Problems solved by technology

[0011] Although this type of switching technology can enable one type of interface to connect devices with multiple interface types, the switching module usually includes a dedicated chip inside to perform complex protocol conversion algorithms, so this will also lead to an increase in cost
[0012] On the other hand, the conversion between interface protocols may also lead to poor implementation of communication between the gateway and the device. For example, in the process of the gateway assigning addresses to smart devices, the delay caused by protocol conversion may make the address assignment The efficiency of the machine is reduced, which in turn affects the function of smart devices

Embodiment Construction

[0042] Figure 6 It shows the specific structure of the smart home network disclosed by the present invention, mainly including the digital home smart gateway inside the home. The gateway connects various intelligent devices through the bus switch, Ethernet bus, and 485 bus.

[0043] In data communication, computer network and distributed industrial control system, it is often necessary to use serial communication to realize data exchange. At present, there are several interface standards such as RS-232, RS-485, and RS-422 for serial communication. RS-232 is the earliest serial interface standard, which has been widely used in short distance (<15M) and lower baud rate serial communication. Later, aiming at the short communication distance and relatively low baud rate of the RS-232 interface standard, the RS-422 interface standard and the RS-485 interface standard were proposed on the basis of the RS-232 interface standard to overcome these defects.

Abstract

The invention relates to gateway equipment, which comprises at least one RJ45 interface, an Ethernet controller and a 485 bus controller, wherein the RJ45 interface is used for connecting other equipment through twisted pairs; the Ethernet controller is connected with a first pin, a second pin, a third pin and a sixth pin of at least one RJ45 interface and is used for exchanging Ethernet data with other equipment through at least one RJ45 interface; and the 485 bus controller is connected with a fourth pin, a fifth pin, a seventh pin and an eighth pin of at least one RJ45 interface and is used for exchanging 485 bus data with other equipment through at least one RJ45 interface. The gateway equipment with a port multiplexing function integrates an Ethernet interface and a 485 bus interface into a single RJ45 interface, so that an intelligent gateway can process the Ethernet data and the 485 bus data in parallel not to generate mutual interference, the function of the single RJ45 interface is expanded, and meanwhile, the problem of cost increasing caused by increasing different types of interfaces or carrying out protocol conversion is also solved.

Description

technical field [0001] The invention relates to a gateway device in a smart home network, and in particular to a gateway device with a port multiplexing function in a smart home network environment.
