Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

An embodiment of the present invention provides a data transmission system, as shown in fig. 1, including an electronic device 10, a message middleware 20, and a control end 30. The electronic device 10 is configured to connect to devices of respective protocol types, and perform protocol conversion on received data by performing the data transmission method according to the embodiment of the present invention, for example, convert data of at least one protocol type into data of a target protocol, or convert data of the target protocol into data of at least one protocol type. The message middleware 20 is connected to the electronic device, and is configured to transmit data received from the control terminal to the electronic device, or transmit data received from the electronic device to the control terminal. The message middleware includes, but is not limited to, kafka and rockmq, and other types of message middleware may also be used, which are specifically set according to actual requirements. The control end 30 is connected to the message middleware 20, and is configured to process the received data, for example, perform library dropping on the received data, or perform processing of control logic to obtain a control instruction, and feed the control instruction back to the electronic device, and so on.

The data transmission system provided by this embodiment uniformly converts data of each protocol type into data of a target protocol by using the electronic device, or converts data of the target protocol into data of each protocol type, thereby implementing multiplexing of target protocol processing logic without maintaining processing logic corresponding to multiple protocol types, in a control process of device linkage, a control end only needs to process data of the target protocol, for the electronic device, message queues of different topics do not need to be subscribed, the unified target protocol is directly used for device linkage processing, efficiency of device linkage processing is improved, and real-time performance of linkage processing is ensured.

In some embodiments, fig. 2 shows a schematic diagram of a data transmission system, where the electronic device is a device access service gateway and the message middleware is Kafka. The protocol types connected by the equipment access service gateway comprise a lap protocol and a loraan protocol, specifically, an nbiot node is accessed to the service gateway through an operator base station by utilizing the lap protocol access equipment, wifi, 4G and 5G equipment are accessed to the service gateway through an mqtt protocol access equipment, and a lora node is accessed to the service gateway through a lora gateway by utilizing the loraan protocol access equipment.

The target protocol in the data transmission system is an mqtt protocol, and protocols which can be processed by the device access service gateway include a lap protocol and a lorawan protocol. When the equipment access service gateway processes uplink data, protocol type conversion is carried out by using access service corresponding to the protocol type of the equipment, the access service is uniformly converted into an mqtt protocol, and data are packaged into the mqtt protocol and uploaded to an Internet of things cloud platform in a bridging mode; when the equipment access service gateway processes the downlink data, the received downlink data are all encapsulated by adopting an mqtt protocol, and after the downlink data are received, the protocol type of the equipment corresponding to the downlink data is utilized to call the corresponding access service for protocol conversion, so that the downlink data are sent to the corresponding equipment.

The data transmission system serves as a single gateway through unified coach protocol, lorawan protocol and mqtt protocol access services. For the uplink (for example, the coach protocol, lorawan protocol) device data is converted into the mqtt protocol through the proxy layer after being accessed to the service gateway by the cloud device, the mqtt protocol data processing logic including device shadow, OTA and gateway sub-device capabilities is multiplexed, and the access rule does not need to be configured in advance. The downlink equipment control instruction is issued to an mqtt protocol access service in the equipment access service gateway through an mqtt protocol, and the mqtt protocol access service can automatically forward the access type of the current equipment ID to a corresponding protocol (coach, lorawan) access service through judgment, and then is finally issued to the equipment. Aiming at different equipment access protocols (maps, lorawn), rules do not need to be configured in advance, equipment is authenticated to access, data is reported, after the data reaches an equipment access service gateway, the data is all converted into an mqtt protocol, access service of the mqtt protocol is multiplexed, and finally the data of the equipment is bridged to Kafka by the mqtt protocol access service. The data from the mqtt protocol access service bridging data to the Kafka device can be respectively bridged to different Kafka themes according to the data types of device on-line and off-line, device attribute reporting, device event reporting, device instruction issuing and device instruction response, so that the data with high real-time requirement is ensured.

