High/low voltage protection method and system of TV set with storage battery

Abstract

The invention relates to a high / low voltage protection method and system of a TV set with a storage battery. The method comprises that after that the TV set enters an initialized state, a present battery voltage value of the storage battery of the TV set is detected, and a present chip voltage value of the storage battery is recorded and stored in real time; the voltage of the storage battery is adjusted so that the TV set is stabilized in the lowest or highest working voltage, corresponding lowest and highest chip voltage thresholds are recorded; and the present chip voltage is compared with the lowest and highest chip voltage thresholds, if the present chip voltage is lower than the lowest chip voltage threshold or higher than the highest chip voltage threshold, the TV set enters a standby mode. According to the invention, the voltage of a relatively low level is detected and compared with the corresponding voltage thresholds to protect a screen and mainboard of the TV set; and the method and system are simple in operation, more accurate and safer, and high in practicality.

Description

technical field [0001] The invention relates to the technical field of TV software, in particular to a high and low voltage protection method and system for a storage battery TV. Background technique [0002] TV is one of the most common household appliances in people's daily life. With the continuous development of science and technology, the types of TV are increasing day by day. Among them, battery TV is gradually popular because it brings great convenience to people's mobile life. People's favor. [0003] In the actual use of battery TV, it is easy to cause the TV screen and motherboard to be burned out due to the overvoltage of the battery in many cases, especially for some TV screens with poor production quality, the probability of screen burnout is greater . In order to protect the TV screen from being burned during use, the existing technology generally realizes the protection of the TV screen and the main board by directly comparing the current battery voltage of ...

Problems solved by technology

However, because the voltage of the battery that supplies the TV is generally large, directly measuring the voltage on the battery is not only less accurate, but also prone to the possibility of damage to the meter due to the full bias of the multimeter, and the degree of automation is low, which is difficult for practical applications. brought some inconvenience
