Detailed ways

In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

The edge gateway communication method provided in this application can be applied to the application environment shown in FIG. 1 . The edge gateway 104 communicates with the protocol configuration terminal 102 and the device 106 through the network. in,

The edge gateway 104 can be implemented with an intelligent router with gateway function or with a dedicated gateway product. The protocol configuration terminal 102 may be a cloud platform or protocol configuration software. Device 106 may be a smart device with computing capabilities. Device 106 may be an Internet of Things device. Devices 106 include, but are not limited to, various personal computers, laptops, smart phones, tablet computers, portable wearable devices, smart TVs, smart speakers, smart air conditioners, smart printers, and the like.

In one embodiment, as shown in FIG. 2 , an edge gateway communication method is provided, and the method can be implemented by an edge gateway, and can also be implemented by interaction between the edge gateway and a protocol configuration terminal. Now, the method is applied to the edge gateway in Fig. 1 as an example to illustrate, including the following steps:

Step 202, the edge gateway obtains target protocol configuration data configured by the protocol configuration terminal; the target protocol configuration data is the protocol configuration data pre-configured by the protocol configuration terminal corresponding to the device type of the target device to be communicated.

Among them, the edge gateway is a gateway that is deployed on the edge side of the network and has edge computing capabilities. The edge gateway can connect the protocol configuration side through the network, and connect the device side through the network and protocol conversion function. It can be understood that the edge gateway can obtain the target protocol configuration data configured by the protocol configuration end through the communication connection with the protocol configuration end. It can be understood that the edge computing capability of the edge gateway can be used to analyze data related to devices and other related data in real time and provide lightweight connection management.

A protocol, short for a network protocol, is a pre-agreed rule that both parties must follow when an edge gateway communicates with a device. It can be understood that the communication between the two parties can only be achieved by encapsulating or unpacking data according to the agreed protocol rules.

The protocol configuration terminal is used to configure the corresponding protocol configuration data for the device type.

In one embodiment, the protocol configuration terminal may be a device installed with protocol configuration software, or may be a cloud platform or the like. The protocol configuration software is software for performing protocol configuration (ie, software with a protocol configuration function).

The target device refers to the device to be communicated with by the edge gateway, that is, the device to be communicated with by the edge gateway.

The target protocol configuration data is the protocol configuration data pre-configured by the protocol configuration end corresponding to the device type of the target device to be communicated. The protocol configuration data is the configured protocol data. That is, the protocol data to be used between the target device and the edge gateway is pre-configured in the protocol configuration terminal, that is, the target protocol configuration data is obtained.

In one embodiment, the target protocol configuration data includes a configured communication process and a configured protocol data structure.

Specifically, a technician can configure the protocol configuration data correspondingly to the device type of the target device at the protocol configuration end in advance. When the edge gateway needs to communicate with the target device, it can obtain the target protocol configuration data configured by the protocol configuration terminal to prepare for communication with the target device.

It can be understood that when the edge gateway wants to communicate with the target device, the edge gateway can request to download the configured target protocol configuration data from the protocol configuration terminal, or directly obtain the stored protocol configuration terminal from the local edge gateway. target protocol configuration data.

Step 204: Read the communication flow configured in the target protocol configuration data.

The communication process refers to the communication process agreed between the edge gateway and the user equipment. It can be understood that when the edge gateway communicates with the user equipment, the communication needs to be performed according to the communication process configured in the target protocol configuration data.

It can be understood that the communication process may include information such as the agreed communication method, the total required communication steps, the meaning represented by each communication step, and the sequence between the communication steps.

It should be noted that the communication processes defined by different protocols are different, that is, devices using different protocols have different communication processes. Therefore, the edge gateway can obtain the protocol configuration data of devices using different protocols from the protocol configuration terminal, and communicate with each device according to the communication process configured in the protocol configuration data.

For example, the communication process corresponding to the Mitsubishi series equipment (that is, the equipment using the Mitsubishi communication protocol) is "the gateway reads, the equipment replies to the data, and the gateway replies to the confirmation information", but the Modbus-RTU equipment (that is, the equipment that uses the modbus communication protocol), The communication process only needs "the gateway reads, the device replies data".

Specifically, the edge gateway reads the acquired target protocol configuration data, and obtains a communication process defined in the target protocol configuration data corresponding to the target device.

Step 206 , for the current to-be-executed process in the communication process, perform data protocol encapsulation according to the protocol data structure configured in the target protocol configuration data to obtain a communication data packet corresponding to the current to-be-executed process.

