Abstract
The utility model relates to an engineering machinery intelligent liquid crystal module gauge which is characterized in that a control module circuit board which takes a CPU as a processing unit is arranged, 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 liquid crystal display module is arranged, a digital-quantity output signal of the CPU displays on a liquid crystal screen in the liquid crystal display module through a set panel mode, and a liquid crystal backlight board is arranged at the back of the liquid crystal display module. The utility model is strong in quake-proof capacity and is not easy to be damaged; the digital-quantity signal display through adopting a single chip has higher precision.
Description
Technical field
The utility model relates to the engineering machinery instrument, a kind of engineering machinery instrument that is used for showing parameters such as oil mass, water temperature and oily temperature of more specifically saying so.
Background technology
In engineering machinery, the Displaying Meter of parameters such as oil mass, water temperature and oily temperature is necessary configuration.
In the engineering machinery of using, the instrument dial plate that is used to refer to parameters such as oil mass, water temperature and oily temperature adopts the moving-coil type pointer mostly at present.Mainly there is following deficiency in the mechanical type instrument that this tradition is used:
1, mechanical type meter pointer shock resistance is weak, fragile.
2, electrical parameter is to transmit and control with simulating signal, and precision is difficult to guarantee.
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, adopt single-chip microcomputer to carry out the engineering machinery intelligence Liquid Crystal Module table of the accurate control of digital quantity signal.
The utility model technical solution problem adopts following technical scheme:
The utility model engineering machinery intelligence Liquid Crystal Module table, its design feature is that setting is the control module wiring board of processing unit with CPU, and cooling-water temperature sensor T1, oil temperature sensor T2 and fuel-quantity transducer L import in the CPU control module from the analog detection signal of each output; LCD MODULE is set, and the digital quantity output signal of described CPU control module is shown as liquid crystal display with the panel-form of setting in LCD MODULE, and the back of LCD MODULE is set to the LCD backlight plate.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model shock resistance is strong, and is not fragile.
2, the utility model in LCD MODULE, shows original each parameter information integration that shows by discrete component steering needle and pilot lamp by the chip microcontroller High Accuracy Control.
3, the utility model carries out being connected of simple signal wire between single chip control module and LCD MODULE and LCD backlight plate, and its structure is simpler, cost is lower, and the display device LCDs in the modular structure is a micro-power device.
