Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a water valve fault management system, method, device and air conditioner. Background Art

[0002] At present, the proportion of chilled water cooling in air conditioning refrigeration is gradually increasing, and the key to controlling the cooling capacity of chilled water lies in the control of the water valve. Therefore, once the water valve fails, it will have a great impact on air conditioning refrigeration. There are many reasons for water valve failure, such as foreign matter blockage, rust on the water valve, and communication disconnection. In general, water valve failure can be divided into two categories. One is that the water valve itself is stuck due to physical influence, and the other is that there is a problem with the communication that causes the water valve to be out of control, resulting in failure.

[0003] Prior art CN115711455A provides a method for detecting a fault in an air-conditioning chilled water valve, which establishes a wireless communication connection and determines whether the water valve is faulty by the difference between the actual opening of the chilled water valve and the target opening. The defect of this method is that when a wireless communication connection cannot be established or the communication connection is interrupted, it is impossible to accurately know the water valve opening, and it is also impossible to accurately determine whether the water valve is faulty. Therefore, how to accurately identify a water valve fault is a problem that needs to be solved by those skilled in the art. In addition, after detecting that a water valve fault has occurred, how to adjust and control it in a timely manner so that the overall operation of the air conditioner is not affected is also a problem that needs to be solved by those skilled in the art.

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0059] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0060] See below Figure 1 and Figure 2 , an embodiment of the present invention provides a water valve fault management system, comprising:

[0061] Mainboard controller 1;

[0062] A plurality of water valves 2 arranged in parallel, each of the water valves 2 is communicatively connected to the mainboard controller 1;

[0063] An opening measurement component 3, used to obtain the opening of the water valve 2;

[0064] The mainboard controller 1 is used to determine whether there is a communication fault corresponding to the water valve 2 according to the communication status of the water valve 2, and to determine whether there is a physical fault corresponding to the water valve 2 according to the opening degree of the water valve 2.

[0065] This embodiment determines whether there is a communication fault in the water valve 2 based on whether the mainboard controller 1 and the water valve 2 have established a communication connection, that is, if the mainboard controller 1 and the water valve 2 have not established a communication connection, it indicates that there is a communication fault in the water valve 2. At the same time, the opening of the water valve 2 is obtained based on the opening measurement component 3, so as to determine whether there is a physical fault in the water valve 2 according to the opening, that is, if the opening of the water valve 2 is abnormal, it indicates that there is a physical fault in the water valve 2. In addition, this embodiment also sets up a plurality of parallel water valves 2, so that when any water valve 2 fails, the mainboard controller 1 can switch the currently failed water valve 2 to other normal water valves 2, thereby ensuring that the air conditioner can operate smoothly and reliably. Therefore, this embodiment can not only accurately identify water valve faults, but also regulate the water valve after identifying the fault to meet the overall operation requirements of the air conditioner.

[0066] In one embodiment, the opening measurement component 3 includes a plurality of infrared laser sensors, and the plurality of infrared laser sensors are respectively disposed on the dial 21 of each of the water valves 2 .

[0067] like Figure 2 As shown, in this embodiment, an infrared laser sensor is arranged on the dial 21 of the water valve 2, so that the opening of the water valve 2 can be determined according to the infrared laser emitted by the infrared laser sensor, and whether the water valve 2 has a physical fault can be determined according to the opening of the water valve 2. Figure 3 As shown, the dial includes scale values ​​from 0 to 100, combined with Figure 4 , the infrared laser sensor is installed on the handle of the dial 21 of the water valve 2, so the distance between the dial 21 of the water valve 2 and the front object can be obtained according to the infrared laser emitted by the infrared laser sensor, and the actual opening degree of the water valve 2 can be calculated according to the obtained distance. In the actual scene, the front object can be the baffle of the air conditioner, that is, the maximum distance and the minimum distance between the dial 21 of the water valve 2 and the baffle are obtained, and then the opening degree of the water valve 2 is calculated.

[0068] like Figure 5 As shown, an embodiment of the present invention further provides a water valve fault management method, which is applied to the water valve fault management system as described in any of the above items. The method specifically includes: steps S101 to S103.

[0069] Step S101, obtaining the communication status between all the water valves and the mainboard controller, and determining the water valves with a communication status of communication connection failure as having a communication failure, and selecting one of the water valves with a communication status of communication connection success as the first target water valve;

[0070] Step S102, sending a first target opening to the first target water valve, and controlling the first target water valve to open and operate;

[0071] Step S103: obtaining the actual opening of the first target water valve through the opening measurement component, and determining whether the first target water valve has a physical fault by combining the first target opening and the actual opening.

[0072] In this embodiment, a communication connection request is first initiated to all water valves to establish a communication connection with the water valves. Here, if there is a water valve with a failed communication connection, it is determined that there is a communication failure, and for a water valve with a successful communication connection, it is determined that the communication is normal. For the water valves with a successful communication connection, one is selected as the target water valve, and the target opening is sent to it so that it operates according to the target opening. During the operation, the actual opening of the target water valve is measured by the opening measurement component, and then combined with the target opening, it is determined whether the current opening of the target water valve is normal, and then it is determined that the target water valve has a physical fault.

