It is necessary to keep up with the pace of the times and realize intelligent control and efficient energy management of HVAC units. However, traditional HVAC units have certain limitations in operation and management. HVAC units from different manufacturers often use different control protocols and interface standards, which brings great difficulties to the integration and management of HVAC systems.

[0003] For example, in an industrial park, HVAC units from multiple manufacturers are used. To manage these devices, there are generally two ways. The first method is to use corresponding software or hardware to control the equipment of each manufacturer, which will result in the coexistence of multiple software or hardware of the same type (all related to HVAC units). This method is simple and direct, but it will complicate management because each device requires a dedicated management system and operator; the second method is to redevelop and debug these devices and management software.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] In order to solve the problems mentioned in the background technology, according to one aspect of an embodiment of the present application, an embodiment of a HVAC unit control method is provided.

[0028] like Figure 1 As shown, the above HVAC unit control method can be applied to Figure 1In the system framework shown. The system framework is a digital base 100 based on script parsing adaptation connection HVAC units, including protocol data 101 of different HVAC units, a script parser 103, and a platform management system 105. The protocol data 101 of different HVAC units is transmitted to the script parser 103 through the network, and the script parser 103 communicates with the platform management system 105 through the network for data transmission. Among them, the network can include various connection types, such as wired, wireless communication links or optical fiber cables.

[0029] The protocol data 101 of different HVAC units can be the protocol data of cross-manufacturer or cross-brand HVAC units in different application scenarios, and the protocol data of each HVAC unit carries a corresponding conversion script. The number of protocol data 101 of different HVAC units can be determined according to the actual situation of the application scenario. Among them, different application scenarios can be actual application scenarios such as residential areas, hospitals, laboratories, industrial parks, etc. The protocol data includes network protocols, electronic control protocols, and point parameter data. The network protocol and the electronic control protocol are necessary protocols for the interconnection of HVAC units. The network protocol realizes mutual communication, and the electronic control protocol realizes the control of the unit. Point parameter data includes but is not limited to outdoor temperature, humidity, and air conditioning preset temperature, etc., which provide a basis for platform system data analysis.

[0030] The script parser 103 is used to parse and analyze the protocol data 101 of different HVAC units to adapt to the management and control of different HVAC units. The script parser 103 includes a rule base and a preset parsing algorithm. The rule base is a database that integrates many common (standard) protocols (such as modbus, bacnet protocol, etc.) in advance, also known as a protocol library, which can more quickly match the data protocols from various HVAC equipment and convert them into target data protocols. The preset parsing algorithm is an alternative solution. If there is no corresponding matching protocol data in the rule base, the received protocol data can be converted into target protocol data through the preset parsing algorithm.

[0031] The platform management system 105 includes data integration analysis and intelligent control decision-making. The received protocol data is synchronized to the platform management system 105 through the script parser 103. The platform collects point data for a period of time (such as outdoor temperature, humidity and current air-conditioning setting temperature, etc.). The first step to obtain data is to clean the data and improve the data quality. The data is then stored to achieve open sharing of data across systems. In addition, the collected data is analyzed to discover the patterns, trends and correlations hidden behind the data. This is very important for the subsequent platform system to give optimization strategies through intelligent control decisions.

[0032] It should be noted that the HVAC unit control method provided in the embodiment of the present application is generally executed by a script parser, and accordingly, the HVAC unit control device is generally set in the script parser. And it should be understood that, Figure 1 The number of protocol data 101, script parser 103, and platform management system 105 of different HVAC units is only illustrative. According to the implementation requirements, there can be any number of protocol data 101, script parser 103, and platform management system 105 of different HVAC units.

[0033] like Figure 2 As shown, Figure 2 A flow chart of a HVAC unit control method provided by an embodiment of the present invention. Taking the HVAC unit control method executed by a script parser as an example, a HVAC unit control method includes the following steps:

[0034] Step S202, obtaining HVAC unit protocol data to be processed.

