For convenience of description, some terms or expressions referred to in the embodiments of the present application are explained below:

communication protocol (Communications protocol): refers to the rules and conventions that must be followed by two entities to complete a communication or service. In computer communication, a communication protocol is used for realizing a standard between a computer and a network connection, and if the network does not have a uniform communication protocol, information transmission between the computers cannot be identified. The communication protocol refers to a communication rule predetermined in advance by the communicating parties.

Data protocol: refers to the format of data for both entities to complete data interaction.

As mentioned in the background of the invention, in order to solve the above problem, the prior art has poor flexibility in data processing, and in an exemplary embodiment of the present application, a data processing method, an analysis service, a computer-readable storage medium, and an internet of things platform are provided.

According to an embodiment of the present application, a method of processing data is provided.

Fig. 1 is a flowchart of a data processing method according to an embodiment of the present application. The processing method is applied in a resolution service (a server), the resolution service communicates with a plurality of target gateways, one target gateway communicates with at least one communication module, and one communication module connects to at least one IoT terminal, as shown in fig. 1, the processing method includes the following steps:

step S101, determining a target protocol of the data packet when the received data packet sent by the target gateway is an uplink data packet, where the target protocol includes at least one of the following: a communication protocol and a data protocol, wherein the data protocol is a protocol describing data of the IoT terminal;

step S102, determining a corresponding target coding and decoding processor at least according to the target protocol of the data packet, wherein the target coding and decoding processor is used for carrying out format conversion on the corresponding data packet;

step S103, at least according to the target coding and decoding processor, carrying out format conversion on the data packet to obtain target data.

In the above data processing method, first, after receiving a data packet sent by a target gateway, it is determined whether the received data packet is an uplink data packet, and if the data packet is the uplink data packet, a target protocol of the data packet, that is, a communication protocol and a data protocol of the data packet, is determined; then, determining a corresponding target coding and decoding processor at least according to the target protocol of the data packet, namely the communication protocol and/or the data protocol; and finally, performing format conversion on the data packet at least according to the target coding and decoding processor to obtain target data, namely converting the data packet into a data format which can be read by a service. According to the data processing method, the protocol used by the data packet is regarded as any nesting of the communication protocol and the data protocol, the communication protocol and the data protocol of the data packet are determined under the condition that the received data packet is an uplink data packet, the corresponding target coding and decoding processor is determined according to the communication protocol and/or the data protocol of the data packet, and format conversion is performed on the corresponding data packet at least according to the target coding and decoding processor to obtain target data, so that format conversion is performed on effective data carried by the data packet more simply. That is to say, the processing method of the present application can determine the corresponding target codec processor to implement format conversion on the data packet under the condition of knowing the communication protocol and the data protocol corresponding to the data packet, so that the processing method of the present application can process any type of data packet, implement more flexible and more reliable processing on data, and solve the problem of poor flexibility of data processing in the prior art.

Specifically, the data transmission process of the uplink data packet (which may also be referred to as an upload data packet) is as follows: the IoT terminal sends an initial data packet (the initial data packet does not carry a communication protocol at the moment) to the communication module; the communication module carries out protocol encapsulation on the received initial data packet based on a communication protocol of the communication module to obtain a preset data packet, and sends the preset data packet to a corresponding target gateway. And when the target gateway receives a preset data packet sent by the communication module, adding a channel unique identifier and a module identifier to the preset data packet to obtain the data packet. The target gateway puts the data packet into a message queue (such as an MQ message queue), and waits until the analysis service consumption is reached, so as to perform format conversion on the data packet to obtain target data. In an actual application process, the analytic service is sent to the target gateway, and then the target gateway sends the analytic service to the communication module, so that a data packet sent to the IoT terminal may be referred to as a downlink data packet (or may also be referred to as an issued data packet).

