Embodiment 1

[0059] This embodiment provides a diagnostic control method based on the association of oil pressure data in the oil pressure tank of a hydraulic device. This method is applied to various automated control systems. According to the actual change of the process data, when a certain equipment generating process data is abnormal , To report an error to the hydraulic device instead of shutting down, to avoid the impact of the overall shutdown.

[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 data association establishment step 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 oil pressure of the oil pressure tank, and the non-control data is other data associated with the oil pressure of the oil pressure tank , Including one or more of the o...

Embodiment 2

[0111] This embodiment provides a diagnostic control system based on the correlation of oil pressure data from the oil pressure tank of the oil pressure device. The inventive concept of this system is the same as that of the first embodiment. It is applied to various automation control systems. It can be used in a certain When an abnormality occurs in a device that generates process data, an error is reported to the hydraulic device instead of shutting down, to avoid the impact of the overall shutdown.

[0112] Specifically, such as figure 2 As shown, the system includes an oil pressure tank oil pressure data association establishment module and an oil pressure tank oil pressure data association processing module, and the oil pressure tank oil pressure 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 oil...

Embodiment 3

[0131] 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 diagnosis described in Embodiment 1 based on the oil pressure data associated with the oil pressure tank of the oil pressure device. Control method steps.

[0132] Based on this understanding, the technical solution of this embodiment 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. A number of instructions are included to enable a computer device (which may be a personal computer, a server, or a network device, etc.) to perform all or part of the steps of the method described in each embodiment of the present invention. The aforementioned storage media include: U disk, mobile hard disk, read-only memory (Read-Only Memory, ROM), random acc...

Abstract

The invention discloses a diagnosis control method and system based on the oil pressure data association of the oil pressure tank of an oil pressure device, a storage medium and a terminal. The methodcomprises the steps of establishing the oil pressure data association of the oil pressure tank and processing the oil pressure data association, wherein data comprises control data and uncontrolled data, the control data is the oil pressure of the oil pressure tank, and the uncontrolled data comprises one or multiples of oil pressure rising / lowering speed of the oil pressure tank, oil pressure tank oil level, oil returning tank oil level, oil pressure tank oil temperature, servomotor stroke, oil pump operation / stopping time, electromotor current and electromotor voltage. The method comprises the following steps that: establishing an association relationship between the oil pressure of the oil pressure tank and the uncontrolled data; judging data which is collected in real time; and whenmultiple pieces of uncontrolled data do not fall into an ultimate interval of the corresponding value of the oil pressure data of the oil pressure tank, carrying out diagnosis and error reporting onthe revolving speed. By use of the method, 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 toassociation diagnosis.

Description

Technical field [0001] The invention relates to the field of automation control, and in particular to a diagnostic control method, system, storage medium and terminal based on the correlation of oil pressure data of a pressure oil tank of a hydraulic device. Background technique [0002] The controlled object is also called the accused object. In an automatic control system, it generally refers to the equipment or process being controlled as the object, such as the control of reactors and rectification equipment, or the control of heat transfer and combustion processes. From the perspective of quantitative analysis and design, the controlled object is only part of the factors that affect the input and output parameters of the controlled equipment or process, not the entire equipment. In an automatic control system, as a broadly controlled object, actuators (regulating valves) and measurement transmission devices other than the controller (regulator) are included. As a narrowly ...
