[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0032] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0033] To address the technical problem of low efficiency in configuring communication protocols in existing technologies, this application provides a communication control method. First, the interface information matching the access device is determined, and then the corresponding protocol is queried based on data characteristics to establish communication. This allows for automatic configuration of protocols for different devices, thereby improving communication efficiency.

[0034] Figure 1 This is a flowchart illustrating a communication control method provided in this embodiment, as shown below. Figure 1 As shown, the method may include:

[0035] S10: In response to receiving target data from the access device, determine the characteristic information of the target data and the target interface information that matches the access device;

[0036] S20: Query the target protocol information corresponding to the access device based on the target interface information and feature information;

[0037] S30: Establish communication based on target protocol information.

[0038] The communication control method provided in this embodiment can be applied to a cloud network controller, or it can be applied to a server or other terminal that has the ability to control the cloud network controller, such as a terminal device that connects to the cloud network controller via Bluetooth, local area network or other means.

[0039] Here, a cloud-based network controller can also refer to a cloud-based network controller, which transmits data with access devices via a network. For example, a cloud-based network controller can implement the controller's control logic and functions on a general-purpose computing platform in the cloud, and utilize software-defined and virtualization technologies to implement control tasks, thereby reducing the development costs of controller hardware.

[0040] Optionally, the communication control method and cloud-based network controller provided in this embodiment can be applied to intelligent device control systems, such as building control systems. The cloud-based network controller and the access device do not need to be connected through a hardware interface.

[0041] In this embodiment, the access device can be a device that accesses the cloud-based network controller via a network. For example, the cloud-based network controller can receive data reported by the access device and control the access device. The target data can be data reported by the access device, such as heartbeat packets, data containing device status, data requesting control, etc.

[0042] In one embodiment, responding to receiving target data from the access device may include: responding to receiving the target data from the access device within a predetermined time period or a predetermined cycle. For example, the predetermined time period or predetermined cycle may be the time period or cycle during which the cloud network controller receives data reported by the access device.

[0043] In one embodiment, the characteristic information of the target data may include the data characteristics of the target data and the device characteristics of the access device. The data characteristics of the target data may be determined based on the content, data type, and identification information of the target data, while the device characteristics of the access device may be determined based on the identification information of the access device.

[0044] In one embodiment, the target interface information matching the access device can refer to the target interface information matching the access device and the target data. The target interface information can be hardware interface information.

[0045] In one embodiment, querying the target protocol information corresponding to the access device may include: querying the target protocol information corresponding to the access device in a predetermined database. Here, the target protocol information may include a protocol identifier of the target protocol, wherein the target protocol may be a communication protocol used to establish communication, and the protocol identifier may be a number of the target protocol or target protocol information, etc.

[0046] In one embodiment, the target protocol information may be a protocol component containing a protocol identifier and a dataset corresponding to the protocol identifier. The dataset may include the device type of the access device, the interface type used, the protocol type used, and location information related to the access device. Location information refers to the data type and data values ​​of the target data collected by the access device, such as temperature values ​​from a temperature sensor or rotational speed values ​​from a fan.

[0047] In one embodiment, the predetermined database may be a protocol component library, for example, in which multiple target protocol information may be stored. Each target protocol information may contain a mapping between a target protocol and a set of datasets.

[0048] In one embodiment, a set of target interface information and feature information can correspond to a target protocol information, and different target interface information and feature information can correspond to different target protocol information.

[0049] In one embodiment, establishing communication based on the target protocol information can refer to establishing communication with a host computer based on the target protocol information.

[0050] In one embodiment, establishing communication based on the target protocol information may include: parsing and storing the target data based on the target protocol information, and establishing communication based on the target protocol information.

[0051] In this way, by determining the interface information and data characteristics that match the access device in the cloud network controller, the matching protocol can be found more accurately and quickly. There is no need to manually configure the protocol for different access devices. Thus, even if the cloud network controller does not have a hardware interface, it can still automatically configure the protocol for communication, thereby improving the accuracy and efficiency of communication.

[0052] Since the cloud-based network controller lacks a hardware interface, it is necessary to avoid errors and improve accuracy when determining the target interface information that matches the access device. Therefore, in some embodiments, such as Figure 2 As shown, in step S10, determining the feature information of the target data and the target interface information matching the access device may include:

[0053] S11: Determine the feature information of the target data;

[0054] S12: Poll the data request information corresponding to multiple alternative interface information to determine the target interface information that matches the access device.

