Abstract
The utility model relates to a stepping motor type engineering machinery pointer gauge. A moving coil pointer type dial plate which takes a stepping motor as driving is arranged in a gauge panel. The stepping motor type engineering machinery pointer gauge is characterized in that a liquid crystal display screen is arranged in the gauge panel, the circuit arrangement comprises a control module circuit board which takes a CPU as a processing unit, and stimulation testing signals respectively output by a water-temperature sensor T1, an oil-temperature sensor T2 and an oil-mass sensor L are input into the CPU; a digital-quantity output signal of the CPU presents a liquid crystal display in the liquid crystal display screen through a set mode. On the one end, the utility model retains the pointer type dial plate which takes the stepping motor as driving, on the other hand, the small liquid crystal display is arranged so that relevant information that needs to be warned is conducted liquid crystal display, thereby the displaying and warning effects of the gauge can be improved.
Description
Technical field
The utility model relates to the engineering machinery instrument, a kind of step motor type engineering machinery pointer gauge that is used for showing parameters such as oil mass, water temperature and oily temperature of more specifically saying so.
Background technology
Existing engineering machinery instrument, the dial plate that is used to refer to parameters such as oil mass, water temperature and oily temperature are to adopt the moving-coil type pointer mostly.There are the following problems usually for the mechanical type instrument that this tradition is used:
1, the value number of indicating with pointer is not directly perceived;
2, the ultimate value and the alerting signal of parameters such as oil mass, water temperature and oily temperature can't be warned on pointer watch dial intuitively, are left in the basket easily.
When 3, extraneous light was dark, the pointer of dial plate showed and is difficult to read; And being used for mostly adopting the light source of strong luminous incandescent lamp ﹠ lantern in the dial plate at the pilot lamp that illuminate Various types of data night, its consumed power is big, easy burn-out.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of shock resistance by force, not fragile, the step motor type engineering machinery pointer gauge that adopts single-chip microcomputer to carry out the accurate control of digital quantity signal.
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of engineering machinery pointer gauge that has little liquid crystal display is provided, keep with the stepper motor on the one hand is the pointer dial plate that drives, little liquid crystal display is set on the other hand, the relevant information of needs caution is carried out liquid crystal display, with demonstration and the caution effect that improves instrument.
The utility model technical solution problem adopts following technical scheme:
The utility model step motor type engineering machinery pointer gauge, having in the instrument face plate with the stepper motor is the moving-coil pointer-type dial plate that drives; Its design feature is that LCDs is set in instrument face plate, the circuit setting comprises with CPU being the control module wiring board of processing unit, and cooling-water temperature sensor T1, oil temperature sensor T2 and fuel-quantity transducer L import in the CPU processing unit from the analog detection signal of each output; The digital quantity output signal of CPU processing unit is liquid crystal display with the form of setting in LCDs.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, having kept on the one hand is the traditional pointer dial plate that drives with the stepper motor, and little liquid crystal display is set on the other hand, and the relevant information of needs caution is carried out liquid crystal display, has improved the demonstration and the caution effect of instrument greatly.
2, the utility model increase is provided with liquid crystal display, makes to be shown that value is directly perceived more, the electric energy that increased consumption and little.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model circuit theory diagrams.
Number in the figure: 1 instrument face plate, 2 moving-coils pointer-type dial plate, 3 LCDs, 4 control module wiring boards, 5 connecting lines.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment
Referring to Fig. 1, Fig. 2, in the present embodiment,, remain on that to have with the stepper motor in the instrument face plate 1 be the moving-coil pointer-type dial plate 2 that drives by the version of traditional stepper motor moving-coil pointer-type machinery instrument; Present embodiment is to increase LCDs 3 is set in instrument face plate 1, the circuit setting comprises with CPU being the control module wiring board 4 of processing unit, and cooling-water temperature sensor T1, oil temperature sensor T2 and fuel-quantity transducer L import in the CPU processing unit from the analog detection signal of each output; The digital quantity output signal of CPU processing unit is liquid crystal display with the form of setting in LCDs 3, directly be electrically connected with connecting line 5 between LCDs 3 and control module wiring board 4.
In concrete the enforcement, related device in the control module, comprise on all integrated PCB of the being arranged on control module of the single-chip microcomputer wiring board 4, on LCDs 3, demonstrate various required characters, on function and result of use, replenish mutually with moving-coil pointer-type dial plate 2 and LCDs 3.
Claims (1)
