a fixed frequency and performs ventilation;

[0060] Step S101: Open all terminal air valves on the same floor at the same angle;

[0061] Step S102: Detect the total air volume Q of the flue gas duct and the terminal air volume of this floor, and send them to the host;

[0062] Step S103: Sum the detected airflow of each terminal, the total airflow of the terminals is Q;

[0063] Step S104: Determine whether the difference between Q_total and Q_sum exceeds the threshold. If yes, proceed to step S105; otherwise, proceed to step S200.

[0064] Step S105: The main unit determines that the status of the smoke exhaust duct is abnormal;

[0065] Step S200: The main unit determines that the exhaust duct is in normal condition;

[0066] Step S201: Sort each terminal according to its air volume to obtain the sorting number of each terminal.

[0067] Step S202: Determine whether the sorting number of each terminal corresponds to the preset number. If not, proceed to step S203; if yes, proceed to step S206.

[0068] Step S203: The host determines that the network topology on this floor is abnormal;

[0069] Step S204: Update the preset number on the terminal;

[0070] Step S205: Recheck the air volume of each terminal on this floor, and return to step S201 after completion;

[0071] Step S206: The host determines that the network on this floor is normal;

[0072] After each step S206 is completed, you can return to step S101 until the smoke exhaust duct and network verification of the entire building is completed.