The data transmission system unifies the technical stack of the equipment access service into erlang language to replace java language, so that soft real-time, low-delay and high-concurrency capability of the equipment access gateway is ensured. The equipment access gateway simultaneously supports the access of three Internet of things communication protocols of mqtt, coach and lorawan, shields the coach protocol and the lorawan protocol for a sending end of a downlink instruction of equipment, and simplifies the issuing logic of the equipment instruction. The method comprises the steps of uniformly converting device data accessed by a coach protocol and a lorawan protocol into an mqtt protocol message at a gateway, multiplexing functions of device authentication, authorization and the like of an mqtt protocol device access service, realizing peak clipping decoupling by bridging to kafka, reducing maintenance cost of the device access service, and improving stability of the device access service in a high-concurrency scene. Meanwhile, equipment linkage is not realized among equipment with different access protocols by means of message queues, and downlink equipment instructions are all sent to the equipment access gateway through the mqtt protocol.

In accordance with an embodiment of the present invention, there is provided a data transmission method embodiment, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.

In this embodiment, a data transmission method is provided, which can be used in the above-mentioned electronic device, such as a device gateway, etc., fig. 4 is a flowchart of the data transmission method according to the embodiment of the present invention, and as shown in fig. 4, the flowchart includes the following steps:

and S11, acquiring the data to be processed of the first protocol.

The data to be processed of the first protocol is sent by a terminal connected with the electronic equipment, the terminal adopts the first protocol to carry out data transmission, and the data to be processed to be sent at the terminal side is packaged into the data to be processed of the first protocol according to the format requirement of the first protocol. The specific protocol type of the first protocol is set according to the actual scene requirements, and is not limited herein.

Similarly, the to-be-processed data of the first protocol described herein does not refer to only one piece of to-be-processed data, but may refer to multiple pieces of to-be-processed data.

The terminal sends the to-be-processed data of the first protocol to the electronic equipment, the electronic equipment converts the to-be-processed data of the first protocol into the to-be-processed data of the target protocol and sends the to-be-processed data of the target protocol to the control end, and the control end analyzes the to-be-processed data to determine whether equipment linkage is needed or not. When the equipment linkage is determined to be needed currently, the linkage data of the target protocol is issued, and then the electronic equipment carries out protocol conversion to obtain the corresponding linkage data of the second protocol so as to control the corresponding linkage equipment to carry out linkage control.

Details about this step will be described later.

And S12, performing protocol conversion on the to-be-processed data of the first protocol to obtain the to-be-processed data of the target protocol, and sending the to-be-processed data of the target protocol to the control end.

The target protocol is a protocol which can be directly processed by a subsequent control end, and the electronic equipment analyzes the data to be processed of the first protocol and encapsulates the data to be processed of the first protocol according to the format requirement of the target protocol, so that the data to be processed of the target protocol is obtained. As described above, the electronic device may perform conversion of multiple protocols, i.e., convert multiple protocols into a target protocol. The specific protocol type that the electronic device can process is set according to the requirements of the scene used by the electronic device, and is not limited herein.

After the to-be-processed data of the target protocol is obtained through protocol conversion, the electronic equipment sends the to-be-processed data of the target protocol to the control end, so that the control end can judge the to-be-processed data of the target protocol and determine whether the to-be-processed data of the target protocol is linkage data or not. For example, a linkage rule is set at the control end, and when the temperature of the equipment is more than 40 ℃, the ventilation equipment needs to be started to cool the equipment. If the data to be processed includes the equipment temperature, the control end analyzes the data to be processed of the target protocol to obtain the equipment temperature, for example, the equipment temperature is 40 ℃, and ventilation equipment needs to be started for linkage control when the temperature is higher than 40 ℃. Therefore, the linkage data are generated at the control end based on the data to be processed of the target protocol, the linkage data comprise the equipment type of the linkage equipment, so that the electronic equipment converts the linkage data of the target protocol into the linkage data of the protocol type corresponding to the linkage equipment, and linkage control is carried out on the linkage equipment.

Details about this step will be described later.

And S13, when the data to be processed is the equipment linkage data, receiving the linkage data of the target protocol fed back by the control end based on the data to be processed.

Wherein the linkage data includes a type of linkage device.

As described above, when the control end determines that the data to be processed needs linkage control of other devices, the control end issues linkage data, and accordingly, the electronic device receives linkage data of a target protocol fed back by the control end based on the data to be processed.

