Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the embodiment of the present invention is described in further detail.
The method that print data conversion is exported providing in the embodiment of the present invention, Apparatus and system, to be generally a stylus printer for the information output of opertaing device running status and service data in prior art, need manually to remove to judge opertaing device state to the information of device context reader-printer output, understand the technical matters of a large amount of human cost of ancillary cost, propose to gather the print data from opertaing device to printing device, adopt particular algorithm to change to print data, generation can be in long-range demonstration data of consulting, save on-the-spot human cost of consulting result, thereby realize the function of opertaing device being carried out information reform and electronic remote printing in the situation that not affecting equipment security of operation.
The embodiment of the present invention will be described from the design factors of print data conversion output, and the device of this print data conversion output specifically can be integrated in change server.Shown in Figure 1, first embodiment of the present invention system equipment syndeton is described.The embodiment of the present invention is transformed original opertaing device way of output, data acquisition equipment and change server on the basis of original output mode, are increased, between opertaing device and printing device, add a data acquisition equipment, data acquisition equipment is connected to data intercept the circuit of printer from opertaing device, and forwarding the print data being truncated to change server, change server is used for realizing reception data, analyzes the functions such as data, translation data, storage data.In actual applications, data acquisition equipment can be connected to the path between printing device by printing connection and opertaing device, and data acquisition equipment can be connected with change server by ethernet line.
The function below change server being realized, the method by print data conversion output providing in the embodiment of the present invention is specifically described.Shown in Figure 2, the embodiment of the method by print data conversion output providing in the embodiment of the present invention can comprise the following steps:
Step 201: the opertaing device that reception data acquisition equipment collects is sent to the print data of printing device, by print data data writing buffer area.
First the information that data acquisition equipment can adopt the mode of bypass data collection to send to stylus printing to opertaing device is caught, owing to will ensure can not affect the normal work of printing device in image data, so need to print data in the process of printing device in opertaing device transmission, set up a branch node, from the data stream of opertaing device transmission print data, copy a print data, by buffering, strengthen and drive, print data is transferred to data acquisition equipment by the circuit such as photoelectricity isolation, the data that are sent to printer with the correct also guarantee of print data that ensures to intercept do not change, thereby reach correct data intercept and do not affect the requirement that legacy data transmits.
Data acquisition equipment can be transmitted to change server after gathering print data, change server is opened PORT COM and is monitored, in snoop procedure, judge whether to receive valid data, if do not receive that data just continue to monitor, if the data of receiving, just the data data writing buffer zone of receiving, it is the print data that change server can receive opertaing device that data acquisition equipment collects and be sent to printing device, and by print data data writing buffer area, the size of data buffer area can arrange according to practical situations.
Step 202: judge whether print data finishes receiving, if print data does not finish receiving, return to step 201 and continue to receive the opertaing device that collects of data acquisition equipment and be sent to the print data of printing device.
Step 203: if print data finishes receiving, the print data in save data buffer area, and empty data buffer area.
Change server judges in the process of data writing buffer zone whether print data finishes receiving, just continue to receive if do not finished receiving, if finished receiving, just the print data in data buffer is preserved to the data that simultaneously clear data in buffer zone.
Above step is that change server receives data link, in this link, key is real-time and the accuracy of requirement to each data acquisition, the factor such as print data size, delivery time that sends printing device due to opertaing device to is uncertain, need to considering the problems such as frequency acquisition, acquisition time, data integrity, for how judging whether print data finishes receiving will in subsequent embodiment, describe in detail.
Step 204: the print data of preservation is divided into and controls data, character data and view data according to print protocol.
Shown in Figure 3, after data receiver link, enter data-switching link, data-switching link is first carried out initial work, import the print data of preserving, then print data is analyzed, print data is divided into and controls data, character data and view data, then these data-switching are become to intermediate form data, then the output conversion of intermediate form data is generated and shows the data preservation of classifying.
First data-switching link imports the print data that data receiver link is preserved, and then according to stylus printing agreement, the print data importing is divided into and controls data, character data and view data.For example: run into 1B 2A order in the time importing image data time, just represent that print data enters image model, then obtaining print data according to this command format parsing is 1B 2A m n1 n2 d1 d2 ... di, wherein m presentation video output density, n1 n2 indicates how many view data, total columns N=n1+n2*256 of image, di represents the view data of input, for 24 dot patterns, every row need the data of 3 bytes, therefore 3 of columns times is required view data byte number, then extract corresponding data according to view data byte number and be divided into view data, the control commands such as 1B 2A are divided into control data.In like manner, character data is also to separate according to print protocol.
Step 205: according to controlling data, character data or view data are converted to intermediate form data, intermediate form data are carried out to output display at image output area, generate demonstration data corresponding to print data.