[0035] In this embodiment, the provided HVAC unit control method is applicable to cross-manufacturer or cross-brand HVAC unit communication control scenarios, which can be practical scenarios such as residential areas, hospitals, laboratories, industrial parks, etc. that require communication control of cross-manufacturer HVAC units, and of course, can also be communication control scenarios for HVAC units of different brands from the same manufacturer. During the HVAC unit control process, the control system of the HVAC unit can monitor the protocol data of the HVAC units of each manufacturer involved in all links in real time, including real-time data reading, analysis, judgment, control and other processes.

[0036] In this embodiment, the above-mentioned HVAC unit protocol data to be processed may include protocol data corresponding to HVAC units of different manufacturers or brands that need to be controlled for communication in a certain scenario; for example, in a community, each household may use a different brand of HVAC, and the interface protocol data used by each brand is different, some are protocol data 1, some are protocol data 2, and some are protocol data 3. The number of the above-mentioned HVAC unit protocol data to be processed can be single or multiple. For example, if there is one HVAC unit to be controlled, the acquired HVAC unit protocol data to be processed can be one. Of course, when 10 different HVAC units need to be controlled, the acquired HVAC unit protocol data to be processed is 10. In this embodiment, the number of HVAC unit protocol data to be processed can be determined according to the actual number of HVAC units to be controlled, and the number of HVAC unit protocol data to be processed is not limited here. The above-mentioned HVAC units may include various HVAC air conditioners, heaters and other heating equipment.

[0037] Among them, Figure 3As shown in the figure, the protocol data includes network protocol, electric control protocol and point parameter data. Network protocol and electric control protocol are necessary protocols for HVAC unit interconnection. Network protocol realizes mutual communication, while electric control protocol realizes control of the unit. Point parameter data includes but is not limited to outdoor temperature, humidity and air conditioning preset temperature, etc., which provides a basis for platform system data analysis.

[0038] The above-mentioned HVAC unit protocol data to be processed all carry corresponding conversion scripts for converting the HVAC unit protocol data to be processed. The conversion script contains many conversion functions, mainly the conversion function of certain protocol data to standard protocol data. Among them, the conversion function can be customized and can be selected according to different protocol data.

[0039] In some embodiments, when it is necessary to communicate and control multiple HVAC units of different manufacturers or brands in a certain scenario, the protocol data corresponding to the HVAC unit can be obtained first. The HVAC unit protocol data to be processed can be the protocol data sent by the HVAC unit in real time, or it can be the pre-stored HVAC unit protocol data.

[0040] Step S204, detecting whether there is integrated protocol data matching the HVAC unit protocol data to be processed in the preset rule base; the preset rule base is pre-integrated with a plurality of integrated protocol data.

[0041] In some embodiments, the preset rule library integrates a database of many common (standard) protocols (such as modbus, bacnet protocols, etc.) in advance, also known as a protocol library, which can more quickly match the protocol data from each HVAC device and convert it into target protocol data. The above-mentioned integrated protocol data is the protocol data pre-integrated and stored in the above-mentioned preset rule library. The number of integrated protocol data can be multiple. When it is necessary to control many HVAC devices, the corresponding protocol data can be integrated in the preset rule library to facilitate reading and control during communication control.

[0042] In some embodiments, after the HVAC unit protocol data to be processed is obtained, the HVAC unit protocol data to be processed can be compared with the multiple integrated protocol data integrated in the preset rule library. According to the comparison result, it is determined whether there is protocol data matching the HVAC unit protocol data to be processed in the preset rule library. If the protocol to be processed matches a certain integrated protocol data in the preset rule library, it means that there is integrated protocol data matching the HVAC unit protocol data to be processed in the preset rule library. If the HVAC unit protocol data to be processed does not match any of the integrated protocol data in the preset rule library, it means that there is no integrated protocol data matching it in the preset rule library. When there is no integrated protocol data matching the HVAC unit protocol data to be processed in the preset rule library, it means that the HVAC unit corresponding to the HVAC unit protocol data to be processed is a new device with a different access protocol launched by a certain manufacturer, and the corresponding protocol standard is not integrated in the rule library.

