[0037] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the protection scope of the application.

[0038] It should be noted that in the embodiments of the present application, the words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design presented as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more advantageous or superior to other embodiments or design solutions. Rather, the use of the words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0039] In order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", etc. are used to distinguish the same or similar items with basically the same function and role. Those skilled in the art can understand that the words "first", "second", etc. are not intended to limit the quantity and execution order.

[0040] Before the device operation and maintenance method provided by the present application is described in detail, the application scenarios and implementation environments involved in the present application are briefly introduced.

[0041] First, the application scenarios involved in the present application are briefly introduced.

[0042] As described in the background, with the development of technologies such as artificial intelligence and cloud computing, the development of data centers is promoted. As an infrastructure, a data center can store and compute massive data to provide operation and maintenance services to different systems, especially systems and devices involving professional knowledge (such as electrical, heating and ventilation, and management professional knowledge) in the operation and maintenance process.

[0043] Because the system to be operated and maintained is relatively complex, it is usually necessary to abstract the operation and maintenance rules related to operation and maintenance specifications and regulations into computer code language during the development stage. However, it is difficult to abstract the operation and maintenance rules related to professional knowledge or expert experience into computer code language.

[0044] At the same time, with the development of large language model technology, a large language model can receive and understand natural language and answer user questions. However, the large language model also needs to rely on professional knowledge to answer questions. The training corpus accepted by a general large language model is too generalized and rarely carries domain professional knowledge, so it is difficult to make accurate replies when facing professional problems.

[0045] In some embodiments, the domain knowledge can be extracted into a prompt word based on a retrieval-augmented generation (RAG) technology to input into a large language model.

[0046] But in some systems or devices, usually related to numerical data, and numerical data usually reflects the problems of the system or device at the data level, and large language models can only process text data and are not good at processing numerical data and other complex data, and it is difficult to answer user questions and operate and maintain the system or device according to numerical data and operation and maintenance rules. Especially for systems (such as air conditioning systems) or devices (such as temperature regulation devices) involving complex data, it is difficult to extract deep information from massive data, resulting in insufficient understanding and computing ability of large language models for complex data, and the inability to provide intelligent operation and maintenance suggestions.

[0047] To solve the above problems, the embodiment of the present application provides a device operation and maintenance method. First, the problem to be processed of the temperature regulation device, the device operation parameter and the device operation and maintenance rule are obtained, wherein the device operation and maintenance rule includes: the device operation index, the operation parameter range corresponding to the device operation index when the temperature regulation device is in different operation states, and the operation and maintenance strategy of the temperature regulation device in different operation states. Then, according to the problem to be processed and the device operation and maintenance rule, the target operation and maintenance index and the target operation parameter range corresponding to the target operation and maintenance index are determined. Then, according to the device operation parameter, the target operation parameter range and the device operation and maintenance rule, the operation state of the temperature regulation device is determined. Then, according to the operation state and the device operation and maintenance rule, the target operation and maintenance strategy of the temperature regulation device is determined.

[0048] As can be seen from the above, the present application not only obtains the problem to be processed and the device operation and maintenance rule, but also obtains the device operation parameter. The device operation parameter can fully reflect the device operation state of the temperature regulation device. The present application determines the target operation and maintenance index according to the problem to be processed, that is, the operation and maintenance index related to the problem to be processed. And the operation parameter range corresponding to the target operation and maintenance index is retrieved from the device operation and maintenance rule, so that the operation state of the temperature regulation device can be determined according to the device operation parameter and the operation parameter range, and the target operation and maintenance strategy is further determined. In the present application, the device operation state can be more accurately determined based on the device operation parameter, and the operation and maintenance strategy can be more professionally output in combination with the device operation rule.

[0049] The implementation environment of the above device operation and maintenance method can be the device operation and maintenance system provided by the embodiment of the present application.

[0050] Figure 1 The structure schematic diagram of the device operation and maintenance system provided by the embodiment of the present application is shown. As shown in Figure 1 The device operation and maintenance system includes: a device operation and maintenance device 101, a data acquisition device 102, a temperature regulation device 103 and an interactive device 104.

