[0024] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.

In view of this, "multiple" can also be understood as "at least two" in the embodiments of the present invention. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / ", unless otherwise specified, generally indicates that the previous and next associated objects are in an "or" relationship. In addition, it should be understood that in the description of the embodiments of the present invention, words such as "first" and "second" are only used to distinguish the purpose of description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order.

[0026] The background technology of the present invention is first introduced below.

[0027] In existing building automation systems, BACnet or Modbus communication protocols are mainly used to control equipment in the entire building. However, in actual application, different communication protocols have their own advantages and disadvantages, and none of them can fully meet actual needs. For example, although the BACnet communication protocol has a better content format and can meet the communication between different devices, it cannot maintain a connection and cannot meet the needs of Internet control; although the Modbus communication protocol is relatively simple and easy to implement, its positioning function is poor and it cannot accurately identify a certain device, so it still cannot meet the needs of reliable Internet control.

[0028] To solve the above technical problems, please see Figure 1An embodiment of the present invention provides a method for generating communication information, which is applied to building communication equipment. The method for generating communication information includes:

[0029] S10) obtaining a preset communication rule, wherein the preset communication rule is a communication rule based on information publishing / subscription;

[0030] S20) determining a first header and a second header based on the preset communication rule, wherein the first header is a fixed header and the second header is a variable header;

[0031] S30) determining a designated coding format corresponding to the building communication device, and implementing connection communication between the building communication devices based on the designated coding format;

[0032] S40) obtaining original communication information, performing an encoding operation based on the original communication information according to the specified encoding format, and generating corresponding encoding information;

[0033] S50) Generate corresponding building communication information according to the preset communication rule based on the first header, the second header and the coding information.

[0034] In one possible implementation, in order to achieve communication and information distribution between building communication devices, preset communication rules are first obtained. For example, in an embodiment of the present invention, the preset communication rules are communication rules based on information publishing / subscription, such as MQTT (Message Queuing Telemetry Transport). According to the MQTT protocol, the first header and the second header are first determined. Specifically, the fixed header and the variable header are first determined, and then the specified coding format corresponding to the building communication device is determined. For example, in an embodiment of the present invention, the specified coding format includes but is not limited to protocols such as the BACnet communication protocol or the Modbus communication protocol. Based on the above-mentioned specified coding format, building communication devices can achieve mutual communication connection.

[0035] See Figure 2 In an embodiment of the present invention, determining the designated coding format corresponding to the building communication device includes:

[0036] S31) determining a coding mode of the building communication device, and generating coding type information of the building communication device based on the coding mode;

[0037] S32) obtaining functional information of the building communication device, and generating corresponding service information based on the functional information;

[0038] S33) determining data storage rules;

[0039] S34) Generate a designated encoding format for the building communication device based on the property information of the building communication device, the encoding type information, the service information, and the data storage rule.

[0040] In one possible implementation, the encoding method of the building communication device is first determined. For example, if the building communication device encodes all fields in JSON, then the encoding method is JSON. Based on this encoding method, encoding type information for the building communication device is generated. For example, if JSON encoding is used, the encoding type information can be set to JSON. Functional information of the building communication device is then obtained. This functional information includes, for example, functions supported by the current building communication device or all building communication devices, specifically including but not limited to functions such as updating information, registering devices, obtaining device lists, feeding back device lists, and setting parameter values. Based on this functional information, corresponding service information is generated. For example, service information labeled Update, SignUpDevice, GetDeviceList, DeviceList, and SetObject can be generated. During communication, upon receiving communication information from other building communication devices, the server or building communication device performs corresponding service operations based on this service information.

[0041] At this point, data storage rules are further obtained. For example, the data storage rules include but are not limited to data content, storage format, storage location, and data processing methods (such as encryption rules, decryption rules, etc.). Then, based on the property information, encoding type information, service information, and data storage rules of the building communication device, a specified encoding format of the building communication device is generated. For example, in one embodiment, the specified encoding format is a set data structure, which is represented as follows in one example:

[0042]

[0043] In the actual communication process, different building communication devices encode the communication information according to the above-mentioned specified coding format and generate the final communication information for mutual communication, thereby effectively solving the technical problem that the existing communication rules based on information publishing / subscription cannot achieve direct communication between building communication devices.

[0044] After determining the designated coding format, original communication information is obtained, for example, the original communication information is communication information initially generated by a building communication device, and corresponding coding information is further generated based on the initially generated communication information.

