MOBILE STATION HAVING MEASUREMENT FUNCTION FOR INTENSITY OF ILLUMINATION AND ULTRAVIOLET RAYS}

The present invention relates to a mobile communication terminal having an illuminance and an ultraviolet ray measurement function. In particular, the mobile communication terminal includes an illuminance and an ultraviolet sensor driving means, and is configured to be detachable from the illuminance and the ultraviolet light sensor so that the terminal itself can be installed without a separate measuring instrument. The present invention relates to a mobile communication terminal having an illuminance and an ultraviolet measurement function for measuring illuminance and ultraviolet light.

Recently, mobile communication terminals are gradually developing into portable information devices by adding various additional functions to simple telephone functions, and input functions such as SMS (Short Message Service), telephone number, schedule, memo and other information are basically provided. Not only that, but now multimedia services such as chat, internet and video on demand are available.

In addition, as the processing speed of the MSM chip, which is a control unit of the terminal, and the data transmission speed with the interface device are improved, and the capacity of the mounted memory is increased, various other functions are added to the original functions of the terminal.

In particular, as a very useful device for users recently, when traveling to the outdoors or the beach, there is a need for a device for measuring the intensity of light (illuminance, UV index, etc.) to people with skin sensitive to sunlight.

In other words, ultraviolet rays are a general term for a wide range of electromagnetic waves with wavelengths ranging from about 397 to 10 nm. Ultra-short wavelength ultraviolet rays are almost indistinguishable from X-rays and are called chemical rays because of their strong chemical reactions. It is so deadly that it is not easy to know in real time how the light intensity changes, and you need a device that can prepare for it.

Of course, there is a UV or illuminance measuring device, but because it is quite expensive and not very small, there is a problem that it is difficult to carry separately a measuring instrument that is not normally carried, such as a mobile communication terminal.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems. The mobile communication terminal includes illuminance and an ultraviolet sensor driving means, and the illuminance and the ultraviolet sensor can be detached and configured so that the terminal itself can be used without a separate measuring instrument. It is an object of the present invention to provide a mobile communication terminal having an illuminance and an ultraviolet measurement function for measuring illuminance and ultraviolet rays.

The present invention for achieving the above object, the illuminance and ultraviolet sensor unit for measuring the illuminance and ultraviolet intensity; A data converting unit converting the illuminance measured by the illuminance and UV sensor unit into a digital signal; A sensor driver for controlling the illuminance and the ultraviolet sensor by a controller; A sensor interface unit for interfacing when the illuminance and the ultraviolet sensor unit are detachably configured; A control command input unit for receiving a control command related to illuminance and ultraviolet light measurement from a user through a keypad or the like; It characterized in that it comprises a control unit for controlling the respective components to perform the illumination and ultraviolet measurement and output the result through a display means such as a speaker or LCD (LCD).

The present invention is a mobile communication terminal that is usually carried to users who are sensitive to ultraviolet rays, to detect and inform the intensity of light (illuminance, ultraviolet light, etc.), and software includes a drive program such as an illuminance and an ultraviolet sensor. By attaching various sensors such as illuminance and ultraviolet rays integrally in hardware, or detachably attaching them through a predetermined interface terminal (USB, receptacle terminal) of the terminal, the illumination and ultraviolet rays can be measured by the terminal itself without a separate measuring instrument. It is a summary of the provision of the apparatus which makes it possible.

That is, the conventional single-piece illuminance measuring instrument, ultraviolet intensity meter, and the like must each have display means for displaying measured illuminance and ultraviolet values, a means for embedding a battery, a user interface means, and the like. There are many overlapping components.

In addition, since the control unit (MSM chip) of the mobile communication terminal has a feature capable of various operations by a program, in the present invention, it is possible to use the hardware means overlapped with each other in the components of the mobile communication terminal and each measuring device. Compared with the cost of purchasing a measuring instrument, the same measurement can be performed at a very low cost and it is easy to carry, thereby improving user convenience.