[0051] The device operation and maintenance device 101 is in communication connection with the data acquisition device 102 and the interactive device 104, and the data acquisition device 102 is in communication connection with the temperature regulation device 103.

[0052] The temperature regulation device 103 comprises a water chiller, a cooling tower and a water pump.

[0053] The water chiller is a core refrigeration module in the temperature regulation device 103. The cooling tower is a module for heat dissipation in the temperature regulation device 103. The water pump is a module for providing power for water circulation in the temperature regulation device 103.

[0054] The data acquisition device 102 comprises a temperature sensor, a flow sensor and a pressure sensor.

[0055] The data acquisition device 102 can be installed in the temperature regulation device 103 to acquire monitoring data of the temperature regulation device 103, such as chilled water inlet temperature, chilled water outlet temperature, cooling water inlet temperature, cooling water outlet temperature, cooling water flow, chilled water flow, cooling tower inlet temperature, cooling tower outlet temperature, cooling tower cooling water flow, water pump inlet pressure and water pump outlet pressure.

[0056] The data acquisition device 102 can also acquire ambient dry-bulb temperature, ambient wet-bulb temperature and ambient wind speed.

[0057] In some embodiments, the data acquisition device 102 can periodically (such as every 10 minutes, every 1 hour) send monitoring parameters to the device operation and maintenance device.

[0058] The interactive device 104 is used for interaction with a user to acquire questions input by the user and related to the temperature regulation device 103, such as current operation state of the temperature regulation device, current problems of the temperature regulation device, how to maintain the temperature regulation device, or what operation and maintenance suggestions are made for the current operation state of the temperature regulation device.

[0059] The device operation and maintenance device 101 is used for determining a target operation and maintenance strategy according to a to-be-handled question, device operation and maintenance rules and device operation parameters.

[0060] Optionally, the device operation and maintenance device 101 and the interactive device 104 can be two devices independently arranged, or can be integrated in the same device. When the device operation and maintenance device 101 and the interactive device 104 are integrated in the same device, the interactive device 104 can be a communication module of the device operation and maintenance device 101.

[0061] It is easy to understand that when the device operation device 101 and the interaction device 104 are integrated in the same device, the communication mode between the device operation device 101 and the interaction device 104 is the communication between the internal modules of the device. In this case, the communication process between the two is the same as that between the device operation device 101 and the interaction device 104 independent of each other.

[0062] Optionally, the entity device of the device operation device 101 can be a server, a terminal, or other types of electronic devices, and the embodiments of the present application do not limit this.

[0063] Optionally, the terminal can be a device that provides voice and / or data connectivity to users, a handheld device with wireless connection functions, or other processing devices connected to a wireless modem. The wireless terminal can communicate with one or more core networks through a radio access network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or called "cellular" phone) and a computer with a mobile terminal, and can also be a portable, pocket, handheld, built-in computer or vehicle-mounted mobile device that exchanges voice and / or data with a radio access network. For example, a mobile phone, a tablet computer, a notebook computer, a personal digital assistant (PDA).

[0064] Optionally, the server can be one server in a server cluster (composed of multiple servers), a chip in the server, or a system on a chip in the server, or can be implemented through a virtual machine (VM) deployed on a physical machine, and the embodiments of the present application do not limit this.

[0065] Optionally, the device operation device 101 and the interaction device 104 can be two devices independently arranged, or can be integrated in the same device. When the device operation device 101 and the interaction device 104 are integrated in the same device, the interaction device 104 can be a communication module of the device operation device 101.

[0066] It is easy to understand that when the device operation device 101 and the interaction device 104 are integrated in the same device, the communication mode between the device operation device 101 and the interaction device 104 is the communication between the internal modules of the device. In this case, the communication process between the two is the same as that between the device operation device 101 and the interaction device 104 independent of each other.

[0067] For ease of understanding, the device operation device 101 and the interaction device 104 are independent of each other in the embodiments of the present application.

