Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] The present invention provides a data protocol conversion method, which is completed by a transparent gateway, and the steps of the method in the uplink direction are as follows: figure 1 shown, including:

[0046] S11. Receive the data packet of protocol A;

[0047] S12. Encapsulate all the data in the above data packet as the payload of the protocol B data packet into a protocol B data packet.

[0048] It should be noted that all the data in the above data packet may include: header and payload of the data packet.

[0049] Optionally, after S12, the above method may further include: sen...

Abstract

The invention is applied to the communication field. The invention provides a protocol conversion method of data, a gateway and a system. The method comprises the following steps: in an uplink direction: receiving a data packet of a protocol A; taking all data in the data packet as a payload of a protocol B data packet, wherein, the payload is packaged as a data packet of a protocol B; in a downlink direction: receiving the protocol B data packet, and taking the payload in the protocol B data packet as a protocol A data packet. A technical scheme provided in the invention has the advantages of low cost and convenient maintenance.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a data protocol conversion method, gateway and system. Background technique [0002] At present, in industrial control and automation, there are various products based on different communication technologies and communication protocols in the field of building automation and communication. At present, the protocols transmitted between various products are different, so a complete, effective and powerful automation or communication system is often the integration of various products and subsystems. Due to the characteristics of each product and subsystem, the application of each product and subsystem The protocols are different. At this time, the gateway (Gateway) is required to convert the data between different networks and protocols to achieve data protocol conversion. Assume that the protocol before conversion is protocol A, and the protocol after conversion is protocol B...