[0055] In one embodiment, multiple alternative interface information can be stored in a predetermined database. For example, the target protocol information can store a protocol identifier and a dataset corresponding to the protocol identifier. The dataset can contain interface information corresponding to the target protocol. All interface information in the predetermined database is the multiple alternative interface information.

[0056] In one embodiment, determining the target interface information that matches the access device may refer to the hardware interface information that simulates the access device as the target interface information that matches the access device.

[0057] In one embodiment, polling based on data request information corresponding to multiple candidate interfaces can refer to sending data request information corresponding to multiple candidate interfaces in a polling manner. For example, sending data request information corresponding to multiple candidate interfaces to the access device in a polling manner.

[0058] Here, data request information can be request information used to request specific data from the access device or to request a response.

[0059] In one embodiment, determining the target interface information that matches the access device may refer to determining the target interface information that matches the access device based on the response information of the access device in response to the data request information.

[0060] In this way, by polling data requests through multiple alternative interface information, the interface information supported by the access device can be quickly determined. Even when the cloud network controller does not have a hardware interface, it can quickly simulate the interface matched by the device, thereby improving the accuracy and efficiency of automatic protocol configuration.

[0061] In some embodiments, such as Figure 3 As shown, step S12 may include:

[0062] S121: Poll and send data request information corresponding to multiple alternative interface information;

[0063] S122: In response to receiving the response information from the access device, determine the data request information responded to by the response information;

[0064] S123: Determine that the alternative interface information corresponding to the data request information in the response is the target interface information that matches the access device.

[0065] Here, the data request information can be a data request frame, etc.

[0066] In one embodiment, polling and sending data request information corresponding to multiple alternative interface information can refer to the access device polling and sending data request information corresponding to multiple alternative interface information, or broadcasting and polling and sending data request information corresponding to multiple alternative interface information, etc.

[0067] In one embodiment, polling and sending data request information corresponding to multiple candidate interface information may include: polling and sending data request information corresponding to multiple candidate interface information based on a predetermined sending period. For example, the predetermined sending period may be 100ms, 200ms, 500ms, or 1s, etc.

[0068] In one embodiment, the data request information corresponding to different alternative interface information is different. For example, the request identifier carried by the data request information corresponding to different alternative interface information is different.

[0069] In one embodiment, the response information returned by the access device may be the response information returned by the access device in response to the data request information.

[0070] In one embodiment, receiving a response from the access device can refer to receiving the response from the access device within a predetermined time window. For example, the start and end times of the predetermined time window can be the start time of polling and sending data request information, and a predetermined duration after the end time of polling and sending data request information.

[0071] In one embodiment, determining the data request information in response to the response information may refer to determining the data request information to which the access device's response information is directed.

[0072] In one embodiment, the data request information in response to the response information can be determined based on the time when the response information is received from the access device. For example, the most recently sent data request information before the time when the response information is received from the access device can be determined as the data request information in response to the response information.

[0073] In one embodiment, the data request information in the response information can also be determined based on the request identifier carried in the response information. For example, the request identifier carried in the response information is the summary request identifier carried in the data request information responded by the access device.

[0074] In one embodiment, when the number of data request messages in the response information is greater than 1, determining the candidate interface information corresponding to the response data request information as the target interface information matching the access device may include: selecting target data request information that matches the feature information of the target data from the data request information in the response information; and determining the candidate interface information corresponding to the target data request information as the target interface information matching the access device.

[0075] In this way, by polling and sending data requests corresponding to different interface information, and determining the data request that matches the access device based on the response of the access device, the corresponding interface information can be determined more accurately.

[0076] In some embodiments, determining the feature information of the target data includes:

[0077] The characteristic information of the target data is determined based on at least one of the content of the target data, the type of the target data, the identification information of the target data, and the identification information of the access device.

[0078] In one embodiment, the content of the target data may include the numerical value, unit, and data name of the target data. For example, the data name may include voltage value, current value, temperature value, and water level value. The type of the target data may refer to the data type of the target data, such as binary type and enumeration type.