[0043] Step S206: If there is integrated protocol data matching the HVAC unit protocol data to be processed in the preset rule base, the HVAC unit protocol data to be processed is converted into target protocol data.

[0044] In some embodiments, the preset protocol rules are pre-set protocol conversion rules for converting between protocol data. Figure 4 As shown, the preset protocol rules can be used to execute: the protocol intercommunication process of converting A protocol data into standard protocol data, and then converting the standard protocol into B data protocol. Among them, A protocol data can refer to the HVAC unit protocol data to be processed, B protocol data can be the target protocol data, and standard protocol data can refer to the general protocol conversion standard for converting between the HVAC unit protocol data to be processed and the target protocol data.

[0045] In some embodiments, when it is determined that integrated protocol data matching the HVAC unit protocol data to be processed exists in the preset rule base, the HVAC unit protocol data to be processed can be converted into corresponding target protocol data through the preset protocol rules.

[0046] Step S208, sending the target protocol data to the target HVAC unit.

[0047] Among them, the above-mentioned target HVAC unit may be the HVAC unit corresponding to the HVAC unit protocol data to be processed.

[0048] In this embodiment, after the HVAC unit protocol data to be processed is converted into target protocol data, the target protocol data can be sent to the corresponding target HVAC unit to facilitate communication control of the target HVAC unit.

[0049] In an embodiment of the present invention, by obtaining the HVAC unit protocol data to be processed and detecting whether there is integrated protocol data matching the HVAC unit protocol data to be processed in the preset rule base, if there is, the HVAC unit protocol data to be processed is converted into target protocol data based on the preset protocol rules and then sent to the target HVAC unit. This method can search and match protocol data in a rule base that integrates a large amount of existing protocol data, and convert the received protocol data through preset protocol rules to achieve communication and interoperability between HVAC units across manufacturers or brands, thereby improving the adaptability of the equipment; at the same time, a single system or software can be used to centrally control and manage HVAC units across manufacturers or brands, reducing the cost of specialized management systems and operators, thereby reducing the management cost of HVAC units.

[0050] In an optional embodiment, after step S204, the method further includes:

[0051] If there is no integrated protocol data matching the HVAC unit protocol data to be processed in the preset rule base, the HVAC unit protocol data to be processed is parsed by a preset parsing algorithm and a preset conversion script to obtain a parsing result;

[0052] Generate new protocol rules according to the analysis results;

[0053] After storing the new protocol rules and the HVAC unit protocol data to be processed in the preset rule base, it is again detected whether there is integrated protocol data matching the HVAC unit protocol data to be processed in the preset rule base.

[0054] In this embodiment, the preset parsing algorithm is used to parse the HVAC unit protocol data to be processed. The preset parsing algorithm generally includes lexical analysis and grammatical analysis, wherein the lexical analysis includes a finite automaton algorithm that can identify words in the script, and the grammatical analysis includes a recursive descent analysis method, an operator finite analysis method, etc., and the grammatical analysis is performed by constructing a grammatical parsing tree. In short, the preset parsing algorithm can convert the script code into an internal representation that can be understood by the computer. The preset parsing algorithm is an alternative solution. If there is no matching integrated protocol data in the rule base, the received protocol data can be converted into the target protocol data through the preset parsing algorithm.

[0055] The above-mentioned preset conversion script is a pre-set conversion script, and is a conversion script carried by each protocol data itself, which can convert the corresponding protocol data. Each protocol data corresponds to a conversion script. Among them, the conversion script includes many conversion functions, mainly the conversion function of certain protocol data to standard protocol data.

