Background

In 1963, a research group at the institute of technology and technology of Massachusetts published an article on computer aided design technology at the conference of computer unions in the United states. After more than 50 years of development, the current CAD technology has become mature, and mainstream CAD tools represented by CATIA, NX, Creo and the like are formed.

In recent years, with the continuous development of cloud technology, cloud platforms such as amazon cloud and aristoloc have gradually emerged. The cloud platform has the advantage of dynamic resource allocation, and gradually clouding the CAD tools becomes the development direction of the next generation of CAD products. Further, as large-scale and complex design applications are increasing at present, requirements for collaborative design are also gradually increasing. At present, the design result is not stored locally in the cloud CAD technology, so that the existing process of transmitting the design result needs to be carried out when a design task is reopened every time, and data transmission needs to be carried out through a server outlet of a cloud end every time of transmission, so that pressure is brought to the outlet bandwidth of a cloud platform, and the data transmission efficiency of the cloud platform is reduced.

Therefore, how to provide a method to reduce the access to the cloud platform and improve the data efficiency of the cloud platform is an important issue to be solved in the industry.

Fig. 2 is a schematic flow chart of a cloud platform-based collaborative modeling method according to an embodiment of the present invention, and as shown in fig. 2, the cloud platform-based collaborative modeling method provided by the present invention includes:

s201, receiving request information for starting a collaborative modeling task, which is sent by a client;

specifically, when a collaborative modeling task needs to be performed, a client may send request information for starting the collaborative modeling task to the modeling control server, and the modeling control server may receive the request information for starting the collaborative modeling task.

S202, if the fact that the collaborative modeling task is started on the collaborative management server is judged and known, determining a client end in communication connection with the client end according to a first queue number or a second queue number of the client end which has started the collaborative modeling task;

specifically, after receiving the request information for starting the collaborative modeling task, the modeling control server queries and judges whether the collaborative modeling task is already started, and if a collaborative modeling management server runs the collaborative modeling task, it indicates that the collaborative modeling task is already started and there is a client that has already started the collaborative modeling task. The client that has started the collaborative modeling task may have a record in the modeling control server, the modeling control server queries and obtains a first queue number or a second queue number of the client that has started the collaborative modeling task, and determines, according to the first queue number or the second queue number of the client that has started the collaborative modeling task, with which client that has started the collaborative modeling task the client should be in communication connection, and the modeling control server may obtain an IP address of the client that has started the collaborative modeling task, which is in communication connection with the client. The first queue numbers are preset according to the priority of the corresponding clients, and the first queue numbers corresponding to the clients with higher priorities are ranked more ahead; the second queue number is allocated to the client that has started the collaborative modeling task according to the priority corresponding to the client that has started the collaborative modeling task and the start time of the collaborative modeling task, the second queue number of the client with higher priority is ranked at the front, and the second queue numbers of the clients with earlier start time are ranked at the front if the priorities are the same; all clients of the collaborative modeling task and their respective priorities are preset.

For example, the collaborative modeling task corresponds to 5 clients, each of the clients is identified as 1#, 2#, 3#, 4# and 5#, the priority of the 1# client is high, the priority of the 2# client is medium, and the priorities of the 3#, 4# and 5# clients are low, when the first queue number is preset according to the priorities of the 5 clients, the first queue number of the 1# client is set to 01, the first queue number of the 2# client is set to 02, the priorities of the 3#, 4# and 5# clients are the same, the corresponding first queue numbers can be randomly set, the first queue number of the 3# client can be set to 03, the first queue number of the 4# client is set to 04, and the first queue number of the 3# client is set to 05, so as to obtain the 1#, 2#, and 5#, respectively, The first queue numbers of the 3#, 4# and 5# clients are ranked 01, 02, 03, 04 and 05, and the first queue numbers of the high-priority clients are ranked first.

