Embodiment 1

[0059] This embodiment provides a diagnostic control method based on the association of hydraulic unit speed data. This method is applied to various automatic control systems. According to the actual change of process data, when an abnormality occurs in a certain equipment that generates process data, the hydraulic unit Report errors instead of shutdowns to avoid the impact of overall shutdowns.

[0060] Specifically, such 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:

[0061] S11: Establish an association relationship of data, the data includes one control data and at least one non-control data; the control data is the speed, and the non-control data is other data associated with the speed, including speed increase / decrease One or more of speed, guide vane opening, servomotor stroke, circuit breaker position, generator o...

Embodiment 2

[0111] This embodiment provides a diagnostic control system based on the association of hydraulic unit speed data. The inventive concept of this system is the same as that of Embodiment 1. It is applied to various automatic control systems and can generate process data at a certain time according to the actual change of process data When the equipment is abnormal, it will report an error instead of shutting down the hydraulic unit to avoid the impact of the overall shutdown.

[0112] Specifically, such as figure 2 As shown, the system includes a rotational speed data association establishment module and a rotational speed data association processing module, and the rotational speed data association establishment module includes:

[0113] Data association unit: used to establish an association relationship of data, the data includes one control data and at least one non-control data; the control data is the speed, and the non-control data is other data associated with the spee...

Embodiment 3

[0131] Based on the realization of Embodiment 1, this embodiment also provides a storage medium on which computer instructions are stored, and when the computer instructions are run, the steps of the diagnostic control method based on the association of hydraulic unit speed data described in Embodiment 1 are executed .

[0132] 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 (RandomAccess...

Abstract

The invention discloses a diagnosis control method and system based on hydropower unit revolving speed data association, a storage medium and a terminal. The method comprises a revolving speed data association establishment step and a revolving speed data association processing step, wherein data comprises control data and uncontrolled data, the control data is revolving speed, and the uncontrolled data comprises one or multiple of revolving speed rising / lowering speed, guide vane opening degree, servomotor stroke, circuit breaker position, electric generator output and working head. The diagnosis control method comprises the following steps that: establishing an association relationship between the revolving speed and the uncontrolled data; judging data which is collected in real time; and when multiple pieces of uncontrolled data do not fall in an ultimate interval of the corresponding value of the revolving speed data, carrying out diagnosis and error reporting on the revolving speed. By use of the method, according to the characteristics of revolving speed data association, diagnosis control is carried out, control is not carried out when the revolving speed data is subjectedto diagnosis exception, and control failure brought by sensor and control system faults or defects can be effectively avoided since control is carried out after the data is subjected to association diagnosis.

Description

technical field [0001] The invention relates to the field of automation control, in particular to a diagnostic control method, system, storage medium and terminal based on association of hydraulic unit speed data. 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 pa...