Wherein, the current process to be executed refers to the current process to be executed by the edge gateway in the communication process.

The protocol data structure is the defined data communication format.

In one embodiment, the configured protocol data structure may include the defined meaning and field length of each field, and the data source to which the field is bound, or the data of the field is directly bound.

For example: the first byte of the Mitsubishi series protocol is the start character, the second byte is the device station number, the start character is fixed to the specified character, the device station number is bound to the device unit number mounted in the gateway configuration, etc.

The data protocol packet is the process of filling the data to be sent according to the protocol data structure and converting it into the target data form.

The communication data packet is the data packet obtained after the data protocol is encapsulated and sent to the device.

Specifically, the edge gateway further learns the current to-be-executed process from the communication process that is configured in the read target protocol configuration data and corresponds to the communication process defined by the device manufacturer. The edge gateway can perform data protocol packetization according to the protocol data structure configured in the target protocol configuration data, so as to obtain the communication data packet corresponding to the current process to be executed.

Step 208, the edge gateway delivers the communication data packet to the target device.

The delivery refers to the action of sending communication data packets to the device on the edge gateway side.

Specifically, the edge gateway confirms that the network connection to the device is in a normal state and there is no network disconnection, and then sends a communication data packet corresponding to the current process to be executed to the device.

Step 210: The edge gateway receives the reply data packet returned by the target device for the communication data packet, and unpacks the reply data packet according to the protocol data structure to obtain reply data.

Among them, the reply data packet is the data packet returned to the edge gateway by the device end according to the protocol data structure pre-configured by the manufacturer for the data returned by the edge gateway request, which contains the real-time information of the device end.

Unpacking is the data structure of the received data packet configured by the edge gateway or the device according to the protocol, and sequentially extracts useful data from the reply data packet.

Reply data, that is, the data that the device replies to represent the real-time information on the device.

Specifically, the device that communicates with the edge gateway, after receiving the communication data packet sent by the edge gateway, unpacks and extracts the actual data, learns the data required by the edge gateway, and then, according to the protocol data structure pre-configured by the manufacturer After performing data protocol packets on the data returned by the edge gateway request, it is returned to the edge gateway. After receiving the reply data packet returned by the target device for the communication data packet, the edge gateway unpacks the reply data packet according to the protocol data structure to obtain reply data, thereby realizing the communication between the edge gateway and the device.

In one embodiment, in a specific embodiment, refer to FIG. 3 for a system architecture diagram of an edge gateway communication method. The protocol configuration terminal, that is, the "protocol configuration software" or "cloud platform", issues the protocol. The edge gateway receives the target protocol configuration data sent by the protocol configuration terminal, and performs data protocol encapsulation/protocol unpacking according to the target protocol configuration data to realize communication with the target device.

In the above-mentioned edge gateway communication method, device, computer equipment and storage medium, the edge gateway directly obtains the target protocol configuration data corresponding to the device type of the target device to be communicated from the protocol configuration end, without the need to fix the development protocol to the edge gateway. Based on the communication process configured in the target protocol configuration data, the edge gateway can know the current process to be executed, and perform data protocol packetization according to the protocol data structure configured in the target protocol configuration data to obtain the communication data packet corresponding to the current process to be executed. The edge gateway sends communication data packets to the target device. Since the packet is based on the protocol data structure configured corresponding to the device type of the target device, the communication data packet sent can be identified by the target device, and then the edge gateway receives the reply data packet returned by the target device for the communication data packet, And according to the protocol data structure, the reply data packet is unpacked to obtain the reply data. Therefore, the communication between the edge gateway and devices supporting various protocols can be realized through flexible protocol configuration, the problem of protocol conversion of the edge gateway is solved, and the applicability of the edge gateway is effectively improved.

In one embodiment, the edge gateway obtains the target protocol configuration data configured by the protocol configuration terminal, including: after the edge gateway is started, detecting whether there is local target protocol configuration data configured corresponding to the device type of the target device; The edge gateway reads the target protocol configuration data locally; when it does not exist, the edge gateway obtains the target protocol configuration data from the protocol configuration side.

Specifically, after the edge gateway is started, the edge gateway will first detect in its local storage folder whether there is target protocol configuration data configured corresponding to the device type of the target device. If the local storage folder stores the target protocol configuration data, the edge gateway directly reads the target protocol configuration data from the local folder. If the local storage folder does not store the target protocol configuration data, the edge gateway needs to obtain the target protocol configuration data from the protocol configuration side.