For example, 3 clients have started the collaborative modeling task, and three clients are identified as 6#, 7# and 8#, where the 7# client starts the collaborative modeling task at the earliest time and the preset priority is the highest, the 6# client starts the collaborative modeling task earlier than the 8# client, but the 6# client has a priority lower than the 8# client, and the 8# client has a priority lower than the 7# client. Based on the above information, when the modeling control server allocates the second queue number to the client that has started the collaborative modeling task, the 7# client starts the collaborative modeling task at the earliest time and allocates the second queue number 01 first, when the 6# client starts the collaborative modeling task, the 6# client allocates the second queue number 02 because the priority of the 6# client is lower than that of the 7# client, the 8# client starts the collaborative modeling task later than that of the 6# client, the 8# client allocates the second queue number 02 because the priority of the 8# client is higher than that of the 6# client, and the second queue number of the 6# client is reallocated as 03.

S203, sending the IP address of the client side which carries out communication connection to the client side so that the client side can obtain the relevant information of the collaborative modeling task;

Specifically, after determining a client (hereinafter, referred to as a communication connection client) that has opened the collaborative modeling task and is in communication connection with the client, the modeling control server sends an IP address of the communication connection client to the client, and the client may receive the IP address and establish communication connection with the communication connection client according to the IP address, so that information related to the collaborative modeling task, for example, a three-dimensional model of the collaborative modeling task stored by the communication connection client, may be obtained from the communication connection client. And in the clients for starting the collaborative modeling task, the client with the first queue number or the second queue number which is sequenced most in front establishes communication connection with the collaborative modeling management server.

For example, the clients respectively identified as 1#, 2#, 3#, 4# and 5# correspond to the same collaborative modeling task a and all start the collaborative modeling task, the first queue numbers of the 1#, 2#, 3#, 4# and 5# clients are ordered as 01, 02, 03, 04 and 05, and the first queue number of the 1# client is ordered most forward, so that the 1# client with the first queue number of 01 establishes a communication connection with the collaborative modeling management server, and the 2#, 3#, 4# and 5# clients do not establish a communication connection with the collaborative modeling management server, so as to reduce access to the collaborative modeling management server and reduce the bandwidth pressure of the collaborative modeling management server.

The clients with the identifications of 6#, 7# and 8# open the same collaborative modeling task B, the second queue numbers corresponding to the 6#, 7# and 8# clients are 03, 01 and 02 respectively, the second queue numbers of the 7# client are ranked most forward, then the 7# client with the second queue number of 01 establishes communication connection with the collaborative modeling management server, and the 6# and 8# clients do not establish communication connection with the collaborative modeling management server.

According to the cloud platform-based collaborative modeling method, the modeling control server can receive the request information for starting the collaborative modeling task sent by the client, after the collaborative modeling task is judged and known to be started on the collaborative modeling management server, the client which is in communication connection with the client and has started the collaborative modeling task is determined according to the first queue number or the second queue number of the client which has started the collaborative modeling task, the client can obtain the relevant information of the collaborative modeling task, the access to the collaborative modeling management server is reduced, the bandwidth pressure of the collaborative modeling management server is reduced, and the data transmission efficiency of the cloud platform is improved.

On the basis of the foregoing embodiments, further, the determining, according to the first queue number of the client that has started the collaborative modeling task, the client that is in communication connection with the client, and sending the IP address of the client that is in communication connection to the client includes:

according to the first queue number of the client which has started the collaborative modeling task and the first queue number of the client, determining the client which is in communication connection with the client and sending the IP address of the client which is in communication connection to the client, so that the client establishes communication connection with the client which is in communication connection.

Specifically, when the collaborative modeling task is started, the modeling control server may query, according to the client that has started the collaborative modeling task, a first queue number of the client that has started the collaborative modeling task, and may also query the first queue number of the client. The modeling control server queries and obtains a first queue number adjacent to the first queue number of the client according to the first queue number of the client, wherein the first queue number is adjacent to the first queue number of the client, and the client which opens the collaborative modeling task and corresponds to the first queue number adjacent to the first queue number of the client is the communication connection client. It is understood that the first queue number and the corresponding client may be stored on the modeling control server in a table form to facilitate querying.

