Abstract
The invention provides a system for redirecting serial data and a method thereof; wherein, the redirection system includes a client; the client is provided with a browser and is connected with a management server through HTTP; the management server is connected with a plurality of managed servers through LAN; the redirection method is achieved by the redirection system and comprises the following steps: the browser judges whether input information is acquired or not; when the browser acquires the input information, the browser can judge whether the input information is disconnection; if when the browser determines the input information is not disconnection, the input information is sent to the managed server through the management server; when the managed server receives the input information, corresponding information is returned to the management server; then monochrome text and color text on the managed server are output and displayed by the browser on the client. Therefore, a vacant serial port and serial cable used for connecting the serial port are not needed, and the invention can be applied conveniently.
Description
[technical field]
The invention provides a kind of Redirectional system of serial data and the reorientation method of serial data, particularly a kind of application is the Redirectional system of serial data and the reorientation method of serial data easily.
[background technology]
The control desk redirection function allows to export the maintenance of far end server by being redirected keyboard input and text.The control desk redirection function can be used for the BIOS setting, RAID is provided with, and shows the POST process and executive program under the MS-DOS system.In order to use redirection function, the user can use the serial ports of direct Connection Service device of serial interface cable and client computer usually, but the condition of this kind solution is that idle serial ports and the serial interface cable in order to connect are arranged on the client-server; Also need the such terminal emulator of similar hyper terminal on the client computer simultaneously, and this type of software needs higher version with support direction key and function key.Existing solution implements comparatively limited.
[summary of the invention]
Main purpose of the present invention is to provide a kind of application Redirectional system of serial data and the reorientation method of serial data easily.
For reaching above purpose, the invention provides a kind of Redirectional system of serial data; It comprises some by the pipe server, it is respectively in order to receive the UDP message bag and to convert the UDP message bag that receives to the reception serial data, and, will return UDP message bag and output that serial data converts passback to again according to receiving the corresponding passback of serial data acquisition serial data; All are managed server and are connected a management server by local area network (LAN), and are realized transmitted in both directions between management server and the quilt pipe server, and this management server is in order to change UDP message bag and tcp data bag mutually; This management server connects a client computer by HTTP, realize transmitted in both directions between this client computer and the management server, and this client computer is provided with a browser, the tcp data bag that this browser transmits in order to the receiving management server, and the tcp data bag shown by browser window, and, input information can be exported with the tcp data bag in order to receive input information.
The present invention also provides a kind of reorientation method of serial data, its Redirectional system by serial ports data is to reach, this Redirectional system comprises a client computer, a management server and some by the pipe server, wherein, be provided with a browser in this client computer, and be connected by HTTP between this client computer and the management server, and management server and being connected by local area network (LAN) between the pipe server, and this reorientation method may further comprise the steps: browser judges whether to obtain input information; When browser obtains input information, can judge whether this input information is to disconnect connecting; If it is not when disconnect connecting that browser is judged this input information, then obtains the tcp data bag of transmission according to input information, and the tcp data bag that transmits is sent to by the pipe server by management server; When being received the tcp data bag of transmission by the pipe server, obtain the reception serial data according to the tcp data bag that transmits, and obtain corresponding passback serial data according to receiving serial data, will return the UDP message bag that serial data converts passback to again and send to management server; Management server receives the UDP message bag of passback, and obtains the tcp data bag of passback according to the UDP message bag of passback, and the tcp data bag of passback is sent to browser; Browser receives the tcp data bag of passback, and the output videotex.
Compared to prior art, the present invention comes the connection management server and by the server managed, does not need serial interface cable to connect by local area network (LAN), and the present invention only uses browser to come remotely administered server, need not the client install software, and it is comparatively convenient to use.
[description of drawings]
Fig. 1 is the functional-block diagram of the Redirectional system of serial data of the present invention.
Fig. 2 is the flow chart of the reorientation method of serial data of the present invention.
[embodiment]
See also shown in Figure 1, the Redirectional system of serial data of the present invention comprises some by pipe server 10, these are managed server 10 respectively in order to receive UDP (User Data Protocol, User Datagram Protoco (UDP)) packet, the UDP message bag that receives can be in being become to receive serial data by 10 internal conversions of pipe server, obtain corresponding passback serial data according to receiving serial data again, the passback serial data can be in the UDP message bag and the output that are become passback by 10 internal conversions of pipe server.These are managed server 10 respectively by LAN (Local AreaNetwork, local area network (LAN)) connects a management server 20, and realized transmitted in both directions between management server 20 and the quilt pipe server 10, this management server 20 is in order to change UDP message bag and TCP (TransmissionControl Protocol, transmission control protocol) packet mutually; This management server 20 is by HTTP (Hyper Text Transportation Protocol, HTML (Hypertext Markup Language)) connects a client computer 30, realize transmitted in both directions between this client computer 30 and the management server 20, and this client computer 30 is provided with a browser 31, the tcp data bag that this browser 31 transmits in order to receiving management server 20, and the tcp data bag shown by text message, and, input information can be exported with the tcp data bag in order to receive input information.
See also shown in Figure 2ly, its Redirectional system by the serial data of Fig. 1 is reaching, and this reorientation method may further comprise the steps:
Step 101: browser 31 access management servers 20;
Step 102: management server 20 lines are managed server 10;
Step 103: browser 31 judges whether to obtain input information; If then enter step 104; If not, then continue execution in step 103;
Step 104: browser 31 judges whether this input information is to disconnect connecting; If enter step 109; If not, enter step 105;
Step 105: management server 20 is obtained the tcp data bag of transmission according to input information, and the tcp data bag that transmits is sent to by pipe server 10;
Step 106: managed server 10 when receiving the tcp data bag of transmission, obtain the reception serial data according to the tcp data bag that transmits, and obtain corresponding passback serial data according to receiving serial data, will return the UDP message bag that serial data converts passback to again and send to management server 20;
Step 107: management server 20 receives the UDP message bag of passback, and obtains the tcp data bag of passback according to the UDP message bag of passback, and the tcp data bag of passback is sent to browser 31;
Step 108: browser 31 receives the tcp data bag of passback, the output videotex, and return step 103;
Step 109: management server 20 disconnects and the line of being managed server 10.
