The invention discloses gateway equipment, a data transmission method and a storage medium. The data transmission method comprises the following steps: acquiring a source signal sent by source equipment; analyzing the acquired source signal, so as to obtain data segment information of the source signal, wherein the data segment information comprises a source address, a valid data segment and a target address; according to prestored mapping relation between function codes and the target address, determining the function codes of the target equipment corresponding to the target address, whereinthe function codes are bytes of a preset type and with preset length and are used for identifying a data frame type supported by the target equipment; analyzing the valid data segment to obtain accessparameters corresponding to the target equipment, converting the access parameters obtained through analyzing into a data frame format supported by the target equipment according to the function codes of the target equipment, and sending to the target equipment, wherein the valid data segment comprises the access parameters of the target equipment. The data transmission method disclosed by the invention solves the problem that universality of the gateway equipment is poor.
Description
technical field [0001] The invention relates to the field of intercommunication, in particular to a gateway device, a data transmission method and a storage medium. Background technique [0002] Gateway (Gateway) is also called Internet connector and protocol converter. In the process of data communication between devices, it usually passes through a gateway device. [0003] Generally, the commonly used gateway devices only support the conversion of a single communication protocol, such as conversion based on the http protocol, or only support the conversion of communication protocols such as Modbus and CAN, and cannot realize seamless switching between multiple protocols, resulting in gateway devices poor versatility. Contents of the invention [0004] In view of this, the present invention proposes a gateway device, a data transmission method and a storage medium, which can accurately and effectively improve the versatility of the gateway. [0005] First, in order to ...
