Description
Technical field
The utility model relates to handheld instrument field, is specifically related to a kind of ammeter with light prompt.
Background technology
Conventional pressure altimeter has: the height indicator of mechanical pointer, be integrated into the height indicator in other large-scale instrument instrument, as the avionics system on aircraft, also have a kind of three kinds of height indicators in wrist-watch that are integrated into.The wherein height indicator function singleness of mechanical pointer, only only has height deixis; The height indicator of Aircraft electric system has the feature such as high precision, high reliability, but that shortcoming is volume is large, cost is high; Be integrated into that height indicator volume in wrist-watch is little, cost is low, the relatively mechanical height indicator of function has also increased the functions such as warning, but also has the shortcomings such as low precision, function are relatively simple, and range of application is single.
Under this background, a kind of high precision, low cost, small size, multifunctional novel altitude indicator instruments and meters are proposed can avoid the shortcoming of above-mentioned height indicating equipment.
Utility model content
The purpose of this utility model is to overcome the shortcoming existing in above-mentioned prior art, provides a kind of precision high, and volume is little, the ammeter with light prompt that cost is low.
For achieving the above object, the utility model is by the following technical solutions: comprise and offer signaling interface that bus data receives and send and the microprocessor board of power input interface, with the baroceptor, display screen, LED, switch and the motor that are connected by bus with microprocessor board respectively.
Described baroceptor is connected with microprocessor board by SPI or I2C bus.
Described display screen is connected with microprocessor board by parallel bus.
Described switch is keyswitch.

Brief description of the drawings
Fig. 1 is composition frame chart of the present utility model;
Fig. 2 is display interface schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1 and 2, the utility model comprises the microprocessor board and the digital baroceptor being connected with microprocessor board by SPI or I2C bus that offer bus data reception and the signaling interface, power input interface and the voltage detecting circuit that send, the OLED display screen being connected with microprocessor board by parallel bus, the LED blue, green, red trichromatism that has with being connected with microprocessor board, is also connected with keyswitch and vibrating motor in microprocessor board.The display interface of OLED display screen comprise electric weight show, highly, temperature and pressure show.
The using method of this device:
1) light prompt: LED lamp is selected three look instructions, and in the time that barometer altitude is more than or equal to 5000m, LED lamp glimmers with blueness; , glimmer with green between 5000m at 3000 meters; Between 1000 meters to 3000 meters, glimmer with redness; Below 500 meters, with red led Chang Liang.
2) vibration prompting: below 500 meters, shake with fixed frequency.
3) manual-lock pilot lamp and vibrations: the short power button of pressing, pilot lamp and vibrations will be closed; Short pressing again, will open.
4) screen locking: long 3s locking button, the screen locking pressed; Vice-minister presses again, unlocking screen.
As shown in Figure 2, ammeter interface comprise electric weight show, highly, temperature and pressure show.Electric weight demonstration is first carried out voltage detecting by detection chip, judges the now magnitude of voltage of battery, and then the corresponding electric weight figure that shows.Electric weight figure shows and magnitude of voltage corresponding relation:
1) magnitude of voltage is more than or equal to 3.7V, shows full lattice;
2) magnitude of voltage, between 3.3V and 3.7V, shows two lattice;
3) magnitude of voltage, between 2.7V and 3.3V, shows lattice;
4) magnitude of voltage, between 1.8V and 2.7V, shows space;
5) magnitude of voltage is being less than 1.8V, automatic shutdown;
Barometer altitude indication range is-999 meters to 9999 meters, within the scope of this, do not show "----".Microprocessor constantly reads current barometer altitude value by spi bus, then this value is shown and is flushed on display screen.Reading of barometer altitude value adopts the mode of temperature compensation first to calculate the force value with temperature compensation, then, by the relation between temperature, pressure and height, calculates barometer altitude value.
When microprocessor detects that barometer altitude within the specific limits, send pwm signal and trigger vibrating motor, thereby make vibration equipment, reach alarm function.