[0068] The device operation and maintenance device in the device operation and maintenance system comprises Figure 2 The elements included. Below, taking Figure 2 The communication device shown as an example, the hardware structure of the device operation and maintenance device is introduced.

[0069] Figure 2 As shown in the hardware structure schematic diagram of a communication device provided by the embodiment of the application. The communication device comprises a processor 21, a memory 22, a communication interface 23, and a bus 24. The processor 21, the memory 22, and the communication interface 23 can be connected through the bus 24.

[0070] The processor 21 is the control center of the communication device, and can be one processor or a general term of multiple processing elements. For example, the processor 21 can be a general central processing unit (CPU), or other general-purpose processors, etc. Among them, the general-purpose processor can be a microprocessor or any conventional processor, etc.

[0071] As an embodiment, the processor 21 can comprise one or more CPUs, for example Figure 2 The CPU 0 and the CPU 1 shown in the above.

[0072] The memory 22 can be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a magnetic disk storage medium or other magnetic storage device, or any other medium capable of carrying or storing desired program code in the form of instructions or data structures and capable of being accessed by a computer, but not limited to this.

[0073] In a possible implementation manner, the memory 22 can exist independently of the processor 21, and the memory 22 can be connected with the processor 21 through the bus 24, and is used for storing instructions or program codes. When the processor 21 invokes and executes the instructions or program codes stored in the memory 22, the device operation and maintenance method provided by the embodiments of the application can be implemented.

[0074] In the embodiments of the application, for the communication device, the software programs stored in the memory 22 are different, so the functions implemented by the communication device are different. The functions performed by each device will be described in combination with the flowchart below.

[0075] In another possible implementation, the memory 22 can also be integrated with the processor 21.

[0076] The communication interface 23 is configured to connect the communication device with other devices through a communication network, which can be an Ethernet, a wireless access network, a wireless local area network (WLAN), or the like. The communication interface 23 can include a receiving unit configured to receive data, and a sending unit configured to send data.

[0077] The bus 24 can be an industry standard architecture (ISA) bus, a peripheral component interconnect (PCI) bus, an extended industry standard architecture (EISA) bus, or the like. The bus can be divided into an address bus, a data bus, a control bus, and the like. For ease of representation, Figure 2 In the drawings, only one thick line is used to represent the bus, but it does not mean that there is only one bus or only one type of bus.

[0078] It should be noted that Figure 2 The structure shown in the drawings does not constitute a limitation on the communication device, except Figure 2 In addition to the components shown, the communication device can include more or fewer components than shown, or combine some components, or different arrangement of components.

[0079] The device operation and maintenance method provided by the embodiments of the present application will be described in detail below with reference to the drawings.

[0080] The device operation and maintenance method provided by the embodiments of the present application is applied to Figure 1 The device operation and maintenance device 101 in the device operation and maintenance system shown in the drawings, such as Figure 3 The device operation and maintenance method provided by the embodiments of the present application includes:

[0081] S301, obtaining a to-be-handled problem of a temperature regulation device, device operation parameters, and device operation and maintenance rules.

[0082] The device operation and maintenance rules include: device operation indexes, a range of operation parameters corresponding to the device operation indexes when the temperature regulation device is in different operation states, and operation and maintenance strategies of the temperature regulation device in different operation states.

[0083] The to-be-handled problem is a problem related to the temperature regulation device raised by a user.

[0084] The device operation parameters include monitoring parameters and performance parameters.

[0085] The monitoring parameters include: chilled water inlet temperature, chilled water outlet temperature, cooling water inlet temperature, cooling water outlet temperature, cooling water flow rate, chilled water flow rate, chiller power, cooling tower inlet temperature, cooling tower outlet temperature, cooling tower cooling water flow rate, cooling tower fan power, water pump inlet pressure, water pump outlet pressure, water pump electric power, water pump flow rate, ambient dry-bulb temperature, ambient wet-bulb temperature, and ambient wind speed.

