Embodiment Construction

[0069] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0070] Such as figure 1 As shown, a method for realizing DCS (Distributed Control System) alarm information filtering display and historical query includes the following steps,

[0071] S1, connect to the DCS alarm server;

[0072] Step S1 specifically includes the following steps:

[0073] (101) read configuration file information, set up connection with DCS alarm server by socket; Configuration file includes the IP address of server, port number and redundant label; Redundant server is redundant server when redundant label is true, when redundant label is false is a single server;

[0074] (102) If the DCS alarm service is a redundant server, two client objects are generated, and the two c...

Abstract

The invention provides a method of realizing DCS (Distributed Control System) alarm information filtering display and historical querying. The method comprises the following steps: S1, connecting a DCS alarm server; S2, carrying out alarm information display filtering on the basis of a filtering algorithm; S3, confirming alarm information; S4, displaying the alarm information in real time; and S5,establishing an alarm querying interface. According to the method, storage and sorting of the alarm information and a processing method of exceeding the size of a storage memory are considered, running personnel can conveniently carry out filtering display of the alarm information, and the running personnel filter out unimportant alarm information in the alarm display interface.

Description

technical field [0001] The invention belongs to the field of industrial automation and relates to a method for realizing DCS alarm information filtering display and historical query. Background technique [0002] Alarms are generally divided into system alarms, process alarms, and operation alarms. From the time of system alarm to the alarm that occurs when the system equipment of DCS (Distributed Control System) fails, it can monitor the entire DCS system in real time, including the operator station, control station, network, IO hardware, etc. According to the process index, the abnormality of the production process data will be alarmed. The operation alarm is an alarm means for operators to manually intervene in the process. [0003] The alarm is an important tool to remind the operation work at the first time as the abnormality sent by the DCS system in the production condition. As an automatic control system for process technology, DCS will generate a large amount of ...
