Embodiment Construction
[0047] A method for real-time refreshing of process data screens, such as figure 1 As shown, the background service program of the server end and the foreground screen program of a plurality of clients pass the interface definition language definition communication of Slice (Specification Language for Ice, the special language of Ice) provided by the Internet communication platform mode (Internet Communications Engine, Ice) interface. In this embodiment, the tools slice2cpp and slice2cs provided by Ice map the interface definition described in Slice language to the interface definition described in C++ and C# language. The main interface of the program operation in this embodiment is as follows:
[0048] Interface name (slice language)
achiever

int RegisterGraphTag(TAGNAMEARRAY tagNames, string strTopic)
background service program
Foreground screen program
void RaiseDataChanged(TAGVALUECOLLECTION tagPairs)

The invention relates to a real-time refreshing method of process data pictures, comprising the following steps of (1) registration request; (2) registration; (3) publishing of process data points: a data collecting component which is operated at a server side collects values of process data points and when the values of the process data points are updated, a background service program adds the values of the process data points into a list of process data point of pictures of the corresponding d-client side and distributing to the client side; and (4) refreshing the pictures of client side. The method of the invention can ensure that only the process data points the values of which are changed are released to the picture of the client side; each value of each process data point is released to foreground for display from the background and all the details can be captured, thus improving the immediacy and fineness of data display, reducing the resource occupies of ineffective transmission in the network and pictures of the client side simultaneously and solving the immediacy and system loading effectively.
Description
technical field [0001] The invention relates to a process data picture refreshing method. Background technique [0002] As a process machine at the on-site process control level in the metallurgical industry, commonly known as a two-level machine (L2), it is located between the enterprise management layer (L3) and the basic automation layer (L1), with process monitoring and optimization as the main purpose of the process control computer system, it plays a connecting role. [0003] In the application software of the process control computer system, the more popular structure usually adopts the client / server (Client / Server) architecture. Under this structure, the server-side service program is responsible for the collection and processing of process data, and the client-side screen program is responsible for the display of process data. These process data include: basic measurement data from the basic automation layer L1, and derived data generated based on calculations bas...
