Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a data transmission method and communication equipment. Background Art

[0002] In application scenarios such as industrial automation, remote monitoring, and intelligent control, 485 devices (various devices using RS-485 communication protocol) usually need to be connected to a higher-level system for centralized management and control. In this case, the information of the 485 device can be converted into a serial port message that can be recognized by the communication device through a conversion device (such as a smart switch), so as to communicate with the cloud or other systems through the communication device.

[0003] In the related art, a smart switch is used to convert the information of a 485 device into serial port information with a fixed identifier and send it to a communication device. The communication device converts the serial port information with a fixed identifier into cloud information and sends it to the cloud, wherein the fixed identifier is used to identify the 485 device and a certain function of the 485 device. When there are multiple 485 devices connected to the cloud, corresponding fixed identifiers are set for the functions of different 485 devices. For example, the switch function of the light, the fixed identifier is set to 1001; the switch function of the air conditioner, the fixed identifier is set to 1002; the switch function of the bathroom heater device, the fixed identifier is set to 1003. It can be seen that when any new 485 device is connected to the communication device, a corresponding fixed identifier must be set for each function of the new 485 device. This access method causes the cloud or communication device to maintain a large amount of device data, resulting in low data transmission efficiency during the access and control process of the 485 device.

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions 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.

[0026] See also Figure 1 As shown in FIG. 1 , it is an application scenario diagram of the data transmission method provided in the embodiment of the present application. Figure 1 As shown, the smart switch 200 includes a wired communication module, and the access device 100 is connected to the wired communication module by wired communication. The smart switch 200 is connected to the communication device 300 through a network, and the communication device 300 is connected to the server 400 through a network. The network includes but is not limited to a wired network and a wireless network.

[0027] In order to implement remote monitoring and management of the access device 100, the server 400 needs to obtain the device status information of the access device 100. The access device 100 can actively report the status information, or respond to a status acquisition instruction and report the status information according to the status acquisition instruction.

[0028] The smart switch 200 receives the status information sent by the access device 100, synchronously obtains the device address of the access device 100, and then converts the device address and status information of the access device 100 into a message format that the communication device 300 can understand and process, for example, encapsulating the device address and status information of the access device 100 to generate a status reporting instruction, and sending the status reporting instruction to the communication device 300.

[0029] The communication device 300 responds to the status reporting instruction and determines the device address and status information of the access device 100 according to the status reporting instruction. According to the device address of the access device 100, the communication device 300 can determine the device information of the access device 100. After obtaining the device information and status information of the access device 100, the communication device 300 can generate the object model information of the access device 100 based on the device information and status information, and send the object model information to the server 400. The server 400 receives the object model information of the access device 100 and can update the pre-stored device status information of the access device 100 according to the object model information.

[0030] In some embodiments, the correspondence between the function identifier and the function may be stored in the communication device 300 or the server 400. The function identifier is used to uniquely identify a certain function, for example, 1000 is used to identify a switch function. The same function of different access devices 100 has the same function identifier.

[0031] In an embodiment of the present application, the identity of the access device 100 is determined by utilizing the device address of the access device 100, thereby distinguishing the identification device from the identification function, thereby allowing a unified identification for the same functions of different devices, without the need to set function identifications for each function of the access device 100, thereby saving storage space and effectively improving the efficiency of data transmission.

[0032] In some embodiments, the wired communication module of the intelligent switch 200 includes at least one of the following: a communication unit based on 485 communication standard (RS-485), a communication unit based on 232 communication standard (RS-232), and an Ethernet communication unit.

[0033] In some embodiments, the communication device 300 may be a device such as a gateway. The server 400 may be a cloud server, an independent server, or a server cluster. The communication device 300 may be connected by wire to electrically connect the gateway to the bottom housing circuit board in the smart switch, thereby connecting the communication device 300 to the smart switch 200.

[0034] Figure 1The scenarios shown are only illustrative examples, and the device control method provided in this application can also be applied in other scenarios. For example, in some scenarios, multiple access devices 100 may be included; in some scenarios, multiple servers 400 may be included; in some scenarios, other types of devices may also be included. The embodiments of this application do not limit the specific application scenarios of the device control method.

[0035] See also Figure 2 The figure is a flowchart of the implementation of the data transmission method provided in the embodiment of the present application. The method is applied to a communication device. The embodiment of the present application is applied to the method in Figure 1 The communication device 300 in FIG. 1 is used as an example for explanation. The method includes the following steps.

[0036] S11: responding to the status reporting instruction of the access device sent by the intelligent switch, and determining the device address and status information of the access device according to the status reporting instruction.

[0037] In some embodiments, the status reporting instruction includes the device address and status information of the access device. The communication device can obtain the device address and status information of the access device by parsing the status reporting instruction.