For example, clients with the numbers 1#, 2#, 3#, 4# and 5# of the clients are set to correspond to the same collaborative modeling task a, wherein the 2# and 4# clients have started the collaborative modeling task a, and the modeling control server stores the first queue numbers 01, 02, 03, 04 and 05 of the 1#, 2#, 3#, 4# and 5# clients. If the modeling control server receives request information for starting the collaborative modeling task A sent by the 1# client and judges that the collaborative modeling task A is started, the first queue numbers of the 2# and 4# clients are obtained through query and are respectively 02 and 04, and the first queue number of the 1# client is obtained through query and is 01. The modeling control server compares the first queue number 01 with the first queue number 02 to obtain a result, the first queue number 01 is adjacent to the first queue number 02, the client 2# corresponding to the first queue number is the communication connection client, and the client 1# needs to establish communication connection with the client 2 #. After the 1# client starts the collaborative modeling task a, since the first queue number 01 is the most ranked of the first queue numbers 01, 02, and 04, the modeling control server sends the IP address of the collaborative modeling management service running the collaborative modeling task a to the 1# client, and the 1# client receives the IP address and establishes communication connection with the collaborative modeling management service running the collaborative modeling task a. The # 2 client may interrupt the communication connection with the co-modeling management service running the co-modeling task a.

If the modeling control server receives request information for starting the collaborative modeling task A sent by the 3# client and judges that the collaborative modeling task A is started, the first queue numbers of the 2# and 4# clients are obtained through query and are respectively 02 and 04, and the first queue number of the 3# client is obtained through query and is 03. The modeling control server compares the first queue number 03, the first queue number 02 and the first queue number 04 to obtain a result, the first queue number 03 is adjacent to the first queue number 02, the first queue number 03 is adjacent to the first queue number 04, the client 2# client corresponding to the first queue number 02 and the client 4# client corresponding to the first queue number 04 are the communication connection clients, and the client 3# needs to establish communication connection with the client 2# and the client 4# respectively.

If the modeling control server receives request information for starting the collaborative modeling task A sent by the 5# client and judges that the collaborative modeling task A is started, the first queue numbers of the 2# and 4# clients are obtained through query and are respectively 02 and 04, and the first queue number of the 5# client is obtained through query and is 05. The modeling control server compares the first queue number 05, the first queue number 02 and the first queue number 04 to obtain a result, the first queue number 05 is adjacent to the first queue number 04, the client 4# client 4 corresponding to the first queue number 04 is the communication connection client, and the 5# client needs to establish communication connection with the 4# client.

Fig. 3 is a schematic flowchart of a collaborative modeling method based on a cloud platform according to another embodiment of the present invention, and as shown in fig. 3, on the basis of the foregoing embodiments, further determining, according to a second queue number of a client that has started the collaborative modeling task, a client that has started the collaborative modeling task and is in communication connection with the client includes:

s2021, comparing the priority of the client with the priority of the client which opens the collaborative modeling task according to the second queue number of the client which opens the collaborative modeling task and the sequence of the second queue number of the client which opens the collaborative modeling task;

specifically, when the collaborative modeling task is already started, the client that has already started the collaborative modeling task has already been assigned the second queue number, and the modeling control server may store the client that has already started the collaborative modeling task and the corresponding second queue number locally; the modeling control server locally inquires a second queue number of the client which has started the collaborative modeling task according to the client which has started the collaborative modeling task, and compares the priority of the client with the priority of the client which has started the collaborative modeling task according to the sequence of the second queue number of the client which has started the collaborative modeling task. The priority of the client and the priority of the client which has started the collaborative modeling task are preset, and the modeling control server can obtain the priority through query.

