Abstract
RS232/RS485 that can free expansion port quantity changes ethernet gateway equipment, comprise host platform, led display unit, power supply processing unit and port arrangement unit, host platform is based on ARMCPU processing platform or embedded Linux platform, host platform is connected with the USB input/output interface, realize expanding by the USB input/output interface, host platform is connected with Ethernet interface simultaneously, docks with Ethernet.The advantage of this equipment is that RS485, RS232 port can expand arbitrarily, can reduce the engineering input cost greatly.The parameter of port can be set the parameter of each mouthful by computer by setting port.Ethernet side can be as local fetch equipment data by obtaining this equipment corresponding virtual serial ports in windows installation driving.
Description
Technical field
The present invention relates to a kind of gateway device, specifically a kind of gateway device that changes Ethernet by free agreement RS232, RS485.
Background technology
The industry control industry uses a lot of instrument to need communication modes to collect central control room by Ethernet at present, and the settling mode of present this demand can only be realized communication by PLC or miscellaneous equipment programming.This way can cause debugging cycle and project quality to be difficult to guarantee, all be man-to-man transmission to the equipment of Ethernet at present at the device translates of this RS232/RS485, when equipment is many, can cause the equipment purchase amount to increase, we at this present situation developed a cover can transparent transmission RS232/RS485 to the equipment of Ethernet, and unify the place port number and can add the quantity port arbitrarily.The user only need can be implemented to data transmission of Ethernet by setting some parameters.
The advantage of this equipment is that RS485, RS232 port can expand arbitrarily, can reduce the engineering input cost greatly.
The parameter of port can be set the parameter of each mouthful by computer by setting port.
Ethernet side can be as local fetch equipment data by obtaining this equipment corresponding virtual serial ports in windows installation driving.
Summary of the invention
The purpose of this invention is to provide a kind of RS232/RS485 that can free expansion port quantity changes ethernet gateway equipment, realizes the switching from free agreement RS232, RS485 to Ethernet.
Technical scheme of the present invention:
RS232/RS485 that can free expansion port quantity changes ethernet gateway equipment, comprise host platform, led display unit, power supply processing unit and port arrangement unit, host platform is based on ARM CPU processing platform or embedded Linux platform, host platform is connected with the USB input/output interface, realizes expanding by the USB input/output interface; Host platform is connected with Ethernet interface simultaneously, docks with Ethernet; Led display unit is connected with host platform, video data conversion and transmission parameters.
The advantage of this equipment is that RS485, RS232 port can expand arbitrarily, can reduce the engineering input cost greatly.
The parameter of port can be set the parameter of each mouthful by computer by setting port.
Ethernet side can be as local fetch equipment data by obtaining this equipment corresponding virtual serial ports in windows installation driving.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is that RS232/RS485 that can free expansion port quantity of the present invention changes the structured flowchart of ethernet gateway equipment.
Among the figure: 1, host platform; 2, USB input/output interface; 3, Ethernet interface; 4, led display unit.
Embodiment
With reference to figure 1, RS232/RS485 that can free expansion port quantity changes ethernet gateway equipment, comprise host platform 1, led display unit, power supply processing unit and port arrangement unit, host platform 1 is based on ARM CPU processing platform or embedded Linux platform, host platform 1 is connected with USB input/output interface 2, realizes expanding by USB input/output interface 2; Host platform 1 is connected with Ethernet interface 3 simultaneously, docks with Ethernet; Led display unit 4 is connected with host platform 1, video data conversion and transmission parameters.
The advantage of this equipment is that RS485, RS232 port can expand arbitrarily, can reduce the engineering input cost greatly.
The parameter of port can be set the parameter of each mouthful by computer by setting port.
Ethernet interface 3 can be as local fetch equipment data by obtaining this equipment corresponding virtual serial ports in windows installation driving.
The function that the present invention realizes be embodied in following some:
1, serial port gateway equipment is realized the function that port expands arbitrarily.
Equipment in the market all is 1 pair 1 mode, and our design is the mode of expansion port arbitrarily, can only need to buy a corresponding docking station annex and get final product for after the user buys a main frame like this, does not need to repeat purchase, has reduced engineering cost.
2, adopt USB interface to expand.
Extended mode adopts the USB mode, makes things convenient for user's expansion port, and interface adopts popular USB mode.
3, customer end adopted virtual serial port technology is convenient to the user software direct communication.
The client user only need install the corresponding driving program can generate corresponding virtual serial port, and the user does not need to change original local application and can realize.
Claims (3)
1, RS232/RS485 that can free expansion port quantity changes ethernet gateway equipment, it is characterized in that, comprises host platform, and the USB input/output interface and the Ethernet interface that are connected with host platform.
2, RS232/RS485 that can free expansion port quantity according to claim 1 changes ethernet gateway equipment, it is characterized in that host platform is based on ARM CPU processing platform or embedded Linux platform.
3, change ethernet gateway equipment according to claim 1 or described RS232/RS485 that can free expansion port quantity, it is characterized in that, also comprise led display unit, be connected with host platform.