In a specific embodiment, referring to the schematic flowchart of the steps of the edge gateway communication method in FIG. 4, it is shown that after the edge gateway is started, it will detect whether there is local target protocol configuration data corresponding to the device type of the target device, that is, " Check if there is corresponding protocol configuration data". When the target protocol configuration data exists, the edge gateway reads the target protocol configuration data locally, that is, "read configuration".

In this embodiment, the edge gateway detects whether the local storage folder stores the target protocol configuration data configured corresponding to the device type of the target device, which can reduce the workload of self-detection by the background staff.

In one embodiment, when it does not exist, the edge gateway obtains the target protocol configuration data from the protocol configuration terminal, including: when it does not exist, sending alarm information; receiving the target protocol configured and delivered by the protocol configuration terminal for the alarm information Configuration Data.

The alarm information is sent by the edge gateway, and is used to inform the staff that no target protocol configuration data is stored in the local storage folder of the edge gateway.

Specifically, when the edge gateway detects that the local storage folder does not store the target protocol configuration data, it sends an alarm message to inform the staff that the edge gateway cannot be used normally and lacks the proper protocol configuration data. The staff goes to the protocol configuration end to configure the target protocol configuration data for the alarm information. The target protocol configuration data sent by the protocol configuration end is sent to the edge gateway.

In one embodiment, when it does not exist, the edge gateway obtains the target protocol configuration data from the protocol configuration terminal, including: when it does not exist, the edge gateway sends a protocol configuration download request to the protocol configuration terminal; and receives the protocol configuration terminal for the protocol configuration terminal. The target protocol configuration data returned by the download request.

In a specific embodiment, when the edge gateway detects that the local storage folder does not store the target protocol configuration data, it sends a protocol configuration download request to the protocol configuration end. If the target protocol configuration data returned by the protocol configuration end for the protocol configuration download request can be successfully received, there is no need to send alarm information to the staff.

In this embodiment, the edge gateway automatically checks that the local storage folder does not contain the target protocol configuration data, and then automatically requests the protocol configuration terminal to deliver it, and no longer sends an alarm to the relevant staff if the target protocol configuration data can be received. The terminal cannot deliver the target protocol configuration data, and then sends an alarm message to inform the staff to go to the protocol configuration terminal to configure the target protocol configuration data. Therefore, it can help the staff to judge that the alarm information is issued because the target protocol configuration data is not configured properly at the protocol configuration end.

In one embodiment, before the edge gateway obtains the target protocol configuration data configured by the protocol configuration terminal, the method further includes: when the edge gateway is deployed, receiving the target protocol configuration data delivered from the protocol configuration terminal and storing it locally; The edge gateway obtains the target protocol configuration data configured by the protocol configuration terminal, including: the edge gateway obtains locally stored target protocol configuration data.

Specifically, before the edge gateway obtains the target protocol configuration data configured by the protocol configuration terminal, the edge gateway will be deployed first. When deploying the edge gateway, the technician can first define and edit the protocol data structure on the protocol configuration terminal to adapt to the After editing the protocol used by the target device, the target protocol configuration data is obtained, and the target protocol configuration data is sent to the edge gateway through wired/wireless. The edge gateway can locally store the target protocol configuration data delivered from the protocol configuration end. After the edge gateway is deployed and started, the stored target protocol configuration data can be obtained locally.

In this embodiment, when the edge gateway is deployed, the target protocol configuration data is received and stored locally. The staff does not need to trigger the deployment completion control after completing the edge gateway deployment, and the edge gateway will then receive the target protocol configuration data, which can reduce work. The waiting time of personnel, if the download is successful, can also further reduce the subsequent staff's inspection of the deployment of the edge gateway, thereby reducing the workload of the staff and speeding up the progress of the project.

In one embodiment, for the current to-be-executed process in the communication process, perform data protocol encapsulation according to the protocol data structure configured in the protocol configuration data to obtain the communication data packet corresponding to the current to-be-executed process, including: for the current process in the communication process In the process to be executed, according to the protocol data structure configured in the protocol configuration data, for the defined protocol field, fill in the data corresponding to the data source bound to the protocol field, or fill in the data bound by the protocol field; The data is converted into the target data format, and the communication data packet corresponding to the current process to be executed is obtained.

Among them, the device protocol is essentially a string of data. To communicate with the device, we need to write the corresponding data in the corresponding protocol field according to the protocol data structure formulated by the device manufacturer to realize communication.