S2022, if the priority of the client is judged to meet a first preset condition, a second preset condition or a third preset condition, determining the client which is in communication connection with the client and has started the collaborative modeling task, and setting a second queue number of the client;

the first preset condition is that the priority of the client is greater than or equal to the priority of the client with the first queue number in the second queue number order, and correspondingly, the determining the client which is in communication connection with the client and has started the collaborative modeling task, and the setting the second queue number of the client includes: the client with the first queue number in the sequencing order is the client which is in communication connection with the client and has started the collaborative modeling task, and the second queue number of the client is set as the second queue number of the client with the first queue number in the sequencing order;

the second preset condition is that the priority of the client is less than the priority of the client with the second queue number ranked earlier in two adjacent clients with the collaborative modeling task started in the second queue number, and is greater than or equal to the priority of the client with the second queue number ranked later, and accordingly, the determining the client with the collaborative modeling task started, which is in communication connection with the client, and setting the second queue number of the client includes: the client with the first queue number and the client with the second queue number and the later queue number are clients which are in communication connection with the client and start the collaborative modeling task, and the second queue number of the client is set as the second arrangement number of the client with the second queue number and the later queue number;

the third preset condition is that the priority of the client is smaller than the priorities of all clients already starting the collaborative modeling task, and accordingly, the determining the client already starting the collaborative modeling task in communication connection with the client and setting the second queue number of the client includes: and the client with the second queue number for sequencing the last bit is the client which is in communication connection with the client and has started the collaborative modeling task, and the second queue number of the client is set as the new last bit of the second queue number for sequencing.

Specifically, the modeling control server compares the priority of the client with the priority of the client that has started the collaborative modeling task, if the priority of the client meets a first preset condition, that is, the priority of the client is greater than or equal to the priority of the client with the first queue number in the second queue number ordering, the client with the first queue number in the second queue number ordering is the client that has started the collaborative modeling task and is in communication connection with the client, and the modeling control server sets the second queue number of the client as the second queue number of the client with the first queue number in the second queue number ordering, and then updates the second queue number of the client that has started the collaborative modeling task.

If the priority of the client meets a second preset condition, namely the priority of the client is smaller than the priority of the client with the second queue number in the two adjacent clients which start the collaborative modeling task and are ranked in the front in the second queue number, and is greater than or equal to the priority of the client with the second queue number in the back order, the client with the second queue number in the front order and the client with the second queue number in the back order are the clients which are in communication connection with the client and have started the collaborative modeling task, the modeling control server sets a second queue number of the client as a second ranking number of a client ranked further back than the second queue number, and then updating a second queue number of the client which opens the collaborative modeling task and is ranked later than a second ranking number of the client ranked later than the second queue number.

And if the priority of the client meets a third preset condition, namely the priority of the client is smaller than the priorities of all clients already starting the collaborative modeling task, the last client in the second queue number ordering order is the client already starting the collaborative modeling task and in communication connection with the client, the modeling control server sets a second queue number of the client, and the second queue number of the client becomes the new last in the second queue number ordering after being closer to the second queue number ordering of the last client in the second queue number ordering.

For example, the clients respectively identified as 6#, 7#, 8# and 9# correspond to the same collaborative modeling task B, the 6#, 7# and 8# clients have started the collaborative modeling task B, the priorities of the 6#, 7# and 8# clients are preset, the priority of the 7# client is higher than that of the 8# client, and the priority of the 8# client is higher than that of the 6# client. The 6#, 7# and 8# clients have been assigned the second queue number, the second queue number for the 6# client is 03, the second queue number for the 7# client is 01, and the second queue number for the 8# client is 02. The 9# client also presets a priority, when the modeling control server receives request information for starting the collaborative modeling task B sent by the 9# client and judges that the collaborative modeling task B is already started, the 7# client, the 8# client and the 6# client firstly query and obtain the priority of the 7# client and the priority of the 9# client according to the sequence of the second queue numbers of the 6# client, the 7# client and the 8# client, and compare the priority of the 9# client with the priority of the 7# client.

If the priority preset by the # 9 client is higher than that of the # 7 client, the # 7 client is the communication connection client, and the # 9 client needs to establish a communication connection with the # 7 client to obtain the relevant information of the collaborative modeling task B. And the modeling control server sets the second queue number of the 9# client to be 01, updates the second queue numbers of the 7#, 8# and 6# clients, sets the second queue number of the 7# client to be 02, sets the second queue number of the 8# client to be 03 and sets the second queue number of the 6# client to be 04. After the 9# client starts the collaborative modeling task B, since the second queue number 01 is the most front queue number of the second queue numbers 01, 02, 03, and 04, the modeling control server will send the IP address of the collaborative modeling management service running the collaborative modeling task B to the 9# client, and the 9# client will receive the IP address and establish communication connection with the collaborative modeling management service running the collaborative modeling task B. The client # 7 interrupts the communication connection with the co-modeling management service running the co-modeling task B.