Specifically, the data packet may also be a data packet obtained after the destination gateway performs packet processing on the data stream or the datagram sent by the communication module. After the target gateway receives the data packet, the target gateway sends the data packet to the resolution service. Under the condition that the target gateway has the identity authentication function, the target gateway can also perform identity authentication on a data packet, so that the data packet subsequently sent to the analysis service can carry a channel unique identifier (namely, a global unique identifier of the Socket). Of course, the unique identifier of the gateway message, the data type of the data packet, the original data encoding format, the communication data (packet/frame), the communication time, and the extension data (for example, the IP (Internet Protocol Address, IP for short) Address of the source of the data packet, the service level, the will order, etc.) may also be carried.

In a specific embodiment of the present application, the number of target codec processors for performing format conversion on one data packet may be one, or may be multiple. That is, when the format of the packet is converted, the number of target codec processors used may be determined according to the data of the valid data portion in the packet. For example, for a data packet, in the valid data of the data packet, the first byte carries a temperature value, a target codec processor may be used to perform format conversion on the first byte to obtain a format-converted temperature value; if the second byte to the fifth byte in the valid data carry failure information, another target codec processor may be used to perform format conversion on the second byte to the fifth byte, so as to obtain failure information after format conversion. Of course, in practical application, the target codec processor may also be adjusted and set according to the data type, coding format, and the like of the valid data in the data packet, and is not limited to the target codec processor mentioned in the above example.

In an actual application process, a communication protocol is added to the received initial data packet of the IoT terminal at the communication module, so as to obtain a preset data packet. After the communication module sends the preset data packet to the target gateway in the form of data stream or datagram, the target gateway needs to perform packet-packet processing on the received data stream or datagram to convert the data stream or datagram into an independent data packet. For a packet, it is essentially a separate packet or frame of data. Which may carry a data packet header, a data packet payload, and a data packet checksum or data packet trailer, among other things. In the processing method, the protocol used by the data packet is divided into a communication protocol and a data protocol, so that the data packet received by the target gateway is the communication protocol of unlimited level and the nesting of the data protocol. Specifically, as shown in fig. 2, for example, a data packet 100 includes a communication protocol header 101 and a communication protocol payload 104, and the communication protocol payload 104 includes an embedded data protocol portion 102 and a check tail 103. As shown in fig. 3, the communication protocol payload 104 may further include a first data protocol 105, a first data payload 111, and a transmission check tail 110 (in an actual application, the communication protocol payload 104 may further not include the transmission check tail 110), and for the first data payload 111, the first transmission data 106 and the second transmission data 107 may be embedded inside, and the sub-protocol 108 and the sub-protocol data 109 (i.e., a valid data portion of the sub-protocol) may be embedded inside. As shown in fig. 4, the communication protocol payload 104 may further include a second data protocol 112 and a second data payload 113, wherein the second data payload 113 may further embed the plurality of transmission data.

It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than here.

In an embodiment of the present application, the determining a target protocol of the data packet when the received data packet sent by the target gateway is an uplink data packet includes: determining the target protocol based on the channel unique identifier of the data packet, if the corresponding target protocol can be determined based on the channel unique identifier of the data packet; and under the condition that the corresponding target protocol cannot be determined based on the channel unique identifier of the data packet, determining the target protocol of the data packet at least according to the module identifier carried by the data packet, so that the analysis service can determine the communication protocol and the data protocol of the data packet relatively simply, and the calculation amount of the analysis service is relatively small.

In order to determine a communication protocol and a data protocol used by a data packet more simply, in another embodiment of the present application, determining the target protocol of the data packet at least according to the module identifier carried by the data packet includes: determining the communication protocol according to the module identifier of the data packet; searching a corresponding product identifier in a communication module table according to the module identifier of the data packet, wherein the communication module table at least comprises the module identifier and a product identifier, and the product identifier is an identifier of a product formed by the communication protocol and the data protocol; and determining the data protocol of the corresponding data packet according to the communication protocol and the product identifier. That is to say, according to the module identifier of the target gateway, the outer layer communication protocol of the data packet can be obtained, then the product identifier corresponding to the communication protocol is obtained based on the pre-stored communication module table, the data protocol corresponding to the data packet is obtained, and the data protocol and the communication protocol corresponding to the data packet are further determined relatively simply and accurately.

