As shown in Figure 1, remote white boarding system 100 includes server 101 and 3 electronic whiteboard, that is, electronic whiteboard 102a,
102b and 102c.The quantity of electronic whiteboard is without being limited thereto in practical application.In remote white boarding system 100, if electronic whiteboard
102a, 102b and 102c are in compatibility mode, for example, person's handwriting drawing mode is in, due to the person's handwriting of each electronic whiteboard
Using different numbers (point ID), it is equivalent on the same electronic whiteboard using multiple paintbrushes while is write,
It therefore is not in data exception situation.
But if electronic whiteboard 102a is under person's handwriting drawing mode, and electronic whiteboard 102b is in handwriting erasing mode
Under, in simultaneous display, the drawing data of person's handwriting can be sent to electronic whiteboard 102b through server 101 by electronic whiteboard 102a；
During electronic whiteboard 102a draws person's handwriting, electronic whiteboard 102b can send the erasing data of person's handwriting through server 101
To electronic whiteboard 102a.Under certain conditions, due to Network Transmission Delays etc., it may cause electronic whiteboard 102a and first carry out
The person's handwriting of this terminal draws operation, then executes the handwriting erasing operation of electronic whiteboard 102b；On the other hand, electronic whiteboard 102b is then
It is the person's handwriting drafting operation for first carrying out the handwriting erasing operation of this terminal, then executing electronic whiteboard 102a.In this way, in electronic whiteboard
It is being shown on 102a the result is that first drawing wiping again as a result, and what is shown on electronic whiteboard 102b is then first to wipe to draw again
As a result, both results may be different, which results in the display of each electronic whiteboard is inconsistent.Therefore, traditional skill
Need the operation mode inconsistent to this display result that may cause each electronic whiteboard (hereinafter referred to as mutually abnormal in art
Operation mode) limited, that is, do not allow each electronic whiteboard while being respectively under the operation mode of mutual exception, this
It is poor to have led to operating flexibility.
Based on this, in order to avoid the operation mode to each electronic whiteboard limits, the present invention provides a kind of long-range white
The method of controlling operation thereof of plate system, this method can the server 101 in remote white boarding system 100 as shown in Figure 1 execute.But it answers
When understanding, framework shown in FIG. 1 is a kind of exemplary architecture that can be used for executing technical solution of the present invention, not
As the limitation to technical solution of the present invention.As shown in Fig. 2, this method may include following steps 201 to step 203：
In step 201, the operation information that each electronic whiteboard is sent is received；
Wherein, electronic whiteboard can use electronic whiteboard 102a~102c in remote white boarding system 100 shown in FIG. 1,
But the quantity of electronic whiteboard is not limited to 3 in the embodiment of the present invention, is also possible to 2 perhaps 4 or other quantities.Electronics

It is standby to can include but is not limited to smart phone, computer learning machine, tablet computer, PDA (Personal Digital
Assistant, personal digital assistant) or the electronic equipments such as PC (Personal Computer, personal computer).
Operation described in this step can be person's handwriting and draw operation, handwriting erasing operation, the shifting of person's handwriting zoom operations, person's handwriting
Dynamic operation etc.；Wherein, person's handwriting scaling and the mobile person's handwriting that also may be collectively referred to as of person's handwriting roam.Wherein, roam operation can be divided into office
Portion's roaming and global roaming, part roaming refer to the part operation object on electronic whiteboard (such as：Part person's handwriting) execute roaming
Operation；Overall situation roaming, which refers to, executes roam operation to all operationss object on electronic whiteboard.Electronic whiteboard can be set as
Different operation mode, to execute corresponding operation on electronic whiteboard.It is drawn for example, person's handwriting can be set by electronic whiteboard
Molding formula, so that executing person's handwriting on electronic whiteboard draws operation；Or electronic whiteboard can be set to handwriting erasing mode,
To execute handwriting erasing operation on electronic whiteboard.Each electronic whiteboard may be at different operation modes, each electronics
Operation mode locating for blank is also possible to compatible mode (that is, being not belonging to mutually either mutual abnormal mode
Abnormal mode).By taking remote white boarding system 100 shown in FIG. 1 as an example, wherein electronic whiteboard 102a may be at person's handwriting drafting
Mode, electronic whiteboard 102b may be at handwriting erasing mode, and electronic whiteboard 102c may be at person's handwriting roam mode.