It can be understood that, for different protocols, the data types of the data written corresponding to the protocol fields are different. For example, the data type of Mitsubishi series protocol is ASCII stream, and the data type of Modbus-RTU protocol is hexadecimal.

Data source refers to the source of substantial data.

It can be understood that when the protocol field is bound to data instead of the data source, it is not necessary to fetch the corresponding data through the data source, but directly fill the bound corresponding data into the protocol field.

Specifically, for the current to-be-executed process in the communication process, according to the protocol data structure configured in the protocol configuration data, for the defined protocol field, the edge gateway takes out substantial data to fill in the data source bound to the protocol field. In the protocol field, the data obtained after filling is converted into the target data format, and the communication data packet corresponding to the current process to be executed is obtained.

In a specific embodiment, when the data bound to the protocol field is not the data source, the data bound to the protocol field is directly filled, and the data obtained after filling is converted into the target data format, and the obtained data is obtained with the current pending data format. Execute the communication data packet corresponding to the process.

In a specific embodiment, referring to the schematic flowchart of the steps of the edge gateway communication method in FIG. 4 , the process of performing data protocol encapsulation by the edge gateway is shown. For the current to-be-executed process in the communication process, the data protocol packet is performed according to the protocol data structure configured in the protocol configuration data, which corresponds to the steps of "execute the communication process according to the protocol configuration" and "fill data according to the protocol field information" in FIG. 4 . .

In this embodiment, the edge gateway obtains the target protocol configuration data configured by the protocol configuration terminal, and according to the protocol data structure configured in the target protocol configuration data, for the defined protocol field, fills in the data corresponding to the protocol field, or fills in the protocol field bound data. Then, the data obtained after filling is converted into a target data format, and a communication data packet corresponding to the current process to be executed is obtained. The entire protocol configuration process does not need to manually set the protocol configuration of the edge gateway in advance, but obtains it through the protocol configuration terminal. It does not need to manually fill in the protocol data but fills it by itself. Therefore, the edge gateway can be adapted to the equipment of different manufacturers. Improves the adaptability of edge gateways.

In one embodiment, the method further includes: after the edge gateway delivers the communication data packet to the target device, when the communication with the target device is normal, executing the step of receiving the reply data packet returned by the target device for the communication data packet by the edge gateway ; When the communication with the target device is abnormal, the edge gateway will re-deliver communication data packets to the target device; when the number of re-delivery times reaches the preset number of times threshold, and the communication with the target device is still abnormal, a protocol configuration error alarm will be issued information.

Specifically, after the edge gateway sends the communication data packet to the target device, if the communication with the target device is normal, the device can receive the communication data packet sent by the edge gateway. The device unpacks the communication data packets sent by the edge gateway according to the protocol data structure, extracts the required essential data, and learns the essential data that the edge gateway needs to reply. The device encapsulates the substantial data that the edge gateway needs to reply to according to the data protocol structure, and sends the reply data packet to the edge gateway.

When the edge gateway does not obtain the reply data packet uploaded by the device, exceeds the preset duration threshold, and judges that the communication with the target device is abnormal, the edge gateway re-executes the delivery of the communication data packet to the target device.

When the number of re-delivery times reaches the preset number of times threshold and the communication with the target device is still abnormal, a protocol configuration error alarm message is sent.

In a specific embodiment, referring to the schematic flowchart of the steps of the edge gateway communication method in FIG. 4 , it is shown that when the edge gateway communicates with the device, it will "determine whether the device communicates normally". When the device receives the communication data packet sent by the gateway, that is, "received data", it will judge whether the protocol is correct and the protocol is correct. After the data protocol is packaged according to the protocol data structure, the device will upload the reply data packet to the edge gateway. If the reply data packet uploaded by the device can be received, it is a normal communication, and the reply data packet uploaded by the device will be unpacked, that is, "extract data according to the protocol configuration". If the reply data packet uploaded by the device has not been received after the preset duration threshold, it is first determined whether there is a problem in the process of sending the communication data packet, that is, the edge gateway will send the communication data packet again. In this real-time example, the preset threshold for the number of re-delivery times is 3 times. After the re-delivery of the communication data packet arrives three times, if the reply data packet uploaded by the device has not been received after the preset duration threshold, a protocol configuration error alarm message is sent.

In this embodiment, by acquiring the reply data packet uploaded by the device, the edge gateway unpacks the reply data packet to extract substantial data, and uploads it to the cloud platform.