Specifically, in the actual application process, the communication module table is preset in the parsing service. The communication module table has a module identification column, a product identification column and a communication protocol identification column. Wherein the product identification column has a plurality of products therein. The products are composed of different communication protocols and data protocols. In a specific embodiment of the present application, communication protocol a and data protocol a constitute one product, communication protocol a and data protocol B constitute another product, and so on.

In order to determine a target codec processor corresponding to a data packet more simply, in another embodiment of the present application, determining a corresponding target codec processor at least according to the target protocol of the data packet includes: under the condition that an encoding and decoding processor corresponding to the data packet is found in a protocol item table according to a protocol identifier, determining the found encoding and decoding processor as the corresponding target encoding and decoding processor, wherein the protocol identifier is the identifier of the target protocol of the data packet, and the protocol item table at least comprises the protocol identifier and the encoding and decoding processor corresponding to the protocol identifier; and if the protocol identifier does not find the codec processor corresponding to the data packet in the protocol entry table, determining a preset codec processor as the corresponding target codec processor, so that the processing method of the present application can perform preliminary processing on data by using the preset codec processor even without knowing the communication protocol and the data protocol corresponding to the data packet.

In a specific embodiment of the present application, the protocol entry table may further include a protocol entry identifier, a data index, a data type, and an extension data segment. The data types include integers, floating point numbers, character strings, subprotocol types, function code types and the like. The extension data segment can store corresponding required information in cooperation with the data type, for example, when the data type is a sub-protocol type mark, the protocol identifier of the sub-protocol is stored in the extension data segment.

Specifically, in the actual application process, the product table, the protocol table, and the device table may also be prestored in the server. The product table comprises a product identification column, a communication protocol identification column and a data protocol identification. The protocol table includes a protocol identification column, a protocol type column and a protocol device type column. The device table includes a device identifier column, a product identifier column, and a data protocol identifier column.

In another embodiment of the present application, the processing method further includes: and determining a preset coding and decoding processor as the corresponding target coding and decoding processor under the condition that the target protocol of the data packet is not determined at least according to the module identifier of the target gateway carried by the data packet. In this embodiment, when the communication protocol and the data protocol of the data packet cannot be determined, the preset codec processor is used to determine the target codec processor for the data packet, so that the processing method of the present application can perform preliminary processing on data by using the preset codec processor even without knowing the communication protocol and the data protocol corresponding to the data packet, thereby further ensuring that the processing method of the present application can perform format conversion on the data packet more flexibly.

In order to further obtain the target data more accurately, in another embodiment of the present application, performing format conversion on the data packet at least according to the target codec processor to obtain the target data includes: and performing format conversion on the corresponding data packet according to the target coding and decoding processor and a corresponding data item of the target protocol to obtain the target data, wherein the data item is used for marking the position of a transmission value of the communication protocol or the data protocol.

In a specific embodiment of the present application, for the communication protocol portion of the data packet and the valid data portion of the data protocol, the data items thereof can be described in the following forms: 1. offsetting n bytes, wherein the length is m bytes, the byte order is large end (namely high address)/small end (namely low address), and the byte order is the transmission value of the data item; 2. offsetting n bytes, offsetting the mth bit, wherein the byte order is big end/small end and is the transmission value of the data item; 3. offsetting n bytes, offsetting the mth bit, having a total length of k bits, wherein the byte order is a big end/a small end and is a transmission value of a data item; 4. a data item for which a field name (e.g., JSON) matches, is a transfer value of the data item; 5. the nth element (which can be bit, byte, word, or character string separated by fixed format), the byte order is big end/small end, and is the transmission value of the data item; 6. the nth element (which can be bit, byte, word, or character string separated by fixed format) is m elements long, and the byte order is the transmission value of the data item at the big end/small end; 7. numbering the nth element (which can be bit, byte, word, or character string separated by fixed format), wherein the byte order is big end/small end and is the transmission value of the data item; 8. the nth element (which may be a bit, a byte, a Word, or a string separated in a fixed format) is numbered, the nth element is m long, and the endian is a transmission value of the data item at the big end/the small end. After the actual transmission value is obtained, the coding and decoding processor appointed by the data packet is matched with the relevant parameter of the transmission value in the data item, and the transmission value is converted into the general data type (shaping, floating point number, character string, enumeration character string and the like) which can be directly used in the system.

