The invention discloses a software updating system for data transmission and system detection, which is realized by updating related data through a remote control transmission system and writing the related data in an EEPROM (Electronically Erasable Programmable Read-Only Memory) after the related data is detected to be error-free. A system is restarted every time, a system updating program is loaded to an RAM (Random Access Memory) and is used in cooperation with an ROM (Read Only Memory); during the operation of system programs, once the program addresses of an ROM counter and a bug are consistent, the system skips to an address corresponding to debugging data (data related to system updating) loaded in the RAM; and after ending execution, the system returns to an original position of the program and executes following programs. The invention further discloses an updating system for digital household equipment, wherein the updating system for the digital household equipment comprises a remote controller, a remote data receiving module, a status detection module, an EEPROM write-in module, an EEPROM, an RAM loading module, an RAM, an ROM and an ROM skip module. The software updating system for data transmission and system detection is simple and feasible, fast and effective, and beneficial to the promotion of the popularization and the development of digital household electrical appliances and a home network.
Description
technical field [0001] The invention relates to a software upgrading system for data transmission and system detection.