[0056] The above new protocol rules are new protocol rules set for new protocol data. That is, when the HVAC unit protocol data to be processed does not find matching integrated protocol data in the preset rule library, it means that the HVAC unit protocol data to be processed is new protocol data. At this time, new protocol rules need to be set for the new protocol data.

[0057] In this embodiment, when there is no integrated protocol data matching the HVAC unit protocol data to be processed in the preset rule base, it means that the HVAC unit protocol data to be processed is new protocol data, that is, the HVAC unit protocol data to be processed is not stored and recorded in the preset rule base, and the corresponding protocol rules are not integrated in the preset rule base. This means that the HVAC equipment corresponding to the HVAC unit protocol data to be processed may be a new device with a different access protocol launched by a certain manufacturer, or a device from another new manufacturer. At this time, it is necessary to parse and analyze the HVAC unit protocol data to be processed and generate new protocol rules. After storing the new protocol rules and the HVAC unit protocol data to be processed in the preset rule base, it is again detected whether there is integrated protocol data matching the HVAC unit protocol data to be processed in the preset rule base. In this way, when the protocol data is obtained next time, the corresponding protocol data can be directly found from the preset rule base, and the corresponding target HVAC unit can be controlled and managed for communication.

[0058] In this embodiment, new protocol rules are generated after parsing the new HVAC unit protocol data to be processed, and the new HVAC unit protocol data to be processed and the protocol rules are archived and stored in the warehouse to facilitate centralized control and management, thereby improving the adaptability of HVAC units across manufacturers or brands. At the same time, archiving in the existing rule library and managing on the existing management platform can reduce management costs.

[0059] In an optional embodiment, after step S202, the method further includes:

[0060] Identify the protocol data type of the HVAC unit protocol data to be processed;

[0061] Determine whether there is a same protocol data type in the preset rule base;

[0062] If the same protocol data type exists in the preset rule base, detecting whether there is integrated protocol data matching the HVAC unit protocol data to be processed in the preset rule base based on the same protocol data type;

[0063] If the same protocol data type does not exist in the preset rule base, the HVAC unit protocol data to be processed is parsed using the preset parsing algorithm to obtain the parsing result.

[0064] In this embodiment, the above-mentioned protocol data types include CAN network communication protocol, Modbus protocol, 485 communication protocol, BMS building protocol, etc. Among them, different protocols have different characteristics, such as protocol header, data format or encoding method, etc. Protocol header: Many protocols contain a specific header at the beginning of the data packet to identify the protocol type and version. Data format: Different protocols have different data formats, for example, JSON, XML, HTTP, etc. have their own unique formats. Encoding method: The encoding method of data is also an important feature for identifying the protocol, such as UTF-8, ASCII, etc.

[0065] Specifically, first read the protocol data and preliminarily filter out irrelevant blank characters, comments, etc., then perform feature detection, that is, check the header of the data packet to identify the specific protocol type. After identifying the protocol data type of the HVAC unit protocol data to be processed, compare it with the protocol data type integrated in the preset rule library to determine whether there is the same protocol data type in the preset rule library. If the preset rule library has the same protocol data type, it means that the corresponding protocol data type has been integrated in the preset rule library, and it is necessary to execute step S204 to determine whether the corresponding protocol data type module matches the protocol data already integrated in the preset rule library.

[0066] In some examples, when the preset rule base does not have the same protocol data type, it means that the preset rule base does not have the corresponding protocol data type integrated, and the HVAC unit may be from another manufacturer or a new brand of equipment. At this time, it is necessary to execute step S206 to parse the HVAC unit protocol data to be processed through a preset parsing algorithm to obtain a parsing result to complete the addition of new protocol data.

[0067] In this embodiment, the protocol data type is first compared and judged. After the type of HVAC unit protocol data to be processed is determined, it is only necessary to match the protocol data under the protocol data type. There is no need to match all the protocol data in the preset rule library. This can greatly improve the matching time of the protocol data and improve the matching speed of the protocol data.

