Embodiment Construction
[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0043] The traditional embedded device upgrade method needs to terminate all functions of the device and enter the programming mode. When the new application is downloaded and the old application is overwritten in the memory, the embedded device is restarted, which seriously affects the data collection and processing of the embedded device. And the continuity of the output reduces the real-time monitoring of the power grid and buryes hidden dangers for the safety of the power grid.
[0044] The embedded system in the embodiment of the present invention can be upgraded without affecting the...

The invention relates to the technical field of embedded systems, in particular to an embedded system, and an upgrading method and upgrading equipment thereof. The embedded system comprises an application module, a control module, a communication module and an upgrading management module. The communication module and the application module in the embedded system support multi-process operation; due to the arrangement of the upgrading management module, highest version data are selected when a plurality of different version processes operate simultaneously, low version processes are ended, upgrading is completed under the condition that the continuity of communication data of the embedded system is not influenced, and the safety of a power grid is improved.
Description
technical field [0001] The invention relates to the technical field of embedded systems, in particular to an embedded system, an upgrading method and upgrading equipment thereof. Background technique [0002] As an application form of computer, embedded system is widely used in all walks of life because of its advantages of high reliability, low power consumption, strong real-time performance, small operating system kernel, and multi-tasking support. The applications in it also increased. [0003] In the power system, the embedded device is used as the data collection terminal, and the collected data is processed and uploaded to the background monitoring system to achieve real-time monitoring of the entire system, thereby realizing the purpose of unattended substation. But there are two main problems at present: (1) After a long period of field operation, people find that the functions of embedded devices are defective, or users request to add new functions, so the program ...