If the priority of the 9# client is lower than that of the 7# client, the priority of the 9# client is compared with that of the 8# client, and if the priority of the 9# client is lower than that of the 8# client and higher than that of the 6# client, the 6# client and the 8# client are the communication connection clients, and the 9# client needs to establish a communication connection with the 6# client and the 8# client to obtain the relevant information of the collaborative modeling task B. And the modeling control server sets the second queue number of the 9# client to 03, updates the second queue number of the 6# client, and sets the second queue number of the 6# client to 04.

If the preset priority of the 9# client is lower than the priorities of the 6# client, the 7# client and the 8# client, and the second queue number of the 6# client is ranked by the last bit, the 6# client is the communication connection client, and the 9# client needs to establish communication connection with the 6# client to obtain the relevant information of the collaborative modeling task B. And the modeling control server sets the second queue number of the 9# client to 04, and the second queue number becomes the new last ordered bit of the second queue number.

Fig. 4 is a schematic flowchart of a cloud platform-based collaborative modeling method according to another embodiment of the present invention, and as shown in fig. 4, on the basis of the foregoing embodiments, the cloud platform-based collaborative modeling method according to the present invention further includes:

s204, receiving request information for finishing the collaborative modeling task, which is sent by the client;

specifically, when the collaborative modeling task needs to be terminated, the client sends request information for terminating the collaborative modeling task to the modeling control server, and the modeling control server receives the request information for terminating the collaborative modeling task.

And S205, if the client is judged to be not the client which requests to end the collaborative modeling task, updating the second sequence number of the client with the second queue number being ranked later than the second queue number of the client.

Specifically, since each of the clients starts the collaborative modeling task, the modeling control server performs recording, and after receiving the request information for ending the collaborative modeling task, the modeling control server queries the recording, if the client is not the last request for ending the collaborative modeling task, that is, other clients are performing the collaborative modeling task. And the modeling control server searches the client with the second queue number which is more rear than the second queue number of the client according to the second queue number of the client, and updates the second queue numbers corresponding to the client. It can be understood that, if the client is the last client requesting the end of the collaborative modeling task, the client uploads the local relevant information of the collaborative modeling task to the collaborative modeling management server before sending the request information for ending the collaborative modeling task, and the collaborative modeling management server stores the relevant information of the collaborative modeling task. And after receiving the request information for finishing the collaborative modeling task, the modeling control server closes the collaborative modeling task operated by the collaborative modeling management server to release system resources.

For example, the clients identified as 6#, 7#, and 8# correspond to the same collaborative modeling task B, and the clients identified as 6#, 7#, and 8# have started the collaborative modeling task B and are assigned the second queue numbers, respectively, where the second queue number of the client identified as 6# is 03, the second queue number of the client identified as 7# is 01, and the second queue number of the client identified as 8# is 02. If the 8# client sends the request information for ending the collaborative modeling task B to the modeling control server, after receiving the request information for ending the collaborative modeling task B, the modeling control server judges that the 7# and 6# clients are still performing the collaborative modeling task B, the 7# client is not the client that has requested to end the collaborative modeling task at the last time, and the modeling control server updates the second queue number of the 6# client to be 02 because the second queue number of the 6# client is sequenced after the 8# client.

