Abstract
The invention discloses a kind of absolute value encoder inline diagnosis methods, are related to technical field of automation equipment, program reads the numerical value of absolute value encoder when corresponding mechanism acts in real time, and the numerical value of reading is stored in intermediate store in real time；In corresponding mechanism movement, the numerical value of real time contrast's absolute value encoder and the numerical value being stored in intermediate store before, due to program execution order, real time value should be different from numerical value stored in memory, when correlation data is equal and is more than the delay numerical value of setting, alarm signal is exported.Present invention is mainly applied to general automation equipment position controls to detect absolute value encoder inline diagnosis, can quickly determine abort situation and reason, shorten the equipment fault stopping time, improve equipment efficiency.
Description
Technical field
The present invention relates to technical field of automation equipment, more particularly to a kind of absolute value encoder inline diagnosis method.
Background technique
Absolute value encoder is answered extensively due to the features such as its code-disc coding is unique, strong antijamming capability, high data reliability
For textile machine, irrigation machinery, papermaking printing, water conservancy gate, robot and mechanical arm, port crane, steel smelting
Golden equipment, heavy duty equipment, precision measurement equipment, lathe, food apparatus etc. need the field of Accurate Position Control.
Because absolute value encoder is often related to equipment precision, present most equipment needs people to monitor or operate, difficult
Exempt to will appear carelessness when exception or failure occurs in absolute value encoder, causes unnecessary loss.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of absolute value encoder inline diagnosis method, program is in phase
When answering mechanism action, the numerical value of absolute value encoder is read in real time, and the numerical value of reading is stored in intermediate store in real time；
In corresponding mechanism movement, the numerical value of real time contrast's absolute value encoder and the numerical value being stored in intermediate store before, by
In the reason of the program execution order, real time value should be different from numerical value stored in memory, when correlation data is equal and
More than setting delay numerical value when, export alarm signal；
Wherein, program segment runs timing: numerical value compares program segment and is being stored in intermediate store operation guarantee program just prior to numerical value
Often CL Compare Logic is effective when operation.
Technical effect: present invention is mainly applied to general automation equipment position control detection absolute value encoders to examine online
It is disconnected, it can quickly determine abort situation and reason, shorten the equipment fault stopping time, improve equipment efficiency.
The technical solution that the present invention further limits is:
Further, in actual application, delay numerical value should be according to the connection of live absolute value encoder and drive apparatus
Mode is determined, and when absolute value encoder axis and drive apparatus are directly connected to, then the numerical value that is delayed accordingly reduces, absolute value encoder axis
When being indirectly connected with drive apparatus with gear or chain, then the numerical value that is delayed increases accordingly.
The beneficial effects of the present invention are:
(1) present invention can be reflected to operator when exception or failure occurs in absolute value encoder in a very short period of time, reduce
Loss；
(2) present invention is not necessarily to other investment cost, and after transformation comes into operation, associated class breakdown judge handles 50% or more used time shortening.
Detailed description of the invention
Fig. 1 is flow chart of the invention；
Fig. 2 is exemplary diagram of the invention.
Specific embodiment
A kind of absolute value encoder inline diagnosis method provided in this embodiment, as shown in Figure 1, program is dynamic in corresponding mechanism
When making, the numerical value of absolute value encoder is read in real time, and the numerical value of reading is stored in intermediate store in real time；In corresponding machine
When structure acts, the numerical value of real time contrast's absolute value encoder and the numerical value being stored in intermediate store before, since program is held
The reason of row sequence, real time value should be different from numerical value stored in memory, when correlation data is equal and is more than setting
Delay numerical value when, export alarm signal；Wherein, program segment runs timing: numerical value compares during program segment is stored in prior to numerical value
Between memory operation guarantee normal program operation when CL Compare Logic it is effective.
A simple program logic is done by taking ladder diagram as an example and writes example, as shown in Fig. 2, arrow meaning is that program operation is suitable
Sequence.
In actual use, delay time X determines according to live absolute value encoder with drive apparatus connection type,
For example absolute value encoder axis is directly connected to drive apparatus, because connection structure is there is no factors such as mechanical clearances, then X value answers phase
Reduction should be set, and absolute value encoder axis and drive apparatus are indirectly connected with gear or chain, are existed to eliminate gear or chain
Mechanical clearance caused by erroneous judgement, then X value should increase accordingly, but should not be too large.
The present invention can be reflected to operator in a very short period of time, subtract when exception or failure occurs in absolute value encoder
Small loss；Without other investment cost, after transformation comes into operation, associated class breakdown judge handles 50% or more used time shortening.Such as, exist
Trolley implementation comes into operation up and down for plate heat treating line steel plate shifting and cold bed, and using effect is good
In addition to the implementation, the present invention can also have other embodiments.It is all using equivalent substitution or equivalent transformation formed
Technical solution is fallen within the scope of protection required by the present invention.
