Specifically, the configuration page comprises an internet of things device configuration page, a cloud platform configuration page and a protocol conversion configuration page. The Internet of things equipment configuration page is used for configuring information such as an information model, connection setting and connection protocol of the Internet of things equipment; the cloud platform configuration page is used for configuring information such as connection settings and connection protocols of the cloud platform; the protocol conversion configuration page is used for configuring a data conversion protocol between the Internet of things device and the cloud platform.

The first configuration operation is related operation of the user for configuring the Internet of things gateway accessed to the Internet of things device through the Internet of things device configuration page. The first data format is used for characterizing a communication theme data format required by the Internet of things equipment.

The user configures information such as connection setting and connection protocol of the internet of things to the cloud platform through the cloud platform configuration page, and accordingly, the internet of things gateway can respond to second configuration operation of the user on the cloud platform configuration page and automatically generate a communication theme data format of the cloud platform according to configuration data generated by the second configuration operation.

It should be noted that, the information model of the cloud platform for the internet of things device is preconfigured in the cloud platform configuration page, and the internet of things gateway can automatically generate the communication theme data format of the cloud platform for the internet of things device by combining the preconfigured information model of the internet of things device.

S14, responding to a third configuration operation of the protocol conversion configuration page, and determining a target conversion rule between the Internet of things device and the cloud platform based on the third configuration operation.

The third configuration operation is an operation in which the user performs protocol conversion configuration through the protocol conversion configuration page. The target conversion rule is used to determine a source data format before conversion and a target data format after conversion.

The user configures the protocol conversion information through the protocol conversion configuration page, for example, adds a protocol conversion rule, selects the protocol conversion rule and the like, and accordingly, the internet of things gateway can respond to a third configuration operation of the user on the protocol conversion configuration page, determine a source protocol theme before conversion and a target protocol theme to be converted according to the third configuration operation, then determine a source data format according to the source protocol, and determine a target data format according to the target protocol theme.

S15, converting the first data format and the second data format based on the target conversion rule.

The internet of things determines a source data format and a target data format in the first data format and the second data format according to a target conversion rule, and performs data conversion by combining the mapping relation of the data elements in the first data format and the second data format. Taking the first data format as a source data format and the second data format as a target data format as an example, the internet of things gateway can convert the first data format into the second data format according to a target conversion rule by combining the mapping relation of the data elements in the first data format and the second data format.

According to the method, the code writing is replaced in a page configuration mode, the access of the Internet of things equipment and the cloud platform can be realized without writing software and hardware codes, the workload is increased due to the fact that a large amount of embedded codes are written, the access difficulty and workload of various Internet of things equipment or a plurality of cloud platforms are reduced, the access efficiency is improved, the access safety and standardization of the Internet of things equipment and the cloud platforms are ensured, and the access effect of the Internet of things is improved.

In this embodiment, a protocol conversion method is provided, which may be used in a gateway, such as an internet of things gateway, and fig. 2 is a flowchart of the protocol conversion method according to an embodiment of the present invention, as shown in fig. 2, where the flowchart includes the following steps:

s21, acquiring a configuration page of the Internet of things gateway, wherein the configuration page of the Internet of things gateway comprises an Internet of things device configuration page, a cloud platform configuration page and a protocol conversion configuration page.

The detailed description refers to the corresponding related descriptions of the above embodiments, and will not be repeated here.

S22, responding to a first configuration operation of the configuration page of the Internet of things device, and determining a first data format of the Internet of things device based on the first configuration operation.

S23, responding to a second configuration operation of the cloud platform configuration page, and determining a second data format of the cloud platform based on the second configuration operation.

And S24, responding to a third configuration operation of the protocol conversion configuration page, and determining a target conversion rule between the Internet of things device and the cloud platform based on the third configuration operation.

S25, converting the first data format and the second data format based on the target conversion rule.

Specifically, the step S25 may include:

s251, determining a source data format and a target data format from the first data format and the second data format based on the target conversion rule.

