Abstract

The utility model discloses a device for realizing the clock function of a mobile telephone, and integrating an electronic watch with a mobile phone module. When the mobile phone is in the standby state, a screen enters the sleep state and the backlight goes out; and when the mobile phone is in the shutdown state, the power supply to the screen is cut off. However, the mobile telephone can also display time in the two states. The utility model has the advantages that the time can be seen conveniently even though the screen backlight does not need to be lit in the standby state of the mobile phone, and the power-on is unnecessary in the shutdown state.

Description

A kind of implement device of cell phone clock function

Technical field

The utility model relates to a kind of device of cell phone clock, relates in particular to a kind of time display apparatus under standby status of mobile phone and off-mode.

Background technology

Along with development of times, mobile phone develops to many-sided intelligent direction such as music, video, Digital Video Broadcasting Handheld from single conversation and SMS, but the increase of numerous functions, it is complicated day by day to make that also user's operation becomes, particularly when the user only needs to use one of them simple function, what but become is very complicated, and the most of function of present mobile phone is all realized by software, this just makes most of functions need be at mobile phone power-on, just can operate by keyboard and felt pen under the state that screen is opened.

Time clock feature is the basic function of each mobile phone, though most mobile phone all carries the RTC circuit, adopts the reserve battery power supply, and to keep the real-time clock under the off-mode, the user can see that the time must be with mobile phone power-on, and screen is opened for prerequisite.If this moment, mobile phone was in off-mode, that also needs the longer start process of experience, especially the available machine time of smart mobile phone is longer, this only wants the complexity that seems suitable the user of the time of seeing for one, close the user of mobile phone before particularly getting used to sleeping for those, if get up to want the time of seeing midnight, that is with regard to hell to pay.

Summary of the invention

At the deficiency of prior art, the purpose of this utility model is to provide a kind of time display apparatus under standby status of mobile phone or off-mode, and the user need not light screen or open mobile phone, just can conveniently see the time.

The utility model is achieved by the following technical solution:

For solving the problems of the technologies described above, the utility model comprises mobile module and electronic watch module, the electronic watch module is combined with mobile module, when user mobile phone is in holding state, screen enters sleep state, backlight extinguishing and off-mode, power supply has been closed the power supply to screen, and mobile phone still can normally show the time during this two states.

Product form:

Mobile phone with time clock feature as shown in Figure 1, itself is except having all functions of conventional mobile phone, as conversation, audio frequency, functions such as video have increased the electronic watch module at original mobile module, it can carry out independently timing and demonstration time.

System forms:

This utility model is made up of mobile module and electronic watch module, comprises modules such as LCD, camera, touch-screen and power management in the mobile module.The electronic watch module is by power supply, counter, compositions such as display circuit.Only link to each other between the two by three GPIO, realizing that mobile phone base band chip to the resetting of electronic watch module, is provided with, operations such as calibration, the hardware and software resource consumption all seldom, can not increase the burden of original cell phone system.

Operation principle:

1, when mobile phone power-on, systems soft ware can be calibrated the electronic watch module, so that the inner RTC of itself and mobile module is synchronous.

2, mobile phone is set during the time as the user, systems soft ware can be calibrated the electronic watch module meeting equally, so that itself and the inner RTC of mobile module are synchronous.

3, when mobile phone is in standby and off-mode, the electronic watch module is normally operation and demonstration time in real time still.

Because most of cellphone subscribers though they wish that function is The more the better, also wish simple to operate neither the expert neither the player.Particularly as the little function of this class of time showing, operation is simple more good more for the user.The utlity model has advantages such as simple in structure, easy to operate.

Description of drawings

Fig. 1 is a system architecture diagram of the present utility model;

Fig. 2 is provided with schematic diagram for clock module of the present utility model.

Embodiment

How further specify the utility model below in conjunction with accompanying drawing realizes:

As shown in Figure 1, form, comprise LCD in the mobile module by mobile module and electronic watch module, camera, modules such as touch-screen and power management, the electronic watch module is by power supply, counter, compositions such as display circuit link to each other by three GPIO between the two, to realize mobile phone base band chip resetting to the electronic watch module, be provided with, operations such as calibration, the hardware and software resource consumption all seldom, can too much not increase the burden of original cell phone system.

As shown in Figure 2, when mobile phone base band chip calibrated electronic table module, according to following steps:

1, drag down the about 100ms of GPIO reset, at this moment the electronic watch inside modules that resets circuit should show 12:00 on January 1st, 2005 on the electronic watch display screen.

2, positive pulse of GPIO config output, the electronic watch cursor moves to the time.

3, n positive pulse of GPIO count output, each positive pulse all can add 1 operates, and n sets to such an extent that time and resetting time determine jointly by needs.

4, set up after the time, repeat 2,3 steps, corresponding order according to the moon, day, hour, minute is provided with.

5, after setting up minute, GPIO config exports a positive pulse once more, so that its aforesaid setting comes into force, thereby the electronic watch module is picked up counting on new time basis.

Claims

1. the implement device of a cell phone clock function comprises mobile module and electronic watch module, it is characterized in that: described electronic watch module combines with mobile module, and mobile module has been set up the electronic watch module, carries out independently timing and demonstration time.

2. the implement device of a kind of cell phone clock function according to claim 1, it is characterized in that: described mobile module comprises LCD, camera, touch-screen and power management module, the electronic watch module is made up of power supply, counter, display circuit, links to each other by three GPIO between the two.