Consider that printing device is to print line by line in the time printing, therefore in the time being converted to electronic document demonstration, can be also to show line by line, show before data output being converted to like this, Various types of data can be converted to conveniently and carries out the intermediate data format of output display at image output area, and then progressively change demonstration according to the mode of serial.
In some embodiments of the invention, can comprise according to controlling the specific implementation that character data or view data be converted to intermediate form data by data:
Read corresponding character data or view data according to controlling data order, add in the raw data attribute in intermediate form data, and the data type of character data or view data is added in the data type attribute in intermediate form data;
Determine output position information and the display mode information of character data or view data according to the print command in control data, add to respectively in the positional information attribute and display type attribute in intermediate form data.
Also be that intermediate form data comprise the attributes such as positional information, data type, raw data, display type, character data or view data itself is as the raw data of intermediate form data, data type represents that this raw data is character data or view data, then can for example amplify the print position of the raw data of definite correspondence such as printing, line feed printing according to the print command of controlling in data, according to definite display type such as such as dual density printing of print command, single density printing of controlling in data.
In actual applications, the realization of data-switching link can be: import the print data of preserving; Distribute and control array variable space, data field, array variable space, character data district, array variable space, image data area; According to print protocol, the print data importing is separated, then the data that separate are deposited in respectively and control data field array variable, character data district array variable, image data area array variable; Distribute array variable space, intermediate form data field, intermediate form data have the following attribute: positional information, data type, raw data, display type; By controlling data array variable order, corresponding character data or view data are deposited in the array variable raw data attribute of intermediate form data field, according to controlling data command, corresponding positional information, data type, display type are also deposited in the array variable attribute of intermediate form data field simultaneously.Owing to having view data and character data in print data simultaneously, so can not, by the mode of text, can only show by the mode of picture, can show data according to the conversion in painting canvas of intermediate form data field data order in the time showing data.
Shown in Figure 4, be the result schematic diagram that the embodiment of the present invention generates demonstration data corresponding to print data.Show that by the file after conversion result compares with printing device print file, character and picture material show correct, and file layout structure can be consistent, and sharpness is better than the result of printing device, and slewing rate is far away higher than the print speed of printing device.
Like this, demonstration data can be consulted for long-range, and user can conduct interviews by united portal or client-side program, and user can consult demonstration data by browser mode or client.The embodiment of the present invention is sent to the print data of printing device by gathering opertaing device, the print data collecting is converted to character information and image information, and carry out output display by these information at image output area, generate demonstration data corresponding to described print data, the demonstration data that generate can long-rangely be consulted, no longer need the Output rusults to opertaing device to scene to consult, can save a large amount of human costs.
Above-described embodiment has illustrated real-time and the accuracy that need to ensure to receive print data in reception data link, and in DRP data reception process, how to judge that whether print data receives complete is a difficult point, this is there is no obvious opening flag and end mark because opertaing device sends to the print data of printing device, is difficult to judge whether to receive a complete packet; Meanwhile, it is serial data that opertaing device sends to the print data of printing device, and data are transmissions, will cause whole Data Analysis failure if wherein there is a data to make a mistake.
For this reason in some embodiments of the invention, propose the specific implementation that judges whether print data finishes receiving, can comprise:
Judge whether to exceed threshold time and do not continue to receive print data;
Judge that whether data buffer area is full;
Judge whether to receive default print command;
Do not continue to receive that print data, data buffer area are full or receive default print command if exceed threshold time, determining that print data finishes receiving; If in threshold time, continue to receive print data, data buffer area less than and do not receive default print command, determine that print data does not finish receiving.
Also judge the tactful following points whether print data finishes receiving:
The first, time strategy.Because sending to a complete print data of printing device, opertaing device can within the relatively short time, send continuously, this threshold time, in reality test, find it is generally in 10 seconds, so, for example, if wait for that exceeding threshold time (10 seconds) also does not continue to receive print data, just thinks and has received a complete print data.
The second, buffer zone strategy.Can set in advance data buffer size, when data buffer data are completely time, just think a complete print data, then receive a print data more, the full content before just preserving in data buffer, then empties data buffer.For example, data buffer size is set to print the print data size of one page content, and data buffer area is full thinks that a complete print data preserves.
The 3rd, print command strategy.If receive OA, OB, OC, OD, when the print commands such as 4A, represents that next print data starts, and the data of data buffer can be preserved, and then empties data buffer.
In order to reach the effect of correct reception print data, can tackle according to above-mentioned strategy, in actual use procedure, also can constantly adjust simultaneously.
In some embodiments of the invention, the method by print data conversion output providing in the embodiment of the present invention can also comprise:
If print data finishes receiving, judge in print data whether comprise default Data Identification, if so, the print data in save data buffer area, and empty data buffer area, and if not, outputting alarm information.
