Abstract
The utility model relates to an industrial control room instrument for displaying a graph. A display screen, an operational key and a knob-type operational key are all arranged on the panel of the instrument; wherein the knob-type operational key comprises a bracket and a rotating shaft which is supported by the bracket; a knob and a turntable are arranged on the rotating shaft and can synchronously rotate; a position sensor for monitoring the position changes of the turntable is fixed on the bracket and is electrically connected with a MPU of the instrument. When the knob is rotated by one degree in the practical use, the position sensor can monitor the position change signal of the turntable and can convert the position signal into electric signal to be transmitted to the MPU; according to different rotating positions of the turntable, the position sensor can be matched with the key to finish the operational functions, such as menu selection, picture switching, data search, curve examination, therefore the utility model is more rapid, more flexible and more convenient in operation than the existing all-key instrument.
Description
Technical field
The utility model relates to the industrial circle control room instrument of graphical display.
Background technology
At present, the industrial circle control room instrument of graphical display, its operating mechanism all is made up of various buttons.Common has numerical key, directionkeys, acknowledgement key, cancel key, function key etc. by key class, the organic assembling of these buttons can be finished a kind of complete operating function, is used for that menu is chosen, function selecting, picture switching, data search, curve are checked, data modification, parameter setting, function configuration etc.Because the graphical instrument function that shows of this class is often very complicated, the branch of function is very many, and the product standard of industrial instrument has limited overall dimension, and more quick button can not be set, thereby the number of times of pressing button in the feasible operation is very many, influences service speed.
Summary of the invention
The utility model is that a kind of quick operating industrial circle control room instrument will be provided.
Be furnished with display screen, operation push-button on the panel of this instrument, it is characterized in that also being furnished with the knob-operated key, this knob-operated key comprises support, with the support is the rotating shaft of supporting, the rotating disk that device has knob and rotates synchronously with knob in rotating shaft, be fixed with the position transducer that the monitoring disk position changes on support, position transducer is electrically connected with the microprocessor of instrument.
Said rotating disk can be grating or coding disk or toothed disk, and position transducer can be photoelectric sensor or contact spring or Hall element or sensitive switch.
Be generally the saving installing space, the bispin button that the knob of device in rotating shaft can adopt coaxial line to install, one of them knob reaches with the synchronous rotating disk that rotates of this knob and is fastened in the rotating shaft, and the rotating disk that another knob reaches and this knob disjunctor rotates synchronously is enclosed within the rotating shaft and rotates.
During use, the knob revolution moves an angle, position transducer just monitors the shift in position signal of rotating disk, and become the signal of telecommunication to be transferred in the microprocessor of instrument the shift in position conversion of signals, according to different turned positions, cooperate button can finish and operating function such as check, because knob-operated continuously and more nimble than button, so can realize the purpose of quick operation as menu selections, picture switching, data search, curve.
Description of drawings
Fig. 1 is a panel schematic diagram of the present utility model;
Fig. 2 is the axial section of a kind of concrete structure of knob-operated key;
Fig. 3 is the grating schematic diagram;
Fig. 4 is the face plate center mark signal of bispin button.
On industrial circle control room instrument face plate 10 shown in Figure 1, be furnished with display screen 11, operation push-button 13 and knob-operated key 12.
The knob-operated key example that Fig. 2 provides is the bispin button structure, it comprises and being used for and the fixing support 7 of back side of panel, with the support is the rotating shaft of supporting 8, tighten intrinsic knob 1 and rotating disk 5 in rotating shaft 8, in this example, rotating disk 5 as shown in Figure 3, it is grating with some breach 9, it can rotate with oppositely free by forward continuously in company with knob 1, be fixed with the reflective photoelectric sensor 6 of monitoring grating rotating on support, reflective photoelectric sensor is electrically connected with microprocessor in the instrument, and it is a pulse signal with the rotational transform of grating, be transferred in the microprocessor, this knob that can rotate continuously generally is applicable to the selection of menu, functions such as the switching of picture.The knob 2 and the rotating disk 3 of another and knob 1 coaxial line are fixed into one, be enclosed within rotation in the rotating shaft 8, rotating disk 3 can be a coding disk, promptly on card, be printed on the encoding strip of conduction, respective fixation on support 7 with instrument in the position transducer 4 that is electrically connected of microprocessor are the conductive reeds that contact with encoding strip, it becomes digital electric signal with the evolution of coding disk, is transferred in the microprocessor, generally be used for data quick search, curve function such as check.Knob 2 is partial rotational knobs of forward and reverse rotation certain angle, and it has a center, and the center is marked on the panel, see Fig. 4, figure intermediate cam shape is labeled as the center, and when knob 2 was rotated away from the center, transducer 4 just monitored the angle of rotation.
Above-mentioned example is removed the industrial circle control room instrument that one of them knob and corresponding rotating disk and position transducer just can obtain single knob-operated.
