Description

  The present invention relates to a network system in which data processing devices such as a host computer and a terminal device are connected to each other through a network to enable cooperation processing, and more particularly, a screen display information cooperation method for displaying a network structure by performing cooperation between screen components. , And a linkage method.

  In a system in which a plurality of data processing devices are connected to a network, linkage of screen display information is suitable for various monitoring control systems. For example, in a water treatment plant monitoring and control system, pumps, gates, valves, etc. such as sand basins are monitored and controlled equipment and devices, and monitoring / controlling devices such as pump operating / stopped, faulty, automatic / manual control states, etc. Monitor and control. In the substation monitoring and control system, the monitoring and control device monitors and controls the state of the substation equipment, the state of the receiving / transforming line, the accident, and the like. In such a monitoring control system, when a monitoring screen similar to the monitoring screen by the monitoring application installed in the monitoring control apparatus can be monitored at a monitoring station, generally, a monitoring application (monitoring application on the monitoring control apparatus side) is used. ) A and the monitoring application B on the monitoring station side can display the same monitoring screen and control operations by communicating display data and operation data.

  Other examples of network systems include network-connected video conferencing systems and presentation systems. In these systems, the same screen display information is shared by each computer, and further combined and displayed on one large display. Data processing is performed.

  As described above, in a network system in which screen display information is linked between data processing devices connected to a network, screen display that can efficiently link screen display information and provide flexibility in system construction. The applicant of the present application has already proposed an information linking method (see, for example, Patent Document 1).

  In this cooperation method, a specific state in the transmission side application is linked to the screen information of the reception side application via the network. First, the dispatcher object corresponding to the predetermined key preset in the receiving application via the network based on the predetermined post information receives the status data transmitted from the sender class object incorporated in the transmitting application. . The dispatcher object then selects a proxy recipient object for the receiving application based on the key and passes the state data to the proxy recipient object via the dispatch listener interface. Finally, the proxy recipient object passes the state data to the screen component of the receiving application via the recipient interface. The screen component updates the display based on the received state data.

Moreover, as a new form of the supervisory control system, there is one using a wireless sensor network as shown in FIG. The wireless sensor network uses multiple small microcomputers (sensor nodes) with wireless communication functions and sensor I / O, connects the base station node and the PC, and configures a wireless network between the sensor nodes to provide sensor information. Are sequentially relayed (multi-hop) between the sensor nodes to collect information in the base station, or sequentially send control from the base station to the designated sensor node.

  The sensor network has network structure information in addition to sensor / control information. This is expressed by including an ID indicating a parent node in information from a certain node. Depending on the application, it may be necessary to display the network graph structure as a graph image. The link between nodes needs to be displayed in a coordinated manner, such as the display position is determined by the position of the node at the end point, and the current image display information linkage method does not have a linkage function between components. Can not.

  Also, unlike a normal monitoring control device, in a sensor network, one monitoring point often has a plurality of sensor information. When multiple sensor information for a single sensor node is represented by a single key, the screen component also receives multiple pieces of sensor information. However, if the type of data to be transmitted is different, such as when the mounted sensor varies from node to node, each It is necessary to create corresponding screen parts, which requires a lot of labor and time.

  An object of the present invention is to facilitate the cooperation of a plurality of screen components in a network system in which data processing devices can be linked and connected via a network connection, and the handling is simple even when the type of data to be transmitted varies from node to node. It is to provide a cooperation method and a cooperation method of screen display information.

  In order to solve the above-described problems, the present invention is characterized by the following screen display information linkage method and linkage method.

The data processing device registers a data server that generates screen display information to be displayed by being mounted on its own node or another node, and a GUI component developed by the component definition, and uses the screen on which the GUI component is arranged as the screen definition. A dispatcher that stores and displays GUI parts accordingly,
The dispatcher is
When data comes from the data server or when an operation of a component is performed, a means for acquiring a state from a component that needs to be linked and transmitting the result to another component to link between the components;

And a means for displaying a network structure in which connecting lines are displayed.

  (2) When the data server collectively sends a plurality of sensor values to the screen part, the combination of the sensor value name and the typed value is set as XML or a map type, and the type of the sensor value is set as a key. It has a means for storing a plurality of values and transmitting them to a screen component.

(3) In a network system in which data processing devices are connected to each other through a network to enable cooperation processing,
The data processing device registers a data server that generates screen display information to be displayed by being mounted on its own node or another node, and a GUI component developed by the component definition, and uses the screen on which the GUI component is arranged as the screen definition. A dispatcher that stores and displays GUI parts accordingly,
The dispatcher is
When data comes from the data server or when a part is operated, a state is obtained from a part that needs to be linked, and the result is sent to another part to link the parts;

For the information from a certain node, the display coordinates of the node screen parts of that node and the parent node are acquired in advance, and the current position of the node and the parent node is obtained by transmitting the coordinates to the link part corresponding to that node. And a step of displaying a network structure on which a connecting line is displayed.