[0038] In some embodiments, the status information includes information such as function identification and status identification. The same function of different access devices has the same corresponding function identification. For example, when the access device is an air conditioner, the function identification of the switch function of the air conditioner is 1000, and when the access device is a smart light, the function identification of the smart switch function is also 1000.

[0039] In some embodiments, the device address is used to determine the identity of the access device. The function identifier is used to determine which function type reported by the access device corresponds to the status information. For example, when the function identifier of the switch function is 1000, if the function identifier is determined to be 1000, the communication device can determine that the access device reports the update information of the device switch status. The status identifier is used to characterize the type of status. For example, for the switch function, when the status identifier is 1, it indicates the on state, and when the status identifier is 0, it indicates the off state. The communication device can determine the status of the corresponding function of the access device based on the function identifier and the corresponding status identifier.

[0040] S12: Determine device information of the access device according to the device address.

[0041] In some embodiments, the device information includes but is not limited to the device type and device identification. The device type is used to characterize the category information of the access device. The device identification is used to identify the access device in the upper network (such as a server).

[0042] In some embodiments of the present application, the communication device determines the device information of the access device based on the device address, including: determining the device identification and device type of the access device based on the device address; determining the device information based on the device identification and device type.

[0043] In some embodiments, the communication device may pre-store the correspondence between the device address and the device identification. After acquiring the device address of the access device, the communication device may match and obtain the device identification of the access device according to the device address.

[0044] In the process of determining the device type of the access device, the communication device can generate a device type acquisition request based on the device address of the access device, and send the acquisition request to the smart switch. The smart switch receives the acquisition request, parses the acquisition request, obtains the device address, obtains the device type of the access device based on the device address, and returns the device type to the communication device.

[0045] In some embodiments, after the communication device obtains the device type and device identification of the access device, the relevant information including the device type and the device identification may be used as the device information of the access device.

[0046] In some embodiments of the present application, before determining the device information of the access device based on the device address, the method also includes: if the access device is a newly added device, generating a device identifier of the access device when the device address of the access device is received; updating the association between the device address and the device identifier to a preset device list, and sending the association to the server.

[0047] In some embodiments, the preset device list is used to store associations between different device addresses and device identifiers. The device identifier is used to identify access devices in an upper layer network (eg, a server).

[0048] In some embodiments, when the communication device determines a newly added device to the access device, it can generate a device identifier for the access device based on the device address of the access device, update the association between the device address and the device identifier of the access device to a preset device list, and send the association to the server.

[0049] In some embodiments, the communication device and the server store the association between the device address and the device identifier of the access device, so that when the information of the access device is received again, such as status reporting instructions and other information, the access device can be quickly located and the relevant information of the device can be obtained, or the relevant information of the device can be updated to improve data transmission efficiency.

[0050] After the association relationship between the device address and the device identifier of the access device is sent to the server, the server can determine the identity of the access device by identifying the device identifier.

[0051] In some embodiments of the present application, the device address of the access device is matched with a preset device list; if there is no address matching the device address in the preset device list, it is determined that the access device is a newly added device.

[0052] In some embodiments, the preset device list stores information that uniquely identifies the access device, such as the device address of the access device with the interaction history. Therefore, the communication device can determine whether the access device is a newly added device by matching the device address of the access device with the preset device list. If there is no address matching the device address in the preset device list, the access device is determined to be a newly added device. If there is an address matching the device address in the preset device list, the access device is determined to be a non-newly added device.

[0053] In some embodiments, the communication device may periodically maintain the preset device list. For example, the device data in the preset device list that has been stored for a period exceeding the preset period may be deleted. The preset period may be customizable. For the deleted device data, if the communication device receives the device address and other relevant device information of the device corresponding to the device data, the communication device may still regard the device as a newly added device.

[0054] In other embodiments, the method of determining whether the access device is a newly added device may further include determining whether the access device is a newly added device through an intelligent switch. If the access device is determined to be a newly added device, an instruction for the newly added device is generated according to the device address of the access device, and the instruction for the newly added device is sent to the communication device. The communication device may determine that the access device is a newly added device according to the instruction for the newly added device.

[0055] In this embodiment, when a new device is connected, the identity of the new device is determined by the device address, and there is no need to configure a fixed identifier to uniquely identify the device, which can save resources.

[0056] S13: Generate object model information of the access device based on the device information and status information, and send the object model information to the server.

[0057] In some embodiments, the object model is an abstract representation of the access device in the IoT environment, which is used to describe the attributes, services (or functions), events, tags and other dimensions of the access device, so that the (cloud) server can understand and operate the access device. The communication device or server can define the object model based on a description language in a format such as JavaScript Object Notation (JSON).

[0058] In some embodiments of the present application, physical model information of an access device is generated based on device information and status information, including: defining attribute information of the physical model according to the device information and status information; and generating physical model information according to the attribute information.

