Problems solved by technology

However, for the transmission requirements of low-end equipment, it is not necessary to implement the TCP protocol. At the same time, parsing TCP data packets also reduces the transmission rate of the equipment, or the hardware performance of the equipment needs to be greatly improved, thereby greatly increasing the implementation cost.

Embodiment Construction

[0031] 1 to 5 show embodiments of the present invention. As shown in Figure 1, there are TCP devices, RS485 devices, and RF devices in digital homes and smart homes, which are connected to gateway devices with TCP protocol lines, RS485 protocol lines, RF protocol lines and their physical interfaces. The gateway device has a protocol conversion layer for analyzing the data packet and converting the format of the data packet into a format conforming to another protocol interface, and submitting it to the corresponding protocol interface. As shown in Figure 2, the protocol conversion layer is defined in the data protocol layer above, its functions are realized through the following modules (see Figure 3):

[0032] Analyze data routing direction module - used to view the source address and destination address in the data packet, and analyze the routing direction of the data packet;

[0033] Protocol logic conversion module-according to the analysis result of the analysis data rou...

Abstract

The present invention discloses a method for the communication between digital family equipments on the basis of a heterogeneous network protocol. Each equipment is connected with data and transmits data through a gateway equipment, the gateway equipment has a protocol conversion layer which is used to analyze a data packet, convert a data packet format to be a format conforming to another protocol interface and is defined above a data protocol layer. After the gateway equipment receives the data packet, the protocol conversion layer analyzes the routing direction transmitted by the data packet. When the data packet is transmitted to the same physical network, the gateway equipment transmits data to the application layer of network; when the data packet requires to be transmitted to different physical network, a routing selection is performed for the data packet, the data packet is analyzed and the data packet format is converted, and a new data packet is transmitted to a destination network. The present invention simplifies the communication between the heterogeneous networks, improves the communication efficiency, and realizes intercommunication for digital families and intelligent homes and the other equipments which use the heterogeneous networks.

Description

technical field [0001] The invention relates to the technical field of digital home network and computer network communication, in particular to a communication method between devices based on commonly used heterogeneous network protocols in a digital home. Background technique [0002] With the development of digital home and smart home, people have higher and higher requirements for the application of digital home network technology. They hope to use various tools to control home equipment through the Internet, and the home equipment controller can also control the equipment. The status is transmitted to advanced terminals commonly used by people through the Internet, such as mobile phones and PCs. Therefore, the communication between pure physical networks, such as the network communication between TCP on the Internet, the communication between RS485 used in low-end equipment, and the internal communication of RF network can no longer meet people's needs. People hope tha...