  (4) When the data server collectively transmits a plurality of sensor values to the screen part, the combination of the sensor value name and the typed value is set as XML or a map type, and the type of the sensor value is set as a key. The method includes a step of storing a plurality of values and transmitting the values to a screen component.

  As described above, according to the present invention, the cooperation of a plurality of screen parts is facilitated, and the handling is simplified even when the type of data to be transmitted differs depending on the node.

  Specifically, by linking the screen components with the dispatcher, the state of the screen components can be reflected on other screen components, thereby displaying the network structure composed of nodes and links.

  Further, when data consisting of a plurality of name / value pairs is transmitted to the screen component, it can be handled as it is without changing the data type by using XML or map type. For example, when the sensor to be used is changed, the number of parts to be changed between the dispatcher and the screen parts is reduced, and the occurrence probability of defects can be suppressed.

(Embodiment 1)
FIG. 1 is a main part configuration diagram of a data processing apparatus showing an embodiment of the present invention. The data processing apparatus is used as each node of a network by wireless communication, and screen components are linked to display a network structure.

  The configuration in FIG. 1 includes a data server 1 and an HMI (Human Machine Interface) client 2. The data server 1 is functionally configured as a data processing device of its own node or another node, and further in a monitoring control system, a monitoring information processing device of a monitoring control target device, and generates screen display information to be displayed. The HMI client 2 includes a dispatcher 2A, a GUI component 2B, and a receiver 2C, registers a GUI component developed by the component definition, saves a screen on which the GUI component is arranged in the screen definition, and displays the GUI component accordingly.

  The dispatcher 2A provides information for analyzing data, has a tag map that becomes a definition file for assigning a name (tag) to the data, and receives the data by the receiver 2C as shown in FIG. The data is analyzed according to the above and distributed as an object to each GUI component 2B. Further, the dispatcher 2A transmits the operation of the GUI component 2B to the control of the data server 1, and further enables a tag list display on the client based on the tag map.

  Further, the dispatcher 2A has a function of displaying data of the GUI component 2B and accepting a user operation. Specifically, the dispatcher 2A places a component instance on the screen and sets various properties. Further, the data and the component instance are linked by dragging and dropping the tag prepared by the dispatcher 2A.

  The data server 1 enables data communication corresponding to a SOAP (Simple Object Access Protocol) and a TCP socket, and the client 2 acquires connection information by a server definition, and thereby connects to the data server. The SOAP or TCP socket receiver 2C is selected according to the connection method. The receiver 2C relays communication between the dispatcher and the server.

  In this configuration, a method for displaying a network structure by linking screen components will be described. Since the dispatcher 2A can mutually cooperate with the parts, the dispatcher 2A performs the cooperation between the parts. The timing of cooperation is when data comes from the data server 1 or when parts are operated, and these can all be known by the dispatcher 2A. The dispatcher 2A obtains a state from a component that requires cooperation, and performs cooperation by transmitting the result to another component.

  When it is intended to realize the display of the network structure using this, as shown on the left side of FIG. 3, in addition to the node screen part that displays the node, the link screen part that represents the network link by a line is displayed. The same key ID1, ID2 as the node screen parts are allocated. It is assumed that the link screen component can display lines by designating the display coordinates of both end points.

  The information from the node usually includes the parent node ID of the network structure. As shown on the right side of FIG. 3, the dispatcher 2A obtains the display coordinates of the node screen parts of the node and the parent node in advance for information from a node, and a link corresponding to the node (having the same key) Send coordinates to the part. As a result, a line connecting the current position of the node and the parent node is displayed. When information is transmitted from each node, a line connecting each node to the parent node is displayed, and as a result, the network structure is displayed.

(Embodiment 2)
In the present embodiment, a method for collectively transmitting a plurality of sensor values of sensor nodes to a screen component is proposed.

  A plurality of sensor values are sent together as information from the sensor node. At this time, if the types of sensors mounted are different, the data type cannot be determined. Necessary information is a set of sensor value name and typed value. As shown in Fig. 4, this is XML or map type (such as HashMap of Java (registered trademark)), and the name is used as a key. Multiple typed values can be stored.

  In this embodiment, this XML object or map type is used as a data type used in the sensor node tag and the node screen component, so that data can be handled in a unified type even when the mounted sensors are different.