[0059] In some embodiments, the attribute information of the object model includes, but is not limited to, information describing the attributes of the access device, services (or functions), events, and other dimensions.

[0060] In some embodiments, the communication device can generate information describing the attributes of the access device based on the device information of the access device (including the device identification and device type), and can determine information describing the services (or functions) and events of the access device based on the status information of the access device. For example, the attributes of the access device include the device identification, device type, manufacturer information, etc. The services (or functions) of the access device may include operations or functions that the server can perform on the access device, such as turning on an operation (function) or turning off an operation (function). The access device includes actions triggered by the access device under certain conditions, such as when the status identification of the switch function is 1, it is determined that the access device is turned on.

[0061] In the data transmission method provided in the embodiment of the present application, the access device is identified by the device address. In the process of realizing the status reporting of the access device, the intelligent switch encapsulates the status information of the device address of the access device into the status reporting instruction, and sends the status reporting instruction to the communication device. The communication device receives the status reporting instruction, parses the status reporting instruction to obtain the device address and status information of the access device, determines the device information of the access device according to the device address, and generates the object model information of the access device based on the device information and status information, and reports the object model information to the server. The use of this method can save resources and improve data transmission efficiency.

[0062] See also Figure 3 , Figure 3 The figure is a flowchart of the implementation of the data transmission method provided by another embodiment of the present application. The method is applied to the smart switch. The embodiment of the present application is applied to the method as follows Figure 1 The intelligent switch 200 shown in FIG. Figure 3 As shown, the data transmission method provided in this embodiment includes steps S21 to S23, and the specific steps are as follows.

[0063] S21: When obtaining the device address and status information of the access device, a status reporting instruction is generated according to the status information and the device address.

[0064] In some embodiments, the smart switch obtains the device address and status information of the access device, and can convert the device address and status information of the access device into a message format that can be recognized by the communication device through the bottom shell of the smart switch. For example, in this embodiment, the smart switch generates a status reporting instruction based on the status information and the device address, and sends the status reporting instruction to the communication device.

[0065] In some embodiments, when the access device is first connected to the smart switch, the smart switch can obtain the device address of the access device and send the device address of the access device to the communication device. The communication device can generate a corresponding device identifier based on the device address of the access device, store the association between the device address of the access device and the device identifier, and send the association to the server.

[0066] In some embodiments, the intelligent switch can determine whether the access device is a newly added device based on the device address of the access device and other information used to uniquely identify the access device. If the device address of the access device is repeated with the device address in the historical record, the access device is determined to be a non-newly added device; if the device address of the access device is not repeated with the device address in the historical record, the access device is determined to be a newly added device.

[0067] S22: Sending a status reporting instruction to the communication device.

[0068] In some embodiments, the communication device receives the status reporting instruction and can parse the status reporting instruction to obtain the device address and status information of the access device. The communication device can obtain the device identification and device type of the access device according to the device address of the access device.

[0069] In the process of acquiring the device type of the access device, the communication device may generate device type query information according to the device address of the access device, and send the device type query information to the smart switch.

[0070] In some embodiments of the present application, when the smart switch receives device type query information sent by the communication device, it parses the device type query information to determine the device address to be queried; obtains the device type to be queried based on the device address to be queried; and sends the device type to be queried to the communication device.

[0071] In this embodiment, the device address to be queried includes the device address of the access device, and the device type to be queried includes the device type of the access device. The device type of the access device is used to indicate the category information of the access device.

[0072] In some embodiments, the intelligent switch can send a query instruction to the access device according to the access device address, obtain the device type of the access device, and then convert the device type of the access device into a message format recognizable by the communication device and send it to the communication device.

[0073] In some embodiments of the present application, if the interface communication protocol of the intelligent switch is the same as the communication protocol of the access device, a status reporting instruction is generated according to the status information and the device address.

[0074] In some embodiments, the premise for the access device and the smart switch to exchange data via a wired communication connection includes that the interface communication protocol supported by the smart switch is the same as the communication protocol of the access device. For example, a 485 device communicates based on the RS-485 communication protocol, so if the access device and the smart switch exchange data via a wired communication connection, the interface communication protocol of the smart switch needs to support the RS-485 communication protocol.

[0075] In some embodiments of the present application, the intelligent switch includes a wired communication module, the access device is communicatively connected to the wired communication module, and the wired communication module includes at least one of the following: a communication unit based on the 485 communication standard (RS-485), a communication unit based on the 232 communication standard (RS-232), and an Ethernet communication unit.

[0076] In other embodiments, the wired communication module may further include other communication units. The embodiment of the present application does not limit the wired communication module.

[0077] In the data transmission method provided in the embodiment of the present application, the identity of the access device is recognized through the device address of the access device, and there is no need to create a new fixed identifier for identifying the device identity, which can save resources and improve data transmission efficiency.

[0078] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