[0086] The performance parameters include: chiller refrigeration capacity, chiller coefficient of performance (COP), condenser heat dissipation, cooling tower heat dissipation, cooling tower approximation degree, cooling tower efficiency, water pump efficiency, and water pump head.

[0087] The device operation and maintenance device can obtain the to-be-processed problem from the interactive device. The device operation and maintenance device can obtain the monitoring parameters from the data acquisition device, and further determine the performance parameters.

[0088] The device operation and maintenance rules can be pre-stored in the device operation and maintenance device, or obtained from other platforms or systems.

[0089] In some embodiments, the device operation and maintenance device obtains the to-be-processed problem, specifically including:

[0090] First, the user question is obtained, the user question is divided into clauses according to symbols (including: comma, period, colon, and exclamation mark), and the clauses are processed by word segmentation based on the forward maximum matching algorithm. Then, the stop words without actual meaning are removed based on the stop list to obtain the to-be-processed problem.

[0091] Common stop words include: "of", "get", "place", "in", and "have".

[0092] S302, determining a target operation and maintenance index and a target operation parameter range corresponding to the target operation and maintenance index according to the to-be-processed problem and the device operation and maintenance rules.

[0093] The target operation and maintenance index is determined according to the to-be-processed problem and the device operation and maintenance rules, specifically including:

[0094] S3021, determining a reference operation and maintenance index related to the to-be-processed problem.

[0095] For example, when the to-be-processed problem is "evaluate the state of the chiller", the reference operation and maintenance index at least includes one of the following: chilled water inlet temperature, chilled water outlet temperature, cooling water inlet temperature, cooling water outlet temperature, cooling water flow rate, chilled water flow rate, chiller power, chiller refrigeration capacity, chiller COP, and condenser heat dissipation.

[0096] Yet another example, when the problem to be processed is "what operation and maintenance suggestions are there for the current water pump", the reference operation and maintenance indicators at least include one of the following: water pump inlet pressure, water pump outlet pressure, water pump electric power, water pump flow, water pump efficiency and water pump lift.

[0097] It should be understood that according to the problem to be processed, the reference operation and maintenance indicators involved in the problem to be processed can be determined.

[0098] S3022, according to the reference operation and maintenance indicators, matching target operation and maintenance indicators from the equipment operation and maintenance rules.

[0099] Among them, the similarity between the reference operation and maintenance indicators and the target operation and maintenance indicators is greater than the preset similarity.

[0100] Specifically, the equipment operation and maintenance device adopts an exact search method to compare the reference operation and maintenance indicators with the entity information in the equipment operation and maintenance rules to match the target operation and maintenance rules. The target operation and maintenance rules include: target operation and maintenance indicators, target operation and maintenance indicators corresponding operating parameter range, target operation and maintenance indicators corresponding operating state, and related operation and maintenance strategies.

[0101] S303, according to the equipment operating parameters, the target operating parameter range and the equipment operation and maintenance rules, determining the operating state of the temperature regulation equipment.

[0102] The operating state includes but is not limited to: low load of water chiller, large flow of water chiller, insufficient refrigerating capacity of water chiller, dirty and blocked condenser, aging of water chiller, blocked cooling tower, insufficient air volume of cooling tower, and blocked water pump pipeline.

[0103] It should be understood that the equipment operation and maintenance rules include: the operating parameter range of the equipment operating indicators when the temperature regulation equipment is in different operating states. The equipment operation and maintenance rules can determine whether the equipment operating parameters are out of the target operating parameter range and determine the relationship between the equipment operating parameters and the target operating parameter range (including: the equipment operating parameters are in the target operating parameter range, the equipment operating parameters are less than the minimum value of the target operating parameter range, and the equipment operating parameters are greater than the maximum value of the target operating parameter range) according to the equipment operating parameters and the target operating parameter range, to further determine the operating state of the temperature regulation equipment and / or the operating state of the specific module in the temperature regulation equipment according to the equipment operation and maintenance rules.

[0138] S403. Determine the equipment operating parameters based on the monitoring parameters and performance parameters.

