Problems solved by technology

A variety of embedded devices emerge in endlessly, and their functions are becoming more and more powerful, and the software is becoming more and more complex
In this case, the problems in the embedded firmware are unavoidable, and various firmware versions need to be continuously updated, which leads to the continuous dismantling and upgrading of embedded devices. In order to solve this contradiction, the existing technology introduces the Currently, each embedded processor manufacturer has its own online download method, but they are all designed for a single chip. Due to the large and complex systems of various application equipment such as ventilators and anesthesia machines, and the entire system consists of multiple boards, so the existing technology cannot meet the requirements

Abstract

The invention provides a system and a method for online updating of multiple board cards. The system comprises a master display control board, a multichannel gating board, a hardware application system and a kernel application module. The master display control board is provided with an online updating upper computer program and used for updating application programs of application modules; the multichannel gating board is connected with the master display control board and used for communicating a certain application module in the hardware application system with the master display control board; the hardware application system is connected with the multichannel gating board and comprises a plurality of different application modules which are provided with different application programs; the kernel application module is directly connected with the master display control board and provided with a corresponding application program and an online updating lower computer program. According to the technical scheme, the multichannel gating board is additionally arranged between the master display control board and the hardware application system, and consequently the problem that batch updating of huge and complex application apparatus system hardware cannot be realized in the prior art is solved, and online batch updating of the multiple board cards can be realized at one time.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and system for online updating of multiple boards. Background technique [0002] With the continuous development of computer technology, various embedded systems appear in every corner of society and life. Because embedded devices have various advantages such as small size, high performance, portability, and strong pertinence, embedded systems have been widely used in various fields of society. A variety of embedded devices emerge in endlessly, and their functions are becoming more and more powerful, and the software is becoming more and more complex. In this case, the problems in the embedded firmware are unavoidable, and various firmware versions need to be continuously updated, which leads to the continuous dismantling and upgrading of embedded devices. In order to solve this contradiction, the existing technology introduces the Currently, each embedded processor ...