[0079] In one embodiment, the identification information of the access device may refer to the unique identification code of the access device, such as the International Mobile Equipment Identity (IMEI).

[0080] In this way, the feature information of the target data can characterize the data and the access device in multiple dimensions, thereby more accurately determining the matching communication protocol and improving the reliability of data transmission.

[0081] In some embodiments, step S10 may include:

[0082] In response to receiving target data from the access device, the target data is cached in the storage area, and the characteristic information of the target data and the target interface information matching the access device are determined.

[0083] In one embodiment, caching the target data in a storage area may include: filtering the target data based on a controller identifier carried by the target data; and caching the filtered target data in the storage area. Here, the controller identifier can be a unique identifier for the network controller, and the controller identifier can be used to determine whether the target data is destined for the current network controller.

[0084] In one embodiment, caching the target data in a storage area may include: binding the target data with the identification information of the access device and then caching it in the storage area. For example, this step may include: filtering the target data based on the controller identifier carried by the target data; binding the filtered target data with the identification information of the access device and then caching it in the storage area.

[0085] In this way, after receiving data uploaded by the access device, caching it and then performing the protocol configuration process can avoid the loss of target data or the direct storage in memory, which would consume too many resources.

[0086] In some embodiments, establishing communication based on the target protocol information includes:

[0087] Read the cached target data from the storage area;

[0088] The target data is parsed based on the target protocol information;

[0089] The parsed target data is stored in the data table corresponding to the target protocol information;

[0090] The target protocol information is sent to the host computer so that the host computer can obtain the target data based on the target protocol information.

[0091] In one embodiment, the data table corresponding to the target protocol information can be determined based on the data table model contained in the target protocol information. For example, the data table model can indicate the rows, columns, data categories, and data locations in the data table.

[0092] In one embodiment, the target data, the instance corresponding to the access device, and the attribute information of the instance can form a mapping relationship, and the arrangement of the data table can reflect the above mapping relationship.

[0093] In one embodiment, sending the target protocol information to the host computer can refer to sending the protocol identifier in the target protocol information to the host computer, for example, the protocol identifier being a protocol number. The host computer can then obtain the corresponding target data from the network controller based on the protocol identifier.

[0094] In this way, by parsing the cached target data through the matching protocol and storing it in the data table corresponding to the protocol, the target data can be stored more accurately in the matching data table. Thus, the host computer can quickly and accurately obtain the required data based on the target protocol information, thereby improving communication efficiency.

[0095] In some embodiments, after step S20, the method may further include:

[0096] In response to receiving a data acquisition request from a host computer, the target data is determined based on the target protocol information indicated by the host computer;

[0097] The target data is sent to the host computer.

[0098] In one embodiment, determining target data based on the target protocol information indicated by the host computer may include: querying the target data corresponding to the protocol identifier carried in the data acquisition request.

[0099] In one embodiment, sending the target data to the host computer may include: reading part or all of the target data from a data table and sending the target data to the host computer.

[0100] In one embodiment, after sending the target data to the host computer, the method may further include: determining whether the target protocol information matches the access device based on the reception status of the data acquisition request and the transmission status of the target data; if they do not match, then re-determining the target protocol information corresponding to the access device.

[0101] Here, re-determining the target protocol information corresponding to the access device may include: determining the feature information of the target data and the target interface information matching the access device; and querying the target protocol information corresponding to the access device in a predetermined database that does not contain the current target protocol information based on the target interface information and the feature information.

[0102] In this way, the host computer can obtain the required target data based on the matched target protocol information. Through automatic protocol configuration, the data transmission configuration between the network controller and the host computer is realized, improving the efficiency and accuracy of communication.

[0103] As one possible implementation, a cloud-based network controller (hereinafter referred to as the controller) is provided, and based on this, a method for self-adaptation of device access protocols is proposed to realize the process from device access to data parsing through protocols and then to data display on the host computer interface. For example... Figure 4 As shown, the entire building control system architecture is illustrated. The controller's structural components are as follows: Figure 5As shown, it mainly consists of a central processing unit, a virtual hardware interface processing unit, a protocol component library, a data comparison unit, and a data storage area. The control system's workflow is as follows: Figure 6 As shown, it includes:

[0104] The central processing unit is mainly responsible for data processing and scheduling the work of other units. It also has an internal storage area for storing subsequently generated data tables.