[0139] The equipment operating parameters include at least one of the following: the maximum value of the monitoring parameter, the minimum value of the monitoring parameter, the average value of the monitoring parameter, the maximum value of the performance parameter, the minimum value of the performance parameter, and the average value of the performance parameter.

[0140] The equipment maintenance equipment can perform further calculations on the above monitoring parameters and performance parameters, that is, determine the maximum value, minimum value, and average value of the monitoring parameters, as well as the maximum value, minimum value, and average value of the performance parameters.

[0141] In this embodiment of the application, the equipment maintenance equipment can determine the performance parameters based on the monitoring parameters within a preset time period (such as the first 24 hours), and further determine the equipment operating parameters.

[0142] In practical applications, equipment maintenance equipment not only stores the equipment's operating parameters, but also its corresponding equipment name and the corresponding time.

[0143] In this embodiment, by processing the real-time acquired monitoring parameters, deeper performance parameters of the temperature regulation device are extracted. By combining the monitoring parameters and performance parameters, and more accurately combining them with the equipment operation and maintenance rules, further judgments are made, making the equipment operation and maintenance strategy output by this application more precise.

[0144] In some embodiments, device operation and maintenance rules are represented by an operation and maintenance rule graph. The operation and maintenance rule graph includes multiple nodes, where nodes represent entity information, and edges between any two nodes represent the correspondence between the entity information corresponding to the two nodes. Figure 3 ,like Figure 5 As shown, the equipment operation and maintenance methods also include:

[0145] S501. Extract entity information of equipment operation and maintenance rules.

[0146] The entity information includes: equipment operating indicators, operating status, operating parameter range, and operation and maintenance strategies.

[0147] Extract the entity information of the equipment operation and maintenance rules, specifically including:

[0148] S5011. Perform word segmentation on the equipment operation and maintenance rules, and remove symbols and stop words from the equipment operation and maintenance rules to obtain entity information.

[0149] Punctuation marks include: comma, period, colon, exclamation mark, quotation mark, and special symbols such as asterisk, hash, dash, etc.

[0150] The device operation and maintenance device also unifies the text in the device operation and maintenance rule.

[0151] Specifically, the device operation and maintenance device can use the forward maximum matching algorithm to segment the device operation and maintenance rule.

[0152] The device operation and maintenance device takes the device operation parameter corresponding to the device operation index (i.e. physical quantity name) as the first entity information, and takes the entity information near the first entity information in the device operation and maintenance rule as the second entity information. The relevance of the second entity information to the first entity information is greater than the preset relevance. The device operation and maintenance device takes other entity information in the device operation and maintenance rule as the third entity information.

[0153] It should be understood that the third entity information is the information related to the first entity information and the second entity information in the operation and maintenance rule, but the expression of the third entity information is different from that of the first entity information and the second entity information.

[0154] S502, according to the entity information and the corresponding relationship between the entity information, the operation and maintenance rule graph is constructed.

[0155] The corresponding relationship includes: the corresponding relationship between the device operation index and the operation parameter range, the corresponding relationship between the operation state and the operation parameter range, and the corresponding relationship between the operation state and the operation and maintenance strategy.

[0156] In some embodiments, the device operation and maintenance device constructs a first operation and maintenance rule graph according to the first entity information, the second entity information, and the corresponding relationship between the first entity information and the second entity information, and the corresponding relationship between the second entity information. The device operation and maintenance device constructs a second operation and maintenance rule graph according to the third entity information and the corresponding relationship between the third entity information.

[0157] Specifically, first, the device operation and maintenance rule is obtained. Then, based on the physical information framework graph (i.e. device operation index), the entity information is extracted, and the first operation and maintenance rule graph (i.e. specified structure graph data) is constructed. Based on the natural language framework graph, the entity information is extracted, and the second operation and maintenance rule graph (i.e. non-specified structure graph data) is constructed.