[0045] See Figure 3 In an embodiment of the present invention, performing an encoding operation based on the original communication information in accordance with the specified encoding format to generate corresponding encoding information includes:

[0046] S41) extracting device attribute information and communication data information from the original communication information;

[0047] S42) determining a service field corresponding to the original communication information based on the service information;

[0048] S43) processing the communication data information based on the data storage rule to obtain processed data;

[0049] S44) Performing encoding operations on the encoding type information, the device attribute information, the service field, and the processed data based on the specified encoding format to generate corresponding encoding information.

[0050] In one possible implementation, the original communication information includes device attribute information of the building communication device (for example, including but not limited to device ID, device name, device IP address, and device geographic location), communication data information (control parameters and parameter values, etc.). During the encoding operation, the device attribute information and communication data information are first extracted from the original communication information. Then, based on the service information, a service field corresponding to the original communication information is determined. For example, the original communication information also includes a control command character, which indicates the type of service to be performed by the original communication information. The corresponding service field is determined from the service information based on the control command character. The communication data information is further processed according to the data storage rules, for example, a corresponding encryption operation is performed on the data in the communication data information to obtain the corresponding processed data. Of course, at the receiving end, a corresponding decryption operation, a verification operation, etc. can also be performed on the data in the building communication information according to the data storage rules. Finally, the encoding type information, device attribute information, service field, and processed data are converted into a corresponding data structure according to the specified encoding format, and the corresponding encoding information is generated.

[0051] Finally, according to the first header, second header and encoding information generated above, corresponding building communication information is generated according to the preset communication rules (such as MQTT). In the subsequent communication process, all building communication devices can communicate between devices and between devices and servers through the above building communication information, and at the same time realize reliable connection based on the Internet, thereby effectively solving the above communication problems existing in the existing technology and meeting the actual communication control needs.

[0052] On the other hand, see Figure 4An embodiment of the present invention further provides a communication method for a building automation system, which is applied to a server. The server communicates with a building communication device based on the building communication information provided by the embodiment of the present invention. The building communication information includes coding type information. The communication method for the building automation system includes:

[0053] S10) acquiring building communication information sent from the first building communication device;

[0054] S20) extracting a service field in the building communication information;

[0055] S30) determining a corresponding communication object based on the service field;

[0056] S41) If the communication object is a server, verifying the building communication information based on the coding type information, and if the verification result is passed, extracting communication data from the building communication information, and performing corresponding communication control operations based on the communication data;

[0057] S42) If the communication object is a second building communication device, forward the building communication information to the second building communication device.

[0058] Furthermore, in an embodiment of the present invention, determining the corresponding communication object based on the service field includes: if the service field is device registration or information subscription or obtaining a device list, determining that the communication object is a server; if the service field is updating information or setting parameter values ​​or information publishing, determining that the communication object is a second building communication device.

[0059] In one possible implementation, a building automation system includes a server and multiple building communication devices. Each building communication device is connected to the server and communicates via the building communication information. In one embodiment, a new building communication device is installed in a current building. Therefore, the building communication device needs to register itself with the server for network control. Therefore, the building communication device sends building communication information with a service field indicating device registration to the server. After receiving the building communication information, the server first extracts the service field and determines that the building communication device needs to register. Therefore, the communication object is determined to be the server itself. At this time, the building communication information is further verified based on the encoding type information. For example, by reading information corresponding to the Protocol in the building communication information, the encoding type of the current building communication information is determined. If the encoding type of the building communication information is not JSON, the verification is considered to have failed. If the encoding type of the building communication information is JSON, the verification is determined to have passed. At this time, the communication data in the building communication information is extracted, and corresponding communication control operations are performed based on the communication data. Specifically, various attribute information of the building communication device can be registered and stored in the server.

[0060] In a second embodiment, after receiving building communication information sent from a first building communication device, the server determines that the communication target is a second building communication device by parsing the service field. It should be noted that the second building communication device here can be multiple building communication devices. For example, when distributing building communication information from a first building communication device, the devices to receive the building communication information are multiple second building communication devices. In this case, the server can directly forward the building communication information to all of the second building communication devices. After receiving the building communication information, all second building communication devices parse the encoded information in the building communication information according to the specified encoding format determined above and perform corresponding communication control operations, thereby achieving online network control of building devices in the building automation system and communication connections between devices.

[0061] In an embodiment of the present invention, by improving the traditional building automation system, on the one hand, the communication information of the building automation system is improved at the bottom level, and coded information that allows communication between devices is inserted into the communication rules based on information publishing / subscription, thereby allowing building communication devices to be able to perform online network control in the cloud, and at the same time allowing building communication devices to communicate with each other reliably, meeting higher building control requirements; on the other hand, by improving the control framework of the building automation system, the server is directly connected to all building communication devices through configuration, and the building communication information of all connected building communication devices is intermediately processed or message published by the server, thereby realizing online management of the building automation system and meeting the actual needs of the enterprise.