[0105] The virtual hardware interface processing unit mainly virtualizes the necessary hardware interfaces for devices connected to the network controller, such as... Figure 7 As shown, it mainly works by polling and sending data request frames (data frames) according to the hardware interface information in the protocol component library, and then checking whether the access device has successfully responded to the data request. If a response to the data request is successfully received, it indicates that the hardware interface information adapted to the device has been successfully matched, and the data access request of the hardware interface is simulated based on this information, thereby achieving the purpose of simulating the hardware interface and thus more quickly matching the protocol component suitable for the access device (different protocols correspond to different data frame formats, while hardware interfaces and protocols are one-to-one, such as CAN interface corresponding to CAN bus protocol, RS485 interface corresponding to RS485 bus protocol, etc.).

[0106] The data comparison unit primarily filters the received data. Then, based on the interface type information and data characteristics virtualized by the virtual hardware interface processing unit, it compares and searches the protocol component library for components that match the device. It has an internal storage area to cache the received data. Data filtering mainly involves identifying the sequence number in the first segment of the received data. Typically, it can be stipulated that devices connected to the controller need to add the controller's serial number to the first segment of the data when transmitting data. This serial number is a unique identifier generated by the controller. By identifying this serial number, the data uploaded by the devices connected to the controller can be filtered out.

[0107] The protocol component library primarily stores standardized protocol components for all current devices. Each protocol component is numbered. A protocol component is a collection containing information about the device type, interface type, protocol type, and location information associated with that device. Location information refers to the data and values ​​collected by that device, such as temperature values ​​from a temperature sensor or rotational speed values ​​from a fan. The data storage area primarily stores all data transmitted to the network controller from currently connected devices.

[0108] The network controller's workflow is as follows: Figure 8 As shown, it may specifically include:

[0109] First, when a device connects to the network controller (via Wi-Fi, Ethernet, etc.), the virtual hardware interface processing unit within the network controller detects the data characteristics sent by the device and virtualizes the device's hardware interface. The data characteristics consist of the data type (binary or enumerated), the device's unique identifier, and the content of the data (such as voltage, current, temperature, water level, etc.). The unique identifier is used to distinguish different devices, such as the IMEI code. The interface type is one of the common CAN communication interfaces, RS485 interfaces, or I2C.

[0110] After completing the virtualization of the access device's hardware interface, the virtual hardware interface processing unit sends the interface information and data characteristics to the data comparison unit. Simultaneously, it temporarily stores the data transmitted by the device in the data storage area. Upon receiving the device's data characteristics and interface type, the data comparison unit matches the appropriate protocol component from the protocol component library corresponding to that interface type. Since the data types transmitted by various devices can be broadly categorized into nine types, device instances can be mapped according to the data category uploaded. A device can have multiple instances, each containing multiple attributes. A mapping relationship is established between data types, instances, and attributes. This method constructs a flat data storage model, such as... Figure 9 As shown.

[0111] For example, a device for measuring water level and water pressure has instances of water level and water pressure measurement values. The current measurement value of water level and water pressure is the attribute of the corresponding instance. The data type of the two instances of water level and water pressure is real number read-only, which corresponds to analog input. In addition, there is an alarm status of water level and water pressure, which is divided into alarm and no alarm, i.e., 0 and 1. The corresponding data type is binary value read-only, which corresponds to binary input. The instances of this are the alarm status of water level and water pressure, and the attribute is alarm and no alarm, with the attribute value being 0 and 1.

[0112] Protocol components in the protocol component library are stored according to a mapping relationship between data type and device attributes, which is the flat data storage model. After matching the protocol component of the device, the data comparison unit sends the matched protocol component number to the central processing unit. The central processing unit retrieves the protocol component from the protocol component library and generates a data table according to the data storage model. Then, the central processing unit parses the data in the data storage area according to the matching protocol and stores it in the data table. At the same time, after matching the protocol component of the device, the number of the matched protocol component is sent to the host computer. Subsequently, the host computer uses its protocol component to find the location of the device's data stored in the data table to retrieve the data, thus completing the communication connection between the device, the device, and the host computer. This allows data to be displayed on the host computer platform as soon as the device is connected, achieving configuration-free operation of protocol points.