The source data format is the data format before conversion and the target data format is the data format after conversion. The internet of things gateway can determine whether the internet of things device sends data to the cloud platform or whether the cloud platform sends data to the internet of things device currently according to the target conversion rule.

For example, when the internet of things device sends data to the cloud platform, the first data format determined by the internet of things device based on the message protocol theme is used as a source data format, and the second data format determined by the cloud platform based on the message protocol theme is used as a target data format. Taking fig. 3 as an example, the source message protocol is a modbus protocol, the source message topic is attribute reporting, the target message protocol is a platform protocol, and the target message topic is equipment reporting attribute. For the source message protocol and the target message protocol, corresponding protocol information is respectively corresponding, and for different protocol information, corresponding data formats are corresponding, as shown in fig. 4.

S252, respectively extracting a first data element in the source data format and a second data element in the target data format.

The first data element is all leaf nodes contained in the source data format. The second data element is all leaf nodes contained in the target data format. The internet of things gateway can analyze the data elements contained in the source data format according to the message protocol for generating the source data format, and similarly, can analyze the data elements contained in the target data format according to the message protocol for generating the target data format.

Taking the human body sensor as an example, the first data element and the second data element may include elements such as human body existence signal, delay, sensitivity, and the like, and the first data element and the second data element obtained by analyzing the elements are displayed in a protocol conversion configuration page by the internet of things gateway, as shown in fig. 5.

S253, determining a mapping relationship between the first data element and the second data element.

And constructing a mapping relation between the first data element and the second data element according to the association degree between the first data element and the second data element. The association degree can be determined by a connection method, can also be determined by comparing semantic information, can be determined by comparing keywords, is not particularly limited herein, and can be determined by a person skilled in the art according to actual needs.

As an alternative embodiment, the mapping relationship between the data elements may be determined here by means of a wire, in particular:

(1) In response to a join operation on the first data element and the second data element, a join relationship between the first data element and the second data element is determined based on the join operation.

(2) A mapping relationship between the first data element and the second data element is determined based on the connection relationship.

The user connects the first data element and the second data element correspondingly on the protocol conversion configuration page through the input device such as the keyboard or the mouse, and correspondingly, the internet of things gateway can respond to the connection operation of the user on the first data element and the second data element on the protocol conversion configuration page to obtain the connection relation between the first data element and the second data element, and a corresponding connection line is generated between the first data element and the second data element, as shown in fig. 5.

The internet of things automatically generates a corresponding data mapping relation according to the connection line between the first data element and the second data element, as shown in fig. 6.

Through connecting lines between the first data elements and the second data elements, the mapping relation between the first data elements and the second data elements can be determined according to the connection relation, so that the data elements to be converted automatically generate the data mapping relation in a connection mode, and a user does not need to write protocol conversion codes.

And S254, converting the source data format into a target data format based on the mapping relation.

The mapping relationship can characterize differences between the source data format and the target data format, such as element identification, differences between element types. The internet of things gateway can map the data elements in the source data format to the target data format according to the mapping relation.

As shown in fig. 6, the source data format and the target data format are different in element identifiers and correspond to corresponding aliases, and at this time, the internet of things gateway can map the data elements in the source data format to the target data format according to the alias mapping relationship.

According to the protocol conversion method provided by the embodiment, the mapping relation between the data elements is determined by extracting the data elements in the source data format and the target data format, and then the conversion from the source data format to the target data format is completed according to the mapping relation. Therefore, the conversion of the data format can be realized through the target conversion rule of the visual page configuration, and the data conversion can be realized without encoding.

In this embodiment, a protocol conversion method is provided, which may be used in a gateway, such as an internet of things gateway, and fig. 7 is a flowchart of the protocol conversion method according to an embodiment of the present invention, as shown in fig. 7, where the flowchart includes the following steps:

S32, responding to a first configuration operation of the configuration page of the Internet of things device, and determining a first data format of the Internet of things device based on the first configuration operation.

