Problems solved by technology

Many devices in industrial sites use different communication interfaces. Due to the incompatibility of the protocols of various communication structures, it is difficult to carry out operations and information exchange between heterogeneous networks.
[0003] At present, simple protocol converters are available on the market, which can only complete point-to-point conversion, and mutual conversion between multiple protocols cannot be realized.
There are also some gateway products that can perform protocol conversion, but most of them cannot perform protocol analysis and are directly transparently transmitted. The transparently transmitted data carries various complex protocol headers and format information, which brings a lot of inconvenience to the use of effective data.
[0004] In addition, plaintext data transmission is easily intercepted by hackers and brings unpredictable security risks. The information and data exchange between industrial equipment must be based on the premise of data security and encrypted transmission.

Embodiment 1

[0034] Realize data encrypted exchange between ModbusRTU protocol and ModbusTCP protocol.

[0035] Such as Figure 2-3 As shown, device 1 is the Modbus RTU master protocol, and device 2 is the Modbus TCP slave protocol. Through the intelligent gateway described in this application, device 1 can send a request to device 2, and device 2 responds according to the request.

[0036] The specific steps of the gateway work are:

[0037] 1) Connect the 485 serial port of the intelligent gateway to device 1 with a serial cable, and connect the Ethernet interface of the intelligent gateway to device 2 with a network cable;

[0038] 2) Operate the encryption buttons at the entrance and exit of the gateway to select the data encryption mode; the communication encryption module in the intelligent gateway includes two external encryption modules (encryption module 1 and encryption module 4) , and two built-in encryption modules (encryption module 2 and encryption module 3) in the smart g...

Embodiment 2

[0045] Realize the encrypted data exchange between canopen and mqtt.

[0046] Such as Figure 4-5 As shown, device 1 is the canopen slave station protocol. Through the smart gateway described in this application, device 1 can upload data to the cloud wirelessly, and the cloud can also send data to device 1. In this embodiment, the wireless protocol is introduced using mqtt as an example.

[0047] The specific steps of the gateway work are:

[0048] 1) Connect the CAN interface of the smart gateway to device 1 with the CAN communication line, and start the 4G function of the gateway;

[0049] 2) Operate the encryption buttons at the entrance and exit of the gateway to select the encryption mode; the communication encryption module in the intelligent gateway includes two external encryption modules (encryption module 1 and encryption module 4), And the two built-in encryption modules (encryption module 2 and encryption module 3) in the smart gateway, each encryption module c...

Abstract

The invention discloses a multi-protocol conversion encryption industrial intelligent gateway and an operation method thereof. The intelligent gateway comprises a protocol communication module, a communication encryption module and a core controller, the protocol communication module consists of a plurality of sub-communication modules and is used for connecting various communication interface devices; the communication encryption module is used for data transmission encryption including wired encryption and wireless encryption; and the core controller is based on an ARM+Linux+embedded configuration architecture and is used for communication configuration, protocol analysis, data processing and protocol conversion. According to the invention, different communication protocol devices can be connected, a multi-protocol mutual conversion function is realized, encryption transmission is carried out on data, and information exchange between heterogeneous networks is intelligently completed.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things industrial intelligent gateway, and relates to a multi-protocol conversion encryption industrial intelligent gateway and an operation method thereof. Background technique [0002] With the advancement of information technology, industrial communication often requires information sharing and data exchange between multiple devices. Many devices on the industrial site use different communication interfaces. Due to the incompatibility of the protocols of various communication structures, it is difficult to carry out operations and information exchange between heterogeneous networks. [0003] Currently, simple protocol converters are available on the market, which can only perform point-to-point conversion, and mutual conversion between multiple protocols cannot be realized. There are also some gateway products that can perform protocol conversion, but most of them cannot perform protoc...
