Detailed ways

Referring to Fig. 1, the network-based application collaborative work and decision-making system includes a main assisted search server 1 installed with a server application program and multiple assisted search terminals 2 installed with client application programs and client agent software. The main assisted investigation server 1 regulates the synchronous and asynchronous operations and request information of each assisted investigation terminal 2 through the network, and the main assisted investigation server 1 itself can also serve as the assisted investigation terminal 2 . The communication mechanism between the client application program and the main auxiliary query server 1 is provided by the client agent library. The main assisted search server 1 and the client agent library on the distributed assisted search terminal 2 form a collaborative work engine. The collaborative work engine mainly provides the network information transfer necessary for collaborative work and the logical process decision to ensure the correctness of the collaborative search information. After the secondary development, the client application program can exchange assisted search information with the main assisted search server by calling the client agent library, provide basic data information for the collaborative work, and receive the result information of the collaborative work engine

The operating mode of the above-mentioned client application program and client agent software is a compact integration mode or a layered application mode. When the operation mode adopts the compact integration mode, the client agent software provides each communication function of the collaborative engine to the client application program in the form of a library, and the client application program after secondary development directly realizes the connection with the query server by calling the function function in the library. communication. When the operation mode adopts the application mode of layered structure, the client application program and the client agent software program run separately, and the client application program communicates with the main query server 1 through the client agent software. The compact integrated mode has high efficiency and compact structure. The application mode of the layered structure can realize the flexible topology of the network, and the client agent software and the client software can run on different operating system platforms respectively.

Referring to Fig. 2, the implementation method of network-based application program cooperative work and decision-making system is as follows: 1) initialization of the main assisted search server and assisted search terminal application program, the client agent library on the assisted search terminal is registered in a component manner, and the client application The program can call it in its own secondary development program, and the client application registers the application program information on the assisted investigation server; 2) The client application program of the assisted investigation terminal sends an initiation request to the main assisted investigation server by calling the client proxy library, The request includes the description of the assisted search task, the users to be invited and other necessary description information; 3) After receiving the assisted search initiation request, the main assisted search server sends invitation information to the relevant assisted search terminal users, and waits for the assisted search terminal user's confirmation; 4) when After each assisted investigation terminal user sends back its own confirmation within the specified time, the main assisted investigation server sends a confirmation message of assisted investigation establishment to all valid assisted investigation terminal users. After receiving the confirmation message, the initiating user starts to send the initial data information of the assisted search to the server. After the effective assisted investigation terminal user returns the confirmation information, the main assisted investigation server starts the assisted investigation initialization work; 5) The main assisted investigation server transmits the assisted investigation task information to the effective assisted investigation terminal user, and selects different network transmissions according to the number of assisted investigation end users and the network distribution mode 6) Execution of assisted investigation.

The network transmission mode described in the above step 5) includes multicast and unicast. Multicast: It can enable multi-users to work together to effectively use network bandwidth, and can also solve the defect that broadcast cannot cross routes. It can make the scope of user collaborative work more extensive. Unicast: For a small number of users, or users applying for joining in the process of collaborative work, the unicast method can be used.

Referring to Fig. 3, step 6) in the above-mentioned implementation method includes the following steps: 1) Classification of assisted search operations: assisted search operations include synchronous operations and asynchronous operations. 2) Transmission of assisted search operation: In order to ensure the reliability of operation transmission, because there are few network data in operation data packets, unicast Tcp/IP is used for transmission. The user who needs to submit the operation sends his request to the server by calling the client proxy library, and the server performs different forwarding and decision-making processes according to the type of assisted inquiry. 3) Decision-making of assisted search operation: in the synchronous operation mode, because each user needs to maintain data consistency, only one valid operation can be executed each time. When various users propose different operations, they need to make decisions based on certain methods and principles. User voting or manager decision-making can be adopted. When the result of the decision is made, it is notified to valid users. 4) Execution of cooperative search operation: In synchronous operation mode, each effective client program executes it locally after receiving the decision result. In the asynchronous mode, the user records the operation information of other users locally for browsing operations.

In addition, the present invention also possesses the following auxiliary functions:

1. Assisted investigation query: During the assisted investigation, the user can query the current running status of each assisted investigation through the assisted investigation main server at any time.

