Problems solved by technology

[0003] In the field of industrial process control, due to the complexity and multilateralism of the on-site environment, the data collected by IO measuring points in a certain stage in the distributed control system may not be very stable. When these IO measuring points are configured with alarms, there may be Frequent alerts for these unstable data

Embodiment approach

[0051] Such as figure 1 As shown, the present invention is a kind of alarm suppression method based on timing alarm information, comprising the following steps:

[0052] The controller enters the operation cycle according to the timing and loads the value of the alarm suppression field;

[0053] Judging the value of the current alarm suppression field, and comparing the real-time value of the IO measuring point with each alarm limit configured at the IO measuring point in turn; judging whether a new alarm message is generated at the current moment; generating a new alarm message according to the total number of alarm status word bits warning information;

[0054] Push the alarm information into the alarm queue and wait for the controller to send the information to the upper computer.

[0055] In the method of the present invention, when the alarm suppression field is set to true, the alarm suppression is carried out by comparing with the alarm status word at the previous mom...

Embodiment

[0058] Such as figure 1 As shown, a method for suppressing alarms based on time series alarm information of the present invention comprises the following steps:

[0059] 1) The controller enters the operation cycle according to the timing and loads the value of the alarm suppression field;

[0060] Because the host computer performs value setting operations on the suppression field, at the beginning of each cycle of calculation tasks, the controller needs to judge whether there is an alarm suppression field value issued by the host computer in the real-time value queue; if there is, the alarm suppression field value will be set to The alarm suppression field value is loaded to the alarm enable field of the IO measurement point in the POU file where the IO measurement point is located. If the host computer does not set the alarm suppression field value operation, the previous alarm suppression field value will be used.

[0061] 2) Judge the value of the current alarm suppressi...

Abstract

The present invention provides an alarm suppression method, system, device and storage medium based on timing alarm information. The method includes entering the calculation cycle according to timing and loading the alarm suppression field value; judging the current alarm suppression field value, and comparing the real-time value of the IO measuring point with the Each alarm limit configured at the IO measuring point is compared in turn; it is judged whether new alarm information is generated at the current moment, and if new alarm information is generated, new alarm information is generated according to the total number of alarm status word bits; this method can suppress The alarm information of the measuring points configured with alarms can suppress both dynamic alarms and static alarms.

Description

technical field [0001] The invention belongs to the technical field of controller data processing, and in particular relates to an alarm suppression method, system, equipment and storage medium based on timing alarm information. Background technique [0002] A Distributed Control System (DCS) is a control system specially designed to control complex, large-scale applications in industrial processes. The controller is the brain of the distributed control system, which controls the various subsystems distributed in the control area, and executes the control algorithms and configurations of various devices, and handles network communications between engineering PCs, which are configured through simplex or redundancy implemented to better control the performance of complex processes. The reliability, stability, and high timeliness of the controller are the guarantees for the high reliability, flexibility, coordination, and stability of the distributed control system. Therefore,...