Also need the data to receiving to verify, whether the data that judgement is received are correct, the impact that can be subject to various factors due to print data in the process of transmission causes loss of data or mistake, because sending to the print data of printing device, opertaing device there is no effect position again, therefore can not carry out by effect position the correctness of verification msg, the mode that adopted is in embodiments of the present invention to receive that whether after print data, can carry out verification msg according to the fixing Data Labels of some of print data correct, for example, judge whether to comprise default control word etc., if the data of receiving do not have these fixing Data Labelses, what just explanation was received is misdata, need to carry out alarm prompt.
In addition, in some embodiments of the invention, can also automatically audit showing data according to data integrity strategy, data stipulations strategy, data verification strategy, the demonstration data that examination & verification is passed through are carried out Macro or mass analysis.
Like this, the embodiment of the present invention is sent to the print data of printing device by gathering opertaing device, the print data collecting is converted to character information and image information, and carry out output display by these information at image output area, generate demonstration data corresponding to described print data, the demonstration data that generate can long-rangely be consulted, and no longer need the Output rusults to opertaing device to scene to consult, and can save a large amount of human costs.

Shown in Figure 6, what in the embodiment of the present invention, also provide is a kind of by the system of print data conversion output, can comprise:
Change server 601 and data acquisition equipment 602.
Wherein, data acquisition equipment, bypass is connected on the path between opertaing device and printing device, is sent to the print data of printing device for gathering opertaing device, and print data is sent to change server.
Change server can be the device that print data conversion is exported in above-described embodiment.
When opertaing device transmits print data to printing device, what adopt is RS-232C serial communication bus, and RS-232C interface is the EIA of EIA (Electronic Industries Association) and the standard for serial communication of combining the common formulation of Bell System, modulator-demodular unit producer and terminal manufacturer.Because RS232 is single-ended input and output, when diplex operation, at least need digital ground wire, send line and receive three lines of line (asynchronous transmission), can also add other control line and complete the functions such as synchronous.Exist the transmission cable length need to be lower than 50 feet, noise and can not suppress the problems such as common mode interference altogether, so when the mode that adopts bypass to gather, easily cause the problem that receives error in data when transmission line is greater than 50 feet.
In order to address this problem, in some embodiments of the invention, the system by print data conversion output providing in the embodiment of the present invention can also comprise buffer circuit, for reducing the interference of data acquisition equipment to the path between opertaing device and printing device.The connected mode of buffer circuit has at least following two kinds:
Shown in Figure 7, be the first line interface mode, buffer circuit can comprise photoisolator, and one end of photoisolator is connected with the path between opertaing device and printing device, and the other end of photoisolator is connected with data acquisition equipment.This mode is generally used in the situation of short range transmission circuit, carrying out when bypass gathers for example, having added photoelectricity xegregating unit at data acquisition equipment (gathering adapter) front end, has solved the impact of bypass collection on original circuit.

In the time carrying out long-distance transmissions, adopt the mode of RS-232C in conjunction with RS-485, strengthen the flexible and reliability of communication bus.The maximum transmission distance standard value of RS-485 interface is 4000 feet, in fact can reach 3000 meters, and RS-232C interface only allows to connect 1 transceiver, i.e. single station ability in bus in addition.And RS-485 interface is to allow to connect nearly 128 transceivers in bus, there is multistation ability, can utilize so single RS-485 interface to set up easily device network.Because RS-485 interface has good noise immunity, the long above-mentioned advantage such as transmission range and multistation ability.
By special converter, RS-232C signal is converted to RS-485 signal, again RS-485 signal is converted to RS-232C signal and send to printing device, in the time that image data equipment is not supported RS-485 signal, also need to convert RS-485 signal to RS-232C signal and send to image data equipment, so just greatly improved reliability and the accuracy of data transmission procedure.
The embodiment of the present invention not only can realize the conversion output of the print data to separate unit opertaing device, also can concentrate and receive and change in real time output the print data of many opertaing devices simultaneously.Shown in Figure 9, be the system embodiment of the another kind of print data conversion output that provides in the embodiment of the present invention.
Data acquisition equipment (for example gathering adapter) can extract the print data of many opertaing devices simultaneously, if opertaing device quantity is many, also can configure many data acquisition equipments and gather, the change server that then these data acquisition equipments can be pushed to appointment the print data collecting by Ethernet by configuration is analyzed, changes and stores.And manage, configuration, data message can deposit database server in, then by client-side program and the WEB program of exploitation, these information carried out to unified Management and application, user can be by the long-range demonstration data of consulting after conversion of client.
Data acquisition equipment (for example gathering adapter) has the function of multi pass acquisition, and generally gathering adapter has 8 tunnels, 16 tunnels, the 32 several models in tunnel, can gather 8 tunnels, 16 tunnels, 32 circuit-switched data simultaneously; Distribute a port can in collection adapter each acquisition interface, be that different acquisition interface possesses different port numbers, gather like this adapter and send when data and this port information can be sended over to change server, change server can know that what receive is the raw data of which opertaing device like this.
