Description

On-site torsion calibration device

Technical field:

The present invention relates to a kind of test and calibration that is used to measure the instrument of torque.

Background technology:

In production line, transport facility and similar field, the torque parameter at scene is measured calibration all very to be paid attention to, because these parameters, both provided the whether foundation of requirement up to specification of product quality, it is again the necessary information main source of design, manufacturing and research of the type product, along with continuous advancement in technology, the differentiation of instrument and meter from analog to digital, and then the widespread use of intellectual instrument till now, at present, the problem of measuring moment of torsion technology and existence thereof embodies a concentrated expression of the following aspects:

On user's demonstration and inputting interface function, dull digital LED, character formula LCD and VFD display mode are only arranged, the operation push-button of its separation, button cause input process loaded down with trivial details, and very easily make mistakes;

On device internal arithmetic processing capacity, be to adopt the single-chip microcomputer order set, complex structure, programming efficiency is low; Software design personnel will change the expense great effort;

On the device hardware capability, the existing Single Chip Microcomputer (SCM) system that adopts needs artificially to strengthen reliability design, thereby R﹠D costs are increased greatly;

Aspect system extension, the on-the-spot test that the existing Single Chip Microcomputer (SCM) system that adopts constitutes does not possess the ability that watchdog routine was seized and revised to online volume, requires simultaneously to realize that with no paper record is also very difficult; And in measuring specialty, measuring technology for current moment of torsion (measurement of power), its signal condition from static state to dynamic expansion, working method changes to high speed rotating from static, value gos deep into to special super large or small direction from standard is common, measuring technique contains the situation of being badly in need of advanced person, high-quality, high reliability invariably for fast changing user market.

Summary of the invention:

Technical matters to be solved by this invention is, a kind of improved on-site torsion calibration device is provided, and it can make the device operation short and sweet, promotes programming efficiency significantly, the high reliability of implement device hardware capability, and can realize the with no paper record of on-the-spot test.

The technical scheme that the present invention solves the problems of the technologies described above employing is: on-site torsion calibration device includes and shows input block and control survey unit, be characterized in: device is provided with touch-screen type unit and small PLC controller, device also is provided with printer, the touch-screen type unit is connected with the small PLC controller through communication interface, the small PLC controller is connected with printer through communication interface, the touch-screen type unit through interface to small PLC controller input operation signal, through small PLC controller acquired signal and after handling, make figure in the touch-screen type unit through interface respectively and show, export in printer prints through interface.

The present invention is on user's demonstration and inputting interface function, adopt touch screen technology, the graphical output of regeneration real-time curve and existing digital display mode are relatively operated more short and sweet, the present invention adopts high-grade miniaturization PLC as controller, greatly promote software design personnel's programming efficiency, shorten the programming time, the high reliability of its PLC far exceeds the single-chip microcomputer in the existing equipment especially, its data storage writing function is for the with no paper record of realizing on-the-spot test provides necessary condition.

Description of drawings:

Fig. 1 is that on-site torsion calibration device of the present invention is arranged synoptic diagram.

Fig. 2 is an on-site torsion calibration device structured flowchart of the present invention.

Embodiment:

With reference to Fig. 1,2, on-site torsion calibration device includes and shows input block 1, control survey unit 2, print-out unit 3, casing 4 and interface 6,7,8,9.

Touch-screen type shows input block 1, on user's demonstration and inputting interface function, adopt the highlighted LCD touch screen technology of current novel built-in embedded TFT, touch-screen type unit 1 includes models such as F940WGOT-TWD, the graphical output of regeneration real-time curve, its front panel that is arranged on casing 4 forms man-machine interface, touch the control screen and can realize the operations function, as start picture, show page or leaf, the input cipher leaf, page or leaf is set, torque curve, speed curves, powertrace, time page or leaf or the like is set, the present invention has substituted the digital LED display mode of Single Chip Microcomputer (SCM) system of the prior art, realized that display technique from the development of low side one dimension to high-end two dimension, makes test operation more short and sweet.

Small PLC controller 2, on device internal arithmetic processing capacity, adopt high-grade miniaturization PLC as controller, as Mitsubishi PLC (FX2N-16MF), this controller has powerful programming module and function command system, can promote software design personnel's programming efficiency greatly, shorten the programming time; This controller has high reliability, also include simultaneously the AC/DC power supply, the isolation adjustment of switch numbers amount, filtering, by a narrow margin, logical process and output monitoring each several part, all embody and the Single Chip Microcomputer (SCM) system of original technology needs the artificial low-quality difference of strengthening designed reliability; Small PLC controller 2 is connected with touch-screen type unit 1 through communication interface 6 (RS-422 serial communication interface), small PLC controller 2 is connected with printer 3 through communication interface 7 (RS-232C serial communication interface), and small PLC controller 2 also is provided with power interface 8 and the signaling interface 9 that is connected sensor.

Printer 3, the present invention adopts built-in embedded printer (model is WH-SA3), and provide communication 232/485 interface, and the back-up storage record of 2000 times several data is provided,, has overcome external defective with quasi-instrument for the with no paper record of realizing on-the-spot test provides operating conditions easily, because in the on-the-spot detection of torque gauge, on-the-spot workshop does not allow to record with the paper notes for a long time, and at this moment, application of the present invention is with the superiority on the abundant display technique.

During operation, touch the control screen, through two-way RS-422 serial communication interface 6, send the instruction of selected function to small PLC controller 2, small PLC controller 2 connects instruction and gathers corresponding signal from signal interface 9, and after calculation process, does real-time graphic presentation through two-way RS-422 serial communication interface 6 at touch-screen type demonstration input block 1, and the duplicated record of data can be provided on printer 3 through RS-232C serial communication interface 7 simultaneously, for the with no paper record of on-the-spot test provides convenient condition.

The present invention adopts the high-grade PLC controller of brand-new Mitsubishi miniaturization, colored highlighted GOT touch screen technology and built-in embedded printer, collection signals collecting, real-time graph show, handle, print, are in communication in one, and be platform, and have characteristics such as broad range of applications, prediction and expansion with the mature technology.
