Problems solved by technology

Once the power failure is triggered, the system enters the protection state, and it cannot reset and start independently; in addition, it will occasionally enter the protection state under the circumstances of the user's artificial quick operation; especially for household power failures and occasional surges voltage drop caused by
These have a negative impact on the user experience

Embodiment Construction

[0025] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0026] see Figure 5 , Figure 5 The system of the smart TV of the present invention is shown schematically. The present invention proposes a smart TV 100, which includes: a power supply 101, a motherboard power conversion system 104, a memory 105, a SOC 106, a storage device 107, a RESET (reset system) 108 and a detection circuit 109. Among them, through the cooperation of the detection signal provided by the detection circuit 109 and the SOC 106, it is detected whether the power supply network is restored, and a trigger signal is provided for predicting whether the user wants to directly power off or shut down the user or the user's power environment is unstable.

[0027] see Image 6 , Image 6 It shows an existing program running process in the booting process. It can be seen that after the system is powered on 301, the running process of the program on the S...

Abstract

The invention provides a smart television and an under-voltage protection fault tolerance method thereof. The smart television comprises a power supply, a main processor, storage equipment, a resetting system and a voltage detection circuit; the power supply supplies power to the main processor, the storage equipment and the resetting system; and the voltage detection circuit is used for detecting whether the power supply voltage of the storage equipment is reduced and triggering and controlling the storage equipment to stop working. In a power-on process, the main processor turns off the response to signals provided by the voltage detection circuit before operating a main program; and the main processor turns on the response to the signals provided by the voltage detection circuit after operating the main program. According to the smart television and the under-voltage protection fault tolerance method thereof, the crash state generated by abnormal power failure in the power-on process can be effectively solved, and the user experience is improved.

Description

technical field [0001] The invention relates to a smart TV, in particular to a smart TV with EMMC. Background technique [0002] With the current development of smart TVs, many smart TVs have EMMC (Embedded Multi MediaCard, embedded multimedia card). EMMC is used to store program codes and other data run by the main CPU of smart TVs. Normal operation is very important. Therefore, many smart TVs adopt a power-down protection mechanism for EMMC. When the smart TV is powered off, the EMMC is controlled to stop working to ensure that the data in the EMMC will not be changed or damaged. [0003] like figure 1 Shown is the EMMC power-down protection block diagram of the prior art, including power supply, mainboard power conversion system, detection circuit, memory system, SOC (system on chip), EMMC system and RESET system (reset system). [0004] figure 2 Yes figure 1 A block diagram of a power supply, including a rectification filter circuit, a PFC circuit, an LLC resonant c...
