The device comprises a terminal for remote protocol configuration, an industrial wireless network, and a data access card supporting the multi-protocol; the device function comprises a manufacturing equipment communication protocol base, a configurable communication protocol format parameter, and a newly added manufacturing equipment convenient access intelligent manufacturing system; the method comprises the following steps: establishing an editable application layer protocol base on a computer or a mobile phone according to different manufacturing equipment communication protocol format requirements; configuring an application layer communication protocol on the computer or an intelligent mobile phone according to a new equipment communication requirement when the new manufacturing equipment is accessed into the manufacturing system; downloading the configured application layer communication protocol data to the data access card, storing and updating the communication protocol, and accessing the newly added equipment into the manufacturing system. The device adopts the configurable multi-protocol data access device aiming at the manufacturing equipment access problem under the industrial 4.0 background, so that the manufacturing equipment can be conveniently accessed into the manufacturing system.

Description

technical field [0001] The invention relates to a multi-protocol data access method and device, in particular to a configurable multi-protocol data access method and device in an industry 4.0 environment. Background technique [0002] The communication agreement refers to the rules and agreements that must be followed by the two entities to complete the communication or service. Multiple data communication systems in different geographical locations interconnected through communication channels and devices must have a communication protocol in order to enable them to work together to achieve information exchange and data transmission. In the traditional manufacturing environment, the data transmission method is basically fixed. A manufacturing device corresponds to a communication protocol, that is, after a device is connected, data transmission can only be performed according to the protocol and fixed protocol parameters of the device, and cannot be changed dynamically. ...

Problems solved by technology

However, in the manufacturing environment, the equipment uses multiple data access cards with a single communication protocol, which increases the complexity of the hardware architecture, makes installation and modification more difficult, and many hardware devices also increase energy consumption.

In addition, when a new protocol is connected, this interface can only transmit data at the set parameters, and cannot be configured according to the actual situation of the manufacturing site. The real-time performance and reconfigurability are poor, and remote configuration and optimization of equipment resources cannot be realized.