Because the data packet is regarded as an unlimited level communication protocol and the nesting of the data protocol, the data packet can also be an embedded protocol. In order to further obtain the target data more accurately, in an embodiment of the application, after performing format conversion on the corresponding data packet according to the target codec processor and the corresponding data item of the target protocol to obtain the target data, the processing method further includes: determining whether a sub-protocol identifier exists in the data packet, wherein the sub-protocol identifier is the protocol identifier of a sub-protocol, and the sub-protocol is the communication protocol or the data protocol; determining whether to find the corresponding codec processor in a protocol entry table based on the sub-protocol identifier if the sub-protocol identifier exists in the data packet, where the protocol entry table at least includes the protocol identifier and the codec processor corresponding to the protocol identifier; determining the codec processor as the target codec processor of the corresponding data packet if the corresponding codec processor is found in the protocol entry table based on the sub-protocol identifier, and determining a preset codec processor as the target codec processor of the corresponding data packet if the corresponding codec processor is not found in the protocol entry table based on the sub-protocol identifier; and carrying out format conversion on the data packet based on the target coding and decoding processor to obtain corresponding target data.

In a specific embodiment of the present application, after determining the preset codec processor as the target codec processor and performing format conversion on the corresponding data packet by using the target codec processor, the processing method of the present application may further include: and updating the communication protocol and the data protocol corresponding to the data packet and the corresponding target coding and decoding processor in a protocol entry table so as to facilitate format conversion of the data packet subsequently.

The embodiment of the present application further provides an analysis service, and it should be noted that the analysis service of the embodiment of the present application may be used to execute the processing method for data provided in the embodiment of the present application. The following describes a resolution service provided in an embodiment of the present application.

Fig. 5 is a schematic structural diagram of a resolution service according to an embodiment of the present application. As shown in fig. 5, the resolution service communicates with a plurality of target gateways, one of the target gateways communicates with at least one communication module, and one of the communication modules connects to at least one IoT terminal, and the resolution service includes:

a first determining unit 10, configured to determine a target protocol of a received data packet sent by the target gateway, where the target protocol includes at least one of the following: a communication protocol and a data protocol, wherein the data protocol is a protocol describing data of the IoT terminal;

a second determining unit 20, configured to determine a corresponding target codec processor according to at least the target protocol of the data packet, where the target codec processor is configured to perform format conversion on the corresponding data packet;

a first conversion unit 30, configured to perform format conversion on the data packet at least according to the target codec processor, so as to obtain target data.

In the analysis service, after receiving a data packet sent by a target gateway, a first determining unit determines whether the received data packet is an uplink data packet, and if the data packet is the uplink data packet, determines a target protocol of the data packet, that is, determines a communication protocol and a data protocol of the data packet; the second determining unit is used for determining a corresponding target coding and decoding processor at least according to a target protocol of the data packet, namely the communication protocol and/or the data protocol; the first conversion unit is used for performing format conversion on the data packet at least according to the target coding and decoding processor to obtain target data, namely converting the data packet into a data format which can be read by service. According to the data processing method, the protocol used by the data packet is regarded as any nesting of the communication protocol and the data protocol, the communication protocol and the data protocol of the data packet are determined under the condition that the received data packet is an uplink data packet, the corresponding target coding and decoding processor is determined according to the communication protocol and/or the data protocol of the data packet, and format conversion is performed on the corresponding data packet at least according to the target coding and decoding processor to obtain target data, so that format conversion is performed on effective data carried by the data packet more simply. That is to say, the processing method of the present application can determine the corresponding target codec processor to implement format conversion on the data packet under the condition of knowing the communication protocol and the data protocol corresponding to the data packet, so that the processing method of the present application can process any type of data packet, implement more flexible and more reliable processing on data, and solve the problem of poor flexibility of data processing in the prior art.