2. User rights management: The system can manage registered users on the server. And define the network data encryption information to enhance the security performance when the assisted checking is initialized.

Application examples of the present invention are as follows:

Application of the present invention to transform container image inspection system software, this application system has the following local operation functions before transformation:

1. Perform various image processing on the target image: including scaling, color transformation, edge enhancement, grayscale transformation, etc.

2. Suspect mark the target area

3. Carry out conclusion identification on the target image

Before the transformation, each end user independently inspected and identified through various image processing and suspect marks. However, in the actual working environment, due to the complexity of the item image and the difference in the practical experience of the personnel, it is often difficult to make an identification conclusion. At this time, multiple users are required to conduct comprehensive analysis on a certain suspect target image to make a final decision. The traditional way of using software makes the implementation of this kind of collaborative inspection very difficult. After the transformation, multiple users can perform synchronous or asynchronous operations on a suspected image at the same time. During the inspection process, new users can join at any time, and the system can provide user authority management. And users outside the assisted investigation group can query the progress and results of the assisted investigation at any time. And considering the transformation of other application software, the protocol engine for realizing cooperative operation is designed separately, and organically integrated with the image inspection system, which improves the versatility of the system.

When the present invention is applied, when a certain user encounters suspicious image information that cannot be identified personally and needs assistance from others, he can send a request for establishment of an auxiliary investigation to the main auxiliary investigation server 1 through the client agent module, and at the same time attach the user information that needs to apply for assistance.

When the present invention is applied, after the assisted investigation is established, the initiating user needs to send the local suspect image to the effective assisted investigation terminal client participating in the assisted investigation. Because the locations of the network nodes of each assisted investigation terminal client are different, and the network environment is also different, a combination of unicast or multicast can be used to achieve the best network performance.

When the present invention is applied, after the initialization process of the assisted search is completed, the terminal user of the assisted search can submit his own operation. Assisted search operations are divided into synchronous operations and asynchronous operations. Synchronous operation: There can only be one effective operation at a time, and the image information between the end clients of the assisting search needs to be consistent. Asynchronous operation: Each assisted investigation terminal client can independently operate on the target image, and other assisted investigation terminal clients can know the content of the operation in real time, and can simulate the operation process locally.

In the process of synchronous operation, multiple assisted investigation terminal clients may propose their own different operations, and further decision-making negotiation among assisted investigation terminal clients is required. According to the present invention, the distributed decision-making information of assisted investigation terminal clients can be provided, voting, high-authority assisted investigation terminal client designation, etc. can be adopted, and a good communication mechanism can be provided.

During the process of assisted investigation, there may be situations where the assisted investigation terminal customers accidentally disconnect due to network or other reasons. According to the present invention, when the main assisted investigation server does not receive a confirmation reply from the assisted investigation terminal client or receives a request from the assisted investigation terminal client to withdraw from the assisted investigation, it will send a notification to the current effective assisted investigation terminal client, and each assisted investigation terminal client can update the current assisted investigation user status information.

During the assisted investigation process, there may be other assisted investigation terminal clients who need to query the existing assisted investigation information. According to the present invention, because each assisted investigation client needs the main assisted investigation server to perform regulation and coordination, relevant information can be queried through the main assisted investigation server.

During the assisted investigation process, there may be other assisted investigation terminal clients applying to join an existing assisted investigation. According to the present invention, the new assisted investigation terminal client can apply to the main assisted investigation server, and after receiving a positive reply from the current effective user, the main assisted investigation server will The assisted investigation initialization information and the current assisted investigation operation status are sent to newly joined assisted investigation terminal clients, and each valid assisted investigation terminal client can also update the current assisted investigation terminal client status information. After the onboarding process of new assisted investigation end customers is completed, assisted investigation can continue.

During the assisted investigation process, due to certain circumstances, some assisted investigation terminal clients need to re-synchronize the assisted search initialization information or assisted search status information. According to the present invention, the assisted search terminal client who applies for assisted search can send a request to the main assisted search server. After confirmation by the terminal client, the terminal client applying for assisted investigation sends initialization information and assisted investigation status information to other valid assisted investigation terminal clients through the main assisted investigation server. The establishment and initialization process of this function are somewhat similar.