[0073] Furthermore, when it is determined that a physical fault exists in the first target water valve, one is selected from the remaining water valves whose communication status is successful communication connection as the second target water valve, and a second target opening is sent to the second target water valve, and the second target water valve is controlled to start and operate, so as to continue to perform physical fault detection on the second target water valve.

[0074] That is to say, when a physical fault is found in the first target water valve, in order to ensure that the air conditioner can continue to maintain overall stable operation, one of the other water valves is selected as the next target water valve (i.e., the second target water valve) to be turned on and operated. Moreover, before selecting the next target water valve, the communication connection detection can be continued for the other water valves to confirm that there is no communication fault in the target water valve to be selected. After the next target water valve is selected, the corresponding target opening (i.e., the second target opening) is sent to it, and the target opening can be the same as or different from the first target opening. Furthermore, after the next target water valve is turned on and operated, the second target water valve is closed.

[0075] This embodiment determines whether there is a communication fault in the water valve based on whether the water valve has established a communication connection, that is, if the mainboard controller and the water valve have not established a communication connection, it indicates that there is a communication fault in the water valve. At the same time, the water valve opening is obtained based on the opening measurement component, so as to determine whether there is a physical fault in the water valve based on the opening, that is, if the water valve opening is abnormal, it indicates that there is a physical fault in the water valve. In addition, this embodiment also sets up a plurality of parallel water valves, so that when any water valve fails, the currently failed water valve can be switched to other normal water valves, thereby ensuring that the air conditioner can operate smoothly and reliably. Therefore, this embodiment can not only accurately identify water valve failures, but also regulate the water valve after identifying the failure to meet the overall operation requirements of the air conditioner.

[0076] It is understandable that the water valve fault management method provided in this embodiment can be the mainboard controller in the water valve fault management system. Of course, in other embodiments, other control entities can also be used to implement the water valve fault management method. It is also understandable that the water valve described in this embodiment is equipped with multiple sensors in addition to the water valve structure itself, such as temperature sensors, flow sensors, etc., so that corresponding data can be collected through these sensors, and the water valve returns the collected data to the mainboard controller.

[0077] In one embodiment, obtaining the actual opening of the first target water valve through the opening measurement component, and judging whether the first target water valve has a physical fault in combination with the first target opening and the actual opening, includes:

[0078] The infrared laser sensor emits an infrared laser and obtains a first distance between the infrared laser and a return point; wherein the return point is a position where the infrared laser returns after encountering an object in front after being emitted;

[0079] The second shortest distance between the front object and the issuing point is obtained, and the actual opening is calculated according to the following formula:

[0080] A = k(L / 2-r);

[0081] Among them, A represents the actual opening, k represents the preset coefficient, L represents the first distance, and r represents the second distance.

[0082] In this embodiment, since the infrared laser sensor is installed on the dial of the water valve, the distance between the water valve dial and the object in front can be obtained according to the infrared laser emitted by the infrared laser sensor, and the actual opening of the water valve can be calculated according to the obtained distance.

[0083] In an actual scenario, the front object may be a baffle of an air conditioner, that is, the maximum distance and the minimum distance between the water valve dial and the baffle are obtained, and then the opening of the water valve is calculated.

[0084] In one embodiment, the obtaining the actual opening of the first target water valve by the opening measurement component, and judging whether the first target water valve has a physical fault in combination with the first target opening and the actual opening, further includes:

[0085] Calculating an opening difference between the first target opening and the actual opening, and determining whether the opening difference is within a preset difference range;

[0086] If the opening difference is within a preset difference range, it is determined that the first target water valve has no physical fault;

[0087] If the opening difference is not within the preset difference range, it is determined that the first target water valve has a physical fault.

[0088] In this embodiment, when judging whether the target water valve has a physical fault in combination with the target opening and the actual opening, the difference between the target opening and the actual opening is first calculated, and then the difference is compared with a preset difference range. If the difference is within the difference range, it indicates that the actual opening of the target water valve is not much different from the target opening, and further indicates that the target water valve is in a normal operating state. If the difference exceeds the difference range, it indicates that the actual opening of the target water valve is significantly different from the target opening, and further indicates that the current operating state of the target water valve is not as expected, and there may be a physical fault, such as a foreign body blockage, etc.

[0089] In one embodiment, the step of obtaining the communication status between all the water valves and the mainboard controller, determining the water valves with a communication status of failed communication connection as having a communication failure, and selecting one of the water valves with a communication status of successful communication connection as the first target water valve includes:

[0090] Continuously sending communication signals to each of the water valves, and determining whether a feedback signal from the water valve is received within a preset feedback time;

[0091] If the feedback signal from the water valve is received within the preset feedback time, it is determined that the communication connection is successful;

[0092] If the feedback signal of the water valve is not received within the preset feedback time, it is determined that the communication connection has failed, and it is determined that the water valve with the failed communication connection has a communication fault.

[0093] In this embodiment, when determining whether a communication failure occurs in the water valve, a method is adopted to continuously send a signal to the water valve so that the water valve responds and gives feedback within a specified time. If the water valve fails to respond and gives feedback within the specified time, it is determined that there is a communication failure, and if the water valve responds and gives feedback within the specified time, it is determined that the communication is normal.