Specifically, the data transmission process of the uplink data packet (which may also be referred to as an upload data packet) is as follows: the IoT terminal sends an initial data packet (the initial data packet does not carry a communication protocol at the moment) to the communication module; the communication module performs protocol encapsulation on the received initial data packet based on a communication protocol of the communication module to obtain a preset data packet, and sends the preset data packet to a corresponding target gateway. And when the target gateway receives a preset data packet sent by the communication module, adding a channel unique identifier and a module identifier to the preset data packet to obtain the data packet. The target gateway puts the data packet into a message queue (such as an MQ message queue), and waits until the analysis service consumption is reached, so as to perform format conversion on the data packet to obtain target data. In an actual application process, the analytic service is sent to the target gateway, and then the target gateway sends the analytic service to the communication module, so that a data packet sent to the IoT terminal may be referred to as a downlink data packet (or may also be referred to as an issued data packet).

Specifically, the data packet may also be a data packet obtained after the destination gateway performs packet processing on the data stream or the datagram sent by the communication module. After the target gateway receives the data packet, the target gateway sends the data packet to the resolution service. Under the condition that the target gateway has the identity authentication function, the target gateway can also perform identity authentication on a data packet, so that the data packet subsequently sent to the analysis service can carry a channel unique identifier (namely, a global unique identifier of the Socket). Of course, the unique identifier of the gateway message, the data type of the data packet, the original data encoding format, the communication data (packet/frame), the communication time, and the extension data (e.g., the IP (Internet Protocol Address, IP for short) Address of the source of the data packet, the service level, the will order, etc.) may also be carried.

In a specific embodiment of the present application, the number of target codec processors for performing format conversion on one data packet may be one, or may be multiple. That is, when the format of the packet is converted, the number of target codec processors used may be determined according to the data of the valid data portion in the packet. For example, for a data packet, in the valid data of the data packet, if the first byte carries a temperature value, a target codec processor may be used to perform format conversion on the first byte to obtain a format-converted temperature value; if the second byte to the fifth byte in the valid data carry failure information, another target codec processor can be used to perform format conversion on the second byte to the fifth byte, so as to obtain the failure information after format conversion. Of course, in practical application, the target codec processor may also be adjusted and set according to the data type, coding format, and the like of the valid data in the data packet, and is not limited to the target codec processor mentioned in the above example.

In an actual application process, a communication protocol is added to a received initial data packet of the IoT terminal at the communication module, so as to obtain a preset data packet. After the communication module sends the preset data packet to the target gateway in the form of data stream or datagram, the target gateway needs to perform packet-packet processing on the received data stream or datagram to convert the data stream or datagram into an independent data packet. For a packet, it is essentially a separate packet or frame of data. Which may carry a data packet header, a data packet payload, and a data packet checksum or data packet trailer, among other things. In the processing method, the protocol used by the data packet is divided into a communication protocol and a data protocol, so that the data packet received by the target gateway is the communication protocol of unlimited level and the nesting of the data protocol. Specifically, as shown in fig. 2, for example, a data packet 100 includes a communication protocol header 101 and a communication protocol payload 104, and the communication protocol payload 104 includes an embedded data protocol portion 102 and a check tail 103. As shown in fig. 3, the communication protocol payload 104 may further include a first data protocol 105, a first data payload 111, and a transmission check tail 110 (in an actual application process, the communication protocol payload 104 may also not include the transmission check tail 110), and for the first data payload 111, the first transmission data 106 and the second transmission data 107 may be embedded inside, and the sub-protocol 108 and the sub-protocol data 109 (i.e., the valid data portion of the sub-protocol) may be embedded inside. As shown in fig. 4, the communication protocol payload 104 may further include a second data protocol 112 and a second data payload 113, wherein the second data payload 113 may further embed the plurality of transmission data.

