Description
[technical field]
The utility model relates to a kind of mobile phone, specifically a kind of mobile phone of realizing the Auto Power On function.
[background technology]
The start mode of mobile phone mainly contains two kinds at present: one, and manual type, user's manual operation mobile phone is realized mobile phone power-on by pushing the start key; Two, automated manner, mobile phone is provided with the Auto Power On function by software, and user's setting-up time can be realized the timing automatic start.But still there is not the mobile phone that utilizes light-operated principle to realize the Auto Power On function at present.
[utility model content]
The purpose of this utility model is to provide a kind of mobile phone that utilizes light-operated principle to realize the Auto Power On function.The technical solution of the utility model is:
A kind of mobile phone, comprise casing, central processing unit (CPU) and battery, it is characterized in that: this mobile phone has a light-operated circuit device and links to each other with power supply with CPU, described light-operated circuit device comprises light-sensitive element (R), voltage stabilizing didoe (SR1), drive integrated circult 1 (IC1), switch (J), resistance (R1), triode (VT1) and drive integrated circult 2 (IC2), and is in parallel with switch (J) after wherein voltage stabilizing didoe (SR1) negative pole is connected with drive integrated circult 1 (IC1); Drive integrated circult 1 (IC1) is drawn a pin respectively with drive integrated circult 2 (IC2) and is linked to each other with CPU; Be connected resistance (R1) between the base stage of triode (VT1) and emitter, base stage connects light-sensitive element (R), and emitter connects drive integrated circult 2 (IC2), and collector electrode connects drive integrated circult 1 (IC1); Light-sensitive element (R) other end links to each other with switch (J).
Described light-sensitive element can be photo resistance.
Photo resistance in the described light controlling device is to be directly installed on the cell phone mainboard, and casing place opening thereon also embeds the protection eyeglass.
Described switch (J) is the mobile phone power-on mains switch, can manually control, also available software control.
The utility model is by the Auto Power On function of light-operated principle realization mobile phone, and user not setting-up time also can realize mobile phone Auto Power On on daytime, avoids forgetting to start shooting or late inconvenience of starting shooting.The utility model also can reach result of use more flexibly in conjunction with the time Auto Power On is set.The utility model is provided convenience for people, has also enriched the function of mobile phone.
[description of drawings]
Fig. 1 is a light-operated circuit schematic diagram of the present utility model;
Fig. 2 is that the utility model is implemented schematic diagram in conjunction with the light-operated circuit of timed power on/off.
[embodiment]
Provide embodiment of the present utility model below in conjunction with accompanying drawing.With reference to Fig. 1 the utility model light-operated circuit schematic diagram.R is photo resistance among the figure, and R1 is a resistance, and VT1 is a triode, and SR1 is a voltage stabilizing didoe, IC1, IC2 are drive integrated circult, 1,2 conducting during 3 high level of drive IC 1 pin, on the contrary end, 5,6 conductings during 4 high level of drive IC 2 pin, on the contrary end, and J is the mobile phone power-on mains switch.A, B are the battery of mobile phone power supply, for this light-operated circuit provides working power.The control of this switch J available software, the user can select whether to use light-operated start voluntarily.
The overall optical control circuit is connected with cellular phone power supplies, and photosensitive resistance R is in low resistance state (≤1K Ω) when illumination, and triode VT1 conducting produces trigger current and makes diode SR1 conducting, and switch J place monitors level, mobile phone power-on.Behind the start 100ms, CPU sends low level to IC1 pin 3 and IC2 pin 4 respectively, and IC1 pin 1,2 and IC2 pin 5,6 are ended, and mobile phone is in the normal boot-strap state.CPU sends high level to IC1 pin 3 and IC2 pin 4 respectively when shutdown, makes IC1 pin 1,2 and 5,6 conductings of IC2 pin, and mobile phone is in the light-operated circuit reset mode.Photosensitive resistance R resistance very high (〉=100K Ω) is oppositely ended triode VT1 when unglazed, does not have electric current, so diode SR1 is in cut-off state, mobile phone can not be started shooting.
May be in order to deal with rainy weather or mobile phone not in the situation of sensitization place, light-operated start can be in conjunction with other start mode, and start is used simultaneously as timing automatic, shown in Fig. 2 schematic diagram, can start shooting when satisfying one of them condition.
The above only is a preferable embodiment of the present utility model, and all equivalent variations and modifications of being done in the claim scope all should be within protection range of the present utility model.