[0094] In one embodiment, the step of obtaining the communication status between all the water valves and the mainboard controller, determining the water valves with a communication status of failed communication connection as having a communication failure, and selecting one of the water valves with a communication status of successful communication connection as the first target water valve, further includes:

[0095] Obtaining the operating time of the water valves with successful communication connection, and comparing the operating time of each water valve with the preset operating time to obtain a comparison result;

[0096] According to the comparison result, a water valve whose operating time is lower than a preset operating time is selected as the first target water valve.

[0097] In this embodiment, after the water valve communication connection is successful, the target water valve is selected according to the operation time of each water valve, that is, the water valve with an operation time lower than the preset operation time is used as the target water valve, and if there are multiple water valves with an operation time lower than the preset operation time, the operation time between the water valves can be compared, and the water valve with the shortest operation time can be selected as the target water valve. In this embodiment, by selecting the target water valve according to the operation time, it can be ensured that the water valve will not be stuck due to long-term inaction, and at the same time, if the water valve is stuck, the problem can be discovered in time.

[0098] In addition, when the number of water valves is small, the target water valve can be selected based on the difference in operating time between the water valves, so as to avoid a certain water valve working for a long time while other water valves are idle for a long time, resulting in a waste of resources. For example, if there are two water valves with successful communication connection, the operating time of the two water valves is obtained, and then it is determined whether the operating time difference of the two water valves exceeds 24 hours. If it exceeds 24 hours, the water valve with the shorter operating time is selected for operation. If it does not exceed 24 hours, one of the water valves can be randomly selected for operation.

[0099] In one embodiment, the water valve fault management method further includes:

[0100] During the operation of the first target water valve, continuously sending a communication signal to the first target water valve, and judging whether a communication failure occurs during the operation of the first target water valve based on the communication signal;

[0101] If it is determined that a communication failure occurs in the operation of the first target water valve, the current opening of the first target water valve is acquired, and based on the current opening, it is determined whether the first target water valve has a physical failure.

[0102] In this embodiment, when the first target water valve is in operation, the communication connection fault detection is continued for the first target water valve to avoid communication interruption during operation. If communication interruption occurs during operation, it is continued to determine whether a physical fault occurs. Here, if no physical fault occurs, the first target water valve can continue to operate, and if a physical fault occurs, its opening is adjusted to the minimum to avoid uncontrollable situations.

[0103] In one embodiment, the water valve fault management method further includes:

[0104] When there is a communication failure in the water valve, an alarm is issued according to a first fault level;

[0105] When the water valve has a physical fault and the number of water valves with the physical fault is within a preset number range, an alarm is issued according to a second fault level;

[0106] When the water valve has a physical fault and the number of water valves with the physical fault exceeds a preset number range, an alarm is issued according to a third fault level;

[0107] The alarm levels of the first fault level, the second fault level and the third fault level increase in sequence.

[0108] This embodiment displays different fault types by setting different levels of alarms. For example, different alarm levels are set for communication faults and physical faults. Furthermore, different alarm levels can be set for the number of communication faults and the number of physical faults. For example, when a water valve has a communication fault, the alarm of the first fault level is set to a constant red light, when a small number of water valves have physical faults, the alarm of the second fault level is set to a slow flashing red light, and when a large number of water valves have physical faults, the alarm of the third fault level is set to a fast flashing red light.

[0109] In a practical application scenario, combined with Figure 6 , the embodiment of the present invention is explained by taking two water valves arranged in parallel (hereinafter referred to as water valve 1 and water valve 2) as an example. First, a communication connection is established with the two water valves. If the communication connection fails, it indicates that there is a communication failure. After the communication connection is successful, the operating time of the two water valves and the operating time difference between the two are judged. If the operating time difference is too large (for example, 24 hours), the water valve with a short operating time is selected as the target water valve. For example, if the operating time of water valve 1 is short, water valve 1 is used as the target water valve. Then, the target opening is sent to the target water valve and the operation is started. During the operation, infrared ranging is performed by an infrared laser sensor to obtain the distance L from the infrared laser to the baffle and the shortest distance r between the baffle and the water valve dial. Then, the actual opening of the target water valve is calculated according to the aforementioned opening calculation formula. Then, the difference between the actual opening and the target opening is compared with the preset difference range. When the difference between the actual opening and the target opening is within the preset difference range, it indicates that the target water valve has no physical fault, so it can continue to operate normally. When the difference between the actual opening and the target opening is not within the preset difference range, it indicates that the target water valve has a physical fault. At this time, it is detected whether there is a communication fault in water valve 2. If there is no communication fault, it is switched to water valve 2 for operation. Of course, if there is also a fault in water valve 2, it is not necessary to switch to water valve 2. In addition, during the operation of the target water valve, if there is a communication interruption, it can be determined whether there is a communication fault or a physical fault in combination with the water valve opening. Through the above process, it is possible to accurately and timely identify whether the water valve has a fault and the type of fault, and the reliability of the overall operation of the air conditioner can also be ensured by switching the water valve.
