Problems solved by technology

This approach will make it difficult to guarantee the debugging cycle and project quality. At present, the conversion of such RS232 / RS485 equipment to Ethernet equipment is one-to-one transmission. When there are many equipment, it will lead to an increase in equipment purchase. We aim at this This situation has developed a set of equipment that can transparently transmit RS232 / RS485 to Ethernet, and the number of ports in a unified location can be added to any number of ports

Embodiment Construction

[0015] refer to figure 1 , the RS232 / RS485 to Ethernet gateway device that can freely expand the number of ports, including host platform 1, LED display unit, power processing unit and port configuration unit, host platform 1 is based on ARM CPU processing platform or embedded Linux platform, host platform 1 is connected with the USB input and output interface 2, and the expansion is realized through the USB input and output interface 2; at the same time, the host platform 1 is connected with the Ethernet interface 3, and is docked with the Ethernet; the LED display unit 4 is connected with the host platform 1, and displays data conversion and transmission parameter.

[0016] The advantage of this device is that the RS485 and RS232 ports can be expanded arbitrarily, which can greatly reduce the project investment cost.

[0017] The parameters of the port can set the parameters of each port by setting the port through the computer.

[0018] The Ethernet interface 3 can read t...

Abstract

The invention relates to RS232/RS485 Ethernet gateway equipment capable of extending port number freely, which comprises a host platform, an LED display unit, a power processing unit and a port configuration unit, wherein the host platform is based on an ARMCPU processing platform or an embedded Linux platform and is connected with a USB input/output interface; the extension is achieved through the USB input/output interface; and meanwhile, the host platform is connected with an Ethernet interface and is in butt joint with the Ethernet. The RS232/RS485 Ethernet gateway equipment capable of extending port number freely has the advantages that an RS485 port and an RS232 port can be extended freely, thus the engineering investment cost can be greatly reduced; the parameter of each port can be set through a computer by setting each port; and the Ethernet terminal acquires a virtual serial port corresponding to the equipment by installing drivers in windows, thus the equipment data can be read like the data is stored in the local computer.

Description

technical field [0001] The invention relates to a gateway device, in particular to a gateway device for converting from free protocol RS232 and RS485 to Ethernet. Background technique [0002] At present, many instruments used in the industrial control industry need to communicate with the central control room through Ethernet, but the current solution to this demand can only be realized through PLC or other equipment programming. This approach will make it difficult to guarantee the debugging cycle and project quality. At present, the conversion of such RS232 / RS485 equipment to Ethernet equipment is one-to-one transmission. When there are many equipment, it will lead to an increase in equipment purchase. We aim at this Based on this situation, a set of equipment that can transparently transmit RS232 / RS485 to Ethernet has been developed, and the number of ports in a unified location can be added to any number of ports. Users only need to set some parameters to realize data ...
