Because the numerical value of weight of object mainly is to learn by the measurement of weighing device, and the weighing device can be divided into two big classes substantially: the one, mechanical type weighing device (spring balance), another kind is an electronic type weighing device.And these two kinds of weighing devices still have defective to be improved if cooperate actual user mode.
For mechanical type weighing device, when the determinand of want weighing places on the weighing platform of mechanical type weighing device, utilize the elasticity of its inner spring scale to drive reading on pointed index dial panel in it, and because the scale deficiency (600 scales exceed) of the interior scale face of present mechanical type weighing device, can cause the numerical value of pointer indication indeterminate, thereby can't learn the weight of determinand accurately.
General electronic type weighing device can be accurately and is directly obtained the weight numerical value of determinand, and still, electronic type weighing device display panel can show a plurality of different numerical value simultaneously.For example: the transforming numerical (as: some kilograms equal some units) and the time that show transforming numerical (as: platform jin and kilogram), unit of weight and the price of unit of weight on display panel show ... or the like, therefore, can't on the display panel of electronic type weighing device, learn the numerical value of weight of object immediately, thereby use inconvenience.
Summary of the invention
Fundamental purpose of the present utility model is to provide a kind of digital pointer display, promptly has numeral simultaneously and show and high-precision pointer demonstration on the weighing device, allows the user that the method for two kinds of numerical value interpretations is arranged, and can have the precision high advantage of easy identification again.
For reaching above-mentioned purpose, the digital pointer display of the utility model comprises that one varies in weight according to determinand and exports the signal output unit of different electronic signals, one links to each other with signal output unit, converts the micro-computer unit of digital signal output to the electronic signal with its output, links to each other with micro-computer unit with one, converts the digital display unit that numerical value shows to the digital signal with its output.
This micro-computer unit is connected with the pointer unit in addition, this pointer unit comprises digital-to-analogue conversion control module, step motor and pointer, wherein this digital-to-analogue conversion control module links to each other with step motor, and step motor can drive this pointer when rotating and rotates, this digital-to-analogue conversion control module is exported the digital signal of micro-computer unit in digital pulse wave signal mode, and step motor receives the digital pulse wave signal of this digital-to-analogue conversion control module and rotate a fixed angle, this step motor rotation and drive this pointer.
By above-mentioned design proposal, the utility model can have simultaneously on same weighing device that numeral shows and the function of pointer demonstration, allows user's weight numerical value of identification determinand easily.And the utility model is exported digital signal by the digital-to-analogue conversion control module in digital pulse wave signal mode, and the strong and weak or size of this digital signal promptly determines according to the weight of object.Therefore, the digital pulse wave signal that the digital-to-analogue conversion control module is exported is quite accurate, and the turn of this step motor is also accurate thereupon, thereby can increase the scale on the scale face, reach the high purpose of precision, the measured weight numerical precision of determinand is improved.
Graphic key diagram 1 is an operating process synoptic diagram of the present utility model.Fig. 2 is each member synoptic diagram of the utility model.Fig. 3 is an illustrative view of the present utility model.The graphical sysmbol explanation:, (1) signal output unit, (11) electronic signal, (2) micro-computer unit, (21) digital signal, (3) digital display unit, (4) pointer unit, (41) digital-to-analogue conversion control module, (411) digital pulse wave signal, (42) step motor, (421) rotating shaft, (43) pointer, (44) scale face, (5) determinand
Embodiment
See also Fig. 1 and Fig. 2, the digital pointer display of the utility model is interconnected by a signal output unit 1, micro-computer unit 2, a digital display unit 3 and a pointer unit 4 and combines.Wherein, this signal output unit 1 is the signal output unit of circumscribed, be provided with the required loading assembly (not shown) of check weighing in it, when determinand 5 places on this signal output unit 1, the output electronic signal 11 by the induction of this loading assembly (this electronic signal vary in weight and different) with determinand.Micro-computer unit 2 is connected with signal output unit 1, and the electronic signal 11 that signal output unit 1 is exported converts digital signal 21 to, and with digital signal 21 outputs.Digital display unit 3 is connected with micro-computer unit 2, and the digital signal 21 that micro-computer unit 2 is exported converts numerical value to, and this numerical value is shown.
The digital pointer display of the utility model is connected with pointer unit 4 especially in addition on micro-computer unit 2, and this pointer unit 4 is made up of a digital simulation TCU transfer control unit 41, a step motor 42 and a pointer 43; Wherein, this digital-to-analogue conversion control module 41 is exported the digital signal 21 that micro-computer unit 2 is converted in digital pulse wave signal 411 modes.This step motor 42 is connected with digital-to-analogue conversion control module 41, and is mounted on the scale face 44, and the rotating shaft 421 of this step motor 42 is promptly revealed and stretched in scale face 44 centre, and this scale face 44 is circular.This step motor 42 receives the digital pulse wave signal 411 that this digital-to-analogue conversion control module 41 is exported, and drives this step motor 42 by this numeral pulse wave signal 411, makes fixed angle of rotating shaft 421 rotations of step motor 42.One end of this pointer 43 is mounted in the rotating shaft 421 of this step motor 42, and the other end is directed to the scale on this scale face 44, and this pointer 43 promptly rotates with the fixed angle of 421 turns of rotating shaft of step motor 42.
For further specifying the working method and the effect of the digital pointer display of the utility model, the spy makes the following instructions: the signal output unit 1 that places circumscribed when determinand 5, this signal output unit 1 can be exported an electronic type signal 11, this electronic signal 11 converts digital signal 21 to by micro-computer unit 2, and digital signal 21 is sent to digital display unit 3 and pointer unit 4 respectively, at this moment, 3 of this digital display units demonstrate the numerical value that is changed into by digital signal 21, and the shown numerical value that goes out is the weight numerical value of determinand.Simultaneously, the numerical value that the pointer 43 of this pointer unit 4 points on the scale face 44, this numerical value is the weight numerical value of determinand, and pointer 43 indicated numerical value on scale face 44 is the shown numerical value of digital display unit 3, thus the utility model simultaneously numeral show the weight numerical value that shows determinand with pointer.
Below illustrate: as shown in Figure 3, after determinand 5 places the signal output unit 1 of circumscribed, after micro-computer unit 2 processing, demonstrate 20 weight cell by this digital display unit 3; While is by the weight cell of pointer unit 4 with pointer 43 sensings 20 scales, thus the weight numerical value of numeral demonstration simultaneously and pointer demonstration determinand.Therefore, the utility model shows by the auxiliary mutually of digital display unit 3 and pointer unit 4, allow the user have the method for two kinds of numerical value interpretations, thus the weight numerical value of easy identification determinand, can avoid only statistics have shown 3 or pointer show the defective of 4 single display.
