Problems solved by technology

[0003] The ZNE-100TL intelligent embedded Ethernet serial port conversion module and the ZNE-300TI full-featured industrial-grade embedded Ethernet serial port conversion module in the current market can only realize the network communication between the server and up to 4 client stations; the above two modules Without buffer memory, when data bursts (multiple customer site network data arrive at the same time), the data communicated between the client site and the server network will be lost

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. The multi-site network communication controller of the present invention is preferably a network communication controller embodiment that controls 80 client sites, but the present invention is not limited to the following embodiments.

[0027] An 80-site network communication controller is composed of a network switch, 20 sub-station network controllers, and network communication controllers. Through the master control server, Internet-based remote monitoring of 80 customer sites can be realized.

[0028] The customer site is composed of equipment control device, RS232 serial interface and Ethernet serial conversion module-I. The equipment control device realizes the effective control of the production equipment, and the RS232 serial interface realizes the communication between the equipment control device and the Ethernet serial conversion modul...

Abstract

The invention discloses a multi-station network communication controller which is formed by connecting a network communication controller (10), a plurality of substation network controllers (20) and a network switchboard (30) in sequence and realizes Internet network-based remote control in such a way that the network communication controller (10) is connected with a master control server. The network communication controller (10) is formed by connecting two RS232 serial interfaces (11), a single chip microcomputer C8051F120(12) and a bus driver (15) in sequence; the network communication controller (10) is connected with at least two substation network controllers (20); each substation network controller (20) is formed by connecting a double-port RAM (21), a single chip microcomputer C8051F340 (20) and an Ethernet serial converting module-II (26) in sequence; the substation network controller (20) corresponds to one to four client stations; and the Ethernet serial converting module-II (26) is connected with the Internet network through the network switchboard (30). The invention can realize remote online monitoring on a plurality of client stations.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a network communication controller capable of remotely controlling multiple stations. Background technique [0002] With the development of network technology, many terminal devices now have the function of surfing the Internet, and these terminal devices need to realize remote control and information management of the terminal devices through the network. For example, retail stores such as network control centers, comprehensive office areas, and supermarkets have many terminal devices, as well as production process control equipment and instruments in the industrial field. These terminal devices are customer sites. [0003] The ZNE-100TL intelligent embedded Ethernet serial port conversion module and the ZNE-300TI full-featured industrial-grade embedded Ethernet serial port conversion module in the current market can only realize the network communication between t...
