It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 shows an exemplary system architecture 100 of an embodiment of a synchronization method of timing messages or a synchronization apparatus of timing messages to which the present application may be applied.
As shown in fig. 1, system architecture 100 may include device 101, network 102, server 103. Network 102 is the medium used to provide communication links between devices 101 and server 103. Network 102 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.
Device 101 may interact with server 103 through network 102. Various timing messages may be provided in the device 101, including but not limited to sensors, smart devices, and the like.
The server 103 may provide various services, for example, the server 103 may analyze and process data such as a timing message acquired from the device 101, and generate a processing result (e.g., synchronize to a timing database).
The server 103 may be hardware or software. When the server 103 is hardware, it may be implemented as a distributed server cluster composed of a plurality of servers, or may be implemented as a single server. When the server 103 is software, it may be implemented as multiple pieces of software or software modules (e.g., to provide distributed services), or as a single piece of software or software module. And is not particularly limited herein.
It should be noted that the server 103 may be any edge computing platform with converged network, computing, storage, and application core capabilities from a data source (i.e., the device 101) to a cloud computing center, and the cloud computing center may access history data of the edge computing platform.
It should be noted that the synchronization method for the timing message provided in the embodiment of the present application is generally executed by the server 103, and accordingly, the synchronization device for the timing message is generally disposed in the server 103.
It should be understood that the number of devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of devices, networks, and servers, as desired for an implementation.
With continued reference to fig. 2, a flow 200 of one embodiment of a method for synchronization of timing messages in accordance with the present application is shown. The method comprises the following steps:
step 201, converting the original time sequence message collected from the device into a first format time sequence message corresponding to a preset internet of things message protocol.
In this embodiment, an executing body (e.g., the server 103 shown in fig. 1) of the synchronization method of the timing message may convert an original timing message collected from the device into a first format timing message corresponding to a preset internet of things message protocol.
The local protocol for short-distance device connection can be used to collect the original timing message of the device, such as MODBUS protocol, OPC protocol, etc. The MODBUS protocol is a protocol set supporting various physical links, the core of the MODBUS protocol is a serial communication protocol, a master-slave mode is adopted, a master sends a request to a slave, and the slave replies. Wherein the slave may be the device 101 shown in fig. 1. The OPC protocol is a data protocol of an application layer and is used for transmitting automatically acquired equipment data to a host in a certain format.
After the original time sequence message of the equipment is collected by adopting the local protocol, the original time sequence message can be converted into the time sequence message in the first format based on a preset Internet of things message protocol. The Message Protocol of the internet of things may be an internet Protocol supporting the internet of things for global communication, such as a Message queue Telemetry Transport Protocol (MQTT), a restricted Application Protocol (COAP), an Advanced Message Queue Protocol (AMQP), and the like. The message is acquired by adopting different internet of things message protocols, and the formats of the acquired messages are different. By adopting the example of MQTT protocol, the MQTT message format is as follows: [ Fixed Header | Variable Header | Payload ]; the Fixed Header comprises a first byte, wherein the high 4 bits are used for representing the message type, and the low 4 bits are used for type control; variable Header is a Variable Header, which differs according to the type of message; payload is the content of a message, and the content and format of the Payload also differ according to the type of the message.
Step 202, the first format timing message is converted into a second format timing message adapted to be stored in a timing database.
In this embodiment, the execution body may convert the first format timing message into a second format timing message adapted to be stored in the timing database.
The Time Series Database (TSDB) is used to store Time Series (chronological) massive data, and the data in the Time Series Database may be stored in the form of data points (datapoints). Where "1 measure +1 field (optional) +1 timestamp +1 value + n tags (n > -1)" may define a data point, e.g. "temperature, 20201010121200 (timestamp), 25 ℃, { device ID ═ 3410938109; floor 13; room number 2301} ".
Wherein the first format time series messages can be converted into data points suitable for storage in a time series database, including numerical padding, time padding, and the like, based on the message content of the first format time series messages.
Step 203, establishing a connection with the time sequence database according to the configuration information of the time sequence database provided by the user.
In this embodiment, the execution subject may establish a connection with the time sequence database according to configuration information of the time sequence database provided by a user.
The configuration information may be related parameter information of the connection timing database instance, including but not limited to a domain name, a connection address, a port, an account password, and the like. The user can configure the connection address and the related parameters of the time sequence database, and the execution main body establishes the connection with the time sequence database through the client code of the integrated time sequence database. The client code has the function of submitting data, and the data is submitted to the server after being acquired by the user.
Step 204, synchronizing the second format timing message to a timing database.
In this embodiment, the execution body may synchronize the second format timing message to the timing database.
After establishing connection with the time sequence database, the time sequence message in the second format may be sent to the time sequence database by using a hypertext Transfer Protocol (HTTP). The time sequence database can be a time sequence database deployed in a cloud computing center and a time sequence database cluster.
