Description

Smart television screen parameter switching method based on OTA upgrading Technical Field The invention relates to the technical field of intelligent television software upgrading, in particular to an intelligent television screen parameter switching method based on OTA upgrading. Background The screen parameters (screen parameters for short) of the intelligent television cover the core indexes such as resolution, screen type, refresh rate, brightness, color gamut, backlight mode, visual angle, response time and the like, and are key factors for determining the television image quality performance, hardware running stability and service life. The parameter setting is determined by the physical characteristics of hardware, the display technical standard, the system adaptation requirement and the actual use environment, and is matched with the physical device carried by the television. In general, screen parameters of the intelligent television are determined and debugged in the production process of a production line, corresponding screen parameter names are stored in an EEPROM of the equipment, the screen parameter names are read in the starting stage of the equipment, corresponding screen parameter files are loaded for operation, and the screen parameters are not changed after leaving a factory. However, due to the influence of the characteristic difference of devices in the production materials, the problem that the screen of part of the intelligent televisions of the same model is not matched with the carried devices can occur, if the problem is not adjusted in time, the physical devices of the televisions can be seriously damaged, the service life of equipment is shortened, and even the equipment cannot be normally used. Aiming at the problems of the screen parameters found after leaving the factory, the existing solutions in the industry are mainly divided into two types: Firstly, aiming at the non-factory products, the optimal screen parameters are debugged again according to the characteristics of the devices and applied to mass production, and secondly, aiming at the factory-leaving problem equipment, the method of replacing the devices or debugging the screen parameters again is adopted for treatment. The factory return maintenance mode is required to bear high logistics, labor and device replacement cost, after-sales traceability problem equipment and the flow efficiency of factory return one by one are extremely low, meanwhile, because the screen parameter problem only exists in part of equipment of the same model, the screen parameter modification cannot be realized by issuing a conventional model software upgrading package, and if the part of problem equipment is not subjected to targeted processing, the user experience can be directly influenced. Therefore, a technical scheme for realizing accurate upgrading and switching of the screen parameters of the intelligent television in part problems in a software mode without equipment returning is needed, and the follow-up conventional OTA upgrading requirement of the equipment is met while the screen parameter faults are effectively avoided. Disclosure of Invention The invention aims to solve the technical problems that the screen parameter switching method of the intelligent television based on OTA upgrading solves the problems that after the intelligent television leaves a factory, part of equipment is required to be adjusted due to mismatching of screen participation devices, and conventional software upgrading cannot realize screen parameter modification, and the maintenance cost is high and the efficiency is low. The technical scheme adopted for solving the technical problems is as follows: An intelligent television screen parameter switching method based on OTA upgrading comprises the following steps: Receiving a firmware OTA upgrade package of a complete television system and finishing firmware upgrade, wherein the system firmware OTA upgrade package comprises a new screen parameter obtained by debugging an intelligent television risk complete machine with a screen parameter adjustment requirement and a system upgrade application new version of an integrated risk complete machine identification file; And starting a system upgrading application, reading the identification information of the local machine, carrying out matching search with the identification information in the risk complete machine identification file, and executing subsequent screen parameter switching operation or exiting the screen parameter processing flow according to a matching result. According to the scheme, the new screen is integrated into the OTA upgrade package through the upgrade application of the whole machine identification file with risk, the resource pushing is completed by depending on the existing OTA upgrade system of the intelligent television, an additional channel is not required to be built, the equipment matching is carried out based on the unique ide