Specifically, the step S32 may include:

s321, determining measurement point information of the Internet of things device and a first communication connection protocol based on the first configuration operation.

The measuring point information is used for characterizing a target point when the Internet of things equipment is observed. The first communication connection protocol is a communication protocol and a connection protocol when the Internet of things equipment is accessed to the Internet of things gateway.

The communication protocols of different Internet of things equipment when being accessed to the Internet of things gateway are different, and corresponding setting contents are different. Specifically, the setting content of the communication protocol includes: serial port/network port information, equipment addresses, data acquisition modes and the like.

For the internet of things device, the connection protocol is configured as a southbound connection protocol, and the configuration content of the connection protocol includes: connection protocol basic information, communication subject data format, and the like.

Taking the internet of things equipment as a human body sensor, and configuring the human body sensor in the internet of things gateway as an example, the specific configuration implementation mode is as follows:

the user can configure basic attributes (such as equipment names, equipment identifiers and the like), inherent attributes (such as models, brands and the like) and measurement point information (such as human body presence signals, time delay, sensitivity and the like) of the human body sensor in the Internet of things equipment configuration page.

Correspondingly, the internet of things gateway can respond to the configuration operation of the user on the internet of things device configuration page, generate measurement point configuration data corresponding to the configuration operation, and display the basic attribute, the inherent attribute, the measurement point information and the like of the completion of the configuration on the internet of things device configuration page, as shown in fig. 8.

The user can configure the communication protocol of the human body sensor in the configuration page of the internet of things equipment, and set the connection content of the communication protocol. The specific connection setting content comprises equipment addresses, communication protocols, serial numbers, baud rates, acquisition rules and the like.

Accordingly, the internet of things gateway can respond to the configuration operation of the user on the internet of things device configuration page, generate the communication protocol configuration data corresponding to the configuration operation, and display the communication protocol content after the configuration on the internet of things device configuration page, as shown in fig. 9.

The user can configure the connection protocol of the human body sensor in the configuration page of the internet of things device, set the basic information of the connection protocol, the data format of the communication theme (such as theme name, communication protocol and data format) and the like in the connection protocol in combination with the communication protocol (such as modbus protocol), and configure the connection protocol as a southbound connection protocol.

Correspondingly, the internet of things gateway can respond to the configuration operation of the user on the internet of things device configuration page, generate connection protocol configuration data corresponding to the configuration operation, and display connection protocol content with completed configuration on the internet of things device configuration page, as shown in fig. 10.

S322, according to the first communication connection protocol and the measuring point information, a first data format of the Internet of things equipment is generated.

After the internet of things gateway completes configuration of the connection protocol according to configuration operation, a communication theme data format is automatically generated based on the connection protocol, the communication protocol of the internet of things device and the configured measurement point information of the internet of things device, and all leaf nodes contained in the communication theme data format are automatically analyzed to serve as data elements.

Taking the internet of things equipment as a human body sensor, for example, the human body sensor is configured in the gateway of the internet of things, and the gateway of the internet of things automatically generates a communication subject data format based on a connection protocol, a communication protocol (such as a modbus protocol) of the human body sensor, and configured measurement point information such as human body presence signals, time delay, sensitivity and the like, as shown in fig. 11.

S33, responding to a second configuration operation of the cloud platform configuration page, and determining a second data format of the cloud platform based on the second configuration operation.

Specifically, the step S33 may include:

s331, obtaining preset model information of the cloud platform aiming at the Internet of things equipment.

The preset model information is an information model which is preset in the cloud platform and aims at each piece of internet of things equipment, and is generated in the form of JSON files. When the cloud platform is configured in the internet of things gateway, the cloud platform is accessed through a preset communication protocol (such as an MQTT protocol), and after the cloud platform is accessed, an information model configured in the cloud platform can be searched to determine preset model information corresponding to the internet of things device.

