Embodiment 1

[0050] This embodiment provides a diagnostic control method based on the data association of the control object. This method is applied to various automatic control systems. According to the actual change of the process data, when an abnormality occurs in a device that generates process data, the control object can be checked. Report errors instead of downtime to avoid the impact of overall downtime.

[0051] Specifically, as figure 1 As shown, the method includes a data association establishment step S1 and a data association processing step S2. The step of establishing data association includes the following sub-steps:

[0052] S11: Establish data association, the data includes at least one control data and at least one non-control data; the main control data is the main monitoring control data and control basis of the control object, and the non-control data is related to Other data associated with the control data.

[0053] Wherein, both the control data and the non-con...

Embodiment 2

[0101] This embodiment provides a diagnostic control system based on the association of control object data. The inventive concept of this system is the same as that of Embodiment 1, and it is applied to various automatic control systems. When the equipment is abnormal, it will report an error to the control object instead of shutting down, so as to avoid the impact caused by the overall shutdown.

[0102] Specifically, such as figure 2 As shown, the system includes a data association establishment module and a data association processing module, and the data association establishment module includes:

[0103] Data association unit: used to establish the association relationship of data, the data includes at least one control data and at least one non-control data; the main control data is the main monitoring control data and control basis of the control object, and the non-control data The control data is other data associated with said control data;

[0104] Limit interva...

Embodiment 3

[0117] Based on the implementation of Embodiment 1, this embodiment also provides a storage medium on which computer instructions are stored, and the computer instructions execute the steps of the diagnostic control method based on the association of control object data described in Embodiment 1 when running.

[0118]Based on this understanding, the technical solution of this embodiment is essentially or the part that contributes to the prior art or the part of the technical solution can be embodied in the form of a software product, and the computer software product is stored in a storage medium. Several instructions are included to make a computer device (which may be a personal computer, server, or network device, etc.) execute all or part of the steps of the method described in each embodiment of the present invention. The aforementioned storage medium includes: U disk, mobile hard disk, read-only memory (Read-OnlyMemory, ROM), random-access memory (RandomAccessMemory, RAM)...

Abstract

The invention discloses a diagnostic control method and system based on control object data association, a storage medium and a terminal. The diagnostic control method comprises a data association establishing step and a data association processing step, wherein the data processing step comprises the following substep that data collected in real time is judged, specifically, when the value of certain critical non-control data and / or the values of a plurality of non-control data does or do not fall within a limit interval of corresponding values of control data, it is considered that the control data and the associated non-control data thereof do not conform to relevant association rules, and diagnosis and error reporting are performed on the control data. According to the diagnostic control method and system based on control object data association, the storage medium and the terminal, diagnostic control is performed according to the characteristics of data association, so that diagnosis is performed when control object data is abnormal, no corresponding control is directly performed, only after the association analysis is performed on the relevant data, corresponding diagnostic control is performed, and a control system fault or a control failure due to defects can be effectively avoided. The application of the diagnostic control method and system based on control object dataassociation, the storage medium and the terminal have a profound impact on a conventional automatic control technology.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a diagnosis control method, system, storage medium and terminal based on control object data association. Background technique [0002] The control object is also called the controlled object. In the automatic control system, it generally refers to the controlled equipment or process as the object, such as the control of reactors and rectification equipment, or the control of heat transfer process and combustion process, etc. From the perspective of quantitative analysis and design, the control object is only a part of the factors affecting the input and output parameters of the controlled equipment or process, not all of the equipment. In the automatic control system, as a generalized control object, actuators (regulating valves) and measuring and transmitting devices other than controllers (regulators) are included. As a control object in a narrow sense, its end parameters (i...
