Embodiment 1

[0048] For details, please refer to figure 1 It is the schematic structural diagram of the present embodiment. The mobile phone of the present embodiment includes a photovoltaic cell 1, an amplification and compensation circuit 2, a baseband circuit 3, a loudspeaker (i.e. a loudspeaker) 4, a display 5, a baseband chip 31 on the baseband circuit 3 and Baseband chip 32.

[0049] The present embodiment adopts the baseband chip 31 of NXP's model as the OM6357 as the central processing unit, and the analog / digital (A / D) conversion pin of the baseband chip 31 converts the collected analog signal into a light intensity detection module that can The digital signal used; the baseband chip 32 performs digital / analog (D / A) conversion to the numerical value of the light intensity calculated by the light intensity detection module, and converts it into an analog signal that the speaker 4 can use.

[0050] The photovoltaic cell that acts as a light intensity sensor is also used as a power ...

Embodiment 2

[0054] This embodiment is an improvement of Embodiment 1. For the schematic structure diagram of the mobile phone in this embodiment, please refer to image 3 , The mobile phone of the present embodiment includes a photovoltaic cell 1 , an amplification and compensation circuit 2 , a baseband circuit 3 , a speaker 4 , a display 5 , a microcontroller 6 and a baseband chip 32 . The mobile phone of the present embodiment uses the microcontroller as the central processing unit to measure the voltage after amplification and compensation, because the power consumption of the above-mentioned baseband chip 31 as the central processing unit is relatively large (working current tens of milliamperes), and A The / D conversion pin is limited, so this embodiment selects the microcontroller 6 of low power consumption (operating current hundreds of microamperes) to measure the voltage as the central processing unit, and then connects with the baseband circuit 3 through the 12C bus, and then by...

Abstract

The invention relates to a mobile phone which has the function of measuring the intensity of illumination, and belongs to the technical filed of mobile phone intensity of illumination measuring. The illumination is sampled, compensated and amplified by arranging an intensity of illumination measuring device which comprises an intensity of illumination sensor, a compensating and an amplifying circuit center processor; and the intensity of illumination is accounted through an intensity of illumination measuring module. The invention fully utilizes the character that the mobile phone is carried around, thereby solving the technical problem of inconvenience in measuring the intensity of illumination outdoors. The invention is in particular suitable to be used as an assistant measuring device for scientific research, thereby being beneficial for the physical research on atmosphere and the instruction on agricultural production.

Description

technical field [0001] The invention relates to the technical field of measuring light intensity. Specifically, it is a mobile phone that uses a light intensity sensor to measure light intensity. It is mainly used as an auxiliary device for field examinations, and can be used as a reference for setting exposure settings for outdoor photography. Background technique [0002] In recent years, there have been more and more scientific investigations and meteorological monitoring activities, timely obtaining the light intensity of the investigation site, assisting scientific expedition team members and meteorological monitors to do a good job in the early stage of the investigation, making preparations for the next step, and reminding them to do necessary Protective work, for which it is necessary to carry a device for measuring light intensity. There are many existing devices for measuring light intensity, but most of them are separate devices, and the existing measuring device...