[0068] In an optional embodiment, the above step 206 specifically includes:

[0069] Converting the HVAC unit protocol data to be processed into standard protocol data according to preset protocol rules;

[0070] The standard protocol data is converted into target protocol data according to the protocol data type of the target HVAC unit to be sent.

[0071] In this embodiment, the above-mentioned target HVAC unit is a HVAC unit that needs to be controlled by communication. After matching the corresponding integrated protocol data in the preset rule base, the HVAC unit protocol data to be processed can be converted into standard protocol data according to the preset protocol rules and protocol data types, and then the standard protocol data is converted into the target protocol data of the corresponding target HVAC unit, so as to facilitate communication control of the target HVAC unit through the target protocol data. In this way, the target protocol data can be directly converted according to the preset protocol rules and protocol data types, which can improve the conversion speed of the target protocol data. This will improve the adaptability and efficiency of the HVAC unit.

[0072] In an optional embodiment, the HVAC unit protocol data to be processed is parsed by a preset parsing algorithm and a preset conversion script to obtain a parsing result, which specifically includes:

[0073] Parsing the HVAC unit protocol data to be processed according to the protocol data type of the HVAC unit protocol data to be processed by the preset parsing algorithm to obtain parsed protocol data;

[0074] Converting the parsed protocol data into new standard protocol data by using the preset conversion script;

[0075] The new standard protocol data is converted into new target protocol data.

[0076] In this embodiment, after determining that there is no corresponding protocol data type in the preset rule library, or no corresponding integrated protocol data is matched, the HVAC unit protocol data to be processed can be analyzed by the preset parsing algorithm and the identified protocol data type, and then converted into new standard protocol data by the preset conversion script, and then the new standard protocol data is converted into new target protocol data. This facilitates the generation of protocol rules for new protocol data, realizes the inverse operation of protocol conversion, and facilitates the control of new HVAC units according to the new protocol rules in the later stage, so as to improve the adaptability of HVAC units and reduce management costs.

[0077] In an optional embodiment, the above-mentioned identification of the protocol data type of the HVAC unit protocol data to be processed specifically includes:

[0078] Extracting protocol data features of the HVAC unit protocol data to be processed;

[0079] The protocol data feature is compared with a preset protocol data type feature, and the protocol data type of the HVAC unit protocol data to be processed is determined according to the comparison result.

[0080] In this embodiment, in the process of processing the HVAC unit protocol data, the protocol data features of the HVAC unit protocol data to be processed can be first extracted, such as extracting the features of the protocol header in the HVAC unit protocol data to be processed, because many protocols contain a specific header at the beginning of the data packet, which is used to identify the protocol type and version. As long as the features of the protocol header are identified, the protocol data type of the corresponding HVAC unit protocol data to be processed can be known. Of course, in many known protocol data, the corresponding protocol data type features are also known. After obtaining the protocol data type features of the HVAC unit protocol data to be processed, the protocol data type of the HVAC unit protocol data to be processed can be obtained after comparison with the known protocol data type features. In this way, comparison with the preset protocol data type features can quickly identify the protocol data category of the HVAC unit protocol data to be processed, thereby improving the adaptability of the protocol data of different HVAC units, and at the same time improving the centralized control management cost of different HVAC units.

[0081] In an optional embodiment, before the above step S202, the above method further includes:

[0082] Creating the preset rule base;

[0083] Creating the preset parsing algorithm, wherein the preset parsing algorithm includes a word analysis algorithm and a grammar analysis algorithm for parsing the HVAC unit protocol data to be processed; and / or

[0084] The preset conversion script is created, wherein the preset conversion script includes a plurality of protocol data conversion functions for converting the HVAC unit protocol data to be processed.

