Description
Affiliated technical field
The utility model relates to detection control technology field, particularly a kind of visual closed-loop control pid parameter regulating system.
Background technology
In a lot of industries, a lot of field, all involve the application of PID Closed loop Control, the early stage of electronic technology development is the adjustment that realizes three parameters of PID by regulator potentiometer mostly, it is to rely on that this mode must have the technical know-how of specialty and abundant practical experience, just can make the closed-loop control effect be adjusted to state of a control relatively preferably.The development of Material Testing Machine industry also is the application that will realize closed-loop control, and have more singularity with respect to the application of other industry, Here it is, and every product all has either large or small system performance difference, when using, the PID closed-loop control to carry out real-time otherness adjustment so at different products, realize PID closed-loop control adjusting with the regulative mode of potentiometer, cause very big inconvenience for actual production and application.Present situation is that the design of some producer has not been a potentiometer set mode, several groups of experience pid parameters of storage in system, then by routine call, the technician can be provided with and calls one of them and test in when debugging, until finding one preferably, this mode has had very big change than the potentiometer mode, improved production efficiency, but it also has weak point, that is exactly the state of a control that can not reach the best fully according to the inherent characteristic of system, is not best scheme on technical standpoint.
The utility model content
The purpose of this utility model is to provide a kind of visual closed-loop control pid parameter regulating system, mainly solves existing program regulative mode can not reach the state of a control of the best fully according to the inherent characteristic of system technical matters.
For addressing the above problem, the utility model is achieved in that
A kind of visual closed-loop control pid parameter regulating system is characterized in that: it is made up of liquid crystal display, main control card, action button, metadata cache, data transmission channel, PID control card, a plurality of capture card and testing machine with topworks; Wherein: this liquid crystal display, action button, metadata cache, data transmission channel are connected with main control card respectively, this data transmission channel is connected with the topworks of testing machine by the PID control card, and the detection signal output terminal of this testing machine connects data transmission channel by a plurality of capture cards respectively.
Described visual closed-loop control pid parameter regulating system, it is characterized in that: there are a plurality of CPU parallel processing tasks in this system, and main control card wherein has two CPU.
By technique scheme, the utlity model has following advantage:
The visual closed-loop control pid parameter of the utility model regulating system has all obtained using checking in different loading characteristic product such as mechanical type transmission (such as electronic universal tester, torsion testing machine, relaxation testing machine etc.) and fluid pressure type loading (such as electro-hydraulic servo universal testing machine, full-automatic pressure testing machine, electro-hydraulic servo pressure-shear test machine etc.), make that the debugging of product becomes simply in the production run, also significantly promoted production efficiency.
Description of drawings
Fig. 1 is an electrical installation schematic diagram of the present utility model.
Embodiment
See also Fig. 1, the utility model discloses a kind of visual closed-loop control pid parameter regulating system.As shown in the figure: it is made up of liquid crystal display, main control card, action button, metadata cache, data transmission channel, PID control card, a plurality of capture card and testing machine with topworks; Wherein: this liquid crystal display, action button, metadata cache, data transmission channel are connected with main control card respectively, this data transmission channel is connected with the topworks of testing machine by the PID control card, and the detection signal output terminal of this testing machine connects data transmission channel by a plurality of capture cards respectively.
When closed-loop control is regulated, main control card is passed to the PID control card with the step signal instruction that is provided with by data transmission channel, obtain instructing back PID control card to give topworks according to operation result output loaded value, main control card sends the feedback numerical value of capture card collection to the PID control card simultaneously, so just constituted close loop control circuit, the CYCLIC LOADING of step instruction is sent by main control card, main control card is stored in the feedback numerical value that collects in the loading procedure in the metadata cache chip, last main control card instructs curve and the stack of feedback data curve to be presented on the liquid crystal display step, in step instruction cycle loading procedure, can revise pid parameter at any time by button, amended effect was presented on the liquid crystal display in the next step instruction cycle cycle.
Capture card of the present utility model will be finished a lot of tasks such as measured collection, data processing, data transmission, all has a CPU to come Processing tasks on each capture card.The main control card of this system has two CPU, tasks such as the collection of finishing digital quantity signal (scrambler orthogonal code signal) and data processing, another is finished liquid crystal display and shows control, button processing, metadata cache, Data Transmission Controlling, load instructions task such as post a letter.
Liquid crystal display in the utility model belongs to outsourcing piece, and different manufacturer's models are different, and the liquid crystal display of different manufacturers can reach the display requirement that this utility model will realize technically.Action button also is the same, is outsourcing piece, and different manufacturer's models also is different.Main control card, capture card, PID control card are the products that Shanghai Canvara Control Instrument Co., Ltd.'s research and development are produced, main control card model: C36M-3V0; Capture card model: C36AN-3V0; PID control card model: C36CH-3V0.
The purpose of this utility model is exactly to solve the visual PID of closed-loop control under the different system characteristic to regulate simple and easy realization.The classical theory that closed-loop control PID regulates is exactly to give step signal of system, the real response effect of detection system then, and best effect is to reach critical conditions.How in conjunction with this theory the response in the closed-loop control adjustment process to be presented on the LCD (liquid crystal display) is the technical matters that will solve; whole PID closed-loop control is regulated will finish data acquisition; data processing; the regulating and controlling computing; load instructions generates; regulate output; output violent change detects; the collection of feedback quantity and storage; instruction and feedback data show on LCD; the input of pid parameter; the periodicity Loading Control; lot of data computing and processing such as the protection detection in the regulating and controlling loading procedure also will guarantee the accuracy of the PID execution cycle T in the Loading Control process simultaneously.For reaching these requirements, this programme has worked out many CPU concurrent working control technology, is embedded in a plurality of CPU a system, finish different tasks respectively, reduced each CPU data volume to be processed, realized that visual PID regulates, and has also guaranteed the accuracy of PID period T.Realized that finally PID regulates the system that can adapt to different qualities, made closed-loop control regulate simple, intuitive again.
Only being the novel preferred embodiment of this use in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