The synchronization method of the time sequence messages provided by the embodiment of the application supports the direct synchronization of the edge time sequence messages to the time sequence database, is simple and convenient in process and simple in configuration, saves cloud resources, and reduces the difficulty of program debugging.
With further reference to fig. 3, there is shown a flow chart of another embodiment of synchronization of timing messages, the method comprising the steps of:
step 301, converting the original time sequence message collected from the device into a first format time sequence message corresponding to a preset internet of things message protocol.
Step 301 is substantially the same as step 201, and therefore will not be described again.
Step 302, converting the first format timing message into a second format timing message adapted to be stored in a timing database.
Step 302 is substantially the same as step 202, and therefore is not described in detail.
Step 303, establishing a connection with the time sequence database according to the configuration information of the time sequence database provided by the user.
Step 303 is substantially the same as step 203, and therefore is not described in detail.
Step 304, the second format timing message is encrypted using a signature algorithm.
The signature algorithm refers to an algorithm of digital signature. The Digital Signature is a message digest Algorithm with a key, the key includes a public key and a private key, and is used for verifying data integrity, authenticating data source and resisting denial, and follows an Open System Interconnection (OSI) reference model, private key Signature and public key verification, and the Digital Signature Algorithm includes an RSA Algorithm, a DSA Algorithm, an Elliptic Curve Digital Signature Algorithm (ECDSA), and the like. And the signature algorithm is adopted to encrypt the second format time sequence message, so that the safety of the synchronous time sequence message is ensured.
Step 305, sending the second format time sequence message to a time sequence database by adopting a hypertext transfer protocol.
The hypertext transfer protocol is a request-response protocol, which generally runs on top of TCP, and belongs to the prior art, and is not described in detail herein.
In some optional implementations of this embodiment, the configuration information of the time-series database in step 203 includes a client certificate of the time-series database, and before performing step 203, the method further includes: and verifying the legality of the client certificate.
The client certificate is a digital certificate complying with a network communication security protocol, and the client certificate can be used for realizing double functions of real identity authentication and data encryption transmission. Before data interaction, the execution subject may store a client certificate provided by a user. The client certificate includes an SSL certificate, an SSH certificate, a PGP certificate, and the like.
Wherein the validity of the client certificate may be verified before establishing a connection with the timing database. In which plaintext message data encrypted using a client certificate may be decrypted to verify authenticity of the identity.
In some optional implementations of this embodiment, before performing step 201, the method further includes: the original time sequence message is encrypted using a digital certificate to obtain a root certificate and the certificate used in step 201 is issued based on the root certificate.
The method for encrypting the original timing message is basically the same as that in step 304, and thus is not described in detail. The root Certificate is a Certificate issued by a Certificate Authority (CA) center to itself, and is a starting point of a communication trust chain. The CA center may issue a digital certificate for each user using the public key, the digital certificate serving to prove that the user listed in the certificate has legitimate possession of the public key listed in the certificate. Wherein, the CA center may issue a certificate used when performing step 201 to ensure security when performing step 201.
In some optional implementations of this embodiment, before performing step 202, the method further includes: based on the root certificate, a certificate is issued for use in converting the first format timing message into a second format timing message.
The root Certificate is a Certificate issued by a Certificate Authority (CA) center to itself, and is a starting point of a communication trust chain. The CA center may issue a digital certificate for each user using the public key, the digital certificate serving to prove that the user listed in the certificate has legitimate possession of the public key listed in the certificate. Wherein, the CA center may issue a certificate used when performing step 201 to ensure security when performing step 202.
For ease of understanding, fig. 4 shows an application scenario diagram of an embodiment of a synchronization method of a timing message according to the present application.
As shown in fig. 4, in order to implement the synchronization method of the time sequence message according to the present application, a local message flow module, a global certificate module, a TSDB message conversion module, and a TSDB message synchronization module may be configured. The message circulation module is an end-side message system, supports end-side message forwarding, and is connected with the data acquisition module at the edge side, and the adopted protocols include but are not limited to MODBUS and OPC protocols. The format of the message to be forwarded is not limited to MQTT and COAP protocols.
The global certificate module is used for guaranteeing the safety of message communication between the end side modules, and supporting the end side modules to issue module certificates, and the modules can be encrypted and decrypted by using the module certificates, so that the end side messages can not be stolen. And meanwhile, the client certificate of the TSDB cluster is stored and provided for the TSDB message synchronization module to use.
Wherein, the TSDB message conversion module converts the element message of the device into a TSDB time sequence message and then sends the TSDB message synchronization module. Wherein the elements include metrics, domains, timestamps, values, tags, and the like.
The TSDB message synchronization module establishes a secure connection with the TSDB cluster by using a client certificate of the TSDB cluster, and performs message synchronization in real time.