Fig. 5 is a schematic flowchart of a collaborative modeling method based on a cloud platform according to still another embodiment of the present invention, and as shown in fig. 5, the collaborative modeling method based on the cloud platform provided by the present invention includes:

s501, sending request information for starting a collaborative modeling task to a modeling control server;

S502, receiving an IP address of a client which is communicated with the local and has opened the collaborative modeling task and sent by the modeling control server, establishing communication connection with the client which is communicated with the local and has opened the collaborative modeling task according to the IP address, and obtaining related information of the collaborative modeling task;

the IP address is sent after the modeling control server judges that the collaborative modeling task is started on the collaborative management server, and determines the client which is in communication connection with the local and has started the collaborative modeling task according to the first queue number or the second queue number of the client which has started the collaborative modeling task;

Specifically, the client receives an IP address of a client that has opened the collaborative modeling task and is in communication connection with a local node, which is sent by the modeling control server, and establishes communication connection with the client that has opened the collaborative modeling task according to the IP address, so as to obtain information related to the collaborative modeling task, for example, a three-dimensional model of the collaborative modeling task stored by the communication connection client;

after receiving the request information for starting the collaborative modeling task, the modeling control server inquires and judges whether the collaborative modeling task is started or not, and if a collaborative modeling management server runs the collaborative modeling task, the modeling control server indicates that the collaborative modeling task is started and a client which starts the collaborative modeling task exists. The client that has started the collaborative modeling task may have a record in the modeling control server, the modeling control server queries and obtains a first queue number or a second queue number of the client that has started the collaborative modeling task, and determines, according to the first queue number or the second queue number of the client that has started the collaborative modeling task, with which client that has started the collaborative modeling task the client should be in communication connection, and the modeling control server may obtain an IP address of the client that is in communication connection with the client, and then send the IP address to the client.

The first queue numbers are preset according to the priority of the corresponding clients, and the first queue numbers corresponding to the clients with higher priorities are ranked more ahead; the second queue number is allocated to the client that has started the collaborative modeling task according to the priority corresponding to the client that has started the collaborative modeling task and the start time of the collaborative modeling task, the second queue number of the client with higher priority is ranked at the front, and the second queue numbers of the clients with earlier start time are ranked at the front if the priorities are the same; all clients of the collaborative modeling task and the corresponding priorities are preset; and in the clients for starting the collaborative modeling task, the client with the first queue number or the second queue number which is sequenced most in front establishes communication connection with the collaborative modeling management server.

The IP address is sent after the modeling control server judges that the collaborative modeling task is started on the collaborative management server, and determines the client which is in communication connection with the local and has started the collaborative modeling task according to the first queue number of the client which has started the collaborative modeling task, and the IP address comprises: and the IP address is sent after the modeling control server determines the client which is in communication connection with the local and has started the collaborative modeling task according to the first queue number of the client which has started the collaborative modeling task and the local first queue number.

Specifically, the client receives the IP address of the client that has opened the collaborative modeling task and performs communication connection sent by the modeling control server, and establishes communication connection with the client that has opened the collaborative modeling task and performs communication connection according to the IP address. When the collaborative modeling task is started, the modeling control server can query the first queue number of the client which has started the collaborative modeling task according to the client which has started the collaborative modeling task, and can also query the first queue number of the client. The modeling control server inquires and judges the first queue number adjacent to the first queue number of the client according to the first queue number of the client, wherein the client which is corresponding to the first queue number adjacent to the first queue number of the client and opens the collaborative modeling task is the client which is in communication connection with the local and has opened the collaborative modeling task. The modeling control server may obtain an IP address of the client that has started the collaborative modeling task and is in communication with the local, and send the IP address to the client. It is understood that the first queue number and the corresponding client may be stored on the modeling control server in a table form to facilitate querying.

The IP address is sent by the modeling control server after determining that the collaborative modeling task is started on the collaborative modeling management server and determining, according to the second queue number of the client that has started the collaborative modeling task, the client that has started the collaborative modeling task and is in communication connection with the local, and includes: and the corresponding IP address is sent after the modeling control server compares the local priority with the priority of the client which opens the collaborative modeling task according to the second queue number of the client which opens the collaborative modeling task and the sequence of the second queue number, and determines the client which opens the collaborative modeling task and is in communication connection with the local after judging that the local priority meets a first preset condition, a second preset condition or a third preset condition.

Specifically, when the collaborative modeling task is already started, the client that has already started the collaborative modeling task is already assigned the second queue number, and the modeling control server may store the client that has already started the collaborative modeling task and the corresponding second queue number; the modeling control server inquires a second queue number of the client which has started the collaborative modeling task according to the client which has started the collaborative modeling task, and compares the priority of the client with the priority of the client which has started the collaborative modeling task according to the sequence of the second queue number of the client which has started the collaborative modeling task.