[0085] In this embodiment, a preset parsing algorithm, a preset conversion script, and a preset rule base are first created. The protocol data corresponding to the HVAC unit that needs to be centrally controlled and managed is parsed and converted to determine the protocol data type, convert the standard protocol data, and generate preset protocol rules. Then, the mapping relationship between the protocol data type, standard protocol data, and preset protocol rules corresponding to the protocol data of the HVAC unit is integrated in a database, and then a preset rule base is obtained, so that when communicating and controlling with the HVAC unit, it can quickly identify the match, and then communicate with the target HVAC unit, so as to achieve the centralized control adaptability of cross-manufacturer or cross-brand HVAC units and reduce the centralized management cost.

[0086] According to another aspect of the embodiment of the present application, Figure 5 As shown, corresponding to the HVAC unit control method in the above embodiment, this embodiment provides a HVAC unit control device 500, the device comprising:

[0087] An acquisition module 501 is used to acquire HVAC unit protocol data to be processed;

[0088] The detection module 503 is used to detect whether there is integrated protocol data matching the HVAC unit protocol data to be processed in the preset rule base; the preset rule base is pre-integrated with a plurality of integrated protocol data;

[0090] The sending module 507 is used to send the target protocol data to the target HVAC unit.

[0091] It should be noted that the acquisition module 501 in this embodiment can be used to execute step S202 in the embodiment of the present application, the detection module 503 in this embodiment can be used to execute step S204 in the embodiment of the present application, the conversion module 505 in this embodiment can be used to execute step S206 in the embodiment of the present application, and the sending module 507 in this embodiment can be used to execute step S208 in the embodiment of the present application.

[0092] In an embodiment of the present invention, by obtaining the HVAC unit protocol data to be processed and detecting whether there is integrated protocol data matching the HVAC unit protocol data to be processed in the preset rule base, if there is, the HVAC unit protocol data to be processed is converted into target protocol data based on the preset protocol rules and then sent to the target HVAC unit. This method can search and match protocol data in a rule base that integrates a large amount of existing protocol data, and convert the received protocol data through preset protocol rules to achieve communication and interoperability between HVAC units across manufacturers or brands, thereby improving the adaptability of the equipment; at the same time, a single system or software can be used to centrally control and manage HVAC units across manufacturers or brands, reducing the cost of specialized management systems and operators, thereby reducing the management cost of HVAC units.

[0093] Optionally, the device also includes: a parsing module, which is used to parse the HVAC unit protocol data to be processed by using a preset parsing algorithm and a preset conversion script to obtain a parsing result if there is no integrated protocol data matching the HVAC unit protocol data to be processed in the preset rule base; a generation module, which is used to generate new protocol rules according to the parsing result; and a storage module, which is used to store the new protocol rules and the HVAC unit protocol data to be processed into the preset rule base, and then to detect again whether there is integrated protocol data matching the HVAC unit protocol data to be processed in the preset rule base.

[0094] In this embodiment, new protocol rules are generated after parsing the new HVAC unit protocol data to be processed, and the new HVAC unit protocol data to be processed and the protocol rules are archived and stored in the warehouse to facilitate centralized control and management, thereby improving the adaptability of HVAC units across manufacturers or brands. At the same time, archiving in the existing rule library and managing on the existing management platform can reduce management costs.

[0095] Optionally, the device also includes: an identification module, used to identify the protocol data type of the HVAC unit protocol data to be processed; a judgment module, used to judge whether the same protocol data type exists in the preset rule base; a first execution module, used to detect whether there is integrated protocol data matching the HVAC unit protocol data to be processed in the preset rule base based on the same protocol data type if the same protocol data type exists in the preset rule base; a second execution module, used to parse the HVAC unit protocol data to be processed by the preset parsing algorithm to obtain the parsing result if the same protocol data type does not exist in the preset rule base.

[0096] In this embodiment, the protocol data type is first compared and judged. After the type of HVAC unit protocol data to be processed is determined, it is only necessary to match the protocol data under the protocol data type. There is no need to match all the protocol data in the preset rule library. This can greatly improve the matching time of the protocol data and improve the matching speed of the protocol data.

