In one embodiment of the present of invention, the working principle of the invention:
PLC programmable controller has had been widely used for health care, food processing, manufacture since 1969 come out
The various fields such as industry, construction industry, public transport, show business, with industrial robot, CAD and auxiliary manufacture one
Act the three big pillars for forming industrial automation.Traffic lights, elevator, bank ATM, automatically-controlled door, manipulator, music fountain,
Stage Equipment Control, automatic vending machine etc. are all the PLC control cases being frequently seen at one's side.PLC programmable controller technology is automatic
The critical elements for changing industry, obtain universal use in automation equipment.
In view of the shortcomings of the prior art, force value and displacement Value Data real time monitoring are arrived after setting applies force value in 0N
It reaches and applies when force value reaches and record displacement sensor numerical value in real time, two groups of data make the difference to obtain shift value；More importantly originally
Measuring system can compensate for equipment itself and deform, and can measure multi-group data and calculate average value automatically, measurement result is more accurate.
Equipment structure chart introduction: equipment can be in upper and lower, the direction motor adjustment measurement module of front and rear, left and right three and measurement point
Relative position, since trapezoidal screw has self-locking function, handwheel need not lock after being adjusted in place.
Testing touch screen picture is as shown below, first looks for some measurement three times above equipment near the measurement point when measurement,
System averages to obtain the rigid deformation amount of equipment itself automatically, i.e. compensation deflection, is first group of data；Then it is measuring
Three times, system is averaging automatically obtains measurement point deflection for point measurement, is second group of data；System is by measurement point deflection and mends
It repays deflection and makes the difference the practical distortion amount for acquiring measurement point, i.e. conclusion value.
If first group of data and second group of data measure with equipment sheet, conclusion value is regarded as systematic error
Value.
Key point: (1) automatic measurement (2) rigidly measures；
Point to be protected: automation rigid deformation measuring system
Since force value and shift value are the variable for needing to measure, traditional measurement method is a variate-value (force value)
It goes to measure another variate-value (shift value) again when reaching setting value, the continuous mode of first variable (force value) is not easy to
Acquisition, it is easy to it is bigger than setting value, so there are large errors for measurement data.
Programmable controller: it is a kind of electronic system of the electronics of digital operation, specially applies in industrial settings
And it designs.It is used to executing storage logical operation and sequential control, timing, counting using the memory that can be programmed
It is and various types of by the input (I) and output (O) interface, control of number or simulation with the instruction of the operations such as arithmetical operation
Mechanical equipment or production process.
Touch screen: also known as " touch screen ", " touch panel " are a kind of induction type liquid of the input signals such as receivable contact
Crystal device, when contacting the graphic button on screen, the haptic feedback system on screen can be according to the journey of preprogramming
Formula drives various connection devices, is substituted for mechanical push button panel, and produces by liquid crystal display picture lively
Visual and sound effects.
The present invention is by accurately controlling first variable (force value), the numerical value of second variable of instantaneous acquiring, i.e.,
First variable is set to be applied more than setting numerical value, the data acquisition of second variable has been completed, and measurement result is not influenced.
Above is only presently preferred embodiments of the present invention, and of course, the scope of rights of the present invention cannot be limited by this,
Therefore according to equivalence changes made by scope of the present invention patent, still belong to protection scope of the present invention.
