Abstract
An experimental electricity meter for blind person electrical teaching comprises a meter body, a measuring unit is arranged in the meter body, and the experimental electricity meter for blind person electrical teaching also comprises a measurement input terminal or a test pen electrically connected with the input terminal of the measuring unit. The experimental electricity meter for blind person electrical teaching is characterized by also comprising several scale salient points and several scale interval Braille indication zones, each scale salient point corresponds to one scale interval Braille indication zone, and each scale salient point comprises an electrical heating element. The experimental electricity meter also comprises a voltage controlled driving unit, the input terminal of the voltage controlled driving unit is connected with the output terminal of the measuring unit, the voltage controlled driving unit comprises several output terminals, and each output terminal is electrically connected with one electrical heating element. According to the utility model, the problem that blind students cannot obtain measuring results in electrical experiments is solved.
Description
Technical field
The utility model relates to experiment ammeter for a kind of blind person's electrical teaching, and it belongs to blind religion apparatus class.
Background technology
According to the requirement of syllabus, the content of blind person's education with record of formal schooling includes the content of electricity rudimentary knowledge, in order to allow blind person learn some necessary electricity knowledges, electricity is a subject that practicality is very strong, in electrical teaching process some simply Experiment of Electrical Engineering be absolutely necessary, also inevitably to use some and measure ammeter, such as voltage table, reometer etc.In the prior art, described electrotechnical measurement ammeter is divided into two classes substantially, one class is pointer, one class is digital, blind person, due to the obstacle of vision, uses such ammeter to do experiment and is difficult to know measurement result, for this reason, this two classes ammeter is all not suitable for blind person's use of imparting knowledge to students, and obviously prior art has further improved necessity.
Summary of the invention
The purpose of this utility model is to provide experiment ammeter for a kind of blind person's electrical teaching, the problem existing to overcome prior art.
Experiment ammeter for a kind of blind person's electrical teaching of the present utility model, comprise table body, in described table body, be provided with measuring unit, also comprise the measurement input terminal or the test pen that are electrically connected to described measuring unit input end, characterized by further comprising several scale salient points and several scale value braille marked areas, each scale salient point is corresponding with a scale value braille marked area, described each scale salient point comprises a heating, also comprise voltage-controlled driver element, the input end of described voltage-controlled driver element connects with the output terminal of described measuring unit, described voltage-controlled driver element comprises some output terminals, each output terminal is electrically connected to a heating.
As preferably, also comprise input polarity braille marked area, described input polarity braille marked area is corresponding with described measurement input terminal or test pen.
Experiment ammeter for this blind person's electrical teaching of the present utility model, by measuring input terminal or test pen, introduce measured parameter, this measured parameter is exported a voltage signal to stating voltage-controlled driver element after measuring unit is processed, voltage-controlled driver element specifies corresponding output terminal output voltage to drive corresponding heating heating according to the size of this voltage signal, blind person student is by touching scale salient point, can feel heating scale salient point, touch again the scale value braille marked area corresponding with this scale salient point and can know measurement result is how many, the utility model has obviously solved blind person student cannot obtain the problem of measurement result in Experiment of Electrical Engineering.