The linkage data is determined based on the data to be processed and the corresponding linkage rules; of course, the data to be processed may also include the type and the linkage mode of the linkage device, the control end analyzes the data to be processed to obtain the type and the linkage mode of the corresponding linkage device, and based on this, the control end generates the linkage data and issues the linkage data to the electronic device, so as to forward the linkage data by using the electronic device.

And S14, processing the linkage data based on the type of the linkage equipment to obtain linkage data of a second protocol.

The type of the linkage equipment corresponds to the protocol type of the linkage equipment, and after the type of the linkage equipment is determined, the protocol type of the linkage equipment can be correspondingly determined, so that protocol conversion processing is carried out on the linkage equipment, and linkage data of a second protocol are obtained. It should be noted here that the type of the linkage device may also correspond to a target protocol, and then, at this time, no protocol conversion is needed, and at this time, the second protocol is the target protocol.

It should be noted that, if there are multiple linkage devices and the types of the linkage devices are not all the same, there may be multiple second protocols, and in this case, the second protocol is only a protocol type different from the target protocol, and is not limited to only one protocol type, and may be a general name of multiple protocol types.

Details about this step will be described later.

And S15, sending the linkage data of the second protocol to the linkage equipment so as to carry out linkage control on the linkage equipment.

And the electronic equipment sends the linkage data of the second protocol to the linkage equipment based on the connection mode with the linkage equipment. The linkage device may be one or more, and the electronic device transmits the linkage data of the corresponding second protocol to the corresponding linkage device, so that the linkage device realizes linkage control by executing the linkage data.

According to the data transmission method provided by the embodiment, the received data to be processed is uniformly processed into the data to be processed of the target protocol for data transmission, conversion of the data among different protocols can be simplified, decision judgment is performed uniformly by using the data to be processed of the target protocol, when the data to be processed is determined to be the equipment linkage data, the linkage data is converted into the corresponding linkage data of the second protocol, message queues with different themes are not needed in the processing process, the data is uniformly processed after the protocol conversion, and the real-time performance of equipment linkage is improved.

In this embodiment, a data transmission method is provided, which can be used in the above-mentioned electronic device, such as a device gateway, etc., fig. 5 is a flowchart of the data transmission method according to the embodiment of the present invention, and as shown in fig. 5, the flowchart includes the following steps:

Please refer to S11 in fig. 4 for details, which are not described herein.

And S22, performing protocol conversion on the to-be-processed data of the first protocol to obtain the to-be-processed data of the target protocol, and sending the to-be-processed data of the target protocol to the control end.

Please refer to S12 in fig. 4 for details, which are not described herein.

And S23, when the data to be processed is the equipment linkage data, receiving the linkage data of the target protocol fed back by the control end based on the data to be processed.

Wherein the linkage data includes a type of linkage device.

Please refer to S13 in fig. 4 for details, which are not described herein.

And S24, processing the linkage data based on the type of the linkage equipment to obtain linkage data of a second protocol.

Specifically, S24 includes:

and S241, determining the protocol type corresponding to the linkage equipment based on the type of the linkage equipment.

The type of the linkage device and the protocol type have a corresponding relationship, and the corresponding relationship may be configured in the electronic device in advance, or may be acquired by the electronic device from the control end, and so on. After the electronic equipment acquires the type of the linkage equipment, the protocol type corresponding to the linkage equipment can be determined by inquiring the corresponding relation.

And after the protocol type is determined, comparing the protocol type with the target protocol, and if the protocol type is the same as the target protocol, the target protocol is the second protocol without protocol conversion.

And S242, when the protocol type is different from the target protocol, performing protocol conversion on the linkage data based on the first access service corresponding to the protocol type to obtain linkage data of a second protocol.

When the determined protocol type is different from the target protocol, the electronic device needs to convert the target protocol into a second protocol. Specifically, the electronic device performs protocol conversion on the linkage data by using a first access service corresponding to the determined protocol, where the first access service is used to implement mutual conversion between the target protocol and the second protocol. If the target protocol is converted into the second protocol, the first access service analyzes the target protocol to obtain the content of the linkage data in each field of the target protocol, and then encapsulates the content of each field according to the format requirement of the second protocol to obtain the linkage data of the second protocol.

