Problems solved by technology

[0002] At present, the internal programs of the existing intelligent management terminals use socket communication, and each program manages multiple socket communication channels. This prior art needs to pre-define the communication channels between mutual communication programs, and needs to provide The channel allocates a unique communication port, and each program needs to manage the communication between the client and the server, which makes the communication of each program occupy a large amount of resources and is not easy to maintain, and a single communication port enables scalability between programs poor

Abstract

The invention discloses an embedded multi-program communication method and system. The method comprises the following steps: establishing an MQTT server and a plurality of MQTT clients; wherein each MQTT client is configured with an application program; the application program issues an application message to the MQTT server; and the MQTT server forwards the application message to the corresponding MQTT client according to the theme label in the application message. The application message adopts JSON format data, and the JSON format data comprises a message header, a source program theme name, a target program theme name, a frame number, a transmission direction and message content. According to the invention, mutual communication among a plurality of programs can be realized through theMQTT server, and the client does not need to manage a server communication channel, so that the resource occupation can be reduced, and the cooperative operation of the plurality of programs can be realized.

Description

technical field [0001] The invention relates to the communication field, in particular to an embedded multi-program communication method and system. Background technique [0002] At present, the internal programs of the existing intelligent management terminals use socket communication, and each program manages multiple socket communication channels. This prior art needs to pre-define the communication channels between mutual communication programs, and needs to provide The channel allocates a unique communication port, and each program needs to manage the communication between the client and the server, which makes the communication of each program occupy a large amount of resources and is not easy to maintain, and a single communication port enables scalability between programs poor. Contents of the invention [0003] One of the invention objectives of the present invention is to provide an embedded multi-program communication method and system. The method and system ad...
