In one embodiment, the data acquisition module 110 includes a plurality of interfaces for accessing the data acquisition unit; the data transmission module 130 includes an output interface, and the standard data are transmitted to the cloud platform through the output interface.
The protocol parsing and converting module 120 is configured to perform protocol parsing on the environment information, and convert the environment information with different communication protocols into standard data in the same format.
Specifically, the protocol parsing and converting module 120 first reads a protocol description configuration corresponding to the communication protocol feature of the environment information; the communication protocol comprises CoAP, MQTT and HTTP communication protocols, and CAN also integrate various different communication protocols such as TCP/IP protocol, CAN protocol (Controller Area Network, control Area Network bus) and Modbus protocol. The CAN protocol is a serial communication protocol bus protocol applied in real time, supports traditional RS-232, RS-422, RS-485 and Ethernet equipment, and realizes conversion among the communication protocols. I.e. the multi-protocol gateway device may receive the above-mentioned data transmitted via a plurality of different communication protocols.
Judging the type and meaning of corresponding environment information according to protocol description configuration, and then reading the data content of the environment information; and packaging the data content to obtain the standard data in the same format. The converted standard data is consistent with a cloud platform network protocol and can be directly transmitted.
In an embodiment, when performing protocol parsing and conversion on the environment information, the protocol parsing and converting module 120 may first convert the environment information with different communication protocols into OPC UA standard data, further convert the obtained OPC UA standard data into MATT protocol data, and then send the MATT protocol data to the cloud platform. The OPC UA standard is a standard that does not depend on any platform, and by which various systems and devices can communicate in different networks, ensuring normal communication of upper and lower networks. After the industrial data with different communication protocols are converted into OPC UA standard data, a protocol analysis and conversion module uniformly packages the OPC UA standard data and converts the OPC UA standard data into a data format with an Internet of things standard, namely MATT protocol data, of a message queue telemetering transmission Internet of things communication protocol, wherein the MATT protocol data supports communication with a cloud platform.
In an embodiment, a hardware access awareness module may be configured in the gateway device to provide a hardware access interface, and a hardware module (sensor) corresponding to a communication protocol is inserted into the access interface, so that the hardware access awareness module reads protocol information of the hardware module and then obtains a protocol description configuration file by configuring the corresponding protocol description configuration file or by updating a remote server.
And a data transmission module 130, configured to transmit the standard data to a cloud platform.
When the gateway device receives a data query instruction sent by a cloud platform, namely a cloud server, the gateway device uploads the encapsulated data packet to the cloud server through a network. Optionally, after the sensor collects the environmental data, the sensor actively packages the collected data and uploads the data to the cloud server through the gateway.
Specifically, there are two kinds of communication modes between sensor and the high in the clouds server: one is that when the cloud server regularly polls all sensors in the whole sensor network, the sensor receiving the polling instruction encapsulates the acquired data through the gateway device and uploads the encapsulated data to the cloud server; and the other is that the data is actively uploaded to a cloud server through gateway equipment after the data is acquired by the sensor.
In an embodiment, the data transmission module 130 is further configured to receive a control instruction sent by the cloud platform, where the control instruction is in a MATT protocol format; the protocol analysis and conversion module is also used for converting the control instruction into standard data and further converting the standard data into instruction data conforming to a protocol format of target network equipment, and the gateway equipment sends the instruction data to the target network equipment.

The user can monitor the field equipment through the cloud platform, can remotely configure and network the field network equipment through the cloud platform, and can issue instructions to the field network equipment from the cloud end according to the uplink data information, so that the cloud end control of the field network equipment is realized.