In some embodiments, the S242 includes:

(1) and forwarding the linkage data to a target protocol proxy service corresponding to the first access service.

(2) And the target protocol proxy service forwards the linkage data to the first access service to encapsulate the linkage data to obtain linkage data of a second protocol.

The target protocol proxy service is used for forwarding the data of the target protocol, for example, for downlink data, the target protocol proxy service is used for sending the data of the target protocol issued by the control terminal to the corresponding first access service for protocol conversion; for the uplink data, the first access service performs protocol conversion on the uplink data and then forwards the uplink data to the target protocol proxy service, and the target protocol proxy service uploads the data after the protocol conversion to the control terminal.

The linkage data is forwarded through the target protocol proxy service, namely, the target protocol proxy service is utilized to carry out uniform forwarding management, so that higher cohesion is achieved, and the stability of the Internet of things platform applying the method is improved.

And S25, sending the linkage data of the second protocol to the linkage equipment so as to carry out linkage control on the linkage equipment.

Please refer to S15 in fig. 4 for details, which are not described herein.

According to the data transmission method provided by the embodiment, when the protocol type of the linkage equipment is different from the target protocol, protocol conversion is realized by means of the first access service, conversion between the target protocol and the second protocol is realized, configuration rules are not needed, and the data transmission efficiency is improved.

In some embodiments, the data transmission method further includes:

(1) and acquiring data to be transmitted.

(2) And processing based on the protocol corresponding to the data to be transmitted, and determining the data to be transmitted of the target protocol.

(3) And sending the data to be transmitted of the target protocols to corresponding message middleware based on the priority of the data to be transmitted of each target protocol so as to process the data to be transmitted.

For the electronic equipment, different message middleware is called to upload the received data to be transmitted according to different priorities. For example, message middleware with different transmission rates is selected, and for data with higher priority, the data is transmitted through the message middleware with higher transmission rate; and transmitting the data with the lowest priority through message middleware with a general transmission rate.

The electronic equipment utilizes the priority of the data to be transmitted to adapt the message middleware so as to transmit the data of each priority in time. The message middleware is used for forwarding data, so that large data concurrence of a control end can be avoided, and the throughput capacity of the equipment access service is improved; meanwhile, the data to be transmitted with different priorities are forwarded to the corresponding message middleware for processing the data to be transmitted with different priorities, so that differential processing of the data to be transmitted with different priorities can be ensured, and the real-time performance of data transmission is improved.

In this embodiment, a data transmission method is provided, which can be used in the above-mentioned electronic device, such as a device gateway, etc., fig. 6 is a flowchart of the data transmission method according to the embodiment of the present invention, and as shown in fig. 6, the flowchart includes the following steps:

and S31, acquiring the data to be processed of the first protocol.

Specifically, S31 includes:

s311, receiving a device authentication request of the first protocol sent by the target device.

The type of the transmission protocol of the target device is a first protocol, and before data interaction with the control end is carried out, the control end needs to carry out device authentication on the target device. Based on this, after the target device is powered on, the target device sends a device authentication request to the electronic device, and accordingly, the electronic device receives the device authentication request of the first protocol sent by the target device. The device authentication request carries information such as an identifier of the target device, and the specific content carried is set according to a logic requirement of actual device authentication, which is not limited herein.

S312, the protocol conversion is carried out on the equipment authentication request of the first protocol to obtain the equipment authentication request of the target protocol, and the equipment authentication request is sent to the control end.

As described above, the protocol type of the data that can be processed by the control end is the target protocol, and then the electronic device needs to perform protocol conversion on the device authentication request of the first protocol after receiving the device authentication request of the first protocol, and encapsulate the device authentication request of the target protocol. Specifically, a first access service of the electronic device performs protocol conversion on a device authentication request of a first protocol to obtain a device authentication request of a target protocol; and forwarding the equipment authentication request of the target protocol to a target protocol access service, wherein the target protocol access service sends the equipment authentication request of the target protocol to a control terminal.

After receiving the device authentication request of the target protocol, the control terminal analyzes the device authentication request to obtain the identifier of the target device and performs device authentication on the identifier.