It should be noted that, if the search mode of the information model of the internet of things device of the accessed internet of things gateway is not currently provided in the cloud platform, the user may obtain the model information of the internet of things device through other ways (for example, modes of HTTP or manual derivation, etc.), and create the information model of the internet of things device in the cloud platform configuration page.

S332, extracting preset measuring point information of the Internet of things equipment from the preset model information.

The preset measuring point information is an observed target point which is preconfigured by the cloud platform and aims at the internet of things equipment. The preset model information comprises equipment basic information, inherent attributes, measuring point information and the like corresponding to the internet of things equipment, and the internet of things gateway can analyze the acquired preset model information and extract preset measuring point information aiming at the internet of things equipment.

S333, determining a second communication connection protocol of the cloud platform based on the second configuration operation.

The second communication connection protocol is a communication protocol and a connection protocol when the Internet of things is connected with the cloud platform. The communication protocols of the internet of things-based access cloud platform are different, and different setting contents exist. Taking the MQTT protocol as an example, the connection setting contents of the communication protocol include: host address Host, port, client ID, etc.

For the cloud platform, the connection protocol of the internet of things access to the cloud platform is configured as a northbound connection protocol, and the configuration content of the connection protocol comprises: connection protocol basic information, communication theme message routing, communication theme data format and the like.

Specifically, the user can perform relevant configuration on the connection setting of the access cloud platform in the cloud platform configuration page. Correspondingly, the internet of things gateway can respond to the configuration operation of the user on the cloud platform configuration page, generate configuration data corresponding to the configuration operation, and display connection setting content and the like after the configuration is completed on the cloud platform configuration page, as shown in fig. 12.

The user can configure a connection protocol of the internet of things for accessing the cloud platform in the cloud platform configuration page, set the basic information of the connection protocol required by the cloud platform, the communication subject message route (such as a subject path), the communication subject data format and the like, and configure the connection protocol as a northbound connection protocol.

Correspondingly, the internet of things gateway can respond to the configuration operation of the user on the cloud platform configuration page, generate connection protocol configuration data corresponding to the configuration operation, and display connection protocol contents such as a communication theme list, a communication theme path and the like after the configuration is completed on the cloud platform configuration page, as shown in fig. 13.

And S334, generating a second data format of the cloud platform according to the second communication connection protocol and the preset measurement point information.

After the internet of things gateway completes the configuration of the connection protocol for the cloud platform according to the configuration operation, a required communication theme data format is automatically generated based on the connection protocol and preset measurement point information of the internet of things device, and all leaf nodes contained in the communication theme data format are automatically analyzed to serve as data elements.

Taking the internet of things device as a human body sensor as an example, when the cloud platform is configured in the internet of things gateway, the internet of things gateway automatically generates a communication theme data format based on a connection protocol and preset point information which is configured in advance and aims at the human body sensor, as shown in fig. 14.

And S34, responding to a third configuration operation of the protocol conversion configuration page, and determining a target conversion rule between the Internet of things device and the cloud platform based on the third configuration operation.

Specifically, the step S34 may include:

s341, responding to the editing operation of the conversion rules, and generating at least one conversion rule based on the editing operation.

The conversion rule is a rule for converting a data format between the internet of things device and the cloud platform, and specifically comprises the following steps: the internet of things device sends data to the cloud platform to perform data format conversion rules, and the cloud platform sends data to the internet of things device to perform data format conversion rules, such as conversion rules between a platform protocol of the cloud platform and a modbus protocol of the internet of things device shown in fig. 15.

Specifically, the user edits the theme conversion rules at the protocol conversion configuration page to determine the operation of the source protocol theme and the target protocol theme of the conversion rules. Accordingly, the Internet of things gateway can respond to editing operation of a user on the protocol conversion configuration page, and one or more conversion rules are generated according to the editing operation.

S342, in response to a selection operation of at least one conversion rule, determining a target conversion rule based on the selection operation.