In an embodiment of the application, the data packet carries a channel unique identifier and a module identifier, the channel unique identifier is a global unique identifier of a connection established between the communication module and the target gateway, the module identifier is a unique identifier of the target gateway, and the first determining unit includes a first determining module and a second determining module, where the first determining module is configured to determine the target protocol based on the channel unique identifier of the data packet when the corresponding target protocol can be determined based on the channel unique identifier of the data packet; the second determining module is configured to determine the target protocol of the data packet according to at least the module identifier carried by the data packet under the condition that the corresponding target protocol cannot be determined based on the channel unique identifier of the data packet, which ensures that an analysis service can determine a communication protocol and a data protocol of the data packet relatively easily, and ensures that the calculation amount of the analysis service is small.

In order to determine a communication protocol and a data protocol used by a data packet more simply, in another embodiment of the present application, the second determining module includes a first determining submodule, a searching submodule, and a second determining submodule, where the first determining submodule is configured to determine the communication protocol according to the module identifier of the data packet; the searching submodule is used for searching a corresponding product identifier in a communication module table according to the module identifier of the data packet, wherein the communication module table at least comprises the module identifier and a product identifier, and the product identifier is an identifier of a product formed by the communication protocol and the data protocol; the second determining submodule is configured to determine the data protocol of the corresponding data packet according to the communication protocol and the product identifier. That is to say, according to the module identifier of the target gateway, the outer layer communication protocol of the data packet can be obtained, then the product identifier corresponding to the communication protocol is obtained based on the pre-stored communication module table, the data protocol corresponding to the data packet is obtained, and further the data protocol and the communication protocol corresponding to the data packet are determined relatively simply and accurately.

In order to determine a target codec processor corresponding to a data packet more simply, in another embodiment of the present application, the second determining unit includes a third determining module and a fourth determining module, where the third determining module is configured to determine, when the codec processor corresponding to the data packet is found in a protocol entry table according to a protocol identifier, the found codec processor as the corresponding target codec processor, where the protocol identifier is an identifier of the communication protocol and/or the data protocol of the data packet, and the protocol entry table at least includes the protocol identifier and the codec processor corresponding to the protocol identifier; the fourth determining module is configured to determine a preset codec processor as the corresponding target codec processor if the codec processor corresponding to the data packet is not found in the protocol entry table according to the protocol identifier, so that the processing method of the present application can perform preliminary processing on data by using the preset codec processor even without knowing a communication protocol and a data protocol corresponding to the data packet.

In a specific embodiment of the present application, the protocol entry table may further include a protocol entry identifier, a data index, a data type, and an extension data segment. The data types include integers, floating point numbers, character strings, subprotocol types and function code types. The extension data segment can store corresponding required information in cooperation with the data type, for example, when the data type is a sub-protocol type mark, the protocol identifier of the sub-protocol is stored in the extension data segment.

In yet another embodiment of the application, the parsing service further includes a third determining unit, configured to determine a preset codec processor as the corresponding target codec processor when the target protocol of the data packet is not determined at least according to the module identifier of the target gateway carried by the data packet. In this embodiment, when the communication protocol and the data protocol of the data packet cannot be determined, the preset codec processor is used to determine the target codec processor for the data packet, so that the processing method of the present application can perform preliminary processing on data by using the preset codec processor even without knowing the communication protocol and the data protocol corresponding to the data packet, thereby further ensuring that the processing method of the present application can perform format conversion on the data packet more flexibly.