[0097] Optionally, the conversion module 505 includes: a first conversion unit, used to convert the HVAC unit protocol data to be processed into standard protocol data according to preset protocol rules; a second conversion unit, used to convert the standard protocol data into target protocol data according to the protocol data type of the target HVAC unit to be sent.

[0098] In this embodiment, after the corresponding integrated protocol data is matched in the preset rule base, the HVAC unit protocol data to be processed can be converted into standard protocol data according to the preset protocol rules and protocol data types, and then the standard protocol data can be converted into the target protocol data corresponding to the target HVAC unit, so as to facilitate communication control of the target HVAC unit through the target protocol data. In this way, the target protocol data can be directly converted according to the preset protocol rules and protocol data types, which can improve the conversion speed of the target protocol data. This can improve the adaptability and efficiency of the HVAC unit.

[0099] Optionally, the parsing module includes: a parsing unit, used to parse the HVAC unit protocol data to be processed according to the protocol data type of the HVAC unit protocol data to be processed through the preset parsing algorithm to obtain parsed protocol data; a third conversion unit, used to convert the parsed protocol data into new standard protocol data through the preset conversion script; and a fourth conversion unit, used to convert the new standard protocol data into new target protocol data.

[0100] In this embodiment, after determining that there is no corresponding protocol data type in the preset rule library, or no corresponding integrated protocol data is matched, the HVAC unit protocol data to be processed can be analyzed by the preset parsing algorithm and the identified protocol data type, and then converted into new standard protocol data by the preset conversion script, and then the new standard protocol data is converted into new target protocol data. This facilitates the generation of protocol rules for new protocol data, realizes the inverse operation of protocol conversion, and facilitates the control of new HVAC units according to the new protocol rules in the later stage, so as to improve the adaptability of HVAC units and reduce management costs.

[0101] Optionally, the identification module includes: an extraction unit, used to extract protocol data features of the HVAC unit protocol data to be processed; a comparison unit, used to compare the protocol data features with preset protocol data type features, and determine the protocol data type of the HVAC unit protocol data to be processed based on the comparison results.

[0102] In this embodiment, in the process of processing the HVAC unit protocol data, the protocol data features of the HVAC unit protocol data to be processed can be first extracted, such as extracting the features of the protocol header in the protocol data, because many protocols contain a specific header at the beginning of the data packet, which is used to identify the protocol type and version. As long as the features of the protocol header are identified, the protocol data type of the corresponding protocol data can be known. Of course, in many known protocol data, the corresponding protocol data type features are also known. After obtaining the protocol data type features of the HVAC unit protocol data to be processed, the protocol data type of the HVAC unit protocol data to be processed can be obtained after comparison with the known protocol data type features. In this way, comparison with the preset protocol data type features can quickly identify the protocol data category of the HVAC unit protocol data to be processed, thereby improving the adaptability of the protocol data of different HVAC units, and at the same time improving the centralized control management cost of different HVAC units.

[0103] Optionally, the device also includes: a first creation module, used to create the preset rule base; a second creation module, used to create the preset parsing algorithm, the preset parsing algorithm includes a word analysis algorithm and a grammatical analysis algorithm for parsing the HVAC unit protocol data to be processed; and / or and / or a third creation module, used to create the preset conversion script, the preset conversion script includes multiple protocol data conversion functions for converting the HVAC unit protocol data to be processed.

[0104] In this embodiment, firstly, a parsing algorithm, a preset conversion script, and a preset rule base are preset. The protocol data corresponding to the HVAC unit that needs to be centrally controlled and managed is parsed and converted to determine the protocol data type, convert the standard protocol data, and generate preset protocol rules. Then, the mapping relationship of the protocol data is correspondingly integrated in a database, and then a preset rule base is obtained, so that when communicating and controlling with the HVAC unit, it can quickly identify the match, and then communicate with the target HVAC unit, so as to achieve the centralized control adaptability of cross-manufacturer or cross-brand HVAC units and reduce the centralized management cost.
