Problems solved by technology
However, when using a smart TV with an external power supply, sometimes due to various reasons, the smart TV cannot perform a normal shutdown process. When a fault occurs, it may also cause a sudden power failure, resulting in the failure of the smart TV to shut down according to the normal process
In this case, once the power is restored, the power of the smart TV equipment is suddenly turned on, and the power-on operation is often performed in the traditional smart TV. In this way, on the one hand, the strong peak current will cause certain damage to the smart TV, and on the other hand On the one hand, the sudden power-on may surprise and even frighten the user

The present invention provides a power-on protection method and system for a smart TV, wherein the method includes: when the smart TV disconnects the external power supply, detecting whether the disconnection of the external power supply is abnormal; Write the corresponding power-off identification at a specific location in the non-volatile memory in the smart TV; when the smart TV is connected to the external power supply, it enters a standby state and reads the power-off identification; according to the read out of the Electricity identification, to judge whether the last disconnection of the external power supply is an abnormal disconnection; if it is judged that the last disconnection of the external power supply is an abnormal disconnection, then continue to maintain the standby state of the smart TV. Through this method, when the smart TV is powered on, it can be judged according to the power-off mark whether the last power-off was abnormal, and according to the record of the power-off mark, it can be determined whether the smart TV is turned on or not, so as to ensure the safety of the device and the user. Provide effective protection to prevent the smart TV from suddenly turning on and causing damage to the device or frightening the user.
Description
technical field [0001] The present invention relates to the field of smart TVs, in particular to a method and system for power-on protection of smart TVs. Background technique [0002] In the case that personal computers (PCs) have been intelligentized, and mobile phones and tablet computers have also been intelligentized on a large scale, in order to comply with the trend of "high-definition", "networked" and "intelligent" TVs, smart TVs are also gradually entering the market. our life. [0003] The so-called smart TV, like a smart phone, has a fully open platform and is equipped with an operating system. While enjoying ordinary TV content, users can install and uninstall application software, games, etc. provided by TV manufacturers or third-party service providers. Through such programs, the functions of smart TVs can be continuously expanded and upgraded, and smart TVs can be connected to the Internet, AV equipment, PC, etc., and can obtain program content from various ...