And if the priority of the client meets a first preset condition, namely the priority of the client is greater than or equal to the priority of the client with the first queue number in the second queue number ordering, the client with the first queue number in the second queue number ordering is the client which is in communication connection with the client and has started the collaborative modeling task. And the modeling control server acquires the IP address of the client with the first queue number in the sequence, and sends the IP address of the client with the first queue number in the sequence to the client. And the client receives the IP address of the client with the first queue number in the sequence of the second queue number, and establishes communication connection with the client with the first queue number in the sequence of the second queue number according to the IP address, so that the relevant information of the collaborative modeling task can be obtained from the client with the first queue number in the sequence of the second queue number.

And if the priority of the client meets a second preset condition, that is, the priority of the client is less than the priority of the client with the front-ranked second queue number in two adjacent clients which have started the collaborative modeling task and is greater than or equal to the priority of the client with the back-ranked second queue number, the client with the front-ranked second queue number and the client with the back-ranked second queue number are clients which have started the collaborative modeling task and are in communication connection with the client. The modeling control server sends the IP addresses of the client side with the first queue number in the front of the sequence and the client side with the second queue number in the back of the sequence to the client side, the client side receives the IP addresses of the client side with the first queue number in the front of the sequence and the client side with the second queue number in the back of the sequence, communication connection is established between the IP address of the client side with the first queue number in the front of the sequence according to the second queue number, and communication connection is established between the IP address of the client side with the second queue number in the back of the sequence according to the second queue number. The client may obtain the relevant information of the collaborative modeling task from the client with the first queue number in the ranking order, and may obtain the relevant information of the collaborative modeling task from the client with the second queue number in the ranking order.

And if the priority of the client meets a third preset condition, namely the priority of the client is less than the priorities of all the clients which start the collaborative modeling task, the client with the last queue number and the last rank is the client which is in communication connection with the client and starts the collaborative modeling task. And the modeling control server acquires the IP address of the client with the last sorted second queue number and sends the IP address to the client, and the client receives the IP address and establishes communication connection with the client with the last sorted second queue number according to the IP address so as to acquire the related information of the collaborative modeling task.

On the basis of the foregoing embodiments, further, the cloud platform-based collaborative modeling method provided by the present invention further includes:

and sending the first updating information of the collaborative modeling task to the client which is in communication connection with the local.

Specifically, the client receives an input of a designer, and changes related information of the collaborative modeling task to obtain first updated information of the collaborative modeling task, for example, a new three-dimensional model is added. The client side can send the first updating information of the collaborative modeling task to the client side which is in communication connection with the local, and the client side which is in communication connection with the local can receive the first updating information, so that the consistency of a plurality of designers on design can be ensured. The first updating information is directly transmitted among the clients, and a collaborative modeling management server is not needed, so that system resources of the cloud platform are saved.

and receiving second updating information of the collaborative modeling task sent by the client side which is in communication connection with the local area.

Specifically, on the client in communication connection with the local, the related information of the collaborative modeling task may be changed to form second update information of the collaborative modeling task, the client in communication connection with the local sends the second update information to the client, and the client may receive the second update information and store the second update information. The second updating information is directly transmitted among the clients, so that a collaborative modeling management server is not needed, and system resources of the cloud platform are saved.

and if the second updating information is judged to be conflicted with the local information and the sequencing of the first queue number of the client from which the second updating information comes is positioned before the local first queue number or the sequencing of the second queue number is positioned before the local second queue number, replacing the corresponding local information with the second updating information conflicted with the local information.

