Summary of the invention
The object of the invention is provides a kind of electrical quantity display device for the problems referred to above, can meet durable in use on generator, simultaneously also convenient monitoring.
The object of the invention is to be realized by following technical scheme: a kind of electrical quantity display device, it comprises display panel, some blocks are set on panel, several pilot lamp are set in block, on panel, corresponding pilot lamp arranges corresponding Biao Shuo district, the numeral in Biao Shuo district is corresponding one by one with pilot lamp, is provided with relatively testing circuit of sampling in panel, and pilot lamp compares testing circuit with sampling and is connected.
Described sampling comparison testing circuit is formed by connecting by sample circuit module and comparator circuit module, sample circuit module is connected with generator electron plate, gather voltage, electric current, and by with comparator circuit module in predeterminated voltage, current value compare, when corresponding numerical value, make the unlatching of corresponding pilot lamp.
On described sampling comparison testing circuit, be connected with overload protecting circuit, testing circuit is protected.
In described comparator circuit module, can be provided with some comparers, on pilot lamp, correspondence arranges comparer, by predefined value, in corresponding line, can produce low level, makes to be connected on corresponding lamp luminous.
In described comparator circuit module, also can be provided with analog-to-digital conversion module and single-chip microcomputer, wherein D/A converter module is connected with sample circuit, produces digital signal, and through single-chip microcomputer comparison, when reaching preset value, corresponding pilot lamp lights.
Adopt said structure, make in generator operation process, can open-and-shutly see the residing voltage of generator, current value range clearly, convenient monitoring, and display device structure is simple, is difficult for damaging long service life in Generator Vibration.

Embodiment
Embodiment one:
As shown in Figure 1, Figure 3, a kind of electrical quantity display device, it comprises display panel 1, on display panel, arrange one and show block 12, show in block five pilot lamp 3 are set, it is corresponding one by one with pilot lamp that on display panel, corresponding pilot lamp arranges the numeral in 2 ，Biao Shuo districts 2, corresponding Biao Shuo district, in panel, be provided with relatively testing circuit 8 of sampling, pilot lamp 3 compares testing circuit 8 with sampling and is connected.
Described sampling comparison testing circuit is formed by connecting by sample circuit module 4 and comparator circuit module 5, wherein sample circuit module 4 is connected with generator electron plate 6, gather voltage, electric current, frequency or power, and by with comparator circuit module 5 in predeterminated voltage, electric current, frequency or performance number compare, when corresponding numerical value, make the unlatching of corresponding pilot lamp 3.
On described sampling comparison testing circuit, be connected with overload protecting circuit 7, testing circuit is protected.
Further, as shown in Figure 5, in described comparator circuit module, be provided with comparer 9, on corresponding five pilot lamp, correspondence arranges five comparers, by predefined value, in corresponding line, can produce low level, make to be connected on corresponding lamp luminous, by Biao Shuo corresponding to pilot lamp district numeral, identify.By the use of comparer, intuitively simply complete setting the judgement of voltage, electric current, frequency or the performance number of numerical value, directly reflect.
Embodiment two:
A kind of electrical quantity display device, be with embodiment one difference: as shown in Figure 2, Figure 4 shows, when this electrical quantity display device arranges two display panels 1 simultaneously, there are two to show block 12 simultaneously, now, original sample circuit module 4 with in comparator circuit module 5, be connected in series again a comparator circuit module, in the comparator circuit module of this increase, correspondence is provided with pilot lamp 3, can complete like this monitoring when two above data in voltage, electric current, frequency or power.
Further, as shown in Figure 6, in described comparator circuit module, be provided with analog-to-digital conversion module 10 and single-chip microcomputer 11, wherein D/A converter module is connected with sample circuit, produces digital signal, through single-chip microcomputer comparison, when reaching preset value, corresponding pilot lamp lights, and by Biao Shuo corresponding to pilot lamp district numeral, identifies, and by analog to digital conversion, coordinates single-chip microcomputer, by numerical value is set in single-chip microcomputer, intelligent decision, compares its tool of comparer and adds intelligence, and relatively device can arrange most values, more convenient, but cost is higher.