The user selects the currently required data conversion rule from the conversion rules through the input device such as a keyboard or a mouse, and correspondingly, the internet of things gateway can respond to the selection operation of the user, determine the conversion rule selected by the user as the target conversion rule, and determine the source protocol theme before conversion and the target protocol theme after conversion based on the target conversion rule, as shown in fig. 3.

S35, converting the first data format and the second data format based on the target conversion rule.

S36, in response to the export operation of the configuration information, exporting the configuration information of the Internet of things device corresponding to the first configuration operation, the configuration information of the cloud platform corresponding to the second configuration operation and the protocol conversion configuration information corresponding to the third configuration operation based on the export operation.

When the same Internet of things equipment is accessed in other Internet of things, the current configuration information can be multiplexed into other gateways at the moment, so that repeated configuration for the same Internet of things equipment can be avoided. When the current or other Internet of things are connected with the same type of Internet of things equipment, the current configuration information can be copied into new configuration information for use, and the new same type of Internet of things equipment can be quickly connected only by modifying different few configurations among the Internet of things equipment, so that repeated configuration of the same type of Internet of things equipment can be avoided. Specifically, a configuration page of the internet of things gateway is provided with a export tag, and after the configuration of the internet of things device, the cloud platform and the protocol conversion is completed, a user can export the configuration information of the internet of things device, the configuration information of the cloud platform and the configuration information of the protocol conversion through the export tag. Correspondingly, the Internet of things gateway can respond to the export operation to obtain Internet of things equipment configuration information, cloud platform configuration information and protocol conversion configuration information.

It should be noted that, corresponding export tags may be respectively set on the configuration page of the internet of things device, the configuration page of the cloud platform, and the configuration page of the protocol conversion, and if a user wants to export certain configuration information, the user may perform export operation of the configuration information through the export tag on the corresponding configuration page. Correspondingly, the internet of things gateway can respond to the export operation to export the configuration information of the internet of things device, or the configuration information of the cloud platform, or the configuration information of the protocol conversion.

According to the protocol conversion method provided by the embodiment, the measurement point information and the communication connection protocol of the Internet of things device are configured in a visual configuration page mode, and the cloud platform communication connection protocol is configured in a visual configuration page mode, so that the automatic generation of the data format of the Internet of things device and the automatic generation of the data format of the cloud platform aiming at the Internet of things device are realized in a page configuration mode, real-time adjustment according to actual needs is facilitated, code writing or uploading of a coding and decoding component is not needed, and the code writing requirements for technicians are greatly reduced. The protocol conversion between the Internet of things equipment and the cloud platform is configured in a visual configuration page mode, and then a corresponding target conversion rule is determined from the configured protocol conversion rule, so that flexible configuration and flexible use of the conversion rule are realized. Meanwhile, the configuration information can be exported in a supported manner, so that the configuration information can be conveniently multiplexed in other gateways, repeated configuration is not needed, and configuration time is saved.

In this embodiment, a data transmission method is provided, which may be used in a gateway, such as an internet of things gateway, and fig. 16 is a flowchart of a data transmission method according to an embodiment of the present invention, as shown in fig. 16, where the flowchart includes the following steps:

s41, acquiring data to be transmitted.

The data to be transmitted comprises data uploaded to the cloud platform by the internet of things device and/or data issued to the internet of things device by the cloud platform.

When the data to be transmitted is the data uploaded to the cloud platform by the internet of things equipment, the data to be transmitted is the data acquired by the internet of things from the internet of things equipment. Taking a human body sensor as an example, the data to be transmitted is data collected from the human body sensor at regular intervals by the internet of things, for example, the data collected at a certain moment is: the human body has the functions of signal, time delay and sensitivity.

When the data to be transmitted is the data issued by the cloud platform to the Internet of things equipment, the data to be transmitted is the data issued by the cloud platform monitored by the Internet of things gateway. Taking a human body sensor as an example, the data to be transmitted are delay data, sensitivity data and the like which are required to be issued to the human body sensor and are monitored by the internet of things gateway from the cloud platform.