Operation information notifies operation performed in this terminal of other electronic whiteboards for electronic whiteboard.Operation information can be with
Type (for example, person's handwriting draws operation, handwriting erasing operation etc.) including operation, action type can be indicated with number, example
Such as, person's handwriting, which draws action type number 001, indicates that handwriting erasing action type number 002 indicates, and so on.Operation
Information can also include the location information where operation object (in general referring to the person's handwriting on electronic whiteboard), position letter
Ceasing can be indicated with coordinate, can be with the point of some on the display interface of electronic whiteboard (for example, central point of display interface)
Coordinate system is established for coordinate center, and obtains the coordinate of person's handwriting in this coordinate system, as location information.Further, in order to
Simultaneous display is preferably carried out on each electronic whiteboard, can also include the attribute information of operation object, example in operation information
Such as, the color including person's handwriting, thickness and/or line style (e.g., solid line or dotted line) etc..Further, it can also be wrapped in operation information
Operation object ID used in electronic whiteboard is included, for characterizing the electronic whiteboard for executing operation to operation object.For example, operation pair
It for characterizing the person's handwriting is drawn on which electronic whiteboard as ID can be person's handwriting ID (point ID).
The object set of roaming can also be sent if it is local roaming for roam operation, that is, which object be directed to
Execute roam operation；It is roamed if it is the overall situation, then can send global roaming identity information (for characterizing present mode as the overall situation
The instruction information of roam mode)；In addition, the offset and/or pantograph ratio of roaming object can also be sent for roam operation
Example.It can also include page ID in operation information, for characterizing the behaviour executed in one embodiment, it is assumed that there is multiple pages
The page where making.
In step 202, the reception sequence of operation information is obtained；
Reception sequence in this step refers to that server receives the sequence of each operation information.Server is receiving behaviour
After making information, the operation information in addition to received operation information at first can be added to buffer queue according to reception sequence
It is middle to be cached that (operation information being initially received be sent directly to each electronic whiteboard, can also first cache and send out again
It send).Since there are due to network delay etc., the corresponding operation information of the operation first carried out in time may not first be connect by server
It receives.For example, electronic whiteboard 102a, which executes person's handwriting at the t1 moment, draws operation, and person's handwriting is drawn and operates corresponding operation information
It is sent to server 101；Electronic whiteboard 102b executes handwriting erasing operation at the t2 moment, and handwriting erasing is operated corresponding behaviour
Server 101 is sent to as information；Wherein the t1 moment is earlier than the t2 moment.However, due to electronic whiteboard 102a and server 101 it
Between communication link congestion, may cause server 101 be firstly received electronic whiteboard 102b transmission handwriting erasing operation pair
The operation information answered, the person's handwriting for then just receiving electronic whiteboard 102a transmission, which is drawn, operates corresponding operation information.However, nothing
Which electronic whiteboard operation information is first sent by, and server need to only obtain the reception sequence of each operation information, and according to reception
Sequence executes subsequent operation, thus control logic is relatively simple, reduces control complexity.
In step 203, controlling each electronic whiteboard, to execute each operation information respectively according to reception sequence corresponding
Operation.
In one embodiment, as shown in figure 3, can according to the following steps 301 and step 302 control each electronic whiteboard and hold
The each operation information of row：
Step 301：The first operation information for being initially received and having not carried out since operation information, each electricity is controlled
Sub- blank executes corresponding first operation of the first operation information respectively.
Step 302：In the completion information of the first operation for receiving the return of at least one electronic whiteboard, return executes step
Rapid 301, it is finished until the corresponding operation of each operation information is performed both by.
Still it is illustrated by taking remote white boarding system 100 shown in FIG. 1 as an example.Assuming that server 101 receives each operation
The reception sequence of information after arriving first by being followed successively by：What the operation information M1 that electronic whiteboard 102a is sent, electronic whiteboard 102b were sent
The operation information M3 that operation information M2, electronic whiteboard 102c are sent.Then server 101 first controls electronic whiteboard 102a~102c and holds
Row operation information M1, then control control electronic whiteboard 102a~102c and execute operation information M2, finally control electronic whiteboard 102a
~102c executes operation information M3.
In one embodiment, corresponding first operation of the first operation information is executed respectively in each electronic whiteboard of control
Before, the first operation information can also be respectively sent to each electronic whiteboard；Wherein, the first electronic whiteboard is to send the first operation
The electronic whiteboard of information.
In the present embodiment, server 101, can be with before control electronic whiteboard 102a~102c executes operation information M1
Operation information M1 is first sent to control electronic whiteboard 102a~102c.Similarly, server 101 control electronic whiteboard 102a~
Before 102c executes operation information M2, operation information M1 first can be sent to control electronic whiteboard 102a~102c；Server
101 before control electronic whiteboard 102a~102c executes operation information M3, operation information M1 first can be sent to control electricity
Sub- blank 102a~102c.
