Abstract
The utility model discloses an electroscope, including shell, angle sensor and singlechip, have the metal pole on the shell, metal peak of the staff end has the pombe, the shell internal fixation has insulating wood based panel, metal pole end is continuous with two angle sensor's pivot respectively, angle sensor all fixes on insulating wood based panel to link to each other with the singlechip through the wire respectively, the cover is equipped with the lantern ring in the pivot, and the lantern ring links firmly with two metal formings respectively. When the pombe on electrified object contact electroscope top, self electrically charged just parts with the metal forming that the lantern ring links to each other on can passing to electroscope's metal forming automatically to the pivot that drives angle sensor is rotated, and angle sensor just detects out the angle, it is said that then the hanks give MCU processing, thereby the size of the electrified volume of object can the ration be measured to the singlechip.
Description
Technical field
This utility model relates to a kind of electroscope.
Background technology
Electroscope is a kind of to detect whether object charged and the instrument of rough estimate carried charge size, and when being verified the metal ball on object contact electroscope top, the electric charge self being with can pass on the tinsel in glass bell jar. Owing to like charges is mutually exclusive, tinsel will separate automatically, open angled.
In prior art, electroscope is opened angularly big I according to two paillon foils and is estimated the size of object carried charge, but can not the size of rational judgment object carried charge.
Utility model content
The purpose of this utility model is to provide a kind of electroscope, it can the size of rational judgment object carried charge, thus solving the above-mentioned problems in the prior art.
A kind of electroscope, including shell, angular transducer and single-chip microcomputer; Having metallic rod on described shell, there is metal ball on metallic rod top; Insulation wood based panel it is fixed with in shell; Metallic rod end is connected with the rotating shaft of two angular transducers respectively; Described angular transducer is each attached on insulation wood based panel, and is connected with single-chip microcomputer respectively through wire; Being set with the collar in described rotating shaft, the collar is connected with two panels metal forming respectively.
When charged object contacts the metal ball on electroscope top, electric charge passes to galvanoscopic metallic rod from metal ball, so that like charges on metallic foil, makes the metal forming being connected with the collar automatically separate, thus driving the axis of rotation of angular transducer; Angular transducer detects deflection angle, after, obtain analogue signal, convert digital signal to then through A/D change-over circuit and give the judgement that single-chip computer control system carries out object carried charge size, thus quantitatively measuring the size of object carried charge.
The beneficial effects of the utility model are: this electroscope, and metal forming is opened angled detection according to angular transducer by it, is processed by single-chip microcomputer, carries out the rational judgment of object carried charge size.
Accompanying drawing explanation
Fig. 1 is the galvanoscopic structural representation of this utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is described angle detection circuitry figure.
Detailed description of the invention
Below in conjunction with the utility model is described in further detail.
In figure: 1-shell, 2-angular transducer, 3-single-chip microcomputer, 4-wire, 5-insulate wood based panel, the 6-collar, 7-metallic rod, 8-rotating shaft, 9-metal forming, 10-metal ball.
As it can be seen, a kind of electroscope, including shell 1, angular transducer 2, single-chip microcomputer 3; Having metallic rod 7 on described shell 1, there is metal ball 10 on top; Insulation wood based panel 5 it is fixed with in shell 1; Metallic rod 7 end is connected with the rotating shaft 8 of two angular transducers 2 respectively; Angular transducer 2 is each attached on insulation wood based panel 5, and is connected with single-chip microcomputer 3 respectively through wire 4; Being set with the collar 6 in described rotating shaft 8, the collar 6 is connected with two panels metal forming 9 respectively.
When charged object contacts the metal ball 10 on electroscope 1 top, self electrically charged meeting pass in the metal forming 9 of electroscope 1, the metal forming 9 being connected with the collar 6 is just separated automatically, thus driving the rotating shaft 8 of angular transducer 2 to rotate, angular transducer 2 just detects angle, then the size of object carried charge can quantitatively be measured transmit data to single-chip microcomputer 3 process, thus by single-chip microcomputer 3.
Two metal formings 9 are originally to be close to, and after charged object contacts the metal ball 10 of electroscope 1, electric charge passes to the metallic rod 7 of electroscope 1 from metal ball 10, so that the upper like charges of metal forming 9 band, therefore metal forming 9 repels each other and opens. When the two panels metal forming 9 being originally close to is opened respectively, two collars 6 being connected with metal forming 9 drive the rotating shaft 8 of angular transducer 2 to rotate respectively, and now angular transducer 2 detects the deflection angle of rotating shaft 8.
After angular transducer 2 detects the deflection angle of rotating shaft 8, obtain analogue signal, convert digital signal to then through A/D change-over circuit and give the judgement that single-chip computer control system carries out object carried charge size.
Above-mentioned single-chip microcomputer adopts AT89C51 single-chip microcomputer, 51 single-chip microcomputer output 0-5v voltages, by angular transducer SCA60C-N1000060 acquisition angles, again through the PCF8591T chip of single-chip microcomputer, the analog quantity that angular transducer exports become digital quantity, and be shown in above 12864 liquid crystal display screens.
