Problems solved by technology

At present, most communication protocols based on RS485 are only suitable for one-way data acquisition and other applications, and cannot meet the requirements of two-way control and node independence for switches in the home field.

Embodiment Construction

[0024] see Figure 1 to Figure 4 , a communication method based on an intelligent switch, the communication method is realized based on a network with a plurality of switch panels, the switch panels include a lighting panel, a curtain panel and a dimming panel, each switch panel is provided with At least one group of buttons, each group of buttons independently controls different states of the same object, any number of scene buttons can be set on each switch panel, each scene button defines a scene mode, and the communication between each switch panel is carried out through the communication method Communication; the communication method needs to provide a physical network topology module, a bus conflict processing module and a node data processing module;

[0025] Such as figure 1 As shown, the physical network topology module includes all switch panels and buses in an area, each switch panel is connected through the bus, one switch panel is a node, and each node can commun...

Abstract

The invention provides a communication method based on an intelligent switch. The communication method is realized based on a network provided with a plurality of switch panels. The communication method is characterized in that the switch panels are provided with at least one group of buttons, each group of buttons is used to independently control different states of a same material object, each switch panel can be provided with any number of scene buttons, each scene button is used to customize a scene mode, the switch panels are controlled mutually through the communication method; and the communication method comprises a physical network topological structure module, a bus contention processing module and a node data processing module. According to the invention, the mutual communication between intelligent switch nodes can be realized, and at the same time, reverse recording is adopted by the method of the invention, the nodes are processed in a distributed manner and received, stored and controlled independently, so the communication efficiency, performance and flexibility of the intelligent switch can be greatly improved.

Description

technical field [0001] The invention relates to a communication protocol, in particular to a communication method based on an intelligent switch. Background technique [0002] The RS485 communication bus only defines the electrical specifications of the physical layer, and there is no conflict detection or arbitration mechanism. Therefore, when traditionally using RS485 for communication, it is necessary to define an upper-layer communication protocol, such as the MODBUS protocol, which can only use a master-multiple-slave structure, and the slaves cannot communicate with each other, and can only exchange information through the master polling to reach indirect control. In this one-master-multiple-slave structure, once the host fails, the network cannot work normally, and the control records of multiple targets are all stored on the host, which makes the control and call time long and not flexible enough. Each switch control node in the home furnishing field should be relat...