Specifically, after the client receives the second update information, the second update information may conflict with local information. The client compares the first queue number of the client from which the second updating information comes with the local first queue number, and if the ordering of the first queue number of the client from which the second updating information comes is before the local first queue number, the corresponding local information is replaced by the second updating information which conflicts with the local information, and the first queue number of the client from which the second updating information comes and the local first queue number can be obtained from the modeling control server; or the client compares the second queue number of the client from which the second updating information comes with a local second queue number, and if the ordering of the second queue number of the client from which the second updating information comes is before the local second queue number, the corresponding local information is replaced by the second updating information conflicting with the local information, and the second queue number of the client from which the second updating information comes and the local second queue number can be obtained from the modeling control server.

and if the communication connection with the client end which is in communication connection with the local is judged to be disconnected, acquiring the IP address of the standby client end and establishing the communication connection.

Specifically, the client does not receive a feedback message of the client in communication connection with the local within a preset time, which indicates that the communication connection between the client and the client in communication connection with the local is disconnected, and the client acquires an IP address of a standby client and establishes communication connection with the standby client according to the IP address of the standby client. Wherein, the IP address of the standby client can be obtained by the modeling control server, if there is one client apart between the standby client and the client. The preset time is set according to an actual situation, and the embodiment of the invention is not limited.

For example, the clients identified as 1#, 2#, 3#, 4# and 5# respectively all open the collaborative modeling task a, and the first queue numbers of 1#, 2#, 3#, 4# and 5# clients are 01, 02, 03, 04, 05 respectively. When the collaborative modeling task A is performed, the 1#, 2#, 3#, 4# and 5# clients are sequentially connected in communication. Due to some reason, the 3# client is disconnected, the 2# client does not receive the feedback information of the 3# client within the preset time, and the 2# client acquires the IP address of the standby client, namely the IP address of the 4# client, and establishes communication connection with the 4# client according to the IP address of the 4# client.

2. The method of claim 1, wherein the determining, according to the first queue number of the client that has started the collaborative modeling task, the client that has started the collaborative modeling task and that is in communication connection with the client comprises:

and determining the client which is in communication connection with the client and has started the collaborative modeling task according to the first queue number of the client which has started the collaborative modeling task and the first queue number of the client.

3. The method of claim 1, wherein the determining, according to a second queue number of the client that has started the collaborative modeling task, the client that has started the collaborative modeling task and that is in communication connection with the client comprises:

comparing the priority of the client with the priority of the client which opens the collaborative modeling task according to the second queue number of the client which opens the collaborative modeling task and the sequence of the second queue number of the client which opens the collaborative modeling task;

if the priority of the client is judged and known to meet a first preset condition, a second preset condition or a third preset condition, determining the client which is in communication connection with the client and already starts the collaborative modeling task, and setting a second queue number of the client;

the first preset condition is that the priority of the client is greater than or equal to the priority of the client with the first queue number in the second queue number ordering order, and accordingly, the determining the client which is in communication connection with the client and has started the collaborative modeling task, and the setting the second queue number of the client includes: the client with the first queue number in the sequencing order is the client which is in communication connection with the client and has started the collaborative modeling task, and the second queue number of the client is set as the second queue number of the client with the first queue number in the sequencing order;

the second preset condition is that the priority of the client is lower than the priority of the client with the second queue number ranked earlier in two adjacent clients with the collaborative modeling task started in the second queue number and is greater than or equal to the priority of the client with the second queue number ranked later, and accordingly, the determining the client with the collaborative modeling task started in communication connection with the client and setting the second queue number of the client includes: the client with the first queue number and the client with the second queue number and the later queue number are clients which are in communication connection with the client and start the collaborative modeling task, and the second queue number of the client is set as the second arrangement number of the client with the second queue number and the later queue number;

the third preset condition is that the priority of the client is lower than the priorities of all clients already starting the collaborative modeling task, and accordingly, the determining the client already starting the collaborative modeling task in communication connection with the client and setting the second queue number of the client includes: and the client with the second queue number for sequencing the last bit is the client which is in communication connection with the client and has started the collaborative modeling task, and the second queue number of the client is set as the new last bit of the second queue number for sequencing.

4. The method of claim 3, further comprising:

receiving request information for finishing the collaborative modeling task, which is sent by the client;

and if the client is judged to be not the client which requests to end the collaborative modeling task, updating the second sequence number of the client with the second queue number being more rear than the second sequence number of the client.
