Detailed Description
The invention provides a module television and a low-power-consumption standby method and system thereof. In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the present invention provides a low power consumption standby method of a modular television, including the following steps:
and S10, when the display screen end receives the standby signal, detecting whether the smart card end is accessed. Specifically, in a normal operating state, the display screen end detects and responds to a remote control signal or a key signal sent by a remote controller or a control panel (namely, a key board arranged on the module television), and when the remote control signal or the key signal is a standby signal (namely, the user inputs the Power key), whether the smart card end is accessed is detected.
The module television comprises an intelligent card end and a display screen end, and the two parts are movably connected. The intelligent card end is an intelligent SOC, runs an intelligent operating system, and realizes multimedia signal processing, DTV/ATV, various application and user interaction functions and management input and output signal interfaces of the television; the display screen end is responsible for functions such as data display and power management.
S20, when the display screen end detects that the smart card end is accessed, the display screen end cuts off the power supply of the smart card end and enables the smart card end to enter a standby state; and when the display screen end detects that no intelligent card is accessed, the display screen end enters a standby state. In other words, when the display screen end is connected with the intelligent card end, the power supply of the intelligent card end is cut off, and the display screen end enters a standby state; and when the display screen end is not connected with the intelligent card end, the display screen end directly enters a standby state.
Specifically, the step S20 specifically includes:
s210, when the display screen end detects that the smart card end is accessed, the smart card end is informed to enter a standby state, so that the smart card end is prepared.
And S220, after receiving the notification of the display screen end, the smart card end performs data processing before standby, enters a standby state after the data processing is finished, and feeds back a standby response message to the display screen end. After the intelligent card terminal is prepared before standby, the information is fed back to the display screen terminal, so that data loss caused by sudden power failure is avoided, and the intelligent card terminal is effectively protected.
And S230, after receiving the standby response message of the intelligent card end, the display screen end disconnects the power supply of the intelligent card end, processes the data before the standby of the display screen end, and enters a standby state and informs the standby machine control module after the data processing is finished. Similarly, after the display screen end is prepared before standby, the standby control module is fed back (notified), so that data loss caused by sudden power failure is avoided, and the display screen end is effectively protected.

The standby control module is independent of the display screen end and the smart card end, and in the embodiment, the standby control module is an 8051 single chip microcomputer.
Therefore, by adopting the method, after the module television is in standby, the display screen end and the function card end of the module television are in a power-off state, only an 8051 single chip microcomputer in the standby state needs to be supplied with power, the standby power consumption of the single chip microcomputer is quite low, the standby power consumption of the module television is greatly reduced, the standby power consumption of the module television gets rid of the restriction of the power consumption of a chip at the display screen end, and the module television can accord with the energy efficiency index and the energy consumption standard of the industry and the country no matter what type of chip is used at the display screen end, so that the energy conservation and emission reduction are realized.
Further, after the step S30, the method further includes the steps of:
s40, after the standby control module enters the standby state, detecting and responding the remote control signal and the key signal of the module television; when a signal for quitting standby is detected, the television quits the standby state, the display screen is powered on, and the remote control signal and the key signal of the module television are not detected and responded.

In the existing standby method, a CPU or a power management chip is usually used to control standby, but even if the CPU or the power management chip turns off the power of most circuits of the television, the CPU or the power management chip still consumes more energy because the CPU or the power management chip needs to be in a standby state. The method provided by the invention is characterized in that a standby control module is independently arranged on the basis of the display screen end and the smart card end of the existing module television, the standby control module is independent of the display screen end and the smart card end and only works when the standby television enters or exits, the standby television is controlled by an 8051 single chip, and the power is saved during standby.
Specifically, as shown in fig. 2, the flow of the module television when entering standby is as follows:
and S100, starting, namely, turning on the module television.
S101, detecting whether a user inputs, namely, detecting whether a remote controller or a control panel is input by the user through keys by the display screen end. If yes, the process proceeds to step S102, otherwise, whether there is user input is re-detected.
S102, whether a power key is pressed or not, namely whether the power key is pressed or not in an instruction input by a user, if yes, the step S103 is executed; if not, the process returns to step S101.
And S103, responding by the display screen end, preparing for standby, and detecting whether the smart card end exists or not.
S104, judging whether an intelligent card end is accessed, and entering step S105 when the intelligent card end is accessed; when no smart card access is made, the process proceeds to step S108.
And S105, informing the smart card terminal to enter standby.
S106, waiting for the response of the smart card end, and entering the step S107 when the smart card end responds; and when the smart card end does not respond, continuously waiting for the response of the smart card end.
And S107, the display screen end disconnects the power supply of the smart card end.
S108, the display screen end enters standby and informs the 8051 singlechip.
And the S109 and 8051 singlechips disconnect the power supply of the display screen end and enter standby.
And S110, completing standby.
Referring to fig. 3, the flow of the module tv exiting the standby mode is as follows:
and S111, starting, namely, the module television is in standby.
And S112, detecting whether a user inputs, namely, detecting whether the remote controller or the control panel is input by the user through keys by the 8051 singlechip. If yes, the process proceeds to step S113, otherwise, whether there is a user input is re-detected.
S113, whether a power key is pressed, namely whether the power key is pressed in an instruction input by a user, if yes, the step S114 is executed; if not, the process returns to step S112.
And the S114 and 8051 singlechips supply power to the display screen end and exit from the standby state.
And S115, the display screen end is electrified and started, and whether an intelligent card end exists or not is detected.
S116, the display screen end judges whether an intelligent card end is accessed, and when the intelligent card end is accessed, the step S117 is carried out; when no smart card access is made, the process proceeds to step S118.
