The gateway (intelligent gateway) belongs to embedded equipment, and the problem of resource limitation of the equipment needs to be considered in the aspects of memory and bandwidth. The initial purpose of MQTT protocol design is to communicate in limited memory devices and networks with very low bandwidth, and is very suitable for communication between a gateway device and a cloud platform. JSON is a lightweight data exchange format, the simple and clear hierarchical structure characteristics of the JSON enable the JSON to become an ideal data exchange format, and the JSON format is adopted for communication with a lower-end controller and an upper-end cloud platform in gateway equipment. The general application program function of the gateway equipment and the cloud platform comprises three parts: the method comprises the following steps of defining a communication protocol of the controller, realizing the functions of a universal part of cloud platform connection and communication, and realizing the functions of a difference part of different cloud platforms.
The communication data of the intelligent gateway equipment and the controller comprises collected data reporting, control data issuing and response data. The gateway device operates the controller according to the control protocol, and the issued parameters and the description of the acquired data have differences due to different protocol formats. The controller communication protocol definition is to shield the difference of the protocol adopted by the controller, extract the data which is interested by the user and package the data uniformly.
The gateway device and the cloud platform are communicated by adopting an MQTT protocol, the MQTT is based on a client-server communication mode, the gateway device belongs to an MQTT client, and the cloud platform belongs to a Broker server. MQTT client behavior can be summarized as: establishing connection, subscribing a theme, receiving and processing messages, publishing messages to a specified theme, canceling subscription and disconnecting connection, and a special MQTT library is provided to realize corresponding functions. The general function of the gateway equipment and the cloud platform refers to the behavior of an MQTT client realized by an MQTT library; the difference parts among different platforms are in parameters, topoic formats and data communication formats of the connected cloud platforms, can be selected through configuration files, and can also be processed through configuration templates, and specific contents are differentiated according to the cloud platforms.
