Method and system for bus multiplexing

Abstract

The invention discloses a method and system for multiplexing a bus, relating to the field of intelligent equipment. The method comprises: a JM PIN device host receives a control command sent by a gateway, and detects whether the bus is idle according to the control command, and the JM PIN device host sends a message to the bus The coupling controller sends a disconnection command; the bus coupling controller executes the disconnection command, disconnects the physical connection of the first smart device, and releases the bus occupied by the first smart device; the JM PIN device host sends a bus switching command to the bus coupling controller; The bus coupling controller closes the connection with the second smart device through the second bus coupler, so that the second smart device occupies the bus. The present invention is aimed at smart devices using different bus protocols, and does not need to use a variety of corresponding bus interfaces alone, does not need to lay out multiple buses, and does not need manual operation to switch the connection of different smart devices. The entire operation is completed by the device itself, which is simple. , Convenience, greatly improving the user's sense of use.

Description

technical field [0001] The invention relates to the field of smart devices, in particular to a bus multiplexing method and system. Background technique [0002] At present, with the continuous development of smart homes, home wall-mounted intelligent devices are getting smaller and thinner, which poses new challenges for traditional bus interfaces. At the same time, the increasing demand for multi-system docking in the smart device industry has improved system The complexity of the bus interface puts forward higher requirements for the already stretched bus interface installation space. [0003] In the current traditional way, in order to meet the needs of multi-system and multi-function in the production of smart devices, more smart devices use different buses, and different bus interfaces are produced separately. The overall cost of smart devices is high, there are many types of bus interfaces, and management is difficult. [0004] Only when smart devices using the same ...

[0003] In the current traditional way, in order to meet the needs of multi-system and multi-function in the production of smart devices, more smart devices use different buses, and different bus interfaces are produced separately. The overall cost of smart devices is high, there are many types of bus interfaces, and management is difficult

[0004] Only when smart devices using the same bus protocol are switched can they meet the requirements of multiplexing the same bus, and can use the same bus interface. Naturally, the number of communication lines and reference voltages of the bus interface cannot be changed, resulting in multiple bus protocols. Smart device usage scenarios are limited
