Embodiment Construction

[0019] Fig. 1 is a network topology diagram of Internet-based distributed weighing equipment according to an embodiment of the present invention.

[0020] As shown in FIG. 1 , the weighing devices 112 , 114 , 116 , and the weighing devices 122 , 124 communicate with the web server 10 through the Internet. In a preferred solution, the HUB11 gathers the weighing devices 112, 114, and 116 and then accesses the Internet through the ADSL Modem 11. Equally, HUB12 ' connects Internet through ADSLModem12 after weighing equipment 122,124 gathers. In another example, each weighing device directly accesses the Internet through ADSL.

[0021] Each weighing device 112, 114, 116, 122, 124 is assigned a unique device identification number. In a preferred solution, the device identification number of the device itself, the identification number of the requested networking device and the IP address of the network server are written into each device in advance. Then, a device communication p...

Abstract

The present invention provides a method and a system for the communication between the embedded devices based on Internet. The method comprises the following steps: a. a first equipment sends the networking request data for communication with a second equipment to a network server; wherein, the networking request data consists of the identification number of the first equipment and the identification number of the second equipment; the first equipment, the network server and the second equipment are connected through Internet; b. the network server judges the accuracy of the identification number of the first equipment and the identification number of the second equipment, and sends the response data to the first equipment in the condition of accuracy, and the response data consists of the IP address of the second equipment; c. the first equipment starts the communication with the second equipment according to the IP address of the second equipment.

Description

technical field [0001] The invention belongs to the field of networking communication, and in particular relates to a communication method and system between embedded devices based on the Internet. Background technique [0002] With the development of society, there is often a need for communication between multiple embedded devices located in different locations. For example, weighing equipment, in addition to trade settlement, has also been applied to many new fields, such as: ingredients, packaging, check weighing, road toll weighing, commercial retail management and so on. Therefore, real-time and effective data transmission is required between multiple devices as well as between devices and the management center, and it is hoped that remote network communication can be established. However, the distance between multiple devices and the management center is often far away, even not in the same city, so the method of networking with the usual data line is a huge project,...