[0158] In this embodiment, the first entity information is the device operation index, and the second entity information includes: operation parameter range, operation state, and operation and maintenance strategy. The third entity information includes: device operation index, operation parameter range, operation state, and operation and maintenance strategy.

[0159] It should be understood that the difference between the first operation and maintenance rule graph and the second operation and maintenance rule graph is that the device operation and maintenance rule can directly retrieve the same target operation and maintenance index as the reference operation and maintenance index expression from the first operation and maintenance rule graph, while the device operation and maintenance device needs to retrieve the similar target operation and maintenance index from the second operation and maintenance rule graph.

[0160] In practical applications, the entity information in the operation and maintenance rule graph is usually vector-represented entity information and is stored in a vector library.

[0161] The device operation and maintenance device can compare the reference operation and maintenance index with the entity information in the operation and maintenance rule graph based on an accurate search method to determine the target operation and maintenance index, and then determine the target operation parameter range corresponding to the target operation and maintenance index, the operation state, and the target operation and maintenance strategy.

[0162] The device operation and maintenance device can also compare the reference operation and maintenance index vector with each operation and maintenance index vector in the vector library to determine the cosine similarity (Cosine Similarity) of the reference operation and maintenance index vector and each operation and maintenance index vector in the vector library, which satisfies the following formula:

[0163]

[0164] Where C is the cosine similarity, A is the reference operation and maintenance index vector, and B is the operation and maintenance index vector in the vector library.

[0165] In the case where the cosine similarity is greater than a preset similarity, the target operation and maintenance index can be determined, and then other contents, i.e., the target operation parameter range, the operation state, and the target operation and maintenance strategy, can be determined.

[0166] In the embodiments of the present application, not only the first operation and maintenance rule graph is constructed, but also the second operation and maintenance rule graph is constructed, the first operation and maintenance rule graph can be accurately searched, so that the operation and maintenance index corresponding to the problem to be processed can be accurately matched, and the second operation and maintenance rule graph can be searched in a fuzzy manner, so that the generalization of the search process is ensured to comprehensively and accurately retrieve the target operation and maintenance rule related to the problem to be processed.

[0167] In some embodiments, the device operation and maintenance method further comprises:

[0168] Inputting the problem to be processed, the device operation parameter, and the target operation and maintenance rule into a large language model to output an answer corresponding to the problem to be processed.

[0169] The answer includes the corresponding relationship between the problem to be processed, the device operation parameter, and the target operation and maintenance rule, and the analysis process of the problem to be processed. The target operation and maintenance rule includes the target operation and maintenance index, the target operation parameter range, the operation state, and the target operation and maintenance strategy.

[0170] In this embodiment, the large language model can be a Unicom Yuanjing large model.

[0171] The large language model can output an answer corresponding to the problem to be processed, such as an operation and maintenance suggestion and a control instruction of the current state, according to the problem to be processed.

[0172] As can be seen from the above, the equipment operation and maintenance device can determine an equipment operation and maintenance strategy by the equipment operation and maintenance method shown in the figure, to perform operation and maintenance on the temperature regulation equipment. Figure 6

[0173] On the one hand, the equipment operation and maintenance rules (for example, air conditioner operation and maintenance specifications, air conditioner operation and maintenance regulations) are obtained, and the equipment operation and maintenance rules are input into the graph data conversion module to extract entity information of the equipment operation and maintenance rules and construct an operation and maintenance rule graph.

[0174] On the other hand, the data acquisition equipment is communicated to obtain monitoring parameters, and the equipment operation parameters are determined according to the monitoring parameters. The equipment operation parameters include monitoring parameters and performance parameters of the temperature regulation equipment.

[0175] After obtaining the problem to be processed, the target operation and maintenance rules are determined based on the retrieval enhancement generation technology, in combination with the problem to be processed and the equipment operation parameters. The target operation and maintenance rules include target operation and maintenance indicators, target operation parameter ranges, operation states, and target operation and maintenance strategies.

[0176] The equipment operation parameters and the target operation and maintenance rules are input into the large language model to output an answer corresponding to the problem to be processed.