S42, carrying out protocol conversion on the data to be transmitted based on a protocol conversion method, and converting the data to be transmitted into a target data format which can be identified by target equipment.

The target equipment is Internet of things equipment or a cloud platform.

The protocol conversion method according to the above embodiment performs protocol conversion on the data to be transmitted, so as to convert the data format of the data to be transmitted into a target data format that can be identified by the target device. Specifically, the protocol conversion includes conversion from the internet of things device to the cloud platform and conversion from the cloud platform to the internet of things device. These two conversion modes will be described below, respectively.

(1) And converting the Internet of things equipment into a cloud platform.

The internet of things automatically codes and decodes the data of the internet of things according to the information model and the connection protocol of the configured internet of things equipment, generates a corresponding data format of the internet of things equipment, and converts the data format of the internet of things equipment into a data format recognized by the cloud platform according to the protocol conversion rule between the configured internet of things equipment and the cloud platform.

Taking the internet of things equipment as a human body sensor, the data to be transmitted is measurement point information such as human body existence signal, time delay, sensitivity and the like, and the communication protocol is modbus as an example, the internet of things gateway can generate a data format of a corresponding communication theme from the data acquired by the internet of things gateway from the human body sensor according to configuration information:

{

"bodySignal": 1,

"delayTime": 25,

"sensitivity": 5

}；

Then, according to the configured protocol conversion rule, converting the communication theme data of the human body sensor into a data format required by the cloud platform:

{

"id": "0000001",

"time": "2022-10-2810:10:10",

"type": "info",

"data": {

"body_signal": 1,

"delay_time": 25,

"sensitivity": 5

}

}。

(2) And converting the cloud platform into the Internet of things equipment.

The internet of things is connected to the cloud platform according to the connection setting of the configured cloud platform, monitors and receives data sent by the cloud platform to the internet of things device according to the connection protocol of the configured cloud platform, and then converts a data format of the data sent by the cloud platform to the internet of things device into a data format recognized by the internet of things device according to a protocol conversion rule between the configured internet of things device and the cloud platform.

Taking the connection protocol of the internet of things to the cloud platform as an MQTT protocol as an example, the internet of things gateway can monitor and receive data sent by the cloud platform to the internet of things device according to the configured cloud platform connection protocol, for example, the monitored MQTT path is: the data format of the corresponding communication theme is generated by the data sent to the internet of things device from the cloud platform acquired from the path:

{

"id": "0000002",

"time": "2022-10-2811:11:11",

"mode": "sync",

"data": {

"delay_time": 30,

"sensitivity": 3

}

}；

then, according to the configured protocol conversion rule, converting the communication theme data of the cloud platform into a data format recognized by the internet of things device:

{

"delayTime": 30,

"sensitivity": 3

}。

S43, sending the data to be transmitted in the target data format to the target equipment.

If the data to be transmitted is the data uploaded to the cloud platform by the Internet of things device, the Internet of things device accesses the cloud platform according to the connection configuration of the configured cloud platform, and sends the data to be transmitted in the target data format obtained after conversion to the cloud platform. For example, according to the configured communication connection protocol of the cloud platform, the internet of things sends the data to be transmitted in the target data format obtained after conversion to the MQTT path corresponding to the cloud platform: sys/body_sensor/device_001/ting/event/property/post.

If the data to be transmitted is the data issued to the Internet of things equipment by the cloud platform, the Internet of things gateway connects the Internet of things equipment according to the connection configuration of the configured Internet of things equipment, and the data to be transmitted in the target data format obtained after conversion is sent to the Internet of things equipment. For example, the internet of things sends the data to be transmitted in the target data format obtained after conversion to the human body sensor according to the communication connection protocol of the human body sensor which is configured.

According to the data transmission method, the data to be transmitted is subjected to protocol conversion to be converted into the target data format which can be identified by the target equipment, so that the target equipment can accurately receive the data, and the data transmission efficiency is improved.
