Description
Technical field
The utility model relates to household electrical appliance technical field, especially relates to a kind of digital camera of measuring air pressure and height above sea level function that has.
Background technology
Development along with microelectric technique and sensor technology, baroceptor presents chipization, miniaturization and digitized characteristics at present, the length and width of most of air pressure sensor chip are all in 10mm, and some are not that the baroceptor size of chip form is also very little.The power consumption of baroceptor is also very low, is generally 100 to 500uA.Above-mentioned 2 make baroceptor have ready conditions fully to be designed in the circuit of digital camera.On the other hand, air pressure has direct relation with height above sea level again, rule is therebetween grasped by the mankind already, though only the height above sea level of calculating according to air pressure is not an entirely accurate, but also have reference role, so the digital camera of energy measurement air pressure can also estimate the on-site height above sea level of consumer.Present digital camera improves constantly along with popularizing with performance day by day, become people's indispensable carry-on articles of going on a tour, the development in future direction is to be not limited only to take pictures, but to become the multifunction electronic assistant that people go on a tour, have not yet to see the digital camera that can measure air pressure and height above sea level.
Summary of the invention
In view of this utility model purpose is to provide a kind of digital camera of measuring air pressure and height above sea level function that has, and increases the utility function that digital camera is measured air pressure and height above sea level, can go on a tour to the consumer and bring more convenience and enjoyment.
For achieving the above object, the utility model is by the following technical solutions: have the digital camera of measuring air pressure and height above sea level function and comprise digital signal processor, memory, display, a baroceptor, the output of baroceptor links to each other with digital signal processor, air pressure signal is converted to electrical signal transfer gives digital signal processor, digital signal processor links to each other with display with memory respectively, wherein, embedded air pressure of memory and height above sea level calculation procedure, display are used for information demonstration air pressure and the height above sea level numerical value that the receiving digital signals processor transmits.
Further, described baroceptor adopts digital signal baroceptor or analog signal baroceptor.
The beneficial effects of the utility model: compared with prior art, the utility model has increased the air pressure sensing device, pressure information is offered the user with the form of atmospheric pressure numerical value and height above sea level respectively through calculating conversion, calculating the program of air pressure writes according to the algorithm of selected baroceptor, calculating the program of height above sea level writes according to the air pressure of people's grasp and the relation of height above sea level, camera of the present utility model provides a kind of can measure the atmospheric pressure of computing camera carrier present position and the function of height above sea level, satisfy the higher demand outside user's the shooting demand, improved user's quality of the life, strengthened the product use experience of digital camera users greatly, help enlarging the market application foreground of digital camera, be of great practical significance.
Description of drawings
Fig. 1 is a logical construction block diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
As shown in Figure 1, digital camera in the present embodiment comprises digital signal processor 103(DSP), memory 101,102, display 104 and a baroceptor 105, display adopts LCD (LCD), the output of baroceptor 105 links to each other with digital signal processor 103, air pressure signal is converted to electrical signal transfer gives digital signal processor 103, digital signal processor 103 links to each other with display 104 with memory 101,102 respectively.During enforcement, memory adopts normal flash 102(FLASH MEMORY simultaneously) and second generation high speed flash memory 101(DDR2) two memories, described baroceptor 105 adopts digital signal baroceptor or analog signal baroceptor, wherein, normal flash 102 embedded air pressure and height above sea level calculation procedure.Display 104 is used for information demonstration air pressure and the height above sea level numerical value that the receiving digital signals processor transmits.
Specifically, FLASH MEMORY is connected with DSP respectively with DDR2, is storing the program that is used to calculate air pressure and height above sea level among the FLASH MEMORY, and it is medium pending to be moved to DDR2 in digital camera startup back program.Baroceptor is connected with DSP, and after opening measurement function, DSP carries out process of measurement, and baroceptor is opened.Baroceptor can detect the air pressure of place environment, and atmospheric pressure value is converted into the signal of telecommunication passes to DSP, and digital baroceptor can also directly transmit digital signal to DSP, and other baroceptor then is to transmit analog signal to DSP.After DSP receives the air pressure signal that baroceptor transmits, can be according to the air pressure of calculate environment of living in, and converse the approximate reference value of height above sea level of present position according to atmospheric pressure value.Calculation Method is: the program of calculating air pressure is write according to the algorithm of selected baroceptor, calculates the program of height above sea level and writes according to the air pressure of people's grasp and the relation of height above sea level.DSP is connected with LCD, and the result who is used for measuring air pressure and height above sea level outputs to the man-machine interface of LCD.When closing measurement air pressure and height above sea level function, DSP can close baroceptor, to save battery electric quantity.After this function that digital camera is many, the consumer can know the air pressure and the height above sea level of own present position at any time when going on a tour, and giving goes on a tour has increased more enjoyment.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