Since the resolution ratio of each electronic whiteboard is there may be difference, it is respectively sent to by the first operation information
Before each electronic whiteboard, the resolution ratio of each electronic whiteboard can be obtained respectively first, then grasped according to resolution ratio to first
Make to be respectively sent to each electronic whiteboard after information carries out conversion of resolution.
Further, each electronic whiteboard, can also be first by operation information before sending operation information to server
Conversion of resolution is default resolution ratio, can be again pair by default conversion of resolution when server needs to send operation information
Answer the resolution ratio of electronic whiteboard.
Still it is illustrated by taking remote white boarding system 100 shown in FIG. 1 as an example.Assuming that the resolution of electronic whiteboard 102a~102c
Rate is respectively R1, R2 and R3, then server, can be according to electronic whiteboard 102a when operation information M1 is sent to electronic whiteboard M2
Resolution ratio R1 and electronic whiteboard 102b resolution ratio R2 to operation information M1 carry out conversion of resolution, after converting again
Operation information M1 is sent to electronic whiteboard 102b.Further, it is assumed that default resolution ratio is R0, and electronic whiteboard 102a can be first
Conversion of resolution is carried out to operation information M1 according to itself resolution ratio R1 and default resolution ratio R0, is subsequently sent to server 101；
Server, can be according to the resolution for presetting resolution ratio R0 and electronic whiteboard 102b when operation information M1 is sent to electronic whiteboard M2
Rate R2 carries out conversion of resolution to operation information M1, and operation information M1 is sent to electronic whiteboard again after converting
102b。
Technical solution of the present invention is illustrated by taking specific practical application scene as an example below.
It is 2 electronic whiteboards while control sequential figure when operating in one embodiment as shown in Figure 4, in the present embodiment
In, electronic whiteboard 102a and electronic whiteboard 102b are under the mutually operation mode of exception, wherein are in electronic whiteboard 102a
Under person's handwriting drawing mode, for electronic whiteboard 102b is under handwriting erasing mode.Control flow is as follows：
Step 401：The person's handwriting that server 101 receives electronic whiteboard 102a transmission draws operation information M1.
Step 402：Server 101 receives the handwriting erasing operation information M2 of electronic whiteboard 102b transmission, wiping of identifying the handwriting
Except operation information M2 is cached.
Step 403：Server 101 sends control information C1 to electronic whiteboard 102a, and sends and control to electronic whiteboard 102b
Information C1 and person's handwriting processed draw operation information M1；Wherein, control information C1 is for notifying electronic whiteboard 102a and electronic whiteboard
102b executes person's handwriting and draws operation.
Step 404：Electronic whiteboard 102a executes person's handwriting and draws operation.
Step 405：Electronic whiteboard 102b draws operation information M1 according to person's handwriting and executes person's handwriting drafting operation.
Step 406：After electronic whiteboard 102a has executed person's handwriting drafting operation, person's handwriting is sent to server 101 and draws behaviour
Be finished message.
Step 407：Server 101 sends handwriting erasing operation information M2 and control information C2 to electronic whiteboard 102a, and
Control information C2 is sent to electronic whiteboard 102b；Wherein, control information C2 is for notifying electronic whiteboard 102a and electronic whiteboard
102b executes handwriting erasing operation.
Step 408：Electronic whiteboard 102a executes handwriting erasing operation according to handwriting erasing operation information M2.
Step 409：Electronic whiteboard 102b executes handwriting erasing operation.
In above-mentioned steps 409, if electronic whiteboard 102b, which has had not carried out person's handwriting when receiving control information C2, draws behaviour
Make, then continue to execute person's handwriting and draw operation, executes handwriting erasing operation after being finished again.
The control flow of the embodiment of the present invention is not limited to process shown in 401~step 409 of above-mentioned steps, for example, upper
It states in step 406 to step 407, handwriting erasing operation information M2 first can be sent to electronic whiteboard 102a, electronics by server
Blank 102a is when receiving handwriting erasing operation information M2, if having had not carried out person's handwriting draws operation, wiping of first identifying the handwriting
Except operation information M2 is cached, after person's handwriting draws operation completion, just start to execute handwriting erasing operation.In this way, service
Device 101 just executes handwriting erasing without just controlling each electronic whiteboard after waiting electronic whiteboards 102a to execute person's handwriting drafting operation
