Description

A kind of digital saturated standard cell
Technical field
The utility model relates to a kind of digital saturated standard cell.
Background technology
Standard cell is a laboratory electromotive force standard device commonly used, and it is for preserving and transmit " volt " special a kind of chemical apparatuses.Standard cell is generally made anode with pure mercury (Hg), and cadmium amalgam (12.5%Cd+87.5%Hg) is done negative electrode, cadmium sulfate (CdSO 4) as electrolyte, enclosed package is in the glass tube of H shape then.
Standard cell can be divided into two kinds by the saturation of electrolyte, if electrolyte is that saturated solution then is the saturation type standard cell, otherwise is unsaturation type standard cell.Two types battery principle is all the same with structure, and just characteristic is different.Saturated standard cell electromotive force good stability, the suitable standard of doing uses, but must carry out the temperature correction before using; The internal resistance of unsaturation standard cell is little, and temperature coefficient is little, need not carry out the temperature correction, be convenient in wider temperature range, use, but the electromotive force poor stability.
Commonly used is saturated standard cell, and its electromotive force is about 1.01860, though can not be 1V just, it still be highly stable reliable when needing only each the use it being carried out the temperature correction.Method now commonly used is to utilize mercurial thermometer to measure temperature earlier, and then substitution standard cell temperature correction formula calculates, and draws the standard eleotromotive force under this temperature at last.In this process, because the precision of mercurial thermometer generally can only arrive 0.5 ℃, precision is not very high.Simultaneously, the temperature correction formula more complicated of standard cell, and also mistake in computation can appear often, cause final experimental result error bigger than normal.
How the standard eleotromotive force of Direct Digital demonstration saturated standard cell is the technical barrier of this area.
The utility model content
The technical problem that the utility model will solve provides a kind of digital saturated standard cell of standard eleotromotive force of simple in structure, Direct Digital demonstration saturated standard cell.
For solving the problems of the technologies described above; The digital saturated standard cell that the utility model provides is characterized in comprising: saturated standard cell, controller, link to each other with this controller be used to detect the temperature sensor of said saturated standard cell temperature and the display unit that is used to show the standard eleotromotive force of said saturated standard cell under the Current Temperatures that calculates that links to each other with this controller.
Particularly, said controller is a single-chip microcomputer, at lower cost.
Particularly, said display unit is LED charactron circuit or liquid crystal display screen.
Particularly, for making things convenient for data processing, said temperature sensor is the temperature sensor that is suitable for exporting digital signal.
Particularly, for being convenient for measuring control, said controller also is connected with the input controller that is used to control temperature survey and the demonstration of standard eleotromotive force value.
The technique effect that the utlity model has: the digital saturated standard cell of (1) the utility model, according to the relation of saturated standard cell electromotive force and temperature, utilize temperature sensor and single-chip microcomputer that battery is carried out temperature correction and Direct Digital demonstration.During work; At first utilize temperature sensor to carry out temperature survey, send the digital signal of measuring to the monolithic device then and carry out computing, draw corresponding potential value; Show through charactron or liquid crystal display screen at last, have simple in structure, intuitive display characteristics easily.
Description of drawings
For the content that makes the utility model is more clearly understood, below basis specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation, wherein
The circuit block diagram of the digital saturated standard cell among Fig. 1 embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:
The digital saturated standard cell of present embodiment comprises: saturated standard cell, controller, link to each other with this controller be used to detect the temperature sensor of said saturated standard cell temperature and the display unit that is used to show the standard eleotromotive force of said saturated standard cell under the Current Temperatures that calculates that links to each other with this controller.Said display unit is LED charactron circuit or liquid crystal display screen.
Controller (using the single-chip microcomputer of model as AT89C52) is responsible for carrying out the conversion between temperature and the standard electromotive force of the cell, and its computing formula is:
; Wherein standard electromotive force of the cell when being 20 ℃ is generally provided by manufacturer.
For making things convenient for data processing, said temperature sensor is the temperature sensor that is suitable for exporting digital signal.
During work, at first utilize temperature sensor to carry out temperature survey, send the digital signal of measuring to the monolithic device then and carry out computing, draw corresponding potential value, show through charactron or liquid crystal display screen at last.
The model that temperature sensor uses is 18B20, and this is a resistor-type temperature sensor, and resistance changes with variation of temperature, and measuring range is between-55 ℃ to+125 ℃, and precision can reach 0.1 ℃, is superior to traditional mercurial thermometer.It is simple that this transducer also has a circuit, the characteristics that volume is little.As single wire bus device, form a temp measuring system with it, only need an order wire, very convenient.
Result of calculation can directly show through LED charactron circuit or liquid crystal display screen, and this circuit structure has that design is succinct, and easy to operate, volume is little, and advantage such as be easy to carry.
For being convenient for measuring control, said controller also is connected with the input controller that is used to control temperature survey and the demonstration of standard eleotromotive force value.Input controller comprises two buttons, and corresponding temperature is measured and the electromotive force demonstration respectively.
Display unit adopts 4 charactrons, and wherein temperature shows that only 3 of need are enough, and electromotive force only shows 10 -2-10 -5V.As everyone knows, temperature is in 0-40 ℃ of change procedure, and the standard cell potential change is just 10 -3Just change below the V, and the general measurement of standard cell is also only required is accurate to 10 -4V is so demonstration is to meet requirement of experiment fully like this.Certainly also can show complete standard electromotive force of the cell fully, a kind of method is exactly the figure place that increases charactron, and the volume that this just certainly will increase display screen is unfavorable for installing attractive in appearance with instrument.
Obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not to be qualification to the execution mode of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all execution modes.And conspicuous variation that these spirit that belong to the utility model are extended out or change still are among the protection range of the utility model.
