POWER MANAGEMENT DEVICE FOR ELECTRONIC DEVICE AND ELECTRONIC DEVICE This application claims priority to Chinese Patent Application filed on Apr. 16, 2009, the Chinese Patent Office, Application No. 200920107219.6, entitled "Power Management Device for Electronic Devices and Electronic Devices". The entire contents of which are incorporated herein by reference. Technical field

The present invention relates to the field of power management technologies for terminal devices, and in particular, to a power management device for electronic devices and electronic devices.

Background technique

In the use of electronic devices, people are paying more and more attention to the energy management of electronic devices. Energy-saving electronic devices are promoted and encouraged to use, while high-energy, non-environmental electronic devices are gradually being restricted.

An important energy management method for electronic devices is to divide the working mode of electronic devices into working mode, standby mode and power-off mode. When in the working mode, the electronic device is in the running state, and all components can be powered; in the power-off mode, the power supply system of the electronic device is turned off, all components of the device are in a stopped state, and the power switch needs to be re-opened or connected. Power can be restored to the power supply before the electronic equipment can be re-run and work.

When the electronic device is in the standby mode, the electronic device is in a partially running state, and some components of the device are still running. For example, a personal computer (Persona l Computer, hereinafter referred to as PC) is in a standby mode, and components such as a CPU and an internal power are still in operation. The other components are in a stopped state, so that P can compete for the power consumption of the device. Since the components such as CPU and memory are still running, the state information of the runtime is saved, so when the user re-uses the PC, the PC can be very Quickly return from standby mode to work mode, quickly resume normal operation; or as TV is in standby mode, TV The infrared receiving module of the machine is still in operation to receive the control signal sent by the remote controller, while other functional components are in a stopped state, thereby achieving the purpose of lowering the power consumption of the device, when the user turns on the television using the remote controller. The TV receives the infrared signal to start the TV and resume the TV work. It can be seen that in the above-mentioned electronic device, the functions realized in the working mode are large, the power consumption is large, the power consumption is the least when the mode is in the lower mode, and the power consumption b mode is significantly reduced when the mode is in the mode.

With the development of electronic media devices, more sophisticated electronic terminal devices have emerged, such as digital TV set-top box devices. The basic function of the set-top box is to complete the reception and processing of digital television broadcast signals by decoding and decoding digitally compressed images and sound signals. , output it to the TV monitor and audio equipment to send to the audience. In addition, the set-top box also has a hardware architecture similar to that of a home computer and a dedicated real-time operating system and application software, which can receive data information sent in a digital television broadcasting network to carry out other application services, for example, when the data information of the digital television broadcasting network includes Event information table

(Event Information Table, hereinafter referred to as EIT) information, the set-top box can carry out the Electronic Program Guide (hereinafter referred to as EPG) service, and the user can call up the program list to watch the program to be played at any time, and want to watch the program. The program is scheduled, and the set top box can alert the user at the time of the program broadcast or directly switch to the predetermined program.

In addition, when the HTML information and the picture information are included in the data information in the digital television broadcasting network, the set top box will perform the consulting service, and parse the received HTML text and pictures in the standby state, and then according to the HTML protocol. The way to display, users can view a variety of information services, such as weather forecasts, convenience information and so on.

When the data information in the digital television broadcasting network includes updateable set top box information, such as a new version of the set top box software code, the set top box in the standby state can initiate the upgrade service. Specifically, the software code can be received by the set-top box in the standby state, and the code is stored in a non-volatile manner such as FLASH. On the storage device carrier, a new version of the set-top box software can be used the next time the set-top box is restarted. At present, the power consumption management of the existing set top box is also managed by the above working mode, standby mode and power-off mode, wherein the working mode and the power-off mode are the same as the above-mentioned PC and TV, but the set-top box uses the main chip ( Single On Chip, hereinafter referred to as: S0C) technology, which is to complete the main functions of the set-top box including CPU, video and audio processing on a single chip. For the set-top box in standby mode, it is necessary to be able to perform background processing, and it is necessary to ensure the power supply of modules such as CPU. At this time, the power consumption will be relatively large; and the other processing method is to turn off the power of the module such as the CPU in the standby mode, so that the set-top box cannot handle the background service such as software upgrade in the standby mode, but only in the The user performs software upgrades and the like while watching the program.

In the process of implementing the present invention, the inventor has found that at least the following technical problems exist in the prior art: When the existing power management mode manages electronic devices such as set-top boxes, the background service can only be performed when the user is in normal use, and the influence is affected. The user is working normally. Summary of the invention
